A.
Clearing. For the full width required for cartways
and drainage swales, the ground surface shall be cleared of trees,
brush, roots, debris and other unsuitable matter before construction
work is commenced. Materials accumulated by clearing, grubbing and
cleaning up, as above-described, shall be disposed of at locations
outside of the limits of the street.
B.
Fill. Materials used for fill shall be suitable therefor
and shall be free from stumps, wood, brush, roots, sod, rubbish, garbage
and other matter that may decay. The fill shall be formed in successive
layers not more than 12 inches deep, and each layer shall be compacted
by operating the construction equipment over it until it is firm and
unyielding before the next layer is placed.
C.
Gravel. The roadway shall be constructed of gravel
to a width of two feet beyond the edge of the paved surface. The gravel
base shall be of a compacted depth of six inches. The gravel shall
be hard, durable pebbles mixed with sand and clay so that the material
can be compacted into a hard, dense mass. It shall conform to the
requirements of the New Jersey State Department of Transportation
Standard Specifications Division 3, Section 1. The subbase shall be
in a properly finished condition and not wet or frozen when the gravel
course is about to be placed thereon. The construction of the gravel
course shall start at the point nearest the source supply, and the
construction trucks shall be operated over the newly placed gravel
in a manner that will tend to give uniform compaction over the entire
width of the pavement. The gravel shall be spread on the full width
of the roadway and edge in a uniform layer of the proper depth. After
being spread, the gravel shall be scraped, and the scraping shall
continue at intervals as the gravel is being consolidated by the construction
equipment, until it is thoroughly compacted. The finished pavement
shall be thoroughly compacted and bound together, hard, smooth and
even, free from defects and at the proper grade and contour.
D.
Bituminous concrete pavement.
(1)
The minimum acceptable standard for street pavement
shall be a two-inch bituminous concrete, type FABC surface on two-inch
bituminous stabilized base on a six-inch gravel or four-inch quarry
blend (type 5, Class A) subbase. The materials used and the method
of construction shall conform to the requirements therefor specified
in the New Jersey State Highway Department Standard Specifications,
Division 3, Section 10, as amended by Addenda A, dated "Revised June
1972."
[Amended 2-19-1980 by Ord. No. 608]
(2)
Materials may be amended to permit the use of three-eighths-inch
washed pebbles as a coarse aggregate if, at the time of construction,
the Township Engineer deems it to be in the best interests of Galloway
Township.
[Amended 2-19-1980 by Ord. No. 608]
(3)
The contractor shall properly prepare the subgrade
for the full width of the pavement and it shall conform to the crown
as shown on the cross section and as directed by the engineer. No
bituminous concrete pavement shall be laid until the existing subbase
has been prepared and thoroughly compacted by the use of an approved
roller.
(4)
Care shall be used to avoid damage to manholes, curbs,
gutters and other existing structures or improvements in the roadways.
E.
Deviation from minimum standards.
[Added 5-21-1979 by Ord. No. 584]
(1)
A temporary deviation from the minimum construction
requirements for a street as hereinabove set forth so as to permit
the temporary construction of a gravel street as may be permitted
by the municipality as is hereinafter set forth.
(2)
The owner of not more than three building lots immediately contiguous to a proposed street, provided that at least one of the said lots is not immediately contiguous to an existing street, may apply to the Code Enforcement Officer for a permit to construct a gravel road as is otherwise provided for in this chapter. The applicant shall advise the Code Enforcement Officer of the location and the length of the street proposed, shall supply the Code Enforcement Officer with a list of each owner of record of any land contiguous to the proposed street in the block in question (either side of the street) and shall advise the Code Enforcement Officer of the projected date for the completion of the street, not to exceed six years from date of the issuance of the building permit, in accordance with the minimum requirements set forth in Subsection D above.
(3)
The Code Enforcement Officer shall present the necessary
information to the Municipal Engineer who will then, as soon as practicable,
supply the Code Enforcement Officer with a written estimate for the
cost of the construction of the street in accordance with the requirements
of the applicable sections of the Comprehensive Land Management Code,
as of the projected date for the completion of said street.
(4)
Upon receipt of said information from the Municipal
Engineer, the Code Enforcement Officer shall supply said information
to the applicant.
(5)
Thereafter, the municipality may enter into a written
agreement with the applicant and any or all of the other landowners
referred to above, who so desire, for the purpose of establishing
an interest-bearing escrow account for the collection of the required
sum of money by the Township necessary to construct the street, as
of the stipulated future date, said sums of money to be collected
from those who agree thereto either as an added assessment to be included
on the landowners' respective tax bills or as may otherwise be agreed
upon by and between the parties. It shall be the responsibility of
the applicant and/or of the other landowners who agree thereto to
pay for the projected costs, in their entirety, of said street. The
municipality shall not be responsible nor shall it be obligated to
collect from any landowner who either voluntarily agrees to said plan
nor from any landowner who fails to agree to said plan. Nothing contained
herein shall operate to preclude any participating landowner or landowners
from pursuing any legal action deemed necessary to protect their individual
interests in this regard.
(6)
Provided that the agreement shall be adhered to, upon
the collection of the full amount as of the projected date of construction,
the Township shall then be obligated, not later than its next succeeding
annual road repair and construction program, to see to the construction
of the street as provided for in accordance with the Comprehensive
Land Management Code for the Township of Galloway.
(7)
In any event, the obligation of the maintenance of
the roadway shall remain solely and exclusively upon the adjacent
and abutting landowners until such time as the street has been constructed
in accordance with the minimum requirements of the Comprehensive Land
Management Code for the Township of Galloway as the same now provides
or as it may hereinafter be amended. Said obligation to maintain the
below-standard roadway in question shall include but shall not be
limited to snow removal, provision for any drainage problems which
may arise and any other aspect of road maintenance which may occur
with respect to said road. The maintenance obligation shall not shift
to the municipality until the same is constructed on behalf of and
accepted by the Township of Galloway in accordance with the procedures
established by the ordinances of the Township of Galloway and the
statutes of the State of New Jersey.
(8)
If, for any reason whatsoever, any one or all of the parties shall miss a payment due [as referred to in Subsection E(5) above], the remaining parties shall become obligated, jointly and severally, to make up and maintain the payment schedule agreed to. The municipality shall have the option to redistribute the cost to the remaining landowners and to collect the same in the manner agreed to by agreement or to put stop notices on ongoing construction and/or to refuse to issue additional building permits on said street as it shall deem in the best interests of the municipality.
(9)
No property owner who owns property on any abutting street constructed or to be constructed under the terms and conditions provided for the construction of streets pursuant to § 233-44 shall be entitled to a building permit for any of said abutting real estate, unless and until the owner in question shall have become a party to the original agreement entered into by the Township of Galloway with any of the other property owners owning real estate on the street in question, under the same terms and conditions of the said agreement and provided further that the said property owner shall have made himself current with respect to the financial deposits required under the agreement in question.
[Added 6-4-1979 by Ord. No. 592]
(10)
Application by one property owner.
[Added 9-2-1980 by Ord. No. 636]
(a)
Any other provision of Subsection E to the contrary notwithstanding, in the event that only one owner of a lot immediately contiguous to a proposed street applies for a building permit together with a permit to construct a gravel road and requests the Township to construct a street in accordance with the Comprehensive Land Management Code for the Township of Galloway, and no other owner of lots also contiguous to the proposed street voluntarily agrees in or joins with the applicant within a thirty-day period of said request, the sole applicant shall then be granted the opportunity to request and receive a variance from the Zoning Board of Adjustment, as set forth below, to obtain said building permit for construction on said lot and to construct a gravel road. Should the variance be granted, then and in such event, until such time as at least one other owner of a lot contiguous to said proposed street also applies for a building permit and/or requests the construction of said street in accordance with the Comprehensive Land Management Code for the Township of Galloway, neither the original applicant nor the Township shall be required to construct a street in accordance with the provisions of the Comprehensive Land Management Code for the Township of Galloway, and the applicant shall have no other duties or responsibilities hereunder, except those responsibilities and duties of maintenance as set forth in Subsection E(7) above and the provisions of this Subsection E(10).
(b)
Such an application as hereinabove set forth
to the Zoning Board of Adjustment for the Township of Galloway to
seek a building permit and a permit to construct and maintain a gravel
road shall be heard and disposed of by the Zoning Board of Adjustment
in the same manner as though the applicant were applying for a variance
in accordance with the provisions of N.J.S.A. 40:55D-70. In the event
that said variance shall be granted by the Zoning Board of Adjustment
to the applicant, the conditions for granting said variance to permit
construction of a building and to permit the construction and maintenance
of a gravel road shall include but shall not be limited to the following:
[1]
The applicant must improve the entire extension from the furthest end of his property line to the nearest street with a gravel surface, in accordance with the standards set forth in Article VII, § 233-44C of the Land Management Code for the Township of Galloway, including, without limitation, gravel of a compact depth of six inches.
[2]
The applicant is to ensure adequate access for
fire-fighting equipment, ambulances and other emergency vehicles necessary
for the protection of health, safety and welfare.
[3]
The roadbed of such extension must follow those
street lines presently established on the Official Map and official
Tax Map of the Township of Galloway.
[4]
The applicant must apply and obtain appropriate
permits from the Atlantic Soil Conservation District and/or any other
permits as may be required by the County of Atlantic and/or State
of New Jersey.
(c)
In the event that an applicant was previously granted a variance consistent with the provisions of this new Subsection E(10), and in all other respects can prove to the governing body of the Township of Galloway that his and/or her situation is consistent with that as envisioned by this subsection, then he and/or she shall not be required to reapply for a variance but shall be permitted to apply for a building permit both for the construction of the building and for the construction of a gravel road upon the showing that he and/or she has complied with the conditions of the said variance as aforesaid.
(d)
In no event, however, shall the Zoning Board of Adjustment nor the governing body be permitted to grant a building permit to any subsequent owner of a contiguous lot immediately contiguous with the proposed street or any adjacent and connected paper street as shown on the Official Map and/or Tax Map of the Township of Galloway, which shall be a natural extension thereof, after one person has applied for and received the variance as provided for herein. Should any subsequent owner apply for a building permit for a lot immediately contiguous to the proposed and/or constructed gravel street and/or extension thereto as hereinabove set forth, said person shall not be permitted to apply for a variance to the Zoning Board of Adjustment as provided for herein, but all parties, including the party receiving or having received the variance, shall then strictly comply with the provisions of Subsection E(1) through (9) inclusive.
F.
Design of certain streets.

following requirements:
A.
All parking spaces to be a minimum area of 180 square
feet and a minimum of nine feet in width.
B.
Pavement construction.
(1)
In lieu of the two-inch penetration macadam, a two-inch
FABC surface pavement will be acceptable.
[Amended 2-19-1980 by Ord. No. 608]
(2)
Base material shall be a minimum of four inches of
soil aggregate, Type 5, Class A.
(3)
In instances where parking is demonstrated to be of
a temporary or occasional nature, this requirement may be waived by
the Planning Board.
Street signs of the type and design to be approved
by the Planning Board shall be installed at all street intersections.
[Amended 7-6-1982 by Ord. No. 700]
Curbs and/or gutters are required for major
subdivisions and planned developments, but may be waived by the Planning
Board if the applicant proposes an acceptable drainage system not
requiring curbs and/or gutters. They are not required for minor subdivisions,
except if such minor subdivision is located directly adjacent to land
on which curbs and/or gutters have been previously installed.
A.
As a minimum, the following type of construction is
acceptable for Township roads: Monolithic curb and gutter shall consist
of six-by-twelve-inch curb and a six-by-eighteen-inch gutter formed
and poured at one time. It shall be sufficiently reinforced to withstand
normal traffic loading.
B.
Installations on county roads shall meet county specifications.
C.
Whenever
the installation of curbs and/or gutters are required for residential
development pursuant to the Residential Site Improvement Standards,
N.J.A.C. 5:21-1.1 et seq., or by the Galloway Township Land Management
Code for nonresidential development, the Planning Board or, if applicable,
the Zoning Board may grant relief from the otherwise applicable requirement
for the installation of curbs and/or gutters. For residential development
subject to the requirements of the Residential Site Improvement Standards,
the Board may waive such installation in accordance with N.J.A.C.
5:21-4.3. For nonresidential development, the Board may in its discretion
approve relief from the otherwise applicable requirement for the installation
of curbs or gutters in accordance with the Galloway Township Land
Management Code. If the Board grants relief from the requirement for
the installation of otherwise-required curbs or gutters, the applicant
shall as a condition of such relief pay to the Galloway Township Sidewalk
and Pedestrian Path Fund an amount equivalent to 50% of the cost of
the otherwise-required curb or gutter installation. Such amount shall
be calculated as of the time of the approval in accordance with the
Township Engineer's estimate of cost.

The developer shall have incorporated in his design the requirements for streetlighting in accordance with the recommendations of the Planning Board, and such streetlighting plan shall be approved by the Township Engineer and the Planning Board. The developer shall pay to the Township the costs of operation of said streetlights as determined from the standard rates of the utility. This payment for operation shall continue until such time as the street upon which said lights are installed shall be accepted by ordinance of the Township governing body as a public street of the Township of Galloway. Additionally, the developer shall bear the installation and construction costs of all new streetlighting or any changes to existing streetlighting necessitated by the development, and the furnishing of an adequate performance guaranty pursuant to § 233-65 of this chapter may be required as condition of approval. The costs of such streetlighting shall include, in addition to new poles, underground or aboveground wiring and similar expenses and the cost of lighting fixtures pursuant to currently approved Board of Public Utility rate schedules for the utility.

A.
Whenever the installation of sidewalks is required for residential
development pursuant to the Residential Site improvement Standards,
N.J.A.C. 5:21-1.1 et seq., or by the Galloway Township Land Management
Code for nonresidential development, the Planning Board or, if applicable,
the Zoning Board may grant relief from the otherwise applicable requirement
for the installation of sidewalks. For residential development subject
to the requirements of the Residential Site Improvement Standards,
the Board may approve a de minimis exemption in accordance with N.J.A.C.
5:21-3.1. For nonresidential development, the Board may in its discretion
approve relief from the otherwise applicable requirement for the installation
of sidewalks in accordance with the Galloway Township Land Management
Code.
B.
The reviewing board may approve either a de minimis exemption or
a waiver of site improvement standards so as to eliminate the requirement
for the installation of sidewalks if the following conditions are
satisfied.
(1)
There are neither existing sidewalks contiguous to the site, nor
any sidewalks proposed or reasonably likely to be constructed contiguous
to the site within the foreseeable future.
(2)
Sidewalks at the location are not necessary for public safety or
otherwise to serve the public interest.
(3)
The public interest would be better served by the installation of
sidewalks at another location.
C.
If the Board grants relief from the requirement for the installation
of sidewalks, the applicant shall as a condition of such relief pay
to the Galloway Township Sidewalk and Pedestrian Path Fund an amount
equivalent to 50% of the cost of the otherwise required sidewalk installation.
Such amount shall be calculated as of the time of the approval in
accordance with the Township Engineer's estimate of cost.
D.
Sidewalk and Pedestrian Path Fund.
(1)
There is hereby created a separate Sidewalk and Pedestrian Path Fund
for the purpose of depositing contributions collected from residential
and nonresidential developers when the Planning Board or the Zoning
Board has granted relief from the requirement for the installation
of sidewalk or curbs/gutters. All contributions paid by applicants
pursuant to this section shall be deposited into this fund.
(2)
Funds deposited in the Sidewalk and Pedestrian Path Fund may be used
for the installation of sidewalks, for the installation of other pedestrian
paths, for the installation of curbs or gutters, or for other necessary
and appropriate infrastructure improvements. Emphasis shall be given
to the extension or improvement of existing sidewalks.
In lieu of sidewalks, bike paths may be required
as shown on the Galloway Township Recreation Plan, an element of the
Master Plan, depending on the development's location in relation to
schools, recreation areas, shopping facilities and other populated
areas. Bicycle traffic shall be separated from motor vehicle and pedestrian
traffic as much as possible. Bikeways shall generally not exceed a
grade of 3%, except for short distances, and shall be a minimum of
six feet wide. Bikeways shall have a minimum four-inch base of crushed
stone and a two-inch FABC-2 surface course. Where bike paths intersect
a street, the curbing (where applicable) shall be ramped for access
to the street grade.
A.
Shade trees shall be located in the front yard limits, so as not to interfere with utilities or sidewalks, and shall be one of the following types: oak, hard maple or other deciduous variety approved by the Planning Board. In the Pinelands Area landscaping shall be in accordance with § 233-83B. There shall be a minimum of two such trees properly planted, fertilized and staked for each 100 feet of road frontage, unless an equivalent number of trees are preserved within 50 feet of the road right-of-way.
[Amended 9-9-1986 by Ord. No. 828]
B.
If the lot or site contains one or more specimen trees
(16 inches caliper), the siting of the structure(s) shall be such
as to preserve the maximum number of specimen trees. This requirement
may be waived by the Planning Board in the case of wooded sites.
[Added 3-28-2000 by Ord. No. 1416; amended 8-28-2001 by Ord. No. 1482; 5-9-2006 by Ord. No. 1654]
A.
Purpose.
(1)
The Township Council of the Township of Galloway,
believing that inadequate tree density, whether occurring by natural
causes, or as currently existing on public land throughout the Township,
or due to indiscriminate, uncontrolled and excessive destruction,
removal and cutting of trees upon lots and tracts of land within the
Township, causes increased drainage control costs, increased soil
erosion and sedimentation, decreased fertility of the soil, degradation
of water resources, decreased groundwater recharge, increased buildup
of atmospheric carbon, and increased dust tending to impact the character
and aesthetic value of the Township and decrease property values,
all of which render land unfit and unsuitable for its most appropriate
use and adversely affect the health, safety, enjoyment and general
welfare of the inhabitants of the Township, desires to regulate and
control unnecessary, indiscriminate, or excessive cutting of trees
within the Township, replace and preserve the maximum possible number
of trees in the course of development of a site and throughout the
Township, protect larger, older specimens of trees, encourage the
replanting and preservation of trees on public lands throughout the
Township, enhance the replenishment of atmospheric oxygen, prevent
the spread of tree disease or infestation to healthy trees on development
sites and on public lands throughout the Township, and encourage innovative
design and grading to promote the preservation of existing trees.
(2)
It is recognized that there is a strong relationship
between the integrity of the Township and the region's water resources
and air quality and the development on steep slopes, tree removal,
replanting and health, soil disturbance, stormwater management and
the general use of land resources. Therefore, the appropriate management
of these resources is an important health, safety, and general welfare
concern.

to, wetlands as defined by N.J.S.A. 13:9B-1 et seq. Exceptions for
extreme hardships may be made by the Planning Board at its discretion
C.
Restrictions.
(1)
Cuffing or removal. With the exception of the exemptions set forth in § 233-52E, no person shall cut or remove, or cause to be cut or removed, any existing tree with a diameter at point of measurement (DPM) of eight inches or greater upon any lands within the Township unless the cutting or removal can be accomplished in accordance with the provisions of this section.
(2)
Other restrictions. Causing death to any tree for
any reason or by any means whatsoever whether directly or indirectly,
purposefully or accidentally, shall be considered the equivalent of
purposefully cutting and clearing that tree.
D.
Removal of trees; permit required.
(1)
With the exception of the exemptions set forth in § 233-52E and subject to the provisions of § 233-52E, no tree shall be cut or otherwise removed from any lands in the Township without a tree removal permit. All applications to an agency for approval of a major subdivision, minor subdivision, or any site plan requiring tree removal, unless otherwise exempt pursuant to this chapter, shall include an application for a tree removal and protection permit. All applications for tree removal and protection permits, whether in conjunction with major or minor subdivisions, site plan applications, or otherwise, shall be made to the Zoning Officer of Galloway Township for referral to the approving agency. No tree that was planted or preserved as part of any landscape plan or in accordance with any street requirements approved in conjunction with a subdivision or site plan shall be removed, except for such trees directed to be removed pursuant to § 233-52E(6), (7) and (9) below.

property that is carried out pursuant to this section of the ordinance
and is not part of an application for subdivision or site plan shall
preclude said property from being the subject of a development application
for a period of two years from the date of clearing so as to discourage
"pre-clearing" of property and circumventing the provisions of this
section. Unless the owner of a property which has been cleared in
excess of the limitations set forth in this section notifies the Township
Zoning Officer in writing at least two years in advance of becoming
an applicant for development of any kind on the property in question,
such failure to provide adequate notice of clearing at least two years
prior to becoming an applicant will be grounds for the Township construction
office or Planning and/or Zoning Boards to find any application for
construction or development incomplete. Such adequate notice shall
be sent by certified mail at any time. However, any application for
construction or land development will not be deemed complete until
two years after adequate notice has been provided.
E.
Exemptions. The following shall be exempt from the
requirements of this section:
(1)
Commercial nurseries and fruit orchards.
(2)
Christmas tree farms.
(3)

as indicated on the official Galloway Township Zoning Map.
(8)
Trees removed in conjunction with farmland greater than five acres in size that will be actively devoted primarily to agricultural uses and that produces a minimum annual gross revenue of $500 per acre from said farming activities. Nonetheless, an inventory of trees per § 233-52C to be removed, identified by size and species, shall be prepared and filed with the Township Planning/Zoning Department prior to any tree removal. In the event the farmland is not actively devoted primarily to farming activities for a continuous period of seven years following tree removal, the tree replacement provisions contained in § 233-52F(4) shall apply.
(9)
Development projects for which applications have been
deemed complete on or before the effective date of this section.
(10)
The following exemptions apply to single-family

no other alternative but to place a structure outside the permitted
building setbacks.
(b)
Where the location of an existing tree negatively
impacts on an existing septic field.
(c)
Where no other alternative exists for the placement
of a septic field, driveway, deck, patio, lawn area, or swimming pool
or the recreational use by the inhabitants of the dwelling, or any
other authorized improvements but in the vicinity of an existing tree.
(11)
The following tree species shall be exempt from
the provisions of the section concerning preservation in a disturbed
area, unless the Township determines a specific tree is a unique specimen:
(Reserved)
F.
Tree removal/protection requirements for major and
minor subdivisions and site plans.
(1)
Application review procedure. Every application to
an agency for approval of a major subdivision, minor subdivision,
or any site plan that requires the removal of trees of DPM of eight
inches or greater shall be accompanied by a tree preservation plan.
This tree preservation plan (the plan) shall accompany the application
to the agency. The plan is for agency consideration; its approval
in conjunction with subdivision or site plan approval does not constitute
a permit for tree removal. Subsequent tree removal and protection
permit applications are to be made for each right-of-way (ROW, a street
or similar path offering ingress or egress to the lots of the development),
for each easement, and for each lot of the subdivision or site, or
group thereof, as applicable, as each lot or group is to be developed.
Said applications shall conform to the plan as approved and may be
grouped as desired by the applicant in accordance with the approved
plan, as one permit application, except that the clearing of each
lot or group of lots within a subdivision shall take place on an individual
basis separate from ROW clearing, and clearing for areas outside of
the residential lot areas, requiring a separate permit application.
The plan shall include a map, at a scale no finer than one inch equals
30 feet, prepared by either a land surveyor, or a professional engineer
or planner licensed by the State of New Jersey, and shall include:

For all ROWs those trees within a thirty-foot
limit of disturbance of ROWs or underground or exposed utility lines,
so as to preserve specimen trees;
[2]
For all individual lots or groups thereof, all
noted trees within the area of disturbance and those located within
an area 30 feet outside the area of disturbance.
(c)
Specific proposals for replanting or replacements,
if applicable;
(d)
The location of streams and water courses; and
(e)
The location of slopes with grades steeper than
15% from which trees are to be removed.

lot, etc.);
[6]
Such other information as may be deemed necessary
in order effectively to process and decide such application; and
[7]
Claims for exemptions and provision for supporting
information. Where a highly-desirable specimen tree is worthy of preservation,
an applicant may submit a variance application to the appropriate
agency without cost to provide flexibility for relocating a structure
outside of the building envelope.
(b)
Landscape plan.
[1]
The following information shall be provided on a landscape plan prepared in accordance with § 233-36E of this chapter:
[a]
Location of tree canopy within
the property boundaries. Tree canopy is defined as including any deciduous
or coniferous species existing at the time of application with a DPM
of four inches or greater.
[b]
Location and identification by size and species of individual trees as listed in § 233-52F(2)(a)[4] for removal, plus those trees of DPM of 12 inches or greater within the area of development/limit of disturbance which are to be preserved.
[c]
Clear labeling of the entire area
intended for tree removal/protection.
[d]
Limit of disturbance line.
[e]
Areas reserved for topsoil stockpiling
and storage of construction equipment.
[f]
Identification of proposed structures,
utility lines, waste lines, septic fields, if applicable, and fuel
storage tanks, if applicable.
[2]
The landscape plan is to accompany the submission
of the application.
(c)
Submission. The application and landscape plan
is to be filed with the Office of Township Engineer or Planner and
the Office of Township Planning/Zoning Board for each ROW, for each
easement, and for each individual lot or group of lots in the subdivision
or on the site plan, as applicable.
(3)
Clearing requirements.
(a)
Design requirements.
[1]
Only those trees necessary to permit the construction
of buildings, structures, streets, driveways, infrastructure, and
other authorized improvements shall be removed. Existing vegetation
shall be preserved to the greatest extent feasible. Trees located
beyond 30 feet of a building foundation, septic system, or driveway
shall be preserved, unless an exemption is granted.
[2]
Existing tree canopy clearing.
[a]
Residential development.
[i]
For residential development, no
more of the existing tree canopy within the property boundaries shall
be removed beyond the limits in this subsection. Existing tree canopy
comprised of the remaining lot area shall be noted for preservation.
[ii]
The permitted clearing limits
for residential development shall be either 10% greater than the allowable
site coverage, or 10% less than the open space requirement, expressed
as a percentage of site area, whichever is greater. The Planning and/or
Zoning Board will also consider the extent to which the proposed landscaping
plan ameliorates the impact of the tree clearing and determine whether
additional landscaping requirements may be necessary at the time of
site plan or subdivision review.
[b]
For commercial development, tree
protection shall be determined on a case-by-case basis, upon review
of the applicant's tree removal and preservation plan, in accordance
with the requirements of this chapter and the quality of landscaping
proposed with the development. The combination of selective tree clearing
and quality and quantity of landscaping will be considered by the
Planning Board, evaluating each proposal on the basis of its appearance
to the community as a commercial development.
[3]
Landscape standards may be waived by the Planning
Board when trees and/or shrub masses are preserved and/or relocated
on-site that duplicate or essentially duplicate the landscape requirements
contained in this section. Existing trees and/or shrub masses preserved
within wetlands, wetland transition areas, or other use-restricted
areas are excluded.
[4]
Any appropriate Township reviewing authority
shall have the option of requiring a conservation easement to protect
any or all trees or tree canopy areas to remain on site.
[5]
A healthy historic tree, or an endangered species
or specimen tree, shall be preserved to an extent reasonably possible
by the modification of lot development plans. If such modification
requires a variance, a variance application may be made to the appropriate
agency without costs.
(b)
Site protection.
[1]
Tree protection measures and the limit of disturbance
line shown on the landscape plan shall be provided in the field with
snow fencing or other durable material and verified by a designated
representative of the Office of the Township Engineer or Planner prior
to soil disturbance. For purpose of enforcement the designated representative
of the Township shall be the Township of Galloway Engineer or Planner
or his designee.
[2]
Protective barriers shall not be supported by
the plants they are protecting, but shall be self-supporting. Barriers
shall be a minimum of four feet high and last until construction is
complete.
[3]
Chain link fence may be required for tree protection
if warranted by site conditions and the relative rarity of the plant.
[4]
Snow fencing used for tree protection shall
be firmly secured along the drip line, but not less than six feet
from the trunk.
[5]
The grade of the land located within the drip
line shall not be raised or lowered more than six inches unless compensated
by welling or retaining wall methods; and in no event shall welling
or retaining wall methods be less than six feet from the trunk of
a tree.
[6]
No soil stockpiling, storage of building materials,
construction equipment or vehicles shall be permitted within the drip
line or within six feet of any existing tree to be preserved, whichever
is greater.
[7]
No equipment shall be operated within six feet
of any tree protected by this chapter, nor shall such equipment be
operated at any time in such a manner as to break, tear, bruise, decorticate,
or otherwise injure any living or dormant tree. Any clearing within
the drip line, or within six feet of the trunk of a remaining tree,
whichever is greater, shall be done by hand-operated equipment. Excavating
operations within four feet of any tree requires a separate permit
from the Office of the Township Engineer or Planner.
[8]
Parasitic growth, such as clinging vines, are
to be removed from all trees noted for preservation and which are
to be protected as required herein. Such removal is an ancillary requirement
of the granting of a clearance permit.
(4)
Tree care and plantings.
(a)
Tree replacement and reforestation.
[1]
Where clearing and/or construction on the site
results in accidental or deliberate removal or severe damage which
will eventually result in the death of any tree noted for preservation,
the developer shall replace the tree(s) in accordance with the following
table in accordance with its approved subdivision or site plan:
DPM of Existing Tree Removed
(inches)
|
Minimum Number of Replacement Trees
| |
---|---|---|
Less than 8

[2]
Replacement tree(s) shall be located on site.
[3]
All trees required for planting by this § 233-52F(4) shall be of a hardwood deciduous species indigenous to the area, of a minimum 2 1/2 inch caliper, unless alternatives are granted by the appropriate approving authority such as the Planning or Zoning Board, or the Office of Township Engineer on a case-by-case basis.
(b)
Damage assessment. When a tree noted for preservation has been inadvertently damaged during construction, the developer or owner shall take immediate steps to preclude resultant tree death. Such steps shall include staking, bark painting, and deep-root fertilization and/or pruning under the direction of a licensed arborist. However, where the Township authority determines after field investigation that a large specimen tree, having sustained significant damage such that there is doubt concerning its chances for long-term survival, the provisions of § 233-52F(4)(a)[2] apply.
(c)
Pollution recovery. For every residential, commercial,
or industrial site development, the plan shall include the addition
of one tree for every four parking spaces.
(d)
Bonding for tree replacements. The developer or property owner shall post a bond, of $200 per replacement tree, at the time of requesting a CO, if such replacements are not installed. A conditional CO may be issued pending such replacements. Conditional COs will be made final COs upon full replacement installation with return of bond money, or after one year if no replacements are installed with forfeiture of bond money to the Tree Bank Fund of § 233-52H(2).
(e)
Township option. If the Township should decide that the applicant will not be required to replace the required trees on his site, the Township may require the applicant to contribute $200 per tree not replaced, which monies shall be deposited into the Tree Bank Fund of § 233-52H(2).
(5)
Tree removal requirements for cluster and planned development. The standards and procedures of § 233-52F and its subsections shall be followed for cluster and planned development, except for § 233-52F(3)(a)[2].
G.

(1)
Applicability. Except as provided in § 233-52D(2), any residential lot that is less than 20,000 square feet and is removing more than five trees with DPMs between eight inches and 12 inches, and any number of trees of DPM greater than 12 inches, in any consecutive two-year period, and any residential lot that is 20,000 square feet or greater and is removing trees encompassing more than 10% of the lot area, in any consecutive two-year period, shall submit an application for a tree removal/protection permit to the Office of the Township Engineer or Planner. The application and development proposal shall conform to the provisions contained herein.
(2)
Application form.
(a)
The tree removal/protection application form
shall be available from the Zoning Officer and the Office of the Township
Engineer or Planner, and shall be identical to that required for major/minor
subdivisions and site plans, and shall require all of the same information
to be provided.
(b)
Where a highly desirable specimen tree is worthy
of preservation, an applicant may submit a variance application to
the appropriate agency without cost to provide flexibility for relocating
a structure outside of the building envelope.
(3)
Sketch data. A sketch shall be provided with the application
showing the location of the tree(s) to be removed with a DPM of 12
inches or greater and its proximity to existing and/or proposed structures
and property lines. The sketch shall also show areas reserved for
topsoil stockpiling and storage of construction equipment.
(4)
Design requirement.
(a)
Trees to be removed shall be only those trees
necessary to permit the construction of buildings, structures, decks,
driveways, septic fields, lawn area, swimming pools, and the like.
(b)
Existing vegetation shall be preserved to the
greatest extent feasible. Trees located beyond 30 feet of a building
foundation, septic system, or driveway shall be preserved, unless
an exemption is granted by the receiving agency.
(c)
Section 233-52G(6) of this section shall be considered in the decision to permit the removal of any regulated trees.
(5)
Site protection. Site protection measures shall be provided in accordance with § 233-52F(3)(b).
(6)
Additional tree removal criteria. In addition to the
design requirements stated above, the Township or its Engineer or
Planner may grant a tree removal permit based upon one or more of
the following circumstances: (Reserved)
(7)
Review by Zoning Board. If, in the opinion of the
Township or its Engineer or Planner, the request for tree removal
does not satisfy any of the above criteria, the applicant may request
that the application be forwarded to the Zoning Board for action.
Decisions of the Zoning Board are final.
(8)
Tree replacement.
(a)
For every tree removed with a DPM of eight inches
or greater but less than 18 inches, either as not approved by application
or accidentally injured during construction, a replacement tree shall
be planted on the residential lot under an approved permit. Said replacement
shall be of minimum 2 1/2 inch caliper, shall be of species similar
to that of the tree removed, and shall be planted within the two-year
time period associated with the application.
(b)
For every tree removed with a DPM of 18 inches
or greater, either as approved by application or accidentally injured
during construction, two replacement trees shall be planted on the
residential lot. Said replacements shall be of a minimum of 2 1/2
inch caliper, shall be species similar to that of the tree removed,
and shall be planted within the two-year time period associated with
the application.
(c)
The developer or property owner shall post a bond of $200 per required replacement tree at the time of submitting the request for a tree removal/protection permit, to satisfy the requirements above. Bond money will be returned upon the full completion of tree replacements. Bond monies will be forfeited to the Tree Bank Fund of § 233-52H(2) if full replacements are not completed within two years of the granting of the tree removal/protection permit.
(9)
Township option. If the Township should decide that the applicant will not be required to replace the required trees on his site, the Township may require the applicant to contribute $200 per tree not replaced, which monies shall be deposited into the Tree Bank Fund of § 233-52H(2).
H.
Fees.
(1)
Applications made for permits in accordance with §§ 233-52F(2) and 233-52G(2) of this chapter shall be accompanied by the payment of a fee for the application to be considered. Fee levels are to be set from time to time by the Galloway Township Council.
(2)
Additionally, the Township shall maintain a Tree Bank
Fund as a depository for monies as specified in this chapter.
I.
Review standards.
(1)
Granting of permits.
(a)
In addition to any design requirements provided
in this chapter and unless otherwise indicated herein, a tree removal
permit may be granted for the following reasons and under the following
terms and conditions:
[1]
That the continued presence of such tree or
trees is likely to cause danger to persons or property upon the property
for which removal is sought, or upon adjoining or nearby property.
[2]
That the area where such tree or trees are located
has a cut, depression or fill of land, or the topography of the land
is of such a character as to be injurious or dangerous to such tree
or trees, or to trees, or to a tree or trees located nearby.
[3]
That the removal of trees is for the purpose
of conducting forestry activities, which activities include, but are
not limited to, the harvesting of trees in accordance with a forest
management plan and the thinning out of a heavily wooded area, with
some trees to be removed, and other trees to remain.
(b)
Tree removal is conditioned on an express finding
by the Township or its Engineer or Planner that the proposed removal
will not result in or cause, increase, or aggravate any or all of
the following conditions: impaired growth or development of remaining
trees or shrubs on the property of the applicant, or upon adjacent
property; soil erosion, sedimentation, and dust; drainage or sewerage
problems; or dangerous or hazardous conditions.
(c)
The Township or its Engineer or Planner shall
have the power to affix reasonable conditions to the granting of any
permit for the removal of trees. New Jersey certified tree experts
may be consulted to recommend specimen trees to be preserved as well
as to identify trees with questionable survival rates.
(2)
Certification. Upon certification by the Township
Engineer or Planner that one or more trees located on lands in the
Township, either public or private, are diseased or harboring destructive
insects and should be destroyed because of danger of further infection
or infestation of additional trees upon same or adjoining lands, the
Township Engineer or Planner may, with or without the consent of the
owner of the lands involved if private, order the destruction and/or
removal of said tree(s), provided the lands involved are restored
to their original condition using nursery stock that has been set
aside by the tree banking program.
J.
Permit approval.
(1)
Time for approval.
(a)
Where the plan is submitted as a part of an
application for major subdivision, minor subdivision or site plan
approval, the time for approval shall be governed by the timing requirements
applicable to major subdivisions, minor subdivisions or site plans.
(b)
Where the application for a tree removal and protection permit is made subsequently for ROWs, easements, or for lots or groups of lots of a subdivision or site, or in connection with a single-family lot (not part of a major or minor subdivision), the Township or its Engineer or Planner shall act on the application within 20 days of its receipt or within such additional time as consented by the applicant. Failure to act within 20 days, or any extension thereof, shall be deemed to be an approval of the application and thereafter the Township or its Engineer or Planner shall issue a tree removal permit based thereon. However, no tree removal activity shall be undertaken until the inspection requirements of § 233-52L shall have been satisfied. A copy of the signed application shall be sent to the applicant as a permit.
(2)
Denial. No approval of a plan submitted to an agency
shall be granted if the agency finds that the proposed tree removal
Plan is contrary to the best interests of the public health, safety,
or general welfare.
K.
Duration of permits.
(1)
Permits granted for the removal/protection of trees
under the terms and conditions of this section shall run with the
land, and shall remain in force and effect for the following periods
of time, and not thereafter.
(a)
If granted for a lot or parcel of land for which
no building permit is required: one year from the date of issuance.
(b)
If granted for a lot or parcel of land for which
a building permit is required, but for which no site plan approval
is required by the Township Planning Board: until expiration of the
building permit granted with such tree removal permit.
(c)
If granted for a lot or parcel of land for which
site plan approval from the agency is required as a condition precedent
to obtaining a building permit: until expiration of the site plan
approval, or expiration of the building permit issued after such site
plan approval, whichever comes first.
(d)
If granted for a lot or parcel of land for which
minor subdivision is sought: one year from the date of granting such
minor subdivision approval.
(e)
If granted for a lot or parcel of land for which
preliminary approval of a major subdivision is sought: until expiration
of such approval.
(2)
Any new lot created by way of subdivision will have
to comply with the requirements of this section of the ordinance;
as such the developer will be required to submit a tree protection
plan for each individual lot. As this plan, having been approved by
the Township, will indicate trees that are to be preserved, the developer
must attest to that fact that he/she has informed the potential lot
purchaser that no further clearing of the property may be done for
a period of two years without being subject to the penalty section
of the ordinance.
L.
Inspection.
(1)
Pre-permit.
(a)
Prior to taking final action upon any application
for tree removal and protection, an inspection of the site shall be
made by:
(b)
Such inspections shall be made of the site referred
to in the application, and of contiguous and adjoining lands, as well
as of lands in the vicinity of that of the application, for the purpose
of determining drainage conditions and physical conditions existing
thereon.
(2)

(2)
Should any tree requiring the issuance of a removal/protection permit be removed without such permit, the Township or its Engineer or Planner shall, in addition to any other enforcement measures taken per Subsection M(1)(a) through (d) above, issue a tree removal summons returnable in Municipal Court to the property owner(s) or person(s) exercising dominion and control over the property and any contractor(s) or individual(s) who actually removed said trees. The tree removal municipal summons shall expose the aforesaid persons and/or entities to penalties on a per-tree basis for each individual tree removed without the requisite tree removal/protection permit.
(3)
Upon conviction in Municipal Court for removal of
any tree without the requisite removal/protection permit, the property
owner and/or person(s) exercising dominion and control over the property
and/or any person(s) who actually cuts down such tree, shall be subject
to a fine of a minimum of $500 to a maximum of $1,250 for each tree
cut down or removed, whichever is greater.
N.
Tree Bank Fund management.
(2)
Tree Bank funds at a particular location shall be
allocated and expended with the following priority:
(a)
Replacing trees identified by the Township Engineer
or Planner or personnel approved by the Township Engineer or Planner
as having suffered damage sufficient to kill, or eventually kill,
them due to the applicant's development activities;
(b)
Planting trees where the Township Engineer or
Planner or personnel approved by the Township Engineer or Planner
have determined there is inadequate forestation;
(c)
Removing and replacing frees identified by the
Township Engineer or Planner or personnel approved by the Township
Engineer or Planner that are dead, dying or diseased;
(d)

by Section 4 of Chapter 358 of the Laws of 1953[1] and shall be placed in accordance with said statute.
[Last amended 4-13-2021 by Ord. No. 2043-2021]
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.
(a)
It is hereby determined that the lakes and waterways within
the Township of Galloway of Atlantic County may be subject to flooding;
that development tends to accentuate the possibility of such flooding
by increasing stormwater runoff, due to alterations of the hydrologic
response of the watershed in changing from the undeveloped to the
developed condition; that such increased stormwater runoff produced
by development of real property contributes to the possibility of
increased quantities of waterborne pollutants and tends to increase
channel erosion; that such increased stormwater runoff, increased
erosion potential and increased pollution potential constitutes the
possibility of the deterioration of water resources of the Township
of Galloway, the County of Atlantic and the State of New Jersey; and
that such impacts can be controlled to some extent by the regulation
of stormwater runoff from such development. It is determined that
it is in the public interest to regulate the development of real property
and to establish standards to regulate the additional discharge of
stormwater runoff from such developments as provided in this section.
(b)
Certain areas of Galloway Township lie within the Pinelands
Region of the Township, and therefore development in the portion of
Galloway Township is subject to the requirements of the Pinelands
Protection Act (N.J.S.A. 13:18A-1 et seq.) and implementing regulations
and minimum standards contained in the Pinelands Comprehensive Management
Plan (CMP) (N.J.A.C. 7:50-1.1 et seq.). The purchase and intent of
these regulations and standards is to promote the orderly development
of the Pinelands Protection Area so as to preserve and protect the
significant and unique natural, ecological, agricultural, archaeological,
historical, scenic, cultural and recreational resources of the Pinelands.
(c)
It is the purpose of this section to establish minimum stormwater management requirements and control for major development, as defined in Subsection B, while all development not defined as a major development in Subsection B is required to meet or exceed those general requirements for stormwater management as stated in Subsection C. All developments are required to meet those standards for structural and nonstructural stormwater management measures as employed.
(3)
Goals and techniques
(a)
Through this section, the Township of Galloway has established
the following goals for stormwater control:
[1]
To reduce flood damage, including damage to life and property;
[2]
To minimize any increase in stormwater runoff from new development;
[3]
To reduce soil erosion from any development or construction
project;
[4]
To assure the adequacy of existing and proposed culverts and
bridges, and other in-stream structures;
[5]
To maintain groundwater recharge;
[6]
To minimize any increase in nonpoint pollution;
[7]
To maintain the integrity of stream channels for their biological
functions, as well as for drainage;
[8]
To restore, protect, maintain and enhance the quality of the
streams and water resources of the Township of Galloway and the ecological
character and quality of the Pinelands Areas;
[9]
To minimize pollutants in stormwater runoff from new and existing
development in order to restore, protect, enhance and maintain the
chemical, physical and biological integrity of the surface and groundwater's
of the Township of Galloway, to protect public health and to enhance
the domestic, municipal, recreational, industrial and other uses of
water; and
[10]
To protect safety through the proper design and
operation of stormwater management basins.
(b)
In order to achieve the goals for stormwater control set forth
in this section, the Township of Galloway has identified the following
stormwater management techniques:
[1]
Implementation of multiple stormwater management best management
practices (BMPs) may be necessary to achieve the performance standards
for stormwater runoff quantity and rate, groundwater recharge, erosion
control, and stormwater runoff quality established through this section.
[2]
Compliance with the stormwater runoff quantity and rate, groundwater
recharge, erosion control, and stormwater runoff quality standards
established through N.J.A.C. 7:8-1.1 et seq., and this section, shall
be accomplished to the maximum extent practicable through the use
of green infrastructure best management practices (GI BMPs) and nonstructural
BMPs before relying on structural BMPs. Nonstructural BMPs are also
known as "low-impact development (LID) techniques."
[3]
Green infrastructure best management practices (GI BMPs) and
nonstructural BMPs shall include both environmentally sensitive site
design and source controls that prevent pollutants from being placed
on the site or from being exposed to stormwater.
[4]
Source control plans shall be developed based upon physical
site conditions and the origin, nature and the anticipated quantity
or amount of potential pollutants.
[5]
Structural BMPs, where necessary, shall be integrated with nonstructural
stormwater management strategies and proper maintenance plans.
[6]
When using structural BMPs, multiple stormwater management measures,
smaller in size and distributed spatially throughout the land development
site, shall be used wherever possible to achieve the performance standards
for water quality, quantity and groundwater recharge established through
this section before relying on a single, larger stormwater management
measure to achieve these performance standards.
(4)
Applicability.
(a)
All development as defined in Subsection B of this section is subject to the standards and criteria established within this section. This includes all site and subdivision plans that require approval by the Township Planning and/or Zoning Board.
(b)
This section shall be applicable to all site plans and subdivisions
for the following major developments that require preliminary or final
site plan or subdivision review:
(c)
This section shall also be applicable to all major developments
undertaken by the Township of Galloway.
(d)
This section shall be applicable to all private properties,
other than residential lots with one single-family house, with respect
to storm drain inlet retrofitting, as set forth below.
(e)
The reviewing board or, in the case of individual dwellings or minor construction not subject to review by a board, the Construction Official may waive or adjust individual standards as may be reasonable and within the purpose of this section stated in Subsection A.
(f)
The applicant may request a waiver from the strict compliance
with the standards if it can be demonstrated and documented that the
enforcement of one or more of these standards will cause an undue
hardship.
(5)
Procedure.
(a)
Burden of proof. Whenever an applicant seeks a Township approval
of a development to which this section is applicable from any board
or official of the Township, that applicant shall be required to demonstrate
that the project meets the standards set forth in this section.
(b)
Submission materials due. The applicant shall submit materials, as required by Subsection J hereof, to the Township board or official from which the applicant seeks Township approval prior to or at the same time of submission of an application for Township approval.
(c)
Review. The applicant's project shall be reviewed by the Township
board or official from which the applicant seeks Township approval.
That Township board or official shall consult with the Township Engineer
to determine if the project meets the standards set forth in this
section.
(d)
Time for decision. The Township board or official shall promptly
determine if the project meets the standards set forth in this section.
The time for that determination should be the time permitted to review
and act on the applicant's application for a Township approval.
(e)
Failure to comply. Failure of the applicant to demonstrate that
the project meets the standards set forth in this section is reason
to deny the applicant's underlying application for a Township approval.
(6)
Compatibility with other permit and ordinance requirements.
(a)
Development approvals issued for subdivisions and site plans
pursuant to this section are to be considered an integral part of
development approvals under the subdivision and site plan review process
and do not relieve the applicant of the responsibility to secure required
permits or approvals for activities regulated by any other applicable
code, rule, act, or ordinance. In their interpretation and application,
the provisions of this 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)
In the event that a regional stormwater management plan(s) is
prepared and formally adopted pursuant to N.J.A.C. 7:8-1.1 et seq.
for any drainage area(s) or watershed(s) of which the Township of
Galloway is a part, the stormwater provisions of such a plan(s) shall
be adopted within one year of the adoption of a regional stormwater
management plan (RSWMP) as an amendment to an area wide water quality
management plan. Local ordinances proposed to implement the RSWMP
shall be submitted to the Pinelands Commission for certification within
six months of the adoption of the RSWMP per N.J.A.C. 7:8 and the Pinelands
CMP (N.J.A.C. 7:50).

from inland areas, but the depth of flooding generated by the tidal
rise and fall of the Atlantic Ocean is greater than flooding from
any fluvial sources. In some situations, depending upon the extent
of the storm surge from a particular storm event, a flood hazard area
may be tidal in the 100-year storm, but fluvial in more frequent storm
events.
The time it takes for runoff to travel from the hydraulically
most distant point of the drainage area to the point of interest within

Public Health Association, American Water Works Association and the
Water Pollution Control Federation. The term "TSS" shall have the
same meaning as "total suspended solids."
A neighborhood given priority access to state resources through
the New Jersey Redevelopment Authority.
A zone designated by the New Jersey Enterprise Zone Authority
pursuant to the New Jersey Urban Enterprise Zones Act, N.J.S.A. 52:27H-60
et seq.
Previously developed portions of areas:
The interstitial space between soil particles as calculated
by the ratio of the volume of voids to the volume of solids.
A structure within, or adjacent to, a water, which intentionally
or coincidentally alters the hydraulic capacity, the flood elevation
resulting from the two-, ten-, or 100-year storm, flood hazard area
limit, and/or floodway limit of the water. Examples of a water control
structure may include a bridge, culvert, dam, embankment, ford (if
above grade), retaining wall, and weir.
The upper surface of a zone of saturation.
The ocean and its estuaries, all springs, streams, wetlands,
and bodies of surface water or groundwater, whether natural or artificial,
within the boundaries of the State of New Jersey or subject to its
jurisdiction.

below the seasonally high water table and which has a depth which
is greater than its largest surface dimension.
A stormwater facility constructed through filling and/or
excavation that provides both permanent and temporary storage of stormwater
runoff. It has an outlet structure that creates a permanent pool and
detains and attenuates runoff inflows and promotes the settling of
pollutants. A stormwater retention basin can also be designed as a
multistage facility that also provides extended detention for enhanced
stormwater quality design storm treatment and runoff storage and attenuation
for stormwater quantity management. The term "stormwater retention
basin" shall have the same meaning as "wet pond."
Pursuant to N.J.A.C. 7:8-1.2, "wetlands" or "wetland" means
an area that is inundated or saturated by surface water or groundwater
at a frequency and duration sufficient to support, and that under
normal circumstances does support, a prevalence of vegetation typically
adapted for life in saturated soil conditions, commonly known as "hydrophytic
vegetation."

Editor's Note: See now N.J.A.C. 7:7-13.16.
C.
General standards. Design and performance standards for stormwater
management measures.
(1)
Stormwater management measures for major development shall be developed
to meet the erosion control, groundwater recharge, stormwater runoff
quantity treatment as follows:
(a)
The minimum 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 at N.J.A.C. 2:90.
(b)
The minimum standards for groundwater recharge, stormwater quality,
and stormwater runoff quantity shall be met by incorporating green
infrastructure.
(2)
The standards in this chapter apply to new major development and
are intended to minimize the impact of stormwater runoff on water
quality and water quantity in receiving water bodies and to maintain
predevelopment groundwater recharge levels. The standards do not apply
to new major development to the extent that alternative design and
performance standards are applicable under a regional stormwater management
plan or water quality management plan adopted in accordance with Department
rules.
(3)
In the Pinelands Area of the Township of Galloway, the following
criteria shall also apply:
(a)
There shall be no direct discharge of stormwater runoff from
any point or nonpoint source to any wetlands, wetlands transition
area or surface water body. In addition, stormwater runoff shall not
be directed in such a way as to increase the volume and rate of discharge
into any surface water body from that which existed prior to development
of the parcel.
(b)
To the maximum extent practical, there shall be no direct discharge
of stormwater runoff onto farm fields so as to protect farm crops
from damage due to flooding, erosion and long-term saturation of cultivated
crops and cropland.
(c)
Excessively and somewhat excessively drained soils as defined
by the Soil Conservation Service should be avoided for the recharge
of runoff wherever possible.
(d)
When and where possible, a positive gravity flow discharge structure/pipe
shall be constructed in such a manner so as to allow the complete
drainage of the retention/detention basin to a stream, storm sewer
or other point of positive drainage. This structure/pipe shall be
designed in such a manner that it may be locked closed and cause the
same effect as a dam to a lake. The locked condition shall keep the
stormwater from draining from the basin.
[1]
If the drainage structure/pipe is under Township ownership,
control and maintenance, it shall be the responsibility of the Director
of Public Works to determine when and if the structure/pipe must be
unlocked to drain the basin, to seek the approval of the Township
Committee to do so and to give public notice to the Pinelands Commission
if within the Pinelands Protection Area. The Director of Public Works
shall be responsible to keep the keys for these locks, to routinely
check to assure that they are normally locked and in good working
order and to relock them upon completion of the maintenance of the
basin.
[2]
If the drainage/pipe structure is under private ownership, control
and maintenance, it shall be the responsibility of the property owner
to request permission from the Township Committee to unlock this structure/pipe
and to give notice to the Pinelands Protection Area.
[a]
In order to obtain such permission to open the
locked structure/pipe, a statement, signed by the owner, must be presented
stating that it is in the public's best interest that this structure/pipe
be opened in order to drain the basin which has continued to retain
water beyond its normal period, and that it must be drained in this
manner to facilitate the maintenance of the basin. This statement
must also indicate the date on which the structure/pipe will be closed
and locked.
[b]
Upon receipt of such permission, the property owner
shall contact the Director of Public Works who shall exclusively maintain
the keys for the lock for this structure/pipe and shall unlock it
to drain and relock it upon completion of the maintenance of the basin.
(4)
Both retention and detention basins shall have the following improvements
as further specified in the NJ BMP Manual and in the New Jersey Department
of Transportation Standard Specifications for Road and Bridge Construction,
as amended, and New Jersey Department of Transportation Standard Construction
Details, as amended:
(a)
Headwalls and riprap.
(b)
A chain-link fence, four feet high, around the entire perimeter
may be required by the Board. In cases where a fence is required,
a twelve-foot opening shall be provided for vehicular access to streets
by means of a fifteen-foot-wide access right-of-way. The fence shall
not extend into the building front yard setback area.
(c)
An eighteen-inch berm around the inside of the basin.
(d)
Landscaping is required around the entire perimeter, except
where it faces planned open spaces or wooded areas or other natural
or man-made visual separation existing between the facility and adjoining
lands.
(5)
Wetlands.
(a)
No land development shall be carried out within 50 feet of a
wetland or in an area adjacent to a wetland area where the seasonal
high water table is three feet or less, unless the applicant can demonstrate
that the proposed development will not result in significant adverse
impact on any drainage structure.
(b)
A significant adverse impact shall be deemed to exist if:
(6)
Methods of management.
(a)
The following is a list of various control methods which may
be utilized in stormwater management systems, if appropriate. The
choice of control techniques is not limited to the ones appearing
on this list. However, it will be the policy of the Township to encourage
the use of retention basins wherever possible. All plans submitted
to the Township outside of the Pinelands Area must, if detention systems
are not the chosen method, explain why an alternate method is proposed.
(b)
The use of other control methods which meet the criteria in
this subsection will be permitted when approved by the Township Engineer.
Various combinations of methods should be tailored to suit the particular
requirements of the type of development and the topographic features
of the project area.
(c)
Regardless of the method used, the applicant will be required to provide a maintenance plan in accordance with Subsection K.
(d)
In addition to all other requirements of this subsection, each
applicant shall demonstrate that, at a minimum, existing trees and
vegetation on the development site will be preserved, protected and
maintained according to the minimum standards established by provisions
of the Township of Galloway Land Use Ordinance, Zoning Ordinance,
or by conditions of zoning or variance approval. Existing trees and
vegetation shall be protected during construction activities in accordance
with the Standard for Tree Protection During Construction provided
in the NJ State Soil Conservation Committee Standards for Soil Erosion
and Sediment Control in New Jersey, which is incorporated herein by
reference as amended and supplemented.
(e)
All submitted landscaping plans shall contain a revegetation
plan in accordance with the Pinelands CMP standards at N.J.A.C. 7:50-6.25(c).
(7)
Drainage easements.
(a)
All stormwater management plans shall illustrate the pathway
of positive outflow to the nearest stormwater easement, stream, lake,
pond or other natural watercourse. Prior to receiving final approval,
the applicant shall obtain the necessary easements corresponding with
the flow patterns illustrated on the plans should those patterns affect
the present or future use of adjoining parcels by increasing the quantity
of runoff over the adjoining parcel.
(b)
Where a subdivision is traversed by a watercourse, surface or underground drainage way or drainage system, channel or stream, there shall be provided and dedicated a drainage right-of-way easement to the Township conforming substantially to the lines of such watercourses, and such further width or construction, or both, as will be adequate to accommodate expected stormwater runoff meeting any minimum widths and locations shown on any adopted Official Map and/or Master Plan and, as a minimum, that fixed in Subsection B defined as "stream corridor." Such easement dedication shall be expressed on the plan as follows: "Drainage and utility right-of-way easement granted to the Management Ordinance of the Township of Galloway."
(c)
Drainage structures in county or state right-of-way. Drainage
structures which are located within state or Atlantic County highway
rights-of-way shall be approved by the state or county agency, and
a letter from that office indicating such approval shall be directed
to the Administrator of the Board and shall be received prior to the
final plat approval. Drainage structures abutting a brook or stream
whose drainage area, up to and including the subdivision or development,
is greater than 50 acres or within a 100-year floodplain shall be
required to secure a stream encroachment permit from the New Jersey
Department of Environmental Protection, in accordance with the latest
criteria, prior to authorization of final approval. A copy of said
permit shall be forwarded to the Administrator of the Board and attached
to the final engineering plans.
(d)
Minor subdivisions resulting in the construction of single-family
dwellings shall provide low maintenance measures to infiltrate the
volume of runoff generated by the additional impervious coverage for
the twenty-four-hour, ten-year storm event. The use of rain gardens
for the treatment of roof and driveway runoff is an acceptable alternative
to the installation of dry wells or other underground infiltration
facilities.
(e)
For minor subdivisions, at least one soil boring shall be completed for each lot proposing to incorporate infiltration BMPs. The soil boring should be completed in accordance with Subsection F.
(f)
Subdivisions proposing on-lot stormwater management facilities
shall provide a deed notice to future homeowners as to the location
and type of facility and a list of any potential inspection and maintenance
requirements.
(8)
Lot grading standards and as-built surveys.
(a)
Design and construction standards for lot grading.
[1]
All lots proposed for development, graded open spaces and planting
areas shall be graded to secure proper drainage and to prevent the
collection of stormwater. Grading shall be performed in such a manner
which will minimize the damage to or destruction of trees growing
on the land. Topsoil shall be provided and/or redistributed on the
surface as cover and shall be stabilized by seeding or planting. Grading
plans shall have been submitted with the preliminary and final plats,
and any departure from these plans must be approved in accordance
with the requirements of this section for the modification of improvements.
[2]
Wherever possible, the land shall be graded so that the stormwater
from each lot shall drain directly to the street via sheet flow through
disconnected pervious surfaces. If impossible to drain directly to
the street, it shall be directed to a system of interior yard drainage
designed in accordance with this section.
[3]
Unless otherwise required by this section, all tree stumps,
masonry and other obstructions shall be removed to a depth of two
feet below existing or finished grade, whichever is lower.
[4]
The minimum slope for lawns and disturbed areas shall be 1 1/2%
and, for smooth, hard finished surfaces other than roadways and parking
lots, 1/2 of 1%.
[5]
The maximum grade for lawns and disturbed areas within five
feet of a building shall be 10% and, for lawns more than five feet
from a building, 25%; except that, for the driveway, the maximum grade
shall be 15%.
[6]
Lots shall be graded to provide positive drainage from the rear,
side and front yard areas towards a downstream stormwater management
system. In no case shall lots discharge directly towards building
units of adjoining residential properties. In areas where conveyance
swales are required, the design shall be in accordance with the Standards
for Soil Erosion and Sediment Control in New Jersey and the stormwater
management provisions of this section.
[7]
Retaining walls installed in slope-controlled areas shall be
constructed of heavy timber or logs properly treated in accordance
with environmental regulations, reinforced concrete, reinforced masonry
or of other construction acceptable to the Board Engineer and shall
be adequately designed and detailed on the final plat to carry all
earth pressures, including any surcharges. The heights of retaining
walls shall not exceed 1/3 of the horizontal distance from the foundation
wall of any building to the face of the retaining wall.
(b)
As-built survey requirements.
[1]
As-built lot grading may be required for high-density developments
at the discretion of the approving authority. As-built surveys shall
be completed upon reaching final grade. Each survey shall be reviewed
by the Township Engineer to ensure compliance with the approved plans.
Any discrepancies from the approved plans must be addressed to the
satisfaction of the Township Engineer before the issuance of a certificate
of occupancy.
[2]
In the event the post-development condition of a project experiences
stormwater problems that in the opinion of the Township Engineer may
cause an impact to public health, safety or welfare, the Township
may request the developer to complete an as-built survey of the impacted
lot(s). Each as-built survey shall be reviewed by the Township Engineer
to ensure compliance with the approved plans. Any discrepancies from
the approved plans must be addressed to the satisfaction of the Township
Engineer and the impacted individual lot owner. No additional certificates
of occupancy will be provided until the impacts have been addressed
to the satisfaction of the Township.
D.
Stormwater management requirements for major development.
(1)
Stormwater management maintenance requirements. The development shall incorporate a maintenance plan for the stormwater management measures incorporated into the design of a major development in accordance with Subsection K.
(2)
Stormwater management measures shall avoid adverse impacts of concentrated
flow on habitat for threatened and endangered species as documented
in the Department's Landscape Project or Natural Heritage Database
established under N.J.S.A. 13:1B-15.147 through 13:1B-15.150, particularly
Helonias bullata (swamp pink) and/or Clemmys muhlenbergi (bog turtle).
(3)
The following linear development projects are exempt from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quantity requirements of Subsection D(16), (17), and (18):

is made of permeable material.
(4)
A waiver from strict compliance from the groundwater recharge, stormwater runoff quantity green infrastructures, and stormwater runoff quality requirements of Subsection D(7) 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;
(c)
The applicant demonstrates that, in order to meet the requirements of Subsection D(15), existing structures currently in use, such as homes and buildings, would need to be condemned; and
(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(7) 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 Subsections D(15), (16), (17) and (18). 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.
(6)

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 G(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 I(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, 5:21-7.4, and 5:21-7.5
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 I; and
(e)
The size of the orifice at the intake to the outlet from the
stormwater management BMP shall be a minimum of two and one-half inches
in diameter.
(f)
All detention and infiltration BMPs shall provide one foot of
freeboard between the design high water level 100-year water surface
elevation and the top of the basin.
(g)
Stabilized access 15 feet wide is to be provided to the stormwater
management BMPs to provide access capable of supporting maintenance
vehicles. The access way must be designed with a slope not to exceed
five horizontal to one vertical, 5H:1V.
(10)
Manufactured treatment devices may be used to meet the requirements of this section, 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 Atlantic 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 K(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 Atlantic 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 preconstruction groundwater recharge volume for the site; or
[2]
Demonstrate through hydrologic and hydraulic analysis that the
increase of stormwater runoff volume from preconstruction 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.
(e)
For all major developments in the Pinelands Protection Area of the Township, in addition to Subsection D(16)(b)[1] and [2] above, the total runoff volume generated from the net increase in impervious surfaces by a ten-year, twenty-four-hour storm shall be retained and infiltrated on-site.
(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 one-quarter 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.
|
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)3i, 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 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 post-construction
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 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.
(19)
In addition to all other requirements of this subsection, each
application for major development within the Pinelands Area, and any
other application where the Township otherwise requires a landscaping
plan within the Pinelands Area, shall contain a landscaping or revegetation
plan in accordance with the Pinelands CMP standards at N.J.A.C. 7:50-6.24(c).
(20)
Threatened and endangered species requirements. Stormwater management
measures shall avoid adverse impacts of the development on habits
for threatened and endangered species as documented in the Department's
Landscape Project or Natural Heritage Database established under N.J.S.A.
13:1B-15.147 through 13:1B-15.150, particular Helonias bullata (swamp
pink) and/or Clemmys muhlenbergi (bog turtle) and in accordance with
those standards stated in N.J.A.C. 7:8-5.2(c), N.J.A.C. 7:50-6.27,
and 7:50-6.33 and 7:50-6.34.
(21)
Exception and mitigation requirements. Exceptions from strict
compliance from the groundwater recharge, stormwater runoff quantity,
and stormwater runoff quality requirements established by this section
may be granted, at the discretion of the Township of Galloway, and
subject to approval by the Pinelands Commission for those projects
within the Pinelands Area, provided that all of the following conditions
are met:
(a)
The exception is consistent with that allowed by the Township
of Galloway.
(b)
The Township of Galloway has an adopted and effective municipal
stormwater management plan in accordance with N.J.A.C. 7:8-4.4, which
includes a mitigation plan in accordance with N.J.A.C. 7:8-4.2(c)11,
and is also certified by the Pinelands Commission. The mitigation
plan shall identify what measures are necessary to offset the deficit
created by granting the exception and Galloway Township shall submit
a written report to the county review agency and the NJDEP describing
the exception and the required mitigation. Guidance for developing
municipal stormwater management plans, including mitigation plans,
is available from the NJDEP, Division of Watershed Management, and
the New Jersey BMP Manual.
(c)
The applicant demonstrates that mitigation, in addition to the requirements of the mitigation plan discussed in Subsection D(21)(b) above, will be provided consistent with one of the following options:
[1]
Mitigation may be provided off site, but within the same drainage
areas as the development site, and shall meet or exceed the equivalent
recharge, quality or quantity performance standard which is lacking
on the development site due to the exception; or
[2]
In lieu of the required mitigation, a monetary "in-lieu contribution"
may be provided by the applicant to the Township of Galloway in accordance
with the following:
[a]
The amount of the in-lieu contribution shall be
determined by the Township of Galloway, but the maximum in-lieu contribution
required shall be equivalent to the cost of implementing and maintaining
the stormwater management measure(s) for which the exception is granted.
[b]
The in-lieu contribution shall be used to fund an off-site stormwater control mitigation project(s) located within the Pinelands Area, within the same drainage area as the development site, and shall meet or exceed the equivalent recharge, quality or quantity performance standards which are lacking on the development site. Such mitigation project shall be identified by the Township of Galloway in the Township of Galloway's adopted municipal stormwater management plan. The stormwater control project to which the monetary contribution will be applied shall be identified by the Township of Galloway at the time the exception is granted. The applicant shall amend the project description and site plan required in Subsection K to incorporate a description of both the standards for which an on-site exemption is being granted and of the selected off-site mitigation project.
[c]
The Township of Galloway shall expend the in-lieu contribution to implement the selected off-site mitigation project within five years from the date that payment is received. Should the Township of Galloway fail to expend the in-lieu contribution within the required time frame, the mitigation option provided in Subsection D(21)(c)[2] of this section shall be void and the Township of Galloway shall be prohibited from collecting in-lieu contributions.
[d]
For projects in the Pinelands Area an exception from strict compliance granted in accordance with Subsection D(21) above shall not constitute a waiver of strict compliance from the requirements of the Pinelands Comprehensive Management Plan at N.J.A.C. 7:50. An applicant should contact the Pinelands Commission to determine whether a waiver of strict compliance is also required in accordance with N.J.A.C. 7:50, Subchapter 4, Part V.
(22)
The use of stormwater management strategies to meet the performance standards in Subsection D of this section is not required for major developmental creating less than one acre of disturbance. However, the following requirements shall be met:
(a)
Within the Pinelands Area, each application for major development
and any other applications where the Township of Galloway otherwise
requires a landscaping plan shall contain a landscaping or revegetation
plan prepared in accordance with the Pinelands CMP standards [N.J.A.C.
7:50-6.24(c)];
(b)
Each applicant shall demonstrate that, at a minimum, existing
trees and vegetation on the development site will be preserved and
protected according to the minimum standards established by provisions
of the Township of Galloway Land Use Ordinance, Zoning Ordinance,
or by conditions of zoning or variance approval; and
(c)
Existing trees and vegetation shall be protected during construction
activities in accordance with the Standard for Tree Protection During
Construction provided in the NJ State Soil Conservation Committee
Standards for Soil Erosion and Sediment Control in New Jersey, which
is incorporated herein by reference as amended and supplemented.
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 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 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 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,
or at New Jersey Geological and Water Survey, 29 Arctic Parkway, PO
Box 420 Mail Code 29-01, Trenton, New Jersey 08625-0420.
F.
Soils investigation requirements.
(1)
Methods for assessing soil suitability for infiltration stormwater
management BMPs. The results of a subsurface investigation shall serve
as the basis for the site selection and design of stormwater infiltration
BMPs. The subsurface investigation shall include, but not be limited
to, a series of soil test pits and soil permeability tests conducted
in accordance with the following:
(a)
All soil test pits and soil permeability results shall be performed
under the direct supervision of a professional engineer. All soil
logs and permeability test data shall be accompanied by a certification
by a professional engineer. The results and location (horizontal and
vertical) of all soil test pits and soil permeability tests, both
passing and failing, shall be reported to the Township of Galloway.
(b)
A note indicating the following should be included on any plans where unsuitable soils have been encountered during the completion of test pits as required in Subsection F. Test pits shall be completed and witnessed by the Township Engineer, at the bottom of all proposed stormwater management facilities, at the time of construction.
(c)
During all subsurface investigations and soil test procedures,
adequate safety measures shall be taken to prohibit unauthorized access
to the excavations at all times. It is the responsibility of persons
performing or witnessing subsurface investigations and soil permeability
tests to comply with all applicable federal, state, and local laws
and regulations governing occupational safety.
(d)
A minimum of two soil test pits shall be excavated within the
footprint of any proposed infiltration BMP to determine the suitability
and distribution of soil types present at the site. Placement of the
test pits shall be within 20 feet of the basin perimeter, located
along the longest axis bisecting the BMP. For BMPs larger than 10,000
square feet in area, a minimum of one additional soil test pit shall
be conducted within each additional area of 10,000 square feet. The
additional test pit(s) shall be placed approximately equidistant to
other test pit(s), so as to provide adequate characterization of the
subsurface material. In all cases, where soil and/or groundwater properties
vary significantly, additional test pits shall be excavated in order
to accurately characterize the subsurface conditions below the proposed
infiltration BMP. Soil test pits shall extend to a minimum depth of
eight feet below the lowest elevation of the basin bottom or to a
depth that is at least two times the maximum potential water depth
in the proposed infiltration BMP, whichever is greater.
(e)
A soil test pit log shall be prepared for each soil test pit.
The test pit log shall, at a minimum, provide the elevation of the
existing ground surface, the depth and thickness (in inches) of each
soil horizon or substratum, the dominant matrix or background and
mottle colors using the Munsell System of classification for hue,
value and chroma, the appropriate textural class as shown on the USDA
textural triangle, the volume percentage of coarse fragments (larger
than two millimeters in diameter), the abundance, size, and contrast
of mottles, the soil structure, soil consistency, and soil moisture
condition, using standard USDA classification terminology for each
of these soil properties. Soil test pit logs shall identify the presence
of any soils horizon, substratum or other feature that exhibits an
in-place permeability rate less than one inch per hour.
(f)
Each soil test pit log shall report the depth to seasonally
high water level, either perched or regional, and the static water
level based upon the presence of soil mottles or other redoximophic
features including soil mottles resulting from soil saturation are
present, they shall be interpreted to represent the depth to the seasonal
high water table unless soil saturation or seepage is observed at
a higher level. When the determination of the seasonally high water
table shall be made in ground previously disturbed by excavation,
direct observation of the static water table during the months of
January through April shall be the only method of permitted.
(g)
Any soil horizon or substratum which exists immediately below
a perched zone of saturation shall be deemed by rule to exhibit unacceptable
permeability (less than one inch per hour). The perched zone of saturation
may be observed directly, inferred based upon soil morphology, or
confirmed by performance of a hydraulic head test as defined at N.J.A.C.
7:9A-5.9.
(h)
Stormwater infiltration BMPs shall not be installed in soils
that exhibit artesian groundwater conditions. A permeability test
shall be conducted in all soils that immediately underlie a perched
zone of saturation. Any zone of saturation which is present below
a soil horizon which exhibits an in-place permeability of less than
0.2 inch per hour shall be considered an artesian zone of saturation
unless a minimum one-foot-thick zone of unsaturated soil, free of
mottling or other redoximorphic features and possessing a chroma of
four or higher, exists immediately below the unsuitable soil.
(i)
After all construction activities have been completed on the
development site and the finished grade has been established in the
infiltration BMP, a minimum of one permeability test shall be conducted
within the most hydraulically restrictive soil horizon or substratum
below the as-built BMP to ensure the performance of the infiltration
BMP is as designed. Hand tools and manual permeability test procedures
shall be used for the purpose of confirming BMP performance. In addition,
the infiltration BMP shall be flooded with water sufficient to demonstrate
the performance of the BMP. Test results shall be certified to the
Township Engineer.
(2)
Percolation/permeability testing requirements.
(a)
A minimum of one permeability test shall be performed at each
soil test pit location. The soil permeability rate shall be determined
using test methodology as prescribed in N.J.A.C. 7:9A-6.2 (tube permeameter
test), 7:9A-6.5 (pit bailing test), or 7:9A-6.6 (Piezometer test).
When the tube permeameter test is used, a minimum of two replicate
samples shall be taken and tested. Alternative permeability test procedures
may be accepted by the approving authority, provided the test procedure
attains saturation of surrounding solid, accounts for hydraulic head
effects on infiltration rates, provides a permeability rate with units
expressed in inches per hour and is accompanied by a published source
reference. Examples of suitable sources include hydrogeology, geotechnical
or engineering text and design manuals, proceedings of American Society
for Testing and Materials (ASTM) symposia, or peer-review journals.
Neither a soil permeability class rating test, as described in N.J.A.C.
7:9A-6.3, nor a percolation test, as described in N.J.A.C. 7:9A-6.4,
are acceptable tests for establishing permeability values for the
purpose of complying with this section.
(b)
Soil permeability tests shall be conducted on the most hydraulically
restrictive horizon or substratum to be left in place below the basin
as follows. Where no soil replacement is proposed, the permeability
tests shall be conducted on the most hydraulically restrictive horizon
or substratum within four feet of the lowest elevation of the basin
bottom or to a depth equal to two times the maximum potential water
depth within the basin, whichever is greater. Where soil replacement
is proposed, the permeability tests shall be conducted within the
soil immediately below the depth of proposed soil replacement or within
the most hydraulically restrictive horizon or substratum to a depth
equal to two times the maximum potential water depth within the basin,
whichever is greater. Permeability tests may be performed on the most
hydraulically restrictive soil horizons or substrata at depths greater
than those identified above based upon the discretion of the design
or testing engineer. The tested infiltration rate should then be divided
by two to establish the soil's design permeability rate. Such division
will provide a 100% safety factor to the tested rate.
(c)
The minimum acceptable tested permeability rate of any existing
soil horizon or substratum shall be one inch per hour. Soil materials
that exhibit tested permeability rates slower than one inch per hour
shall be considered unsuitable for stormwater infiltration. The maximum
reportable tested permeability rate of any soil horizon or substratum
shall be no greater than 20 inches per hour regardless of the rate
attained in the test procedure.
(3)
Soil replacement material requirements. Material to replace unsuitable
soil located beneath stormwater facilities shall have a percolation/permeability
rate equal to or greater than six inches per hour, and a maximum of
20 inches per hour for projects located in the Pinelands section of
the Township. All material shall meet or exceed the quality of the
existing soil and shall be free of clay, muck, organic material, debris,
recycled pavement, recycled concrete or other material determined
to be unsuitable by the Township Engineer.

permanent installation of ladders, steps, rungs, or other features
that provide easily accessible means of egress from stormwater management
basins. Stormwater management basins shall include escape provisions
as follows:
[1]
If a stormwater management basin has an outlet structure, escape provisions shall be incorporated in or on the structure. With the prior approval of the reviewing agency identified in Subsection I(4), freestanding outlet structure may be exempted from this requirement.
[2]
Safety ledges shall be constructed on the slopes of all new stormwater management basins having a permanent pool of water deeper than 2 1/2 feet below the permanent water surface, and the second step shall be located one foot to 1 1/2 feet above the permanent water surface. See Subsection I(5) for an illustration of safety ledges in a stormwater management basin.
[3]
In new stormwater management basins, the maximum interior slope
for an earthen dam, embankment, or berm shall not be steeper than
three horizontal to one vertical.
(4)
Variance or exemption from safety standards. A variance or exemption
from the safety standards for stormwater management basins may be
granted only upon a written finding by the appropriate reviewing agency
that the variance or exemption will not constitute a threat to public
safety.

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.
(d)
Responsibility for inspection, maintenance and repair plan 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.
(e)
If the person responsible for maintenance identified under Subsection K(2) of this section is not a public agency, the inspection, maintenance and repair plan and any future revisions based on Subsection K(2)(g) of this section shall be recorded upon the deed of record for each property on which the inspection, maintenance and repair plan described in the maintenance plan must be undertaken.
(f)
Preventative and corrective maintenance shall be performed to
maintain the function of the stormwater management measure, including
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

In the event the person responsible fails to submit the inspection, maintenance and repair information to the Township of Galloway, notice shall be provided of the deficiency and the person responsible shall have 14 days to submit the required information. Galloway of Township, at its discretions, may extend the time allowed for submitting the required information. If the person responsible fails or refuses to complete the submission, Galloway Township may immediately proceed with the inspection of the stormwater management facilities. The costs and expenses of the inspection shall be billed against the stormwater management fund to be established for the inspection and review of the stormwater management facilities as established in Subsection K(2)(o)[1], Table A, provided at the end of this chapter.
[5]
The person responsible for inspection, maintenance and repair identified under Subsection K(2)(a) above shall make the site available for inspection by a representative of the Township of Galloway every two years. The costs and expenses of the inspection shall be billed against the stormwater management fund to be established for the inspection and review of the stormwater management facilities as established in Subsection K(2)(o)[2], Table A or Table B, as applicable.
(i)
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 the inspection, maintenance and repair
plan 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 the inspection, maintenance
and repair plan for good cause. If the responsible person fails or
refuses to perform such the inspection, maintenance and repair plan,
the municipality or county may immediately proceed to do so and shall
bill the cost thereof to the responsible person. Nonpayment of such
bill may result in a lien on the property.
(j)
Prior to the granting of any site development approval, the
applicant shall enter into an agreement (declaration of covenants
and restrictions for drainage structures) with Galloway Township to
ensure the continued operation and maintenance of the stormwater facility,
unless Galloway Township has consented to accept the facility as municipal.
This agreement shall be in a form satisfactory to the Township Attorney
and may include, but may not necessarily be limited to, personal guarantees,
deed restrictions, covenants and bonds. In cases where the property
is subdivided and sold separately, a homeowners' association or similar
permanent entity shall be established as the responsible entity, absent
an agreement by a governmental agency to assume responsibility. The
agreement shall also provide for regular inspection at the expense
of the applicant, or the applicant's successors in interest, and for
the undertaking by the applicant and successors of such corrective
measures as are shown by such inspection to be required for the proper
functioning of the facilities. The agreement shall require the applicant
to provide a twenty-year maintenance guarantee and a maintenance and
inspection program for the entire stormwater management system. The
maintenance guarantee and maintenance and inspection program shall
commence at the conclusion of the period required for the site's performance
guarantee as required by the Board. The inspection and maintenance
program shall identify the entity charged with responsibility for
the annual inspections and the completion of any necessary maintenance,
and the method to finance the program.
(k)
The applicant must obtain approval from the Township Engineer for all arrangements and values described in Subsection K(2)(j).
(l)
The applicant must deliver an easement for a clear and stabilized
accessway of 15 feet to all stormwater facilities for the purpose
of assuring vehicular access for maintenance activities.
(m)
The applicant must submit escrows and guarantees as required in Article IX, § 233-65A(2), of the Galloway Land Management Code.
(n)
Requirements for inspection, maintenance and repair of stormwater
BMPs that rely on infiltration. If a stormwater infiltration BMP is
incorporated into the design of a major development, the applicant
shall include the following requirements in its inspection, maintenance
and repair plan:
[1]
Once per month (if needed or if directed by Township Stormwater
Coordinator): mow side slopes, remove litter and debris, stabilize
eroded banks, and repair erosion at inflow structures;
[2]
After every storm exceeding one inch of rainfall: ensure that
infiltration BMPs drain completely within 72 hours after the storm
event. If stored water fails to infiltrate 72 hours after the end
of the storm, corrective measures shall be taken. Raking or tilling
by light equipment can assist in maintaining infiltration capacity
and break up clogged surfaces;
[3]
Four times per year (quarterly): inspect stormwater infiltration
BMPs for clogging and excessive debris and sediment accumulation within
the BMP, remove sediment (if needed) when completely dry;
[4]
Two times per year: inspect for signs of damage to structures,
repair eroded areas, check for signs of petroleum contamination and
remediate;
[5]
Once per year: inspect BMPs for unwanted tree growth and remove
if necessary, disc or otherwise aerate bottom of infiltrations basin
to a minimum depth of six inches; and
[6]
After every storm exceeding one inch of rainfall: inspect and,
if necessary, remove and replace K5 sand layer and accumulated sediment,
to restore the infiltration rate.
[7]
Additional guidance for the inspection, maintenance and repair
of stormwater infiltration BMPs can be found in the NJ BMP Manual.
(o)
Financing of inspection, maintenance and repair of stormwater
BMPs. An adequate means of ensuring permanent financing of the inspection,
maintenance and repair of stormwater BMPs shall be implemented and
detailed in the inspection, maintenance and repair plan. Permanent
financing of the inspection, maintenance and repair of stormwater
BMPs shall be accomplished by:
[1]
For nonmunicipal owned stormwater management facilities, the
assumption of the inspection and maintenance program by an entity
other than Galloway Township (i.e., county, public utility, homeowners'
association or individual) shall require the payment of fees to the
municipal stormwater management fund as calculated by Table A, provided
at the end of this chapter.
[2]
For stormwater management facilities owned by the Township of
Galloway, the assumption of the inspection and maintenance program
by Galloway Township shall require the payment of fees to a municipal
stormwater fund in an amount equivalent to the cost of both ongoing
maintenance activities and necessary structural replacements as calculated
by Table B, provided at the end of this chapter
(3)
Nothing in this section shall preclude the municipality in which
the major development is located from requiring the posting or a performance
or maintenance guarantee in accordance with N.J.S.A. 40:55D-53.
L.
As-built certification. When excavated and completed, the design
engineer shall certify, in writing, to the Township that the stormwater
facility will operate as intended in the design phase taking into
consideration all soil and water conditions encountered during construction.
As-built percolation test results shall also be provided if the basin
has been used as a place for sediment accumulation during the construction
process.
M.
After all construction activities and required field testing have
been completed on the development site, as-built plans depicting design
and as-built elevations of all stormwater management measures shall
be prepared by a licensed land surveyor and submitted to the Township
Engineer. Based upon the Township Engineer's review of the as-built
plans, all corrections or remedial actions deemed by the Township
Engineer to be necessary due to the failure to comply with the standards
established by this section and/or any reasons of public health or
safety shall be completed by the applicant. In lieu of review by the
Township Engineer, the Township of Galloway reserves the right to
engage a professional engineer to review the as-built plans. The applicant
shall pay all costs associates with such review.
N.
Penalties. Any person who erects, constructs, alters, repair, converts, maintains, or uses any building, structure or land in violation of this section shall be subject to the penalties as stated in § 233-64.
(1)
Each instance of engaging in a separate regulated activity in violation
of this section shall be deemed a separate offense.
(2)
In addition, the Borough may institute civil action for injunctive
or other relief to enforce the provisions of this section.
(3)
This section shall be enforced by the Construction Official, or his
designees, the Department of Public Utilities and/or the Code Enforcement
Department.

A.
Scope and purpose.
(1)
Policy statement. Flood control, groundwater recharge, erosion
control and pollutant reduction shall be achieved using stormwater
management measures, including green infrastructure best management
practices (BMPs) and nonstructural stormwater management strategies.
Green infrastructure BMPs and low-impact development 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. Green infrastructure BMPs and low-impact
development 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 contained in this section.
(2)
Purpose. The purpose of this section is to establish, within
the Pinelands Area portion of Galloway Township, minimum stormwater
management requirements and controls as authorized by the Pinelands
Protection Act (N.J.S.A. 13:18A-1 et seq.) and consistent with the
Pinelands Comprehensive Management Plan (CMP) (N.J.A.C. 7:50-1.1 et
seq.) and the New Jersey Department of Environmental Protection (NJDEP)
Stormwater Management Regulations (N.J.A.C. 7:8-1.1 et seq.). The
standards in this section are intended to minimize the adverse impact
of stormwater runoff on water quality and water quantity, to facilitate
groundwater recharge, and to control and minimize soil erosion, stream
channel erosion, sedimentation and pollution associated with stormwater
runoff. Moreover, Pinelands Area resources are to be protected in
accordance with the antidegradation policies contained in the New
Jersey Surface Water Quality Standards (N.J.A.C. 7:9B-1.1 et seq.).
Additionally, this section is intended to ensure the adequacy of existing
and proposed culverts and bridges and to protect public safety through
the proper design and operation of stormwater BMPs. If there are any
conflicts between a provision required by the Pinelands CMP and a
provision required by the NJDEP, the Pinelands CMP provision shall
apply.
(3)
Applicability.
(a)
The terms "development," "major development" and "minor development" are defined in § 233-55.1B in accordance with the Pinelands CMP (N.J.A.C. 7:50-2.11) and differ from the definitions of "development" and "major development" contained in the NJDEP Stormwater Management Regulations (N.J.A.C. 7:8-1.2).
(b)
This section shall apply within the Pinelands Area to all major
development, and to minor development meeting the following criteria:
[1]
Development involving the construction of four
or fewer dwelling units;
[2]
Development involving any nonresidential use and
resulting in an increase of greater than 1,000 square feet of regulated
motor vehicle surfaces; and
[3]
Development involving the grading, clearing, or
disturbance of an area in excess of 5,000 square feet within any five-year
period. For development meeting this criterion, the stormwater management
standards for major development set forth in this section shall apply.
(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.
(c)
In the event that a regional stormwater management plan(s) is
prepared and formally adopted pursuant to N.J.A.C. 7:8-1.1 et seq.
for any drainage area(s) or watershed(s) of which Galloway Township
is a part, the stormwater provisions of such a plan(s) shall be adopted
by Galloway Township within one year of the adoption of a Regional
Stormwater Management Plan (RSWMP) as an amendment to an Areawide
Water Quality Management Plan. Local ordinances proposed to implement
the RSWMP shall be submitted to the Pinelands Commission for certification
within six months of the adoption of the RSWMP per N.J.A.C. 7:8 and
the Pinelands CMP.

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 NJDEP and the Pinelands Commission in accordance with § 233-55.1E(2). Alternative stormwater management measures may be used to satisfy the requirements at § 233-55.1C(14) only if the measures meet the definition of green infrastructure at § 233-55.1B. Alternative stormwater management measures that function in a similar manner to a BMP listed at § 233-55.1C(14)(b) are subject to the contributory drainage area limitation specified at § 233-55.1C(14)(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 § 233-55.1C(14)(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 § 233-55.1J is granted from § 233-55.1C(14).
(7)
Hydraulic impacts.
(a)
For all major development, groundwater mounding analysis shall
be required for purposes of assessing the hydraulic impacts of mounding
of the water table resulting from infiltration of stormwater runoff
from the maximum storm designed for infiltration. The mounding analysis
shall provide details and supporting documentation on the methodology
used. Groundwater mounds shall not cause stormwater or groundwater
to break out to the land surface or cause adverse impacts to adjacent
water bodies, wetlands, or subsurface structures, including, but not
limited to, basements and septic systems. Where the mounding analysis
identifies adverse impacts, the stormwater management measure shall
be redesigned or relocated, as appropriate.
(b)
For all applicable minor development, a design engineer's
certification that each green infrastructure stormwater management
measure will not adversely impact basements or septic systems of the
proposed development shall be required.
(8)
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; wetland transition areas;
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 designed to infiltrate stormwater
shall be designed, constructed, and maintained to provide a minimum
separation of at least two feet between the elevation of the lowest
point of infiltration and the seasonal high water table;
(c)
Stormwater management measures designed to infiltrate stormwater
shall be sited in suitable soils verified by testing to have permeability
rates between one and 20 inches per hour. A factor of safety of two
shall be applied to the soil's permeability rate in determining
the infiltration measure's design permeability rate. If such
soils do not exist on the parcel proposed for development or if it
is demonstrated that it is not practical for engineering, environmental,
or safety reasons to site the stormwater infiltration measure(s) in
such soils, the stormwater infiltration measure(s) may be sited in
soils verified by testing to have permeability rates in excess of
20 inches per hour, provided that stormwater is routed through a bioretention
system prior to infiltration. Said bioretention system shall be designed,
installed, and maintained in accordance with the New Jersey Stormwater
BMP Manual;
(d)
The use of stormwater management measures that are smaller in
size and distributed spatially throughout a parcel, rather than the
use of a single, larger stormwater management measure shall be required;
(e)
Methods of treating stormwater prior to entering any stormwater
management measure shall be incorporated into the design of the stormwater
management measure to the maximum extent practical;
(f)
To avoid sedimentation that may result in clogging and reduction
of infiltration capability and to maintain maximum soil infiltration
capacity, the construction of stormwater management measures that
rely upon infiltration shall be managed in accordance with the following
standards:
[1]
No stormwater management measure shall be placed
into operation until its drainage area has been completely stabilized.
Instead, upstream runoff shall be diverted around the measure and
into separate, temporary stormwater management facilities and sediment
basins. Such temporary facilities and basins shall be installed and
utilized for stormwater management and sediment control until stabilization
is achieved in accordance with N.J.A.C. 2:90;
[2]
If, for engineering, environmental, or safety reasons, temporary stormwater management facilities and sediment basins cannot be constructed on the parcel in accordance with Subsection C(8)(f)[1] above, the stormwater management measure may be placed into operation prior to the complete stabilization of its drainage area provided that the measure's bottom during this period is constructed at a depth at least two feet higher than its final design elevation. When the drainage area has been completely stabilized, all accumulated sediment shall be removed from the stormwater management measure, which shall then be excavated to its final design elevation; and
[3]
To avoid compacting the soils below a stormwater
management measure designed to infiltrate stormwater, no heavy equipment,
such as backhoes, dump trucks, or bulldozers shall be permitted to
operate within the footprint of the stormwater management measure.
All excavation required to construct a stormwater management measure
that relies on infiltration shall be performed by equipment placed
outside the footprint of the stormwater management measure. If this
is not possible, the soils within the excavated area shall be renovated
and tilled after construction is completed. Earthwork associated with
stormwater management measure construction, including excavation,
grading, cutting, or filling, shall not be performed when soil moisture
content is above the lower plastic limit;
(g)
Dry wells shall be designed to prevent access by amphibian and
reptiles;
(h)
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 established at § 233-55.1C(16)(d). 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 § 233-55.1G(3)(a);
(i)
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;
(j)
Stormwater management BMPs shall be designed to meet the minimum safety standards for stormwater management BMPs at § 233-55.1G; and
(k)
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.
(l)
All detention and infiltration BMPs shall provide one foot of
freeboard between the design high water level 100-year water surface
elevation and the top of the basin.
(m)
Stabilized access 15 feet wide is to be provided to the stormwater
management BMPs to provide access capable of supporting maintenance
vehicles. The accessway must be designed with a slope not to exceed
five horizontal to one vertical, 5H:1V.
(9)
Manufactured treatment devices may be used to meet the requirements of this section, provided the pollutant removal rates are verified by the New Jersey Corporation for Advanced Technology and certified by the NJDEP. Manufactured treatment devices that do not meet the definition of green infrastructure at § 233-55.1B may be used only under the circumstances described at § 233-55.1C(14)(d).
(10)
Any application for a new agricultural development that meets the definition of major development at N.J.A.C. 7:8-1.2 shall be submitted to the Soil Conservation District for review and approval in accordance with the requirements at § 233-55.1C(14), (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.
(11)
If there is more than one drainage area, the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at § 233-55.1C(15), (16), and (17) 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.
(12)
Any stormwater management measure authorized under the municipal stormwater management plan or this section shall be reflected in a deed notice recorded in the Atlantic County Clerk's Office. 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 § 233-55.1C(14), (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 § 233-55.1I(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.
(13)
A stormwater management measure approved under the municipal stormwater management plan or this section 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 contained in § 233-55.1C(15), (16), and (17) 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 Atlantic County Clerk's Office and shall contain a description and location of the stormwater management measure, as well as reference to the maintenance plan, in accordance with Subsection C(12) 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 C(12) above.
(14)

(d)
If a variance in accordance with § 233-55.1J is granted from the requirements of this subsection, then BMPs from Table 1, 2, or 3 at § 233-55.1C(5) and/or an alternative stormwater management measure approved in accordance with § 233-55.1C(6) may be used to meet the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at § 233-55.1C(15), (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 § 233-55.1C(15), (16), and (17).
(15)
Groundwater recharge standards.
(a)
This subsection contains the minimum design and performance
standards for groundwater recharge as follows:
(b)
For all major development, the total runoff volume generated
from the net increase in impervious surfaces by a ten-year, twenty-four-hour
storm shall be retained and infiltrated onsite.
(c)
For minor development that involves the construction of four
or fewer dwelling units, the runoff generated from the total roof
area of the dwelling(s) by a ten-year, twenty-four-hour storm shall
be retained and infiltrated through installation of one or more green
infrastructure stormwater management measures designed in accordance
with the New Jersey Stormwater BMP Manual. Appropriate green infrastructure
stormwater management measures include, but are not limited to dry
wells, pervious pavement systems, and small scale bioretention systems,
including rain gardens.
(d)
For minor development that involves any nonresidential use and
will result in an increase of greater than 1,000 square feet of regulated
motor vehicle surfaces, the water quality design storm volume generated
from these surfaces shall be recharged onsite.
(e)
Stormwater from areas of high pollutant loading and/or industrial stormwater exposed to source material shall only be recharged in accordance with § 233-55.1C(16)(h).
(16)
Stormwater runoff quality standards.
(a)
This subsection contains the minimum design and performance
standards to control stormwater runoff quality impacts of:
[1]
Major development;
[2]
Minor development that involves any nonresidential
use and will result in an increase of greater than 1,000 square feet
of regulated motor vehicle surfaces; and
[3]
Any development involving the grading, clearing,
or disturbance of an area in excess of 5,000 square feet within any
five-year period.
(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 established at § 233-55.1C(16)(d) 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 C(16)(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.

(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 established at § 233-55.1C(16)(d). 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 § 233- 55.1C(15), (16), and (17).
(g)
For all major development, stormwater management measures shall be designed to achieve a minimum of 65% reduction of the post-construction total nitrogen load from the developed site, including those permanent lawn or turf areas that are specifically intended for active human use as described at N.J.A.C. 7:50-6.24(c)3, in stormwater runoff generated from the water quality design storm established at § 233-55.1C(16)(d). In achieving a minimum 65% reduction of total nitrogen, the design of the site shall include green infrastructure in accordance with the New Jersey Stormwater BMP Manual and shall optimize nutrient removal. The minimum 65% total nitrogen reduction may be achieved by using a singular stormwater management measure or multiple stormwater management measures in series.
(h)
In high pollutant loading areas (HPLAs) and/or areas where stormwater runoff is exposed to source material, as defined in § 233-55.1B, the following additional water quality standards shall apply:
[1]
The areal extent and amount of precipitation falling
directly on or flowing over HPLAs and/or areas where stormwater is
exposed to source material shall be minimized through the use of roof
covers, canopies, curbing or other physical means to the maximum extent
practical in order to minimize the quantity of stormwater generated
from HPLA areas and areas where stormwater runoff is exposed to source
material;
[2]
The stormwater runoff originating from HPLAs and/or areas where stormwater runoff is exposed to source material shall be segregated and prohibited from commingle with stormwater runoff originating from the remainder of the parcel unless it is first routed through one or more stormwater management measures required at Subsection C(16)(h)[3] below;
[3]
The stormwater runoff from HPLAs and/or areas where stormwater runoff is exposed to source material shall incorporate stormwater management measures designed to reduce the post-construction load of TSS by at least 90% in stormwater runoff generated from the water quality design storm established at § 233-55.1C(16)(d) using one or more of the measures identified at Subsection C(16)(h)[3][a] or [b] below. In meeting this requirement, the minimum 90% removal of total suspended solids may be achieved by utilizing multiple stormwater management measures in series:
[a]
Any measure designed in accordance with the New
Jersey Stormwater BMP Manual to remove total suspended solids. Any
such measure must be constructed to ensure that the lowest point of
infiltration within the measure maintains a minimum of two feet of
vertical separation from the seasonal high-water table; and
[b]
Other measures certified by the NJDEP, including
a media filtration system manufactured treatment device with a minimum
80% removal of total suspended solids as verified by the New Jersey
Corporation for Advanced Technology; and
[4]
If the potential for contamination of stormwater runoff by petroleum products exists on-site, prior to being conveyed to the stormwater management measure required at Subsection C(16)(h)[3] above, the stormwater runoff from the HPLAs and areas where stormwater runoff is exposed to source material shall be conveyed through an oil/grease separator or other equivalent manufactured filtering device providing for the removal of petroleum hydrocarbons. The applicant shall provide the review agency with sufficient data to demonstrate acceptable performance of the device.
(i)
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.
(j)
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.
(17)
Stormwater runoff quantity standards.
(a)
This subsection contains the minimum design and performance
standards to control stormwater runoff quantity impacts related to
applicable major and minor development.
(b)
In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at § 233-55.1D, 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 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
post-construction 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 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 C(17)(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.
(d)
There shall be no direct discharge of stormwater runoff from
any point or nonpoint source to any wetland, wetlands transition area,
or surface water body. In addition, stormwater runoff shall not be
directed in such a way as to increase the volume and rate of discharge
into any wetlands, wetlands transition area, or surface water body
from that which existed prior to development of the parcel.
(e)
To the maximum extent practical, there shall be no direct discharge
of stormwater runoff onto farm fields to protect farm crops from damage
due to flooding, erosion, and long-term saturation of cultivated crops
and cropland.
(18)
As-built requirements for major development are as follows:
(a)
After all construction activities have been completed on the
parcel and finished grade has been established in each stormwater
management measure designed to infiltrate stormwater, replicate post-development
permeability tests shall be conducted to determine if as-built soil
permeability rates are consistent with design permeability rates.
The results of such tests shall be submitted to the municipal engineer
or other appropriate reviewing engineer. If the results of the post-development
permeability tests fail to achieve the minimum required design permeability
rate, utilizing a factor of safety of two, the stormwater management
measure shall be renovated and retested until the required permeability
rates are achieved; and
(b)
After all construction activities and required testing have
been completed on the parcel, as-built plans, including as-built elevations
of all stormwater management measures shall be submitted to the municipal
engineer or other appropriate reviewing engineer to serve as a document
of record. Based upon that engineer's review of the as-built
plans, all corrections or remedial actions deemed necessary due to
the failure to comply with design standards and/or for any reason
concerning public health or safety, shall be completed by the applicant.
In lieu of review by the municipal engineer, the municipality may
engage a licensed professional engineer to review the as-built plans
and charge the applicant for all costs associated with such review.
D.
Calculation of stormwater runoff and groundwater recharge.
(1)
Stormwater runoff shall be calculated by the design engineer
using 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, except that the Rational Method for peak flow and
the Modified Rational Method for hydrograph computations shall not
be used. 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.
(2)
In calculating stormwater runoff using the NRCS methodology,
the appropriate twenty-four-hour rainfall depths as developed for
the parcel by the National Oceanic and Atmospheric Administration,
https://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html?bkmrk=nj, shall
be utilized.
(3)
For the purpose of calculating runoff coefficients and groundwater
recharge, there is a presumption that the preconstruction condition
of a site or portion thereof is a wooded land use with good hydrologic
condition. 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. 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).
(4)
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.
(5)
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.
(6)
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.
(7)
Groundwater recharge may be calculated in accordance with 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
or at New Jersey Geological and Water Survey, 29 Arctic Parkway, PO
Box 420 Mail Code 29-01, Trenton, New Jersey 08625-0420.

is subdivided and sold separately, a homeowners' association
or similar permanent entity shall be established as the responsible
entity, absent an agreement by a governmental agency to assume responsibility.
The agreement shall also provide for regular inspection at the expense
of the applicant, or the applicant's successor in interest, and
for the undertaking by the applicant and successors of such corrective
measures as are shown by such inspection to be required for the property
functioning of the facilities. The agreement shall require the applicant
to provide a twenty-year maintenance guarantee and a maintenance and
inspection program for the entire stormwater management system. The
maintenance guarantee and maintenance and inspection program shall
commence at the conclusion of the period required for the site's
performance guarantee as required by the Board. The inspection and
maintenance program shall identify the entity charged with the responsibility
for the annual inactions and the completion of any necessary maintenance,

shall include the following requirements in its inspection, maintenance
and repair plan:
[1]
Once per month (if needed or if directed by Township
Stormwater Coordinator): mow side slopes, remove litter and debris,
stabilize eroded banks, and repair erosion at inflow structures;
[2]
After every storm exceeding one inch of rainfall:
ensure that infiltration BMPs drain completely within 72 hours after
the storm event. If stored water fails to infiltrate 72 hours after
the end of the storm, corrective measures shall be taken. Raking or
tilling by light equipment can assist in maintaining infiltration
capacity and break up clogged surfaces;
[3]
Four times per year (quarterly): inspect stormwater
infiltration BMPs for clogging and excessive debris and sediment accumulation
within the BMP, remove sediment (if needed) when completely dry;
[4]
Two times per year: inspect for signs of damage
to structures, repair eroded areas, check for signs of petroleum contamination
and remediate;
[5]
Once per year: inspect BMPs for unwanted tree growth
and remove if necessary, disc or otherwise aerate bottom of infiltrations
basin to a minimum depth of six inches; and
[6]
After every storm exceeding one inch of rainfall:
inspect and, if necessary, remove and replace K5 sand layer and accumulated
sediment, to restore the infiltration rate.
[7]
Additional guidance for the inspection, maintenance
and repair of stormwater infiltration BMPs can be found in the NJ
BMP Manual.
(4)
Nothing in this section shall preclude the municipality in which
the major development is located from requiring the posting of a performance
or maintenance guarantee in accordance with N.J.S.A. 40:55D-53.

For the purposes of this analysis, technical impracticability exists
only when the design and performance standard cannot be met for engineering,
environmental, or safety reasons. A municipality's approval of
a variance shall apply to an individual drainage area and design and
performance standard and shall not apply to an entire site or project,
unless an applicant provides the required analysis for each drainage
area within the site and each design and performance standard;
(d)
The applicant demonstrates that the proposed design achieves
the maximum possible compliance with the design and performance standards
of this section on-site; and
(e)
A mitigation project is implemented, in accordance with the
following:
[1]
All mitigation projects shall be located in the
Pinelands Area and in the same HUC-14 as the parcel proposed for development.
If the applicant demonstrates that no such mitigation project is available,
the municipality may approve a variance that provides for mitigation
within the same HUC-11 as the parcel proposed for development, provided
the mitigation project is located in the Pinelands Area.
[2]
The proposed mitigation project shall be consistent with the municipal stormwater management plan certified by the Pinelands Commission. If said stormwater management plan does not identify appropriate parcels or projects where mitigation may occur, the applicant may propose a mitigation project that meets the criteria in Subsection J(2)(e)[1] above.
[3]
The mitigation project shall be approved no later
than preliminary or final site plan approval of the major development.
[4]
The mitigation project shall be constructed prior
to, or concurrently with, the development receiving the variance.
[5]
The mitigation project shall comply with the green infrastructure standards at Subsection C(14).
[6]
If the variance that resulted in the mitigation project being required is from the green infrastructure standards at § 233-55.1C(14), then the mitigation project must use green infrastructure BMPs in Table 1 contained at § 233-55.1C(5), and/or an alternative stormwater management measure approved in accordance with § 233-55.1C(6) that meets the definition of green infrastructure to manage an equivalent or greater area of impervious surface and an equivalent or greater area of motor vehicle surface as the area of the major development subject to the variance. Grass swales and vegetative filter strips may only be used in the mitigation project if the proposed project additionally includes a green infrastructure BMP other than a grass swale or vegetative filter strip. The green infrastructure used in the mitigation project must be sized to manage the water quality design storm established at § 233-55.1C(16)(d), at a minimum, and is subject to the applicable contributory drainage area limitation specified at § 233-55.1C(14)(b), as applicable.
[7]
A variance from the groundwater recharge standards at § 233-55.1C(15) may be granted provided that the total volume of stormwater infiltrated by the mitigation project equals or exceeds the volume required at § 233-55.1C(15).
[8]
A variance from the stormwater runoff quality standards at § 233-55.1C(16) may be granted if the following are met:
[a]
The total drainage area of motor vehicle surface
managed by the mitigation project(s) must equal or exceed the drainage
area of the area of the major development subject to the variance
and must provide sufficient TSS removal to equal or exceed the deficit
resulting from granting the variance for the major development; and
[b]
The mitigation project must remove nutrients to the maximum extent feasible in accordance with § 233-55.1C(16)(g).
[9]
A variance from the stormwater runoff quantity standards at § 233-55.1C(17) may be granted if the following are met:
[a]
The applicant demonstrates, through hydrologic
and hydraulic analysis, including the effects of the mitigation project,
that the variance will not result in increased flooding damage below
each point of discharge of the major development;
[b]
The mitigation project indirectly discharges to
the same watercourse and is located upstream of the major development
subject to the variance; and
[c]
The mitigation project provides peak flow rate attenuation in accordance with § 233-55.1C(17)(b)[3] for an equivalent or greater area than the area of the major development subject to the variance. For the purposes of this demonstration, equivalent includes both size of the area and percentage of impervious surface and/or motor vehicle surface.
[10]
The applicant or the entity assuming maintenance responsibility for the associated major development shall be responsible for preventive and corrective maintenance (including replacement) of the mitigation project and shall be identified as such in the maintenance plan established in accordance with § 233-55.1I. This responsibility is not transferable to any entity other than a public agency, in which case a written agreement with that public agency must be submitted to the review agency.
(3)
Any approved variance shall be submitted by the municipal review
agency to the county review agency and the NJDEP, by way of a written
report describing the variance, as well as the required mitigation,
within 30 days of the approval.
K.
Penalties. Any person(s) who erects, constructs, alters, repairs, converts, maintains, or uses any building, structure or land in violation of this section shall be subject to the penalties as stated in § 233-64.
(1)
Each instance of engaging in a separate regulated activity in
violation of this section shall be deemed a separate offense.
(2)
In addition, the Township may institute a civil action for injunctive
or other relief to enforce the provisions of this section.
(3)
This section shall be enforced by the construction official,
or his designees, the Department of Public Works and/or the Code Enforcement
Department.
