Chapter 311 Stormwater Management
[HISTORY: Adopted by the Mayor and Council of the Borough of Atlantic Highlands 10-24-2007 by Ord. No. 23-2007. Amendments noted where applicable.]
Policy statement. Flood control, groundwater recharge and pollutant reduction through nonstructural or low-impact techniques shall be explored before relying on structural best management practice (BMPs). Structural BMPs should be integrated with nonstructural stormwater management measures and proper maintenance plans. Nonstructural measures include both environmentally sensitive site design and source controls that prevent pollutants from being placed on the site or from being exposed to stormwater. Source control plans should be developed based upon physical site conditions and the origin, nature, and the anticipated loading of potential pollutants. Multiple stormwater BMP methods may be necessary to achieve the established performance standards for water quality, quantity and groundwater recharge.
Purpose. It is the purpose of this chapter to establish minimum stormwater management requirements and controls for major development as defined in § 311-12.
Applicability. This chapter shall be applicable to any site plan or subdivision that requires preliminary or final site plan review, and to all major developments undertaken by Atlantic Highlands. No variances, waivers or special exceptions shall be granted without the express approval of the New Jersey Department of Environmental Protection (Department).
Compatibility with other permit and ordinance requirements. Development approvals issued pursuant to this chapter are to be considered an integral part of development approvals under the subdivision and site plan review process and do not relieve the applicant of the responsibility to secure required permits or approvals for activities regulated by any other applicable code, rule, act or ordinance. In their interpretation and application, the provisions of this chapter shall be held to be the minimum requirements for the promotion of the public health, safety, and general welfare. This chapter 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 chapter imposes restrictions different from those imposed by any other ordinance, rule or regulation, or other provision of law, the more restrictive provisions or higher standards shall control.
Stormwater management measures for major development shall be developed to meet the erosion control, groundwater recharge, stormwater runoff quantity, and stormwater runoff quality standards in this chapter unless such development or other measures are otherwise not permitted under § 150-78, Steep slopes, of Chapter 150, Development Regulations.[1] To the maximum extent feasible, these standards shall be met by incorporating nonstructural stormwater management strategies into the design. If these strategies alone are not sufficient to meet these standards, structural stormwater management measures necessary to meet these standards shall be incorporated into the design.
Note: The Borough Steep Slope Ordinance 943-89, as amended, was upheld by the New Jersey Supreme Court in Rumson Estates Inc. (Ferraro Builders) v. Borough of Fair Haven (Atlantic Highlands), 176 N.J. 250 (2003). The areas protected by the Steep Slope Ordinance have been identified by the United States Geologic Survey as a geologic hazard area. See Geological Survey Professional Paper 898, U.S. Government Printing Office, Washington, DC 1974.
For site improvements regulated under the Residential Site Improvement Standards (RSIS) at N.J.A.C. 5:21, the RSIS shall apply in addition to this chapter except to the extent the RSIS are superseded by this chapter or alternative standards applicable under a regional stormwater management plan or Water Quality Management Plan adopted in accordance with Department rules.
The development shall incorporate a maintenance plan and designate a responsible party for the stormwater management measures incorporated into the design of a major development.
The construction of an underground utility line provided that the disturbed areas are revegetated upon completion.
The construction of an aboveground utility line, provided that the existing conditions are maintained to the maximum extent practicable.
The construction of a public pedestrian access, such as a sidewalk or trail with a maximum width of 10 feet, provided that the access is made of permeable material.
The applicant demonstrates that it does not own or have other rights to areas, including the potential to obtain through condemnation lands not falling under Subsection D above within the upstream drainage area of the receiving stream, that would provide additional opportunities to mitigate for requirements of Subsections F and G that were not achievable on-site.
To the maximum extent practicable, the standards in Subsections F and G shall be met by incorporating nonstructural stormwater strategies set forth at Subsection E into the design. The applicant shall identify the nonstructural measures incorporated into the design of the project. If the applicant contends that it is not feasible for engineering, environmental, or safety reasons to incorporate any nonstructural stormwater management measures identified in Subsection E(2) below into the design of a particular project, the applicant shall identify the measures considered and provide a basis for the contention. The applicant shall be aware that areas defined as steep slopes and protected by § 150-78, Steep slopes, of Chapter 150, Development Regulations, have been identified by the United States Geologic Survey as a geologic hazard area (Geological Survey Professional Paper 898, U.S. Government Printing Office, Washington, 1974).[1] Increasing groundwater recharge and/or infiltration in the steep slopes section increases the geologic hazard to the detriment of the public interest and welfare and is not permitted.
Provide low-maintenance native plant landscaping that maximizes retention of existing native vegetation and planting of native vegetation and minimizes the use of lawns and need for fertilizers and pesticides;
Examples of grates subject to this standard include grates in grate inlets, the grate portion (non-curb-opening portion) of combination inlets, grates on storm sewer manholes, ditch grates, trench grates, and grates of space bars in slotted drains. Examples of ground surfaces include surfaces of roads (including bridges), driveways, parking areas, bikeways, plazas, sidewalks, lawns, fields, open channels, and stormwater basin floors.
Where flows from the water quality design storm as specified in Subsection G(1) are conveyed through any device (e.g., end-of-pipe netting facility, manufactured treatment device, or a catch basin hood) that is designated, at a minimum, to prevent delivery of all solid and floatable materials that could not pass through one of the following:
Any land area used as a nonstructural stormwater management measure to meet the performance standards in Subsections F and G shall be dedicated through deed to a government agency, subjected to a conservation deed restriction filed with the appropriate County Clerk's office, or subject to an approved equivalent restriction that ensures the maintenance of that measure in perpetuity.
Guidance for nonstructural stormwater management measures is available in the New Jersey Stormwater Best Management Practices Manual. The manual is available on the Department's web page at http://www.njstormwater.org or www.njnonpointsource.org.
Except if Subsection F(2), (3) or (4) apply, the design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations of § 311-4, either:
This groundwater recharge requirement does not apply to projects that qualify as "urban redevelopment."
Stormwater from areas of high pollutant loading. "High-pollutant loading areas" are areas in industrial and commercial developments where solvents and/or petroleum products are loaded/unloaded, stored, or applied, areas where pesticides are loaded/unloaded or stored; areas where hazardous materials are expected to be present in greater than reportable quantities as defined by the United States Environmental Protection Agency (EPA) at 40 CFR 302.4; areas where recharge would be inconsistent with a Department approved remedial action work plan or landfill closure plan and areas with high risks for spills of toxic materials, such as gas stations and vehicle maintenance facilities; and
Where it's a hazard and not permitted as outlined in § 150-78, Steep slopes, of Chapter 150, Development Regulations (the AH Steep Slopes Ordinance # 943-89 as amended # 14-96), upheld by the NJ Supreme Court (in the case of Ferraro Builders, LLC and Rand Associates, a New Jersey Partnership v. Borough of Atlantic Highlands Planning Board and Borough of Atlantic Highlands decided August 5, 2003), and has been identified by the United States Geologic Survey as a geologic hazard area (Geological Survey Professional Paper 898, US Government Printing Office, Washington, 1974).[2]
In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations of § 311-4, complete one of the following:
Design stormwater management measures so that the postconstruction peak runoff rates for the two-, ten-, and one-hundred-year storm events are 50%, 75% and 80%, respectively, of the preconstruction peak runoff rates. The percentages apply only to the postconstruction stormwater runoff that is attributable to the portion of the site on which the proposed development or project is to be constructed. The percentages shall not be applied to postconstruction stormwater runoff into tidal flood hazard areas if the increased volume of stormwater runoff will not increase flood damages below the point of discharge;
Any application for a new agricultural development that meets the definition of major development at § 311-12 shall be submitted to the appropriate Soil Conservation District for review and approval in accordance with the requirements of this section and any applicable Soil Conservation District guidelines for stormwater runoff quantity and erosion control.
For purposes of TSS reduction calculations, Table 2 below presents the presumed removal rates for certain BMPs designed in accordance with the New Jersey Stormwater Best Management Practices Manual, which may be obtained from the address identified in § 311-6. TSS reduction shall be calculated based on the removal rates for the BMPs in Table 2 below. Alternative removal rates and methods of calculating removal rates may be used if the design engineer provides documentation demonstrating the capability of these alternative rates and methods to the review agency. A copy of any approved alternative rate or method of calculating the removal rate shall be provided to the Department at the following address: Division of Watershed Management, New Jersey Department of Environmental Protection, P.O. Box 418, Trenton, New Jersey, 08625-0418.
Total TSS load removal from application of both BMPs
The TSS removal rate applicable to the first BMP
The TSS removal rate applicable to the second BMP
See N.J.A.C. 7:8-5.7(c)
Stormwater management measures shall also be designed to reduce, to the maximum extent feasible, the postconstruction nutrient load from the developed site in stormwater runoff generated from the water quality design storm. In achieving reduction of nutrients to the maximum extent feasible, the design of the site shall include nonstructural strategies and structural measures that optimize nutrient removal while still achieving the performance standards in Subsections F and G.
Additional information and examples are contained in the New Jersey Stormwater Best Management Practices Manual, which may be obtained from the address identified in § 311-6.
In accordance with the definition of FW1 at N.J.A.C. 7:9B-1.4, stormwater management measures shall be designed to prevent any increase of stormwater to waters classified as FW1.
Special water resource protection areas shall be established along all waters designated Category One of N.J.A.C. 7:9B and perennial or intermittent streams that drain into or upstream of the Category One waters as shown on the USGS Quadrangle Maps or in the County Soil Surveys, within the associated HUC 14 drainage. These areas shall be established for the protection of water quality, aesthetic value, exceptional ecological significance, exceptional recreational significance, exceptional water supply significance, and exceptional fisheries significance of those established Category One waters. These areas shall be designated and protected as follows:
A three-hundred-foot special water resource protection area shall be provided on each side of the waterway, measured perpendicular to the top of the bank of the waterway or center line of the waterway where the bank is undefined, consisting of existing vegetation or vegetation allowed to follow natural succession.[3]
Encroachment within the designated special water resource protection area under Subsection G(8)(a)[1] above shall only be allowed where previous development or disturbance has occurred (for example, active agricultural use, parking area or maintained lawn area). The encroachment shall only be allowed where applicant demonstrates that the functional value and overall condition of the special water resource protection area will be maintained to the maximum extent practicable. In no case shall the remaining special water resource protection area be reduced to less than 150 feet as measured perpendicular to the top of the bank of the waterway or center line of the waterway where the bank is undefined. All encroachments proposed under this subsection shall be subject to review and approval by the Department.
The USDA Natural Resources Conservation Service (NRCS) methodology, including the NRCS Runoff Equation and Dimensionless Unit Hydrograph, as described in the NRCS National Engineering Handbook, Section 4, Hydrology and Technical Release 55 - Urban Hydrology for Small Watersheds; or
For the purpose of calculating runoff coefficients and groundwater recharge, there is a presumption that the preconstruction condition of a site or portion thereof is a wooded land use with good hydrologic condition. The term "runoff coefficient" applies to both the NRCS methodology Subsection A(1)(a) and the Rational and Modified Rational Methods at Subsection A(1)(b). A runoff coefficient or a groundwater recharge land cover for an existing condition may be used on all or a portion of the site if the design engineer verifies that the hydrologic condition has existed on the site or portion of the site for at least five years without interruption prior to the time of calculation. If more than one land cover have existed on the site during the five years immediately prior to the time of application, the land cover with the lowest runoff potential shall be used for the computations. In addition, there is the presumption that the site is in good hydrologic condition (if the land use type is pasture, lawn, or park), with good cover (if the land use type is woods), or with good condition and conservation treatment (if the land use type is cultivation).
In computing stormwater runoff from a design storm, the design engineer shall consider the relative stormwater runoff rates and/or volumes of pervious and impervious surfaces separately to accurately compute the rates and volume of stormwater runoff from the site. To calculate runoff from unconnected impervious cover, urban impervious area modifications as described in the NRCS Technical Release 55, Urban Hydrology for Small Watersheds, may be employed.
The New Jersey Geological Survey Report GSR-32 A Method for Evaluating Ground-Water Recharge Areas in New Jersey, incorporated herein by reference as amended and supplemented. Information regarding the methodology is available from the New Jersey Stormwater Best Management Practices Manual at http://www.state.nj.us/dep/njgs/; or at New Jersey Geological Survey, 29 Arctic Parkway, P.O. Box 427, Trenton, New Jersey 08625-0427; (609) 984-6587.
Structural stormwater management measures shall be designed to take into account the existing site conditions, including, for example, environmentally critical areas; wetlands; flood-prone areas; slopes; depth to seasonal high water table; soil type, permeability and texture; drainage area and drainage patterns; and the presence of solution-prone carbonate rocks (limestone). Section 150-78, Steep slopes, of Chapter 150, Development Regulations, as defined in (the AH Steep Slopes Ordinance, No. 943-89, as amended by Ord. No. 14-96), upheld by the NJ Supreme Court (Ferraro Builders, LLC and Rand Associates, a New Jersey Partnership v. Borough of Atlantic Highlands Planning Board and Borough of Atlantic Highlands decided August 5, 2003), has been identified by the United States Geologic Survey as a geologic hazard area (Geological Survey Professional Paper 898, U.S. Government Printing Office, Washington, 1974). Increasing groundwater recharge and/or infiltration in the § 150-78, Steep slopes, increases the geologic hazard to the detriment of the public interest and welfare and is not permitted.
Structural stormwater management measures shall be designed to minimize maintenance, facilitate maintenance and repairs, and ensure proper functioning. Trash racks shall be installed at the intake to the outlet structure as appropriate, and shall have parallel bars with one-inch spacing between the bars to the elevation of the water quality design storm. For elevations higher than the water quality design storm, the parallel bars at the outlet structure shall be spaced no greater than 1/3 the width of the diameter of the orifice or 1/3 the width of the weir, with a minimum spacing between bars of one inch and a maximum spacing between bars of six inches. In addition, the design of trash racks must comply with the requirements of § 311-7D.
Stormwater management basins shall be designed to meet the minimum safety standards for stormwater management basins of § 311-7.
Stormwater management measures shall be designed to drain rapidly to prevent their becoming breeding or reservoir areas for disease vectors.
Stormwater management measure guidelines are available in the New Jersey Stormwater Best Management Practices Manual. Other stormwater management measures may be utilized, provided the design engineer demonstrates that the proposed measure and its design will accomplish the required water quantity, groundwater recharge and water quality design and performance standards in § 311-7D(1), (2) and (3) for trash racks, overflow gates, and escape as established by this chapter.
Guidelines for stormwater management measures are contained in the New Jersey Stormwater Best Management Practices Manual, as amended. Information is provided on stormwater management measures such as: bioretention systems, constructed stormwater wetlands, dry wells, forested buffers, extended detention basins, infiltration structures, manufactured treatment devices, pervious paving, sand filters, vegetative filter strips, and wet ponds.

The provisions of this section are not intended to preempt municipal or county safety requirements for new or existing stormwater management basins. Municipal and county stormwater management plans and ordinances may, pursuant to their authority, require existing stormwater management basins to be retrofitted to meet one or more of the safety standards in Subsection D(1), (2) and (3) for trash racks, overflow grates, and escape provisions at outlet structures.
Operative date and compliance schedule.
For purposes of this subchapter, a stormwater management basin is "existing" if construction of such basin commenced prior to (one year from the effective date of this chapter), or if such basin was identified in a subdivision or site plan application that received final approval pursuant to the Municipal Land Use Law (N.J.S.A. 40:55D-1 et seq.) as of one year from the effective date of this chapter. Any other stormwater management basin is a "new" basin.
As of one year from the effective date of this chapter, the construction, installation, or operation of any new stormwater management basin that does not conform to the requirements of this section is prohibited.
If an existing stormwater management basin does not conform to a municipal or county stormwater control ordinance adopted pursuant to N.J.A.C. 7:8-6.1(c), the person responsible for the stormwater management basin under such ordinance shall, within the time period specified in the ordinance, modify the basin to comply with the ordinance.
If a stormwater management basin has an outlet structure, escape provisions shall be incorporated in or on the structure. With the prior approval of the reviewing agency identified in Subsection E, a freestanding outlet structure may be exempted from this requirement.
Safety ledges shall be constructed on the slopes of all new stormwater management basins having a permanent pool of water deeper than 2 1/2 feet. Such safety ledges shall be comprised of two steps. Each step shall be four feet to six feet in width. One step shall be located approximately 2 1/2 feet below the permanent water surface, and the second step shall be located one to 1 1/2 feet above the permanent water surface. See Subsection E for an illustration of safety ledges in a stormwater management basin.
Topographic base map. The reviewing engineer may require upstream tributary drainage system information as necessary. It is recommended that the topographic base map of the site be submitted which extends a minimum of 200 feet beyond the limits of the proposed development, at a scale of one inch equals 200 inches or greater, showing two-foot contour intervals. The map, as appropriate, may indicate the following: existing surface water drainage, shorelines, steep slopes, soils, erodible soils, perennial or intermittent streams that drain into or upstream of the Category 1 waters, wetlands and floodplains along with their appropriate buffer strips, marshlands and other wetlands, pervious or vegetative surfaces, existing man-made structures, roads, bearing and distances of property lines, and significant natural and man-made features not otherwise shown.
