Article XII Storm Drainage within Pinelands Regulated Areas
[Added 12-18-2006 by Ord. No. 2006-26]
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 Eagleswood Township.
Certain lands of Eagleswood Township lie within the Pinelands Area, and therefore, development in this portion of Eagleswood Township 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 the 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 Eagleswood Township'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 § 295-82 of this article, conducted within the Pinelands Area, 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, the regulations and standards contained in the Pinelands CMP, and the provisions of the adopted Master Plan and land use ordinances of Eagleswood Township.
Through this article, Eagleswood Township has established the following goals for stormwater control:
To restore, protect, maintain and enhance the quality of the streams and water resources of Eagleswood Township 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 waters and groundwaters of Eagleswood Township, 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, Eagleswood Township has identified the following management techniques:
Implementation of multiple stormwater management best management practices (BMPs) may be necessary to achieve the performance standards for stormwater runoff quantity and rate, groundwater recharge, erosion control and stormwater runoff quality established through this article.
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 site plans and subdivisions for major developments, as defined in § 295-61, occurring within the Pinelands Area that require preliminary or final site plan or subdivision review; and
All major development, as defined in § 295-61, projects undertaken by Eagleswood Township within the Pinelands Area shall comply with this article.
Procedures. In addition to other development review procedures set forth in the Code of Eagleswood Township, 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 § 295-82 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 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 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 Eagleswood Township is a part, the stormwater provisions of such a plan(s) shall be adopted by Eagleswood Township 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.)

This subsection applies to the following areas of a major development as defined in § 295-82 of this chapter:
For a major development in areas described in Subsection F(1)(a) or (b) above, in addition to the infiltration requirements specified in Subsection B(2) and the groundwater recharge requirements specified in Subsection C, the applicant shall demonstrate in the land use planning and source control plan required in § 295-77C(4) that the following requirements have been met:
The extent of the areas described in Subsection F(1)(a) and (b) above have been minimized on the development site to the maximum extent practicable;
The stormwater runoff from the areas described in Subsection F(1)(a) and (b) above is segregated to the maximum extent practicable from the stormwater runoff generated from the remainder of the site such that commingling of the stormwater runoff from the areas described in Subsection F(1)(a) and (b) above and the remainder of the site will be minimized;
The amount of precipitation falling directly on the areas described in Subsection F(1)(a) and (b) above is minimized to the maximum extent practicable by means of a canopy, roof or other similar structure that reduces the generation of stormwater runoff; and
The stormwater runoff from or commingled with the areas described in Subsection F(1)(a) and (b) above for the Water Quality Design Storm, defined in § 295-78B, Table 1, shall be subject to pretreatment by one or more of the following stormwater BMPs, designed in accordance with the New Jersey BMP Manual to provide ninety-percent TSS removal:
Wet ponds which shall be hydraulically disconnected by a minimum of two feet of vertical separation from the seasonal high-water table and shall be designed to achieve a minimum eighty-percent TSS removal rate;
If the potential for contamination of stormwater runoff by petroleum products exists on site, prior to being conveyed to the pretreatment BMP required in Subsection F(2)(d) above the stormwater runoff from the areas described in Subsection F(1)(a) and (b) above shall be conveyed through an oil/grease separator or other equivalent manufactured filtering device to remove the petroleum hydrocarbons. The applicant shall provide the reviewing agency with sufficient data to demonstrate acceptable performance of the device.
Threatened and endangered species and associated habitat standards. Stormwater management measures shall address the impacts of the development on habitat for threatened and endangered species, in accordance with N.J.A.C. 7:8-5.2(c), N.J.A.C. 7:50-6.27, 7:50-6.33 and 7:50-6.34.
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 Eagleswood Township, 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 Eagleswood Township;
Eagleswood 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 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.
The applicant demonstrates that mitigation, in addition to the requirements of the mitigation plan discussed in Subsection H(1)(b) above, will be provided consistent with one of the following options:
In lieu of the required mitigation, a monetary "in lieu contribution" may be provided by the applicant to Eagleswood Township in accordance with the following:
The amount of the in lieu contribution shall be determined by Eagleswood 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 Pinelands Area, within the same drainage area as the development site, and shall meet or exceed the equivalent recharge, quality or quantity performance standard(s) which is lacking on the development site. Such mitigation project shall be identified by Eagleswood 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 Eagleswood Township at the time the exception is granted. The applicant shall amend the project description and site plan required in § 295-77C(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.
Eagleswood 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 Eagleswood Township fail to expend the in lieu contribution within the required time frame, the mitigation option provided in Subsection H(1)(c)[2] of this section shall be void, and Eagleswood Township shall be prohibited from collecting in lieu contributions.
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 chapter.
Structural stormwater management measures shall be designed and constructed to be strong, durable and corrosion-resistant (measures that are consistent with the relevant portions of the Residential Site Improvement Standards at N.J.A.C. 5:21-7.3, 5:21-7.4 and 5:21-7.8 shall be deemed to meet this requirement), to minimize and facilitate maintenance and repairs and to ensure proper functioning.
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 this section 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 7:50-6.26.
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, Eagleswood 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 bioretention system is integrated into and made part of the infiltration BMP and, as such, does not require an underdrain system. If this option is selected, the infiltration BMP shall be designed and constructed so that the maximum water depth in the bioretention system portion of the BMP during treatment of the stormwater quality design storm is 12 inches, in accordance with the New Jersey BMP Manual.
The minimum design permeability rate for the soil within a BMP that relies on infiltration shall be 0.5 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 § 295-85C(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, post-development field permeability tests shall also be conducted according to the methodologies provided in § 295-85C(3) of this article;
If the results of the post-development 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 § 295-82, of all stormwater infiltration BMPs. The mounding analysis shall be conducted in accordance with the requirements in § 295-85C(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(9)(a)[2] below are met, a stormwater infiltration basin shall not be placed into operation until its drainage area is completely stabilized. Instead, upstream runoff shall be diverted around the basin 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, 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 § 295-79.
Storm drain pipe. The minimum size of storm drain pipe permitted shall be 15 inches, except that 18 inches' minimum shall be used for all pipes draining low points. All storm drain pipes shall be either gasketed slip-joint-type reinforced concrete or subject to the restrictions herein, fully coated, invert paved, corrugated steel culvert pipe meeting the requirements of the Standard Specifications and of a wall thickness sufficient to meet the proposed conditions of service, but in any event no wall thickness less than Class 3, Wall B, for concrete pipe or 14 gauge for corrugated steel pipe shall be allowed. Generally, concrete pipe will be used except in areas of steep grades or other restrictive physical conditions where corrugated or other types of pipe may be permitted. No concrete pipe may be laid on grades exceeding 10%. All concrete pipe will be jointed using a preformed bituminous mastic pressure-type joint sealer or rubber-ring-type or other equivalent approved joint. All corrugated pipe shall be fully bituminous coated with paved invert and of a gauge per manufacturer's data sufficient for the proposed service. Where conditions permit, corrugated aluminum storm drains may be substituted for corrugated steel storm drains where the same are otherwise permitted on the basis of an equivalent three-edge bearing or crushed strength. Substitution on an equivalent-gauge basis will not be allowed. Corrugated polyethylene pipe and ductile iron pipe shall also be permitted in accordance with RSIS. All storm drains shall be tangent between inlets, manholes or other structures, except that the use of fittings or factory-curved or mitered pipe may be allowed by the Township Engineer when necessary to accommodate existing geometry or utilities. Prior to laying any storm drains, the bottom of all trenches shall be inspected by the Township Engineer. Should the Engineer determine that the trench is unsuitable for placement of the pipe, the developer shall take all necessary action to remove or eliminate any unsuitable conditions. These may include, but are not limited to, excavation and backfilling with suitable material, placement of bedding material, construction of pipe cradles or such other action necessary to remove all unsuitable conditions. Proposed storm drainage installations which do not conform to the above must be fully detailed and approved as part of the final plat.
Headwalls. All pipe terminations shall be provided with poured-concrete headwalls, precast-concrete end sections or corrugated metal end sections in accordance with the approved final plat. Poured-concrete headwalls shall be wing-type headwalls with aprons in accordance with the standard construction details.

Structures (inlets or manholes) shall be located so as not to interfere with primary routes of pedestrian travel or any proposed handicapped ramp or similar facility.
In general, surface flow length, for flows of four or more cubic feet per second, on paved surfaces shall not exceed 400 feet, provided that:
Gutter flow widths on local and local collector streets shall not exceed 11 feet or such narrower width as may be necessary to provide a twelve-foot-wide clear lane in the center of the roadway.
Gutter flow widths on minor collector streets shall not exceed nine feet or such narrower width as may be necessary to provide two twelve-foot-wide clear lanes in the center of the roadway.
Gutter flow widths on major collector streets without shoulders shall not exceed five feet or such narrower width as may be necessary to provide four ten-foot-wide clear lanes in the center of the roadway.
Gutter flow widths on minor and principal arterial streets and major collector streets with shoulders shall be retained within the shoulder areas.
Swale gutter flow widths in parking areas shall not exceed 12 feet.
Gutter flow widths shall provide for maintenance of two ten-foot-wide clear lanes in all access and major circulation drives and one twelve-foot-wide clear lane in all other aisles in all parking areas.
Maximum design capacities which may be used to determine actual inlet location and spacing are:
Not in sump conditions.
E (in paved areas)
E (in yard areas)
In sump conditions: to be individually designated.
Only Type B inlets shall be used in curbed roadways or curbed access or major circulation drives.
Generally, sufficient inlets will be placed to eliminate any flow exceeding two cubic feet per second across any intersections.
Parking areas may be designed to allow ponding in order to decrease intensity of runoff. In such case, ponding will not be allowed in any access or major circulation drive or in any area of heavy pedestrian activity and shall not exceed six inches at any point calculated for the appropriate design storm in accordance with Subsection G and shall meet the criteria set forth.[1]
Open channels shall be designed to contain the required flow and shall have a design velocity low enough, in the judgment of the Land Use Board Engineer, to prevent erosion. The minimum easement for open channel sections shall be the maximum design top width of the channel section segment plus 25 feet, rounded to the next highest five-foot increment. The excess easement area shall be provided offset to that side of the channel most convenient for use by maintenance crews. The minimum distance between the channel top edge and any easement line shall be five feet. Excess velocity, if any, as determined by the Land Use Board Engineer, in open channels must be controlled by sod, riprap, paving, ditch checks or other suitable methods. Changes of direction in open channels must have a maximum radius of 800 feet or be adequately paved or riprapped.
Generally, unlined open channel cross sections shall have side slopes not steeper than 4:1 for channel depths of two feet or less and not steeper than 8:1 for channel depths of more than two feet. Lined open channel side slopes shall not be steeper than 2:1.
The bottoms of all unlined open channels and the channel side slopes, to at least the design flow level, will be sodded with suitable coarse grass sod.
All unlined open channel side slopes above the design minimum flow level will be topsoiled and seeded or otherwise suitably stabilized in accordance with an approved soil disturbance permit.
All unlined open channels which can be expected to have a base flow of five cubic feet per second or more for at least two out of every 12 months will be provided with a low flow channel using gabions, riprap, lining, 1/3 pipe sections or other arrangements approved as part of the final plat submission.
Minimum basis for calculations. Design storm frequency.
For closed conduits: 25 years; or if the above results in a conduit size at least equivalent to a fifty-four-inch reinforced concrete pipe, then 100 years.
For open channels: 25 years; or if the tributary area exceeds 50 acres, then 100 years. The flooding limits for storms with a return period of twice the design storm shall be determined for all open channels. Such limits shall form the basis of the drainage or conservation easements delineated on the plat.
For detention facilities: a twenty-four-hour flood with a return period not less than 50 years or, if the tributary area exceeds 50 acres, then 100 years.
For retention facilities: twice the one-hundred-year storm for all conditions.
For gutter flow calculations: 10 years for local, local collector and minor collector streets; 25 years for major collectors and minor arterials; 50 years for principal arterials.
Special drainage provisions.
The existing system of natural drainage within each development shall be preserved to the maximum extent possible. To this end, the Board may require the preservation of natural drainage swales, recharge areas, wet weather ponds and similar nonstructural management options as described and regulated in the New Jersey Best Management Practices Manual, latest edition, and may require suitable drainage and conservation easements and possible increases in lot size to allow usable lots with the preservation of such features.
Subject to review and approval by the Board, the design of the development may be modified to take advantage of the natural drainage features of the land. In such review, the Board will use the following criteria:
The utilization of the natural drainage system to the fullest extent possible.
The maintenance of the natural drainage system as much as possible in its unimproved state.
When drainage channels are required, wide shallow swales with natural vegetation will be preferred to other sections.
The construction of flow-retarding devices, detention areas and recharge berms to minimize runoff value increases.
Maintenance of the base flow in streams, reservoirs and ponds.
The reinforcement, improvement and/or extension of the natural drainage system to such an extent as is necessary to eliminate flooding and excess maintenance requirements.
All developments or portions of total schemes of development which, based upon the preliminary plat submission, total 15 or more acres will be expected, to the extent that the Board considers possible, to limit the total stormwater runoff from the site after development to not more than 115% of the runoff from the site in its undeveloped state. The utilization of the provisions of this section to limit such runoff are encouraged. However, the Board may require the use of reasonable artificial methods of detention and/or recharge if it determines that natural provisions are not feasible. The Board may waive the provision of this section if the nature of the development, the character of adjacent previously developed areas or other factors make the utilization of natural drainage features or runoff-limiting devices inadvisable or impractical.
If a structural stormwater management measure has an outlet structure, escape provisions shall be incorporated in or on the structure. Escape provisions means the permanent installation of ladders, steps, rungs or other features that provide readily accessible means of ingress and egress from the outlet structure.
The trash rack should be constructed primarily of bars aligned in the direction of flow 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 bars of the trash rack shall be spaced no greater than 1/3 the width of the hydraulic opening it is protecting or six inches, whichever is less. Transverse bars aligned perpendicular to flow should be sized and spaced as necessary for rack stability and strength.
The trash rack shall be constructed and installed to be rigid, durable and corrosion-resistant, and shall be designed to withstand a perpendicular live loading of 300 pounds per square foot.
The overflow grate shall be constructed and installed to be rigid, durable and corrosion-resistant, and shall be designed to withstand a perpendicular live loading of 300 pounds per square foot.
The maximum side slope for an earthen dam, embankment or berm shall not be steeper than three horizontal to one vertical.
Safety ledges shall be constructed on the slopes of all new structural stormwater management measures 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 foot to 1 1/2 feet above the permanent water surface. See Subsection I(5)(a) below for an illustration of safety ledges in a stormwater management basin.

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 Subsection B(2) and (3) above to Eagleswood Township once per year.
Preventative and corrective maintenance shall be performed to maintain the function of the stormwater management measure, including, but not limited to, repairs or replacement to any associated appurtenance of the measure; removal of sediment, debris or trash; restoration of eroded areas; snow and ice removal; fence repair or replacement; restoration of vegetation; repair or replacement of linings; and restoration of infiltration function.
Stormwater management measure easements shall be provided by the property owner as necessary for facility inspections and maintenance and preservation of stormwater runoff conveyance, infiltration and detention areas and facilities. The purpose of the easement shall be specified in the maintenance agreement.
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, Eagleswood Township 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. Eagleswood Township, 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, Eagleswood Township 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 Eagleswood Township 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.
Once per month (if needed): mow side slopes, remove litter and debris, stabilize eroded banks, and repair erosion at inflow structure;

NJDEP nonstructural strategies point system. The New Jersey Stormwater Management Rules at N.J.A.C. 7:8-5.2(a) and § 295-79A 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 uppermost mineral horizon in a normal soil profile. The upper part of the A-horizon is characterized by maximum accumulation of finely divided, dark-colored organic residues, known as humus, which are intimately mixed with the mineral particles of the soil.
A soil textural class, as shown in Subsection C(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 naturally occurring unit of soil structure consisting of particles of sand, silt, clay, organic matter and coarse fragments held together by the natural cohesion of the soil.
A description of the soil profile, which includes the depth, thickness, color, texture, coarse fragment content, mottling, structure and consistence of each soil horizon or substratum.
A grouping of soil types possessing a specific range of soil profile characteristics which are described within the County Soil Survey Report. Each soil series may consist of several "soil phases," which may differ in slope, texture of the surface horizon or stoniness.
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 Eagleswood Township.
A soil test pit log shall be prepared for each soil test pit. The test pit log shall, at a minimum, provide the elevation of the existing ground surface, the depth and thickness (in inches) of each soil horizon or substratum, the dominant matrix or background and mottle colors using the Munsell system of classification for hue, value and chroma, the appropriate textural class as shown on the USDA textural triangle, the volume percentage of coarse fragments (larger than two millimeters in diameter), the abundance, size and contrast of mottles, the soil structure, soil consistence and soil moisture condition, using standard USDA classification terminology for each of these soil properties. Soil test pit logs shall identify the presence of any soil horizon, substratum or other feature that exhibits an in-place permeability rate less than one inch per hour.
Each soil test pit log shall report the depth to seasonally high-water level, either perched or regional, and the static water level based upon the presence of soil mottles or other redoximorphic features, and observed seepage or saturation. Where redoximorphic features including soil mottles resulting from soil saturation are present, they shall be interpreted to represent the depth to the seasonal high-water table unless soil saturation or seepage is observed at a higher level. When the determination of the seasonally high-water table shall be made in ground previously disturbed by excavation, direct observation of the static water table during the months of January through April shall be the only method permitted.
Stormwater infiltration BMPs shall not be installed in soils that exhibit artesian groundwater conditions. A permeability test shall be conducted in all soils that immediately underlie a perched zone of saturation. Any zone of saturation which is present below a soil horizon which exhibits an in-place permeability of less than 0.2 inches per hour shall be considered an artesian zone of saturation unless a minimum one-foot-thick zone of unsaturated soil, free of mottling or other redoximorphic features, and possessing a chroma of four or higher, exists immediately below the unsuitable soil.
A minimum of one permeability test shall be performed at each soil test pit location. All stormwater basins shall have two test pits and two permeability tests per basin. The soil permeability rate shall be determined using test methodology as prescribed in N.J.A.C. 7:9A-6.2 (tube permeameter test), 7:9A-6.5 (pit bailing test) or 7:9A-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.
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 Eagleswood 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 are 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 § 295-80B(1) of this article.
Bicycle-safe inlet grates. Site development plans that incorporate site design features that help to prevent discharge of trash and debris from drainage systems shall comply with the following standard to control passage of solid and floatable materials through storm drain inlets. For purposes of this paragraph, "solid and floatable materials" means sediment, debris, trash and other floating, suspended or settleable solids.
A different grate, if each individual clear space in that grate has an area of no more than seven square inches or is no greater than 0.5 inch across the smallest dimension. 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 spacer 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 § 295-78 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:
