2022-85     CONSENT AGENDA:
  A. Approval of Minutes       City Clerk
SUMMARY OF REQUEST: To approve the minutes of the August 23, 2022 Regular
Meeting and the August 31, 2022 Special Commission meeting.
STAFF RECOMMENDATION:          To approve the minutes.
  B.   Getty Street Study Engineering Agreement Public Works
SUMMARY OF REQUEST: Staff is requesting authorization to enter into an
agreement with the cities of Norton Shores and Muskegon Heights to share the
cost of the Getty Street Traffic Study.
Conversion of four-lane roads, such as Getty Street, to three-lane roads have
been proven to be safer and to provide better access or non-vehicular users
with little or no impact to travel times when properly studied and executed. Staff
feels that Getty Street could be a great candidate for this treatment, and has
worked with Norton Shores and Muskegon Heights to solicit a study to determine
if the project should move forward.
Presented to you tonight is a three-party shared engineering services agreement
with the cities of Norton Shores and Muskegon Heights. The agreement
designates our staff as the lead contacts for the project, designates Muskegon

                                         Page 1 of 4
as the lead agency for payment, and requires Norton Shores and Muskegon
Heights to pay their portions to Muskegon based on the centerline miles of Getty
Street in each community. The agreement has been reviewed by the City
attorney, and has already been approved by the city commission of Norton
Shores and Muskegon Heights at prior meetings.
Award to the consultant helping with the traffic study was approved at the
August 9, 2022 Commission Meeting. The agreement presented tonight has a
lower cost to the City than the original request, due to how the cast sharing is
split among the three communities.
AMOUNT REQUESTED: N/A (Approved 8/9/22)                  AMOUNT BUDGETED: $50,000
FUND OR ACCOUNT: 202 (Major Streets)
STAFF RECOMMENDATION:           To authorize staff to enter into an agreement with
the cities of Norton Shores and Muskegon Heights to share the cost of the Getty
Street Traffic Study.
  C. 30” Water Main Meter        Public Works/Water Filtration Plant
SUMMARY OF REQUEST: A water meter is needed on the new 30” water main
near the Water Filtration Plant. Prein & Newhof have provided an agreement for
engineering services for the design, bidding, and construction phases of this
project.
A 30” water main was recently constructed from the Water Filtration Plant to the
Muskegon Channel. While the primary purpose of this water main was to provide
a second connection to the Muskegon County Northside water system, it also
serves the City of Muskegon’s water system.
An existing water meter near the channel measures all water flow into the
Muskegon County Northside water system, but it does not capture any water
used between the channel and the Water Filtration Plan. Installing a water
meter near the Water Filtration Plant will measure all the water flowing through
this main, both to the Muskegon County Northside system and to the City.
Metering this water as it leaves the Water Filtration Plant is critical to overseeing
water plan operations, managing the water fund, and ensuring regulatory
compliance.
As part of the Water Filtration Plan’s Reliability Study, Prein & Newhof
investigated two options for metering this water. Because of Prien & Newhof’s
familiarity with this project from their work developing these two options, we did
not solicit proposals from other firms. The proposal includes engineering services
during the design, bidding, and construction phases of the water meter project.
The construction portion of the project will be posted for bids and presented to
the Commission for approval at a later date.
This project is a budgeted capital improvement project for FY 2022-23.

AMOUNT REQUESTED: $41,000                     AMOUNT BUDGETED: $150,000
FUND OR ACCOUNT: 591-901-801-092034
STAFF RECOMMENDATION:             To authorize staff to enter into an agreement with
Prein & Newhof for a not to exceed cost of $41,000.00 for engineering services
related to the installation of a water meter near the Water Filtration Plant.
  D. Interim City Manager Stipend City Manager
SUMMARY OF REQUEST: Extend stipend paid for the additional duties being
performed in the Interim City Manager role.
The $450 weekly salary stipend is set to expire on September 30, 2022. It is being
proposed to extend the stipend for a one month time period, ending October
29, 2022 to allow time for the new City Manager to get settled into the position
with the assistance of the Interim Manager. If the Interim Manager is selected,
the stipend will cease once a contract is negotiated and accepted by the City
Commission.
AMOUNT REQUESTED: $1,800              AMOUNT BUDGETED: Included in salary line
FUND OR ACCOUNT: 101-10172-5100
STAFF RECOMMENDATION:           To approve the weekly stipend as presented.
Motion by Commissioner Ramsey, second by Commissioner Hood, to accept the
consent agenda as presented.

Commission Meeting Date: October 25, 2022              Title: Sale – 653 Yuba

Submitted By: Hope Griffith                            Department: Planning Department

Brief Summary: City staff is seeking authorization to sell the City owned vacant lot to Ramos
Enterprises LLC.

Detailed Summary: Ramos Enterprises LLC Crowley will be constructing a commercial structure
on the lot owned by the City of Muskegon within eighteen (18) months. The property is zoned B-4
(General Business). The buyer made an offer of $3,000 which is less than 75% of the True Cash
Value (TCV) per policy (TCV is $4,600 @ 75% would be $3,450). This property does have direct
access to the City water & the storm sewer. The sanitary sewer would have an added expense to
the buyer as it would need to go uphill where the residential homes are located. There has been no
interest in developing this property. The City has owned this property since 1997. This property is a
popular dumping site, and the sale would alleviate the City’s expense of cleaning the property.



Amount Requested: None.                              Amount Budgeted: $0

Fund(s) or Account(s): Public Improvement            Fund(s) or Account(s): N/A

Recommended Motion: Authorize the Code Coordinator to work with the developer and complete
the sale of the City owned buildable lot as described and to have the Mayor and Clerk sign the
purchase agreement and deed.

SPECIAL EVENT POLICY

The City of Muskegon has many parks and facilities available for use. A

Submitted By: Leo Evans                                                Department of Public Works

Brief Summary:
Staff is requesting authorization to approve the Professional Services Agreement and a Contract
Amendment with Prein & Newhof related to water and sewer engineering services on a variety of
projects.

Detailed Summary & Background:
Staff has been working to pursue multiple water/sewer projects as a part of the State of Michigan
Revolving Loan programs (DWRF / SRF) during the State 2023 Fiscal Year. The projects included for
engineering within the new Professional Services Agreement are as follows and would be constructed
during 2024.

Glenside Phase 2 & 3
The first phase of this project was completed in 2020 and included work on Westwood Street. Phase 2
is focused on Hadden Street and was designed last year though the project was shelved before being
moved into construction. Phase 3 includes the remainder of the southwest portion of the Glenside
neighborhood. These projects are geared towards eliminating water/sewer utilities that are located in
non-existent alleys that are inaccessible for maintenance. These projects require a meeting with the
neighborhood to review options to fund the ineligible portions of the project which will be scheduled
later this fall or early this winter. If an amicable solution cannot be found for addressing the ineligible
pieces these projects will likely be shelved and not pursued in earnest.

Wilcox and Thompson Avenues
This project is focused on repairing two of the major sewer lines in the Bluffton area that contributed
largely towards the inflow and infiltration that our sewer system saw in 2019-2020. The work will also
replace the water lines within the roadways and see roadway reconstruction on both streets.

Morton Avenue
This project is targeted towards a water reliability issue in the Lakeside neighborhood and seeks to
improve flows in the impacted portion of the neighborhood by improving the connection between the
larger water mains in Lincoln Street and Denmark Street. The project will also address one section of
sewer that has shown signs of failure between Meuer Court and Leon Street.

Harbour Towne and Edgwater Lift Stations
These projects will be targeted towards rehabilitation and system upgrades for the existing lift stations
which are nearing end of life.

Lead Service Lines
This project will seek to contract the replacement of around 500 lead service lines in the city. A
targeted area has not yet been identified, but will be advised by the work that is currently underway to
verify and catalogue our existing service line materials throughout the city.
The project included in the amendment is a reduction to a previously approved professional services
agreement (9/14/2021) to eliminate the remaining funds in that approval which were dedicated towards
the completion of Glenside Phase 2 (Hadden Street) as those costs are now being shifted to the new
Professional Services Agreement and are incorporated above.

Portions of the engineering work required for these projects are included in the 22/23 budget and
should they all move forward the projects will continue to have allocations included in the 23/24 and
24/25 fiscal years. The projects represent an approximately $16M Investment of which the state is
prepared to award a combination of grants and principal forgiveness of around $10M, leaving
approximately $1M in cash costs due during construction (Glenside) and around $5M to be financed
through the DWRF/CWSRF loan programs for 20 years at a 1.875% interest rate. These projects are
situated to be large benefactors of the Federal/State infrastructure dollars that were allocated under
the IIJA (Infrastructure Investment and Jobs Act).

Staff has reviewed the proposal from Prein and Newhof and feels they are the best suited firm to
handle these projects based on their past experience. A qualifications for bid process was used in
2019 that shortlisted Prein & Newhof along with two other firms to provide engineering services for
these projects for the next 5-years.


Goal/Focus Area/Action Item Addressed:
Financial Infrastructure / Identify specific major capital projects across all departments

Amount Requested: $1,319,600 (TOTAL)                   Amount Budgeted: $500,000 (22/23)
$423,600 (23/24 – Prelim + Design + Bidding)

Recommended Motion:
Authorize staff to sign the professional services agreement and the professional services
agreement amendment with Prein & Newhof to provide comprehensive engineering services for
the cities fiscal year 2024 DWRF and CWSRF projects and modify the previously approved
professional services agreement.

Approvals:                                                              Guest(s) Invited / Presenting

Re:       Proposal for Professional Engineering Services for FY 23 SRF/DWRF Implementation

Dear Mr. Evans:

We appreciate this opportunity to provide a proposal for professional engineering services to assist
you with your SRF/DWRF projects for Fiscal Year 2023. This is a continuation of services for
projects outlined in your 2021 Project Plans for Water and Wastewater system improvements.

The specific projects covered under this proposal include the following:

      • Glenside Phase II – Hadden Street (Design is Complete)
      • Glenside Phase III – Winchester Drive and Montague Avenue west of Wickham

      • Wilcox and Thompson Avenues – Plum to Edgewater including Edgewater, Cherry, and
        Walnut Streets
      • Harbor Towne and Edgewater Lift Station Rehabilitations

We have reviewed the projects and have developed the following scope of services based on the
project descriptions in the SRF and DWRF Project Plans. We assume that the City will follow the 4th
quarter funding schedule, which requires project documents to be completed and ready for bidding
by spring 2023, and construction will occur through the 2024 construction season.

Design and Bidding Phase

      •   Gather and review record plans, private utility information and any available records
          pertinent to the proposed project areas;
      •   Complete topographic survey of all projects;

                 that Engineer’s opinions of costs are based on experience, judgment, and information available at a specific period of time.
                 Client agrees that Engineer makes no guarantees or warranties, express or implied, that costs will not vary from such
                 opinions.
              G. Client Responsibilities
                 1. Client shall provide all criteria, Client Standards, and full information as to the requirements necessary for Engineer to
                    provide the professional services. Client shall designate in writing a person with authority to act on Client’s behalf on all
                    matters related to the Engineer’s services. Client shall assume all responsibility for interpretation of contract documents
                    and construction observation/field observation during times when Engineer has not been contracted to provide such
                    services and shall waive any and all claims against Engineer that may be connected thereto.
                 2. In the event the project site is not owned by the Client, the Client must obtain all necessary permission for Engineer to
                    enter and conduct investigations on the project site. It is assumed that the Client possesses all necessary permits and
                    licenses required for conducting the scope of services. Access negotiations may be performed at additional costs.
                    Engineer will take reasonable precaution to minimize damage to land and structures with field equipment. Client
                    assumes responsibility for all costs associated with protection and restoration of project site to conditions existing prior to
                    Engineer’s performance of services.
                 3. The Client, on behalf of all owners of the subject project site, hereby grants permission to the Engineer to utilize a small
                    unmanned aerial system (sUAS) for purposes of aerial mapping data acquisition. The Client is responsible to provide
                    required notifications to the property owners of the subject project site and affected properties where the sUAS services
                    will be performed. The Engineer will operate the sUAS in accordance with applicable State and Federal Laws.
              H. Hazardous or Contaminated Materials/Conditions
                     1. Client will advise Engineer, in writing and prior to the commencement of its services, of all known or suspected
                        Hazardous or Contaminated Materials/Conditions present at the site.
                     2. Engineer and Client agree that the discovery of unknown or unconfirmed Hazardous or Contaminated
                        Materials/Conditions constitutes a changed condition that may require Engineer to renegotiate the scope of or terminate
                        its services. Engineer and Client also agree that the discovery of said Materials/Conditions may make it necessary for
                        Engineer to take immediate measures to protect health, safety, and welfare of those performing Engineer’s services.
                        Client agrees to compensate Engineer for any costs incident to the discovery of said Materials/Conditions.
                     3. Client acknowledges that Engineer cannot guarantee that contaminants do not exist at a project site. Similarly, a site


                                                                                                                                                             page 1 of 3
                                                                                    R:\Draft Specifications and Documents\Final P&N Agreements 2015-06-24\Standard Terms and Conditions - Public Entities.docx
(updated May 27, 2022)
                         which is in fact unaffected by contaminants at the time of Engineer’s surface or subsurface exploration may later, due to
                         natural phenomena or human intervention, become contaminated. The Client waives any claim against Engineer, and
                         agrees to defend, indemnify and hold Engineer harmless from any claims or liability for injury or loss in the event that
                         Engineer does not detect the presence of contaminants through techniques commonly employed.
                     4. The Client recognizes that although Engineer is required by the nature of the services to have an understanding of the
                        laws pertaining to environmental issues, Engineer cannot offer legal advice to the Client. Engineer urges that the Client
                        seek legal assistance from a qualified attorney when such assistance is required. Furthermore, the Client is cautioned to
                        not construe or assume that any representations made by Engineer in written or conversational settings constitute a legal
                        representation of environmental law or practice.
                     5. Unless otherwise agreed to in writing, the scope of services does not include the analysis, characterization or disposal of
                        wastes generated during investigation procedures. Should such wastes be generated during this investigation, the Client
                        will contract directly with a qualified waste hauler and disposal facility.
              I.     Underground Utilities – To the extent that the Engineer, in performing its services, may impact underground utilities,
                     Engineer shall make a reasonable effort to contact the owners of identified underground utilities that may be affected by the
                     services for which Engineer has been contracted, including contacting the appropriate underground utility locating entities
                     and reviewing utility drawings provided by others. Engineer will take reasonable precautions to avoid damage or injury to
                     underground utilities and other underground structures. Client agrees to hold Engineer harmless for any damages to below
                     ground utilities and structures not brought to Engineers attention and/or accurately shown or described on documents
                     provided to Engineer.
              J. Insurance
                     1. Engineer will maintain insurance for professional liability, general liability, worker’s compensation, auto liability, and
                        property damage in the amounts deemed appropriate by Engineer. Client will maintain insurance for general liability,
                        worker’s compensation, auto liability, and property damage in the amounts deemed appropriate by Client. Upon request,
                        Client and Engineer shall each deliver certificates of insurance to the other evidencing their coverages.
                     2. Client shall require Contractors to purchase and maintain commercial general liability insurance and other insurance as
                        specified in project contract documents. Client shall cause Engineer, Engineer’s consultants, employees, and agents to be
                        listed as additional insureds with respect to any Client or Contractor insurances related to projects for which Engineer
                        provides services. Client agrees and must have Contractors agree to have their insurers endorse these policies to reflect
                        that, in the event of payment of any loss or damages, subrogation rights under these Terms and Conditions are hereby
                        waived by the insurer with respect to claims against Engineer.
              K. Limitation of Liability - The total liability, in the aggregate, of Engineer and Engineer’s officers, directors, partners,
                 employees, agents, and consultants, whether jointly, severally or individually, to Client and anyone claiming by, through, or
                 under Client, for any and all injuries, losses, damages and expenses, whatsoever, arising out of, resulting from, or in any
                 way related to the Project or the Agreement, including but not limited to the performance of services under the Agreement,
                 from any cause or causes whatsoever, including but not limited to the negligence, professional errors or omissions, strict
                 liability or breach of contract or warranty, expressed or implied, of Engineer or Engineer’s officers, directors, partners,
                 employees, agents, consultants, or any of them, shall not exceed the amount of the compensation paid to Engineer under this
                 Agreement, or the sum of fifty thousand dollars and no cents ($50,000.00), whichever is less. Recoverable damages shall be
                 limited to those that are direct damages. Engineer shall not be responsible for or held liable for special, indirect or
                 consequential losses or damages, including but not limited to loss of use of equipment or facility, and loss of profits or
                 revenue.
                     Client acknowledges that Engineer is a corporation and agrees that any claim made by Client arising out of any act or
                     omission of any director, officer, or employee of Engineer, in the execution or performance of the Agreement, shall be made
                     against Engineer and not against such director, officer, or employee.
              L. Documents and Data
                     1. All documents prepared or furnished by Engineer under the Agreement are Engineer’s instruments of service, and are
                        and shall remain the property of Engineer.
                     2. Hard copies of any documents provided by Engineer shall control over documents furnished in electronic format. Client
                        recognizes that data provided in electronic format can be corrupted or modified by the Client or others, unintentionally or
                        otherwise. Consequently, the use of any data, conclusions or information obtained or derived from electronic media
                        provided by Engineer will be at the Client’s sole risk and without any liability, risk or legal exposure to Engineer, its
                        employees, officers or consultants.
                     3. Any extrapolations, conclusions or assumptions derived by the Client or others from the data provided to the Client,
                        either in hard copy or electronic format, will be at the Client’s sole risk and full legal responsibility.


                                                                                                                                                              page 2 of 3
                                                                                     R:\Draft Specifications and Documents\Final P&N Agreements 2015-06-24\Standard Terms and Conditions - Public Entities.docx
(updated May 27, 2022)
              M. Differing Site Conditions - Client recognizes that actual site conditions may vary from the assumed site conditions or test
                 locations used by Engineer as the basis of its design. Consequently, Engineer does not guarantee or warrant that actual site
                 conditions will not vary from those used as the basis of Engineer’s design, interpretations and recommendations. Engineer is
                 not responsible for any costs or delays attributable to differing site conditions. .
              N. Terms of Payment - Unless alternate terms are included in the Agreement, Client will be invoiced on a monthly basis until
                 the completion of the Project. All monthly invoices are payable within 30 days of the date of the invoice. Should full
                 payment of any invoice not be received within 30 days, the amount due shall bear a service charge of 1.5 percent per month
                 or 18 percent per year plus the cost of collection, including reasonable attorney’s fees. If Client has any objections to any
                 invoice submitted by Engineer, Client must so advise Engineer in writing within fourteen (14) days of receipt of the invoice.
                 Unless otherwise agreed, Engineer shall invoice Client based on hourly billing rates and direct costs current at the time of
                 service performance. Outside costs such as, but not limited to, equipment, meals, lodging, fees, and subconsultants shall be
                 actual costs plus 10 percent. In addition to any other remedies Engineer may have, Engineer shall have the absolute right to
                 cease performing any services in the event payment has not been made on a current basis.
              O. Termination - Either party may terminate services, either in part or in whole, by providing 10 calendar days written notice
                 thereof to the other party. In such an event, Client shall pay Engineer for all services performed prior to receipt of such
                 notice of termination, including reimbursable expenses, and for any shut–down costs incurred. Shut–down costs may, at
                 Engineer’s discretion, include expenses incurred for completion of analysis and records necessary to document Engineer’s
                 files and to protect its professional reputation.
              P. Severability and Waiver of Provisions - Any provision or part of the Agreement held to be void or unenforceable under
                 any laws or regulations shall be deemed stricken, and all remaining provisions shall continue to be valid and binding upon
                 Client and P&N, who agree that the Agreement shall be reformed to replace such stricken provision or part thereof with a
                 valid and enforceable provision that comes as close as possible to expressing the intention of the stricken provision. Non-
                 enforcement of any provision by either party shall not constitute a waiver of that provision, nor shall it affect the
                 enforceability of that provision or of the remainder of the Agreement.
              Q. Dispute Resolution - If a dispute arises between the parties relating to the Agreement, the parties agree to use the following
                 procedure prior to either party pursuing other available remedies:
                     1. Prior to commencing a lawsuit, the parties must attempt mediation to resolve any dispute. The parties will jointly appoint
                        a mutually acceptable person not affiliated with either of the parties to act as mediator. If the parties are unable to agree
                        on the mediator within twenty (20) calendar days, they shall seek assistance in such regard from the Circuit Court of the
                        State and County wherein the Project is located, who shall appoint a mediator. Each party shall be responsible for paying
                        all costs and expenses incurred by it, but shall split equally the fees and expenses of the mediator. The mediation shall
                        proceed in accordance with the procedures established by the mediator.
                     2. The parties shall pursue mediation in good faith and in a timely manner. In the event the mediation does not result in
                        resolution of the dispute within thirty (30) calendar days, then, upon seven (7) calendar days’ written notice to the other
                        party, either party may pursue any other available remedy.
                     3. In the event of any litigation arising from the Agreement, including without limitation any action to enforce or interpret
                        any terms or conditions or performance of services under the Agreement, Engineer and Client agree that such action will
                        be brought in the District or Circuit Court for the County of Kent, State of Michigan (or, if the federal courts have
                        exclusive jurisdiction over the subject matter of the dispute, in the U.S. District Court for the Western District of
                        Michigan), and the parties hereby submit to the exclusive jurisdiction of said court.
              R. Force Majeure - Engineer shall not be liable for any loss or damage due to failure or delay in rendering any services called
                 for under the Agreement resulting from any cause beyond Engineer’s reasonable control.
              S. Assignment - Neither party shall assign its rights, interests or obligations under this Agreement without the express written
                 consent of the other party.
              T. Modification - The Agreement may not be modified except in writing signed by the party against whom a modification is
                 sought to be enforced.
              U. Survival - All express representations, indemnifications, or limitations of liability included in the Agreement shall survive
                 its completion or termination for any reason.
              V. Third-Party Beneficiary - Client and Engineer agree that it is not intended that any provision of this Agreement establishes
                 a third-party beneficiary giving or allowing any claim or right of action whatsoever by a third party.
              W. Fee Escalation - Proposed fees include a three percent (3%) per year cost of living adjustment. Should CPI increase by
                 more than 3% in a year, Engineer reserves the right to adjust fees at the beginning of the following year by the amount of
                 the prior year CPI increase.

    2207B (05/21)                   PERFORMANCE RESOLUTION FOR
                                          MUNICIPALITIES

 This Performance Resolution (Resolution) is required by the Michigan Department of Transportation for
 purposes of issuing to a Municipality an ''Individual Permit for Use of State Highway Right of Way'', and/or
 an ''Annual Application and Permit for Miscellaneous Operations within State Highway Right of Way''.

RESOLVED WHEREAS, the
                                                     (County, City, Village, Township, etc.)
hereinafter referred to as the ''MUNICIPALITY,'' periodically applies to the Michigan Department of
Transportation, hereinafter referred to as the "DEPARTMENT," for permits, referred to as ''PERMIT,'' to
construct, operate, use and/or maintain utilities or other facilities, or to conduct other activities, on, over, and
under State Highway Right of Way at various locations within and adjacent to its corporate limits;

NOW THEREFORE, in consideration of the DEPARTMENT granting such PERMIT, the MUNICIPALITY
agrees that:
 1. Each party to this R e s o lu t io n shall remain responsible for any claims arising out of their own acts and/or
    omissions during the performance of this R e s o lu tio n , as provided by law. This R e s o l u t io n is not
    intended to increase either party's liability for, or immunity from, tort claims, nor shall it be interpreted,
    as giving either party hereto a right of indemnification, either by Agreement or at law, for claims arising
    out of the performance of this Agreement.

 2. If any of the work performed for the MUNICIPALITY is performed by a contractor, the MUNICIPALITY shall
    require its contractor to hold harmless, indemnify and defend in litigation, the State of Michigan, the
    DEPARTMENT and their agents and employee’s, against any claims for damages to public or private
    property and for injuries to person arising out of the performance of the work, except for claims that result
    from the sole negligence or willful acts of the DEPARTMENT, until the contractor achieves final acceptance
    of the MUNICIPALITY Failure of the MUNICIPALITY to require its contractor to indemnify the
    DEPARTMENT, as set forth above, shall be considered a breach of its duties to the DEPARTMENT.

 3. Any work performed for the MUNICIPALITY by a contractor or subcontractor will be solely as a contractor
    for the MUNICIPALITY and not as a contractor or agent of the DEPARTMENT. The DEPARTMENT shall
    not be subject to any obligations or liabilities by vendors and contractors of the MUNICIPALITY, or their
    subcontractors or any other person not a party to the PERMIT without the DEPARTMENT’S specific prior
    written consent and notwithstanding the issuance of the PERMIT. Any claims by any contractor or
    subcontractor will be the sole responsibility of the MUNICIPALITY.

 4. The MUNICIPALITY shall take no unlawful action or conduct, which arises either directly or indirectly out
    of its obligations, responsibilities, and duties under the PERMIT which results in claims being asserted
    against or judgment being imposed against the State of Michigan, the Michigan Transportation Commission,
    the DEPARTMENT, and all officers, agents and employees thereof and those contracting governmental
    bodies performing permit activities for the DEPARTMENT and all officers, agents, and employees
    thereof, pursuant to a maintenance contract. In the event that the same occurs, for the purposes of the
    PERMIT, it will be considered as a breach of the PERMIT thereby giving the State of Michigan, the
    DEPARTMENT, and/or the Michigan Transportation Commission a right to seek and obtain any necessary
    relief or remedy, including, but not by way of limitation, a judgment for money damages.

 5. The MUNICIPALITY will, by its own volition and/or request by the DEPARTMENT, promptly restore and/or
    correct physical or operating damages to any State Highway R ight of Way resulting from the
    installation construction, operation and/or maintenance of the MUNICIPALITY’S facilities according to a
    PERMIT issued by the DEPARTMENT.

6.    With respect to any activities authorized by a PERMIT, when the MUNICIPALITY requires insurance on
      its own or its contractor's behalf it shall also require that such policy include as named insured the State
      of Michigan, the Transportation Commission, the DEPARTMENT, and all officers, agents, and employees
      thereof and those governmental bodies performing permit activities for the DEPARTMENT and all
      officers, agents, and employees thereof, pursuant to a maintenance contract.

7.    The incorporation by the DEPARTMENT of this Resolution as part of a PERMIT does not prevent the
      DEPARTMENT from requiring additional performance security or insurance before issuance of a
      PERMIT.

8.    This Resolution shall continue in force from this date until cancelled by the MUNICIPALITY or the
      DEPARTMENT with no less than thirty (30) days prior written notice provided to the other party. It
      will not be cancelled or otherwise terminated by the MUNICIPALITY with regard to any PERMIT which has
      already been issued or activity which has already been undertaken.

 BE IT FURTHER RESOLVED that the following position(s) are authorized to apply to the DEPARTMENT for
 the necessary permit to work within State Highway Right of Way on behalf of the MUNICIPALITY.

Submitted By: Leo Evans                                              Department of Public Works

Brief Summary:
Staff is requesting authorization to accept the Skate Park proposal submitted by Grindline Skateparks,
Inc.

Detailed Summary & Background:
Staff solicited proposals for firms to assist in Phase 1 (Conceptual Design) and Phase 2 (Financing) for
the development of a new skate park in the City located primarily within Rotary Park adjacent to the
Boys and Girls Club. A copy of the request for qualifications is attached.

Five proposals were received and scored by a team of three (Matt Schwemin – City Parks Supervisor,
Steve Fink – County DPW/Facilities Engineer, and Don Steigman – Local Skate Park Advocate).
Additional seats on the review team were offered to the Boys and Girls Club and Rotary, they both
declined to participate in the selection, but wished to remain actively involved and engaged in the
development of the project. After independent scoring and rigorous group discussion Grindline
Skateparks was determined to be the firm providing the best proposal for this project. Scoresheets are
attached showing the average score for each proposal in each category. Grindline also received an
excellent reference from the City of Detroit in regards to the Riverside Skate Park built in 2019.

A copy of the proposal submitted by Grindline Skateparks is included for reference with this
commission packet.

We are roughly 2 weeks behind where we had hoped to be at this stage as it took longer than
anticipated to complete the scoring and reference checks but we should still be in a good position to
host an initial kickoff meeting in November.

Design Services for a Skatepark in The City of Muskegon, MI.

Dear Mr. Evans,

Grindline Skateparks appreciates the opportunity to submit a proposal to the City of Muskegon for design services of a
skatepark located at 900 West Western Avenue Muskegon, MI 49441. Grindline was incorporated in Washington State on
April 8, 2002 and has since been evolving the art and science of skateparks with a track record of over 300 successful
Skatepark design and construction projects nationally and internationally on our resume. When it comes to skatepark
specialists, our ability to translate the needs of a community into a new landscape of skateboard terrain is unrivaled by
any other company in the world. Grindline can complete all skatepark speci�c design services including Site Analysis,
Community Outreach, Conceptual Design, Cost Estimating, an��       nal Construction Documents.

Grindline will manage this project as the Prime Design Consultant to provide a single point of contact throughout the
life of this project and we will leverage our existing relationship with ROWE Professional Services Company to provide
Civil Engineering, for the project. ROWE’s local staff has the necessary skills and quali�cations required to support and
compliment Grindline in providing a successful project for the Township. ROWE is currently working with Grindline on
similar projects in Port Huron. Pontiac, and Flint, MI.

It is our understanding that the City of Muskegon proposes to design and construct a "state of the art" park utilizing the
latest skate park design principles and construction with high quality materials to ensure durability and longevity. The
skatepark shall answer to the community and City’s needs and typically include a mix of street-scape type and transitional
style elements to accommodate primarily skateboarders, scooters, and BMX riders. It should be designed to develop and
expand a variety of experience and skills, and encourage progressive skill building at all levels. The size of the skatepark
is currently planned to be designed around approximately 10,000 square feet. The design shall not only be focused on
the functionality, but also engage with the surrounding area and blend into the area with a cohesive sense of place. We
understand that during the design phase, the Boys and Girls Club property can afford to lose no more than 8 parking
spaces, and should allow for ample room for a driveway or road to be built alongside the east side of the Boys and Girls
club building. The design should also include two sidewalks that connect from the Boys and Girls Club parking lot and the
Rotary Park. We also are aware that the pine trees on the proposed site should be preserved. There should also be a fence
and no features constructed on top of the storm water sewer outfall in the event of needed maintenance.

Within our submission, you will �nd information about our team, previous project experience, and our design methodology.
Our combination of world class skatepark design and knowledge make our team the best �t for your project. Collectively,
we are enthusiastic about this project and the prospect of developing a skatepark that will meet the needs of the City and
serve as an active recreation destination for the youth and families of the community.

As the CEO of Grindline Skateparks, I am authorized to represent the�rm in any negotiations and sign any legally binding
contracts for this project.

Sincerely,




Matt Fluegge

     FIRM QUALIFICATIONS


Our Company
GRINDLINE SKATEPARKS INC.

Since 2002, the Grindline team has designed, sculpted, and skated millions of tons of concrete across the United States and
around the World. Grindline has developed the full spectrum of skate terrain including street courses, bowl complexes, snake
runs, pump tracks, hobbit trails, professional training facilities, skateable sculptures and all those features yet to be named.
We translate the needs of local skaters into skatepark designs that will progress with them into the future. Our parks range in
size from the largest skatepark in North America all the way down to a single skate obstacle. Regardless of square footage,
skaters are riding our parks from dawn to dusk. We have designed and constructed over 300 skateparks to date, from Orcas
Island in Washington State to the Holy Lands of Israel, giving us an intimate understanding of building community through
skateboarding.

Grindline has extensive knowledge and experience with skatepark design and construction in climates similar to Troy. Similar
to other Grindline projects, we will implement speci�c design and construction techniques to prevent frost heaving or damage
from freeze thaw cycles such as air entrained concrete, low slump, minimal water to cement ratio in the concrete mix design
and footings placed below frost lines. We recommend the majority of concrete placement during the spring through early fall
months to avoid concrete placement in cold weather. We recommend the majority of concrete placement during the summer or
early fall months to avoid concrete placement in cold weather. If the schedule does dictate pouring concrete in winter months,
we are well versed in cold weather concreting (ACI 306.1) and follow all guidelines set forth by the American Concrete Institute,
including but not limited to, taking appropriate measures to thaw sub-grade prior to placement, hot water concrete batching,
not non- chloride accelerator, insulated concrete blankets during cure, and tenting and heating during the �   nishing process.
Note - cold weather/hot weather concreting can impact costs signi�   cantly, and should be a consideration when developing the
overall schedule and budget for the project.

As a contractor specializing in concrete construction, we are highly aware of the effects from the growing amount of hardscape
on the environment. On every job, Grindline incorporates green construction techniques such as:

•	       Recycled concrete for sub base materials
•	       Fly-ash in our concrete and shotcrete mixes
•	       On-site stormwater management
•	       Recycling of construction materials such as formwork and site spoils

Grindline has the appropriate � nancial and staf� ng resources to undertake a project of this scope and size. It is the normal

A successful skatepark is the result of an entire community coming together to work toward a common purpose. It’s our respon-
sibility to engage all interest groups throughout the development of their park and motivate them to work together. We aim to
empower skate advocates and community groups by giving them the tools and knowledge they need to make informed decisions
about their park. The development process relies on a commitment to collaboration and communication amongst stakeholders.
We facilitate the exchange of ideas and information related to aesthetics, safety, crime prevention, as well as programming, and
meld these “needs” and “wants” into a successful skatepark. Our principal design philosophy is based on our recognition that
every community and project site is unique, requiring a skatepark design tailored to its location. To do so, our approach is based
on four fundamentals:

    •	     Open collaboration with the client and community through community involvement & public outreach
    •	     Timeless Designs that appeal to all ages and skill levels
    •	     Integration & Context
    •	     Ef�cient Engineering, Sustainable Design and Budget Management


DESIGNING FOR DIFFERENT SKILL LEVELS

Grindline’s designs offer a Ladder of Progression for skaters to incrementally develop their skills and advance their sport.
The skatepark is more than a sum of all its individual elements, it is the overall experience of the park that brings end users
back—day after day, week after week.

Our Ability to Problem Solve
Just like every Grindline Skatepark, each designated project site is unique. Each distinctive construction site seems to come
with at least one problem, sometimes completely unique to anything we have seen before. At Grindline we strive to identify
these problems early in the design process, and turn them into opportunities to manifest, design, plan, and ����    implement
innovative solutions. The following list are just few examples of the problems we have come across, and the innovate
solutions we have executed to mitigate them.

Scope of Work
Project Understanding - Based off the information provided by the City in the RFP, our current understanding of the project is
as follows:

•	    Conceptual Design – Includes participation in a kick-off meeting with the designated group of stakeholders to review the
      proposed location, establish the target size of the park (+/- 10,000 SFT), and identify the potential elements. Upon completion
      of the kick-off meeting the selecte��   rm shall create preliminary site renderings and cost estimates.
•	    Community Outreach – Includes presenting the conceptual design material and cost estimates in a community meeting
      format and soliciting feedback from the wider public, possibly through a survey.
•	    Concept Revision - Includes re�    nement of the conceptual designs and preparation of �     nal renderings and cost estimates
      for the selected alternative. Cost estimates should be all inclusive of construction costs, engineering fees, permit fees,
      future maintenance costs, etc… The goal is to ensure that fundraising efforts successfully cover all necessary costs for
      construction and perpetual care.
•	    Concept Finalization – Includes hosting a second community meeting to present th��         nal design details.
•	    Detailed Design – Upon identi�     cation of an appropriate fundraising mechanism for the project, the selected vendor will
      be directed to complete a detailed design for the site including all appropriate survey, plans, speci�    cations, and complete
      contract documents for bidding.
•	    Bid Solicitation – Vendor shall assist the city in obtaining bids for the entire project, and/or for any individual components
      of the project that are not directly performed by the selected vendor. The city’s preference is to hire a vendor that can
      design and construct the skate park. City purchasing policy guidelines shall be followed for any items sent for bidding, and
      any vendors involved in the construction phase shall be required to comply with all standard City policies and procedures
      regarding contracting.
•	    The Boys and Girls Club property can afford to lose no more than 8 parking spaces as a result of this project.
•	    The design should allow ample room for a driveway/road to be constructed along the east side of the Boys and Girls Club
      building in the future if/when that is ever needed.
•	    The design should include two (2) sidewalk connections between the Boys and Girls Club parking lot and Rotary Park. Two
      (2) connections exist currently; they can be maintained in their existing state, or rerouted as a part of the design.
•	    The mature pine trees on the south end of the identi�   ed area should be preserved if possible with a preference to incorporate
      them into the design.
•	    The skate park should include fencing along the perimeter where necessary to comply with standard practices. Appropriate
      separation and access should be maintained between the existing playground features and the proposed skate park.
•	    There should be no primary features constructed on top of the storm sewer outfall in the event it requires future maintenance.
      Consideration could be given to potentially removing the enclosed storm sewer outlet and incorporating an open channel for
      the outlet into the design of the park.

Scheduling - Each of our Project Managers have completed formal educational training, receiving post graduate certi�        cates
from University of Washington Project Management Program. We are well versed in Critical Path Method (or CPM) scheduling
for both design and construction, and will tailor our customized CPM Master Schedule Template to your project speci�        cally.
Through close communication with the Project Team we will develop a list of appropriate tasks throughout the lifecycle of project,
while identifying key deliverables and milestones within each of the project phases. Our experience with Microsoft Project
software allows us to revise schedules on the � y if needed and communicate that information back to the project team. During
construction each of our foreman is equipped with mobile daily reporting software which allows our PM’s to get information that
may impact schedule and/or budget from the �   eld immediately so that we can alert the Owner’s Representative and determine
the best course of action.

Budget Control - With Grindline’s vast experience in Skatepark projects, we understand the unique set of challenges that
accompany the design/build approach. Here at Grindline we see the Design/Build approach as an opportunity to maximize
a project budget through the following:

1.	 Preliminary organized framework that is easy for all parties to understand and decipher.
2.	 Complete budget transparency through design and construction.
3.	 Treating the budget as a living document where changes can be easily tracked and traced.
4.	 Engaging all stakeholders to prioritize the project elements and maintain sort of a project “menu” based on those
    priorities.
5.	 Organized accounting and project tracking throughout in order to provide backup upon request for any project costs
    incurred.



                                                                                                                                   13
     SCOPE OF WORK


A revised budget document will be prepared and submitted at every design submittal phase throughout the design process.
For use of preliminary estimating, we maintain a signi�   cant data base of past bids and proposals from the last 18 years and are
constantly updating material and labor costs in the areas we work in. Grindline works on a nationwide basis with both public and
private projects and we continually document budget trends to assist clients in developing realistic budgets. As we move through
the project we will constantly value engineer the project to maximize your budget. As the design develops, we will reach out to
and solicit local subcontractors for hard costs in order to lock in a project program based on the re�ned budget document.

If the projected costs are signi�cantly below budget levels, we will present and discuss possible project scope expansions
to take advantage of project scale in lowering unit costs. Should the projected costs exceed the budget, we will revisit the
design elements, materials and methods to determine where changes can be made without sacri�cing important project
goals. In both cases, the �nal decisions on scope increases or reductions remains with the Township, and in both cases,
the project would not intentionally move forward without a resolution to the issue.

Progress Reports and Required Meetings – We have provided review/coordination meetings in our scope of work at important
milestones but the interval and timing of actual Progress Review Meeting will be determined at the Project Kick-off meeting. Prior
to each Progress Review Meeting, the Design Team will submit an updated schedule and all completed or partially completed
plans, speci�
            cations and estimates which have been developed or altered since the last Progress Review Meeting

PHASE 1A: PROJECT STARTUP

i. Obtain site information: Grindline will review existing site information and determine what additional information is
required to complete the design. We will schedule and acquire an Existing conditions Survey for the skatepark site.

ii. Project Kick Off Meeting: Grindline will meet virtually with the City committee and any other key stakeholders to
discuss and �nalize project objectives including scope, schedule and budget. A communication plan will be made to identify
preferred communication methods. Key meetings and deliverables will be scheduled and areas requiring coordination such
as public meetings, online forums and exchange/review of documents will be identi�ed. The discussion will identify any
outstanding issues with the project, and propose solutions for any issues identi�ed.

iii. Site Analysis: Grindline and the Project Team will perform a Site Analysis to review the existing conditions, explore
opportunities and constraints of the site, evaluate and review current usage of existing skatepark, adjacent park facilities, and
programming spaces to assist in design development.

     Existing Site Conditions - The proposed site area for the skatepark is on a �  at area adjacent to the lake. These will factor
     into how drainage is planned heavily. The area also has two intersecting walking paths, meaning implimenting elements
     of CPTED will be feasible. The site has a handful of trees but besides this is grass meaning a minimal impact on natural
     vegitaion will happen when adding the skatepark. Stormwater will be directed to a bioretention and in� ltration area designed
     to accommodate the required storm events. Only areas that need to be cleared for construction will be cleared minimizing
     the impact the existing natural vegetation.

     Current and Planned Improvements - The skatepark must integrate with existing and future adjacencies at the
     Recreations. Restrooms, walkways, connection paths, park seating, non-skatepark play areas, and parking all play
     roles in the skatepark placement on site. We will look at the siting of current skatepark as well as connections to and
     from the skatepark.

     External Circulation & Public Safety - We look at how users get to the skatepark, whether by car, board, bike, foot,
     public transportation, and determine if any improvements need to be included in the current and future phases of the
     project to allow safe access to the skatepark. And, as in any park where younger citizens will gather, we put CPTED
     principles into practice to discourage or impede criminal behavior and, at the same time, encourage honest citizens to
     keep a watchful eye.

     Internal Circulation - Proper placement of amenities, traf�c patterns, and circulation through the park are reviewed.
     We scrutinize the location and placement of the proposed skate features to create smooth �ow through the skatepark
     and avoid potential collision routes or blind spots. We identify safe paths for spectators in the skatepark by properly
     locating entrances to the facility and including passive zones for viewing or resting areas.

                      PHASE 1B & 2: CONCEPTUAL DESIGN

                      Skate parks are more than athletic facilities. They are gathering places and can be focal points for other activities like
                      concerts, competitions or community events. Facilities must be designed to meet skating demands, incorporate areas
                      for spectators, and to appropriately blend with their existing surroundings. Through the use of custom materials and the
                      placement of green space in and around the design, the skatepark ties into the overall form and function of its setting.
                      Conceptual Designs illustrate our skatepark philosophy to key stakeholders and the community in interactive, full color
                      presentations of the custom skate features and facilities included in the project. 3D models allow us to clearly and effectively
                      communicate our skatepark concepts to the client and community as well as assist in the development of accurate cost
                      estimates and material take-offs. The result is a design produced from the ideas and recommendations of ALL stakeholders
                      involved with the project.

PROGRAMMING, OPERATIONS & MAINTENANCE

At Grindline our motto is "Grindline for Life". When you hire Grindline we embrace your community and are with you long
after the Grand Opening. While a Grindline skatepark is a self-suf�cient venue for year-round recreation, planning and
care will add to the success of the project. Grindline has done numerous projects with multiple phases (such as Hideaway
Park in Winter Park) and we provide maintenance plans to enhance the lifespan of your skatepark. Grindline has valuable
relationships with organizations such as Skate Like a Girl, United States Skateboarding Education Association, and the
Stronghold Society who collectively advocate for skateboarding and host programs to give local youth access to the sport.
Programs such as skate lessons, skate camps, contests and demonstrations provide opportunities to further support the
skateboarding community.

Our collective experience in the �eld of skatepark design and construction also gives us the knowledge to assess skateparks
in terms of physical condition and carry out maintenance and repair actions to extend the life of a skatepark. On aging
skateparks, we can evaluate the current function and condition of the skatepark, provide cost of repairs, and create a service
plan for ongoing maintenance and/or repair.

                           SPECIFIC PROJECT INFORMATION


INTRODUCTION TO PROJECT

The City of Muskegon is seeking proposals from qualified full-service firms to assist in the
design and construction of a new skate park within the City of Muskegon. The City of
Muskegon previously had a skate park which has become obsolete and is essentially fully
abandoned. Some work has been done by the City and Stakeholders to kick start the campaign
for construction of a new park, the information compiled to date is available here:

https://www.muskegon-mi.gov/skate-park-project/

The location of the proposed skate park has been identified and is included in Attachment A.

The proposed work will be broken into phases as follows:

Phase 1 – Conceptual Design

   •   Conceptual Design – Includes participation in a kick-off meeting with the designated
       group of stakeholders to review the proposed location, establish the target size of the park
       (+/- 10,000 SFT), and identify the potential elements. Upon completion of the kick-off
       meeting the selected firm shall create preliminary site renderings and cost estimates.

   •   Community Outreach – Includes presenting the conceptual design material and cost
       estimates in a community meeting format and soliciting feedback from the wider public,
       possibly through a survey.

   •   Concept Revision - Includes refinement of the conceptual designs and preparation of final
       renderings and cost estimates for the selected alternative. Cost estimates should be all
       inclusive of construction costs, engineering fees, permit fees, future maintenance costs,
       etc… The goal is to ensure that fundraising efforts successfully cover all necessary costs
       for construction and perpetual care.

   •   Concept Finalization – Includes hosting a second community meeting to present the final
       design details.

Phase 2 - Financing

   •   Fundraising – This phase is to be completed primarily by City staff and the various
       project stakeholders, with some amount of minimal clarification and expertise required
       from the selected vendor. City Staff and stakeholders will utilize the final renderings and
       cost estimates to identify the grant funding, private fundraising, and public financing
       options available to complete construction and start a maintenance fund for the proposed
       skate park.



                                                6
Phase 3 – Detailed Design & Bidding

   •   Detailed Design – Upon identification of an appropriate fundraising mechanism for the
       project, the selected vendor will be directed to complete a detailed design for the site
       including all appropriate survey, plans, specifications, and complete contract documents
       for bidding.

   •   Bid Solicitation – Vendor shall assist the city in obtaining bids for the entire project,
       and/or for any individual components of the project that are not directly performed by the
       selected vendor. The city’s preference is to hire a vendor that can design and construct
       the skate park. City purchasing policy guidelines shall be followed for any items sent for
       bidding, and any vendors involved in the construction phase shall be required to comply
       with all standard City policies and procedures regarding contracting.

Phase 4 – Construction

   •   Construction Oversight and Project Management – Selected vendor will be responsible to
       provide management of the construction project from inception through final completion.
       Work will include addressing any requests for information, ensuring the project remains
       on schedule, maintaining the project budget, and preparing detailed As-Built drawings
       upon completion of the project.

Special Considerations

   •   The Boys and Girls Club property can afford to lose no more than 8 parking spaces as a
       result of this project.

   •   The design should allow ample room for a driveway/road to be constructed along the east
       side of the Boys and Girls Club building in the future if/when that is ever needed.

   •   The design should include two (2) sidewalk connections between the Boys and Girls
       Club parking lot and Rotary Park. Two (2) connections exist currently; they can be
       maintained in their existing state, or rerouted as a part of the design.

   •   The mature pine trees on the south end of the identified area should be preserved if
       possible with a preference to incorporate them into the design.

   •   The skate park should include fencing along the perimeter where necessary to comply
       with standard practices. Appropriate separation and access should be maintained
       between the existing playground features and the proposed skate park.

   •   There should be no primary features constructed on top of the storm sewer outfall in the
       event it requires future maintenance. Consideration could be given to potentially
       removing the enclosed storm sewer outlet and incorporating an open channel for the
       outlet into the design of the park.



                                                7
At this time the City has committed an amount of $10,000 to be allocated to the selected vendor
for completion of Phases 1 and 2 of the project. Commitments for the later Phases of the project
will be subject to a successful fundraising campaign in Phase 2.

A proposed schedule for the project is included later in this RFP.

Questions on the above phasing can be submitted to Leo Evans via email
(Leo.Evans@shorelinecity.com). Questions received prior to Monday, September 12th, 2022
will receive a response prior to the acceptance of the RFP. Requests received after that date will
receive a response pending staff availability.

Brief Summary: The Water Filtration Plant’s Source Water Intake Protection Plan is due for an
update, and the City has been awarded an EGLE grant to cover half of the project’s total cost.

Detailed Summary & Background:
City staff worked with Tetra Tech in 2017 to develop Muskegon’s first Source Water Intake
Protection Plan (SWIPP). This document is due to be updated as EGLE recommends updates
every 6 years.
The purpose of a SWIPP is to protect the long-term viability of a drinking water supply by reducing
the potential risk of surface and subsurface contamination from affecting the source water
protection area. The project will culminate with an updated SWIPP that will focus on protecting our
drinking water source, form a basis for informed decision-making regarding land use within the
community, form a basis for dealing with future regulations, and produce an approvable report with
all required elements.
Staff requested Tetra Tech provide the City with a proposal to update the plan. Tetra Tech has
extensive experience from its creation of the original plan, and the City will be working with some
of the same integral staff that created the original plan. Tetra Tech has already worked alongside
City staff on a successful grant application for this project.
This project is budgeted for $30,000 in FY 2022-23, and the grant the City was awarded from
EGLE will reimburse $15,000 of project-related expenses.

Re: Surface Water Intake Protection Plan Proposal

Dear Mr. Buthker:

The approximately 80,000 customers you serve expect the Muskegon water filtration plant to not only provide potable
water, but also be economical in the process. In this time of shrinking governmental financial support and difficult local
economic times, your water treatment process should give you the best value for each dollar, and the best way to do that is
to ensure that your source water is as free from contaminants as is practicable.

Thank you for the opportunity to provide this proposal to assist you with creating the Surface Water Intake Protection Plan
for the City of Muskegon based on your EGLE Grant requirements. We are confident that Tetra Tech offers unsurpassed
value with our water resource planning and assessment services. Attachment A details our proposed scope of services to

Source Water Intake Protection Plan
Scope of Work
September 28, 2022

INTRODUCTION
Tetra Tech understands the goal of the City of Muskegon Water Filtration Plant management is to
produce abundant, clean, safe, and aesthetically pleasing water for its customers. To effectively and
efficiently do so, it is imperative that the source water being withdrawn is of the highest quality feasible
before it is treated, polished, and eventually distributed.
Tetra Tech completed a SWIPP for the Muskegon Filtration Plant in 2017 and enlists the expertise of
some of the same integral staff to update that plan. Tetra Tech will provide a team of water resource and
land use management experts that will work with you to identify both real and potential threats to the
area source water supply. The intent is to produce a plan that contains policies, procedures, and action
items designed to ensure the safety of your water supply, now and in the future.
BACKGROUND

The Muskegon Water Filtration Plant is a conventional water treatment plant with a capacity of 40 million
gallons per day. Customers include not only the City of Muskegon, but also North Muskegon, Muskegon
Township, Roosevelt Park, County Northside, Fruitport, and Norton Shores. Water is withdrawn from
Lake Michigan.
Michigan Department of Environmental Quality (MDEQ) performed an assessment of the City’s source
water in 2003 to determine the susceptibility to or the relative potential of contamination. The
susceptibility rating is on a six-tiered scale from very low to high and is based primarily on geologic
sensitivity, water chemistry, and contaminant sources. The susceptibility of the source water is
moderately high. MDEQ was rebranded as Department of Environment, Great Lakes, and Energy
(EGLE) but the acronyms are still used interchangeably in guidance documents.
Tetra Tech completed a SWIPP for the Muskegon Water Filtration Plant in December 2017. Muskegon
has received a grant to update the SWIPP. The following activities will provide an update to that plan by
or before the end of the grant period: August 30, 2023.

DESCRIPTION OF APPROACH AND SCOPE OF SERVICES
Tetra Tech anticipates the following as goals of the Surface Water Intake Protection Plan (SWIPP):
       To focus limited resources to protect the drinking water source(s). The SWIPP will provide your
        community with recommendations for actions within the source water area (SWA) that potentially
        can directly affect your water supply. It is within this SWA that a spill or improper use of potential
        contaminants may cause these contaminants to migrate toward the water intake. By addressing where
        the source waters are most susceptible to contaminants, and where potential contaminants are located,
        the SWIPP will clearly identify the potential risks and actions that should be undertaken to mitigate
        the introduction of contaminants.
       To form the basis for informed decision-making regarding land use within the community.
        Recommendations in the SWIPP will guide the City planning authorities to make informed decisions
        regarding proposed land uses within the SWA that are compatible with both your drinking water
        resource and the vision of growth embraced by the city and neighboring communities.
       To form the basis for dealing with future regulations. The SWIPP will be designed to functionally
        meet proposed requirements for your surface-water supply. Actions needed to address the City’s
        needs and requirements will be made through this report.


Tetra Tech                                                                                         Page 1 of 5
        To produce an approvable report with all seven required elements including: Defining
         responsible agency roles, designating a source water protection area (completed by MDEQ in 2003
         assessment), contingency plans, the updated contaminant sources, alternate sources, new sources,
         and a public education plan.

The following proposed scope of work reflects Tetra Tech’s understanding of the EGLE requirements.

TASK 1: DEVELOP A SURFACE WATER INTAKE PROTECTION PLAN (SWIPP)

1.1: Document Review and Planning Meeting
Tetra Tech will review the Source Water Assessment and will meet with the City of Muskegon to refine
the scope for this project.

1.2: Update the 2017 Muskegon Source Water Intake Protection Plan
The current assumption is that little has changed regarding the identified land use threats in the 2017 plan
based on the the 2003 Susceptibility Determination. Essentially, the first four elements of an approvable
SWIPP are covered by the assessment, so it will need to be updated. Tetra Tech will update the assessment
information as agreed upon during the implementation of Task 1.1. Based on our preliminary review of
the existing assessment, it is anticipated that the following plan updates will be necessary:
        Contact List for SWIPP
         The City of Muskegon will provide contact names for the SWPP team and Tetra Tech will update
         the plan (from the assessment information) to reflect current team members.

        The Assessment Inventory
         Tetra Tech will search the government environmental databases and update the assessment
         information for other land uses to be considered for inclusion in the SWIPP. It is anticipated that
         the following databases will be reviewed:
         o EGLE leaking underground storage tank (LUST) sites;
         o EGLE registered underground storage tank (UST) sites;
         o EGLE Environmental Cleanup Site Information System (ECSI) sites;
         o EGLE Source Information System (for water discharge permit sites including National
             Pollutant Discharge Elimination System (NPDES) permits, Water Pollution Control
             Facility (WPCF) permits, storm water discharge permits, and on-site sewage (septic) system
             permits);
         o EGLE Underground Injection Control (UIC) database;
         o EGLE Active Solid Waste Disposal Permits list;
         o Michigan Department of Transportation (MDOT) - Hazardous Materials database;
         o State Fire Marshall registry of above-ground fuel storage tank sites;
         o State Fire Marshall Hazardous Material Handlers and Hazardous Material Incidents
             (HAZMAT) sites;
         o U.S. EPA BASINS software, version 2.1;
         o U.S. EPA Envirofacts database;

             System (IIMIRS).


In addition to the database review results, Tetra Tech will review the following:
       Aerial photographs;
       If needed, Tetra Tech will verify the database search results using windshield surveys and
        interviews with City officials. Tetra Tech will update the Potential Contaminant Source Inventory
        Map that is provided in the assessment with the current potential contaminant sources.

1.3: Recommendations/Response Plan and Timeline
Based on discussions with the City, and Tetra Tech’s expertise, a list of recommendations will be
developed and prioritized. A timeline for the implementation of the recommendations will also be
developed. Tetra Tech will review the existing emergency response and make additional recommendations
for the most likely contaminants that might occur.

1.4: Cost Estimates and Alternative Funding Sources
Cost estimates for implementing the recommendations will be developed. Where applicable, alternative
funding sources will be presented for which the City may consider applying to offset the cost of
implementing the recommendations.

1.5: Perpetuating the Plan
The EGLE has a recommendation that SWIPPs be updated every six years. Tetra Tech will recommend
steps the City can take to ensure the plan data is being continually updated, thus ensuring that if future
policy changes are required they are based on the best available information.

TASK 2.0 PUBLIC ENGAGEMENT PLAN (PEP)
In partnership with the City, Tetra Tech proposes to design a community engagement process that will
support the Surface Water Intake Protection (SWIP) planning effort. The PEP team will ensure seamless
alignment of public engagement activities and ongoing communication through participation in select
meetings with the project team (City staff, the West Michigan Shoreline Regional Development
Commission, and others).
It is anticipated that the following tasks will be part of the PEP.

Task 2.1: Public Meetings:
Host three public meetings, to be staged at logical intervals throughout the project, as follows:
    1. An initial public meeting to announce the launch of the SWIPP project, sharing a high-level
       orientation that includes project goals, timeline, and public engagement opportunities;
    2. A second public meeting to present the early findings from the project team’s benchmarking of
       peer communities; feedback will be welcomed and collected in the interest of forming the plan’s
       final content; and
    3. Finally, a third public meeting will share the SWIPP in its final form, including a description of
       the prioritization process as well as the context of how the SWIPP reflects feedback gathered
       through the public engagement process and the work of the SWIPP Team, with anticipated next
       steps and implications.




Tetra Tech                                                                                 Page 3 of 5
One consultant will be present at each of the public meetings. Each meeting is anticipated to require 90
minutes.



Task 2.3: Progress Meetings
Lead by Tetra Tech, the PEP team will participate in progress meetings with the City of Muskegon and
project team. Project progress meetings are in the Project Management Task outlined below. It is not
anticipated that all personnel will be physically present and that some people may phone or video cast into
the meetings.
Task 2.4: Meeting Minutes and Content
The PEP Team will review all existing documentation from previous public engagement efforts as well as
prepare, refine, and finalize supporting documentation (e.g., meeting agendas/summaries; presentation
materials) and other content (e.g., to be used for the project website, press releases, social media, mailings)
as needed to advance the work.
Additionally, this proposal reflects a modest accommodation for the necessary project-related email and
phone communication to occur throughout the course of the project.

TASK 3.0 PROJECT MANAGEMENT AND DELIVERABLES
Project management will consist of weekly internal monitoring of the project status and budget. Progress
with the City’s SWIPP steering committee are also important and we propose three meetings occurring at
the following times:
       Kickoff
       An intermediate meeting to review progress and interim deliverables.
       A meeting to review the draft report and plan for the first public presentation.
We anticipate delivering a digital copy of the draft SWIPP. Upon receiving the City’s final comments, we
will update the SWIPP and deliver a PDF copy of the final report. We anticipate the final SWIPP to be a
10- to 20-page document inclusive of figures.
We suggest that the SWIPP be structured as per the EGLE guidance with the following program headings:
       Basic Information
       Defining roles and duties of government units and water supply agencies
       Designating the source water protection area (SWP)
       Identification of potential sources of contaminants within the SWP area
       Identifying available management approaches for protection of the source water
       Contingency plans and alternative drinking water sources
       Assuring proper siting of new water sources
       Encouraging public participation

ASSUMPTIONS
The following assumptions were considered in developing a scope of work and pricing for this proposal:
       The current water production is the same as it was when the existing SWIPP was completed.
       The SWIPP will be delivered in PDF format.
       Presentations to the City Council are not included.
       Meeting room costs (if necessary) will be borne by the City of Muskegon.
       There will be no more than three progress meetings with the City team.

         No water quality monitoring or modeling will be done on this assignment.
         Implementation and development of recommendations (e.g., writing model zoning ordinances for
          upstream communities) are not included in the scope.

IMPLEMENTATION SCHEDULE
Based on the above Scope of Services, Tetra Tech anticipates the date for completion of the Source Water
Intake Protection Plan to be prior to the grant period ending August 30, 2023. The following timeline will
be used for milestones:

Commission Meeting Date: October 25th, 2022                             Title: Splashpad RFQ

Submitted By: Leo Evans                                                 Department of Public Works

Brief Summary:
Staff requests authorization to issue a request for qualifications to replace the downtown splash pad.

Detailed Summary & Background:
During the summer of 2022 the downtown splash pad was subject to frequent breakdowns and
disruptions in service. An extensive amount of resources were put towards the project on numerous
occasions to provide what little operational use the site was able to provide in 2022. Late in 2022 the
system failed again and it was determined in the best interest to close it for the remainder of the year
rather than continue to try and limp the system along. Repair options for the existing system are still
being evaluated, however even if a repair is feasible it is unlikely to be more than a stopgap measure
and there is a high likelihood of numerous service interruptions and resource requirements during the
2023 season.

Staff is requesting approval to issue the attached request for qualifications to begin the next phase of
this project which will start to envision a long term replacement for the site. The process is planned for
a similar rollout to how the playgrounds at Reese and Beukema were completed. Proposals received
through the RFQ process will be reviewed and shortlisted by a team of stakeholders and then
presented to the Commission and Public for additional feedback. Construction of a new site for use in
2023 is a potential that we will request of those submitting a proposal for the project.

No funds are currently allocated towards this project and financial resources would need to be
identified to support the completion of this project. To that end staff is preparing an application to the
Michigan Spark Grant program, which aims to distribute 65 million dollars from Michigan’s federal
Investment in Infrastructure and Jobs Act (IIJA) disbursement into the state’s parks systems. The
application period closes December 19th, with awards to follow in three tranches in the winter, spring
and summer of 2023.

                           SPECIFIC PROJECT INFORMATION


INTRODUCTION TO PROJECT

The City of Muskegon is seeking proposals from qualified companies to design and construct a
new splash pad to replace the existing splash pad located in the 200 Block of West Western
Avenue adjacent to the City Farmers Market, the Post Office and Alcoa Square.

Approximate Location - https://goo.gl/maps/SDBbbc9SyiQWZjy59

The existing splash pad is currently non-functional and the City is requesting that companies
provide the following documents as a part of this RFP related to the replacement of the existing
facility:

   •   Site specific conceptual design including renderings and site amenities as necessary to
       properly convey the proposed design for the site.

   •   Full turnkey cost estimate for the demolition of the existing site and construction of the
       new facility. Inclusive of any administration, permitting, and other soft costs.

   •   A conceptual project schedule based on receiving a notice to proceed in January 2023.

Plans for the existing splash pad and site are included as an attachment to this document for
reference along with an aerial view of the site showing the approximate existing public utility
features of the site. Pictures can be provided upon request for interested firms that are unable to
visit the site in person.

Site Design Considerations

   •   Proposed site design cannot permanently impact the surrounding amenities including seat
       walls, art work, landscaping, trees, etc…

   •   Design should be at least as large as the existing splash pad which is approximately a 40
       FT diameter circle (1,250 SFT). Designs can be larger to utilize more of the surrounding
       space provided there are no impacts to the adjacent features.

   •   Design should have primary features be above ground installations.

   •   Design should be geared towards all ages of youth use.

   •   The design must be universally accessible.

   •   The design should be based on a non-recirculating system. The existing system was
       designed for recirculation and later converted to non-recirculating. The design should
       include an estimated annual water usage for purposes of estimating the operating costs.


                                                 6
   •   City is requesting turnkey cost proposals for this project in the range of $400,000.

   •   The proposal should include a conceptual schedule for the project based on a notice to
       proceed in January 2023 and identifying a target date that the site could be operational.

Questions on the above phasing can be submitted to Leo Evans via email
(Leo.Evans@shorelinecity.com). Questions received prior to Monday, November 14th, 2022 will
receive a response prior to the acceptance of the RFP. Requests received after that date will
receive a response pending staff availability.

                         CONTENTS OF PROPOSAL SUBMITTAL


At a minimum, each proposal shall include the following items:

CONCEPTUAL DESIGN RENDERINGS
Presentation quality, site specific design renderings showing the general layout of the site from
various views. Renderings should be set to convey a clear and concise conceptual layout;
highlight the overall size of the splash pad; how the proposed design fits into the existing site;
specific noteworthy features/amenities of the site; and options for color schemes. The site
should highlight Muskegon and in particular the downtown city core.


TURNKEY COST ESTIMATE
Provide a cost estimate for the full scope of the project inclusive of all features needed from start
to finish on the project. City has identified a target cost of $400,000 for the project and will
provide additional scoring points to projects that can deliver a successful project below that
threshold.


PROJECT SCHEDULE
Provide a conceptual schedule for the project based on a January 2023 notice to proceed for
consideration by the staff/commission/stakeholders.


                                         EVALUATION

Staff and Stakeholders will review the submitted proposals and make a recommendation to the
City Commission based on a qualifications based selection.

                        Muskegon City Commission
Commission Meeting Date: October 25, 2022            Title: Stormwater Management Ordinance

Submitted By: Dan VanderHeide                        Department: Public Works

Brief Summary: A new stormwater ordinance for adoption that puts the City in responsible charge
for stormwater management reviews for new developments and other similar situations.

Detailed Summary & Background: The City has used the Muskegon County Drain Commissioner’s
Office for storm water management reviews of new development since about October of 2016. In
2021 the City began the process of taking back management of our own storm water reviews to
increase quality and control over the process and to speed review times. Staff has been working with
ENG. Inc. to prepare a new storm water ordinance that will allow the City to formally take back control
of storm water management with an ordinance and other documents in compliance with our state
permitting requirements and EGLE procedures. The City attorney has reviewed the ordinance.
Developers will see little change to the process, as the new ordinance and rules are designed very
similar to the County standards we now use, and reviews will continue to be performed by ENG. Inc.,
the same consultant that performs reviews for the County. What changes do occur are anticipated to
be positive to both the City and developers, with the goal of increasing service and practicality of
application.
The ordinance and associated procedures manual were presented for review at the October 10 Work
Session meeting. Both documents will require review by the state, however in a quirk of procedure
the state will not approve the documents until adopted. Given the similarity of these documents and
rules to those of other Muskegon County governments and similar governments throughout the state,
staff and the consultant anticipate minimal comments from the state, if any.

Focus Area Addressed: Sustainability in financial practices and infrastructure.

Sec. 26-501 Statutory authority and title.

     This Article (Article V of Chapter 26 of the City Code of Ordinances) is adopted
     in accordance with the Home Rule City Act, as amended, Public Act 279 of 1909
     (MCL 117.1 et seq.); the Michigan Drain Code of 1956, Public Act 40 of 1956
     (MCL 280.1 et seq.); the Land Division Act, Public Act 288 of 1967 (MCL

     Control Act (also known as the Clean Water Act), as amended (33 U.S.C. §
     1342(p) and 40 CFR 9, 122, 123 and 124); and other applicable state and
     federal laws.

This Article shall be known and may be cited as the City of Muskegon Stormwater
Management Ordinance.

Sec. 26-502 Findings.

The City finds that:

1. Water bodies, roadways, structures, and other property within, and downstream of
   the City are at times subjected to flooding;
2. Flooding is a danger to the lives and property of the public and is also a danger to
   the natural resources of the City and the region;
3. Land development alters the hydrologic response of watersheds, which may result
   in increased stormwater runoff rates and volumes, increased flooding, increased
   stream channel erosion, and increased sediment transport and deposition;
4. Stormwater runoff produced by land development may contribute to increased
   quantities of waterborne pollutants; Increases of stormwater runoff, soil erosion,
   and nonpoint source pollution may have occurred as a result of land
   development, and may cause deterioration of the water resources of the City
   and downstream municipalities;
5. Stormwater runoff, soil erosion, and nonpoint source pollution, may have
   resulted in a deterioration of the water resources of the City and downstream
   municipalities;
6. Increased stormwater runoff rates and volumes, and the sediments and
   pollutants associated with stormwater runoff, absent reasonable regulation and
   control, can adversely affect the City's water bodies and water resources, and
   those of downstream municipalities;
7. Stormwater runoff, soil erosion, and nonpoint-source pollution can be controlled
   and minimized by the regulation of stormwater runoff from development;


F:\EDSI\FILES\00100\1693.02\ORDIN\14Y6777.DOCX
8. Post-Construction Storm Water Runoff Program requirements for new and
   redevelopments within the City are set forth in the State of Michigan National
   Pollutant Discharge Elimination System Permit Application for Discharge of
   Storm Water to Surface Waters of the State from a Municipal Separate Storm
   Sewer System (DEQ, 2013 Rev. 10/2014);
9. Adopting the standards, criteria and procedures contained in this Article and
   implementing the same can address many of the deleterious effects of
   stormwater runoff;
10. Adopting these standards is necessary for the preservation of the public health,
    safety and welfare;
11. Adopting these standards is necessary to comply with the NPDES MS4 Permit.
12. Illicit discharges may contain pollutants that can significantly degrade the City's
    water bodies and water resources;
13. Illicit discharges enter the MS4 through either direct connections (e.g.,
    wastewater piping either mistakenly or deliberately connected to the storm
    drains) or indirect connections (e.g., infiltration into the stormwater drainage
    system or spills connected by drain inlets);
14. Establishing the measures for controlling illicit discharges and connections
    contained in this Article and implementing the same will address many of the
    deleterious effects of illicit discharges.

Sec. 26-503 Purpose.

It is the purpose of this Article to establish minimum stormwater management
requirements and controls to accomplish, among others, the following objectives:
  1. To reduce artificially induced flood damage;
 2. To minimize increased stormwater runoff rates and volumes from identified new
    land development;
 3. To minimize the deterioration of existing watercourses, culverts and bridges, and
    other structures;
 4. To encourage water recharge into the ground where geologically favorable
    conditions exist;
 5. To prevent an increase in nonpoint source pollution;
 6. To maintain the integrity of stream channels for their biological functions, as well
    as for drainage and other purposes;
 7. To minimize the impact of development upon stream bank and streambed
    stability;
 8. To reduce erosion from development or construction projects;


F:\EDSI\FILES\00100\1693.02\ORDIN\14Y6777.DOCX
 9. To preserve and protect water supply facilities and water resources by means of
    controlling increased flood discharges, stream erosion, and runoff pollution;

 10. To reduce stormwater runoff rates and volumes, soil erosion, and nonpoint
     source pollution, wherever practicable, from lands that were developed without
     stormwater management controls meeting the purposes and standards of this
     Article;
 11. To reduce the adverse impact of changing the land use along water bodies
     and, to that end, this Article establishes minimum standards to protect water
     bodies from degradation resulting from changing land use where there are
     insufficient stormwater management controls;
 12. To regulate the contribution of pollutants to the MS4 by stormwater discharges by
     any user;
 13. To prohibit illicit discharges and connection to the MS4;
 14. To establish legal authority to carry out all inspection, surveillance, monitoring
     and enforcement procedures necessary to ensure compliance with this Article.

   a fine of not more than $500 or imprisonment in the county jail for not more than
   93 days, or both such fine and imprisonment, and such person shall also pay
   such costs as may be imposed in the discretion of the court.

5. Any person who aids or abets a person in a violation of this Article shall be subject
   to the sanctions provided in this section.

Sec. 26-557 Stop work order.

Where there is work in progress that causes or constitutes in whole or in part, a
violation of any provision of this Article, the City is authorized to issue a stop work
order so as to prevent further or continuing violations or adverse effects. All persons
to whom the stop work order is directed, or who are involved in any way with the
work or matter described in the stop work order, shall fully and promptly comply
therewith. The City may also undertake, or cause to be undertaken, any necessary
or advisable protective measures so as to prevent violations of this Article or to
avoid or reduce the effects of noncompliance herewith. The cost of any such
protective measures shall be the responsibility of the owner of the property upon
which the work was performed.

Sec. 26-558 Failure to comply.

In addition to any other remedies, should any owner fail to comply with the
provisions of this Article, the City may, after the giving of reasonable notice and
opportunity for compliance, have the necessary work done, and the owner shall be
obligated to promptly reimburse the City for all costs of such work.

Sec. 26-559 Emergency measures.

When emergency measures are necessary to moderate a nuisance, to protect
public safety, health and welfare, and/or to prevent loss of life, injury or damage to

measures. Property owners shall be responsible for the cost of such measures made
necessary as a result of a violation of this Article and shall promptly reimburse the
City for all of such costs.

Sec. 26-560 Cost recovery for damage to stormwater drainage system.

A discharger shall be liable for all costs incurred by the City as the result of causing
a discharge that produces a deposit or obstruction, or causes damage to, or impairs
a storm drain, or violates any of the provisions of this Article. Costs include, but are
not limited to, those penalties levied by the EPA or EGLE for violation of an NPDES
permit, attorney fees, and other costs and expenses.

Sec. 26-561 Collection of costs; lien.

Costs incurred by the City pursuant to Sections 26-531, 26-536 and 26-538 shall be
a lien on the premises which shall be enforceable in accordance with the Revenue
Bond Act, Public Act 94 of 1933 (MCL 141.101 et seq.). Any such charges which
are delinquent for six (6) months or more may be certified annually to the City
Treasurer, who shall enter the lien on the next tax roll against the premises and the
costs shall be collected and the lien shall be enforced in the same manner as
provided for in the collection of taxes assessed upon the roll and the enforcement of
a lien for taxes. In addition to any other lawful enforcement methods, the City shall
have all remedies authorized by such Act.

 Sec. 26-562 Appeals.

 1. Any person to whom any provision of this Article has been applied may appeal
    in writing, not later than thirty (30) days after the action or decision being
    appealed from, to the City commission the action or decision whereby any such
    provision was so applied. Such appeal shall identify the matter being appealed,
    and the basis for the appeal. The City commission shall consider the appeal
    and make a decision whereby it affirms, rejects or modifies the action being
    appealed. In considering any such appeal, the City commission may consider
    the recommendations of the City Engineer and the comments of other persons
    having knowledge of the matter. In considering any such appeal, the City
    commission may grant a variance from the terms of this Article so as to provide
    relief, in whole or in part, from the action being appealed, but only upon finding
    that the following requirements are satisfied:

         a. The application of the Article provisions being appealed will present or
            cause practical difficulties for a development or development site;
            provided, however, that practical difficulties shall not include the need for
            the developer to incur additional reasonable expenses in order to comply
            with the Article; and

         b. The granting of the relief requested will not substantially prevent the goals
            and purposes sought to be accomplished by this Article, nor result in less
            effective management of stormwater runoff.

 Sec. 26-563 Suspension of MS4 access.

 1. Suspension due to illicit discharges in emergency situations. The City may,
    without prior notice, suspend MS4 discharge access to a person when such
    suspension is necessary to stop an actual or threatened discharge, which
    presents or may present imminent and substantial danger to the environment,
    or to the health or welfare of persons, or to the MS4. If the violator fails to
    comply with a suspension order issued in an emergency, the City may take such
    steps as deemed necessary to prevent or minimize damage to the MS4 or the
    environment, or to minimize danger to the health or welfare of persons.
 2. Suspension due to the detection of illicit discharge. Any person discharging to the
    MS4 in violation of this Article may have the person's MS4 access terminated if
    such termination would abate or reduce an illicit discharge. The City will notify a
    violator of the proposed termination of the violator's MS4 access. A person
    commits an offense if the person reinstates MS4 access to premises terminated
    pursuant to this section, without the prior approval of the City.

 Sec. 26-564 Tracking enforcement.

The City shall implement a method for tracking instances of non-compliance. The
tracking procedure shall ensure that detailed information about non-compliance and
follow up enforcement action is adequately documented, including at a minimum:

  1. Name of the person responsible for violating the ordinance;
  2. Date and location of violation;
  3. Description of the violation, including how the violation was identified;
  4. Description of the enforcement response;
  5. Schedule for returning to compliance
  6. Date the violation was resolved.

                                  DIVISION 7
                Stormwater Easements and Maintenance Agreements

Sec. 26-571 Applicability of requirements.

The requirements of this division concerning stormwater easements and
maintenance agreements shall apply to all persons required to submit a drainage
plan to the City for review and approval.




F:\EDSI\FILES\00100\1693.02\ORDIN\14Y6777.DOCX
Sec. 26-572 Stormwater easements.

The developer shall provide all stormwater easements necessary to implement the
approved drainage plan and to otherwise comply with this Article in form and
substance required by the City, and shall record such easements as directed by the
City. The easements shall ensure access for proper inspection and maintenance of
stormwater management facilities and shall provide adequate
emergency overland flow-ways. Easements for private stormwater management
systems shall be conveyed by each landowner to the entity responsible for
operation and maintenance of the stormwater management system. The City will
not accept easements over private stormwater management systems.

Sec. 26-573 Maintenance agreements.

1. A maintenance agreement is required for all developments requiring stormwater
   review. The developer shall provide all stormwater maintenance agreements
   necessary to implement the approved drainage plan and to otherwise comply
   with this Article in form and substance as required by the City. The maintenance
   agreement shall be signed and submitted to the City for review and approval at
   the time application for a stormwater permit is made. After construction of the
   stormwater management system has been verified and approved or accepted by
   the City, the Developer shall execute a final maintenance agreement with the
   City, record such agreements with the County Register of Deeds, and provide a
   copy of the recorded document to the City. The City reserves the right to require
   the maintenance agreement be recorded prior to issuance of a stormwater permit.

2. Maintenance agreement provisions. The maintenance agreement shall, among
   other matters, ensure access for proper inspection by the City or their designee,
   allow for maintenance or corrective actions of stormwater BMPs, and include
   provisions for the tracking of maintenance activities, and transfer of operation
   and maintenance responsibility to ensure the performance standards are met in
   perpetuity.

        a. Maintenance Plan. The maintenance agreement shall include a
           maintenance plan and schedule for routine, emergency and long-term
           maintenance of all structural and vegetative stormwater BMPs installed
           and implemented to meet the performance standards, with a detailed
           annual estimated budget for the initial three (3) years, and a clear
           statement that only future maintenance activities in accordance with the
           maintenance plan shall be permitted without the necessity of securing
           new permits.

        b. Maintenance Documentation. Written notice and submittal of maintenance
           documentation shall be provided to the City by the property owner at the
           interval set forth in the maintenance agreement and subject to the


F:\EDSI\FILES\00100\1693.02\ORDIN\14Y6777.DOCX
            provisions of Sections 26-546 through 26-562.

        c. Failure to Perform Maintenance. If it has been found by the City, following
           notice and an opportunity to be heard by the property owner, that there
           has been a material failure or refusal to undertake maintenance as
           required under this Article and/or as required in the approved
           maintenance agreement as required hereunder, the City shall then be
                 i. authorized, but not required, to hire an entity with qualifications and
                    experience in the subject matter to undertake the monitoring and
                    maintenance as so required, in which event the property owner
                    shall be obligated to advance or reimburse payment for all costs
                    and expenses associated with such monitoring and maintenance,
                    together with a reasonable administrative fee. The maintenance
                    agreement required under this Article shall contain a provision
                    spelling out the requirements; and if the applicant objects in any
                    respect to such provision or the underlying rights and obligations,
                    such objection shall be resolved prior to the commencement of
                    construction of the proposed development on the property. If the
                    property owner fails to pay the costs incurred by the City under this
                    Section, the costs shall be a lien on the property and enforced as
                    provided in Division 6 of Section 26.

3. Tracking Operation and Maintenance. The City shall implement a tracking
   system to include procedures for filing and retrieval of all recorded maintenance
   agreements, maintenance plans, and stormwater management system maps to
   document location and ages of stormwater BMPs. The City shall also track
   annual inspection reports required to be submitted from the developer, and any
   inspection conducted by the City to document condition of stormwater BMPs and
   maintenance performed.

Sec. 26-574 Prohibition of orphan drains.

Prior to issuance of a stormwater permit, all stormwater management systems must
have a single entity responsible for long-term operation and maintenance. The City
will not approve an “orphan” drainage system serving multiple landowners without
recorded stormwater easements and maintenance agreements.

Sec. 26-575 through Sec. 26-580. (Reserved)

                                         DIVISION 8
                              Performance and Design Standards

Sec. 26-581 Resolution to implement performance and design standards.

The City Commission may adopt a resolution establishing detailed design and


F:\EDSI\FILES\00100\1693.02\ORDIN\14Y6777.DOCX
performance standards for stormwater management facilities, consistent with the
terms of this Article, and in order to further implement the goals and purposes set
forth in this Article. Amendments to the design and performance standards must be
approved by the City Commission.

Sec. 26-582 Performance standards.

In order to achieve the goals and purposes of this Article, sites shall meet the
stormwater management performance standards for water quality treatment, channel
protection, flood control, and other site-specific standards as published in the City’s
Stormwater Management Standards.

Sec. 26-583 Alternatives for meeting performance standards.

1. The City may establish programs and procedures for alternative means to meet the
   channel protection performance standard if onsite retention is determined to be
   not feasible.

2. Requirements for programs and procedures (if any) adopted by the City are given
   in the City’s Stormwater Management Standards.

Sec. 26-584 Design standards.

Stormwater BMPs shall be designed to meet the performance standards as
described in Section 26-582. Stormwater management system design shall be in
accordance with the City’s Stormwater ManagementStandards.

Sec. 26-585 Responsibility to implement best management practices (BMPs).

The owner or operator of a commercial or industrial establishment shall provide, at
the owner’s or operator’s own expense, reasonable protection from accidental
discharge of prohibited materials or other wastes into the City’s stormwater
drainage system or waterbodies through the use of these structural and non-
structural BMPs. Further, any person responsible for a property or premises, which
is or may be the source of an illicit discharge, may be required to implement, at said
person’s expense, additional structural and non-structural BMPs to prevent the
further discharge of pollutants to the MS4. Compliance with all terms and conditions of a
valid NPDES permit authorizing the discharge of stormwater associated with industrial
activity, to the extent practicable, shall be deemed compliance with the provisions of
this section. These BMPs shall be part of a stormwater pollution prevention plan
(SWPPP) as necessary for compliance with requirements of the NPDES permit.

                                                           PART 1 – GENERAL PROVISIONS

I. PURPOSE
This manual was produced to update and unify site plan review procedures within City of Muskegon. It is the
purpose of these site development rules to establish a uniform set of minimum standards for the management of
stormwater to be applied city-wide and meet the following objectives:
   1. Ensure stormwater drainage systems are adequate to address stormwater management needs within a
      proposed development, and protect the drainage, property, and water rights of landowners outside of
      the proposed development.
   2. Reduce flood damage due to development.
   3. Minimize the degradation of existing watercourses.
   4. Prevent an increase in nonpoint source pollution.
   5. Maintain site hydrology to avoid detrimental changes in the balance between stormwater runoff,
      groundwater recharge, and evapotranspiration.

The City has applied the Muskegon County Water Resources Commissioner Site Development Rules with
Procedures and Design Standards for Stormwater Management Systems, since adoption by City Commission on
October 25, 2016. This manual was developed to update and unify site plan review procedures pertaining to
stormwater within the City and supplement the City’s newly adopted Stormwater Ordinance. This manual was
developed to comply with state and federal stormwater guidelines.

A. Compliance with State and Federal Stormwater Mandates
Drains located within an urbanized area defined by the United States Environmental Protection Agency (EPA)
are considered MS4s. The City is required to obtain an individual NPDES MS4 permit under Section 402 of the
Federal Clean Water Act, as amended, and under Water Resources Protection (Part 31, Act 451, PA 1994) of
the Michigan Natural Resource and Environmental Protection Act, as amended. An application for an MS4
permit was submitted to EGLE on April 1, 2016.
The MS4 permit requires the City to adopt an ordinance or other regulatory mechanism to address post-
construction stormwater runoff from new development and redevelopment projects, including preventing or
minimizing water quality impacts. The Post-Construction Stormwater Runoff Program of the MS4 permit
requires among other things:
   1. A water quality performance standard to ensure specified reductions in total suspended solids.
   2. A channel protection performance standard to address resource impairments resulting from increases in
      bankfull flow rates and volumes.
   3. A review procedure for the evaluation of infiltration best management practices (BMPs) to meet water
      quality and channel protection standards in areas of soil or groundwater contamination.
   4. Measures to address associated pollutants in identified "hot spots," which include land uses with the
      potential for significant pollutant loading that could result in the contamination of surface water or
      groundwater, including public water supplies.
   5. A long-term operation and maintenance plan and agreement allowing for inspection, including a
      mechanism for tracking the transfer of operation and maintenance responsibility and compliance.
The minimum standards in this manual meet the Post-Construction Storm Water Runoff Program requirements
for new and redevelopments set forth in the State of Michigan National Pollutant Discharge Elimination System
Permit Application for Discharge of Storm Water to Surface Waters of the State from a Municipal Separate Storm
Sewer System (DEQ, 2013, Rev 10/2014).

TMDLs
The MS4 permit also requires identification and prioritization of actions to reduce pollutants in stormwater
discharges to make progress in meeting Total Maximum Daily Load (TMDL) Water Quality Standards. TMDL water
bodies in City of Muskegon are summarized below:


 TDML Waterbody                     Pollutant                         Pollutants(s) of Concern
 Little Black Creek                 Biota                             Sedimentation and Siltation
 Black Creek                        Biota                             Sedimentation and Siltation
 Ruddiman Creek                     E. Coli                           Human and wildlife, pathogens, refuse, illicit
                                                                      discharges


 B. Preferred Stormwater Management Strategies
 Regional Stormwater Management
 The management of stormwater on a regional basis is encouraged where practical, particularly where site
 constraints may preclude effective onsite treatment of stormwater. A regional stormwater management
 approach allows for the use of superior performing BMPs that require more space and provides more flexibility
 for BMPs to be sited strategically to address a known water quality issue.

 Developers are encouraged to pursue a regional approach for private facilities where practical. Specific
 requirements are provided in Part 2 section “Regional Stormwater Management Facility.”

 Flood Control
 The prevention and mitigation of property damage caused by flooding is priority for the City. The standards for
 flood control require among other things:
     1. A minimum flood control volume to be retained or detained onsite with provisions for emergency
         overflow.
     2. Confirmation of an adequate outlet for the discharge of stormwater offsite.

 Alternatives for Channel Protection
 An alternative approach using extended detention is allowed by EGLE for the urbanized area within the City of
 Muskegon when the full channel protection volume cannot be retained onsite, and offsite options are not
 available. These standards define the conditions under which the alternative approach will be approved for use. A
 flow chart outlining this process is shown on the following page. Specific requirements are provided in Part
 3 section “Channel Protection.”

 Off-site mitigation for channel protection is allowed where physical constraints of individual sites may preclude
 effective onsite treatment. Specific requirements are provided in Part 2 section “Off-site Mitigation.”

 Payment-in-lieu for channel protection will only be allowed if a program is available from the City or as set forth
 in a Watershed Policy Statement. Specific requirements are provided in Part 2 section “Payment-in-lieu.”

 Limiting site conditions can be addressed using off-site mitigation or payment-in-lieu (offsite options), the
 alternative approach (onsite option), or a combination of these options as the City sees fit, only if the use of all
 other onsite BMPs has been maximized.

Low Impact Development
Where regional stormwater management is not available to developers, onsite Low Impact Development (LID) is
the preferred stormwater management strategy to meet the multiple objectives identified previously. LID uses
the basic principle modeled after nature to manage rainfall where it lands. The outcome of LID is mimicking
existing site hydrology by using design techniques to infiltrate, filter, store, evaporate and detain runoff close to
its source. Many of these techniques incorporate the use of vegetation and are collectively referred to as Green
Infrastructure. A LID approach offers additional benefits in terms of increased property value and potential cost
savings.2 The size of stormwater storage facilities and infrastructure can often be reduced by incorporating LID
principles into a site design up front.

The Low Impact Development Manual for Michigan (SEMCOG, 2008) was used to develop this manual. The
standards in this manual incorporate LID principles into the design process and include design criteria for LID and
small site BMPs.

Chapter 26 Environment, Article V (Stormwater Management), provides for the regulation and control of
stormwater runoff and establishes procedures for obtaining a stormwater permit as part of the site plan approval
process. These published Stormwater Standards are established pursuant to and incorporated by reference into the
Stormwater Ordinance.

B. Provisions for Requirements in Addition to Minimum Standards
This manual provides minimum standards to be complied with by Developers and in no way limit the authority of
the City to adopt or publish and enforce higher standards as a condition of approval of the final plat or site plan.
The City reserves the right to determine site-specific requirements other than those herein, based upon review of
the plans. Any deviations from these standards shall be subject to approval by the City.

III. APPLICABILITY
A. Review Required
These standards apply to private and public development and redevelopment projects in City of Muskegon. These
standards also apply to City owned facilities and City Public Works projects, including road projects.

Developments subject to review under these Standards, limited to City review, and exemptions are identified in
Section 26-304 of the Stormwater Ordinance.

IV. SEVERABILITY CLAUSE
If any part of these rules is found to be invalid, such invalidity shall not affect the remaining portions of the rules
which can be given effect without the invalid portion, and to this end the rules are declared to be severable.

V.      ADOPTION AND REVISION
The City council has adopted these Stormwater Standards by approval of the Stormwater Ordinance at the October
25, 2022 City Commission meeting. The effective date of these standards is November 1, 2022. Revisions to the
standards or fees will be subject to review and approval by City Council.

Revisions to the standards affecting MS4 permit requirements must be reviewed and approved by EGLE, if required
by law.

VI. FEES

          PART 2 - PROCEDURES FOR PLAN SUBMISSION AND APPROVAL
I.    SUBMISSION AND APPROVAL
These procedures have been developed in the context of the plat requirements specified in the Land Division Act,
which lays out a two-step submittal and approval process. A preliminary plat and final plat are required by statute.
For other types of developments, submittal of a condominium subdivision plan, preliminary plan, or site plan is
required, which will typically culminate in a final set of construction drawings.

A. Concept Review Meeting
A concept review meeting is strongly encouraged prior to submittal of a site plan. The purpose of the concept
review meeting is to initiate communication and provide uniform direction to the Developer to maximize
efficiency in design and reduce costs.
The Proprietor is responsible for contacting the City’s office to request the meeting, submit the concept plan,
and coordinate the location, date, and time for the meeting with all parties involved. Information provided by
the Proprietor in the concept plan shall include at a minimum the items on the Stormwater Review Checklist.
If the conceptual layout of the drainage plan is approved, the Developer may begin completing design plans and
calculations for application submittal under these Standards.

B. Submission
The following submittals are required for City review and approval prior to the start of any work on the proposed
development requiring review under these rules. Soil borings and test pits, soil testing, vegetative cutting solely for
land surveys, and normal maintenance shall not be considered a start of work under these rules. An application
packet is available from the City.
Site Plan Review
     1. Site Plan Review Application.
     2. Stormwater Worksheet and calculations prepared by a professional engineer licensed in the State of
        Michigan.
     3. Drawings. Initial submission requires one (1) print and one (1) electronic PDF file containing the
        information on the Stormwater Review Checklist prepared by a professional engineer or surveyor
        licensed in the State of Michigan. Resubmittals require only one (1) electronic PDF file.
     4. Applicable fee (refer to Part 1 section "Fees").

Staged Development
Should the Developer plan to develop a given area but wish to begin with only a portion of the total area, the
original preliminary plat or site plan shall include the proposed general layout for the entire area. The first phase
of the development shall be clearly superimposed upon the overall plat or site plan in order to clearly illustrate
the method of development that the Developer intends to follow. Each subsequent plat or site plan shall follow
the same procedure until the entire area controlled by the Developer is developed.
Final acceptance by the City of only one portion or phase of a development does not ensure final acceptance of
any subsequent phases or the overall general plat or site plan for the entire area; nor does it mandate that
the overall general plat or site plan be followed as originally proposed, if deviations or modifications acceptable to
the City are proposed.

C. Changes and Resubmission
Changes made without resubmission and approval may result in revocation of approval.

If the Developer finds it advantageous or necessary to make design changes, or if the information given to the

                                                          7
          PART 2 - PROCEDURES FOR PLAN SUBMISSION AND APPROVAL
City does not represent the conditions as they exist on the ground, and revisions are required as a result, such
revisions shall be made by the Developer and the drawings resubmitted to the City for approval.

D. Approval
Payment of all fees is prerequisite to approval (refer to Section 26-314 of the Stormwater Management Ordinance.

E. Expiration of Approval
Approval of construction drawings by the City's office is valid for two (2) calendar years. If an extension
beyond this period is needed, the Proprietor shall submit a written request to the City for an extension. The City
may grant one-year extensions of the approval and may require updated or additional information, if needed.
Should modifications be made to the drawings, a new review may be required subject to the appropriate fees.

F. Revocation of Approval
Any approval issued by the City under these rules may be revoked or suspended for a violation of the conditions of
approval, or a misrepresentation or failure to disclose relevant facts in the application submittal. The City will
provide the Proprietor written notice of any revocation of approval.

G. Submission of Construction Record Drawings
Construction record drawings (“as-builts”) shall be submitted to the City for developments reviewed under
these rules. A letter of certification by a professional engineer shall accompany the construction record drawings
or may be accepted in lieu of record drawings for some projects at the City’s discretion. An Engineer’s
Certification of Construction is available from the City.
One (1) print, one (1) electronic PDF file, and one (1) electronic file meeting G I S digital submission
requirements shall be submitted, and contain the information listed on the Stormwater Review Checklist.
Construction record drawings must be submitted prior to release of any review deposit. The City will review
construction record drawings for completeness and respond with written comments or acceptance within thirty
(30) days of submittal or resubmittal.


II. STORMWATER DRAINAGE REQUIREMENTS
A.     Drainage Plan
Drainage Patterns
Proposed drainage for the development shall conform to existing watershed boundaries, natural drainage
patterns within the site, or any established county drainage districts.
Staged Development
Each phase shall be self-sufficient from the standpoint of drainage.
Location of Stormwater Management Facilities
Stormwater management facilities within a development planned to have multiple lot owners shall be located on
dedicated outlots, within road rights-of-way, or have separate easements granted to the entity responsible for
operation and maintenance of the stormwater management system.
Parking lots, roadways, walkways, and roadside ditches shall not be flooded for use as stormwater detention.
Offsite Stormwater
Surface water flows from offsite land shall be routed around the development’s onsite stormwater system
whenever possible. An onsite detention basin shall not be used to pass this flow through the site. If water from
offsite is directed through an onsite detention basin, the basin must either be designed as a regional stormwater
management facility or be sized to additionally store the existing offsite water with no change in the allowable
                                                          8
          PART 2 - PROCEDURES FOR PLAN SUBMISSION AND APPROVAL
release rate for the site.

Stormwater Discharge
The rate, volume, concentration, or constitution of stormwater discharged from a site for the specified design
storms shall not create adverse impacts to downstream properties or the public stormwater management
system. To that end, the following stormwater discharge requirements must be met for all sites:
                      i. Post-development discharge shall not exceed the capacity of the existing infrastructure
                         or the existing discharge rate from the site, whichever is lower.
                     ii. Post-development discharge shall not cause adverse impact to offsite property due to
                         concentrated runoff or ponded water of greater height, area, and duration.
                    iii. Discharge shall not cause downstream erosion or sedimentation.
                    iv. For a downstream drainage system that is inadequate to handle any increase to the existing
                         design discharge from the site development, it is the Proprietor’s responsibility to:
                             1. Stabilize or upsize the existing conveyance system.
                             2. Obtain flooding easements.
                             3. Provide additional onsite stormwater controls.
                     v. Discharge to groundwater shall not cause groundwater mounding sufficient to adversely
                         impact structures or adjacent property.
                    vi. Post-development discharge shall not cause impairments by the contribution of
                         pollutants to surface water or groundwater.
                   vii. Post-development discharge shall not cause impairments to coldwater streams due to
                         thermal properties of the discharge.
It is the Developer’s obligation to meet these requirements. Should a stormwater system, as built, fail to comply,
it is the Developer’s responsibility to have constructed at their expense, any necessary additional and/or
alternative stormwater management facilities, subject to the City’s review and approval.

B. Regional Stormwater Management Facility
Regional stormwater management facilities are designed to serve multiple developments or parcels with more
than one property owner at the time of development or redevelopment.
The City may pursue projects to serve a particular city stormwater district, or may approve facilities proposed to
be constructed by individual Developers. Private facilities must have a written agreement between responsible
parties with recorded easements to ensure operation and maintenance of the facility in perpetuity. Agreements
must specify maximum allowable runoff coefficients for each parcel contributing to the facility.
The regional facility should be constructed first, prior to any development or redevelopment. Written approval is
required from the City if construction is to be delayed. Financial surety and temporary onsite measures must
be provided until the facility is constructed.

C. Off-site Mitigation and Payment-in-lieu
Off-site Mitigation
Off-site mitigation refers to BMPs implemented at a location other than the proposed development or
redevelopment, but within the same jurisdiction and watershed/sewershed as the original project to meet
channel protection standards required by the MS4 permit. The watershed is the area represented by the DEQ, 10-
digit Hydrologic Unit Code. The sewershed is the area where storm water is conveyed by an MS4 to a common
outfall or point of discharge.
The City also requires that the off-site mitigation is protective of the same watercourse or waterbody to
which the site discharges and is located downstream of the proposed development or redevelopment if
possible.

                                                        9
           PART 2 - PROCEDURES FOR PLAN SUBMISSION AND APPROVAL
Payment-in-lieu
Payment-in-lieu refers to the Proprietor paying a fee to the City, which is then applied towards a public
stormwater management project that fulfills the channel protection and/or other stormwater requirements for
the site. The stormwater management project may be either a regional stormwater management facility, a
new BMP, or a retrofit to an existing BMP.
The City will only consider payment-in-lieu if the City has a planned or constructed improvement project
meeting the requirements for off-site mitigation as identified in a Watershed Policy Statement. The cost of
payment-in-lieu will be determined on a case-by-case basis and will represent the actual cost of implementing
public water quality enhancements.
Criteria
The determination to approve off-site mitigation or payment-in-lieu will be based on multiple criteria and not
solely on the difficulty or cost of implementing BMPs on site. Conditions under which the option to move off site
would become available may include:
       i. Limited size of the lot outside of the building footprint to create the necessary infiltration capacity even
          with amended soils.
      ii. Soil instability as documented by a thorough geotechnical analysis.
     iii. A site use that is inconsistent with capture and reuse of stormwater.
     iv. Too much shade or other physical conditions that preclude adequate use of plants.
     v. The potential water quality impact from the original project site and the benefits realized at the off-
          site location.
The City may approve off-site mitigation or payment-in-lieu if the Developer demonstrates that site constraints
preclude sufficient treatment and restoration of hydrology onsite, and the following minimum requirements
are met:
    1. Offset ratio. The offset ratio for the amount of storm water not managed onsite in relation to the amount
       of stormwater required to be mitigated at another site, or for which in-lieu payments will be made is as
       follows:
            a. First Tier: Manage a minimum of 0.4 inches of storm water runoff onsite and provide a 1 to 1.5
                offset ratio for the remaining amount of storm water managed offsite.
            b. Second Tier: If it completely infeasible to manage the minimum onsite, provide a 1 to 2 offset
                ratio for the amount of storm water managed offsite.
    2. Schedule. Off-site mitigation shall be completed within 24 months after the start of the original site
       construction.
    3. Assurances. Offset and in-lieu projects shall be preserved and maintained in perpetuity through the
       procedures and tracking system administered by the City.

D. Restrictive Covenants
For plats and site condominiums, a copy of restrictive covenants or master deed language related to drainage shall
be provided to the City along with construction drawings for approval. Covenants and deeds shall be recorded at
the Register of Deeds prior to release of posted surety.
Block Grading Plan
A block grading plan shall be incorporated in the restrictive covenants of the plat or master deed to ensure proper
drainage of individual lots. In addition, the Developer shall provide a copy of the block grading plan to the City for
their permanent files. The block grading plan shall include the Lowest Allowable Floor Elevation and Lowest
Allowable Opening Elevation for each lot and include the “basement type” for each lot (e.g., walkout, daylight,
or standard basement) as indicated by the topography of each site and according to the approved design
plans. The block grading plan shall state:


                                                         10
          PART 2 - PROCEDURES FOR PLAN SUBMISSION AND APPROVAL
        The block grading plan shows the direction of flow for the surface drainage for all lots. It is the lot
        owner’s responsibility to ensure that the final grading of the lot is in accordance with the block
        grading plan. During the final lot grading and landscaping, the owner shall take care to ensure
        that the installation of fences, planting, trees, and shrubs do not interfere with nor concentrate
        the flow of surface drainage. No changes will be made in the grading of any lot areas used for
        drainage which would later affect surface runoff drainage patterns without the prior written
        consent of the City for all portions of the drainage system. Finish grading for home construction
        shall be completed in conformance with the master drainage plan for the development and in
        such a manner so as not to create the excessive ponding of stormwater on the sites within the
        development.
Minimum Floor and Opening Elevations
Provisions for flood protection and building opening are set forth in Section 26-330 of the Stormwater
Management Ordinance. Documentation to support allowable minimum floor and opening elevations shall
be submitted with construction drawings
Criteria for determining the Lowest Allowable Floor Elevation
      i. Proximity to detention/retention facilities due to groundwater mounding (which may not be apparent
         until after construction).
     ii. Groundwater elevations from monitor wells, test pits and/or soil borings including any soil mottling noted
         in the soil profile.
    iii. Regional and cyclical groundwater levels available online.
    iv. Hydrogeologic studies and groundwater modeling.
Criteria for determining the Lowest Allowable Opening Elevation
    1. Proximity to open drain or natural watercourse, pond, or wetland and the 100-year flood elevation.
    2. Proximity to detention/retention basin and design high water level.
    3. Proximity to drainage swales and/or flood routes designed to convey the 100-year storm event runoff
         including overflows from detention/retention basins.
    4. Proximity to an enclosed storm sewer system with open ends or catch basins that could surcharge during
         the 100-year storm event.
    5. Type of building foundation (e.g., walkout, daylight, or standard basement) as dictated by the topography
         of each site.
Minimum floor and opening elevations shall be incorporated in the restrictive covenants of the plat or master
deed, including benchmark references. It is the responsibility of the Proprietor to provide a sufficient number of
benchmarks (NAVD 88 datum) to use as a reference for establishment of minimum floor and opening elevations
for all lots. Lots not impacted by high groundwater or potential flooding from a 100-year storm event as
determined by the Design Engineer shall be so noted as well. The restrictive covenant shall state:
        The lowest allowable floor elevations are set at 2-foot or more above the highest known ground
        water elevation. The lowest allowable floor and/or opening elevations are set 2-foot or more
        above the 100-year floodplain or design high water level of the stormwater system. These
        elevations are set to reduce the risk of structural damage and the flooding of building interiors. A
        waiver from the set elevations may be granted by the City following receipt of a certification
        from a professional engineer or surveyor licensed in the State of Michigan demonstrating that
        the proposed elevation does not pose a risk of flooding. Minimum building floor and opening
        elevations and benchmark locations and elevations are indicated on the Block Grading Plan.
Footing Drains and Sump Pumps
Where footing drains and sump pumps are required or utilized, a stormwater lateral shall be provided for each
parcel at the time of construction, unless a waiver is granted in writing by the City.. Provide direction in the
restrictive covenants of the plat or condominium master deed for footing drain and sump pump outlets. If
proposed to be directed to the storm sewer system, the restrictive covenant shall state:

                                                          11
          PART 2 - PROCEDURES FOR PLAN SUBMISSION AND APPROVAL
        Water from such sources as eave troughs and footing drains shall be directed to laterals provided
        for the lots. Water from footing drains shall be discharged to the lateral via a sump pump with
        check valve system. If no lateral is provided, the lot owner shall discharge said water in such a
        manner as to not impact neighboring land or public streets.
        Floor drains, laundry facilities or other similar features shall not be connected to a footing drain or
        sump pump system discharging to footing laterals and the storm sewer system. Laundry facilities
        and sewage lift pumps must discharge into the sanitary sewage disposal system.

Provisions for interference with natural of artificial drain are set forth in Section 26-338 of the Stormwater
Ordinance.
Easements for Side Yard and Surface Drainage
Private easements for enclosed yard drains and surface drainage are for the benefit of upland lots within the
development or upland sites that currently drain across the proposed plat or site. Language shall be included
within the restrictive covenants of the plat or condominium master deed that clearly notifies property owners of
the location and purpose of private easements for side yard and surface drainage, as well as restrictions on use or
modification of these areas. A separate, recordable easement form is not required. The restrictive covenant shall
state:
        Private easements for side yard and surface drainage are for the benefit of upland lots within the
        subdivision and any improper construction, development, or grading that occurs within these
        easements will interfere with the drainage rights of those upland lots. Private easements for
        surface drainage are for the continuous passage of surface water and each lot owner will be
        responsible for maintaining the surface drainage system across their property. No construction is
        permitted within a private easement for side yard and surface drainage. This includes fences,
        swimming pools, sheds, garages, patios, decks, or any other permanent structure or landscaping
        features. No dumping of grass clippings, leaves, brush, or other refuse is allowed within a drainage
        easement. These items obstruct drainage, restrict flow, and plug culverts. This can lead to higher
        maintenance costs and cause flooding situations.
Soil Erosion and Sedimentation Control Permits
It is the responsibility of the Developer to contact the Muskegon County Public Works Department (Enforcing
Agency) to determine which lots if any need a permit for Soil Erosion and Sedimentation Control (Part 91,
Act 451, PA 1994). The restrictive covenant shall state:
         Each individual lot owner will be responsible for the erosion control measures necessary on their
         lot to keep loose soil from their construction activities out of the street, catch basins, and off of
         adjacent property. If any sedimentation in the street, catch basins, or adjacent lots of results
         from construction for a particular site, it is the responsibility of that lot owner to remove the
         sediment and restore the lot to prevent further erosion. This applies to ALL lot owners.
        A Soil Erosion and Sedimentation Control Permit must be obtained from Muskegon County
        D epar tm ent of Public Works prior to excavation for lots         through           _. All conditions
        set forth by permit shall be met throughout construction activity until permit is allowed to expire.
Responsibility for Maintenance of Open Water Bodies
The restrictive covenant shall state:
        Lot owners are responsible for the management and maintenance of open water bodies for
        aesthetics, aquatic habitat, recreation, and water quality, including liability and costs. Lot owners
        are also responsible to prevent open waterbodies from becoming a nuisance due to smell or
        wildlife conditions and shall take positive action to prevent such conditions from occurring.

         PART 2 - PROCEDURES FOR PLAN SUBMISSION AND APPROVAL
E. Maintenance Plan and Agreement
Provisions for maintenance agreements are set forth below and in Section 26-373 of the Stormwater Management
Ordinance. Contact the City for necessary documents.
    A.    A maintenance agreement is required for all developments requiring stormwater review. The
          developer shall provide all stormwater maintenance agreements necessary to implement the
          approved drainage plan and to otherwise comply with this Article in form and substance as
          required by the City. The maintenance agreement shall be signed and submitted to the City for
          review and approval at the time application for a stormwater permit is made. After construction of
          the stormwater management system has been verified and approved or accepted by the City, the
          Developer shall execute a final maintenance agreement with the City, record such agreements
          with the County Register of Deeds, and provide a copy of the recorded document to the City. The
          City reserves the right to require the maintenance agreement be recorded prior to issuance of a
          stormwater permit.
    B.    Maintenance agreement provisions. The maintenance agreement shall, among other matters,
          ensure access for proper inspection by the City or their designee, allow for maintenance or
          corrective actions of stormwater BMPs, and include provisions for the tracking of maintenance
          activities, and transfer of operation and maintenance responsibility to ensure the performance
          standards are met in perpetuity.
            a.    Maintenance Plan. The maintenance agreement shall include a maintenance plan and
                  schedule for routine, emergency, and long-term maintenance of all structural and
                  vegetative stormwater BMPs installed and implemented to meet the performance
                  standards, with a detailed annual estimated budget for the initial three (3) years, and a
                  clear statement that only future maintenance activities in accordance withthe
                  maintenance plan shall be permitted without the necessity of securing new permits.

            b.    Maintenance Documentation. Written notice and submittal of maintenance
                  documentation shall be provided to the City by the property owner at the interval set forth in
                  the maintenance agreement and subject to the provisions of Sections 26-346 through 26-
                  362.

             c.   Failure to Perform Maintenance. If it has been found by the City, following notice and an
                  opportunity to be heard by the property owner, that there has been a material failure or
                  refusal to undertake maintenance as required under this Article and/or as required in the
                  approved maintenance agreement as required hereunder, the City shall then be
                     i.   authorized, but not required, to hire an entity with qualifications and experience in
                          the subject matter to undertake the monitoring and maintenance as so required, in
                          which event the property owner shall be obligated to advance or reimburse
                          payment for all costs and expenses associated with such monitoring and
                          maintenance, together with a reasonable administrative fee. The maintenance
                          agreement required under this Article shall contain a provision spelling out the
                          requirements; and if the applicant objects in any respect to such provision or the
                          underlying rights and obligations, such objection shall be resolved prior to the
                          commencement of construction of the proposed development on the property. If
                          the property owner fails to pay the costs incurred by the City under this Section,
                          the costs shall be a lien on the property and enforced as provided in Division 6 of
                          Section 26.

         PART 2 - PROCEDURES FOR PLAN SUBMISSION AND APPROVAL
    C.    Tracking Operation and Maintenance. The City shall implement a tracking system to include
          procedures for filing and retrieval of all recorded maintenance agreements, maintenance plans,
          and stormwater management system maps to document location and ages of stormwater BMPs.
          The City shall also track annual inspection reports required to be submitted from the developer,
          and any inspection conducted by the City to document condition of stormwater BMPs and
          maintenance performed.

A copy of the recorded maintenance agreement must be presented to the City prior to construction drawing
approval and release of any review deposit.

                                              PART 3 – STORMWATER REQUIREMENTS

I. SUMMARY
The following stormwater management requirements comply with the City’s Stormwater Ordinance NPDES MS4
permit and shall apply to all new developments and redevelopments in the City of Muskegon:
   1. Protection. The design process shall begin by identifying environmentally sensitive areas located on the
      site and laying out the site to maximize protection of the sensitive areas.
   2. Source Controls. Non-structural BMPs shall be used for protection of environmental sensitive areas on the
      site, and to reduce the amount of stormwater runoff.
   3. Runoff Controls. Stormwater runoff shall be managed onsite using structural BMPs to protect both water
      resources and real property. Minimum stormwater standards are summarized in Table 1. Higher
      standards may be required for sites that discharge to areas with known issues.
   4. Watershed Policy Statements. Specific stormwater management policies (if any) established for identified
      watersheds or protection areas must be met in addition to these minimum standards.
   5. Offsite Stormwater Management Options. Regional stormwater management facilities are encouraged,
      particularly where site constraints preclude effective onsite treatment of stormwater. Off-site mitigation
      and payment-in-lieu programs (if available) may be approved to meet channel protection standards.
   6. Adequate Outlet. The design maximum release rate, volume or concentration of stormwater discharged
      from a site shall not exceed the capacity of the downstream stormwater infrastructure or cause
      impairment to the offsite receiving area.
   7. BMP Design. BMPs must be designed to meet the minimum criteria provided. BMPs selected to meet the
      water quality treatment standard must also be shown to reduce TSS in stormwater runoff by at least 80%
      or to a concentration of no greater than 80 mg/L.
   8. Groundwater. The highest known groundwater elevation and extent of mounding from infiltration BMPs
      shall be determined to ensure no adverse impacts internal and external to the development.
   9. Soils. Test pits or soil borings are required for most structural BMPs to determine soil classification, depth
      to groundwater and the presence of other site constraints. Field permeability testing is not generally
      required but must be conducted to use the alternative approach for channel protection when soils are
      questionable.
   10. Restrictive Covenants. Plats and site condominium developments must incorporate specific requirements
       for lot grading, minimum floor and opening elevations, footing drains, private easements for side yard
       drainage, and individual soil erosion and sedimentation control permits.
   11. Operation and Maintenance. Stormwater BMPs must be designed to allow for operation and
       maintenance, demonstrated in the review submittals. A maintenance agreement between the Developer
       and the City is required. A maintenance plan and compliance tracking are required as part of the
       maintenance agreement.

II. STANDARDS
A. Water Quality
Where Required
Treatment of the water quality volume is required for all sites to capture and treat the “first flush” of stormwater
runoff that typically carries with it the highest concentration of pollutants.3
Standard
Capture and treatment of the runoff from the 90% annual nonexceedance storm is required for the project site.
This storm is approximately equivalent to one inch of rain (0.93 inch for Michigan Climatic Zone 5 per DEQ
memo “90 Percent Annual Nonexceedance Storms” dated March 24, 2006).
Treatment of the runoff volume from the 90% annual nonexceedance storm with properly designed BMPs to
reduce TSS loading by 80% or achieve TSS discharge concentrations not to exceed 80 mg/L, is required.
Note: TSS is a surrogate for other pollutants normally found in stormwater runoff. Control of TSS to meet this
requirement is expected to achieve control of other pollutants to an acceptable level that protects water quality.
Natural areas of the site left undisturbed and BMPs that provide water quality treatment need not be included in
the calculations. This effectively results in the directly connected impervious areas and disturbed pervious areas
of the site being used to calculate the water quality volume.
Treatment BMPs
Selected BMPs must meet the TSS target either alone or in combination. Pollutant (TSS) removal efficiencies for
BMPs are provided in Table 3. Water quality volume can be provided through one of the following methods:
    1.   Settling (Permanent Pool or Detention)
    2.   Filtration
    3.   Infiltration
    4.   Absorption
    5.   Chemical/Mechanical Treatment
Permanent Pool. The volume of a permanent pool incorporated into a stormwater BMP and sized at 2.5 times the
water quality volume.4 This is the volume below the ordinary static water level (also known as dead storage).
Detention. The storage volume provided by detention of stormwater. Extended detention is defined as holding
the stormwater runoff volume and releasing it gradually over a period of 24 hours with a drawdown time no
greater than 72 hours.
Filtration. The volume of stormwater runoff routed through a BMP that provides filtration (i.e., an underdrained
BMP). In the case of a vegetated filter strip or vegetated swale, the filtering area must meet minimum standards
for slope, length, drainage area and vegetative cover.
Infiltration. The volume of stormwater runoff infiltrated into the ground through a stormwater BMP.
Absorption and Chemical/Mechanical Treatment. The volume of stormwater runoff routed through a proprietary
water quality device, or natural or engineered system.

    B. Channel Protection
    Where Required
    Channel protection is required for surface water discharges. Channel protection is not required for direct
    discharges to Lake Michigan or Muskegon Lake, including directly connected storm sewer.
    Standard
    The post-development runoff rate and volume shall not exceed the pre-development rate and volume for all
    storms up to and including the 2-year, 24-hour storm. Retention of the volume increase is required.
    Pre-development is defined as the last land use prior to the planned new development or redevelopment.
    Retention can be provided through infiltration, or interception and evapotranspiration or reuse.
    Note: Volume control for channel protection is required to mitigate increases in runoff rates and volumes for the
    more frequent (bankfull) rainfall events that have the greatest influence on shaping stream channels. An increase
    in runoff volume can expose channels to critical erosive velocities for a longer duration, causing accelerated
    channel adjustments to occur.
    Alternative Approach
    Where site constraints limit infiltration (onsite and offsite), and field permeability testing has confirmed the limits
    of the infiltration rate, an alternative approach may be allowed after all other onsite BMPs are maximized
    consistent with the flow chart in Part 1. A certification form (Appendix 1) signed by the Design Engineer must
    be submitted for approval before the alternative approach can be used. Site constraints that limit the use of
    infiltration may include:
        1.   Poorly draining soils (<0.24 inches per hour; typically, hydrologic soil groups C and D).
        2.   Bedrock.
        3.   High groundwater, or the potential of mounded groundwater to impair other uses.
        4.   Wellhead protection areas.
        5.   Stormwater hot spots.
        6.   Part 201 and Part 213 sites, and areas of soil or groundwater contamination.
    The alternative approach shall consist of extended detention of the 2-year, 24-hour storm for a period of 24 hours
    resulting in a drawdown time no greater than 72 hours. The resulting peak discharge shall be no greater than the
    existing 1-year peak discharge.
    Note: A developed peak discharge no greater than the existing 1-year peak discharge is required by EGLE. The
    intent is to release stormwater runoff in such a gradual manner that critical erosive velocities during the bankfull
    event will seldom be exceeded in downstream channels.
    If the allowable opening area for extended detention becomes too small for practical design (less than the area of
    a ¾-inch diameter hole), a 4-inch underdrain below a biofiltration BMP (e.g., bioretention/rain garden, planter box,
    water quality swale) may be used.
    Note: Studies have shown that underdrained biofiltration BMPs provide a significant percentage of volume
    reduction (23% to 73% for 25th and 75th percentiles),5 and a large percentage of rate reduction (80% or more).6

                       PART 3 – STORMWATER MANGEMENT REQUIREMENTS
 C. Flood Control
 Where Required
 Flood control is required for all sites.
 Standard
 Detention or retention of the 25-year storm with a maximum release rate of 0.13 cfs per acre is required.
 Note: The 25-year storm is selected to balance flood risk management with economics based on federal studies
 comparing the cost of flood damage to storm return interval.7 The release rate of 0.13 cfs per acre is selected to
 be generally protective of floodplains in downstream watercourses and is based on result found in previous
 hydrologic studies on West Michigan streams.8 When volume control is not provided, an extremely low release
 rate is required to prevent an increase in peak flow rates in downstream watercourses or storm sewers. The
 increased volume and prolonged duration of runoff from multiple detention basins can have a cumulative effect
 to increase peak flow rate and duration in downstream reaches.
 An alternate maximum release rate may be allowed under certain conditions, including, but not limited to:
     1. Sites with specific discharge requirements per a Watershed Policy Statement.
     2. Redevelopment sites discharging to a municipal storm sewer where the municipality has determined the
        sewer has adequate capacity for the existing peak runoff rate from the site. Detention need only be
        provided for any increase in impervious area.
     3. Direct discharges to waterbodies or watercourses where the Developer demonstrates that the receiving
        waters possess capacity to convey the post-development discharge safely and with no negative
        downstream impacts due to increased flow rates, water levels or velocities. In addition, the peak flow of
        the receiving waters cannot be increased by the proposed development (i.e., there is a sufficient difference
        in the timing of the two hydrographs).
     4. When the site is located adjacent to or within a floodplain, excavation of new floodplain in lieu of standard
        stormwater detention may be required. The excavated volume shall be equal to the standard detention
        basin storage volume. Only the volume above the 2-year and below the 100-year floodplain elevation can
        be counted to meet the volume requirement.

 Overflow Routes for Extreme Flood
 Overflow routes and the extent of high-water levels for the 100-year flood shall be identified for the site and for
 downstream areas between the site and the nearest acceptable floodway or outlet. Provisions shall be made to
 ensure no adverse impacts offsite or internal to the site. Where acceptable overflow routes do not exist:
     1. Buildings shall be protected from flooding by two separate enclosed drainage systems, a primary and a
        redundant system, each independently protecting the building from flooding during the 100-year storm.
        Runoff shall be directed to the inlets of the primary system for up to a 10-year storm, to minimize the
        accumulation of debris over the redundant inlets; and
      2. Detention and retention basins shall be increased in size to store two (2) times the flood control volume.

                      PART 3 – STORMWATER MANGEMENT REQUIREMENTS
Note: The intent of the extreme flood criteria is to prevent flood damage from large but infrequent storm events
by identifying and/or designing overland flow paths that are clear of structures and have grades below the lowest
openings of structures. Overflow routes may include floodplains along open channels, overbank areas along
vegetated swales, curb jumps in drives and parking lots, and other flow paths flood waters will take to reach an
outlet, whether overland or underground.

D. Pretreatment
Where Required
Pretreatment is required prior to discharging stormwater runoff to the following structural BMPs to preserve the
longevity and function of the BMP:
    1.   Detention basins
    2.   Retention basins
    3.   Infiltration practices
    4.   Bioretention/rain gardens
    5.   Constructed filters
    6.   Capture reuse
Treatment BMPs
Pretreatment provides for the removal of fine sediment, trash, and debris. Methods of pretreatment include:
    1.   Forebays (including spill containment cells and level spreaders)
    2.   Vegetated filter strips (including buffers and green roofs)
    3.   Vegetated swales (including natural flow paths)
    4.   Water quality devices
Standard
Sediment Forebay
A minimum pretreatment volume equivalent to 15% of the water quality volume is required for sediment forebays
using gravity.
Note: This is a conservative approximation of results given by the Hazen Equation for sediment basin sizing using
a 50% settling efficiency for a 50-micron particle (silt) at a maximum 4-foot settling depth with a 1-year peak inflow
at a rainfall intensity of one inch per hour, consistent with recommendations in the Low Impact Development
Manual for Michigan (SEMCOG, 2008).
Vegetated Filter Strip
Provide a 10-foot minimum sheet-flow length at a maximum slope of 2% with an impervious approach length no
greater than 3.5 times the filter strip length, up to a maximum approach length of 75 feet.
Provide a 15-foot minimum sheet flow length for slopes between 2% and 6% with an impervious approach length
no greater than three times the filter strip length, up to a maximum approach length of 75 feet.
Vegetated Swale
Provide a 20-foot minimum length at a maximum slope of 4% with a 1-foot-high check dam at the downstream
end, and a maximum upstream drainage area of 0.13 acre per 2-foot of bottom width.
Note: Minimum lengths for vegetated filter strips and vegetated swales are selected to provide a workable length
for small sites and right-of-way constraints, while providing an area for sediment to drop out of suspension.
Vegetated filter strip sizing for pretreatment from Design of Stormwater Filtering Systems (Center for Watershed
Protection, 1996). Vegetated swale upstream area ratio assumes a 1-year peak inflow (rainfall intensity of
2.20 inches per hour for a time-of-concentration of 15 minutes) from an impervious area, with a settling efficiency
                                                         20
                      PART 3 – STORMWATER MANGEMENT REQUIREMENTS
of 50% for a 50-micron particle (silt).
Water Quality Device
Configured to trap floatables and sediment. Follow manufacturer’s guidelines. See notes in Table 3.

E. Hot Spots
Where Required
Sites considered to be stormwater hot spots are identified in Table 2. These include activities with a high potential
to cause contamination, and sites that have existing contamination. More specifically:
    1. Industrial and commercial land use activities involving the production, transfer, storage and/or use of
       hazardous materials in quantities that pose a high risk to surface and groundwater quality (exceeding 55
       gallons aggregate for liquids and 440 pounds aggregate for dry weights), as defined in Part 5 Rules: Spillage
       of Oil and Polluting Materials, Water Resources Protection (Part 31, Act 451, PA 1994).
    2. “Brownfield” sites with soil or groundwater contamination under Part 201 Environmental Remediation
       and Part 213 Leaking Underground Storage Tanks (Act 451, PA 1994).
Standard
Pretreatment volume with a minimum of 400 gallons required for spill containment from hot spot land use
activities.
Note: The minimum spill containment volume provides a reasonable capture size (e.g., a standard liquid propane
truck has a hauling capacity of 1,000 gallons) that can be accommodated with a 6-foot diameter water quality
device.
Pretreatment BMPs must have an impermeable barrier between the treated material and the groundwater and
have provisions for the capture of oil, grease, and sediments.
Treatment BMPs
Specific stormwater management strategies for hotspots include the following:
    1. Isolate transfer and storage areas from permeable surfaces and reduce exposure to stormwater.
    2. Identify opportunities for use of infiltration BMPs in other areas of the site.
    3. Where storage and transfer areas exposed to stormwater cannot be avoided:
       a. Infiltration of runoff from pavement surfaces is discouraged in favor of a surface water discharge.
       b. Pervious pavements that infiltrate into the groundwater are not permitted because they do not allow
           for any pretreatment or spill containment.
       c. Perforated pipes for infiltration are not permitted due to the difficulty in isolating an accidental spill.
       d. A standard catch basin and outlet pipe with a downturned end is not permitted because the area of
           the permanent pool is insufficient to prevent the captured low-density fluids from becoming
           entrained in the water when surface inflow enters the structure.
Evaluation Procedure
Brownfield sites must be evaluated before an infiltration approach can be approved so as not to exacerbate
existing conditions. The following steps must be followed for sites with known contamination:
    1. Include a qualified environmental consultant on the design team.
    2. Show areas of known contamination on the site map.
    3. Specify on the drawings how contractor is to address any contamination which may be found during
       construction.
    4. The site evaluation process must follow the document entitled Implementing Stormwater Infiltration
       Practices at Vacant Parcels and Brownfield Sites (EPA, 2013).
    5. Submit supporting documentation of the site evaluation process with the stormwater review package.

                     PART 3 – STORMWATER MANGEMENT REQUIREMENTS
     6. Contact EGLE Remediation and Redevelopment Division (RRD) staff for consultation. The final plan must
        have EGLE staff approval.

III. DESIGN PROCESS
The stormwater site design process is summarized in the steps below. This process is intended to
minimize negative impacts from development sites that could be avoided through proper planning.

A. Identify Sensitive Areas
Identify existing environmentally sensitive areas on the site plan that may require special consideration or pose
a challenge for stormwater management. For the purpose of these rules, sensitive areas include:
1.      Waterbodies (lake and ponds)                        7.    Sand dunes
2.      Rivers and streams                                  8.    Natural drainageways
3.      Floodplains (and flood prone areas)                 9.    Soils and topography (erodible, steep, karst)
4.      Riparian areas                                      10.   Susceptible groundwater supplies
5.      Wetlands                                            11.   Threatened and endangered species habitat
6.      Woodlands
Sensitive areas are determined on a site-specific basis through survey, delineation, aerial photographs, or
maps. Sensitive areas must be shown on the site map or drawings. The total acreage of protected areas must
also be indicated and demonstrate a good faith effort to maximize protection of sensitive areas.

                  PART 3 – STORMWATER MANGEMENT REQUIREMENTS
B. Select Source Controls
Source controls reduce the volume of runoff generated onsite, encourage infiltration and evapotranspiration,
and prevent pollutants from entering the drainage system. Non-structural BMPs are used for this purpose.
Maximize the use of non-structural BMPs as the most effective option for controlling stormwater to meet
sensitive area protection requirements and reduce the size of site runoff controls.

C. Size Runoff Controls
After source controls have been maximized, site runoff controls are typically needed to manage the
additional post-development stormwater runoff. Determine the standards applicable to the site to properly
size runoff controls. Minimum required stormwater standards are summarized in Table 1.

D. Confirm an Adequate Outlet
Once all onsite source and runoff controls have been implemented, excess runoff can be discharged offsite.
The design criteria specified in this manual is generally protective of the receiving waterbody. However, an
adequate outlet must always be identified downstream of the development to receive the design rate,
volume, and concentration of the post-development site runoff. Discharge from the site, including discharge
from emergency overflow spillways and pipes, must not cause adverse impact to downstream property or
infrastructure (refer to Part 2 section “Stormwater Discharge”).

E. Select Best Management Practices (BMPs)
Select appropriate BMPs to meet minimum required pollutant reduction, volume, and peak rate requirements.
A list of common BMPs and their treatment ability is given in Table 3. The BMPs selected must be
designed in accordance with the calculation methods and design criteria provided in this manual. BMPs
proposed for use, but not included in this manual, will be evaluated on an individual basis.

I.        SOILS INVESTIGATION
A. Qualifications
Soils investigation by a qualified geotechnical consultant is required for retention and detention basins, infiltration
practices, bioretention/rain gardens, constructed filters, planter boxes, and pervious pavement to determine the
site soil infiltration characteristics and groundwater level. The geotechnical consultant shall be a professional
engineer, soil scientist, or professional geologist.

B. Background Evaluation
An initial feasibility investigation shall be conducted to screen proposed BMP sites. The investigation involves
review of the following resources:
     1.    Soil Survey prepared by the NRCS and USDA Hydrologic Soil Group (HSG) classifications.
     2.    Existing soil borings, wells, or geotechnical report on the site.
     3.    Onsite septic percolation testing.
     4.    Cyclical groundwater levels http://waterdata.usgs.gov/mi/nwis/gw

C. Test Pit/Soil Boring Requirements
A test pit (excavated trench) or soil boring shall be used for geotechnical investigation. Test pits may typically be
selected for shallower investigations in locations where groundwater is sufficiently low.
The number of test pits or soil borings will vary depending on site conditions and the proposed development. The
minimum number of test pits or soil borings shall be determined from Table 4.
Additional tests may be requested based on local conditions and initial findings (e.g., large variability in soil type,
high groundwater table).

                                              PART 4 – STORMWATER DESIGN CRITERIA
Excavate a test pit or soil boring in the location of the proposed BMP. The following conditions shall be noted and
described, referenced from a top-of-ground elevation:
    1. Depth to groundwater recorded during initial digging or drilling, and again upon completion of the
       excavation.
    2. Depth to bedrock or hardpan.
    3. Depth and thickness of each soil horizon including the presence of mottling.
    4. Unified Soil Classification System for all soil horizons. USDA soil texture classification when required.
Test pit reports and soil boring logs shall include the date(s) data was collected and the location referenced to a
site plan.

D. Highest Known Groundwater Elevation
The highest known groundwater elevation shall be determined by adjusting the measured groundwater elevation
using indicators such as soil mottling and regional water level data. It should also take into consideration local
conditions that may be temporarily altering water levels at the time of measurement. Such conditions could
include, but not be limited to dewatering, irrigation well or large quantity withdrawals in the area, or areas of
groundwater infiltration (such as a nearby retention basin).

E. Field Permeability Testing
Field permeability testing is generally not required but may be performed to determine a design infiltration rate.
The City reserves the right to request that field permeability testing be performed. Field permeability testing
must be conducted for questionable soils before the alternative approach for channel protection will be
considered.
Acceptable field tests include:
    1. Infiltration Rate of Soils in Field Using Double-Ring Infiltrometers (ASTM D3385).
    2. Modified double-ring infiltration testing, using smaller diameter metal or plastic casings, where bore hole
       is required to reach design depth. The “Methodology for double-ring infiltrometer field test” outlined on
       page 440 in Appendix E of the Low Impact Development Manual for Michigan (SEMCOG, 2008) shall be
       followed for each test.
Laboratory tests are not allowed.
The minimum number of field permeability tests shall be determined from Table 4. The City reserves the
right to request additional field permeability tests be performed.
Tests shall be conducted in the location of the proposed BMP at the proposed bottom elevation. An alternate
testing depth may be allowed if material is identical, and groundwater is not an issue.
Tests shall not be conducted in the rain or within 24 hours of significant rainfall events (>0.5 inch) or when the
ground is frozen.
Test reports shall include the date(s) data was collected and the location referenced to a site plan.
F. Design Infiltration Rates
The procedure used to determine a design infiltration rate is summarized in Table 5. The resulting design
infiltration rate shall be the limiting value of the underlying soil or filter media/top dressing.

The infiltration rate determined from field permeability testing shall be divided by 2 to calculate the design
infiltration rate, up to a maximum design infiltration rate of 10 inches per hour. The least permeable soil horizon
within 4 feet below the proposed BMP bottom elevation shall be used to determine the design infiltration rate.
Where field permeability testing is not performed, and for all stormwater BMPs used for flood control, the
design infiltration rates provided in Table 6 shall be used to calculate the storage volume and minimum
infiltration area of the BMP necessary to drain in the allotted drawdown time.
Note: A conservative value for the infiltration rate is used for retention basins due to the high probability for
diminished performance due to clogging and the risk of failure.
When a filter material is used, or several materials are blended together in a homogenous mixture, the hydraulic
conductivities provided in Table 14 shall be used to calculate the design infiltration rate through the filter
media/top dressing placed in retentive BMPs.

         in Table D.13.1.


Table 6 provides design values of the infiltration rate and effective water capacity (void ratio) for soils based on
their textural classification. Soil textural classes correspond to the USDA Soil Textural Triangle shown in Figure 1.
Note: Infiltration is the process by which water on the ground surface enters the soil. Infiltration rate is a measure
of the rate at which soil is able to absorb rainfall or irrigation in inches per hour. The rate decreases as the soil

becomes saturated. The design infiltration rate assumes saturated conditions and closely approximates the
hydraulic conductivity (typically given in feet per day) of the near-surface soil.
Note: The effective water capacity of a soil is the fraction of the void spaces available for water storage
measured in inches per inch.

G. Minimum Allowable Infiltration Rate
Soil textures with design infiltration rates less than 0.24 inches per hour are deemed not suitable for
infiltration BMPs.
Soils with design infiltration rates between 0.24 and 0.50 inches per hour may be used for LID and Small Site BMPs
if suitable supplemental measures are included in the design. Supplemental measures may include subsoil
amendment, underdrain placed at the top of the storage bed layer, or placement of wick drains.

 II.      CALCULATION METHODOLOGY
  The Rational Method and the NRCS Runoff Curve Number Method are typically used to calculate
  stormwater runoff, peak discharges, and runoff volumes for design of stormwater conveyance and storage
  systems.
  The NRCS Method is presently the only acceptable method to calculate the channel protection volume.
  The Small Storm Hydrology Method is used to calculate runoff volumes from the smaller rainfall amounts used
  for water quality treatment.

  A. Calculating Runoff
       1. Rational Method
            The Rational Method may be used to calculate stormwater runoff volumes and peak discharges to
            size conveyance and storage systems for contributing drainage areas of 40 acres or less. The peak
            runoff rate is given by the equation:



         where:
         Q = peak runoff rate (cubic feet per second).
         C = weighted runoff coefficient of the drainage area.
         I    = average rainfall intensity for a storm with a duration equal to the time
                  of-concentration of the drainage area (inches per hour). Use rainfall amounts from
                  Table 11 and divide by the duration in hours to obtain the average rainfall intensity (I).
         A = drainage area (acres).
       Runoff coefficients shall be selected from Table 7. Lawns and Open reflect average slopes (2% to 7%).
       Subtract 0.05 for flat pervious slopes (0% to 7%). Add 0.05 for steep pervious slopes (over 7%).9

Time of concentration for the Rational Method is the sum of overland flow and channel flow. A minimum
of 15 minutes shall be used.
Overland flow time may be calculated using the following formula:




    where:
    to = time of overland flow (minutes)
    L   = length (feet); the distance from the extremity of the subcatchment area in a
           direction parallel to the slope until a defined channel is reached. Overland flow
           will become channel flow within 1,200 feet in almost all cases*

   The time-of-concentration is then:



                           where:
                           Tc =     time-of-concentration (minutes)
                           to =     time of overland flow (minutes)
                           Lc =     length of channelized flow (feet)
                           V   =    velocity of channelized flow (feet per second)
                           60 =     factor to convert seconds to minutes

2. Runoff Curve Number Method
   The Runoff Curve Number Method developed by the NRCS may be used to calculate stormwater runoff
   volumes and peak discharges to size conveyance and storage systems. This method must be used when
   it is necessary to calculate runoff volumes for channel protection. The formulas are as follows:




                    where:
                      Qv     = surface runoff (inches). Note: Qv=0 if P ≤ 0.2S
                      P      = rainfall (inches)
                      S      = potential maximum retention after runoff begins (inches)
                    and where:




   Surface runoff (Qv) is calculated separately for each land use and soil type combination. Total runoff
   volume can then be calculated by the formula:




                    where:
                    Vt     =   total runoff volume of the design storm (cubic feet)
                    Qv     =   surface runoff for the ith land use (inches)
                    A      =   contributing area associated with the ith land use (acres)
                    3630   =   factor to convert acre-inches to cubic feet

   Curve Number (CN) values are taken from NRCS TR-55 and provided in Table 9.
   The “Water” cover type shall be used for detention/retention basins with a permanent pool or surface
   water temporarily ponded during the rain event. The “Meadow” or “Open spaces” cover type may be
   used for vegetative BMPs, including those that temporarily pond surface water, to receive credit for
   channel protection.
   Peak Discharge
   The LGROW Design Spreadsheet, the DEQ procedure outlined in “Computing Flood Discharges for Small,
   Ungaged Watersheds” by Richard Sorrell, or computer software such as NRCS WinTR-55 may be used to
   calculate peak stormwater runoff rates.

                                             PART 4 – STORMWATER DESIGN CRITERIA
A Michigan Unit Hydrograph is used in the LGROW Design Spreadsheet, the DEQ small ungaged watershed
spreadsheet, and can be input into WinTR-55. The ordinates for the Michigan Unit Hydrograph for TR-55
are: [0.0, 0.5, 1.0, 0.8, 0.6, 0.4, 0.2 and 0.0].
Note: Using the standard NRCS unit hydrograph will overestimate peak runoff rates by 30 to 50 percent
or more.

Time-of-concentration for the Runoff Curve Number Method shall be calculated using NRCS TR-55 methodology
as outlined below. A minimum of 0.1 hour (6 minutes) shall be used.


The flow path is split into three          where:                                sections – sheet flow, shallow
concentrated flow, and open                    = slope (feet/foot)               channel flow. The travel time is
computed for each flow regime.             v   = velocity (feet per second)      The time-of-concentration is then
the sum of the travel times:




 (1) For sheet flow the travel time (t1) in hours is given as:




                        where:
                          n =      Manning’s roughness coefficient (from TR-55 Table 3-1)
                          L    =   flow length (feet)
                          P2 =     2-year, 24-hour precipitation depth (from Table 11)
                          s    =   slope (feet/foot)

(2) Shallow concentrated flow velocities are calculated for paved and unpaved surfaces. The velocities are
given as:




The flow length (feet) is then divided by the velocity (feet per second) and a conversion factor of 3600 to obtain
travel time (t2) in hours:Open channel flow uses




(3) Manning’s equation to calculate the velocity based on slope, flow area, and wetted perimeter (refer to
Equation 4.3). The flow length (feet) is then divided by the velocity (feet per second) to obtain travel time (t3) in
hours (refer to Equation 4.11).

BMP Residence Time
BMP residence time shall be calculated as the storage volume divided by the 10-year peak inflow rate.

3.   Small Storm Hydrology Method
The Small Storm Hydrology Method is used to calculate the water quality treatment volume. The method was
developed to estimate the runoff volume from urban land uses for relatively small storm events where the
Rational and NRCS Methods prove less accurate. Water quality volume is calculated by the formula:




                where:
                Vwq = minimum required water quality volume (cubic feet)
                A      = area (acres); the developed portion of the site, both impervious and
                         pervious, not receiving treatment with a non-structural BMP
                Rv     = area-weighted volumetric runoff coefficient (from Table 10)
                1      = 90% non-exceedance storm rainfall amount (inches)
                3630 = factor to convert acre-inches to cubic feet

 Note: The Volumetric Runoff Coefficients (Rv) provided in Table 10 are similar to the Rational runoff
 coefficient but are exclusive to the rainfall amount (1-inch).

The rainfall duration-frequency table provided in Table 11 shall be used with the Rational Method to determine
rainfall intensity for rainfall duration equal to the time-of-concentration. Divide the rainfall amount by the
duration in hours to obtain the rainfall intensity.
The 24-hour rainfall amounts provided in Table 11 shall be used with the Runoff Curve Number Method.
An MSE4 rainfall distribution shall be used when a unit hydrograph approach is used (e.g., WinTR-55 computer
program).

C. Calculating Storage Volumes and Release Rates
  1. Water Quality
     Treatment of the runoff generated from one inch of rain (the 90% annual nonexceedance storm) over
     the developed portion of the site is required. Water quality volume is calculated using the Small
     Storm Hydrology Method.
     A 1-year frequency rainfall may be used with the time-of-concentration of the contributing drainage area
     to calculate the peak flow rate for sizing diversion structures and treatment BMPs.
     Note: A 1-inch, 1-hour rainfall has approximately a 1-year frequency of occurrence. The use of a constant
     rainfall frequency allows for reasonable sizing of infrastructure for drainage areas with times-of-
     concentration less than 1 hour, since 1-inch of rain over these shorter durations results in high intensities
     and rainfall frequencies on the order of those used for flood control.
     Calculation of the TSS removal efficiency for BMPs in a series is given in Part 4 section “TSS Accounting.”
  2. Pretreatment
     Pretreatment volume may be included in the total water quality volume, and is calculated as:



                      where:
                      Vpt = minimum required pretreatment volume (cubic feet)
                      Vwq = water quality volume (cubic feet)
  3. Channel Protection
     (1) Retention
         Channel protection consists of retaining onsite the net increase in runoff volume between pre-
         development and post-development conditions for a 2-year, 24-hour storm using the Runoff
         Curve Number Method. Channel protection volume is calculated with the following equation:



            where:
            Vcp    = minimum required channel protection volume (cubic feet)
            Vtpost = total runoff volume of the 2-year, 24-hour storm for post-development
                     conditions
            Vtpre  = total runoff volume of the 2-year, 24-hour storm for pre-development
                     conditions


         The “Open Spaces” cover type in “fair” hydrologic condition shall be used for existing impervious
         surfaces. The “Woods” cover type in “good” hydrologic condition shall be used for existing woods.
         The “Meadow” cover type shall be used for all other existing land covers.




                                                      36
                                      PART 4 – STORMWATER DESIGN CRITERIA

(2) Extended Detention
   The storage volume of an extended detention basin shall be sized for that part of the 2-year volume
   difference not met by retention, with a maximum release rate that results in a 24-hour detention
   time.

   The peak discharge for a 24-hour detention time may be calculated assuming triangular inflow and
   outflow hydrographs with a lag between the peaks of 24 hours. If the inflow peak occurs 12 hours into
   the 24-hour inflow hydrograph, the outflow peak should occur 36 hours into a 72-hour outflow
   hydrograph as shown in Figure 2. The extended detention peak discharge can then be computed with
   the following equation:



          where:
          QED        =   peak extended detention release rate (cubic feet per second)
          Vcp        =   total channel protection volume required (cubic feet)
          Vret       =   channel protection volume met by retention (cubic feet)
          36*3600    =   half of the base time of outflow hydrograph (seconds)

   The 2-year peak discharge after extended detention (QED) must be equal to or less than the existing
   1-year peak discharge. (Exceptions may be made for HSG A, where extended detention has been
   approved due to site constraints, but existing runoff is zero.) If the 1-year peak discharge limit is not
   met, the total channel protection volume provided must be increased to reduce the required
   extended detention volume. Simply using a lower extended detention release rate will violate the
   72-hour drawdown time requirement.

        4. Flood Control
            (1) Detention
                Detention of the 25-year rainfall event with a maximum allowable release rate of 0.13 cfs per acre is
                required, unless an exception is allowed.

                a. Rational Method for Detention
                      If the Rational Method is used, the minimum required storage volume shall be calculated by the
                      “Modified Chicago” Method.

                      The calculated storage volume shall be multiplied by 1.25 to obtain the minimum required storage
                      volume.
                      Note: This additional adjustment is necessary since the Modified Chicago Method tends to
                      underestimate the storage volume when compared to pond routing, particularly for short
                      times-of-concentrations (15 to 30 minutes)10.

                b. Runoff Curve Number Method for Detention
                      If the Runoff Curve Number Method is used, the minimum required storage volume shall be
                      determined through routing using the LGROW Design Spreadsheet, or may be calculated by the
                      formula:




                       where:
                       Vfc      = minimum required storage volume for flood control (cubic feet)
                       Qp       = peak runoff rate (cubic feet per second)
                       Qout     = maximum allowable peak discharge (cubic feet per second)
                       Vt       = total post-development runoff volume for the 25-year, 24-hour
                                  storm (cubic feet)
                       Vbmp     = volume (storage only) provided by upstream retentive BMPs (cubic
                                  feet)


                 Note: This formula provides a conservative approximation of the required storage volume.

                                      PART 4 – STORMWATER DESIGN CRITERIA
(2) Retention
   Retention basins shall be sized for the 25-year, 24-hour rainfall event.
   a. Rational Method for Retention
       If the Rational Method is used, the minimum required storage volume shall be calculated by the
       “Modified Chicago” Method.
       The calculated storage volume shall be multiplied by 1.25 to obtain the minimum required
       storage volume.
       The discharge or exfiltration rate into the soil from the retention basin shall be calculated at:


       where:
       Qout   =   discharge rate (cubic feet per second)
       A      =   infiltration area (square feet)
       i      =    design infiltration rate (inches per hour)
       12     =   factor to convert inches to feet
       3600 =     factor to convert hours to seconds


   b. Runoff Curve Number Method for Retention
       If the Runoff Curve Number Method is used, the minimum required storage volume shall be
       calculated by the formula:


      where:
      Vfc    = minimum required storage volume for flood control (cubic feet)
      Vt     = total post-development runoff volume for the 25-year, 24-hour storm
               (cubic feet)
      Vinf   = infiltrating volume (cubic feet), calculated the same as indicated in
               “Retentive BMPs Sized for Channel Protection or Water Quality”




                                                39
                                                 PART 4 – STORMWATER DESIGN CRITERIA
     5. Retentive BMPs Sized for Channel Protection or Water Quality
         The BMP volume (Vbmp) credited towards meeting the channel protection or water quality volume is the
         storage volume of the BMP plus the volume infiltrated by the BMP during the infiltration time.
         The infiltrating volume shall be calculated with an iterative process using the following equations, or with
         the LGROW Design Spreadsheet, which incorporates these equations. The infiltrating volume is calculated
         as:




The infiltration time shall be calculated by the formula:




                  where:
                  Vinf =
                       infiltrating volume (cubic feet)
                  i    =
                       design infiltration rate (inches per hour)
                  A =  infiltration area (square feet)
                  tinf =
                       infiltration time (hours); the period when the BMP is receiving runoff and
                       capable of infiltrating at the design rate
                  12 = factor to convert inches to feet

Note: Based on extensive computer modelling, the infiltration time is found to be a function of the drain time
through the BMP. An empirical formula was developed to model this function for drain times between 0 and 72
hours. This equation is not valid for drain times greater than 72 hours.

The drain time through the BMP is calculated as:


                                  where:
                                  td   =   BMP drain time (hours)
                                  VS   =   storage volume of the BMP (cubic feet)
                                  i    =   design infiltration rate (inches per hour)
                                  A    =   infiltration area (square feet)
                                  12 =     factor to convert inches to feet

 D. Groundwater Mounding
 A spreadsheet developed by the USGS is recommended to calculate the extent of groundwater mounding beneath
 infiltration BMPs. The USGS Scientific Investigations Report 2010–5102 “Simulation of Groundwater Mounding
 Beneath Hypothetical Stormwater Infiltration Basins,” may be used with the accompanying spreadsheet, which
 solves the Hantush (1967) equation to predict the extent of groundwater mounding based on user-specified site
 conditions. Other finite-difference groundwater flow models such as USGS MODFLOW are also acceptable.


 E. Computing Tools
 Hydrologic and hydraulic calculations can be performed using a variety of customized spreadsheets and computer
 software. The LGROW Design Spreadsheet shall be used to determine minimum required storage and treatment
                                                       40
                                                PART 4 – STORMWATER DESIGN CRITERIA
volumes. Results of computer models that use detailed routing methods to optimize storage volume may be
considered for more complex situations. Accompanying design calculations may include hand calculations or
spreadsheets using the formulas specified in this manual, and computer models with submittal of clear and
complete input and output.


F. LGROW Design Spreadsheet
The LGROW Design Spreadsheet is a Microsoft Excel spreadsheet application developed for Design and Review
Engineers to show compliance with the stormwater standards. The spreadsheet allows the user to size BMPs in
series or in parallel but is not intended to be used for the complete design of BMPs. A copy of the spreadsheet
and tutorial is available from the City.
Runoff
The spreadsheet uses the Runoff Curve Number Method to compute runoff volumes by subcatchment. A tabular
TR-55 approach is used with a Michigan Unit Hydrograph to compute peak runoff rates. The spreadsheet can be
used to calculate the required channel protection volume and the flood control volume for both detention and
retention. The Small Storm Hydrology Method is used to calculate the required water quality volume.
The 24-hour rainfall amounts, and rainfall distribution specified in Part 4 section “Rainfall” are incorporated into
the spreadsheet. Time-of-concentration formulas from TR-55 are also incorporated into the spreadsheet to
calculate peak discharges. Output is graphed as hydrographs and summarized in tabular form for a range of rainfall
frequencies.
The spreadsheet allows the user to select non-structural and structural BMPs to meet required runoff rates and
volumes.
TSS Accounting
The spreadsheet can be used to calculate the TSS reduction for a series of BMPs. The TSS removal efficiencies for
the BMPs provided in Table 3 are used to demonstrate a TSS reduction of 80% or more. When BMPs are used in
series (i.e., a treatment train) to achieve the 80% reduction, the TSS removal efficiency of the treatment train is
calculated as:


where eTSS is the removal efficiency of the treatment train, and en is the removal efficiency for the nth BMP in the
chain of n BMPs. This calculation assumes all water entering the treatment train is passed through to the next
downstream BMP. The spreadsheet allows the user to calculate TSS reduction when either all or a portion of the
water quality volume is passed downstream.
BMPs used for water quality treatment can be classified as retentive or pass-through. Retentive BMPs (e.g.,
infiltration practice) retain and treat some or all of the water quality volume. Pass-through BMPs (e.g., catch basin)
treat all of the water entering and send this volume to the next BMP or subcatchment.
TSS accounting is done by tracking TSS through the subcatchments. In order to do this, it is assumed that one unit
of TSS is the mass of TSS carried by one cubic foot of the water quality volume. The effective removal efficiency is
the BMP removal efficiency multiplied by the portion of the water quality volume treated by the BMP. The TSS
removed for each BMP is the effective removal efficiency multiplied by the TSS remaining in the treatment train.
The TSS removal efficiency for the subcatchment and/or site is the sum the TSS removed by all BMPs divided by
the total TSS to be treated. The released water volume and the TSS remaining are both passed to the next
downstream subcatchment.

                                                PART 4 – STORMWATER DESIGN CRITERIA
Pond Routing
Detention storage volume for flood control is computed by numerically routing the hydrograph for the developed
site through a detention basin (pond). The steps in the process are as follows:
   1. The inflow hydrograph is interpolated from a collection of scaled hydrographs computed using TR-20 for
       various times-of-concentration and the ratio of initial abstract to total rainfall (Ia/P) values.
       This is similar to the tabular TR-55 approach. The hydrograph collection was generated using the
       Michigan specific dimensionless unit hydrograph.
   2. Structural BMP volumes are removed from the front of the hydrograph, effectively reducing the required
       flood control volume. The resulting hydrograph does not start until all retention volume is satisfied.
   3. The inflow hydrograph adjusted for structural BMPs is routed through a detention pond model using the
       Modified Puls Method (see Section 8.4.8 of the MDOT Drainage Manual). The pond is assumed to be
       prismatic and defined by a bottom area, side slope, and orifice diameter. Pond routing is the calculation
       of the outflow hydrograph given the inflow hydrograph and pond characteristics. This calculation is based
       on the continuity equation written in differential form:




       where V is the volume of water in storage in the pond at time t, I is the inflow at time t, and Q is the
       outflow at time t. To calculate the outflow hydrograph, a finite difference method approximation of the
       continuity equation is used. This allows Q to be calculated as a time series:




       where Δt is the time step, i+1 refers to the present time and i refers to a time Δt earlier. At time i+1
       everything on the right-hand side of the equation is known, allowing the value of the left-hand side to be




       determined. Since V and Q are both functions of the pond depth, H,                           given the pond
       characteristics a table can be constructed. This table is then used to find the pond depth at time i+1. Given
       this pond depth, the storage volume, V, and outflow, Q, can also be computed at time i+1. The
       calculation can then proceed to the remaining time steps resulting in the outflow hydrograph.
   4. The pond model characteristics include bottom area, side slope, and orifice diameter. The spreadsheet
       computes the required orifice diameter to produce the desired peak discharge at an arbitrary depth of
       5 feet. The sides are conservatively assumed to be vertical.
   5. The spreadsheet runs a macro that iteratively adjusts the bottom area until the desired peak discharge
       and storage depth are met.
Application
The LGROW Design Spreadsheet can assist the Design Engineer in applying the correct land uses and Curve
Numbers in calculating channel protection volume, accounting for travel time through BMPs, accounting for total
TSS reduction from a series of BMPs, and quickly evaluating a variety of stormwater management options for a
range of rainfall frequencies.

Design calculations submitted using the LGROW Design Spreadsheet can help to expedite the review process
because reviewing engineers are familiar with the spreadsheet and can more quickly check for compliance with
stormwater standards.
The Stormwater Worksheet is incorporated into the LGROW Design Spreadsheet and need not be submitted
separately if the spreadsheet is used.

                                         For small sites, individual trees can receive a credit of
                                         800 square feet per tree, counted as woods in “good” condition.1

           Note: Trees in minimal disturbance areas receive a larger area credit than trees planted under “Native
           Revegetation” due to the assumption that the existing trees will typically be larger and more mature
           than planted trees at the time of site plan submittal and during ensuing years.

      Note: Trees in minimal disturbance areas receive a larger area credit than trees planted under “Native
      Revegetation” due to the assumption that the existing trees will typically be larger and more mature
      than planted trees at the time of site plan submittal and during ensuing years.
  2. Criteria
     a. Identify native revegetation areas on site plan and construction drawings.
     b. Native revegetation areas must be protected by having the limits delineated/flagged/fenced in the
        field. Notes to this effect must be included on construction drawings.
     c. Standards shall consist of:
        (1) Variable width depending on topography, minimum 25-foot width (Zone 1).
        (2) Native revegetation selected from the Low Impact Development Manual for Michigan (SEMCOG,
             2008), Appendix C.
     d. Areas receiving credit must be located on the development project.

                                   “good” condition.

                                     The following weighted CNs can be assigned to the
                                     disconnected impervious area. They assume a pervious area
                                     twice the size of the impervious area.

          Water Quality:             Exempt from water quality criteria.
  2. Criteria
     a. Stormwater from rooftops and other impervious areas is considered disconnected if it is routed to a
        stabilized vegetated area, or an onsite depression storage area that meets the following criteria:
        (1) Pervious area is not a structural BMP that must be designed to treat the runoff from the
               impervious surface.
        (2) Impervious area must be limited to 1,000 square feet per discharge point.
        (3) Roof downspouts and curb cuts must be at least 10 feet away from the nearest connected
               impervious surface to discourage “re-connections.”
        (4) Disconnection in less permeable soils (HSGs C and D) may require the use of dry wells, french
               drains, or other temporary storage device to compensate for poor infiltration capability if
               ponding of water for extended period of time becomes problematic.
        (5) For disconnects to stabilized vegetated areas:
               (a.) Size of disconnect area shall be twice the size of the contributing impervious area.
               (b.) Length of disconnect area must be at least the length of the flow path of the contributing
                     impervious area (maximum 75 feet).
               (c.) Slope of disconnect area must be no greater than 5%.
               (d.) Disconnect area may be a “minimal disturbance area.”
        (6) Disconnection must ensure no basement seepage.
        (7) Identify disconnect areas on site plan and construction drawings.

              Rate Reduction:      None.
               Water Quality:      Count volume routed through catch basin.

  2. Design Requirements
     a. Sizing and Configuration
        (1) Storm sewer shall be designed to convey the peak discharge from a 10-year rainfall event.
        (2) A dual or redundant storm sewer may be required to convey the peak discharge from a 100-year
            rainfall event if acceptable overland flow routes do not exist (refer to Part 3 section “Flood
            Control”).
        (3) Design velocities, capacities, and friction losses shall be based on Manning's equation:




                                   where:
                                   Q =      discharge (cubic feet per second)
                                   A =      wetted area (square feet)
                                   R =      hydraulic radius (feet)
                                   S   =    slope (feet per foot)
                                   n =      Manning’s roughness coefficient


        (4) Manning's coefficients for closed conduit are included in Table 12.
        (5) Acceptable slopes for circular pipe ("n" = 0.013) are included in Table 13. Minimum and maximum
            grade for other Manning's n values must be calculated based on allowable minimum and
            maximum velocities (V).
        (6) As a general rule, the storm sewer system shall be designed without surcharging. Where this is
            not possible, surcharging may be allowed to one foot below the top of casting. However,
            minor losses must be considered in hydraulic grade line calculations.
        (7) Storm sewer pipe shall have a minimum diameter of 12 inches. Smaller pipe may be approved for
            private systems.
        (8) The minimum depth of cover shall be 24 inches from grade to the top of pipe.


                                                      50

  (9) Restricted conveyance systems designed to create backflow into stormwater storage facilities are
      not permitted. A storm sewer line shall not be used as both an inlet and outlet line to a stormwater
      storage facility.

        direction of flow.
c. Manholes and Catch Basins
    (1) Manhole spacing shall not exceed 400 feet for sewers less than 42 inches in diameter and 600 feet
        for larger sewers.
    (2) Manholes shall be placed at all changes in pipe direction, slope, pipe size, all inlet connection
        locations, and at the upper end of the storm sewer.
    (3) Where possible, pipe inverts at junctions shall be designed to minimize junction losses (match
        0.8 points of pipe diameters).
    (4) Minimum inside diameter of all manholes, catch basins, and inlet structures shall be 48 inches,
        except that a 24-inch diameter structure may be allowed with a single 12-inch outlet pipe.
    (5) All structures receiving direct surface water runoff shall have a sump not less than 24 inches deep.
    (6) Catch basins shall be placed at low points of streets and yards. Spacing and/or number of inlet
        structures required to accommodate the design flows in streets, private drives, and parking areas
        shall be provided based on inlet capacity with no ponding occurring during a 10-year storm, and
        the following additional stipulations:
        (a.)   No more than 300 feet of pavement surface drainage will be allowed. No more than
               200 feet of surface drainage will be allowed for grades exceeding 4%.
        (b.)   Consideration shall be given to pedestrian crossings when siting catch basins in
               intersections. Catch basins shall be placed upstream of pedestrian crossings when practical.

            orifice configuration must be wrapped with hard wire mesh with an appropriate opening size
            to prevent any stone from passing through the orifice. The 3-inch stone must be placed
            immediately adjacent to the riser pipe with the 1-inch stone covering the larger stone. The
            gravel jacket must extend sufficiently above all orifice patterns.

                C = coefficient of discharge (varies from 2.6 to 3.3)
                m = Horizontal component of side slope
                L   = length of spillway crest (feet)

      Application:                     Practical for a wide range of applications including large sites.
                                       Not recommended for regional use without supplemental
                                       measures and provisions for a positive outlet.
      Types:                           Dry Basin; Wet Pond.
      Pretreatment Required:           Yes.
      Maintenance Plan:                Yes.
      Calculation Credits:
                 Volume Reduction:     Count volume stored and infiltrated.
                    Rate Reduction:    Designed for flood control: 100%.
                     Water Quality:    Count volume stored and infiltrated.
  2. Sizing Calculations
     a. Calculate the required storage volume for flood control (refer to Part 4 section “Calculating Storage
        Volumes and Release Rates, Flood Control, Retention”).
     b. Calculate the minimum infiltration area required to drain the required storage volume in the specified
        drawdown time using the design infiltration rate (refer to Part 4 section “Design Infiltration Rates”).




                           where:
                           A =      minimum infiltration area (square feet)
                           Vs =     storage volume (cubic feet)
                           i   =    design infiltration rate (inches per hour)
                           td =     maximum allowable drawdown time (hours)
                           2        factor to convert inches to feet

     c. Drawdown time shall be no more than 72 hours.
     d. The infiltration area shall be defined as the bottom of the basin, or the horizontal projection of the
        side slopes up to half of the design water depth above a permanent pool.
     e. Where channel protection and water quality treatment are provided through upstream retention
        BMPs, these volumes may be subtracted from the total inflow volume. If provided in the same
        retention basin, channel protection and water quality volumes are included in the flood control
        volume.
     f.   Pretreatment: Size forebay(s) for the pretreatment volume (refer to Part 4 section “Calculating
          Storage Volumes and Release Rates”). Regional retention basins may require spill containment,
          forebays sized for the full water quality volume, additional pretreatment volume, or other measures
          to reduce the potential for groundwater contamination and protect the infiltration capacity of the
          BMP.
     g. Retention basins without an acceptable surface water overflow route shall be designed for 2 times
        the required flood control volume.

         (a.) Leaching basins, infiltration trench, or wick drains placed in the bottom of the basin.
         (b.) Valved outlet to drain basin.
         (c.) Conversion to a wet basin with sufficient storage volume provided above the permanent pool
              for reduced infiltration area.

      Application:                      Contributing drainage areas with sheet flow surface runoff.
      Types:                            Turf grass; other dense herbaceous groundcover vegetation.
      Pretreatment Required:            No. This BMP provides pretreatment.
      Maintenance Plan:                 Yes.
      Calculation Credits:
                 Volume Reduction:      None.
                    Rate Reduction:     Adjust time-of-concentration.
                     Water Quality:     Count volume routed through BMP.
  2. Sizing Calculations
     a. Used for Pretreatment
         (1) Provide a 10- f o o t minimum sheet flow length at a maximum slope of 2% with an
             impervious approach length no greater than 3.5 times the filter strip length, up to a
             maximum approach length of 75 feet.
         (2) Provide a 15-foot minimum sheet flow length for slopes between 2% and 6% with an impervious
             approach length no greater than 3 times the filter strip length, up to a maximum approach length
             of 75 feet.
     b. Used for Water Quality
         (1) Calculate the minimum required filter strip area by the equation:




                            where:
                            Afs = area of filter strip (square feet)
                            A   = contributing drainage area (square feet)

         Note: This equates to a loading ratio of 0.17 from the contributing drainage area (both impervious
         and pervious surfaces).
         (2) Calculate minimum required longitudinal length based on slope and type of vegetation using the
             graphs in Figures 4a through 4d.

  3. Design Requirements
     a. Siting
         (1) Maximum upstream drainage area shall generally be 100 feet impervious or 200 feet pervious.
     b. Configuration
         (1) The upstream edge of the filter strip shall be level and at an elevation at least one inch below
             the adjacent pavement.
         (2) A level spreader may also be required to evenly distribute flow across filter strip.

(3) Slopes shall range from a minimum of 1% to a maximum of 8%. Optimal slopes range from 2%
    to 6%.
(4) The maximum lateral slope shall be 1%.
(5) Berms and curbs may be installed along the sides of the filter strip parallel to the direction of flow
    to prohibit runoff from laterally bypassing the filter strip.

APPENDIX 1 – WATERSHED POLICY
  •   Ruddiman Creek Watershed
Ruddiman Creek Watershed
A. BACKGROUND AND PURPOSE
   The Ruddiman Creek watershed is located in portions of the Cities of City of Muskegon, Norton Shores,
   Roosevelt Park and City of Muskegon Heights. Ruddiman Creek discharges to City of Muskegon Lake and is
   located with the City of Muskegon Lake Area of Concern (AOC). Ruddiman Creek is presently not meeting its
   designated uses for wildlife, other indigenous aquatic life, and as a warm water fishery due primarily to a
   poor macroinvertebrate community. Ruddiman Creek is also not meeting its designated uses for fish
   consumption, and total and partial body contact.




   In 2010, the Grand Valley State University (GVSU) Annis Water Resources Institute (AWRI) received a FY 2010
   Great Lakes Restoration Initiative (GLRI) grant to conduct studies to support a Ruddiman Creek
   Implementation-Ready Total Maximum Daily Load (TMDL) for biota to address the wildlife, other indigenous
   aquatic life, and warmwater fishery designated uses.
   Conclusions are taken from the final report “Studies to Support an Implementation-Ready TMDL for Ruddiman
   Creek” dated February 2013. The technical information included in the report was used to support the
   Michigan Department of Environmental Quality (DEQ) in the development of a TMDL for biota.
   The poor macroinvertebrate community was attributed primarily to the flashiness of the watershed hydrology
   (Nederveld, 2009); therefore, a hydrologic surrogate was used for the biota TMDL. The relationship between
   flashiness and Directly Connected Impervious Area (DCIA) was used to develop TMDL targets in terms of
   percent reduction in DCIA needed to reduce flashiness and improve biota.
   A spreadsheet application referred to as a Scoping Tool was developed to relate P-51 macroinvertebrate
   scores with a Richards-Baker Flashiness Index (FI). The Scoping Tool was also used to relate changes in the
   amount of DCIA to changes in the FI by subwatershed. A BMP inventory sheet is included to account for
   progress made towards meeting the TMDL.
   The purpose of the design criteria included in this section is to account for reductions in DCIA to reduce the
   flashiness of stormwater runoff associated with urbanization to meet TMDL targets and improve biota in
   Ruddiman Creek.
B. CONCLUSIONS
   The Ruddiman Creek watershed is highly urbanized; impervious cover from developed land is over 50%, far
   exceeding the 10-15% threshold that has been suggested to cause biotic impairment in streams (Wang et al.
   2001). As a consequence, the tributaries in the Ruddiman Creek watershed are subject to altered hydrology,
   characterized by high flashiness. The unnatural flow regime can physically dislodge benthic organisms;
   mobilize sediment, causing habitat impairment; and transport previously buried or sequestered
   contaminants, rendering them bioavailable to organisms (cf. Cooper et al. 2009; Johnson et al. 2011).
   In terms of sediment, the primary form of sediment transported by storm flows is suspended sediment.
   Monitoring indicated that all branches of Ruddiman Creek meet the “Good to Moderate” threshold (≤ 80
   mg/L) for annual mean suspended sediment concentrations (SSC) suggested by Alabaster and Lloyd (1982) for
   protection of fish communities. However, short term increases in SSC during storm events are much higher
   and may cause impacts to aquatic communities. Improvements in watershed hydrology resulting from BMPs
   are projected to reduce SSC by 25-50%.
C. TMDL
   A biota TMDL for Ruddiman Creek has not been accepted by the United States Environmental Protection
   Agency (EPA), and therefore has not been implemented by the DEQ. However, loading capacities identified in
   the study are still recommended to restore the identified designated uses. Loading capacities for each branch
   of Ruddiman Creek are summarized in Table 5.3 from the report:

      Branch              Current        Fraction DCIA      WLA + LA           MOS               LC
                        Percent DCIA       Reduced*
      Main                  21%               0.35            13.5%             1.2             12%
      North                 7.5%              0.52             3.6%             1.2             2.9%
      West                  16%             0.68               5.0%             1.2             2.8%
      DCIA = Directly Connected Impervious Area
      WLA = Waste Load Allocation (point sources)
      LA = Load Allocation (nonpoint sources) MOS
      = Margin of Safety
      LC = Load Capacity (the greatest amount of DCIA the watershed can support without violating the
      stream’s aquatic life criteria)
      *Modeling a Benchmark Scenario identified the reduction in DCIA needed to achieve reductions in
      FI resulting in minimum acceptable P51 macroinvertebrate scores.
D. DESIGN CRITERIA
   The following criteria shall apply for all new developments and redevelopments subject to review under these
   standards and located within the Ruddiman Creek watershed:
   1. Standard design criteria for water quality and channel protection with an emphasis on reducing DCIA. An
      increase in DCIA is not allowed. The design engineer must treat any additional DCIA so it is effectively
      “reduced.”
   2. DCIA is considered effectively “reduced” when:
      a. Impervious surfaces are physically removed and replaced with pervious surfaces.
      b. Impervious surfaces are disconnected from the storm sewer system by routing runoff to pervious area
         meeting minimum size, length, and slope requirements (e.g., a rain barrel with an overflow directed
         to yard, away from the storm sewer).
      c. Impervious surfaces are disconnected from the storm sewer system by routing runoff to an infiltration
         BMP sized for the channel protection volume.
      d. An underdrained LID BMP (e.g., rain garden, porous pavement, green roof) is engineered and
         implemented for channel protection and volume reduction with a hold time no less than 72 hours.
E. SCOPING TOOL
   For redevelopments (and new developments if applicable) impacting existing DCIA, the design engineer shall
   complete the BMP Inventory Sheet in the Scoping Tool spreadsheet application and submit this
   documentation with the design calculation package.

Hearing; Case 2022-26: Request to rezone the property at 398 Catawba Ave from R-3, Single Family
High Density Residential to B-4, General Business, by Gordon Painting and Pressure Washing, LLC.

SUMMARY

   1. The property is zoned R-3, High Density Single Family Residential.
   2. The commercial building on site is considered grandfathered and has been used by Gordon
      Painting for many years.
   3. The applicant would like to put an addition on to the building in order to start a power washing
      business alongside the painting business. However, non-conforming uses are only allowed to
      expand their buildings up to twenty-five percent.
   4. The property is adjacent to a commercial/industrial corridor.
   5. Staff had initially discussed rezoning the property to Light Industrial since it is adjacent to light
      industrial properties. However, these uses can be located in a General Business zone and will offer
      protection to the residential neighborhood that more intensive uses will not be able to be located
      there.
   6. Notice was sent to all properties within 300 feet. At the time of this writing, staff had not received
      any comments from the public.

Commission Meeting Date: October 25, 2022                               Title: Ordinance Amendment
                                                                        – Reduced Housing Unit Size
                                                                        Minimums – 2nd Reading

Submitted By: Mike Franzak                                              Department: Planning

Brief Summary: Staff-initiated request to amend section 2319 of the zoning ordinance to reduce the
minimum size requirements for single-family houses, rowhomes, duplexes and small multiplexes (up
to 6 units) from 850 sf of floor area to 550 sf (total) and to also change the minimum size requirements
for large multiplexes (6 units and above), mixed-use buildings and accessory dwelling units from 650
sf of floor area to 375 sf (total).

Detailed Summary & Background: A motion to recommend approval of the original request failed
by a 2-3 vote at the August 11 Planning Commission meeting. At the august 23 City Commission
meeting, staff requested to remove the item from the agenda in order to make some changes to
the proposal and bring back to Planning Commission. The proposal was amended and brought
back to the Planning Commission at their September 15 meeting, where they recommended
approval of the new amendments by a 6-1 vote.
The changes to the original amendment include requiring an additional 100 sf for each additional
bedroom; additional language stating that all units located in single-family residential districts must
comply with Section 400 of the zoning ordinance, which will prevent single-family houses from being
split into additional units. It should also be noted that the current minimum housing size is measured by
“floor area,” which is defined by the zoning ordinance as “the area in a dwelling unit included in the
determination of occupancy restrictions. It includes the sum of floor areas of bedrooms, and common
living areas. The floor area of storage areas and closet, basements without a second egress, attached
garages, breezeways, and enclosed and unenclosed porches shall be excluded.” Staff is proposing to
no longer use this method in determining the minimum size, but rather by measuring from the outside
wall of the unit.

Case 2022-22: Staff-initiated request to amend section 2319 of the zoning ordinance to reduce the minimum
size requirements for single-family houses, rowhomes, duplexes and small multiplexes (up to 6 units) from
850 sf of floor area to 550 sf (total) and to also change the minimum size requirements for large multiplexes
(6 units and above), mixed-use buildings and accessory dwelling units from 650 sf of floor area to 375 sf
(total).

SUMMARY

   1. This case was presented at the August 11 Planning Commission meeting. The board did not
      recommend approval of the amendments at the meeting. At the following City Commission meeting,
      staff requested to take the case back to the Planning Commission with some changes and
      clarification, to which the City Commission approved.
   2. Staff is now proposing to keep the requirement that an additional 100 sf is required for each
      additional bedroom.
   3. Staff has added that all units located in single-family residential districts must comply with Section
      400 of the zoning ordinance, which will prevent single-family houses from being split into additional
      units.
   4. For one and two family homes, staff has proposed the clause that states that if the house is less than
      850 sqft and is to be located on a lot that is large enough to split under the zoning regulations, it must
      be placed in such a fashion as to allow enough room to split the lot and create an additional buildable
      lot. This clause had previously been proposed for the for the mixed-use building section as well, but
      is not needed because these types of requirements are addressed elsewhere in the ordinance,
      specifically the form based code and multifamily sections of the code.
   5. It should be noted the current minimum housing size is measured by “floor area,” which is defined by
      the zoning ordinance as the area in a dwelling unit included in the determination of occupancy
      restrictions. It includes the sum of floor areas of bedrooms, and common living areas. The floor area
      of storage areas and closet, basements without a second egress, attached garages, breezeways, and
       enclosed and unenclosed porches shall be excluded. Staff is proposing to no longer use this method in
       determining the minimum size, but rather by measuring from the outside wall of the unit.

       Summary of the case from the precious meeting:

   6. In an effort to address housing affordability and to provide residents with a wide range of housing
       choices, staff is proposing to reduce the minimum housing size requirements listed in the Residential
       Design Criteria section of the zoning ordinance.
   7. Currently, single-family houses and duplexes are required to have a minimum living area (excluding
       all basement area) of 850 sqft for a one bedroom dwelling. For each bedroom thereafter, an additional
       100 sqft of living space is required.
   8. Living area is defined in the zoning ordinance as the area in a dwelling unit included in the
       determination of occupancy restrictions. It includes the sum of floor areas of bedrooms, and common
       living areas. The floor area of storage areas and closet, basements without a second egress, attached
       garages, breezeways, and enclosed and unenclosed porches shall be excluded.
   9. Staff is proposing to reduce the minimum size of single-family houses, rowhomes, duplexes and small
       multiplexes (up to 6 units) to 550 sqft total (excluding all basement area) per unit, measured by the
       outside dimensions of the building, not by using the “living area” definition in the zoning ordinance.
       There would also be a stipulation that structures under the current minimum size of 850 sqft, which are
       to be placed on large lots, must be placed on the property in a way as to leave room for a potential lot
       split, if the property is large enough to split under its zoning designation regulations.
   10. Staff is proposing to reduce the minimum size of apartment units in large multiplexes (6 units and
       above) and mixed-use buildings from 650 sqft of living space to 375 sqft total. The current size
       requirements are too large for developers to be able to provide traditional studio apartments.

Current ordinance excerpt:

   construction and may be done at a later date at the property owners discretion.
3. All buildings located in single family residential districts must comply with Section 400.2 of the zoning
   ordinance. Multiple family dwellings are only allowed in single-family residential districts if the home

   ordinance. Multiple family dwellings are only allowed in single-family residential districts if the home
   has already been altered with prior approval to allow for multiple dwellings. One-family dwellings may

All due diligence items have been completed and grant funding secured for portions of the road
addition to the Port City Industrial Park, necessitating minor additions to the original Purchase
Agreement for the development site.

Detailed Summary & Background:
City Staff have been working with the development team from Northern Biomedical Research for
most of the year on several critical details to move this project into construction, and we are
approaching a final closing date. DPW and Development Services staff have achieved a $630,000
Transportation Economic Development Fund Grant to help offset infrastructure costs to the
expansion to the industrial park, and timelines for this construction are reflected in the amendment.


We also have some remaining concrete millings and spoils from the deconstruction of the West
Shoreline Correctional Facility that will be reused in construction of the public and private assets in
the new section of the park, and this is referenced as well.

      A.    Grantor is the owner of certain real property located in the City of Muskegon,

                                          AGREEMENT

       NOW THEREFORE, for good and valuable consideration, the receipt and adequacy of
which is hereby acknowledged, the parties agree as follows:

        1.      Grant of Access Easement. Grantor hereby grants and conveys to Grantee, its
successors and assigns, a nonexclusive easement for pedestrian and vehicular ingress and egress
on, over and across the Grantor Property until the Road Extension is completed and open to the
public for vehicular travel. The Grantor Property may be used by Grantee, along with its agents,
lessees, contractors, subcontractors, and employees, for the purposes described above, including,
but not limited to, such use for ingress and egress of construction vehicles and heavy equipment
and machinery, and any related purpose. Grantee may, during the term of this Agreement, remove
trees and other vegetation within the easement area on the Grantor Property if Grantee determines
that such removal is necessary in connection with Grantee’s rights under this Agreement.

        Grantee acknowledges that access may be disrupted from time to time due to the
construction of the Road Extension. At times when access is disrupted, Grantor will provide
alternate access options to suit the needs of the Grantee.

       2.      Repair and Maintenance of Easement Area. Grantor shall maintain the Grantor
Property so as to afford continuous access and safe and unimpeded passage of vehicular and
pedestrian traffic on, over and across the Grantor Property. Any damage caused to any
improvements within the Grantor Property by the acts or neglects of the owner of the Grantor
Property or the Grantee Property, or by such owners’ agents, lessees, employees, contractors, or
subcontractors shall be repaired or replaced solely by such owner, at its sole cost and expense.

        3.      Indemnity. Grantee agrees to defend, indemnify, and save harmless Grantor from
and against any and all liability or claim thereof (including, but not limited to, reasonable attorney
fees and costs), whether for injury to persons, including death, or damage to property, which may
be imposed upon, incurred by or asserted against Grantor (i) arising in connection with or as a
direct or indirect result of any activity by Grantee, its employees, agents, lessees, contractors, or
subcontractors in, on or about the Grantor Property during the term of this Agreement; or (ii)
arising out of any negligent act or omission to act by Grantee, its agents, employees, lessees, or
contractors, or subcontractors during the term of this Agreement. The foregoing indemnity from
Grantee shall not extend to liability resulting from the negligence of willful misconduct of Grantor,
or Grantor’s employees, agents, contractors or subcontractors.

       4.     Appurtenant Property. The easement granted and conveyed herein shall be deemed
appurtenant to and shall be used only in connection with the Grantee Property and Grantor
Property.

        5.      Covenants Running With the Land. All of the provisions of this Agreement are
intended to be, and shall be construed as, covenants running with the land and shall be binding
upon, inure to the benefit of, and be enforceable by the parties hereto and their respective lessees,
transferees, successors and assigns for the term of this Agreement. However, neither party shall
have any further rights or obligations under the terms of this Agreement from and after the date
that such party transfers and conveys all of its rights and interests in its property.

3709539_5
        6.     Term. This Agreement shall commence on the Effective Date and shall continue
until the Road Extension is complete and open to the public for vehicular travel, at which time this
Agreement shall automatically terminate.

        7.     No Waiver of Default. No waiver of any default by any party shall be implied from
an omission by another party to take any action in respect to a default if such default continues or
is repeated. One or more waivers of any default in the performance of any term, provision or
covenant of this Agreement shall not be deemed to be a waiver of any subsequent default of same.
The rights and remedies given to any party to this Agreement shall be deemed to be cumulative
and no one of such rights and remedies shall be exclusive of any of the others, or of any other right
or remedy at law or in equity which any such party might otherwise have by virtue of a default
under this Agreement, and the exercise of one such right or remedy by any such party shall not
impair such party’s standing to exercise any other right or remedy.

        8.      No Gift or Dedication. Nothing contained in this Agreement shall be deemed to be
a gift or dedication of any portion of the Grantor Property to the general public or for any public
purposes whatsoever, it being the intention that the easements created herein shall be strictly
limited to and for the purposes expressed in this Agreement.

       9.     Amendments. This Agreement may not be amended, modified, rescinded, limited,
or changed except by written agreement signed by the parties (or their successors and assigns).

       10.    Governing Law. This Agreement shall be construed, interpreted and applied in
accordance with the laws of the State of Michigan.

        11.    Counterparts. This Agreement may be executed in one or more counterparts, and
by separate counterpart signature pages, each of which shall be deemed to be an original. Facsimile
or pdf signatures shall be acceptable.

         12.     Severability. If any term, provision or condition contained in this Agreement shall,
to any extent, be invalid or unenforceable, the remainder of this Agreement (or the application of
such term, provision or condition to persons or circumstances other than those in respect of which
it is invalid or unenforceable) shall not be affected thereby, and each term, provision or condition
of this Agreement shall be valid and enforceable to the fullest extent permitted by law.

                                                                      Brownfield Plan Public Hearing

Submitted By: Pete Wills                                              Department: Economic Dev

Brief Summary: To hold a public hearing and approve the attached resolution which seeks to adopt
an amendment to the City’s Brownfield Plan (Infill Housing Project, 4th Amendment). On October
11th, the BRA approved the Plan Amendment and further recommends that the Muskegon City
Commission approve the Plan Amendment.

Detailed Summary & Background: Staff is seeking to amend the Scattered Site Brownfield Plan to
update the number of eligible parcels within the Plan.
The 4th Amendment removes two mixed-use projects (395 Houston and 301 W. Muskegon -
Catholic Charities), 880 First St-208 W Clay-216 W Clay (880 First St development), Allen Edwin
Homes (former Farmers Market), as well as a modified parcel at the former Froebel School.
Developers for a few of the projects, listed above, are expected to pursue their own Brownfield
Plan Amendment so as to directly benefit from the TIF capture. Removal of these parcels is
necessary in order for them to accomplish that goal.
Ten parcels have been removed from the Plan. The project will now focus on the redevelopment of
495 parcels that are scattered throughout the city. Some of these lots will be split, creating even
more parcels. The plan incorporates two types of redevelopment projects; infill housing on vacant
City lots and the rehab of existing homes (10 detached houses).
•   417 Jackson (former Froebel school) – increased to $1,000,000 in public infrastructure costs if
    water/sewer improvements become necessary.
•   417 Jackson (former Froebel school) – retained $2,000,000 in demo & abatement costs.
•   Staff anticipates potential construction of an additional 28 new infill houses as part of a
    potential redevelopment project of the Froebel site.
•   Removed the properties associated with the former Allen Edwin Homes development at the
    former farmers market. Removal of these parcels did not take out “cost of sale” expenditures
    because Allen Edwin intended to build and own themselves, so those never were included in
    the former “total houses built” estimate. It was included for the infrastructure expenses (alley
    additions). The site is too contaminated and will need its own brownfield if it is to be developed.
The 4th Amendment also includes the following updates:
•   Developer’s Reimbursement Costs: Infill Housing - $11.4M / Demo & Abatement - $2M / Public
    Infrastructure- $1M / Reimbursable Costs of Construction (before 15% contingency): $14.4M
•   Estimated Total Capital Investment: Infill Housing - $107,200,000 / Home Rehab - $500,000 /
    Total estimated capital investment: $107,700,000
•   The Plan anticipates eligible activities, paid through future capture of tax increments, to include
    $11,400,000 cost of sale/seller concessions; $2,000,000 for demolition and abatement;
    $1,000,000 to construct public infrastructure at the former Froebel School; $20,000 for
    brownfield plan preparation and development; a 15% plan contingency fee of $2,163,000; and
    which reflects total eligible activities to be paid under this plan at $16,582,000.
•   The Authority intends to enter into Development & Reimbursement Agreements with future
    property owners/developers of properties included in the Plan to reimburse them for costs of
    eligible activities.
•   The duration of this Plan is not to exceed 30 years and complete recapture of eligible costs
    through tax increment revenue are expected to occur within this period.
•   The plan contemplates continued five-year capture of tax increments for a local Brownfield
    Revolving Loan Fund if there is time left in the 30-year plan after eligible costs are covered.

The project will focus on the redevelopment of 495 parcels that are scattered throughout the city.  Some 
of these lots will be split, creating even more parcels.  The plan incorporates two types of redevelopment 
projects; infill housing on vacant City lots and the rehab of existing homes (10 detached houses). 
 
The residential infill units will consist mostly of detached houses, with some rowhouses, duplexes and 
small multiplexes mixed in as the market dictates.   The infill housing project includes the demolition of 
the former Froebel School (demo and abatement costs) in order to redevelop the property with a variety

1. Introduction  
   The City of Muskegon, Michigan (the “City”), established the Muskegon Brownfield Redevelopment 
   Authority (the “Authority”) on July 4, 1997, pursuant to Michigan Public Act 381 of 1996, as amended 
   (“Act 381”).  The primary purpose of Act 381 is to encourage the redevelopment of eligible property 
   by providing economic incentives through tax increment financing for certain eligible activities.  
   The  main  purpose  of  this  Brownfield  Plan  is  to  promote  the  redevelopment  of  and  investment  in 
   certain “Brownfield” properties within the City.  Inclusion of the subject properties within this Plan 
   will facilitate the development of infill housing at eligible properties.  By facilitating redevelopment of 
   underutilized  properties,  the  Plan  is  intended  to  promote  economic  growth  for  the  benefit  of  the 
   residents of the City and all taxing units located within and benefited by the Authority.   
   This Plan is intended to be a living document, which can be amended as necessary to achieve the 
   purposes of Act 381.  It is specifically anticipated that properties will be continually added to the Plan 
   as new projects are identified.  The Plan contains general provisions applicable to the Plan, as well as 
   property‐specific  information  for  each  project.    The  applicable  Sections  of  Act  381  are  noted 
   throughout the Plan for reference purposes. 

   This  Brownfield  Plan  contains  the  information  required  by  Section  13(1)  of  Act  381,  as  amended.  
   Additional information is available from the Muskegon City Manager or the Planning Director. 

   The Infill Housing Project was originally added to this Plan on April 14, 2019.  It was amended for the 
   first time on July 28, 2020; a second time on December 8, 2020; and a third time on December 13, 
   2021.  This amendment seeks to modify the plan by removing the mixed‐use projects, removing the 
   Allen Edwin development and modifying the Froebel School development.  

    
2. General Provisions 
    
   A. Costs of the Brownfield Plan (Section 13(1)(a)) 
   Any site‐specific costs of implementing this Plan are described in the site‐specific section of the Plan.  
   Site‐specific  sources  of  funding  may  include  tax  increment  financing  revenue  generated  from  new 
   development on eligible brownfield properties, state and federal grant or loan funds, and/or private 
   parties.  Where private parties finance the costs of eligible activities under the Plan, tax increment 
   revenues may be used to reimburse the private parties.  The initial costs related to preparation of the 
   Brownfield Plan were funded by the City’s general fund.  Subsequent amendments to the Plan may 
   be  funded  by  the  person  requesting  inclusion  of  a  project  in  the  Plan,  and  if  eligible,  may  be 
   reimbursed through tax increment financing. 

   The Authority intends to pay for administrative costs and all of the things necessary or convenient to 
   achieve the objectives and purposes of the Authority with fees charged to applicants to be included 
   in the Plan, and any eligible tax increment revenues collected pursuant to the Plan, in accordance with 
   the provisions of Act 381, including, but not limited to: 

   i)      the cost of financial tracking and auditing the funds of the Authority,  
   ii)     costs for amending and/or updating this Plan, and 
   iii)    costs for Plan implementation  
     

    Tax increment revenues that may be generated and captured by this Plan are identified in the site‐
    specific sections of this Plan.   

    B. Method for Financing Costs of Plan (Section 13(1)(d) and (e))  
    The City or Brownfield Authority may incur some debt on a site‐specific basis.  Please refer to the site‐
    specific section of this Plan for details on any debt to be incurred by the City or Authority.  When a 
    property proposed for inclusion in the Plan is in an area where tax increment financing is a viable 
    option,  the  Authority  intends  to  enter  into  Development  Agreements  with  the  property 
    owners/developers  of  properties  included  in  the  Plan  to  reimburse  them  for  the  costs  of  eligible 
    activities  undertaken  pursuant  to  this  Plan.    Financing  arrangements  will  be  specified  in  a 
    Development and Reimbursement Agreement, and also identified in the Site Specific section of the 
    Plan. 

    C. Duration of the Brownfield Plan (Section 13(1)(f)) 

    The duration of this Plan is not to exceed 30 years.  It is the goal of the city to build as many homes as 
    possible over that time frame, however, it is unlikely that all 495 parcels will be developed.  Since the 
    “cost of sale” will vary for each home, as will construction costs, it is impossible to know exactly how 
    long it will take to completely recapture eligible costs through tax increment revenues, although it is 
    anticipated that it will be well within the 30 year time frame.  In addition, once all activity costs are 
    reimbursed, funds may be captured for the local site remediation revolving fund, if available.  The 
    duration of capture for the Project already began in 2020 and will continue until such time that all the 
    eligible activities undertaken in this Plan are reimbursed, but in  no event will the Plan  exceed  the 
    maximum  duration  provided  for  in  (MCLA  125.2663(1)(22)).    The  total  costs  of  eligible  activities 
    include the cost of principal and interest on any note or obligation issued by the Authority to pay for 
    the costs of eligible activities, the cost of principal and interest otherwise incurred to pay for eligible 
    activities, the reasonable costs of a work plan or remedial action plan and the costs of preparation of 
    Brownfield Plans and amendments. 

    D. Displacement/Relocation of Individuals on Eligible Properties (Section 13(1)(i),(j)(k)(l) 
     
    Eligible  properties  identified  in  this  Plan  will  not  require  the  displacement/relocation  of  existing 
    residences, therefore the provisions of Section 13(1)(i‐l) are not applicable at this time.   
 

    E.  Local Site Remediation Revolving Fund (Section 8; Section 13(1)(m))  
 
    Whenever this Plan includes a property for which taxes will be captured through the tax increment 
    financing authority provided by Act 381, it is the Authority's intent to establish and fund a Local Site 
    Remediation Revolving Fund ("Fund").  The Fund will consist of tax increment revenues that exceed 
    the costs of eligible activities incurred on an eligible property, as specified in Section 13(5) of Act 381.  
    Section 13(5) authorizes the capture of tax increment revenue from an eligible property for up to 5 
    years after the time that capture is required for the purposes of paying the costs of eligible activities 
    identified  in  the  Plan.    It  is  the  intention  of  the  Authority  to  continue  to  capture  tax  increment 
    revenues for 5 years after eligible activities are funded from those properties identified for tax capture 
      in  the  Plan,  provided  that  the  time  frame  allowed  by  Act  381  for  tax  capture  is  sufficient  to 
      accommodate capture to capitalize a Fund.  The amount of school operating taxes captured for the 
      Revolving  Fund  will  be  limited  to  the  amount  of  school  operating  taxes  captured  for  eligible 
      environmental  response  activities  under  this  Plan.    It  may  also  include  funds  appropriated  or 
      otherwise made available from public or private sources.  
 
      The Revolving Fund may be used to reimburse the Authority, the City, and private parties for the costs 
      of eligible activities at eligible properties and other costs as permitted by Act 381.  It may also be used 
      for  eligible  activities  on  an  eligible  property  for  which  there  is  no  ability  to  capture  tax  increment 
      revenues.  The establishment of this Revolving Fund will provide additional flexibility to the Authority 
      in facilitating redevelopment of brownfield properties by providing another source of financing for 
      necessary eligible activities.
