A.
Scope and purpose.
(1)
Policy statement. 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.
(2)
Purpose. The purpose of this section is to establish minimum stormwater management requirements and controls for "major development," as defined below in Subsection B.
(3)
(4)
Compatibility with other permit and ordinance requirements.
(a)
Development approvals issued pursuant to this section are to
be considered an integral part of development approvals 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 section shall be held to be the minimum requirements
for the promotion of the public health, safety, and general welfare.
(b)
This section 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 section
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.

(7)
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 in accordance with Subsection F(2). Alternative stormwater management measures may be used to satisfy the requirements at Subsection D(15) only if the measures meet the definition of green infrastructure at Subsection B. Alternative stormwater management measures that function in a similar manner to a BMP listed at Subsection D(15)(b) are subject to the contributory drainage area limitation specified at Subsection D(15)(b) 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 at Subsection D(15)(b) 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 Subsection D(4) is granted from Subsection D(15).
(8)
Whenever the stormwater management design includes one or more BMPs
that will infiltrate stormwater into subsoil, the design engineer
shall assess the hydraulic impact on the groundwater table and design
the site, so as to avoid adverse hydraulic impacts. Potential adverse
hydraulic impacts include, but are not limited to, exacerbating a
naturally or seasonally high water table, so as to cause surficial
ponding, flooding of basements, or interference with the proper operation
of subsurface sewage disposal systems or other subsurface structures
within the zone of influence of the groundwater mound, or interference
with the proper functioning of the stormwater management measure itself.
(9)
Design standards for stormwater management measures are as follows:
(a)
Stormwater management measures shall be designed to take into
account the existing site conditions, including, but not limited to,
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);
(b)
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 Subsection H(3);
(c)
Stormwater management measures shall be designed, constructed,
and installed 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, 7.4, and 7.5 shall
be deemed to meet this requirement;
(d)
Stormwater management BMPs shall be designed to meet the minimum safety standards for stormwater management BMPs at Subsection H; and
(e)
The size of the orifice at the intake to the outlet from the
stormwater management BMP shall be a minimum of 2 1/2 inches
in diameter.
(10)
Manufactured treatment devices may be used to meet the requirements of this subchapter, provided the pollutant removal rates are verified by the New Jersey Corporation for Advanced Technology and certified by the Department. Manufactured treatment devices that do not meet the definition of green infrastructure at Subsection B. may be used only under the circumstances described at Subsection D(15)(d).
(11)
Any application for a new agricultural development that meets the definition of major development at Subsection B shall be submitted to the Soil Conservation District for review and approval in accordance with the requirements at Subsection D(15), (16), (17) and (18) and any applicable Soil Conservation District guidelines for stormwater runoff quantity and erosion control. For purposes of this subsection, "agricultural development" means land uses normally associated with the production of food, fiber, and livestock for sale. Such uses do not include the development of land for the processing or sale of food and the manufacture of agriculturally related products.
(12)
If there is more than one drainage area, the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsection D(16), (17) and (18) shall be met in each drainage area, unless the runoff from the drainage areas converge on site and no adverse environmental impact would occur as a result of compliance with any one or more of the individual standards being determined utilizing a weighted average of the results achieved for that individual standard across the affected drainage areas.
(13)
Any stormwater management measure authorized under the municipal stormwater management plan or ordinance shall be reflected in a deed notice recorded in the Office of the Burlington County Clerk. A form of deed notice shall be submitted to the municipality for approval prior to filing. The deed notice shall contain a description of the stormwater management measure(s) used to meet the green infrastructure, groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsection D(15), (16), (17) and (18) and shall identify the location of the stormwater management measure(s) in NAD 1983 State Plane New Jersey FIPS 2900 US Feet or Latitude and Longitude in decimal degrees. The deed notice shall also reference the maintenance plan required to be recorded upon the deed pursuant to Subsection J(2)(e). Prior to the commencement of construction, proof that the above-required deed notice has been filed shall be submitted to the municipality. Proof that the required information has been recorded on the deed shall be in the form of either a copy of the complete recorded document or a receipt from the clerk or other proof of recordation provided by the recording office. However, if the initial proof provided to the municipality is not a copy of the complete recorded document, a copy of the complete recorded document shall be provided to the municipality within 180 calendar days of the authorization granted by the municipality.
(14)
A stormwater management measure approved under the municipal stormwater management plan or ordinance may be altered or replaced with the approval of the municipality, if the municipality determines that the proposed alteration or replacement meets the design and performance standards pursuant to Subsection D of this section and provides the same level of stormwater management as the previously approved stormwater management measure that is being altered or replaced. If an alteration or replacement is approved, a revised deed notice shall be submitted to the municipality for approval and subsequently recorded with the Office of the Burlington County Clerk and shall contain a description and location of the stormwater management measure, as well as reference to the maintenance plan, in accordance with Subsection D(13) above. Prior to the commencement of construction, proof that the above required deed notice has been filed shall be submitted to the municipality in accordance with Subsection D(13) above.
(15)
Green infrastructure standards.
(a)
This subsection specifies the types of green infrastructure
BMPs that may be used to satisfy the groundwater recharge, stormwater
runoff quality, and stormwater runoff quantity standards.
(b)
To satisfy the groundwater recharge and stormwater runoff quality standards at Subsection D(16) and (17), the design engineer shall utilize green infrastructure BMPs identified in Table 1 at Subsection D(6) and/or an alternative stormwater management measure approved in accordance with Subsection D(7). The following green infrastructure BMPs are subject to the following maximum contributory drainage area limitations:
|

(d)
If a variance in accordance with N.J.A.C. 7:8-4.6 or a waiver from strict compliance in accordance with Subsection D(4) is granted from the requirements of this subsection, then BMPs from Table 1, 2, or 3, and/or an alternative stormwater management measure approved in accordance with Subsection D(7) may be used to meet the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsection D(16), (17) and (18).
(e)
For separate or combined storm sewer improvement projects, such as sewer separation, undertaken by a government agency or public utility (for example, a sewerage company), the requirements of this subsection shall only apply to areas owned in fee simple by the government agency or utility, and areas within a right-of-way or easement held or controlled by the government agency or utility; the entity shall not be required to obtain additional property or property rights to fully satisfy the requirements of this subsection. Regardless of the amount of area of a separate or combined storm sewer improvement project subject to the green infrastructure requirements of this subsection, each project shall fully comply with the applicable groundwater recharge, stormwater runoff quality control, and stormwater runoff quantity standards at Subsection D(16), (17) and (18), unless the project is granted a waiver from strict compliance in accordance with Subsection D(4).
(16)
Groundwater recharge standards.
(a)
This subsection contains the minimum design and performance
standards for groundwater recharge as follows.
(b)
The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at Subsection E, either:
[1]
Demonstrate through hydrologic and hydraulic analysis that the
site and its stormwater management measures maintain 100% of the average
annual pre-construction groundwater recharge volume for the site;
or
[2]
Demonstrate through hydrologic and hydraulic analysis that the
increase of stormwater runoff volume from pre-construction to post-construction
for the two-year storm is infiltrated.
(c)
This groundwater recharge requirement does not apply to projects within the "urban redevelopment area," or to projects subject to Subsection D(16)(d) below.
(d)
The following types of stormwater shall not be recharged:
[1]
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 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
[2]
Industrial stormwater exposed to source material. "Source material"
means any material(s) or machinery, located at an industrial facility
that is directly or indirectly related to process, manufacturing or
other industrial activities, which could be a source of pollutants
in any industrial stormwater discharge to groundwater. Source materials
include, but are not limited to, raw materials; intermediate products;
final products; waste materials; by-products; industrial machinery
and fuels, and lubricants, solvents, and detergents that are related
to process, manufacturing, or other industrial activities that are
exposed to stormwater.
(17)
Stormwater runoff quality standards.
(a)
This subsection contains the minimum design and performance
standards to control stormwater runoff quality impacts of major development.
Stormwater runoff quality standards are applicable when the major
development results in an increase of 1/4 acre or more of regulated
motor vehicle surface.
(b)
Stormwater management measures shall be designed to reduce the
post-construction load of total suspended solids (TSS) in stormwater
runoff generated from the water quality design storm as follows:
[1]
Eighty percent TSS removal of the anticipated load, expressed
as an annual average shall be achieved for the stormwater runoff from
the net increase of motor vehicle surface.
[2]
If the surface is considered regulated motor vehicle surface
because the water quality treatment for an area of motor vehicle surface
that is currently receiving water quality treatment either by vegetation
or soil, by an existing stormwater management measure, or by treatment
at a wastewater treatment plant is to be modified or removed, the
project shall maintain or increase the existing TSS removal of the
anticipated load expressed as an annual average.
(c)
The requirement to reduce TSS does not apply to any stormwater runoff in a discharge regulated under a numeric effluent limitation for TSS imposed under the New Jersey Pollutant Discharge Elimination System (NJPDES) rules, N.J.A.C. 7:14A, or in a discharge specifically exempt under a NJPDES permit from this requirement. Every major development, including any that discharge into a combined sewer system, shall comply with Subsection D(17)(b) above, unless the major development is itself subject to a NJPDES permit with a numeric effluent limitation for TSS or the NJPDES permit to which the major development is subject exempts the development from a numeric effluent limitation for TSS.
(d)
The water quality design storm is 1.25 inches of rainfall in
two hours. Water quality calculations shall take into account the
distribution of rain from the water quality design storm, as reflected
in Table 4, below. The calculation of the volume of runoff may take
into account the implementation of stormwater management measures.

If more than one BMP in series is necessary to achieve the required
80% TSS reduction for a site, the applicant shall utilize the following
formula to calculate TSS reduction:
|
R = A + B - (A x B)/100
|
|
Where:
| ||
|
R
|
=
|
total TSS percent load removal from application of both BMPs;
|
|
A
|
=
|
the TSS percent removal rate applicable to the first BMP; and
|
|
B
|
=
|
the TSS percent removal rate applicable to the second BMP.
|
(f)
Stormwater management measures shall also be designed to reduce, to the maximum extent feasible, the post-construction nutrient load of the anticipated 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 green infrastructure BMPs that optimize nutrient removal while still achieving the performance standards in Subsection D(16), (17) and (18).
(g)
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
in stormwater runoff to waters classified as FW1.
(h)
The Flood Hazard Area Control Act Rules at N.J.A.C. 7:13-4.1(c)1
establish 300-foot riparian zones along Category One waters, as designated
in the Surface Water Quality Standards at N.J.A.C. 7:9B, and certain
upstream tributaries to Category One waters. A person shall not undertake
a major development that is located within or discharges into a 300-foot
riparian zone without prior authorization from the Department under
N.J.A.C. 7:13.
(i)
Pursuant to the Flood Hazard Area Control Act Rules at N.J.A.C.
7:13-11.2(j) 3.i, runoff from the water quality design storm that
is discharged within a 300-foot riparian zone shall be treated in
accordance with this subsection to reduce the post-construction load
of total suspended solids by 95% of the anticipated load from the
developed site, expressed as an annual average.
(j)
This stormwater runoff quality standards do not apply to the
construction of one individual single-family dwelling, provided that
it is not part of a larger development or subdivision that has received
preliminary or final site plan approval prior to December 3, 2018,
and that the motor vehicle surfaces are made of permeable material(s)
such as gravel, dirt, and/or shells.
(18)
Stormwater runoff quantity standards.
(a)
This subsection contains the minimum design and performance
standards to control stormwater runoff quantity impacts of major development.
(b)
In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at Subsection E, complete one of the following:
[1]
Demonstrate through hydrologic and hydraulic analysis that for
stormwater leaving the site, post-construction runoff hydrographs
for the two-, ten-, and 100-year storm events do not exceed, at any
point in time, the pre-construction runoff hydrographs for the same
storm events;
[2]
Demonstrate through hydrologic and hydraulic analysis that there
is no increase, as compared to the pre-construction condition, in
the peak runoff rates of stormwater leaving the site for the two-,
ten- and 100-year storm events and that the increased volume or change
in timing of stormwater runoff will not increase flood damage at or
downstream of the site. This analysis shall include the analysis of
impacts of existing land uses and projected land uses assuming full
development under existing zoning and land use ordinances in the drainage
area;
[3]
Design stormwater management measures so that the post-construction
peak runoff rates for the two-, ten- and 100-year storm events are
50%, 75% and 80%, respectively, of the pre-construction peak runoff
rates. The percentages apply only to the post-construction stormwater
runoff that is attributable to the portion of the site on which the
proposed development or project is to be constructed; or
[4]
In tidal flood hazard areas, stormwater runoff quantity analysis in accordance with Subsection D(18)(b)[1], [2] and [3] above is required unless the design engineer demonstrates through hydrologic and hydraulic analysis that 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.
(c)
The stormwater runoff quantity standards shall be applied at
the site's boundary to each abutting lot, roadway, watercourse,
or receiving storm sewer system.
E.
Calculation of stormwater runoff and groundwater recharge:
(1)
Stormwater runoff shall be calculated in accordance with the following:
(a)
The design engineer shall calculate runoff using one of the
following methods:
[1]
The USDA Natural Resources Conservation Service (NRCS) methodology,
including the NRCS Runoff Equation and Dimensionless Unit Hydrograph,
as described in Chapters 7, 9, 10, 15 and 16 Part 630, Hydrology National
Engineering Handbook, incorporated herein by reference as amended
and supplemented. This methodology is additionally described in Technical
Release 55 - Urban Hydrology for Small Watersheds (TR-55), dated June
1986, incorporated herein by reference 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
or at United States Department of Agriculture Natural Resources Conservation
Service, 220 Davison Avenue, Somerset, New Jersey 08873; or
[2]
The Rational Method for peak flow and the Modified Rational
Method for hydrograph computations. The rational and modified rational
methods are described in "Appendix A-9 Modified Rational Method" in
the Standards for Soil Erosion and Sediment Control in New Jersey,
January 2014. This document is available from the State Soil Conservation
Committee or any of the Soil Conservation Districts listed at N.J.A.C.
2:90-1.3(a)3. The location, address, and telephone number for each
Soil Conservation District is available from the State Soil Conservation
Committee, PO Box 330, Trenton, New Jersey 08625. The document is
also available at: http://www.nj.gov/agriculture/divisions/anr/pdf/2014NJSoilErosionControlSta
ndardsComplete.pdf.
(b)
For the purpose of calculating runoff coefficients and groundwater recharge, there is a presumption that the pre-construction 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 above at Subsection E(1)(a)[1] and the Rational and Modified Rational Methods at Subsection E(1)(a)[2]. 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 application. 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 hydrologic condition and conservation treatment (if the land use type is cultivation).
(c)
In computing pre-construction stormwater runoff, the design
engineer shall account for all significant land features and structures,
such as ponds, wetlands, depressions, hedgerows, or culverts that
may reduce pre-construction stormwater runoff rates and volumes.
(d)
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.
(e)
If the invert of the outlet structure of a stormwater management
measure is below the flood hazard design flood elevation as defined
at N.J.A.C. 7:13, the design engineer shall take into account the
effects of tailwater in the design of structural stormwater management
measures.
(2)
Groundwater recharge may be calculated in accordance with the following:
The New Jersey Geological Survey Report GSR-32, A Method for Evaluating
Groundwater-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 the New Jersey Geological Survey website at: https://www.nj.gov/dep/njgs/pricelst/gsreport/gsr32.pdf

grate, which is described in Chapter 2.4 of the NJDOT Bicycle Compatible
Roadways and Bikeways Planning and Design Guidelines; or
[2]
A different grate, if each individual clear space in that grate
has an area of no more than 7.0 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 system floors used to collect stormwater from the surface
into a storm drain or surface water body.
[3]
For curb-opening inlets, including curb-opening inlets in combination
inlets, the clear space in that curb opening, or each individual clear
space if the curb opening has two or more clear spaces, shall have
an area of no more than 7.0 square inches, or be no greater than 2.0
inches across the smallest dimension.
(b)
The standard in Subsection G(1)(a) above does not apply:
[1]
Where each individual clear space in the curb opening in existing
curb-opening inlet does not have an area of more than 9.0 square inches;
[2]
Where the municipality agrees that the standards would cause
inadequate hydraulic performance that could not practicably be overcome
by using additional or larger storm drain inlets;
[3]
Where flows from the water quality design storm as specified
in N.J.A.C. 7:8 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:
[a]
A rectangular space 4 5/8 (4.625) inches long
and 1 1/2 (1.5) inches wide (this option does not apply for outfall
netting facilities); or
[b]

Note that these exemptions do not authorize any infringement
of requirements in the Residential Site Improvement Standards for
bicycle safe grates in new residential development [N.J.A.C. 5:21-4.18(b)2
and 7.4(b)1].
[4]
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 N.J.A.C. 7:8; or
[5]
Where the New Jersey Department of Environmental Protection
determines, pursuant to the New Jersey Register of Historic Places
Rules at N.J.A.C. 7:4-7.2(c), that action to meet this standard is
an undertaking that constitutes an encroachment or will damage or
destroy the New Jersey Register listed historic property.
H.

In residential subdivisions, fire hydrants shall be
located so that the distance from any building frontage to a fire
hydrant is not more than 600 feet, measured along the curb. In commercial
and industrial subdivisions, standards of the pertinent fire insurance
rating association shall apply. Fire hydrants shall be of a type approved
by the Department of Public Works.
B.
Hydrants will be furnished by the developer and will be equipped with a gate valve so that the hydrant can be isolated from the rest of the system. Costs of the required hydrants, valves and piping shall be included in the surety bond or other form of performance guaranty required under § 158-9.

The street and lot layout of a nonresidential subdivision shall be appropriate to the land use for which the subdivision is proposed and shall conform to the proposed land use and standards established in the General Development Plan and Chapter 180, Zoning, and with the principles and standards of this chapter which are appropriate to the planning of all subdivisions. In addition, the subdivider shall comply with the following:
A.
The subdivider shall demonstrate to the satisfaction
of the Planning Board that the proposed street and block pattern will
permit the logical development of neighboring tracts and that provision
has been made for the extension of power, sewer, water and other utilities
into neighboring tracts which can be similarly developed.
B.
Street rights-of-way and cartway width and street
paving shall be adequate to accommodate the type, weight and volume
of traffic which is anticipated, in accordance with Township specifications.
C.
Streets and railroads (where included) shall be arranged
to minimize accident hazards within the site, to avoid traffic conflicts
on adjacent or connecting streets and to assure adequate circulation
through the entire subdivision.
D.
Off-street parking areas shall be paved according
to specifications of the Township and shall be laid out with raised
barriers or painted stalls to facilitate convenient and efficient
use. If intended for night use, off-street parking areas shall be
suitably illuminated.
E.
Off-street space for truck loading and unloading shall
be provided for commercial and industrial uses. Delivery and refuse
trucks should be able to service each use from a location on the lot
and to maneuver without hazard to those using the parking spaces.
Adjacent residential areas shall be protected from potential nuisance
by the proposed nonresidential use by such means as providing extra
depth to lots which back up on residential areas, arrangement of lighting
facilities and by making provision for permanently landscaped buffer
areas along residential district boundary lines.
F.
Streets intended for truck traffic shall not normally
be extended to residential district boundaries or connected to predominately
residential streets.
G.
As part of and as a condition for approval for each
application for all development or site plans, other than applications
for variances, signs, minor site plans and conditional uses, the applicant
shall comply with the residential site improvement standards promulgated
at N.J.A.C. 5:21-7.1 through N.J.A.C. 5:21-7.6, as amended.

H.
Detention facilities shall be required as a condition
of approval where the peak rate or volume of runoff on the property
or adjacent thereto in its post development condition will exceed
the peak rate or volume of runoff in the precondition for storms with
a minimum return period of 100 years.
[Added 1-26-1998 by Ord. No. 1845-98]
I.
Conservation design approach shall be applied to any
major subdivision or major site plan. Conservation design approach
shall be applied to any tract five acres or more in R-1 and R-1-A
Districts, and any tract three acres or more in R-2 Districts.
[Added 9-22-2008 by Ord. No. 22-2008]
(1)
All conservation design subdivisions shall include
documentation of a four-step design process in determining the layout
of proposed conservation area lands, building sites, streets and lot
lines, as described below.
(a)
Step 1: delineation of conservation area lands.
[1]
Conservation area lands (the undeveloped portions of nonresidential subdivisions and site plans) shall include all primary conservation areas and those parts of the remaining buildable lands with the highest resource significance, as described in § 158-17G, Resource conservation and conservation area delineation standards.
[2]
Proposed conservation area lands shall be designated using the existing resources and site analysis map as a base map and complying with Article XXX, Conservation Area Land Use and Design Standards, of the Zoning Ordinance and § 158-17G, Resource conservation and conservation area delineation standards, of the Subdivision Ordinance, dealing with resource conservation and conservation area delineation standards. Primary conservation areas shall be delineated comprising floodplains, wetlands and slopes over 20%.
[3]
In delineating secondary conservation areas,
the applicant shall prioritize natural and cultural resources on the
tract in terms of their highest to least suitabilities for inclusion
in the proposed conservation area, in consultation with the Planning
Board.
(b)
Step 2: location of building sites, accessory
structures and parking lots. Potential building sites shall be tentatively
located, using the proposed conservation area lands as a base map
as well as other relevant data on the existing resources and site
analysis map such as topography and soils. Building sites should generally
be located not closer than 50 feet from primary conservation areas
and 25 feet from secondary conservation areas, taking into consideration
the potential negative impacts of development on such areas as well
as the potential positive benefits of such locations to provide attractive
views and visual settings for buildings.
(c)
Step 3: alignment of streets and trails. Upon designating the building sites, a street plan shall be designed to provide vehicular access, if appropriate, complying with the standards in § 158-17B herein, and bearing a logical relationship to topographic conditions. Impacts of the street plan on proposed conservation area lands shall be minimized, particularly with respect to crossing environmentally sensitive areas such as wetlands. Street connections shall generally be encouraged to minimize the number of new cul-de-sacs to be maintained by the municipality and to facilitate access to and from buildings in different parts of the tract (and adjoining parcels).
(d)
Step 4: drawing in the lot lines. If appropriate
given the proposed development, lot lines are drawn as required to
delineate the boundaries of individual building lots.
(2)
Applicants shall be prepared to submit four separate sketch maps indicating the findings of each step of the design process to the Planning Board during preliminary and final approval as required in § 158-7.3, Sketch plan review by the Planning Board, and § 158-8.1, Four-step design process for tracts five acres or more in the R-1 and R-1-A Districts and tracts 3 acres or more in R-2 Districts.
