Article I - General

Sec. 1.01 Statutory Authority and Title

This ordinance is adopted in accordance with the Charter Township Act, as amended, being MCL 42.1, et seq.; the Township and Village Public Improvement Act, as amended, being MCL 41.721, et seq.; the Drain Code of 1956, as amended, being MCL 280.1, et seq.; the Land Division Act, as amended, being MCL 560.1, et seq.; the Revenue Bond Act, as amended, being MCL 141.101, et seq.; and the Natural Resources and Environmental Protection Act, as amended, being MCL 324.101, et seq.; Section 401(p) of the Federal Water Pollution Control Act (also known as the Clean Water Act), as amended, being 33 USC 1342(p) and 40 CFR Parts 9, 122, 123 and 124; and other applicable state and federal laws.

This ordinance shall be known and may be cited as the Cascade Charter Township Storm Water Ordinance.

Sec. 1.02 Findings

The Cascade Charter Township finds that:

(1) Water bodies, roadways, structures, and other property within, and downstream of the Township 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 Township and the region;

(3) Land development alters the hydrologic response of watersheds, resulting in increased storm water runoff rates and volumes, increased flooding, increased stream channel erosion, and increased sediment transport and deposition;

(4) Storm water runoff produced by land development contributes to increased quantities of water-borne pollutants;

(5) Increases of storm water runoff, soil erosion, and non-point source pollution have occurred as a result of land development, and cause deterioration of the water resources of the Township and downstream municipalities;

(6) Storm water runoff, soil erosion, and non-point source pollution, due to land development within the Township, have resulted in a deterioration of the water resources of the Township and downstream municipalities;

(7) Increased storm water runoff rates and volumes, and the sediments and pollutants associated with storm water runoff from future development projects within the Township will, absent reasonable regulation and control, adversely affect the Township's water bodies and water resources, and those of downstream municipalities;

(8) Storm water runoff, soil erosion, and non-point source pollution can be controlled and minimized by the regulation of storm water runoff from development;

(9) Adopting the standards, criteria and procedures contained in this ordinance and implementing the same will address many of the deleterious effects of storm water runoff;

(10) Adopting these standards is necessary for the preservation of the public health, safety and welfare.

Sec. 1.03 Purpose

It is the purpose of this ordinance to establish minimum storm water management requirements and controls to accomplish, among others, the following objectives:

(1) To reduce artificially induced flood damage;

(2) To minimize increased storm water 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 non-point 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;

(9) To preserve and protect water supply facilities and water resources by means of controlling increased flood discharges, stream erosion, and runoff pollution; and,

(10) To reduce storm water runoff rates and volumes, soil erosion, and non-point source pollution, wherever practicable, from lands that were developed without storm water management controls meeting the purposes and standards of this ordinance.

(11) To reduce the adverse impact of changing land use on water bodies and, to that end, this ordinance establishes minimum standards to protect water bodies from degradation resulting from changing land use where there are insufficient storm water management controls.

Article VII – Storm Water Easements and Maintenance Agreements

Sec. 7.01 Applicability of Requirements

The requirements of this Article concerning storm water easements and maintenance agreements shall apply to all persons required to submit a drainage plan to the Township for review and approval.

Sec. 7.02 Storm Water Management Easements

The developer shall provide all storm water management easements necessary to implement the approved drainage plan and to otherwise comply with this ordinance in form and substance required by the Township and shall record such easements as directed by the Township. The easements shall assure access for proper inspection and maintenance of storm water runoff facilities and shall provide adequate emergency overland flow-ways.

Sec. 7.03 Maintenance Agreements

The developer shall provide all storm water maintenance agreements necessary to implement the approved drainage plan and to otherwise comply with this ordinance in form and substance as required by the Township, and shall record such agreements as directed by the Township. The maintenance agreements shall, among other matters, assure access for proper inspection and maintenance of storm water runoff facilities and adequate emergency overland flow-ways.

Sec. 7.04 Establishment of County Drains

Before final approval, all storm water management facilities for platted subdivisions shall be established as county drains, as authorized in Section 433, Chapter 18 of the Michigan Drain Code (P.A. 40 of 1956, as amended) for long-term maintenance.

Article VIII – Performance and Design Standards

Sec. 8.01 Performance Standards

In order to achieve the goals and purposes of this ordinance, the following three storm water management zones (Zones A, B and C) are hereby established. The Zones are shown on the map attached as Appendix A and made a part of this ordinance.

(1) Zone A represents areas that require the most protective storm water management regulations. The goal of this zone is to preserve the natural condition of water bodies included in it, in whole or in part. Zone A has, in general, little impervious surface area and few storm water facilities. In this zone, when site conditions permit, infiltration of storm water runoff shall be required, rather than the directed flow of storm water runoff into water bodies. This storm water management practice provides greater protection for surface water quality, and assists in augmenting stream base flow, reduction of flash storm flows and prevention of stream bank erosion. Section 8.02 specifies design criteria for Zone A, in order that the volume and rate of storm water runoff are controlled at predevelopment levels.

(2) Zone B represents developed areas that have significant impervious surfaces and storm water runoff facilities in place. The goal of Zone B is the control of storm water runoff in order to prevent further destabilizing of streams and other water bodies. In this zone, the use of detention ponds, the maintenance and enhancement of buffer strips and other measures to reduce directly-connected impervious areas are specified in Section 8.02 for the achieving of the storm water management standards applicable to Zone B. The management practices for this zone are intended to maintain existing water quality and to alleviate adverse downstream impact on water bodies.

(3) Zone C consists of highly urbanized areas, or areas where there has been significant modification of drainageways. Areas with adequate conveyance capacity for a 100-year storm to a river or lake may also be located in Zone C. Among the measures required in Zone C, as stated in Section 8.02, are the use of sediment basins, the maintenance and enhancement of buffer strips along water bodies and the reduction of impervious surface areas that are directly connected to water bodies. An important element of storm water management practice in Zone C is the control and prevention of sedimentation, in order to reduce pollution of water bodies.

Sec. 8.02 Design Standards As amended by Ord no 2 of 2008; 5/14/2008

1) Storm Zone A Flood Control Requirements:
a. Utilize retention ponds (above or below grade) and infiltration to the greatest extent possible as allowed by the local soil conditions
b. Design shall be in accordance with the Kent County Drain Commissioner's Development Drainage Rules for Retention Ponds with the following modifications:
i. A minimum of two soil borings extending a minimum of 10 feet below each proposed basin bottom with sieve/permeability analysis of the soil in the 10 feet immediately below each proposed basin bottom.
ii. Retention basins shall be designed to store runoff from a single 100 year storm event
c. If soil condition do not permit infiltration, storm water facilities will satisfy one of the following:
i. Provide a permanent on-site storm water system with a restricted outlet sufficient to provide on-site detention of storm water runoff in a twenty-five (25) year storm event, and a direct connection (overland or underground) for all storm water runoff that will be discharged from and through the development site in a one hundred (100) year storm event; or
ii. Provide a permanent on-site storm water system with a restricted outlet designed to provide on-site detention or on-site retention of storm water runoff in a one hundred (100) year storm event.

2) Storm Zone B Flood Control Requirements must satisfy one of the following:
a) Provide a permanent on-site storm water system with a restricted outlet sufficient to provide on-site detention or on-site retention of storm water runoff in a twenty-five (25) year storm event, and a direct connection (overland or underground) for all storm water runoff that will be discharged from and through the development site in a one hundred (100) year storm event; or

b) Provide a permanent on-site storm water system with a restricted outlet designed to provide on-site detention or on-site retention of storm water runoff in a one hundred (100) year storm event.

3) The following shall be in accordance with the Kent County Drain Commissioner's Development Drainage Rules:
a. Design storm duration and distribution
b. Required Calculation Methods
c. Emergency Spillway Design

4) If proposed site grading changes the surface area contributing to specific discharge points on the site, storm water control release rates shall be based on pre-development contributing areas.

5) All storm water control systems shall be designed to convey storm water from off-site around, not through, the proposed on-site storm water system and shall be provide pass-through capacity of the 25 year storm event for all off-site drainage, provided a 100 year floodway is available.

6) Storm systems designed to work in-line with drainage courses conveying off-site drainage shall be subject to special review and may be subject to more stringent requirements.

7) On-site storm water conveyance systems shall be designed to convey storm water runoff from a ten (10) year storm event using Manning's Equation for full flow capacity calculations

8) Water quality controls for Storm Zone C and equivalent treatment for Storm Zones A and B shall be designed to meet a removal efficiency of 75% for a very fine sand (settling velocity of 0.03-feet per second)

a. Removal efficiency of sediment basins shall be determined with the following formula: E = 1-(1+ AV/NQ)-N

E = 75% removal efficiency (decimal form)
A = Basin surface ares (sf)
V = Particle velocity (0.03 ft/sec)
N = Number of sediment cells
Q = Inflow (cfs)

9) All underground detention/retention basins shall have water quality controls to prevent sediment from entering the detention/retention system. Access for maintenance and sediment removal shall be provided.

10) The design standards for storm water runoff facilities for Zones A, B and C, as described in Section 8.01, also include the following:

  Zone A Zone B Zone C
Storm Water Management Standards Use infiltration basins,
infiltration trenches,
extended detention basins, and/or constructed wetlands. Maintain and enhance buffer strips.
Use detention ponds;
maintain and enhance buffer strips, and reduce directly connected impervious area.

Water Quality Control Detain the first 0.5" of runoff from the contributing watershed, with infiltration where conditions permit, with 24 hours of detention, or provide equivalent treatment Detain the first 0.5" of runoff from the contributing watershed for 24 hours or provide equivalent treatment. Provide sedimentation control within the drainage system.
Bank Erosion Control Rate of release shall be limited to 0.05 cfs/acre for a 2-year storm event. Storm water runoff shall not exceed the capacity of the downstream conveyance system. Storm water runoff shall not exceed the capacity of the downstream conveyance system.
Flood Control Detention with infiltration when conditions permit.
Release rate of 0.13 cfs/acre per KCDC rules.
Release rate of 0.13 cfs/acre per KCDC rules. Direct conveyance of storm water runoff within the capacity of downstream system.

ORDINANCE DECLARED ADOPTED.

By Ron Goodyke Township Clerk

CERTIFICATION
I hereby certify the above to a true copy of an Ordinance adopted by the Cascade Charter Township Board at a regular meeting held at the Cascade Library - Wisner Center on the 14th day of May, 2008, at 7:00 p.m., pursuant to the required statutory procedures.
By Ron Goodyke Township Clerk

Resolution 24 of 2002

Whereas, on May 22, 2002, the Cascade Charter Township Board adopted Ordinance No.7 of 2002, the Storm Water Ordinance;

Whereas, Section 8.03 of said ordinance provides that Cascade Charter Township may adopt by resolution additional design and performance standards for water runoff facilities, consistent with the terms of the ordinance, in order to further implement its goals and purposes;

Whereas, the Cascade Charter Township Board now desires to adopt such additional design and performance standards for storm water runoff facilities and other standards pertaining to storm water management.

It Is Therefore Resolved As Follows:

Section 1. Storm Water Management Zones. 

The performance standards stated in Section 8.01 of said ordinance are hereby supplemented as follows:

a) In any single development site, up to three different detention volumes may be calculated to determine the staged outlet elevations: (1) water quality control, (2) bank erosion control, and (3) flood control. The volumes are not intended to be additive; the flood control volume shall include the water quality and bank erosion control volumes.

b) The default flood control volume shall be based on detaining the 25-year storm frequency so long as the downstream storm water conveyance system has adequate capacity and includes an acceptable emergency overland floodway. If the design engineer determines the downstream conveyance system is not adequate or an acceptable emergency overland floodway does not exist, then the flood control volume shall be based on detaining the 100-year storm.

Section 2. Flood Plain Protection. 

Section 8.01of said ordinance is supplemented as follows:

a) Natural floodway filling or alteration shall not be allowed without review and approval by Cascade Charter Township and compliance with the Floodplain Regulatory Authority found in Part 31, Water Resource Protection, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA) on watercourses with contributing drainage are of 2 square miles or greater. If floodway has not been mapped, the applicant's consultant shall provide the floodway delineation to Cascade Charter Township for approval.

b) Natural floodway fringe filling or alteration shall not be allowed without review and approval by Cascade Charter Township and compliance with the Floodplain Regulatory Authority found in Part 31, Water Resource Protection, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA) on watercourses with contributing drainage are of 2 square miles or greater. If floodway has not been mapped, the applicant's consultant shall provide the floodway delineation to Cascade Charter Township for approval.

c) To provide for stream bank stability a buffer zone is to be established and called out on a recorded plat, an approved block grading plan, a site plan or an improvement plan. This zone shall consist of existing natural tree and vegetation slope protection within a minimum of 24 feet from the ordinary high-water mark.

d) Replacement of lost floodplain shall meet the following criteria.
a. Replacement of the loss of floodplain storage volume at a 1 to 1 ratio unless watershed conditions warrant a higher ratio. This applies to floodplain associated with rainfall events up to a 100-year frequency. The grading plan shall provide for an equivalent volume of storage for floodplains associated with more frequent events such as 10 and 25-year frequencies.
b. Storm water detention does not apply toward the replacement volume.
c. Floodplain storage volume shall be computed above the seasonal high ground water level only.
d. The inflow and outflow rates to the area shall be consistent with predevelopment rates.
e. Up to 50% of the floodplain mitigation storage volume may be used for snow storage.
f. The proximity of the floodplain mitigation area shall provide for an equivalent hydrologic impact to the receiving stream and adjacent parcels.
