Township of Galloway, NJ Improvement and Construction Standards

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]

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]

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.

Care shall be used to avoid damage to manholes, curbs, gutters and other existing structures or improvements in the roadways.

Deviation from minimum standards.

[Added 5-21-1979 by Ord. No. 584]

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.

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.

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.

Upon receipt of said information from the Municipal Engineer, the Code Enforcement Officer shall supply said information to the applicant.

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.

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.

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.

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.

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]

Application by one property owner.

[Added 9-2-1980 by Ord. No. 636]

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).

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:

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.

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.

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.

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.

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.

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.

Design of certain streets.

[Added 2-25-2003 by Ord. No. 1523; amended 11-28-2006 by Ord. No. 1669]

In addition to the standards set forth previously in this chapter, any applicant, developer, contractor or any other person must construct certain streets or sections of streets as designed or certified by the Municipal Engineer for the Township of Galloway and approved by the Planning Board for the Township of Galloway.

Designs are approved for the following streets or sections of streets. Plans are on file with the Clerk for the Township of Galloway.

Street	Limits	Plan Number
Damson Avenue	US Rt. 30 northerly to McKinley Avenue	GT02008-TR
Buchanan Avenue	Donna Drive easterly to Chris Gaupp Drive	GT01008
Chris Gaupp Drive	US Rt. 30 to Jimmie Leeds Road (CR561)	GT04176

§ 233-45 Parking areas.

Parking areas shall be constructed to meet the following requirements:

All parking spaces to be a minimum area of 180 square feet and a minimum of nine feet in width.

Pavement construction.

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]

Base material shall be a minimum of four inches of soil aggregate, Type 5, Class A.

In instances where parking is demonstrated to be of a temporary or occasional nature, this requirement may be waived by the Planning Board.

§ 233-46 Street signs.

Street signs of the type and design to be approved by the Planning Board shall be installed at all street intersections.

§ 233-47 Curbs and gutters.

[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.

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.

Installations on county roads shall meet county specifications.

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.

[Added 8-19-2014 by Ord. No. 1892]

§ 233-48 Streetlighting.

[Amended 7-5-1983 by Ord. No. 733]

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.

§ 233-49 Sidewalks.

[Amended 7-6-1982 by Ord. No. 700; 8-19-2014 by Ord. No. 1892]

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.

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.

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.

Sidewalks at the location are not necessary for public safety or otherwise to serve the public interest.

The public interest would be better served by the installation of sidewalks at another location.

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.

Sidewalk and Pedestrian Path Fund.

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.

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.

§ 233-50 Bikeways.

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.

§ 233-51 Shade trees.

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]

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.

§ 233-52 Tree removal and protection.

[Added 3-28-2000 by Ord. No. 1416; amended 8-28-2001 by Ord. No. 1482; 5-9-2006 by Ord. No. 1654]

Purpose.

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.

DIAMETER AT POINT OF MEASUREMENT

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.

Definitions. The following words and expressions as used in this section shall have the following meanings, unless the context clearly indicates a different meaning:

AGENCY

The Township of Galloway, any of its departments, including but not limited to the Planning or Zoning Board or its Engineer or Planner or a duly recognized representative of either entity.

CLEAR CUTTING

The removal of all standing trees on a lot or portion of a lot.

DEATH OF A TREE

As determined by an appropriately appointed Township official.

DEVELOPMENT

See § 233-4.

The diameter of a tree measured 4 1/2 feet (forestry method) above the ground level on the downhill side for existing trees. Trees utilized in the replacement of existing trees or proposed as part of a landscape plan shall be measured 12 inches above ground level for trees over a four-inch caliper; the measurement shall be six inches above grade for trees four-inch caliper (nursery method) or less. Diameter at point of measurement may appear as the abbreviation "DPM."

DRIP LINE

A limiting line established by a series of perpendicular drop points marking the maximum radius of the crown of an existing tree, but not less than six feet from the trunk, whichever is greater.

REPLACEMENT TREE

A nursery-grown tree, properly balled, marked with a durable label indicating genus, species, and variety, and satisfying the standards established for nursery stock and installation thereof, set forth by the American Nursery and Landscape Association.

SELECTIVE CUTTING

The removal of larger trees on an individual basis while leaving trees of lesser size.

SILT FENCE

A black plastic-impregnated fabric material typically available in two-foot-wide rolls.

SILT FENCING

The installation of silt fence material such that one side is firmly buried in the ground, and the two-foot width is vertically held by periodically spaced sturdy supports. The purpose of silt fencing is to contain soil and debris within a construction or storage zone.

SILVICULTURE

The management of any wooded tract of land to ensure its continued survival and welfare, whether for commercial or noncommercial purposes, pursuant to a plan approved by the New Jersey Bureau of Forestry.

SNOW FENCE MATERIAL

A brightly colored plastic fencing punctuated with large holes typically available in two- to three-foot-wide rolls.

SNOW FENCING

The installation of snow fence material vertically oriented around trees to be protected, and in front of tree canopies and other protected areas, so that construction equipment does not impact the protected areas.

SPECIMEN TREE

Any tree of DPM of 18 inches or greater unless specifically exempted by the provisions of this section.

THINNING

The removal of undesirable, competitive, diseased or damaged trees so as to cultivate and improve the development of remaining trees on the lot.

TREES

Any deciduous or coniferous species which reaches a typical height of 12 feet or more, and has a typical DPM of four inches or greater at maturity.

WOODED ACRES PERMITTED FOR DEVELOPMENT

The wooded lands within a lot or tract which are not specifically excluded by any federal, state, county or Township law or ordinance, deed restriction or covenant running with the land. For purposes of this section, those lands specifically eliminated from consideration as wooded acres permitted for development include, but are not limited 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

Restrictions.

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.

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.

Removal of trees; permit required.

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.

Individual lots not subject to a development application may be cleared in excess of the provisions of this section of the ordinance without a permit. However, any such excessive clearing of 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.

Exemptions. The following shall be exempt from the requirements of this section:

Commercial nurseries and fruit orchards.

Christmas tree farms.

Lots that are less than 20,000 square feet on which the owner or its contractor or other worker is removing not more than five trees, all with DPMs between eight inches and 12 inches, in any consecutive two-year period.

Removal of trees which have been previously determined by the Office of Township Engineer or Planner or personnel approved by the Office of Township Engineer or Planner to be:

Dead, dying or obviously diseased.

Trees which have suffered significant damage.

Any tree or trees whose angle or growth makes them a hazard to structures or human life.

Any tree growing on or over a public right-of-way or public land.

Pruning or removal of trees within the right-of-way by utility companies for maintenance of utility wires or pipelines and the pruning of trees within sight easements.

All lands within the AG (Agricultural Production District) as indicated on the official Galloway Township Zoning Map.

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.

Development projects for which applications have been deemed complete on or before the effective date of this section.

The following exemptions apply to single-family residential uses:

Where the location of an existing tree provides no other alternative but to place a structure outside the permitted building setbacks.

Where the location of an existing tree negatively impacts on an existing septic field.

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)

Tree removal/protection requirements for major and minor subdivisions and site plans.

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:

The boundary and acreage of the site and all block and lot numbers as shown on the Tax Map of the Township;

The location and identity of all trees of DPM of 12 inches or greater.

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;

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.

Specific proposals for replanting or replacements, if applicable;

The location of streams and water courses; and

The location of slopes with grades steeper than 15% from which trees are to be removed.

Areas noted where tree removal is necessary due to grade changes. Areas shall be shaded and noted accordingly.

Permit application procedure.

Application form. The application form shall be available from the Office of Township Engineer or Planner and/or Township Zoning Officer and shall include the following information:

Name and address of the applicant for the permit, status of legal entity (individual, partnership, corporation of this or any other state);

Status of the applicant with respect to land (owner, lessee, tenant, purchaser, under contract, etc.), and, if other than the owner of the property, an accompaniment providing the owner's written consent;

Address of the property (street and number) and block and lot number;

A list of all trees, deciduous or coniferous, to be removed with a DPM equal to or greater than 12 inches identified by size and species, including total number of each species to be removed;

Purpose for tree removal (construction, street or roadway, driveway, utility easement, recreation areas, patio, parking lot, etc.);

Such other information as may be deemed necessary in order effectively to process and decide such application; and

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.

Landscape plan.

The following information shall be provided on a landscape plan prepared in accordance with § 233-36E of this chapter:

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.

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.

Clear labeling of the entire area intended for tree removal/protection.

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.

The landscape plan is to accompany the submission of the application.

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.

Clearing requirements.

Design requirements.

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.

Existing tree canopy clearing.

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.

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.

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.

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.

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.

Site protection.

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.

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.

Chain link fence may be required for tree protection if warranted by site conditions and the relative rarity of the plant.

Snow fencing used for tree protection shall be firmly secured along the drip line, but not less than six feet from the trunk.

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.

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.

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.

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.

Inspections and approvals. Inspections after application submittals and approvals for clearing, for obtaining building permits, and for granting certificates of occupancy (COs), are as given in § 233-52L.

Tree care and plantings.

Tree replacement and reforestation.

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	0
	Greater than or equal to 8, but less than 12	2
	Greater than or equal to 12, but less than 18	4
	Greater than or equal to 18, but less than 24	6
	Greater than or equal to 24, but less than 30	8
	Greater than or equal to 30, but less than 36	10
	Greater than 36	12+*

	Note:
	* One additional tree for each inch of DPM over 36

Replacement tree(s) shall be located on site.

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.

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.

Pollution recovery. For every residential, commercial, or industrial site development, the plan shall include the addition of one tree for every four parking spaces.

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).

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).

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].

Residential lots (excluding major and minor subdivisions).

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.

Application form.

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.

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.

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.

Design requirement.

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.

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.

Section 233-52G(6) of this section shall be considered in the decision to permit the removal of any regulated trees.

Site protection. Site protection measures shall be provided in accordance with § 233-52F(3)(b).

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)

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.

Tree replacement.

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.

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.

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.

Fees.

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.

Additionally, the Township shall maintain a Tree Bank Fund as a depository for monies as specified in this chapter.

Review standards.

Granting of permits.

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:

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.

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.

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.

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.

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.

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.

Permit approval.

Time for approval.

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.

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.

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.

Duration of permits.

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.

If granted for a lot or parcel of land for which no building permit is required: one year from the date of issuance.

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.

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.

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.

If granted for a lot or parcel of land for which preliminary approval of a major subdivision is sought: until expiration of such approval.

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.

Inspection.

Pre-permit.

Prior to taking final action upon any application for tree removal and protection, an inspection of the site shall be made by:

A duly designated representative of the agency considering granting approval of the plan.

The Township Engineer or Planner or an arborist appointed by the Township and paid by the applicant as may be required for all other cases.

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.

Post-permit.

The holder of the tree removal permit shall notify the Township Engineer or Planner in writing at least four business days in advance to when he wishes to commence tree removal activity. However, no tree removal activity shall begin until the first post-permit site inspection takes place and approval to commence is given by the Township Engineer or Planner.

The notification shall also include description as to the manner of disposal of the removed trees. Where appropriate, the Township Engineer or Planner shall advise the Township Recycling Coordinator of the name of the permit holder, the location of the removal site, the date removal is to commence, and the manner of disposal to be employed.

Site inspection shall verify:

All trees identified to be removed in the application and accompanying sketch are marked by red ribbons attached to and completely circling the tree trunk, or by red paint sprayed around the trunk;

All trees identified to be saved in the application and sketch are visibly marked by blue ribbons attached to and completely circling the tree trunk;

The limit of disturbance line is identified per § 233-52F(3)(b) or § 233-52G(5) of this chapter;

Tree protection measures for all trees with DPM equal to or greater than eight inches, not scheduled for removal, as identified on the landscape plan or sketch, have been taken per § 233-52F(3)(b) or § 233-52G(5) of this chapter;

Any steep slope areas on the lot which may be impacted by tree removal activity are satisfactorily protected with silt fencing;

No tree removal activity has been undertaken, and no construction activity which may jeopardize trees to be saved has begun.

The inspector, upon completion of this first inspection, may verbally approve or deny commencement of tree removal activity, but shall follow up and issue a written notice within two business days. If a denial is issued, the written notice shall specify all reasons for the denial.

Subsequent inspections.

Upon denial. Should the first post-permit inspection result in denial to commence tree removal activity, the permit holder, when he believes he has satisfied all concerns, shall repeat the procedures of § 233-52L(2), and the inspector shall verify the requirements therein upon a repeat first inspection.

Upon approval.

Subsequent unannounced inspections can be made at any time during tree removal activity to verify continued site protection.

Second inspection.

Upon completion of tree removal activity, the permit holder shall notify the Township Engineer or Planner, requesting a second inspection. The second inspection shall verify:

[i]

All trees scheduled to be removed have been removed;

[ii]

Tree disposals have been made per the notice for first inspection;

[iii]

No trees identified to be saved have been compromised;

[iv]

Save-tree identification markings, limit of disturbance markings, and steep slope fencing all remain in place;

[v]

Tree protection measures remain in place.

Successful passing of the second inspection is a prerequisite for the issuance of a building permit when such is required. The Township Engineer or Planner shall issue a report in writing of the results of the second inspection within two business days.

Tree replacement. When tree replacements are specified by this section, a final inspection is to be performed. The permit holder shall request such an inspection in writing to the Township Engineer or Planner when all replacement trees have been planted and staked. Successful passing of the final inspection is a prerequisite to the issuance of a CO, where applicable, and the return of bond monies.

Enforcement.

The appropriately appointed or assigned Township official(s) or its Engineer or Planner shall enforce the provisions of this section. Enforcement means the following:

Withholding approval for the issuance of a building permit or CO, as applicable;

Requesting the Construction Official of the Township to issue a stop-work order; the Building Division shall act on this request within one business day;

Issuing a summons in Municipal Court; and

Withholding release, or confiscating, bond monies.

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.

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.

Tree Bank Fund management.

Locations. Tree Bank funds shall be allocated and expended with the following priority:

The applicant's lot(s) or development site(s);

Public parcels of land adjacent to the applicant's lot(s) or development site(s); and

Other inadequately forested public lands throughout the Township.

Tree Bank funds at a particular location shall be allocated and expended with the following priority:

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;

Planting trees where the Township Engineer or Planner or personnel approved by the Township Engineer or Planner have determined there is inadequate forestation;

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;

Properly disposing of trees that are dead, dying or diseased such as not to spread any disease or infestation to healthy trees; and

Preserving trees by performing appropriate tree maintenance as specified by the Township Engineer or Planner or personnel approved by the Township Engineer or Planner.

Nothing in this section shall prohibit the conformance with § 233-83H, Fire management. To the extent that any provision of this section is inconsistent with § 233-83H, the provisions of § 233-83H shall prevail.

[Added 9-12-2006 by Ord. No. 1665]

§ 233-53 Topsoil protection.

No topsoil shall be removed from the site or used as spoil. Topsoil moved during the course of construction shall be redistributed within the subdivision and shall be stabilized by seeding or planting.

§ 233-54 Monuments.

Monuments shall be of the size and shape required by Section 4 of Chapter 358 of the Laws of 1953[1] and shall be placed in accordance with said statute.

§ 233-55 Stormwater management.

[Last amended 4-13-2021 by Ord. No. 2043-2021]

Scope and purpose.

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.

Purpose.

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.

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.

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.

Goals and techniques

Through this section, the Township of Galloway has established the following goals for stormwater control:

To reduce flood damage, including damage to life and property;

To minimize any increase in stormwater runoff from new development;

To reduce soil erosion from any development or construction project;

To assure the adequacy of existing and proposed culverts and bridges, and other in-stream structures;

To maintain groundwater recharge;

To minimize any increase in nonpoint pollution;

To maintain the integrity of stream channels for their biological functions, as well as for drainage;

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.

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:

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.

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."

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.

Source control plans shall be developed based upon physical site conditions and the origin, nature and the anticipated quantity or amount of potential pollutants.

Structural BMPs, where necessary, shall be integrated with nonstructural stormwater management strategies and proper maintenance plans.

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.

Applicability.

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.

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:

Nonresidential major developments; and

Aspects of residential major developments that are not preempted by the Residential Site Improvement Standards at N.J.A.C. 5:21.

This section shall also be applicable to all major developments undertaken by the Township of Galloway.

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.

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.

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.

Procedure.

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.

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.

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.

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.

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.

Waivers. For good reason, the Township may grant a waiver of the standards given in Subsections C, D, E and F.

Compatibility with other permit and ordinance requirements.

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.

General standards. Design and performance standards for stormwater management measures.

Stormwater management measures for major development shall be developed to meet the erosion control, groundwater recharge, stormwater runoff quantity treatment as follows:

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.

The minimum standards for groundwater recharge, stormwater quality, and stormwater runoff quantity shall be met by incorporating green infrastructure.

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.

In the Pinelands Area of the Township of Galloway, the following criteria shall also apply:

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.

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.

Excessively and somewhat excessively drained soils as defined by the Soil Conservation Service should be avoided for the recharge of runoff wherever possible.

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.

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.

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.

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.

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.

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:

Headwalls and riprap.

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.

An eighteen-inch berm around the inside of the basin.

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.

Wetlands.

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.

A significant adverse impact shall be deemed to exist if:

A drainage structure is affected through the increased runoff discharged to the wetlands;

There is no change in the seasonal flow patterns;

There is an alteration of the water table; or

There is an increase in erosion and increased sedimentation of wetlands.

Methods of management.

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.

Detention/retention basins.

Rooftop storage.

Parking lot ponding.

Porous pavement and concrete lattice block surface.

Grassed channels and vegetated strips.

Routed flow over grass.

Decreased impervious area coverage.

French drains, porous pipes and dry wells.

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.

Regardless of the method used, the applicant will be required to provide a maintenance plan in accordance with Subsection K.

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.

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).

Drainage easements.

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.

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."

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.

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.

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.

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.

Lot grading standards and as-built surveys.

Design and construction standards for lot grading.

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.

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.

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.

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%.

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%.

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.

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.

As-built survey requirements.

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.

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.

Stormwater management requirements for major development.

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.

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.

Design standards for stormwater management measures are as follows:

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);

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);

Stormwater management measures shall be designed, constructed, and installed to be strong, durable, and corrosion-resistant.

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.

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.

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 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.

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.

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:

Best Management Practice	Maximum Contributory Drainage Area
Dry well	1 acre
Manufactured treatment device	2.5 acres
Pervious pavement systems	Area of additional inflow cannot exceed three times the area occupied by the BMP
Small-scale bioretention systems	2.5 acres
Small-scale infiltration basin	2.5 acres
Small-scale sand filter	2.5 acres

To satisfy the stormwater runoff quantity standards at Subsection D(18), the design engineer shall utilize BMPs from Table 1 or from Table 2 and/or an alternative stormwater management measure approved in accordance with Subsection D(7).

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).

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.

This subsection contains the minimum design and performance standards for groundwater recharge as follows:

The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at Subsection E, either:

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

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.

This groundwater recharge requirement does not apply to projects within the urban redevelopment area, or to projects subject to Subsection D(16)(d) below.

The following types of stormwater shall not be recharged:

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

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.

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.

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.

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:

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.

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.

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.

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.

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).

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.

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.

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.

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.

This subsection contains the minimum design and performance standards to control stormwater runoff quantity impacts of major development.

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:

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;

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;

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

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.

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:

The exception is consistent with that allowed by the Township of Galloway.

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.

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:

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

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:

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.

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.

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.

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:

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)];

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

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.

Calculation of stormwater runoff and groundwater recharge.

Stormwater runoff shall be calculated in accordance with the following:

The design engineer shall calculate runoff using one of the following methods:

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

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.

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).

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.

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.

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.

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.

Soils investigation requirements.

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:

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.

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.

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.

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.

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.

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.

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.

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.

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.

Percolation/permeability testing requirements.

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.

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.

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.

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.

Solids and floatable materials control standards.

Site design features identified under Subsection D(6) above, or alternative designs in accordance with Subsection D(7) above, to prevent discharge of trash and debris from drainage systems shall comply with the following standard to control passage of solid and floatable materials through storm drain inlets. For purposes of this subsection, "solid and floatable materials" means sediment, debris, trash, and other floating, suspended, or settleable solids. For exemptions to this standard see Subsection H(1)(b) below.

Design engineers shall use one of the following grates whenever they use a grate in pavement or another ground surface to collect stormwater from that surface into a storm drain or surface water body under that grate:

The New Jersey Department of Transportation (NJDOT) bicycle-safe grate, which is described in Chapter 2.4 of the NJDOT Bicycle Compatible Roadways and Bikeways Planning and Design Guidelines; or

A different grate, if each individual clear space in that grate has an area of no more than seven square inches or is no greater than 0.5 inches across the smallest dimension. Examples of grates subject to this standard include grates in grate inlets, the grate portion (non-curb-opening portion) of combination inlets, grates on storm sewer manholes, ditch grates, trench grates, and grates of spacer bars in slotted drains. Examples of ground surfaces include surfaces of roads (including bridges), driveways, parking areas, bikeways, plazas, sidewalks, lawns, fields, open channels, and stormwater system floors used to collect stormwater from the surface into a storm drain or surface water body.

For curb-opening inlets, including curb-opening inlets in combination inlets, the clear space in that curb opening, or each individual clear space if the curb opening has two or more clear spaces, shall have an area of no more than seven square inches or be no greater than two inches across the smallest dimension.

The standard in Subsection H(1)(a) above does not apply:

Where each individual clear space in the curb opening in existing curb-opening inlet does not have an area of more than nine square inches;

Where the municipality agrees that the standards would cause inadequate hydraulic performance that could not practicably be overcome by using additional or larger storm drain inlets;

Where flows from the water quality design storm as specified in N.J.A.C. 7:8 are conveyed through any device (e.g., end-of-pipe netting facility, manufactured treatment device, or a catch basin hood) that is designed, at a minimum, to prevent delivery of all solid and floatable materials that could not pass through one of the following:

A rectangular space 4.625 inches long and 1.5 inches wide (this option does not apply for outfall netting facilities); or

A bar screen having a bar spacing of 0.5 inches.

Note that these exemptions do not authorize any infringement of requirements in the Residential Site Improvement Standards for bicycle-safe grates in new residential development [N.J.A.C. 5:21-4.18(b)2 and 7.4(b)1].

Where flows are conveyed through a trash rack that has parallel bars with one-inch spacing between the bars, to the elevation of the Water Quality Design Storm as specified in N.J.A.C. 7:8.

Where the New Jersey Department of Environmental Protection determines, pursuant to the New Jersey Register of Historic Places Rules at N.J.A.C. 7:4-7.2(c), that action to meet this standard is an undertaking that constitutes an encroachment or will damage or destroy the New Jersey Register listed historic property.

Safety standards for stormwater management basins.

Applicability. This subsection sets forth requirements to protect public safety through the proper design and operation of stormwater management basins. This subsection applies to any new stormwater management basin.

The provisions of this section are not intended to preempt more stringent municipal or county safety requirements for new or existing stormwater management BMPs. Municipal and county stormwater management plans and ordinances may, pursuant to their authority, require existing stormwater management BMPs to be retrofitted to meet one or more of the safety standards in Subsection I(3)(a), (b), and (c) for trash racks, overflow grates, and escape provisions at outlet structures.

Requirements for trash racks, overflow grates and escape provisions.

A trash rack is a device designed to catch trash and debris and prevent the clogging of outlet structures. Trash racks shall be installed at the intake to the outlet from the stormwater management basin to ensure proper functioning of the basin outlets in accordance with the following:

The trash rack shall have parallel bars, with no greater than six-inch spacing between bars.

The trash rack shall be designed so as not to adversely affect the hydraulic performance of the outlet pipe or structure.

The average velocity of flow through a clean trash rack is not to exceed 2.5 feet per second under the full range of stage and discharge. Velocity is to be computed on the basis of the net area of opening through the rack.

The trash rack shall be constructed and installed to be rigid, durable, and corrosion-resistant, and shall be designed to withstand a perpendicular live loading of 300 pounds per square foot.

An overflow grate is designed to prevent obstruction of the overflow structure. If an outlet structure has an overflow grate, such grate shall meet the following requirements:

The overflow grate shall be secured to the outlet structure but removable for emergencies and maintenance.

The overflow grate spacing shall be no less than two inches across the smallest dimension.

The overflow grate shall be constructed and installed to be rigid, durable, and corrosion-resistant, and shall be designed to withstand a perpendicular live loading of 300 pounds per square foot.

For purposes of this subsection, "escape provisions" means the permanent installation of ladders, steps, rungs, or other features that provide easily accessible means of egress from stormwater management basins. Stormwater management basins shall include escape provisions as follows:

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.

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.

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.

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.

§ 233-55.1 Stormwater management in Pinelands Area.

[Added 2-28-2023 by Ord. No. 2103-2023]

Scope and purpose.

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.

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.

Applicability.

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).

This section shall apply within the Pinelands Area to all major development, and to minor development meeting the following criteria:

Development involving the construction of four or fewer dwelling units;

Development involving any nonresidential use and resulting in an increase of greater than 1,000 square feet of regulated motor vehicle surfaces; and

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.

This section shall apply to all development meeting the criteria of Subsection A(3)(b) above that is undertaken by Galloway Township.

Except as provided in § 233-55.1J, the exemptions, exceptions, applicability standards, and waivers of strict compliance contained in the NJDEP Stormwater Management Regulations at N.J.A.C. 7:8-1.1 et seq. shall not apply within the Pinelands Area.

Compatibility with other permit and ordinance requirements.

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.

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.

CONTRIBUTORY DRAINAGE AREA

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.

Definitions. For the purpose of this section, the following terms, phrases, words and their derivations shall have the meanings stated herein unless their use in the text of this section clearly demonstrates a different meaning. When not inconsistent with the context, words used in the present tense include the future, words used in the plural number include the singular number, and words used in the singular number include the plural number.

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).

Hydraulic impacts.

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.

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.

Design standards for stormwater management measures are as follows:

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);

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;

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;

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;

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;

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:

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;

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

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;

Dry wells shall be designed to prevent access by amphibian and reptiles;

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);

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;

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.

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).

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)

Green infrastructure standards.

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 of this section.

To satisfy the groundwater recharge and stormwater runoff quality standards at § 233-55.1C(15) and (16), the design engineer shall utilize BMPs identified in Table 1 at § 233-55.1C(5) and/or an alternative stormwater management measure approved in accordance with § 233-55.1C(6). The following green infrastructure BMPs are subject to the following maximum contributory drainage area limitations:

Best Management Practice	Maximum Contributory Drainage Area
Dry well	1 acre
Manufactured treatment device	2.5 acres
Pervious pavement system	Area of additional inflow cannot exceed three times the area occupied by the BMP
Small-scale bioretention systems	2.5 acres
Small-scale infiltration basin	2.5 acres
Small-scale sand filter	2.5 acres

To satisfy the stormwater runoff quantity standards at § 233-55.1C(17), the design engineer shall utilize BMPs identified in Table 1 or 2 at § 233-55.1C(5) and/or an alternative stormwater management measure approved in accordance with § 233-55.1C(6).

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).

(15)

Groundwater recharge standards.

This subsection contains the minimum design and performance standards for groundwater recharge as follows:

For all major development, the total runoff volume generated from the net increase in impervious surfaces by a the current ten-year, twenty-four-hour storm, as defined and determined in § 233-55.1D(8), shall be retained and infiltrated on-site.

[Amended 5-28-2024 by Ord. No. 2136-2024]

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 the current ten-year, twenty-four-hour storm, as defined and determined in § 233-55.1D(8), 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.

[Amended 5-28-2024 by Ord. No. 2136-2024]

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.

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.

This subsection contains the minimum design and performance standards to control stormwater runoff quality impacts of:

Major development;

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

Any development involving the grading, clearing, or disturbance of an area in excess of 5,000 square feet within any five-year period.

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:

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.

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.

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, and
A	=	the TSS Percent Removal Rate applicable to the first BMP
B	=	the TSS Percent Removal Rate applicable to the second BMP.

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).

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.

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:

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;

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;

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:

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

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

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.

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.

This subsection contains the minimum design and performance standards to control stormwater runoff quantity impacts related to applicable major and minor development.

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:

[Amended 5-28-2024 by Ord. No. 2136-2024]

Demonstrate through hydrologic and hydraulic analysis that for stormwater leaving the site, post-construction runoff hydrographs for the current and projected two-, ten-, and 100-year storm events, as defined and determined in § 233-55.1D(8) and (9), do not exceed, at any point in time, the preconstruction runoff hydrographs for the same storm events;

Demonstrate through hydrologic and hydraulic analysis that there is no increase, as compared to the pre-construction condition, in the peak runoff rates of stormwater leaving the site for the current and projected two-, ten- and 100-year storm events, as defined and determined in § 233-55.1D(8) and (9), 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;

Design stormwater management measures so that the post-construction peak runoff rates for the current and projected two-, ten- and 100-year storm events, as defined and determined in § 233-55.1D(8) and (9), are 50%, 75% and 80%, respectively, of the pre-construction peak runoff rates. The percentages apply only to the post-construction stormwater runoff that is attributable to the portion of the site on which the proposed development or project is to be constructed; or

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.

The stormwater runoff quantity standards shall be applied at the site's boundary to each abutting lot, roadway, watercourse, or receiving storm sewer system.

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.

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:

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

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.

Calculation of stormwater runoff and groundwater recharge.

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://directives.sc.egov.usda.gov/viewerFS.aspx?hid=21422 or at United States Department of Agriculture Natural Resources Conservation Service.

[Amended 5-28-2024 by Ord. No. 2136-2024]

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.

For the purpose of calculating curve numbers and groundwater recharge, there is a presumption that the pre-construction condition of a site or portion thereof is a wooded land use with good hydrologic condition. The term "curve number" applies to the NRCS methodology at Subsection D(1) above. A curve number 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).

[Amended 5-28-2024 by Ord. No. 2136-2024]

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.

The precipitation depths of the current two-, ten-, and 100-year storm events shall be determined by multiplying the values determined in accordance with Subsection D(8)(a) and D(8)(b) below:

[Added 5-28-2024 by Ord. No. 2136-2024]

The applicant shall utilize the National Oceanographic and Atmospheric Administration (NOAA), National Weather Service's Atlas 14 Point Precipitation Frequency Estimates: NJ, in accordance with the location(s) of the drainage area(s) of the site. This data is available at: https://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html?bkmrk=nj; and

The applicant shall utilize Table 5: Current Precipitation Adjustment Factors below, which sets forth the applicable multiplier for the drainage area(s) of the site, in accordance with the county or counties where the drainage area(s) of the site is located. Where the major development lies in more than one county, the precipitation values shall be adjusted according to the percentage of the drainage area in each county. Alternately, separate rainfall totals can be developed for each county using the values in the table below.

Table 5: Current Precipitation Adjustment Factors
County	Current Precipitation Adjustment Factors
County	2-Year Design Storm	10-Year Design Storm	100-Year Design Storm
Atlantic	1.01	1.02	1.03

For purposes of this subsection, "solid and floatable materials" means sediment, debris, trash, and other floating, suspended, or settleable solids. For exemptions to this standard see Subsection F(1)(b) below.

The New Jersey Department of Transportation (NJDOT) bicycle safe grate, which is described in Chapter 2.4 of the NJDOT Bicycle Compatible Roadways and Bikeways Planning and Design Guidelines; or

A different grate, if each individual clear space in that grate has an area of no more than seven square inches, or is no greater than 0.5 inches across the smallest dimension. Examples of grates subject to this standard include grates in grate inlets, the grate portion (non-curb-opening portion) of combination inlets, grates on storm sewer manholes, ditch grates, trench grates, and grates of spacer bars in slotted drains. Examples of ground surfaces include surfaces of roads (including bridges), driveways, parking areas, bikeways, plazas, sidewalks, lawns, fields, open channels, and stormwater system floors used to collect stormwater from the surface into a storm drain or surface water body.

For curb-opening inlets, including curb-opening inlets in combination inlets, the clear space in that curb opening, or each individual clear space if the curb opening has two or more clear spaces, shall have an area of no more than seven square inches, or be no greater than two inches across the smallest dimension.

The standard in Subsection F(1)(a) above does not apply:

Where each individual clear space in the curb opening in existing curb-opening inlet does not have an area of more than nine square inches;

Where the municipality agrees that the standards would cause inadequate hydraulic performance that could not practicably be overcome by using additional or larger storm drain inlets;

Where flows from the water quality design storm established at § 233-55.1C(16)(d) are conveyed through any device (e.g., end-of-pipe netting facility, manufactured treatment device, or a catch basin hood) that is designed, at a minimum, to prevent delivery of all solid and floatable materials that could not pass through one of the following:

A rectangular space 4.625 inches long and 1.5 inches wide (this option does not apply for outfall netting facilities); or

A bar screen having a bar spacing of 0.5 inches.

Where flows are conveyed through a trash rack that has parallel bars with one-inch spacing between the bars, to the elevation of the Water Quality Design Storm established at § 233-55.1C(16)(d); or

Where the NJDEP determines, pursuant to the New Jersey Register of Historic Places Rules at N.J.A.C. 7:4-7.2(c), that action to meet this standard is an undertaking that constitutes an encroachment or will damage or destroy the New Jersey Register listed historic property.

Galloway 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 expense of the inspection shall be billed against the stormwater management fund to be established for the inspection and review of stormwater management facilities.

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 fun in the amount equivalent to the cost of both ongoing maintenance activities and necessary structural replacements.

The requirements of Subsection I(2)(b), (c), and (d) above do not apply to stormwater management facilities that are dedicated to and accepted by the municipality or another governmental agency, subject to all applicable municipal stormwater general permit conditions, as issued by the Department.

In the event that the stormwater management facility becomes a danger to public safety or public health, or if it is in need of maintenance or repair, the municipality shall so notify the responsible person, in writing. Upon receipt of that notice, the responsible person shall have 14 days to effect maintenance and repair of the facility in a manner that is approved by the municipal engineer or his designee. The municipality, in its discretion, may extend the time allowed for effecting maintenance and repair for good cause. If the responsible person fails or refuses to perform such maintenance and repair, the municipality or County may immediately proceed to do so and shall bill the cost thereof to the responsible person. Nonpayment of such bill may result in a lien on the property.

Prior to granting 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 satisfactorily 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 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, and the method to finance the program.

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.

The applicant must submit escrows and guarantees as required in Article IX, § 233-65A(2), of the Galloway Land Management Code.

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;

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;

Two times per year: inspect for signs of damage to structures, repair eroded areas, check for signs of petroleum contamination and remediate;

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

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.

Additional guidance for the inspection, maintenance and repair of stormwater infiltration BMPs can be found in the NJ BMP Manual.

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.

Variances.

The exemptions, exceptions, applicability standards, and waivers of strict compliance contained in the NJDEP Stormwater Management Regulations at N.J.A.C. 7:8-1.1 et seq. shall not apply within the Pinelands Area except in accordance with this section.

The municipal review agency may grant a variance from the design and performance standards for stormwater management measures set forth in its municipal stormwater management plan and this section, provided that:

No variances shall be granted from § 233-55.1C(17)(d), which prohibits the direct discharge of stormwater runoff to any wetlands, wetlands transition area, or surface waterbody and the direction of stormwater runoff in such a way as to increase in 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;

The municipal stormwater plan includes a mitigation plan in accordance with N.J.A.C. 7:8-4.2(c)11 and N.J.A.C. 7:50-3.39(a)2.viii;

The applicant demonstrates that it is technically impracticable to meet any one or more of the design and performance standards on-site. 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;

The applicant demonstrates that the proposed design achieves the maximum possible compliance with the design and performance standards of this section on-site; and

A mitigation project is implemented, in accordance with the following:

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.

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.

The mitigation project shall be approved no later than preliminary or final site plan approval of the major development.

The mitigation project shall be constructed prior to, or concurrently with, the development receiving the variance.

The mitigation project shall comply with the green infrastructure standards at Subsection C(14).

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.

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).

A variance from the stormwater runoff quality standards at § 233-55.1C(16) may be granted if the following are met:

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

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:

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;

The mitigation project indirectly discharges to the same watercourse and is located upstream of the major development subject to the variance; and

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.

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.

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.

Each instance of engaging in a separate regulated activity in violation of this section shall be deemed a separate offense.

In addition, the Township may institute a civil action for injunctive or other relief to enforce the provisions of this section.
