Ten Towns Committee
Model Stormwater Management Ordinance
 
This model ordinance has been prepared by the 10 Towns Great Swamp Watershed Committee as a prototype for adoption by its municipal government members.   See Note .

1.   STATUTORY AUTHORITY

The Municipal Land Use Law, N.J.S.A. 40:44D-1 et seq. and the Soil Erosion and Sediment Control Act, N.J. S.A. 4:24-39 et seq., provide the statutory authority for this ordinance.

2.   FINDINGS OF FACT

It is hereby determined that:

  • Waterbodies, roadways, structures and other property within the municipality are at times subjected to flooding;
  • Flooding is a danger to the lives and property of the public and is also a danger to the natural resources of the municipality and the region;
  • Land development projects and activities alter the hydrologic response of watersheds resulting in increased stormwater runoff rates and volumes, increased flooding, increased stream channel erosion and increased sediment and pollutant transport and deposition;
  • Land development projects and activities result in the construction of impervious surfaces, such as roads and parking lots, from which stormwater runoff flushes particulate and dissolved contaminants into streams and wetlands.
  • Stormwater runoff, soil erosion, stream channel erosion and nonpoint source pollution resulting from land development activities within the municipality have resulted in a deterioration of the water resources of the municipality.
  • Soil erosion, stream channel erosion and nonpoint source pollution can be controlled and minimized by the regulation of stormwater runoff from land development projects and activities.
  • The State of New Jersey's Surface Water Quality Standards (N.J.A.C. 7:9B-1.1 et seq.) establish surface water quality standards and antidegradation policies applicable to all surface waters of the state and these standards and antidegradation policies provide reasonable guidance to New Jersey municipalities for the regulation of stormwater runoff for purposes of protecting surface water resources from degradation.
  • Impervious surfaces and regraded earth surfaces associated with land development reduce the infiltration of rainfall and the recharge of groundwater resources.
  • It is therefore determined that it is in the public interest to regulate stormwater runoff from land development projects and other construction activities within (insert municipal name) as provided in this ordinance in order to control and minimize increases in stormwater runoff rates and volumes, to control and minimize soil erosion, stream channel erosion, and nonpoint source pollution associated with stormwater runoff and to provide for the recharge of groundwater resources.

3.   PURPOSE

  • It is the purpose of this ordinance to establish standards and regulations for the management and discharge of stormwater runoff from land development projects and other construction activities;
  • To reduce artificially induced flood damage to public health, life, and property;
  • To minimize increased stormwater runoff rates and volumes;
  • To minimize the deterioration of existing water courses, culverts, bridges, dams and other structures that would result from increased rates of stormwater runoff;
  • To induce water recharge into the ground wherever suitable infiltration, soil permeability, and favorable geological conditions exist;
  • To prevent an increase in nonpoint source pollution;
  • To maintain the integrity and stability of stream channels for their biological functions, as well as for drainage, the conveyance of floodwater, and other purposes;
  • To control and minimize soil erosion and the transport of sediment;
  • To reduce stormwater runoff rates and volumes, and nonpoint source pollution;
  • To minimize public safety hazards at any stormwater detention facility constructed pursuant to subdivision or site plan approval;
  • To maintain high water quality in all streams and other surface water bodies;
  • To protect all surface water resources from degradation; and
  • To protect groundwater resources from degradation.

4.   APPLICABILITY

This ordinance shall be applicable to any major subdivision or site plan application, as defined in the Municipal Land Use Law, located within the municipality, which involves disturbances of 1,000 square feet or more. Provisions of this ordinance pertaining to runoff from roof areas and requirements for drywells shall also apply to all applications for building permits except as otherwise provided for herein (Policy decision). The ordinance shall be applied to achieve its purposes to the extent reasonable and practical with respect to modifications of previously developed sites consistent with the nature and extent of such modifications.

5.   DEFINITIONS

Unless specifically defined below, or in the Municipal Land Use Law (N.J.S.A. 40:55D-1 et seq.), or in the Soil Erosion and Sediment Control Act (N.J.S.A. 4:24-39 et seq.), or in New Jersey's Surface Water Quality Standards (N.J.A.C. 7:9B-1.1 et seq.), words or phrases used in this ordinance shall be interpreted so as to give them the meaning they have in common usage.

    (Municipalities should include the following definitions in their adopted ordinance unless the definition is already provided for in the adopted zoning ordinance)
     
  • Agricultural development - land uses normally associated with the production of food, fiber, and/or livestock for sale. For purposes of this ordinance, such uses shall not include the development of land for the processing or sale of food and the manufacture of agriculturally related products.
  • Constructed wetland - a man-made freshwater wetland, designed and constructed for a specific purpose.
  • Detention basin - an impoundment area created by constructing an embankment, excavating a pit, or both, for the purpose of temporarily storing stormwater.
  • Detention facility - a detention basin or alternative structure designed to store stormwater runoff.
  • Floodplain - the area inundated by NJDEP's regulatory flood including the water course that creates it. NJDEP's regulatory flood means NJDEP's adopted Flood Hazard Area Design Flood along streams for which NJDEP has an adopted flood hazard area and floodway study, and the 100-year flood along non-delineated streams for which NJDEP has not delineated a flood hazard area.
  • Floodway - the channel of a natural stream and portions of the flood hazard areas adjoining the channel which are reasonably required to carry and discharge the regulatory flood. For this ordinance, the term floodway refers to both the delineated floodway along streams which have state adopted flood hazard area and floodway studies, and the area between NJDEP approved encroachment lines located on both sides of non-delineated streams for which no state adopted flood hazard area and floodway study exists.
  • Freshwater wetlands - an area that is inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances does support, a prevalence of vegetation typically adapted for life in saturated soil conditions, commonly known as hydrophytic vegetation; provided, however, that in designating a wetland, the three parameter approach (that is, hydrology, soils and vegetation) enumerated in the "Federal Manual for Identifying and Delineating Jurisdictional Wetlands," and any subsequent amendments thereto shall be used.
  • Infiltration facility - structure or device designed to infiltrate retained water to the subsurface and which is not an injection well. These facilities may be above grade or below grade.
  • NJDEP - the New Jersey Department of Environmental Protection.
  • Nonpoint source pollution - pollution from any source other than from any discernible, confined, and discrete conveyances, and shall include, but not be limited to, pollutants from agricultural, silvicultural, mining, construction, subsurface disposal and urban runoff sources.
  • Recharge - the replenishment of underground water reserves.
  • Regulatory flood - the 100-Year flood along non-delineated watercourses or the Flood Hazard Area design flood along delineated watercourses.
  • Retention Basin - an impoundment area with a permanent pool made by constructing an embankment, or excavating a pit, or both, for the purpose of temporarily storing storm water. A retention basin is also called a "wet basin" or "wet detention basin".
  • Somerset County Storm Water Detention Basin Handbook - the Handbook for Storm Water Detention Basins (with supplement) dated December 1991, published by the County of Somerset, New Jersey, and any subsequent revisions or amendments thereto.
  • Stormwater runoff - flow on the surface of the ground, resulting from precipitation.
  • S.C.S. - the Soil Conservation Service (now the Natural Resources Conservation Service) of the U.S. Department of Agriculture.
  • Treatment train - a sequence of structures or devices through which runoff passes before exiting the project site. The combined characteristics of the individual structures or devices shall satisfy the performance requirements associated with the no net increase provisions of this ordinance.
  • Water Quality Storm - a one-year frequency, 24-hour storm, (2.7 inches of rainfall), using the Type III rainfall distribution recommended for New Jersey by the U.S. Soil Conservation Service or a storm of 1.25 inches of rainfall falling uniformly in two hours.

6.   TECHNICAL STANDARDS

  1. No Net Increase Goals
    1. No net increase in nonpoint source pollution - Stormwater control systems shall be designed to prevent the degradation of water quality in receiving watercourses from nonpoint source pollution associated with stormwater runoff. NJDEP's Surface Water Quality Standards, NJAC 7:9B, shall be used for this determination.
    2. No net increase in sediment loadings - Stormwater control systems shall be designed to reduce to the maximum extent possible, the total suspended solids (TSS) from stormwater runoff for storm events with magnitudes as high as the Water Quality Storm and to retain, as closely as possible, the pre-development hydrologic response of the site and the watershed.
    3. No net increase in stormwater runoff rates and stream channel erosion - Stormwater control systems shall be designed so that, to the maximum extent possible, the post­development stormwater runoff rates from the site and at any point in the watershed between the site are no greater than pre-development rates, in order to retain as closely as possible the pre-development hydrologic response of the site and the watershed.
    4. No net increase in stormwater runoff volumes - Wherever suitable infiltration, soil permeability, and favorable geological conditions exist, stormwater control systems shall be designed so that all stormwater runoff from impervious surfaces is infiltrated into the soil for the 1.25 inch, 24-hour storm, using the Type III rainfall distribution recommended for New Jersey by the U.S. Soil Conservation Service or the Somerset County 24-Hour Design Storm Distribution as shown in the Somerset County Storm Water Detention Basin Handbook. The first 1.25 inches of stormwater runoff from all larger storms shall also be infiltrated into the ground so that a minimum of 1.25 inches of stormwater runoff is infiltrated for all storms of 1.25 inches or greater.
  2. Procedures for Measuring Compliance with the No Net Increase Goals of the Ordinance
    1. Hydrologic/hydraulic analyses shall be prepared and submitted demonstrating that the post-development stormwater runoff rates do not exceed the standards set forth in this ordinance for the water quality storm and the 2, 10, 25, 50 and 100-year storms.
      1. The hydrologic and hydraulic analyses shall generally conform with methods developed by the Natural Resources Conservation Service and published in National Engineering Handbook, Section 4 - Hydrology, Technical Release No. 55 and Technical Release No. 20.
      2. Standards and procedures for developing hydrographs and calculating peak rates of runoff shall be as shown in the Somerset County Storm Water Detention Basin Handbook.
      3. Rainfall - Frequency relationships shall be as shown in Technical Paper No. 40, Rainfall Frequency Atlas of the United States published by the U.S. Weather Bureau.
    2. For infiltration facilities proposed to meet the no net increase goals of this ordinance, the results of a subsurface investigation and soil tests demonstrating the suitability of the area's soils and groundwater table for infiltration and treatment of runoff shall be provided.
    3. A nonpoint source pollutant loading analysis shall be prepared and submitted, demonstrating that the nonpoint source pollutant and sediment loadings resulting from the proposed land development or construction project do not exceed the standards set forth in this ordinance.
    4. In preparing the required analysis it shall be acceptable to utilize the average removal efficiency statistics provided in the Stormwater and Nonpoint Source Pollution Control Best Management Practices Manual, dated December 1994, and any subsequent revisions thereto, prepared by the N.J.D.E.P. and the New Jersey Department of Agriculture.
       
  3. Waivers From Strict Compliance

    If the natural or existing physical characteristics of the project site preclude achievement of any of the above no net increase goals, the municipality may grant a waiver from strict compliance with the specific no net increase provisions the achievement of which are precluded, provided that the applicant demonstrates to the satisfaction of the municipal engineer that the adjacent waterways will not be impacted by the:

    1. Deterioration or damage of existing culverts, bridges, dams, and other structures;
    2. Deterioration of their biological functions, drainage, flood water conveyance, and other purposes;
    3. Streambank or streambed erosion or siltation;
    4. Increased flooding endangering public health, life and property.

    Where partial compliance with a specific no net increase provision is possible, the municipal engineer will direct the applicant to satisfy a reduced performance criterion. However, those no net provisions that are not precluded by the site's physical characteristics shall be met.

    If one or more of the "no net increase" goals of this ordinance cannot be met on-site, the applicant shall provide off-site mitigation subject to the approval of the Planning Board/Zoning Board prior to project commencement. Options for mitigation are as follows:
     

      The acquisition of privately owned lands, preferably adjacent to state open waters, located in the municipality can be dedicated for preservation or reforestation, in equivalent size to off-set the increase in volume of the Water Quality Storm from the proposed development site.

     
  4. Mitigation can be performed on previously developed properties, public or private, within the municipality and preferably within the same drainage basin that currently lack stormwater management facilities designed and constructed in accordance with the purposes and standards of this ordinance. If infiltration is not feasible on the subject site, a construction cost estimate of a suitable infiltration system sized for the proposed development based on the assumption that average permeability had existed on the subject property shall be prepared and submitted by the applicant’s professional engineer. Upon certification by the municipal engineer that the proposed design and estimate are reasonable, the amount so determined will be the amount required to provide other mitigation measures on previously developed or undeveloped properties.
  5. Stormwater related studies or regional stormwater management plans can be funded or specific projects recommended by the Ten Towns Great Swamp Watershed Management Committee can be implemented to the extent of the funds estimated under the procedure described in Paragraph 2 above. This requirement shall be applied equally to all applications for development and redevelopment within the municipality. Increased stormwater runoff shall be calculated by the applicant’s engineer and approved by the municipal engineer utilizing accepted engineering practices.
  6. Design Standards for Detention and Retention Basins and Other Stormwater Management Measures
     
      Design standards for detention and retention basins and other stormwater management measures are contained in the Stormwater Management Manual, dated (insert date) and any subsequent updates or revisions thereto, prepared by the Ten Towns Great Swamp Watershed Management Committee. These design standards shall be used for the design of detention and retention basins and all other stormwater management measures.

     
  7. Water Quality Control and Infiltration Measures
    1. In most instances, the water quality control and infiltration performance requirements of this ordinance will be satisfied by multiple structures or devices (see Sections 6F and 6G of this ordinance). Furthermore, most structures or devices will achieve both a water quality control and infiltration benefit. Compliance with the no net increase provisions of the ordinance will be based on a project-wide summation of runoff characteristics. The applicant shall show how the collection of structures or devices incorporated in the stormwater management plan will jointly satisfy the performance requirements of this ordinance.
    2. In order to meet the no net increase provisions of this ordinance with regard to stormwater runoff volumes, sediment loadings, and other nonpoint source pollutant loadings, stormwater management facilities shall provide for the control of stormwater runoff in accordance with the following basic principles:
      1. Infiltration should be implemented which will retain and infiltrate all runoff generated for storms up to the 1.25 inch, 24-hour storm, using the Type III rainfall distribution recommended for New Jersey by the U.S. Soil Conservation Service or the Somerset County 24-Hour Design Storm Distribution.
      2. Runoff shall be managed at the source whenever possible.
      3. Water quality and infiltration device treatment trains shall be designed that utilize the natural qualities of the landscape.
      4. Detention/retention basins are generally not suitable as infiltration facilities.
    3. Utilizing the above design principles, a stormwater management plan shall be designed for the project area, utilizing the stormwater control "Best Management Practices" (BMPs) presented in Stormwater and Nonpoint Source Pollution Control Best Management Practices Manual, dated December 1994, prepared by the New Jersey Department of Environmental Protection and the New Jersey Department of Agriculture, as from time to time revised or amended.
    4. In estimating the removal efficiencies of the water quality control measures proposed, it shall be acceptable to utilize the average removal efficiency statistics provided in the Stormwater and Nonpoint Source Pollution Control Best Management Practices Manual, dated December 1994, prepared by the New Jersey Department of Environmental Protection and the New Jersey Department of Agriculture as from time to time revised or amended.
  8. Dry Well Requirements for Roof Runoff and Runoff from Paved Recreation Courts

    Wherever suitable infiltration, soil permeability, and favorable geological conditions exist, runoff from roof areas and paved recreation courts, such as tennis and basketball courts, and impervious patios shall be transported to dry wells for recharge of groundwater resources. Standards for the design of dry wells are contained in the Stormwater Management Manual, dated (insert date) and subsequent updates and revisions thereto, prepared by The Ten Towns Great Swamp Watershed Management Committee. These design standards shall be used for the design of dry wells.
     

  9. Planning and Design Standards for Maintenance and Repair

    A goal for the planning and design of a stormwater management facility is for its operation with the least practical amount of maintenance. To accomplish this, the facility shall be developed to eliminate avoidable maintenance tasks, minimize the long term amount of regular maintenance, facilitate the performance of required maintenance tasks, and reduce the potential for extensive, difficult, and costly remedial or emergency maintenance efforts. Standards for maintenance and repair are contained in the Stormwater Management Manual, dated (insert date) and subsequent updates and revisions, prepared by The Ten Towns Great Swamp Watershed Management Committee. These standards shall be followed for the maintenance and repair of all stormwater management measures.
     

  10. Safety Measures

    Safety measures are to be incorporated in the design of all stormwater and infiltration control projects. These may include but not be limited to fencing, warning signs, staff gauges indicating depth at lowest point, and outlet structures designed to limit access. Standard safety measures for stormwater management facilities are contained in the Stormwater Management Manual, dated (insert date) and subsequent updates and revisions prepared by the Ten Towns Great Swamp Watershed Management Committee.
     

7.   REQUIREMENTS FOR A STORMWATER MANAGEMENT PLAN
