Increases of stormwater runoff, soil erosion and nonpoint-source pollutants have occurred in the past as a result of land development, and contribute to the degradation of the water resources of the Township of Washington.
The Township of Washington's natural resources are to be protected in accordance with New Jersey's Stormwater Management Rules at N.J.A.C. 7:8-1.1 et seq., and New Jersey's surface water quality antidegradation policies contained in the New Jersey Surface Water Quality Standards at N.J.A.C. 7:9B-1.1 et seq. Permitted uses shall maintain the ecological character and quality of the Township of Washington, including good water quality and natural rates and volumes of flow.
Increased stormwater rates and volumes and the sediments and pollutants associated with stormwater runoff from future development projects within the Township of Washington have the potential to adversely affect the Township of Washington's streams and water resources and the streams and water resources of downstream municipalities.
It is in the public interest to regulate the discharge of stormwater runoff from major development projects, as defined in § 214-7 of this chapter, conducted within the Township of Washington, as provided in this chapter, in order to control and minimize increases in stormwater runoff rates and volumes, to maintain groundwater recharge, and to control and minimize soil erosion, stream channel erosion and nonpoint-source pollution associated with stormwater runoff.
Therefore, it is the purpose of this chapter to establish minimum stormwater management requirements and controls for major development consistent with the statewide stormwater requirements at N.J.A.C. 7:8 and the provisions of the adopted Master Plan and land use ordinances of the Township of Washington.
Through this chapter, the Township of Washington has established the following goals for stormwater control:
To restore, protect, maintain and enhance the quality of the streams and water resources and the ecological character and quality of the Township of Washington;
To minimize pollutants in stormwater runoff from new and existing development in order to restore, protect, enhance and maintain the chemical, physical and biological integrity of the surface waters and groundwaters of the Township of Washington, to protect public health and to enhance the domestic, municipal, recreational, industrial and other uses of water; and
In order to achieve the goals for stormwater control set forth in this chapter, the Township of Washington has identified the following management techniques:
This chapter shall also be applicable to all major developments undertaken by the Township of Washington.
Procedures. In addition to other development review procedures set forth in the Code of the Township of Washington, major developments located within the Township of Washington shall comply with the stormwater management requirements and specifications set forth in this chapter. New agricultural development that meets the definition of major development in § 214-7 of this chapter shall be submitted to the appropriate Soil Conservation District for review and approval in accordance with the requirements of N.J.A.C. 5.4(b) 7:8.
In the event that a regional stormwater management plan(s) is prepared and formally adopted pursuant to N.J.A.C. 7:8-1.1 et seq., for any drainage area(s) or watershed(s) of which the Township of Washington is a part, the stormwater provisions of such a plan(s) shall be adopted by the Township of Washington within one year of the adoption of a regional stormwater management plan (RSWMP) as an amendment to an areawide water quality management plan.

Based upon the Municipal Engineer's review of the as-built plans, all corrections or remedial actions deemed by the Municipal Engineer to be necessary due to the failure to comply with the standards established by this chapter and/or any reasons of public health or safety, shall be completed by the applicant. In lieu of review by the Municipal Engineer, the Township of Washington reserves the right to engage a professional engineer to review the as-built plans. The applicant shall pay all costs associated with such review.
The predevelopment field test permeability rate shall be determined according to the methodologies provided in § 214-11C(3) of this chapter;
After all construction activities have been completed on the site and the finished grade has been established in the infiltration BMP, postdevelopment field permeability tests shall also be conducted according to the methodologies provided in § 214-11C(3) of this chapter;
If the results of the postdevelopment field permeability tests fail to achieve the minimum required design permeability rates in Subsection B(4) above utilizing a factor of safety of two, the stormwater infiltration BMP shall be renovated and re-tested until such minimum required design permeability rates are achieved; and
The design engineer shall conduct a mounding analysis, as defined in § 214-7, of all stormwater infiltration BMPs. The mounding analysis shall be conducted in accordance with the requirements in § 214-11C(3)(l). Where the mounding analysis identifies adverse impacts, the stormwater infiltration basin shall be redesigned or relocated, as appropriate.
All other infiltration BMP construction in this section shall be followed when the drainage area is completely stabilized, all accumulated sediment shall be removed from the infiltration BMP, which shall then be excavated to its final design elevation in accordance with the construction requirements of this section and the performance standards in § 214-6.
Applicability. Projects subject to review pursuant to § 214-1C of this chapter shall comply with the requirements of § 214-6B and C below.
The design engineer shall prepare an inspection, maintenance and repair plan for the stormwater management measures, including both structural and nonstructural measures incorporated into the design of a major development. This plan shall be submitted as part of the checklist requirements established in § 214-2C. Inspection and maintenance guidelines for stormwater management measures are available in the New Jersey BMP Manual.
The person responsible for inspection, maintenance and repair identified under Subsection B(2) above shall maintain a detailed log of all preventative and corrective maintenance performed for the site's stormwater management measures, including a record of all inspections and copies of all maintenance-related work orders in the inspection, maintenance and repair plan. Said records and inspection reports shall be retained for a minimum of five years. (Retention time is not addressed in N.J.A.C. 7:8, but five years is required for retention of data collected for monitoring under a NJPDES permit.)
The person responsible for inspection, maintenance and repair identified under Subsection B(2) above shall submit the updated inspection, maintenance and repair plan and the documentation required by Subsections B(2) and B(3) above to the Township of Washington once per year. A written schedule of dates by which yearly inspections must take place must be prepared and submitted by the design engineer to the Township of Washington Engineer. The review of the updated inspection, maintenance and repair reports shall be reviewed by the Township Engineer as soon as practicable upon the receipt of such reports by the design engineer. Copies of said reports shall be maintained by the Township Engineer and the Township Clerk's office, together with any written reviews by the Township Engineer of said reports.
The person responsible for inspection, maintenance and repair identified under Subsection B(2) above shall retain and make available upon request by any public entity with administrative, health, environmental or safety authority over the site the inspection, maintenance and repair plan and the documentation required by Subsections B(2) and B(3) above.
In the event that the stormwater management measure becomes a public health nuisance or danger to public safety or public health, or if it is in need of maintenance or repair, the Township of Washington shall so notify the responsible person in writing. Upon receipt of that notice, the responsible person shall have 14 days to effect maintenance and repair of the facility in a manner that is approved by the Municipal Engineer or the Municipal Engineer's designee. The Township of Washington, at its discretion, may extend the time allowed for effecting maintenance and repair for good cause. If the responsible person fails or refuses to perform such maintenance and repair within the allowable time, the Township of Washington may immediately proceed to do so with its own forces and equipment and/or through contractors. The costs and expenses of such maintenance and repair by the Township of Washington shall be entered on the tax roll as a special charge against the property and collected with any other taxes levied thereon for the year in which the maintenance and repair was performed.
Additionally, for those stormwater management measures that are to be inspected, maintained and repaired by a public agency, the Township of Washington shall collect an upfront fee from the applicant in the amount the Township of Washington determines is needed to provide long-term inspection, maintenance and repair of all stormwater management measures. This upfront fee shall be placed in a dedicated cash management account and expended by the Township of Washington for the sole purpose of conducting inspection, maintenance and repair activities for all stormwater management measures required under the applicant's major development application approval. The calculation of the fee shall be based upon the inspection, maintenance and repair plan (plan) required to be prepared by the applicant and approved by the Township of Washington. The plan shall include an estimate of the present value of the cost to inspect, maintain and repair the stormwater management measure(s) in accordance with the plan for the useful life of those measure(s). The Township of Washington shall furnish the applicant its published hourly rates as prescribed by its salary ordinance for public works and other personnel having responsibilities associated with stormwater management. Added to this fee shall be an amount mutually determined by the Township of Washington and the applicant to account for the reconstruction of stormwater management measures that are reasonably anticipated to be subject to long-term failure. After an agreed number of years, depending on the type of measure(s), the measure(s) will need to be reconstructed. The amount shall be based on the future value of the measure(s) being reconstructed. Both inflation rates and bank interest rates shall be based on the ten-year average published in the Wall Street Journal or other approved publication. Interest accruing in the account must also be accounted for at an agreed upon interest rate to arrive at an amount. The costs for reconstructing the measure(s) shall be taken from the engineer's probable cost estimate that is utilized to determine the amount of the required performance guarantee. It is acceptable to attach a percentage of failure to certain line items in the estimate.
Additionally, for those stormwater management measures that are to be inspected, maintained and repaired by a homeowners' association, condominium association or some other form of nonpublic ownership, no fee shall be collected by the Township of Washington. Instead, the ownership entity shall establish and maintain a fund for the annual inspection and testing program, annual maintenance and repair program and annual contribution to a contingency fund for long-term reconstruction. The initial costs agreed to for the annual inspection and testing program and annual maintenance and repair program shall be based upon actual itemized proposals offered to the applicant by prospective vendors. The annual cost expended on inspection, testing and maintenance shall be reported to the Township of Washington to verify that maintenance is not being deferred and to inform the Township of Washington on the magnitude of those services. The contingency fund shall require sufficient funds to be committed for long-term reconstruction of the stormwater management measure(s). Major reconstruction activities will necessitate proper financial planning. After an agreed number of years, depending on the type of measure(s), the measure(s) will need to be reconstructed. The contingency fund in the financial schedule shall be based on the future value of the measure being reconstructed. Both inflation rates and bank interest rates shall be based on the ten-year average published in the Wall Street Journal or other approved publication. Interest accruing in the account must also be accounted for at an agreed upon interest rate, to arrive at an annual contribution amount.
An area or feature which is of significant environmental value, including but not limited to: stream corridors; natural heritage priority sites; habitat of endangered or threatened animal species; threatened or endangered plants of the Pinelands pursuant to N.J.A.C. 7:5-6.27(a); large areas of contiguous open space or upland forest; steep slopes; and wellhead protection and groundwater recharge areas.

Those lands which are inundated or saturated by water at a magnitude, duration and frequency sufficient to support the growth of hydrophytes. Wetlands include lands with poorly drained or very poorly drained soils as designated by the National Cooperative Soils Survey of the Soil Conservation Service of the United States Department of Agriculture. Wetlands include coastal wetlands and inland wetlands, including submerged lands. The New Jersey Pinelands Commission Manual for Identifying and Delineating Pinelands Area Wetlands: A Pinelands Supplement to the Federal Manual for Identifying and Delineating Jurisdictional Wetlands, dated January 1991, as amended, may be utilized in delineating the extent of wetlands based on the definitions of wetlands and wetlands soils contained in this section, N.J.A.C. 7:50 2.11, 6.4 and 6.5. The term "wetland" shall have the same meaning as "wetlands."
The general penalty provision of § 1-4, General penalty, shall apply regarding any and all violations of this Stormwater Control Ordinance.
NJDEP Nonstructural Strategies Point System. The New Jersey Stormwater Management Rules at N.J.A.C. 7:8-5.2(a), and § 214-4A of this chapter, require nonstructural stormwater management strategies to be incorporated into the site design of a major development. A total of nine strategies are to be used to the maximum extent practical to meet the groundwater recharge, stormwater quality stormwater quantity requirements of the rules prior to utilizing structural stormwater and management measures. The New Jersey Nonstructural Stormwater Management Strategies Point System (NSPS) provides a tool to assist planners, designers and regulators in determining that the strategies have been used to the "maximum extent practical" at a major development as required by the rules. Refer online to hhtp://www.njstrmwater.org for information on the NSPS.
A particle size category consisting of mineral particles which are smaller than 0.002 millimeters in equivalent spherical diameter. Also, a soil textural class having more than 40% clay, less than 45% sand, and less than 40% silt, as shown in § 214-11C(1) (USDA Soil Textural Triangle).
A soil textural class having 27 to 40% clay and 20 to 45% sand, as shown in § 214-11C(1) (USDA Soil Textural Triangle).
A soil textural class, as shown in § 214-11C(1) (USDA Soil Textural Triangle), that has a maximum of 85 to 90% sand with a percentage of silt plus 1.5 times the percentage of clay not in excess of 15; or a minimum of 70 to 85% sand with a percentage of silt plus 1.5 times the percentage of clay not in excess of 30.
A color pattern observed in soil, consisting of blotches or spots of contrasting color. The term "mottle" refers to an individual blotch or spot. The terms "color variegation," "iron depletion" and "iron concentration" are equivalent to the term "mottling." Mottling due to redoximorphic reactions is an indication of seasonal or periodic and recurrent saturation.
A soil textural class having 35% or more of clay and 45% or more of sand, as shown in § 214-11C(1) (USDA Soil Textural Triangle).
A soil textural class, as shown in § 214-11C(1) (USDA Soil Textural Triangle), that has a maximum of 20% clay, and the percentage of silt plus twice the percentage of clay exceeds 30, and contains 52% or more sand; or less than 7% clay, less than 50% silt, and between 43% and 52% sand.
A particle size category consisting of mineral particles which are between 0.002 and 0.05 millimeters in equivalent spherical diameter. It also means a soil textural class having 80% or more of silt and 12% or less of clay, as shown in § 214-11C(1) (USDA Soil Textural Triangle).
A soil textural class having 50% or more of silt and 12% to 27% of clay; or 50% to 80% of silt and less than 12% of clay, as shown in § 214-11C(1) (USDA Soil Textural Triangle).
A soil textural class having 40% or more of clay and 40% or more of silt, as shown in § 214-11C(1) (USDA Soil Textural Triangle).
A soil textural class having 27% to 40% of clay and less than 20% of sand, as shown in § 214-11C(1) (USDA Soil Textural Triangle).
The system of classifying soil texture used by the United States Department of Agriculture which defines 12 soil textural classes based upon the weight percentages of sand, silt and clay in that portion of the soil which passes through a sieve with two-millimeter openings. The soil textural classes are shown graphically on the USDA Soil Textural Triangle, as shown in § 214-11C(1).
All soil test pits and soil permeability results shall be performed under the direct supervision of a professional engineer. All soil logs and permeability test data shall be accompanied by a certification by a professional engineer. The results and location (horizontal and vertical) of all soil test pits and soil permeability tests, both passing and failing, shall be reported to the Township of Washington.
During all subsurface investigations and soil test procedures, adequate safety measures shall be taken to prohibit unauthorized access to the excavations at all times. It is the responsibility of persons performing or witnessing subsurface investigations and soil permeability tests to comply with all applicable federal state and local laws and regulations governing occupational safety.
The minimum acceptable tested permeability rate of any soil horizon or substratum shall be one inch per hour. Soil materials that exhibit tested permeability rates slower than one inch per hour shall be considered unsuitable for stormwater infiltration. The maximum reportable "tested permeability rate" of any soil horizon or substratum shall be no greater than 20 inches per hour regardless of the rate attained in the test procedure.
A groundwater mounding analysis shall be provided for each stormwater infiltration BMP. The groundwater mounding analysis shall calculate the maximum height of the groundwater mound based upon the volume of the maximum design storm. The professional engineer conducting the analysis shall provide the Municipal Engineer with the methodology and supporting documentation for the mounding analysis used and shall certify to the Township of Washington, based upon the analysis, that the groundwater mound will not cause stormwater or groundwater to break out to the land surface or cause adverse impact to adjacent surface water bodies, wetlands or subsurface structures, including but not limited to basements and septic systems. If there is more than one infiltration BMP proposed, the model shall indicate if and how the mounds will interact. The mounding analysis shall be calculated using the most restrictive soil horizon that will remain in place within the explored aquifer thickness unless alternative analyses is authorized by the Municipal Engineer. The mounding analysis shall be accompanied by a cross section of the infiltration BMP and surrounding topography, and the mound analysis shall extend out to the point(s) at which the mound intersects with the preexisting maximum water table elevation.
The applicant shall demonstrate that stormwater infiltration BMPs meet the seventy-two-hour drain time requirement established in § 214-5B(1) of this chapter.
Where flows from the water quality design storm as specified in § 214-3 are conveyed through any device (e.g., end-of-pipe netting facility, manufactured treatment device, or a catch basin hood) that is designed, at a minimum, to prevent delivery of all solid and floatable materials that could not pass through one of the following:
Where flows are conveyed through a trash rack that has parallel bars with one-inch spacing between the bars, to the elevation of the water quality design storm as specified in § 214-3 of this chapter; or
