Egg Harbor Township
Ordinance No. 14
2021
An ordinance to amend Chapter 94 of the Code of the Township of Egg Harbor entitled “Design, Performance and Improvement Standards”, specifically Article IV entitled “Standards”
BE IT ORDAINED, by the Township Committee of the Township of Egg Harbor, in the County of Atlantic, New Jersey as follows:
SECTION 1.
Chapter 94 of the Code of the Township of Egg Harbor, specifically Section 94-44.A (1)(a) is hereby amended by adding the following:
§94-44.
Scope and purpose.
[9] Flood control, groundwater recharge, and pollutant reduction shall be achieved through the use of stormwater management measures, including green infrastructure Best
Management Practices (GI BMPs) and nonstructural stormwater management strategies. GI BMPs and low impact development (LID) should be utilized to meet the goal
of maintaining natural hydrology to reduce stormwater runoff volume, reduce erosion, encourage infiltration and groundwater recharge, and reduce pollution. GI BMPs and
LID should be developed based upon physical site conditions and the origin, nature and the anticipated quantity, or amount, of potential pollutants. Multiple stormwater
management BMPs may be necessary to achieve the established performance standards for water quality, quantity, and groundwater recharge.
SECTION 2.
Chapter 94 of the Township Code of the Township of Egg Harbor, specifically Section 94-44.A (1)(b) is hereby amended by deleting it in its entirety and replacing it with the
following:
(b) Therefore, it is the purpose of this section 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 Egg Harbor Township and to to establish minimum stormwater management requirements and controls for “major development,” as defined below.
SECTION 3.
Chapter 94 of the Code of the Township of Egg Harbor, specifically Section 94-44.A (3)(a) is hereby amended by deleting it in its entirety and replacing it with the following:
(a) All non-residential and residential major developments occurring within Egg Harbor Township that require preliminary or final site plan or subdivision review; and
SECTION 4.
Chapter 94 of the Code of the Township of Egg Harbor, specifically Section 94-44.B (3) is hereby amended by deleting it in its entirety and replacing it with the following:
(3) Checklist requirements.Any application for approval of a major development shall include at least the following information.All required engineering plans shall be submitted to
Egg Harbor Township in AutoCAD 2000 or higher on a USB/Flash drive,, registered and rectified to NJ State Plane Feet NAD 83 or Shape Format NJ State Plan Feet NAD 83, and all
other documents shall be submitted in both paper and commonly used electronic file formats such as pdf, word processing, database or spreadsheet files.Three copies of each
item shall be submitted.
SECTION 5.
Chapter 94 of the Code, specifically Section 94-44.C (2) (a) is hereby amended by deleting it in its entirety and replacing it with the following:
(a) In complying with the stormwater runoff quality standards in § 94-44D (4) (a), the design engineer shall calculate the stormwater runoff rate and volume using the USDA
Natural Resources Conservation Service (NRCS) Runoff Equation, Runoff Curve Numbers, and Dimensionless Unit Hydrograph, as described in the NRCS National Engineering
Handbook Part 630 - Hydrology and Technical Release 55 - Urban Hydrology for Small Watersheds, as amended and supplemented. Information regarding the methodology is
available from the Natural Resources Conservation Service website at: https://www.nrcs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb1044171.pdf
SECTION 6.
Chapter 94 of the Code, specifically Section 94-44.D (2) (a) is hereby amended by deleting it in its entirety and replacing it with the following:
(2) Stormwater runoff quantity and rate standards.
(a) There shall be no direct discharge of stormwater runoff from any point or nonpoint source to any wetland, wetlands transition area or surface water body. In addition, stormwater
runoff shall not be directed in such a way as to increase the volume and/or rate of discharge into any surface water body from that which existed prior to development of the
site. In computing stormwater runoff from all design storms, 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 or other methods may be employed.
SECTION 7.
Chapter 94 of the Code, specifically Section 94-44.D (2) (e) is hereby amended by deleting it in its entirety and replacing it with the following:
(e) In tidal flood hazard areas, a stormwater runoff quantity analysis in accordance with Subsection D (2) (d) [1], [2] and [3] above shall only be applied if the increased volume,
change in timing, or increased rate of the stormwater runoff, or any combination of the three will not result in additional flood damage below the point of discharge of the major
development. No analysis is required if the stormwater is discharged directly into any ocean, bay, inlet, or the reach of any watercourse between its confluence with an ocean,
bay, or inlet and downstream of the first water control structure.
SECTION 8.
Chapter 94 of the Code, specifically Section 94-44.D is hereby amended by adding the following:
D. Stormwater management performance standards for major development.
(9) Green Infrastructure Requirements:
(a) When designed in accordance with the most current version of the New Jersey Stormwater Best Management Practices Manual, the stormwater management measures found
at N.J.A.C. 7:8-5.2 (f) Tables 5-1, 5-2 and 5-3 and listed below in Tables 1, 2 and 3 are presumed to be capable of providing stormwater controls for the design and performance
standards as outlined in the tables below. Upon amendments of the New Jersey Stormwater Best Management Practices to reflect additions or deletions of BMPs meeting these
standards, or changes in the presumed performance of BMPs designed in accordance with the New Jersey Stormwater BMP Manual, the Department shall publish in the New
Jersey Registers a notice of administrative change revising the applicable table. The most current version of the BMP Manual can be found on the Department’s website at:
https://njstormwater.org/bmp_manual2.htm.
(b) An alternative stormwater management measure, alternative removal rate, and/or alternative method to calculate the removal rate may be used if the design engineer
demonstrates the capability of the proposed alternative stormwater management measure and/or the validity of the alternative rate or method to the municipality. A copy of any
approved alternative stormwater management measure, alternative removal rate, and/or alternative method to calculate the removal rate shall be provided to the Department.
Alternative stormwater management measures may be used to satisfy the requirements only if the measures meet the definition of green infrastructure. Alternative stormwater
management measures that function in a similar manner to a BMP are subject to the contributory drainage area limitation for that similarly functioning BMP. Alternative
stormwater management measures approved in accordance with this subsection that do not function in a similar manner to any BMP listed shall have a contributory drainage
area less than or equal to 2.5 acres, except for alternative stormwater management measures that function similarly to cisterns, grass swales, green roofs, standard constructed
wetlands, vegetative filter strips, and wet ponds, which are not subject to a contributory drainage area limitation. Alternative measures that function similarly to standard
constructed wetlands or wet ponds shall not be used for compliance with the stormwater runoff quality standard unless a variance in accordance with N.J.A.C. 7:8-4.6 or a
waiver from strict compliance in accordance with § 94-44D(8).
[1] Where the BMP tables in the NJ Stormwater Management Rule are different due to updates or amendments with the tables in this article the BMP Tables in the stormwater
Management rule at N.J.A.C. 7:8-5.2(f) shall take precedence.
