[HISTORY: Adopted by the Township Committee of the Township of Mantua 12-13-2006 by Ord. No. O-19-2006 (Ch. 131A of the 1978 Code). Amendments noted where applicable.]
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 Mantua (hereinafter "Township").
The Township'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, including good water quality and natural rates and volumes of flow.
It is in the public interest to regulate the discharge of stormwater runoff from "major development" projects, as defined in § 344-7 of this chapter, conducted within the Township, 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.
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 Township, to protect public health and to enhance the domestic, municipal, recreational, industrial and other uses of water; and
All site plans and subdivisions for major developments occurring within the Township that require preliminary or final site plan or subdivision review; and
All major development projects undertaken by the Township shall comply with this chapter.
Procedures. In addition to other development review procedures set forth in the Code of the Township, major developments located within the Township 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 § 344-7 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. 7:8-5.4(b).
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 is a part, the stormwater provisions of such a plan(s) shall be adopted by the Township within one year of the adoption of a regional stormwater management plan (RSWMP) as an amendment to an areawide water quality management plan.
Whenever an applicant seeks municipal approval of a site development that is subject to this chapter, the applicant shall submit all of the required components of the checklist for the site development stormwater plan at § 344-2C below as part of the applicant's application for subdivision or site plan approval.

If more than one land cover, other than woods, has existed on the site during the five years immediately prior to the time of application, the land cover with the lowest runoff potential (including woods) shall be used for the computations. All predeveloped land covers shall be assumed to be in good hydrologic condition and, if cultivated, shall be assumed to have conservation treatment.
To the maximum extent practicable, the performance standards in § 344-4 for major development shall be met by incorporating the nine nonstructural strategies identified in Subchapter 5 of the New Jersey Stormwater Management Rules (N.J.A.C. 7:8-5), and set forth in § 344-2C(4)(a), into the design. The applicant shall identify within the land use planning and source control plan required by § 344-2C(4) of this chapter how each of the nine nonstructural measures will be incorporated into the design of the project to the maximum extent practicable.
If the applicant contends that it is not practical, for engineering, environmental or safety reasons, to incorporate any of the nine nonstructural strategies into the design of a particular project, the applicant shall provide a detailed rationale establishing a basis for the contention that use of the strategy is not practical on the site. This rationale shall be submitted in accordance with the checklist requirements established by § 344-2 to the Township. A determination by the Township that this rationale is inadequate or without merit shall result in a denial of the application unless one of the following conditions is met:
The land use planning and source control plan is amended to provide an alternative nonstructural strategy or measure that is not included in the list of nine nonstructural measures but still meets the performance standards in § 344-4, and the amended plan is approved by the Township; or
In addition to all other requirements of this section, each applicant shall demonstrate that, at a minimum, existing trees and vegetation on the development site will be preserved, protected and maintained according to the minimum standards established by provisions of the Township Land Use Ordinance, Zoning Ordinance or by conditions of zoning or variance approval.[1] Existing trees and vegetation shall be protected during construction activities in accordance with the standard for tree protection during construction provided in the New Jersey State Soil Conservation Committee Standards for Soil Erosion and Sediment Control in New Jersey, which is incorporated herein by reference, as amended and supplemented.

Guidance for nonstructural stormwater management strategies is available in the New Jersey BMP Manual, which may be obtained from the address identified in § 344-7A or found on the NJDEP's website at www.njstormwater.org.
Exception for major development sites creating less than one acre of disturbance. The use of nonstructural strategies to meet the performance standards in § 344-4 of this chapter is not required for major development creating less than one acre of disturbance. However, the following requirements shall be met:
Each applicant shall demonstrate that, at a minimum, existing trees and vegetation on the development site will be preserved and protected according to the minimum standards established by provisions of the Township Land Use Ordinance, Zoning Ordinance or by conditions of zoning or variance approval; and[2]
The design engineer, using the assumptions and factors for stormwater runoff and groundwater recharge calculations contained in § 344-3, shall either:
Demonstrate through hydrologic and hydraulic analysis that the post-developed stormwater runoff hydrographs from the project site for the two- , ten- , and one-hundred-year storms do not exceed, at any point in time, the site's predeveloped runoff hydrographs for the same storms.
There is no increase in predeveloped stormwater runoff rates from the project site for the two- , ten- , and one-hundred-year storms; and
Any increased stormwater runoff volume or change in stormwater runoff timing for the two- , ten- , and one-hundred-year storms will not increase flood damage at or downstream of the project site. When performing this analysis for predeveloped site conditions, all off-site development levels shall reflect existing conditions. When performing this analysis for post-developed site conditions, all off-site development levels shall reflect full development in accordance with current zoning and land use ordinances.
Demonstrate that the peak post-developed stormwater runoff rates from the project site for the two- , ten- , and one-hundred-year storms are 50%, 75% and 80%, respectively, of the site's peak predeveloped stormwater runoff rates for the same storms. Peak outflow rates from on-site stormwater measures for these storms shall be adjusted where necessary to account for the discharge of increased stormwater runoff rates and/or volumes from project site areas not controlled by the on-site measures. These percentages do not have to be applied to those portions of the project site that are not proposed for development at the time of application, provided that such areas are:
The standards for stormwater runoff quantity and rate required by this section shall be met using the methods, calculations and assumptions provided in § 344-3.
For all major developments, with the exception of those described in § 344-4C(4), below, the design engineer, using the assumptions and factors for stormwater runoff and groundwater recharge calculations contained in § 344-3, shall either:
Demonstrate through hydrologic and hydraulic analysis that any increase in the project site's stormwater runoff volume for the two year, twenty-four-hour storm from predeveloped to post-developed conditions is infiltrated on site.
The standards for groundwater recharge required by this section shall be met using the methods, calculations and assumptions provided in § 344-3.
The preceding groundwater recharge standards shall not apply to projects within the "urban redevelopment area," or to projects subject to Subsection C(3)(c) below.
The standards for stormwater runoff quality required by this section shall be met using the methods, calculations, assumptions and pollutant removal rates provided in § 344-3.
The TSS reduction requirement in § 344-4E(1) shall not apply to any stormwater runoff in a discharge regulated under a numeric effluent limitation for TSS imposed under the NJPDES rules (N.J.A.C. 7:14A) or in a discharge specifically exempt under a NJPDES permit from this requirement.
The stormwater runoff quantity and rate standards in § 344-4B shall still be met for all major development sites.
The Township 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. 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.
The applicant demonstrates that mitigation, in addition to the requirements of a mitigation plan discussed in Subsection G(1)(b) above, will be provided, consistent with one of the following options:
Mitigation may be provided off site but within the Township 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 Township in accordance with the following:
The amount of the in-lieu contribution shall be determined by the Township, 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 Township within the same drainage area as the development site and shall meet or exceed the equivalent recharge, quality or quantity performance standards which is lacking on the development site. Such mitigation project shall be identified by the Township in the Township's adopted municipal stormwater management plan. The stormwater control project to which the monetary contribution will be applied shall be identified by the Township at the time the exception is granted. The applicant shall amend the project description and site plan required in § 344-2C(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 Township 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 Township fail to expend the in-lieu contribution within the required time frame, the mitigation option provided in § 344-4G(1)(c) of this chapter shall be void and the Township shall be prohibited from collecting in-lieu contributions.
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 § 344-5 of this chapter.
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 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 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 § 344-10C(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 § 344-10C(3) of this chapter;
If the results of the postdevelopment field permeability tests fall to achieve the minimum required design permeability rates in Subsection B(3) 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 § 344-7, of all stormwater infiltration BMPs. The mounding analysis shall be conducted in accordance with the requirements in § 344-10C(3)(l). Where the mounding analysis identifies adverse impacts, the stormwater infiltration BMP shall be redesigned or relocated, as appropriate.
Unless the conditions in Subsection B(8)(a)[2] below are met, a stormwater infiltration BMP shall not be placed into operation until its drainage area is completely stabilized. Instead, upstream runoff shall be diverted around the BMP and into separate, temporary stormwater management facilities and sediment basins. Such temporary facilities and basins shall be installed and utilized for stormwater management and sediment control until stabilization is achieved in accordance with the Standards for Soil Erosion and Sediment Control in New Jersey, which is incorporated herein by reference, as amended and supplemented.
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. 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 § 344-4.
To avoid compaction of subgrade soils of BMPs that rely on infiltration, no heavy equipment such as backhoes, dump trucks or bulldozers shall be permitted to operate within the footprint of the BMP. All excavation required to construct a stormwater infiltration BMP shall be performed by equipment placed outside the BMP. If this is not possible, the soils within the excavated area shall be renovated and tilled after construction is completed to reverse the effects of compaction. In addition, postdevelopment soil permeability testing shall be performed in accordance with Subsection B(4) of this section.
Applicability. Projects subject to review pursuant to § 344-1C of this chapter shall comply with the requirements of Subsections B 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 § 344-2C. 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)(e) 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.
If the person responsible for inspection, maintenance and repair identified under Subsection B(2)(e) above is not a public agency, the maintenance plan and any future revisions based on Subsection B(6) below shall be recorded upon the deed of record for each property on which the maintenance described in the maintenance plan shall be undertaken.
The person responsible for inspection, maintenance and repair identified under Subsection B(2)(e) above shall evaluate the effectiveness of the inspection, maintenance and repair plan at least once per year and update the plan and the deed as needed.
The person responsible for inspection, maintenance and repair identified under Subsection B(2)(e) 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 once per year.
The person responsible for inspection, maintenance and repair identified under Subsection B(2)(e) 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.
Additionally, for those stormwater management measures that are to be inspected, maintained and repaired by a public agency, the Township shall collect an upfront fee from the applicant in the amount the Township 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 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. 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 shall furnish the applicant their published hourly rates as prescribed by their 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 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 be 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. 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 New Jersey Stormwater Management Rules at N.J.A.C. 7:8-5.2(a), and § 344-4A 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 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.
Definitions. For the purposes of this appendix, the following terms shall have the meanings herein ascribed to them:
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 § 344-10C(1) (USDA Soil Textural Triangle).
A soil textural class having 27% to 40% clay and 20% to 45% sand, as shown in § 344-10C (USDA Soil Textural Triangle).
Of a particle, the diameter of a sphere which has a volume equal to the volume of the particle.
A soil textural class, as shown in § 344-10C(1) (USDA Soil Textural Triangle), that has a maximum of 85% to 90% sand with a percentage of silt plus 1 1/2 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 1/2 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 § 344-10C(1) (USDA Soil Textural Triangle).
A soil textural class, as shown in § 344-10C(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 millimeters 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 § 344-10C(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 § 344-10C(1) (USDA Soil Textural Triangle).
A soil textural class having 40% or more of clay and 40% or more of silt, as shown in § 344-10C(1) (USDA Soil Textural Triangle).
A soil textural class having 27% to 40% of clay and less than 20% of sand, as shown in § 344-10C(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 § 344-10C(1).
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, 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 § 344-5B(1) of this chapter.
Where flows from the water quality design storm as specified in § 344-3 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 § 344-3 of this chapter; or
