The purpose of this article is to ensure that
development and use of property are functional and attractive, are
assets to the Borough, and minimize adverse impacts upon the site
and surrounding neighborhood.
[Amended 9-23-2014 by Ord. No. 2014-17; 5-14-2019 by Ord. No. 2019-05]
Except as preempted by Residential Site Improvement Standards (RSIS), site design standards under Article IX shall be applicable to all site plans, subdivisions and conditional uses. Departure from such standards shall be governed by N.J.S.A. 40:55D-51.
A.
Design of the development shall take into consideration
all existing local and regional plans for the surrounding community.
B.
Development of the site shall be based on an analysis
of the site. To the maximum extent practicable, development shall
be located to preserve the natural features of the site, to avoid
areas of environmental sensitivity, and to minimize negative impacts
and alteration of natural features.
C.
Prior to submitting an application for consideration of a zoning
permit which involves construction of a structure below grade, the
applicant shall complete a test pit to determine the seasonal high
groundwater table on said property within the area of improvement.
Upon determining the seasonal high groundwater table elevation, the
lowest portion of the proposed finished floor shall be set a minimum
of 18 vertical inches higher than the seasonal high groundwater elevation.
The test pit to determine the seasonal high groundwater table elevation
shall be conducted in the presence of a Borough representative to
confirm the elevation of the seasonal high groundwater demarcation.
D.
The following specific areas shall be preserved as
undeveloped open space to the extent consistent with the reasonable
utilization of land, and in accordance with applicable or local regulations:
(1)
Unique and/or fragile areas, including wetlands as
defined in Section 404 (per Federal Water Pollution Control Act Amendments
of 1972, and delineated on wetlands maps prepared by the U.S. Fish
and Wildlife Service, field verified by on-site inspection);
(2)
Significant trees or stands of trees, defined as the
largest known individual trees of each species in the state, large
trees approaching the diameter of the known largest tree, or species
or clumps of trees that are rare to the area or of particular horticultural
or landscape value;
(3)
Lands in the floodplain, as defined by state or local
regulations; and
E.
The development shall be laid out to avoid adversely
affecting groundwater and aquifer recharge; to reduce cut and fill;
to avoid unnecessary impervious cover; to prevent flooding; to provide
adequate access to lots and sites; and to mitigate adverse effects
of shadow, lighting, noise, odor, traffic, drainage, utilities, and
lack of air on neighboring properties.
F.
The developer shall eliminate or provide adequate
safeguards in his plan against hazards that would impair life, health
or property due to flood, fire and disease.
G.
The developer must comply with all technical standards
and specifications stated in this chapter and in any published standards
and specifications addendum or manual which is adopted by resolution
of the Board of Commissioners. The above-stated requirements as well
as those of other bona fide professional or government organizations
whose technical specifications or standards are referred to in this
chapter and/or the addendum or manual adopted by the Borough shall
be considered to have the same effect of law as if they were part
of this chapter. The Borough Engineer shall be the final authority
regarding any interpretation of these standards and specifications
and shall also approve the design and specifications of any items
of construction that a developer is required to or wishes to construct,
if not otherwise covered by this chapter or addenda or manuals.
If the Master Plan or the Official Map provides
for the reservation of designated walkways or public areas within
the proposed development, before approving a subdivision or site plan,
the Planning Board may further require that such streets, ways, basins,
or areas be shown on the plat in locations and sizes suitable to their
intended uses. The Planning Board may reserve the location and extent
of such streets, ways, basins or areas shown on the plat for a period
of one year after the approval of the final plat or for such further
time as may be agreed to by the developer. Unless during such period
or extension thereof the Borough shall have entered into a contract
to purchase or institute condemnation proceeding according to law
for a fee or a lesser interest in the land comprising such streets,
ways, basins or areas, the developer shall not be bound by such reservations
shown on the plat and may proceed to use such land for private use
in accordance with applicable development regulations. The provisions
of this section shall not apply to the street and roads, flood control
basins or public drainageways necessitated by the subdivision or land
development and required for final approval.
A.
Block length. Blocks shall not be less than 290 feet
nor more than 1,300 feet long. Crosswalks up to 10 feet wide may be
required for blocks more than 600 feet long.
B.
Block width. Blocks shall be wide enough for two tiers
of lots.
C.
Through blocks. Double frontage lots are to be avoided
and generally will not be permitted unless the lots are a minimum
of 200 feet deep. However, where rear yards abut connector streets
and the lots are entirely served by a separate local service or neighborhood
feeder street, use of double frontage may be required.
D.
Lot lines. Lot lines shall be at right angles to street
lines or radial thereto wherever practicable.
E.
House numbers. House numbers shall be assigned to
each lot by the Borough Assessor.
G.
Frontage. All lots shall have frontage on a street
conforming with the design standards contained herein, and improved
in accordance with Borough specifications.
H.
Yard orientation. In order to maintain privacy and
the character of existing neighborhoods, lots shall be oriented so
that side yards adjoin other side yards, and rear yards adjoin other
rear yards. In the case of corner lots, the one rear yard of the lot
is allowed to adjoin the side yard of an adjacent lot.
[Added 3-8-1994 by Ord. No. 1692 A]
A.
Residential lots should front on local service or
feeder streets, not on connector streets.
B.
Every lot shall have sufficient access to it for emergency
vehicles as well as for those needing access to the property in its
intended use.
C.
The placement of units in residential developments
shall take into consideration topography, privacy, building height,
orientation, drainage, and aesthetics.
D.
Buildings shall be spaced so that adequate privacy
is provided for units.
E.
Residential developments with three or more units
per building or structure shall provide a centralized and screened
solid waste and recycling management facility.
[Added 7-23-2002 by Ord. No. 1825, effective 9-15-2002]
Commercial and other developments shall be designed
according to the same principles governing the design of residential
developments; namely, buildings shall be located according to topography,
with environmentally sensitive areas avoided to the maximum extent
practicable; factors such as drainage, noise, odor, and surrounding
land uses considered in siting buildings; sufficient access shall
be provided; and adverse impacts buffered.
A.
Road system and parking areas shall be designed to permit the safe, efficient and orderly movement of traffic; to meet, but not to exceed, the needs of the present and future population served; to have a simple and logical pattern; to provide for safe, efficient and orderly and adequate on-site or off-site parking for residents, customers and visitors; to provide safe, efficient and orderly off-street loading and unloading, including the movement of goods and vehicles; to respect natural features and topography; and to present an attractive streetscape per § 135-85.
[Amended 3-8-1994 by Ord. No. 1692 A]
B.
In residential areas, the road system shall be designed
to serve the needs of the neighborhood and to discourage use by through
traffic.
C.
The pedestrian system shall be located as required for safety per § 135-85. Sidewalks shall be placed parallel to the street, with exceptions permitted to preserve natural features or to provide visual interest.
D.
Bikeways and walkways are encouraged as a means to
facilitate circulation among and between buildings and other properties.
A.
Function and materials. Buffering shall provide a
year-round visual screen in order to minimize adverse impacts. It
may consist of fencing, evergreens, berms, rocks, boulders, mounds,
or combinations thereof to achieve the same objectives.
B.
When required. Every development shall provide sufficient
buffering when topographical or other barriers do not provide reasonable
screening and when the Planning Board determines that there is a need
to shield neighboring properties from any adverse external effects
of a development or to shield the development from negative impacts
of adjacent uses such as streets or railroads. In high-density developments,
when building design and siting do not provide privacy, the Planning
Board may require landscaping, fences, or walls to screen dwelling
units for privacy. Buffers shall be measured from side and rear property
lines, excluding driveways.
C.
Amount required.
(1)
Where residential and nonresidential uses abut each
other, a buffer strip of six feet shall be required between such uses.
Such buffer shall be opaque.
(2)
Parking lots, garbage collection and utility areas,
and loading and unloading areas should be screened around their perimeters
by buffer strips, preferably a minimum of five feet wide.
D.
Design. Arrangements of plantings in buffers shall
provide maximum protection to adjacent properties and avoid damage
to existing plant material. Possible arrangements include planting
in parallel, serpentine, or broken rows. If planted berms are used,
the minimum side slope shall be 2:1.
E.
Planting specifications. Plant materials shall be
sufficiently large and planted in such a fashion that a year-round
screen at least eight feet in height shall be produced within three
growing seasons. All plantings shall be installed according to accepted
horticultural standards.
F.
Maintenance. Plantings shall be watered regularly
and in a manner appropriate for the specific plant species through
the first growing season, and dead and dying plants shall be replaced
by the applicant during the next planting season. No buildings, structures,
storage of materials, or parking shall be permitted within the buffer
area; buffer areas shall be maintained and kept free of all debris,
rubbish, weeds and tall grass. Failure to maintain the approved buffer
shall be considered an unapproved change in the site plan and shall
therefore be a violation of this chapter to be enforced under the
penalty sections of this chapter.[1]
[1]
Editor's Note: See Art. XVI of this chapter.
A.
Purpose.
(1)
Landscaping shall be provided as part of site plan
and subdivision design. It shall be conceived in a total pattern throughout
the site, integrating the various elements of site design, preserving
and enhancing the particular identity of the site, and creating a
pleasing site character.
(2)
Landscaping may include plant materials such as trees,
shrubs, ground covers, perennials, and annuals, and other materials
such as rocks, water, sculpture, art, walls, fences, paving materials,
lighting for aesthetics and street furniture.
(3)
Landscaping shall be planned in such a way that the
site requires as little use of potable water as possible to insure
the survival of the plants. Water conservation is a critical purpose
of this section.
B.
Landscape plan. A landscape plan prepared by a certified landscape architect shall be submitted with each site plan and major subdivision application, unless an exception is granted pursuant to § 135-68B of this chapter. The plan shall identify existing and proposed trees, shrubs, and ground covers; existing landscaping to be removed; natural features such as rock outcropping; and other landscaping elements. The plan shall show where they are or will be located and planting and/or construction details. Where existing plantings are to be retained, the application shall include in the plan's proposed methods of protecting them during construction. The landscape plan shall also address landscape maintenance requirements.
C.
Site protection and general planting requirements.
(1)
Topsoil preservation. Topsoil moved during the course
of construction shall be redistributed on all regraded surfaces so
as to provide at least four inches of even cover to all disturbed
areas of the development and shall be stabilized by seeding or planting.
(2)
Removal of debris. All stumps and other tree parts,
litter, brush, weeds, excess or scrap building materials or other
debris shall be removed from the site and disposed of in accordance
with the law. No tree stumps, or portions of tree trunks or limbs
shall be buried anywhere in the development. All dead or dying trees,
standing or fallen, shall be removed from the site. If trees and limbs
are reduced to chips, they may be used as mulch in landscaped areas,
subject to approval by the Borough Engineer.
(3)
Protection of existing plantings. Maximum effort should
be made to save mature trees, including those trees with a diameter
of 10 inches or more. No material or temporary soil deposits shall
be placed within four feet of shrubs or 10 feet of trees designated
on the landscape plan to be retained. Protective barriers shall be
installed around each plant or group of plants that are to remain
on site. Barriers shall not be supported by the plants they are protecting,
but shall be self-supporting. They shall be a minimum of four feet
high and constructed of a durable material that will last until construction
is completed. Snow fences and silt fences are examples of acceptable
barriers.
[Amended 6-24-2008 by Ord. No. 2008-15]
(3.1)
On-site compensatory tree planting.
In the event that it is impractical or would cause undue hardship
in the opinion of the Planning Board or Zoning Board of Adjustment
that an existing tree with a diameter of 10 inches or more be retained,
compensatory planting shall be provided according to the following
schedule and standards:
[Added 6-24-2008 by Ord. No. 2008-15]

(a)
Replacement trees shall be nursery grown and
comply with American Association of Nurserymen standards for nursery
stock and shall be between 2.5 inches and 3.5 inches in caliper.
(b)
Replacement trees may be used anywhere on site, unless prohibited
by law, and shall be planted in accordance with the standards of the
American Association of Nurserymen. However, if one or more of the
following conditions exist, some or all of the replacement trees may
be planted off site:
[Amended 9-23-2014 by Ord. No. 2014-17]
[1]
The site in question cannot physically accommodate
the total replacement amount of trees, and the applicant contributes
an amount equal to the calculated monetary value of nonreplaced trees
to the Tree Escrow Fund; or
[2]
The Shade Tree Commission and applicant agree in
writing that the applicant shall make payment to the Tree Escrow Fund
based upon a fee schedule which shall be set by a resolution of the
Board of Commissioners each year.
(c)
All trees shall be guaranteed for a minimum
of one year from the time of planting by the applicant against death
and disease.
(d)
In the event that it is impractical to install
replacement trees immediately due to planting hazards or species availability,
a bond covering the total cost of the plant material and installation
shall be posted with the Borough.
(e)
In the event it is impractical to provide the required number
of replacement trees on the subject site, fewer, however, larger,
more valuable replacement trees shall be installed on the site, with
an aggregate cost as installed not less than the estimated aggregate
cost of the required number of replacement trees. Alternatively, the
applicant and the Shade Tree Commission may agree in writing that
the applicant make payment to the Tree Escrow Fund to cover the cost
of planting trees elsewhere in the Borough. Each year the Board of
Commissioners shall, by resolution, establish a fee schedule.
[Amended 9-23-2014 by Ord. No. 2014-17]
(4)
Slope plantings. Landscaping of all cuts and fills
and/or terraces shall be sufficient to prevent erosion, and all roadway
slopes steeper than one foot vertically to three feet horizontally
shall be planted with ground cover appropriate for the purpose and
for soil conditions, water availability, and environment.
(5)
Additional landscaping. In residential developments,
besides the screening and street trees required, additional plantings
or landscaping elements may be required throughout the subdivision
where necessary for climate control, privacy, or other reasons in
accordance with the landscape plan approved by the Planning Board.
In nonresidential developments, all areas of the site not occupied
by buildings and required improvements shall be landscaped by the
planting of grass or other ground cover, shrubs, and trees as part
of the landscape plan approved by the Planning Board.
(6)
Planting specification. Deciduous trees shall be at
least 2 1/2 inches caliper at planting and should be balled and burlapped.
Size of evergreens should be four feet tall and shrubs two feet tall
at planting but may be allowed to vary depending on setting and type
of shrub. Only nursery-grown plant materials shall be acceptable,
and trees, shrubs, and ground cover shall be planted according to
accepted horticultural standards. Dead and dying plants shall be replaced
by the developer during the following planting season.
(7)
Plant species. The plant species selected should be
hardy for this portion of New Jersey and appropriate in terms of function
and size. They should be of a type that requires the least amount
of watering for survival to meet the water conservation purposes of
this section.
D.
Shade trees.
(1)
Location. Applicants shall provide shade trees on
both sides of all streets. The trees shall be planted at a minimum
of one tree per each 25 feet of frontage unless otherwise determined
by the Haddonfield Shade Tree Commission. Tree location, landscape
design, and spacing as determined by the Shade Tree Commission shall
be included as part of the landscape plan approved by the Planning
or Zoning Board.
[Amended 7-23-2002 by Ord. No. 1825, effective 9-15-2002]
(2)
Tree type. Tree type may vary depending on overall
effect desired, but as a general rule, all trees on a street shall
be the same kind except to achieve special effects. Selection of tree
types shall be in accordance with the Shade Tree Commission's approved
plan and be approved by the Planning Board.
(3)
Planting specifications. All trees shall have a caliper
of at least 2 1/2 inches and be nursery grown, of substantially uniform
size and shape, and have straight trunks. Trees shall be properly
planted and staked and provision made by the applicant for regular
watering and maintenance until they are established. Dead and dying
trees shall be replaced by the applicant during the next planting
season.
(4)
Applicants are encouraged to consult with the Shade
Tree Commission early in plan development to ensure that shade tree
plans are compatible with Borough goals and requirements.
E.
Paving materials.
(1)
Design and choice of paving materials used in pedestrian
areas shall consider such factors as function, climate, characteristics
of users, availability, cost, maintenance, glare, drainage, noise,
appearance and compatibility with surroundings.
(2)
Acceptable materials shall include, but are not limited
to, concrete, brick, cement pavers, asphalt and stone.
F.
Walls and fences.
(1)
Walls and fences shall be erected where required for
privacy, screening, separation, security, erosion control, or to serve
other necessary and reasonable functions.
(2)
The design and materials used shall be functional
and compatible with existing and proposed site architecture.
(3)
No fence or wall shall be so constructed or installed
as to constitute a hazard to traffic or safety.
G.
Street furniture.
(1)
Street furniture, such as, but not limited to, trash
receptacles, benches, phone booths and newspaper vending boxes (which
may only be located in commercial zones), shall be located and sized
in accordance with function.
(2)
The different street furniture components shall be
compatible in form, material and finish. Design and materials shall
be coordinated with existing and proposed site architecture. Selection
of street furniture shall take into consideration function, durability,
maintenance, and long-term cost.
A.
Streets shall be classified in a hierarchical system
as follows:
(1)
Local service streets: streets providing direct access
to residential structures, and intended primarily to serve only the
properties along them.
(2)
Feeder streets: streets connecting local service streets;
providing access to community facilities and connector streets.
(3)
Connector streets: streets which provide the principal
connections among communities, and to regional highways, and which
provide the principal means of internal traffic movement.
(4)
Cul-de-sac: a street with one end open for vehicular
and pedestrian access and the other end terminating in a vehicular
turnaround.
(5)
Alley: a service road that provides a secondary means
of access to lots.
B.

C.
Right-of-way. The right-of-way shall be measured from
lot line to lot line and shall be sufficiently wide to contain the
cartway, curbs, sidewalks, utilities and shade trees. The street right-of-way
line shall be parallel to the curbline. In zones where buildings are
permitted to abut the right-of-way lines, a diagonal cutoff may be
employed, provided that sidewalk width and corner visibility are unimpaired.
D.
Continuations. New streets shall be laid out to continue
existing streets at no reduction in width, provided that such continuations
are both reasonable and practicable.
E.
Names. Continuations of exiting streets shall be known
by the same name. Names for new streets shall not duplicate or closely
resemble names for existing streets within the Borough and adjoining
municipalities. The Board of Commissioners of the Borough shall have
the final approval authority for all street names.
F.
Adjacent access. Street layout shall make reasonable
provision for access to adjacent undeveloped areas and the applicant
shall improve these access streets to the limits of the development.
No areas lacking access to a street shall be created.
G.
Reserve strips. Reserve strips controlling access
to the development or to adjacent areas are prohibited.
H.
Half streets. Provision of half streets, except to
complete existing half streets, is prohibited.
I.
Highway frontage. If the development abuts a present
or proposed connector street, the Planning Board may require the use
of through lots as described above or the use of a marginal service
street along the edge of the highway but separated from it by a raised
strip at least five feet wide.
J.
Dead-end streets. Dead-end streets are prohibited
unless constructed as culs-de-sac, not exceeding 500 feet in length,
with a turnaround having a minimum radius of 40 feet to the property
line and a cartway radius of 55 feet.
K.
Directional changes. Changes in street direction shall
be made in accordance with Borough specifications and must be approved
by ordinance by the Board of Commissioners.
L.
Curbs. Curbs shall be constructed for the full length
of all streets and shall be designed to provide a barrier-free ramp
at intersections.
M.
Sidewalks.
(1)
Sidewalks shall be required along the full length
of all streets unless the Planning Board grants an exception for low-density
residential areas.
(2)
Sidewalks shall be placed in the right-of-way, parallel
to the street, unless an exception has been permitted to preserve
topographical or natural features or to provide visual interest, or
unless the applicant shows that an alternative pedestrian system provides
safe and convenient circulation. In commercial and in high-density
residential areas, sidewalks may abut the curb.
(3)
Pedestrianway easements up to 10 feet wide may be
required by the Planning Board through the center of blocks more than
600 feet long to provide circulation or access to schools, playgrounds,
shopping or other community facilities.
(4)
Sidewalks shall measure four feet in width; wider
widths may be necessary near pedestrian generators and employment
centers. Where sidewalks abut curbs and cars overhang the sidewalk,
widths shall be five feet. The width of graded areas shall be the
same as for sidewalks. Neither this provision nor any other provision
of this chapter shall be construed to govern the width or composition
of sidewalks or walkways that are situated on single- or two-family
residential properties or are not in the public right-of-way and parallel
and generally adjacent to any street.
[Amended 7-23-2002 by Ord. No. 1825, effective 9-15-2002]
N.
Construction standards for curbs, sidewalks, bikeways,
and streets. All streets shall be built to Borough standards, or in
accordance with the New Jersey Residential Site Improvement Standards
(N.J.A.C. 5:21-1.1 et seq.), as required. Such standards shall be
as published in the Borough Technical Standards and Specifications
Addendum or Manual.[1] The use of private easements to access properties otherwise
inaccessible from a public right-of-way is prohibited in accordance
with N.J.S.A. 40:55D-35.

Editor's Note: See Appendix containing the
technical specifications at the end of this chapter.
A.
General. An adequate number of off-street parking
spaces shall be required in all zones, and in association with every
residential, office, business, institutional or other use of property.
All businesses and commercial properties must provide a suitable location
for loading and unloading of materials or passengers from vehicles.
Such location shall not interfere with the public street and its uses.

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. It is the purpose of this section to establish minimum stormwater
management requirements and controls for all development, with the
exception of additions and renovations to single-family homes that
do not increase existing impervious coverage by more than 20%, which
conform to the Land Development Ordinance of the Borough of Haddonfield.
(3)
Applicability.
(b)
This section shall also be applicable to all projects undertaken
by the Borough of Haddonfield.
(c)
All new homes and commercial buildings requiring a building
permit issued by the Borough of Haddonfield.
(d)
All additions and renovations that increase existing impervious
coverage by more than 20%.
(4)
Compatibility with other permit and ordinance requirements.
(a)
Approvals issued pursuant to this section are to be considered
an integral part of the approvals 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 section
shall be held to be the minimum requirements for the promotion of
the public health, safety, and general welfare. 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.
(b)
Aspects of stormwater management system design and placement
not preempted by this section shall be in accordance with the Residential
Site Improvement Standards at N.J.A.C. 5:21.

is made of permeable material.
(4)
A waiver from strict compliance from the green infrastructure, groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements of Subsection D(15), D(16) and D(17) may be obtained for the enlargement of an existing public roadway or railroad, or the construction or enlargement of a public pedestrian access, provided that the following conditions are met:
(a)
The applicant demonstrates that there is a public need for the
project that cannot be accomplished by any other means;
(d)
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(4)(c) above within the upstream drainage area of the receiving stream, that would provide additional opportunities to mitigate the requirements of Subsection D(15), D(16) and D(17) that were not achievable on-site.
(5)
Tables 1 through 3 below summarize the ability of stormwater best management practices identified and described in the New Jersey Stormwater Best Management Practices Manual to satisfy the green infrastructure, groundwater recharge, stormwater runoff quality and stormwater runoff quantity standards specified in Subsection D(15), D(16) and D(17). 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.

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(2);
(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) and (17) 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) and (17) shall be met in each drainage area, unless the runoff from the drainage areas converge onsite 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 Camden 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) and (17) 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)(d). 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 Camden 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) and (17).
(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) and (17), unless the project is granted a waiver from strict compliance in accordance with Subsection D(4).
(16)
Erosion control, groundwater recharge and runoff quantity standards.
(a)
Erosion control. The minimum design and performance standards
for soil erosion control are as follows:
[1]
The minimum design and performance standards for erosion control
are those established under the Soil Erosion and Sediment Control
Act, N.J.S.A. 4:24-39 et seq. and implementing rules.
[2]
Soil erosion and sediment controls shall be required for all
development. For development not covered under this section, soil
erosion and sediment control shall be at the direction of the Director
of Community Development.
(b)
Groundwater recharge. The minimum design and performance standards
for groundwater recharge for all development are as follows:
[1]
The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at Subsection E, either:
[a]
Demonstrate through hydrologic and hydraulic analysis
that the site and its stormwater management measures maintain 100%
of the average annual preconstruction groundwater recharge volume
for the site; or
[b]
Demonstrate through hydrologic and hydraulic analysis
that the increase of stormwater runoff volume from preconstruction
to postconstruction for the two-year storm is infiltrated.
[2]
This groundwater recharge requirement does not apply to the
following projects:
[a]
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
[b]
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.
[c]
This groundwater recharge requirement does not
apply to projects within the "urban redevelopment area."
[3]
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 and
other subsurface structures in the vicinity or downgradient of the
groundwater recharge area.
[4]
The design of all proposed infiltration measures shall be based
on on-site boring logs or soil pit profiles as witnessed by the Borough
Engineer. The number and location of required soil borings or soil
pits shall be reviewed by the Borough Engineer and should be based
on the suitability and distribution of soils present at the location
of the proposed infiltration measure. The results of all soil borings,
including the location of the boring and all elevation data, shall
be included in a separate soils report or included on the project
plans.
(c)
Runoff quantity standards. 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, postconstruction runoff hydrographs for
the two-, ten-, and 100-year storm events do not exceed, at any point
in time, the preconstruction runoff hydrographs for the same storm
events;
[2]
Demonstrate through hydrologic and hydraulic analysis that there
is no increase, as compared to the preconstruction 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 postconstruction
peak runoff rates for the two-, ten-, and 100-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.
[4]
In tidal flood hazard areas, or as directed by the Director of Community Development, stormwater runoff quantity analysis in accordance with Subsection D(16)(c)[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.
(d)
The stormwater runoff quantity standards shall be applied at
the site's boundary to each abutting lot, roadway, watercourse,
or receiving storm sewer system.
(17)
Stormwater runoff quality standards. 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.
(a)
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.
(b)
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)(a)[2] 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.
(c)
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.

(d)
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 - (AxB)/100
|
|
Where:
| ||
|
R
|
=
|
total TSS percent load removal from application of both BMPs
|
|
A
|
=
|
TSS percent removal rate applicable to the first BMP
|
|
B
|
=
|
TSS percent removal rate applicable to the second BMP
|
(e)
If there is more than one on-site drainage area, the 80% TSS
removal rate shall apply to each drainage area, unless the runoff
from the subareas converge on site, in which case the removal rate
can be demonstrated through a calculation using a weighted average.
(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) and (17).
(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.
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/2014NJSoilErosionControlStandardsComplete.pdf.
(b)
For the purpose of calculating runoff coefficients and groundwater
recharge, there is a presumption that the preconstruction condition
of a site is a wooded land use with good hydrologic condition, unless
otherwise directed by the Borough Engineer. The term "runoff coefficient"
applies to both the NRCS methodology and the rational and modified
rational methods. 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 has 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, unless otherwise directed
by the Borough Engineer. 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 preconstruction 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 preconstruction 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 and 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:
(a)
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 the New Jersey Geological Survey website at:
https://www.nj.gov/dep/njgs/pricelst/gsreport/gsr32.pdf, or at New
Jersey Geological and Water Survey, 29 Arctic Parkway, PO Box 420

G.
Solids and floatable materials control standards.
(1)
Site design features identified under Subsection D(6) above, or alternative designs in accordance with Subsection D(7) above, 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 subsection, "solid and floatable materials" means sediment, debris, trash, and other floating, suspended, or settleable solids. For exemptions to this standard see Subsection G(1)(b) below.
(a)
Design engineers shall use one of the following grates whenever
they use a grate in pavement or another ground surface to collect
stormwater from that surface into a storm drain or surface water body
under that grate:
[1]
The New Jersey Department of Transportation (NJDOT) bicycle
safe 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 seven square inches, or is no greater
than 0.5 inch across the smallest dimension.
[a]
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 seven square inches, or be no greater than
two 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 nine 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 4.625 inches long and 1.5 inches
wide (this option does not apply for outfall netting facilities);
or
[b]
A bar screen having a bar spacing of 0.5 inch.
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.
Safety standards for stormwater management basins.
(1)
This subsection sets forth requirements to protect public safety
through the proper design and operation of stormwater management BMPs.
This subsection applies to any new stormwater management BMP.

Municipal and county stormwater management plans and ordinances may, pursuant to their authority, require existing stormwater management BMPs to be retrofitted to meet one or more of the safety standards in Subsection H(2)(a), (b) and (c) for trash racks, overflow grates, and escape provisions at outlet structures.
(2)
Requirements for trash racks, overflow grates and escape provisions.
(a)
A trash rack is a device designed to catch trash and debris
and prevent the clogging of outlet structures. Trash racks shall be
installed at the intake to the outlet from the stormwater management
BMP to ensure proper functioning of the BMP outlets in accordance
with the following:
[1]
The trash rack shall have parallel bars, with no greater than
six-inch spacing between the bars.
[2]
The trash rack shall be designed so as not to adversely affect
the hydraulic performance of the outlet pipe or structure.
[3]
The average velocity of flow through a clean trash rack is not
to exceed 2.5 feet per second under the full range of stage and discharge.
Velocity is to be computed on the basis of the net area of opening
through the rack.
[4]
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.
(b)
An overflow grate is designed to prevent obstruction of the
overflow structure. If an outlet structure has an overflow grate,
such grate shall meet the following requirements:
[1]
The overflow grate shall be secured to the outlet structure
but be removable for emergencies and maintenance.
[2]
The overflow grate spacing shall be no less than two inches
across the smallest dimension.

(c)
For purposes of this subsection, "escape provisions" means the
permanent installation of ladders, steps, rungs, or other features
that provide easily accessible means of egress from stormwater management
BMP. Stormwater management BMP shall include escape provisions as
follows:
[1]
If a stormwater management BMP has an outlet structure, escape provisions shall be incorporated in or on the structure. Escape provisions include the installation of permanent ladders, steps, rungs, or other features that provide easily accessible means of egress from stormwater management BMPs. With the prior approval of the municipality pursuant to Subsection H(3), a free-standing outlet structure may be exempted from this requirement;
[2]
Safety ledges shall be constructed on the slopes of all new stormwater management BMP 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 H(4) for an illustration of safety ledges in a stormwater management BMP; and
[3]
In new stormwater management BMP, the maximum interior slope
for an earthen dam, embankment, or berm shall not be steeper than
three horizontal to one vertical.
(3)

development project shall be reviewed as a part of the subdivision
application, site plan review process, or zoning permit application
by the municipal board or official from which municipal approval is
sought. That municipal board or official shall consult the engineer
retained by the Borough, the Planning Board and/or Zoning Board (as
appropriate) to determine if all of the checklist requirements have
been satisfied and to determine if the project meets the standards
set forth in this section.
(2.1)
An applicant for approval of a stormwater development
plan for a single- family house or duplex house not part of a major
residential development (regulated by Residential Site Improvement
Standards) is not required to submit a stormwater development plan
for approval to the Haddonfield Planning Board (HPB) or the Haddonfield
Zoning Board (HZB).
(3)
Checklist requirements.
(a)
The following information shall be required:
[1]
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 feet 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 One 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.
[2]
Environmental site analysis. A written and graphic description
of the natural and man-made features of the site and its environs.
This description should include a discussion of soil conditions, slopes,
wetlands, waterways and vegetation on the site. Particular attention
should be given to unique, unusual, or environmentally sensitive features
and to those that provide particular opportunities or constraints
for development.
[3]
Project description and site plan(s). A map (or maps) at the
scale of the topographical base map indicating the location of existing
and proposed buildings, roads, parking areas, utilities, structural
facilities for stormwater management and sediment control, and other
permanent structures. The map(s) shall also clearly show areas where
alterations occur in the natural terrain and cover, including lawns
and other landscaping, and seasonal high groundwater elevations. A
written description of the site plan and justification of proposed
changes in natural conditions may also be provided.
[4]
Land use planning and source control plan. This plan shall provide a demonstration of how the goals and standards of Subsections D, E and F are being met. The focus of this plan shall be to describe how the site is being developed to meet the objective of controlling groundwater recharge, stormwater quality and stormwater quantity problems at the source by land management and source controls whenever possible.
[5]
Stormwater management facilities map. The following information,
illustrated on a map of the same scale as the topographic base map,
shall be included:
[a]
Total area to be paved or built upon, proposed
surface contours, land area to be occupied by the stormwater management
facilities and the type of vegetation thereon, and details of the
proposed plan to control and dispose of stormwater.
[b]
Details of all stormwater management facility designs,
during and after construction, including discharge provisions, discharge
capacity for each outlet at different levels of detention and emergency
spillway provisions with maximum discharge capacity of each spillway.
[6]
Calculations.
[a]
Comprehensive hydrologic and hydraulic design calculations for the predevelopment and post development conditions for the design storms specified in Subsection D of this section.
[b]
When the proposed stormwater management control
measures (e.g., infiltration basins) depend on the hydrologic properties
of soils or require certain separation from the seasonal high-water
table, then a soils report shall be submitted. The soils report shall
be based on on-site boring logs, soil pit profiles, test pits and
in situ infiltration testing using double ring infiltrometer, or approved
equal, witnessed by the Borough Engineer's office. The number
and location of required sol boring or soil pits shall be determined
based on what in needed to determine the suitability and distribution
of soils present at the location of the control measure.
(b)
Waiver from submission requirements. The municipal official or board reviewing an application under this section may, in consultation with the Borough Engineer, waive submission of any of the requirements in Subsection I(3) of this section when it can be demonstrated that the information requested is impossible to obtain or it would create a hardship on the applicant to obtain and its absence will not materially affect the review process.
J.
Maintenance and repair.
(1)
Applicability. This requirement, unless otherwise directed by the
Director of Community Development, shall apply to all major development
and any development that includes the installation of a stormwater
maintenance system, including single-family homes that have been directed
to install a stormwater maintenance system by the Director of Community
Development.
(2)
General maintenance.
(a)
The applicant's/developer's design engineer shall
prepare a maintenance plan for the stormwater management measures
incorporated into the design of a development.
(b)
The maintenance plan shall contain specific preventative maintenance
tasks and schedules; cost estimates, including estimated cost of sediment,
debris, or trash removal; and the name, address, and telephone number
of the person or persons responsible for preventative and corrective
maintenance (including replacement). The plan shall contain information
on BMP location, design, ownership, maintenance tasks and frequencies,
and other details as specified in Chapter 8 of the NJ BMP Manual,
as well as the tasks specific to the type of BMP, as described in
the applicable chapter containing design specifics. A sample maintenance
plan is included at the end of this section. Additional maintenance
guidelines for stormwater management measures are available in the
New Jersey Stormwater Best Management Practices Manual. If the maintenance
plan identifies a person other than the developer (for example, a
public agency or homeowners' association) as having the responsibility
for maintenance, the plan shall include documentation of such person's
agreement to assume this responsibility or of the developer's
obligation to dedicate a stormwater management facility to such person
under an applicable ordinance or regulation.
(c)
Responsibility for maintenance shall not be assigned or transferred
to the owner or tenant of an individual property in a residential
development or project, unless such owner or tenant owns or leases
the entire residential development or project. The individual property
owner may be assigned incidental tasks, such as weeding of a green
infrastructure BMP, provided the individual agrees to assume these
tasks; however, the individual cannot be legally responsible for all
of the maintenance required. A two-year maintenance guarantee in accordance
with N.J.S.A. 40:55D-53 shall be provided at the direction of the
Director of Community Development.
(d)
If the person responsible for maintenance is not a public agency,
the maintenance plan and any future revisions shall be recorded upon
the deed of record for each property on which the maintenance described
in the maintenance plan must be undertaken. A copy of the revised
filed deed shall be provided to the Director of Community Development.
(e)
Preventative and corrective maintenance shall be performed to
maintain the functional parameters (storage volume, infiltration rates,
inflow/outflow capacity, etc.), of the stormwater management measure,
including, but not limited to, repairs or replacement to the structure;
removal of sediment, debris, or trash; restoration of eroded areas;
snow and ice removal; fence repair or replacement; restoration of
vegetation; and repair or replacement of non-vegetated linings.
(g)
The person responsible for maintenance shall evaluate the effectiveness
of the maintenance plan at least once per year and adjust the plan
and the deed as needed.
(h)
The person responsible for maintenance shall maintain a detailed
log of all preventative and corrective maintenance for the structural
stormwater management measures incorporated into the design of the
development, including a record of all inspections and copies of all
maintenance-related work orders.
[1]
The person responsible for maintenance shall provide to the
Director of Community Development on a biennial basis a certification
which states that all maintenance has been conducted per the system
maintenance plan and that the system is operating as designed or within
acceptable tolerances as described within the design report and/or
maintenance plan. This biennial report shall be due by March 1 of
the required year. The first report shall be due two years after the
system has passed installation inspection.
(j)
In the event that the stormwater management facility becomes
a danger to public safety or public health, or if it is in need of
maintenance or repair, the municipality 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 his designee.
The municipality, in 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, the
municipality or county may immediately proceed to do so and shall
bill the cost thereof to the responsible person.
(3)
Nothing in this subsection shall preclude the municipality in which
the development is located from requiring the posting of a performance
or maintenance guarantee in accordance with N.J.S.A. 40:55D-53.
Where development is traversed by a watercourse,
drainageway channel or stream, or where it is desirable to preserve
other areas within the property because of soil conditions, rock outcropping,
tree masses, wildlife habitat, vistas or other significant horticultural,
environmental or natural features, there shall be provided a drainage
and/or conservation easement of sufficient area and width to protect
and preserve the aforementioned features. The extent of such easements
shall be determined by the Environmental Commission and the easements
shall be deeded to the Borough prior to final subdivision approval
and carry the following limitations:
A.
No trees or shrubs shall be removed or disturbed on
lands in the easement except in accordance with approved land management
practice; and
B.
No topsoil, sand, gravel or minerals shall be excavated
or removed, except as may be required to build a pond, and then only
if the Borough approves the design and structure of the pond, it being
the intent to preserve the natural function of the floodplain; and
C.
No buildings of any description shall be erected;
and
D.
No fill of any kind shall be permitted, except as
may be required to build a road, and then only after the Borough approves
the design.
[Added 7-10-2007 by Ord. No. 2007-20]
A.
Statement of purpose.
(1)
It is the express purpose of this section to
provide special qualitative and quantitative development controls
for all lands located within the Borough that have present within
their boundaries topographical conditions, hereinafter defined as
"steep slopes."
(2)
These special development controls are provided
in recognition of the potentially negative impacts of construction
in steep slope areas in the form of erosion, siltation, excessive
removal of vegetation and soil, flooding, soil slippage, water runoff
and destruction of unique land forms and scenic vistas. It is further
the purpose of this section to encourage good land use planning and
design, maximize optimal use of the natural terrain and maintain ridgelines
and scenic vistas intact.
(3)
Effective and reasonable application of these
regulations will protect the health, safety and welfare of the citizens
of the Borough, as well as limit the adverse impact on adjoining and/or
downstream properties.
(4)
This chapter is further promulgated to provide
a functional land use design and control mechanism that will augment
the basic land use controls of this chapter and the administrative
implementation devices contained within the Land Development Ordinance.
B.
Applicability. The requirements, guidelines and controls
promulgated under this chapter shall be applicable to all properties
within all zone districts situated in the Borough in their existing
physical state or condition as of the date of the passage of this
chapter.
C.
Definition. A steep slope is defined as an area of
land where the slope exceeds 15%. Determination of slope shall be
by measurement of run perpendicular to the contours from the top of
the slope to the bottom of the slope for a minimum horizontal interval
of 100 feet.
D.
Permitted uses.
(1)
For slopes less than 15%, all activities are permitted; however, they will be subject to approval of an individual lot grading plan in accordance with § 135-93.1E of this chapter.
(2)
Public parks and outdoor recreation uses shall
be permitted as long as all applicable requirements of the Camden
County Soil Conservation Service are implemented and maintained as
necessary.
(3)
Any public or private soil stabilization or
soil erosion project that has been reviewed and approved by the Borough
Engineer and all other local, state and federal agencies.
(4)
Home gardening and landscaping uses when conducted
in conformance with conservation practices that ensure sufficient
protection against soil erosion.
(5)
Buildings and other structures may be constructed
in accordance with the requirements of this section; however, in no
case shall a new building and/or structure be constructed within 25
feet of a slope greater than 30%. This provision shall not apply in
the event any existing building or structure that is located within
25 feet of a slope greater than 30% is damaged or destroyed in whole
or part by fire, casualty or other force majeure.

No. 2019-13[1]]
A.
For all lots with proposed disturbances, an individual lot grading
plan shall be approved by the Borough Engineer prior to the issuance
of a building permit. All lot grading plans shall be prepared by an
appropriate professional and shall include, but not be limited to,
the following:
(1)
Existing and proposed contours on the property and within 25
feet of all property lines.
(2)
Limit of soil disturbance.
(3)
Appropriate construction details.
(4)
Soil erosion, sedimentation control measures and drainage calculations.
(5)
Where required by the Community Development Director, existing
and proposed stormwater control measures.
B.
The design standards for lot grading plans shall be pursuant to the
following standards:
(1)
No soil shall be excavated, removed, deposited or disturbed
except as a result of and in accordance with a lot grading plan approved
under the terms of this chapter.
(2)
Proposed disturbance of soil shall be minimized, for purposes
consistent with the intent of this chapter, and it shall be executed
in a manner that will not cause erosion or other unstable conditions.
(3)
The grading plan requirements are for the purpose of confirming
that proposed applicable developments will not result in flooding,
pooling or other drainage-related problems at the lot on which the
development is proposed or on adjacent properties. Each grading plan
must therefore confirm, to the Borough Engineer's satisfaction,
that the proposed applicable development on each lot will cause water
to drain properly from the lot on which such development is proposed,
and that such development will not increase the amount of water which
drains onto adjoining lots (except as otherwise permitted as part
of a final site plan, subdivision, or other Planning Board or Borough
approval) or adversely change the manner in which it drains.
[Amended 3-9-2021 by Ord. No. 2021-03]
(4)
Provision shall be made for any structure or protective measures
that proposed slopes may require for the protection of the public
safety, including but not limited to retaining walls, guide rails,
headwalls and fences.
(5)
Any proposed building or structure or attendant protective measures
will not impede the flow of surface water through any watercourse.
Only a nominal increase in water surface elevation and velocities
will be allowed due to construction.
(6)
Any proposed vehicular facilities, including roads, drives or
parking areas, shall be so designed that any land disturbances shall
not cause excessive erosion. Both the vertical and horizontal alignment
of vehicular facilities shall be so designed that hazardous circulation
conditions will not be created.
(7)
Final grades of the proposed driveway shall not exceed 10% without
approval by the Borough Engineer.
(8)
Any fill placed on the lot shall be properly stabilized and,
when found necessary depending upon existing slopes and soil types,
supported by retaining walls or other appropriate structures as approved
by the Borough Engineer.
(9)
All cuts shall be supported by retaining walls or other appropriate
retaining structures when, depending upon the nature of the soil characteristics,
such structures are found necessary by the Borough Engineer in order
to prevent erosion.
(10)
There shall be no alternation of site elevations within five
feet of an adjoining property without approval of the Community Development
Director.
(11)
Changes in grade shall not exceed a slope of three to one unless
supported by retaining walls.
(12)
No retaining wall on a residential site shall exceed four feet
in height, and there shall be at least 10 feet between stepped retaining
walls. All retaining walls greater than four feet in height require
a certification by a professional engineer that the wall was constructed
in accordance with approved plans.
C.
For all lot grading plans submitted to and approved by the Borough
Engineer, an as-built plan shall also be submitted for final review
and approval by the Borough Engineer or Community Development Director.
D.
The fee for submission of the grading plan shall be $50. The escrow
amount for review and inspection of the grading plan shall be $1,500.

Editor's Note: This ordinance also provided for the redesignation
of former § 135-92.2 as § 135-92.3.
[Added 5-9-2017 by Ord.
No. 2017-06; amended 5-14-2019 by Ord. No. 2019-05]
No grading shall be undertaken within five feet of adjoining
property lines unless said grading materially improves stormwater
management or is necessary to alleviate a potential safety problem.
Grading for driveways that otherwise meet the requirements of § 135-26B(6)
may be located within five feet of adjoining property lines if the
off-site stormwater impact does not increase as a result of the grading.
[Added 6-25-2019 by Ord.
No. 2019-13]
As part of any approval for a construction permit or a bulk
variance for development of any new construction or expansion of any
existing dwelling or structure, an applicant shall submit to the Construction
Official an as-built survey of the property prepared by a New Jersey
licensed engineer, showing setbacks for all structures to property
lines and the overall height of all buildings on the lot. The as-built
survey shall be submitted and approved prior to the issuance of any
certificate of occupancy for new construction or expansion of existing
structures.
