Article III: Stormwater Control
[Adopted 10-11-2006 by Ord. No. 11-2006]
Chapter 164: Stormwater Management Article III Stormwater Control
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 Borough of Folsom and downstream municipalities.
Certain lands of the Borough of Folsom lie within the Pinelands Area, and therefore, development in this portion of Borough of Folsom is subject to the requirements of the Pinelands Protection Act (N.J.S.A. 13:18A-1 et seq.) and the implementing regulations and minimum standards contained in the Pinelands Comprehensive Management Plan (N.J.A.C. 7:50-1.1 et seq.) (CMP). The purpose and intent of these regulations and standards is to promote orderly development of the Pinelands so as to preserve and protect the significant and unique natural, ecological, agricultural, archaeological, historical, scenic, cultural and recreational resources of the Pinelands.
Pinelands Area resources are to be protected in accordance with Pinelands Comprehensive Management Plan at N.J.A.C. 7:50 et seq., 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 Pinelands, 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 Pinelands Area have the potential to adversely affect Borough of Folsom's streams and water resources and the streams and water resources of downstream municipalities.
Stormwater runoff, soil erosion and nonpoint-source pollution can be controlled and minimized through the regulation of stormwater runoff from development sites.
It is in the public interest to regulate the discharge of stormwater runoff from major development projects, as defined in § 164-18 of this article, conducted within the Pinelands Area, as provided in this article, 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 article to establish minimum stormwater management requirements and controls for major development, consistent with the statewide stormwater requirements at N.J.A.C. 7:8, the regulations and standards contained in the Pinelands CMP, and the provisions of the adopted Master Plan and land use ordinances of the Borough of Folsom.
Through this article, the Borough of Folsom has established the following goals for stormwater control:
To maintain the integrity of stream channels for their biological functions as well as for drainage;
To restore, protect, maintain and enhance the quality of the streams and water resources of Borough of Folsom and the ecological character and quality of the Pinelands Area;
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 and ground waters of the Borough of Folsom, 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 article, the Borough of Folsom has identified the following management techniques:
Compliance with the stormwater runoff quantity and rate, groundwater recharge, erosion control, and stormwater runoff quality standards established through N.J.A.C. 7:8-1.1 et seq., and this article shall be accomplished to the maximum extent practicable through the use of nonstructural BMPs, before relying on structural BMPs. Nonstructural BMPs are also known as low-impact development (LID) techniques.
All major development projects undertaken by the Borough of Folsom shall comply with this article.[1]
Note: This clause is intended to provide consistency with DEP's stormwater management requirements. As per normal practice, all development within the Pinelands Area which is undertaken by a Pinelands Area municipality shall comply with all of the requirements of the CMP.
Procedures. In addition to other development review procedures set forth in the Code of the Borough of Folsom, major developments located within the Pinelands Area shall comply with the stormwater management requirements and specifications set forth in this article. New agricultural development that meets the definition of major development in § 164-18 of this article 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 their interpretation and application, the provisions of this article shall be held to be the minimum requirements for the promotion of the public health, safety and general welfare. This article is not intended to interfere with, abrogate or annul any other ordinances, rule or regulation, statute or other provision of law except that, where any provision of this article imposes restrictions different from those imposed by any other ordinance, rule or regulation or other provision of law, the more restrictive or stringent provisions or higher standards shall control.
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 Borough of Folsom is a part, the stormwater provisions of such a plan(s) shall be adopted by Folsom within one year of the adoption of a regional stormwater management plan (RSWMP) as an amendment to an areawide water quality management plan. Local ordinances proposed to implement the RSWMP shall be submitted to the Commission for certification within six months of the adoption of the RSWMP per N.J.A.C. 7:8 and the Pinelands CMP (N.J.A.C. 7:50).

Exceptions from strict compliance from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements established by this article may be granted, at the discretion of the Borough of Folsom and subject to approval by the Pinelands Commission, provided that all of the following conditions are met:
The exception is consistent with that allowed by the Borough of Folsom;
The Borough of Folsom has an adopted and effective municipal stormwater management plan in accordance with N.J.A.C. 7:8-4.4, which includes a mitigation plan in accordance with N.J.A.C. 7:8-4.2(c) 11, and is also certified by the Pinelands Commission. The mitigation plan shall identify what measures are necessary to offset the deficit created by granting the exception, and the municipality shall submit a written report to the county review agency and the NJDEP describing the exception, and the required mitigation. Guidance for developing municipal stormwater management plans, including mitigation plans, is available from the NJDEP, Division of Watershed Management, and the New Jersey BMP Manual.
Mitigation may be provided off site, but within the Pinelands Area and within the same drainage area as the development site, and shall meet or exceed the equivalent recharge, quality or quantity performance standard which is lacking on the development site due to the exception; or
In lieu of the required mitigation, a monetary in lieu contribution may be provided by the applicant to the Borough of Folsom in accordance with the following:
The amount of the in lieu contribution shall be determined by the Borough of Folsom, but the maximum in lieu contribution required shall be equivalent to the cost of implementing and maintaining the stormwater management measure(s) for which the exception is granted;
The in lieu contribution shall be used to fund an off-site stormwater control mitigation project(s) located within the Pinelands Area, within the same drainage area as the development site, and shall meet or exceed the equivalent recharge, quality or quantity performance standard which is lacking on the development site. Such mitigation project shall be identified by Folsom in the Borough of Folsom's adopted municipal stormwater management plan. The stormwater control project to which the monetary contribution will be applied shall be identified by the Borough of Folsom at the time the exception is granted. The applicant shall amend the project description and site plan required in § 164-13C(3) to incorporate a description of both the standards for which an on-site exception is being granted and of the selected off-site mitigation project.
The Borough of Folsom shall expend the in lieu contribution to implement the selected off-site mitigation project within five years from the date that payment is received. Should the Borough of Folsom fail to expend the in lieu contribution within the required time frame, the mitigation option provided in § 164-15H(1)(c)[3] of this article shall be void and the Borough of Folsom shall be prohibited from collecting in lieu contributions.
Structural stormwater management measures shall be designed to meet the standards established in this section. These standards have been developed to protect public safety, conserve natural features, create an aesthetically pleasing site and promote proper on site stormwater management.[1]
Note: Though not required by N.J.A.C. 7:8, pursuant to their authority, municipalities may have the option to require existing basins that pose a public health or safety hazard to be retrofitted to comply with the standards in this subsection.
The following structural stormwater management measures may be utilized as part of a stormwater management system at a major land development in the Pinelands, provided that the applicant demonstrates that they are designed, constructed and maintained so as to meet the standards and requirements established by this article. If alternative stormwater management measures are proposed, the applicant shall demonstrate that the selected measures will achieve the standards established by this article.
For all stormwater management measures at a development site, each applicant shall submit a detailed inspection, maintenance and repair plan consistent with the requirements of § 164-16 of this article.
Establishment of attractive landscaping in and around the basin that mimics the existing vegetation and incorporates native Pinelands plants, including, but not limited to, the species listed in N.J.A.C. 7:50-6.25 and 6.26.
After all construction activities and required field testing have been completed on the development site, as-built plans depicting design and as-built elevations of all stormwater management measures shall be prepared by a licensed land surveyor and submitted to the Municipal Engineer. 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 article and/or any reasons of public health or safety shall be completed by the applicant. In lieu of review by the Municipal Engineer, Folsom 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 minimum design permeability rate for the soil within a BMP that relies on infiltration shall be 1/2 inch per hour. A factor of safety of two shall be applied to the soil's field-tested permeability rate to determine the soil's design permeability rate. For example, if the field-tested permeability rate of the soil is four inches per hour, its design permeability rate would be two inches per hour. The minimum design permeability rate for the soil within a stormwater infiltration basin shall also be sufficient to achieve the minimum seventy-two-hour drain time described in Subsection B(1) above. The maximum design permeability shall be 10 inches per hour.
The predevelopment field test permeability rate shall be determined according to the methodologies provided in § 164-22C(3) of this article;
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 § 164-22C(3) of this article;
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 retested until such minimum required design permeability rates are achieved; and
The design engineer shall conduct a mounding analysis, as defined in § 164-18, of all stormwater infiltration BMPs. The mounding analysis shall be conducted in accordance with the requirements in § 164-22C(3)(l). Where the mounding analysis identifies adverse impacts, the stormwater infiltration BMP shall be redesigned or relocated, as appropriate.
If the design engineer determines that, for engineering, environmental or safety reasons, temporary stormwater management facilities and sediment basins cannot be constructed on the site, the stormwater infiltration basin may be placed into operation prior to the complete stabilization of its drainage area, provided that the basin's bottom during this period is constructed at a depth at least two feet higher than its final design elevation. All other infiltration BMP construction requirements in this section shall be followed.

NJDEP nonstructural strategies point system. The New Jersey Stormwater Management Rules at N.J.A.C. 7:8-5.2(a), and § 164-15A of this article, 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 and stormwater quantity requirements of the rules prior to utilizing structural stormwater 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 http://www.njstormwater.org for information on the NSPS.

The soil permeability rate shall be determined using test methodology as prescribed in N.J.A.C. 7:9A-6.2 (tube permeameter test), 6.5 (pit bailing test) or 6.6 (piezometer test). When the tube permeameter test is used, a minimum of two replicate samples shall be taken and tested. Alternative permeability test procedures may be accepted by the approving authority, provided the test procedure attains saturation of surrounding soils, accounts for hydraulic head effects on infiltration rates, provides a permeability rate with units expressed in inches per hour and is accompanied by a published source reference. Examples of suitable sources include hydrogeology, geotechnical or engineering text and design manuals, proceedings of American Society for Testing and Materials (ASTM) symposia, or peer-review journals. Neither a soil permeability class rating test, as described in N.J.A.C. 7:9A-6.3, nor a percolation test, as described in N.J.A.C. 7:9A-6.4, are acceptable tests for establishing permeability values for the purpose of complying with this article.
Soil permeability tests shall be conducted on the most hydraulically restrictive horizon or substratum to be left in place below the basin as follows: Where no soil replacement is proposed, the permeability tests shall be conducted on the most hydraulically restrictive horizon or substratum within four feet of the lowest elevation of the basin bottom or to a depth equal to two times the maximum potential water depth within the basin, whichever is greater. Where soil replacement is proposed, the permeability tests shall be conducted within the soil immediately below the depth of proposed soil replacement or within the most hydraulically restrictive horizon or substratum to a depth equal to two times the maximum potential water depth within the basin, whichever is greater. Permeability tests may be performed on the most hydraulically restrictive soil horizons or substrata at depths greater than those identified above, based upon the discretion of the design or testing engineer. The tested infiltration rate should then be divided by two to establish the soil's design permeability rate. Such division will provide a one-hundred-percent safety factor to the tested rate.
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 Borough of Folsom, 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.

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 § 164-14 of this article; or
Catch basins. Catch basins are storm drain inlets with or without sumps. Catch basins may provide pretreatment for other stormwater BMPs by capturing large sediments. The sediment and pollutant removal efficiency of catch basins depends on the size of the sump and the performance of routine maintenance to retain the available sediment storage space in the sump. Where catch basins with sumps are proposed, the minimum two-foot separation between the bottom of the sump and seasonally high water table shall be provided.
