ARTICLE VIII
Subdivisions: Design and Performance Standards
§ 220-139 General provisions.
A.
Any application for development shall demonstrate conformance to design standards that will encourage sound development patterns within the Township. Where either an Official Map or Master Plan has been adopted, the development shall conform to the proposals and conditions shown thereon. The streets, drainage rights-of-way, school sites, public parks and playgrounds, scenic sites, historic sites and flood control basins shown on the officially adopted Master Plan or Official Map shall be considered in the approval of plats. In accordance with good design practices, extreme deviations from rectangular lot shapes and straight lot lines shall not be allowed unless made necessary by special topographical conditions or other special conditions acceptable to the approving authority. All improvements shall be installed and connected with existing facilities or installed in required locations to enable future connections with approved systems or contemplated systems and shall be adequate to handle all present and probable future development.
B.
Character of the land. Land which the approving authority finds to be unsuitable for the intended lot(s) and their use due to flooding, improper drainage, steep slopes, soil conditions, adverse topography, utility easements or other features which can reasonably be expected to be harmful to the health, safety and general welfare of the present or future inhabitants of the development and/or its surrounding areas shall not be subdivided and site plans shall not be approved unless adequate and acceptable methods are formulated by the developer to solve the problems by methods meeting this chapter and all other regulations.
C.
Plats straddling municipal boundaries. Whenever a development abuts or crosses a municipal boundary, access to those lots within the Township shall be from within the Township as the general rule. Whenever access to a development is required across land in an adjoining community as the exception, the approving authority may require documentation that such access is legally established and that the access road is adequately improved.
D.
Development and street names. The proposed name of the development and streets shall not duplicate or too closely approximate the name of any other development or streets in the municipality. The approving authority shall have final authority to designate the name of the development and streets, which shall be determined at the sketch plat or preliminary application stage.

A.
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.
C.
Applicability.

The geographic area for which a stormwater management planning agency is authorized to prepare stormwater management plans, or a specific portion of that area identified in a stormwater management plan prepared by that agency.
Water flow on the surface of the ground or in storm sewers, resulting from precipitation.
A flood hazard area in which the flood elevation resulting from the two-, ten-, or 100-year storm, as applicable, is governed by tidal flooding from the Atlantic Ocean. Flooding in a tidal flood hazard area may be contributed to, or influenced by, stormwater runoff from inland areas, but the depth of flooding generated by the tidal rise and fall of the Atlantic Ocean is greater than flooding from any fluvial sources. In some situations, depending upon the extent of the storm surge from a particular storm event, a flood hazard area may be tidal in the 100-year storm, but fluvial in more frequent storm events.

Previously developed portions of areas:
A structure within, or adjacent to, a water, which intentionally or coincidentally alters the hydraulic capacity, the flood elevation resulting from the two-, ten-, or 100-year storm, flood hazard area limit, and/or floodway limit of the water. Examples of a water control structure may include a bridge, culvert, dam, embankment, ford (if above grade), retaining wall, and weir.
The ocean and its estuaries, all springs, streams, wetlands, and bodies of surface or groundwater, whether natural or artificial, within the boundaries of the State of New Jersey or subject to its jurisdiction.
An area that is inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances does support, a prevalence of vegetation typically adapted for life in saturated soil conditions, commonly known as "hydrophytic vegetation."

An alternative stormwater management measure, alternative removal rate, and/or alternative method to calculate the removal rate may be used if the design engineer demonstrates the capability of the proposed alternative stormwater management measure and/or the validity of the alternative rate or method to the municipality. A copy of any approved alternative stormwater management measure, alternative removal rate, and/or alternative method to calculate the removal rate shall be provided to the Department in accordance with § 220-153B. Alternative stormwater management measures may be used to satisfy the requirements at Subsection O only if the measures meet the definition of "green infrastructure" at § 220-148. Alternative stormwater management measures that function in a similar manner to a BMP listed at Subsection O(2) are subject to the contributory drainage area limitation specified at Subsection O(2) for that similarly functioning BMP. Alternative stormwater management measures approved in accordance with this subsection that do not function in a similar manner to any BMP listed at Subsection O(2) shall have a contributory drainage area less than or equal to 2.5 acres, except for alternative stormwater management measures that function similarly to cisterns, grass swales, green roofs, standard constructed wetlands, vegetative filter strips, and wet ponds, which are not subject to a contributory drainage area limitation. Alternative measures that function similarly to standard constructed wetlands or wet ponds shall not be used for compliance with the stormwater runoff quality standard unless a variance in accordance with N.J.A.C. 7:8-4.6 or a waiver from strict compliance in accordance with Subsection D is granted from Subsection O.
H.
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.
I.
Design standards for stormwater management measures are as follows:
(1)
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);
(2)
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 § 220-154B;
(3)
Stormwater management measures shall be designed, constructed, and installed to be strong, durable, and corrosion resistant. Measures that are consistent with the relevant portions of the Residential Site Improvement Standards at N.J.A.C. 5:21-7.3, 5:21-7.4, and 5:21-7.5 shall be deemed to meet this requirement;
(4)
Stormwater management BMPs shall be designed to meet the minimum safety standards for stormwater management BMPs at § 220-154; and
(5)
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.
J.
Manufactured treatment devices may be used to meet the requirements of this subchapter, provided the pollutant removal rates are verified by the New Jersey Corporation for Advanced Technology and certified by the Department. Manufactured treatment devices that do not meet the definition of "green infrastructure" at § 220-148 may be used only under the circumstances described at Subsection O(4).
K.
Any application for a new agricultural development that meets the definition of major development at § 220-148 shall be submitted to the Soil Conservation District for review and approval in accordance with the requirements at Subsections O, P, and Q 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.
L.
If there is more than one drainage area, the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsection P and Q 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.
M.
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 County Clerk. A form of deed notice shall be submitted to the municipality for approval prior to filing. The deed notice shall contain a description of the stormwater management measure(s) used to meet the green infrastructure, groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsection O, P and Q 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 § 220-155B(5). 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.
N.
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 § 220-148 of §§ 220-147 through 220-158 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 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 M 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 M above.
O.
Green infrastructure standards.
(1)
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.
(2)
To satisfy the groundwater recharge and stormwater runoff quality standards at Subsections P and Q, the design engineer shall utilize green infrastructure BMPs identified in Table 1 at Subsection F and/or an alternative stormwater management measure approved in accordance with Subsection G. The following green infrastructure BMPs are subject to the following maximum contributory drainage area limitations:
Best Management Practice | Maximum Contributory Drainage Area (acres) |
|---|---|
Dry well | 1 |
Manufactured treatment device | 2.5 |
Pervious pavement systems | Area of additional inflow cannot exceed 3 times the area occupied by the BMP |
Small-scale bioretention systems | 2.5 |
Small-scale infiltration basin | 2.5 |
Small-scale sand filter | 2.5 |
(4)
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 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 G may be used to meet the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsections P and Q.
(5)
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 P and Q, unless the project is granted a waiver from strict compliance in accordance with Subsection D.
P.
Stormwater runoff quality standards.
(1)
This subsection contains the minimum design and performance standards to control stormwater runoff quality impacts of major development. Stormwater runoff quality standards are applicable when the major development results in an increase of 1/4 acre or more of regulated motor vehicle surface.
(2)
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:
(a)
80% 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.
(b)
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.
(3)
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 P(2) above, unless the major development is itself subject to a NJPDES permit with a numeric effluent limitation for TSS or the NJPDES permit to which the major development is subject exempts the development from a numeric effluent limitation for TSS.
(4)
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.
(5)

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 BMP's that optimize nutrient removal while still achieving the performance standards in Subsections P and Q.
(8)
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.

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 approved pursuant to the Administrative Requirements for the Remediation of Contaminated Sites Rules, N.J.A.C. 7:26C, or Department landfill closure plan; and areas with high risks for spills of toxic materials, such as gas stations and vehicle maintenance facilities; and
[b]
Industrial stormwater exposed to source material. "Source material" means any material(s) or machinery, located at an industrial facility, that is directly or indirectly related to process, manufacturing or other industrial activities, which could be a source of pollutants in any industrial stormwater discharge to groundwater. Source materials include, but are not limited to, raw materials; intermediate products; final products; waste materials; by-products; industrial machinery and fuels, and lubricants, solvents, and detergents that are related to process, manufacturing, or other industrial activities that are exposed to stormwater.
[4]
The design engineer shall assess the hydraulic impact on the groundwater table and design the site so as to avoid adverse hydraulic impacts. Potential adverse hydraulic impacts include, but are not limited to, exacerbating a naturally or seasonally high water table so as to cause surficial ponding, flooding of basements, or interference with the proper operation of subsurface sewage disposal systems and other subsurface structures in the vicinity or down gradient of the groundwater recharge area.
(c)
In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at § 220-151, complete one of the following:
[1]
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 § 220-151D and E, respectively, of §§ 220-147 through 220-158, do not exceed, at any point in time, the preconstruction runoff hydrographs for the same storm events;
[2]
Demonstrate through hydrologic and hydraulic analysis that there is no increase, as compared to the preconstruction condition, in the peak runoff rates of stormwater leaving the site for the current and projected two-, ten-, and 100-year storm events, as defined and determined in § 220-151D and E, respectively, of §§ 220-147 through 220-158, 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; or
[3]
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 § 220-151D and E, respectively, of §§ 220-147 through 220-158, 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. The percentages shall not be applied to post construction stormwater runoff within tidal flood hazard areas if the design engineer demonstrates through hydrologic and hydraulic analysis that the increased volume, change in timing, or increased rate of stormwater runoff will not increase flood damages below the point of discharge;
(d)
The stormwater runoff quantity standards shall be applied at the site's boundary to each abutting lot, roadway, watercourse, or receiving storm sewer system.
(2)
Any application for a new agricultural development that meets the definition of major development at § 220-148 shall be submitted to the Freehold Soils Conservation District (FSCD) for review and approval in accordance with the requirements of this section and any applicable FSCD guidelines for stormwater runoff quantity and erosion control.

[Added 10-19-2006 by Ord. No. 2006-35; amended 12-18-2008 by Ord. No. 2008-41; 7-15-2021 by Ord. No. 2021-17; 6-20-2024 by Ord. No. 2024-017; 8-15-2024 by Ord. No. 2024-021]
A.
Stormwater runoff shall be calculated in accordance with the following:
(1)
The design engineer shall calculate runoff using the following methods:
(a)
The USDA Natural Resources Conservation Service (NRCS) methodology, including the NRCS Runoff Equation and Dimensionless Unit Hydrograph, as described in the NRCS National Engineering Handbook Section 4 - Hydrology and Technical Release 55 - Urban Hydrology for Small Watersheds; or 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://directives.sc.egov.usda.gov/viewerFS.aspx?hid=21422, or at United States Department of Agriculture Natural Resources Conservation Service, New Jersey State Office.
(2)
For the purpose of calculating curve numbers 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 "curve number" applies to the NRCS methodology at Subsection A(1)(a). 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).
(3)
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.
(4)
In computing stormwater runoff from all design storms, the design engineer shall consider the relative stormwater runoff rates and/or volumes of pervious and impervious surfaces separately to accurately compute the rates and volume of stormwater runoff from the site. To calculate runoff from unconnected impervious cover, urban impervious area modifications as described in the NRCS Technical Release 55 - Urban Hydrology for Small Watersheds and other methods may be employed.
(5)
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.
B.
Groundwater recharge may be calculated in accordance with the following: The New Jersey Geological Survey Report GSR-32, A Method for Evaluating Ground-Water Recharge Areas in New Jersey, incorporated herein by reference as amended and supplemented. Information regarding the methodology is available from the New Jersey Stormwater Best Management Practices Manual; at the New Jersey Geological Survey website at: https://www.nj.gov/dep/njgs/pricelst/gsreport/gsr32.pdf, or at New Jersey Geological and Water Survey, 29 Arctic Parkway, PO Box 420 Mail Code 29-01, Trenton, New Jersey 08625-0420.
C.
Designs of stormwater conduit systems shall utilize the twenty-five-year rainfall in accordance with § 220-151D(1) below.
D.
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(1) and (2) below:
(1)
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
(2)
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.

E.
Table 6: Future Precipitation Change Factors provided below sets forth the change factors to be used in determining the projected two-, ten-, and 100-year storm events for use in this chapter, which are organized alphabetically by county. The precipitation depth of the projected two-, ten-, and 100-year storm events of a site shall be determined by multiplying the precipitation depth of the two-, ten-, and 100-year storm events determined from the National Weather Service's Atlas 14 Point Precipitation Frequency Estimates pursuant to Subsection D(1) above, by the change factor in the table below, in accordance with the county or counties where the drainage area(s) of the site is located. Where the major development and/or its drainage area 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.

B.
General maintenance.
(1)
The design engineer shall prepare a maintenance plan for the stormwater management measures incorporated into the design of a major development.
(2)
The maintenance plan shall contain specific preventative maintenance tasks and schedules; cost estimates, including estimated cost of sediment, debris, or trash removal; and the name, address, and telephone number of the person or persons responsible for preventative and corrective maintenance (including replacement). The plan shall contain information on the BMP location, design, ownership, maintenance tasks and frequencies, and other details as specified in Chapter 8 of the NJ BMP Manual, as well as the tasks specific to the type of BMP, as described in the applicable chapter containing design specifics.
(3)
If the maintenance plan identifies a person other than the developer (for example, a public agency or homeowners' association) as having the responsibility for maintenance, the plan shall include documentation of such person's agreement to assume this responsibility, or of the developer's obligation to dedicate a stormwater-management facility to such person under an applicable ordinance or regulation.
(4)
Responsibility for maintenance shall not be assigned or transferred to the owner or tenant of an individual property in a residential development or project, unless such owner or tenant owns or leases the entire residential development or project. The individual property owner may be assigned incidental tasks, such as weeding of a green infrastructure BMP, provided the individual agrees to assume these tasks; however, the individual cannot be legally responsible for all of the maintenance required.
(5)
If the person responsible for maintenance identified under Subsection B(2) above is not a public agency, the maintenance plan and any future revisions based on Subsection B(7) below shall be recorded upon the deed of record for each property on which the maintenance described in the maintenance plan must be undertaken.
(6)
Preventative and corrective maintenance shall be performed to maintain the functional parameters (storage volume, infiltration rates, inflow/outflow capacity, etc.) of the stormwater management measure, including, but not limited to, repairs or replacement to the structure; removal of sediment, debris, or trash; restoration of eroded areas; snow and ice removal; fence repair or replacement; restoration of vegetation; and repair or replacement of nonvegetated linings.
(7)
The person responsible for maintenance identified under Subsection B(2) above shall perform all of the following requirements:
(a)
Maintain a detailed log of all preventative and corrective maintenance for the structural stormwater management measures incorporated into the design of the development, including a record of all inspections and copies of all maintenance-related work orders;
(b)
Evaluate the effectiveness of the maintenance plan at least once per year and adjust the plan and the deed as needed; and
(9)
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.
C.
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.

Each day of such violation's continuance shall be considered as a separate offense and shall be separately punishable. These penalties shall not be the exclusive remedy available, and nothing in §§ 220-147 through 220-158 shall prevent an applicant from obtaining injunctive relief.
§ 220-158 Mitigation plan for stormwater management.
[Added 10-19-2006 by Ord. No. 2006-35; amended 12-18-2008 by Ord. No. 2008-41; 7-15-2021 by Ord. No. 2021-17; 6-20-2024 by Ord. No. 2024-017; 8-15-2024 by Ord. No. 2024-021]
A.
Standards.
(1)
For the purposes of this section, "mitigation" shall incorporate the definition set forth in § 220-148 and shall include situations where the applicant has demonstrated the inability or impracticality of strict compliance with the stormwater management requirements set forth in N.J.A.C. 7:8 in addition to the requirements set forth in §§ 220-147 through 220-158.
(2)
The Township of Marlboro having jurisdiction over an application requiring a stormwater management plan shall have the jurisdiction to grant a waiver from strict compliance with the performance requirements of §§ 220-147 through 220-158 or the stormwater management plan. Pursuant to N.J.A.C. 7:8-4.6(a)1 page 28, the waiver may be granted where an applicant has demonstrated 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. The granting of the waiver 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 must demonstrate one of the following:
(a)
An inability to apply any of the best management practices and methodologies as defined and approved herein and in the stormwater management plan, due to an extraordinary and exceptional situation uniquely affecting the subject property or structures thereon, resulting in a peculiar and exceptional practical difficulty or undue hardship; or
(b)
That the purposes of §§ 220-147 through 220-158 and stormwater management plan can be advanced by a deviation from the best management practices and methodologies as defined and approved herein and in the stormwater management plan, where the benefits of such deviation substantially outweigh any detriment.
(3)
In requesting a waiver as to any application, the applicant may submit as reasons for the waiver the site conditions of the proposed project, including soils types; thin soil cover; low permeability soils, and/or shallow depths to groundwater (high groundwater levels), unique conditions which would create an unsafe design, or conditions which would provide a detrimental impact to public health, welfare, or safety.
(4)
The waiver cannot be granted due to conditions created by the applicant. If the applicant can comply with the requirements of §§ 220-147 through 220-158 and stormwater management plan through reducing the size of a project, the hardship is self-imposed, and therefore the Board lacks jurisdiction to grant any waiver under this section.
(5)
The applicant must propose a suitable mitigation method through the submission of a mitigation plan which will conform to the design and performance standards of §§ 220-147 through 220-158, through green infrastructure stormwater management measures, governing stormwater quality, quantity, and groundwater recharge. Approval of a waiver or exemption from any one of the three stormwater design standard criteria which include groundwater recharge, water quality, and water quantity provides no guarantee that, if requested, an exemption or waiver will be granted for either or both of the remaining criteria.
(6)
Supporting evidence for an exemption or waiver shall be prepared in the form of a stormwater management report which will be signed and sealed by a New Jersey licensed professional engineer. The report shall include at a minimum:
(a)
Detailed hydrologic and hydraulic calculations identifying the sizing criteria for each BMP and the stormwater collection system based upon the anticipated peak flow and/or volume.
(b)
A map of the planned project showing existing conditions with drainage boundaries and land features, including delineated wetlands, proposed improvements, including all BMPs, grading, utilities, impervious features, and landscaping.
(c)
Construction details for each BMP with appropriate contact information.
B.
Mitigation criteria. The mitigation requirements listed below offer a hierarchy of options that are intended to offset the effect on groundwater recharge, stormwater quantity control, and/or stormwater quality control to an equal or greater extent than was created by the granting of a waiver or exemption from the stormwater management requirements. The mitigation project shall be approved no later than preliminary or final site plan approval of the major development and shall comply with the green infrastructure standards at N.J.A.C. 7:8-5.3. The mitigation criteria are listed below in order of preference:
(1)
Identify, design, and implement a compensating measure to mitigate impacts for a project that is located in the same HUC 14 drainage area as the major development subject to the waiver. In these cases, the applicant will address the same issue within the design and performance standards for which the variance or exemption is being sought, and demonstrate that the proposed mitigating measures provide equal or greater compensation to offset the noncomplying aspect of the stormwater management system on-site. The developer must also ensure the long-term maintenance of the project as outlined in Chapters 8 and 9 of the NJDEP Stormwater BMP Manual. If the Township agrees to control a new stormwater management facility, arrangement in the form of an escrow account will be made to stipulate the payment amount, schedule, and long-term responsibilities of the facility to ensure that it functions to capacity.
(2)
Complete a project identified by the municipality as equivalent to the environmental impact created by the exemption or variance.
(a)
If these criteria cannot be met on-site, the Township has identified the retrofitting of existing basins as the primary mode for mitigation measures to follow. Through clearing sediment, expanding capacity, or bringing the basin into compliance with water quality standards, mitigation opportunities have the potential to significantly improve stormwater management issues that face Marlboro Township.
(b)
As many of the developments in Marlboro were constructed with curb and gutter drainage, stormwater is often funneled and released directly into an adjoining water body. As these methods are contrary to the stormwater management BMPs outlined in the NJDEP's BMP Manual and endorsed through the adoption of the state's new stormwater regulations, the retrofitting of these basins can dramatically improve the Township's existing stormwater management infrastructure. Mitigation projects can utilize a number of BMPs to offset the stormwater management of a project that is unable to comply with the new design standards. However, these BMPs, which may include sand filters, vegetative filters, or the incorporation of a manufactured treatment device, among other possibilities, will be engineered and applied on a site-by-site basis. In general, the engineering necessary to determine the mitigative measure that is most suited for a particular basin is the responsibility of the applicant, and must be determined and submitted by the applicant along with the particular project's site plan. Marlboro has identified locations within the Deep Run watershed where BMPs can be utilized to improve stormwater management and reduce flooding. These locations, which have been identified by catchment area, offer developers specific options such as improving culverts, or upgrading infrastructure to use as mitigative alternatives. Applicants that are seeking waivers for development proposals located within the Deep Run watershed are strongly encouraged to reference the 10 Subwatershed Impact Assessment and Implementation Project Summary Tables that are included within the Identification and Evaluation of Impairments Within the Deep Run Watershed Report. Copies of the aforementioned report are available at the Township Clerk's office.
(3)
Provide funding for municipal projects that would address existing stormwater impacts. The third and least preferable stormwater mitigation option is for the applicant to provide funding or partial funding for an environmental enhancement project that has been identified in the municipal stormwater management plan, or towards the development of a regional stormwater management plan. The contributed funds must be equal or greater than the cost to implement the required on-site stormwater measure for which relief is requested including the cost of land, easements, engineering design, and long- term maintenance. However, with this option, Marlboro Township, not the applicant, is ultimately responsible for the design, property acquisition, construction, construction management, maintenance (short-term and long- term) and follow-up study, unless that project and its prospective costs have been outlined within this mitigation plan. An applicant may also propose a mitigation project on a site that has not been identified in this mitigation plan. However, in each circumstance the selection of a mitigation project must incorporate the following requirements:
(a)
The project must be within the same area that would contribute to the receptor impacted by that project.
(b)
Legal authorization must be obtained to construct the project at the location selected. This includes the maintenance and any access needs for the project throughout its operation.
(c)
The mitigation project should be located close to the original development project. If possible, the mitigation project should be located at a similar distance from the identified sensitive receptor. This distance should not be based on actual location, but on a similar hydraulic distance to the sensitive receptor. For example, if a project for which a waiver is obtained discharges to a tributary, but the closest location discharges to the main branch of a waterway, it may be more beneficial to identify a location discharging to the same tributary.
(d)
It is preferable to have one location that addresses any and all of the performance standards waived, rather than one location for each performance standard.
(e)
The project location must demonstrate no adverse impacts to other properties.
(f)
Pursuant to N.J.A.C. 7:8-4.6(a)1 page 29, mitigation projects that address green infrastructure standards must use green infrastructure BMPs in Table 1, and/or an alternative stormwater management measure approved in accordance with § 220-150G 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 waiver. 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, as defined at § 220-150P(4) at a minimum, and is subject to the applicable contributory drainage area limitation specified at § 220-150G or § 220-150O(2) as applicable.
(g)
For projects addressing the groundwater recharge performance standard, a mitigation project site upstream of the location of the actual project site is preferable to a downstream location. Additionally, one of the following must be satisfied:
[1]
Pursuant to N.J.A.C. 7:8-4.6(a)1 page 29, the average annual groundwater recharge provided by the mitigation project must equal or exceed the average annual groundwater recharge deficit resulting from granting the waiver for the major development; or
[2]
Pursuant to N.J.A.C. 7:8-4.6(a)1 page 29, runoff infiltrated during the two-year storm from the mitigation project must equal or exceed the deficit resulting from granting the waiver from the required infiltration of the increase in runoff volume from preconstruction to post-construction from the major development.
(h)
Mitigation projects that address stormwater runoff quantity must satisfy the following:
[1]
Pursuant to N.J.A.C. 7:8-4.6(a)1 page 30, the applicant demonstrates, through hydrologic and hydraulic analysis, including the effects of the mitigation project, that the waiver will not result in increased flooding damage below each point of discharge of the major development;
[2]
Pursuant to N.J.A.C. 7:8-4.6(a)1 page 30, the mitigation project discharges to the same watercourse and is located upstream of the major development subject to the waiver; and
[3]
Pursuant to N.J.A.C. 7:8-4.6(a)1 page 30, the mitigation project provides peak flow rate attenuation in accordance with N.J.A.C. 7:8-5.6(b)3 for an equivalent or greater area than the area of the major development subject to the waiver. For the purposes of this demonstration, equivalent includes both size of the area and percentage of impervious surface and/or motor vehicle surface.
(i)
Mitigation projects that address stormwater runoff quality must satisfy the following:
[1]
Pursuant to N.J.A.C. 7:8-4.6(a)1 page 29, 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 waiver and must provide sufficient TSS removal to equal or exceed the deficit resulting from granting the waiver for the major development; and
[2]
Pursuant to N.J.A.C. 7:8-4.6(a)1 page 29, the mitigation project must remove nutrients to the maximum extent feasible in accordance with N.J.A.C. 7:8-5.5(f).
C.
Requirements for mitigation projects.
(1)
Whether the applicant is proposing the mitigation project, or Marlboro has identified the project within this mitigation plan, the following requirements for mitigation must be included in the project submission:
(a)
Impact from noncompliance. The applicant must provide a table to show the required values, and the values provided in the project, and include an alternatives analysis that demonstrates that on-site compliance was maximized to the greatest extent practicable.
(b)
Narrative and supporting information regarding the need for the waiver. The waiver cannot be granted for a condition that was created by the applicant. If the applicant can provide compliance with the stormwater rules through a reduction in the scope of the project, the applicant has created the condition and a waiver cannot be issued. The applicant must provide a discussion and supporting information of the site conditions that would not allow the construction of a stormwater management facility to provide compliance with these requirements, and/or if the denial of the application would impose an extraordinary hardship on the applicant brought about by circumstances peculiar to the subject property. The site conditions to be considered are soil type, the presence of karst geology, acid soils, a high groundwater table, unique conditions that would create an unsafe design, as well as conditions that may provide a detrimental impact to public health, welfare, and safety.
(c)
Sensitive receptor: identify the sensitive receptor related to the performance standard for which a waiver is sought. Demonstrate that the mitigation site contributes to the same sensitive receptor.
(d)
Design of the mitigation project: provide the design details of the mitigation project. This includes, but is not limited to, drawings, calculations, and other information needed to evaluate the mitigation project.
(e)
Responsible party. The mitigation project submission must list the party or parties responsible for the construction or maintenance of the mitigation project. Documentation must be provided to demonstrate that the responsible party is aware of, has authority to perform, and accepts the responsibility for the construction and the maintenance of the mitigation project. Under no circumstances shall the responsible party be an individual single-family homeowner.
(f)
Maintenance. The applicant must include a maintenance plan that addresses the maintenance criteria at N.J.A.C. 7:8-5 as part of a mitigation plan. In addition, if the maintenance responsibility is being transferred to Marlboro Township, or another entity, the entity responsible for the cost of the maintenance must be identified. Marlboro provides applicants with the option of conveying the mitigation project to the Township, provided that the applicant funds the cost of maintenance of the facility in perpetuity.
(g)
Permits. The applicant is solely responsible to obtain any and all necessary local, state, or other applicable permits for the identified mitigation project or measure. The applicable permits must be obtained prior to the municipal approval of the project for which the mitigation is being sought.
(h)
Construction. The applicant must demonstrate that the construction of the mitigation project will be completed prior to, or concurrently with, the major development project. A certificate of occupancy or final approval by the municipality for the application permit cannot be issued until the mitigation project or measure receives final approval. Any mitigation projects proposed by the municipality to offset the stormwater impacts of the Township's own projects must be completed within six months of the completion of the municipal project, in order to remain in compliance with Marlboro's NJPDES general permit.
(2)
In all instances the Township of Marlboro having jurisdiction over the application shall have the power to impose additional conditions as may be appropriate under the circumstances of the application. The Township of Marlboro shall make specific findings of fact and conclusions consistent with § 220-147 showing the inability or impracticality of strict compliance with §§ 220-147 through 220-158 and the stormwater management plan and justifying the approval of the applicant's mitigation plan, in order to satisfy the reporting requirements of the municipality's NJPDES permit and other applicable state law requiring the submission of reports to any state or county review agency. The Township of Marlboro shall also have the power to require mitigation as to applications which have received waivers from the New Jersey Department of Environmental Protection.
§ 220-159 Environmental impact report.
A.
An environmental impact report shall accompany all applications for major subdivision and site development plans and shall provide the information needed to evaluate the effects of the proposed development upon the environment and shall include data, be distributed, reviewed and passed upon by the approving board as follows.
B.
The environmental impact report shall include:
(1)
A description of the project complete with maps and drawings, including maps of the project site as it relates to the town and the region, how it is to be constructed and a construction schedule, and its location (site).
(2)
An inventory of existing environmental conditions at the project site and surrounding region, including air and water quality, water supply, soils, geology, topography, vegetation, animal life, land use, aesthetics and history and consideration of additional factors, dependent on the sizes and type of project.
(3)
A list of all licenses, permits and other approvals required by municipal, county or state law and the status of each. The approvals and permits should be required before final consideration of the site plan.
(4)
An assessment of the environmental impact of the project described in Subsection B(1) upon the factors described in Subsection B(2), including an evaluation of the public costs of the project. The public costs include additional schools, roads, police, etc., and indirect costs, such as the loss of open space.
(5)
A listing of all adverse environmental impacts, especially irreversible and irretrievable damage, that cannot be avoided.
(6)
A list of alternatives to the project, including "no project," and the reasons for their acceptability or nonacceptability. Alternatives should consider both short- and long-term environmental effects of the project.
(7)
A listing of steps proposed to minimize environmental damage to the site and region during construction and operation. The consideration of soil erosion, preservation of trees, protection of watercourses, protection of air resources and noise control are some factors to be considered here.
C.
Waiver. Notwithstanding the foregoing, the approving board may, at the request of an applicant, waive the requirements for an environment impact report if sufficient evidence is submitted to support a conclusion that the proposed development will have a slight or negligible environmental impact. Portions of such requirements may likewise be waived upon a finding that the complete report need not be prepared in order to evaluate adequately the environmental impact of a particular project.[1]

B.
Review of reports. The Township's Environmental Commission shall review the preliminary site investigation report and soil testing report and provide its recommendation to the board with jurisdiction over the application. In addition, the preliminary site investigation report and soil testing report shall be reviewed by the appropriate board professional who shall provide his or her recommendation to the board with jurisdiction over the application.
C.
Requirements for reports. The reports shall be conducted and submitted in two parts.
(1)
Preliminary site investigation report.
(a)
First, the applicant shall submit a preliminary site investigation report that shall have been prepared within six months of the applicant's submission that provides historical information on the previous uses of the proposed site so that potential contaminants or areas of concern can be identified prior to any soil sampling. The preliminary site investigation report shall be based upon diligent inquiry by the applicant and at a minimum shall contain the following:
[1]
Names of all present owners and operators, and all prior owners or operators of the site who have held an interest in the site in the last sixty (60) years.
[2]
Dates of ownership for each owner.

[11]
A delineation of any areas believed to be contaminated including identification of the contaminant(s) present.
(b)
The Environmental Commission and board professionals shall review the preliminary site investigation report within 45 calendar days of receipt. Incomplete preliminary site investigation reports shall be returned to the applicant with comments for resubmittal. Following the acceptance of the preliminary site investigation report, the applicant shall submit a soil sampling report unless the administrative officer shall have waived the soil sampling report requirement based upon the recommendations of the Environmental Commission and board professionals that indicate that the applicant has satisfactorily demonstrated that the site has not historically been used for either agricultural or industrial uses resulting in contamination of the site.
(2)
Soil sampling report.
(a)
If the submittal of a Soil Sampling Report has not been waived pursuant to Subsection C(1), then a soil sampling report must be submitted that demonstrates that the sampling locations and sampling depths were biased towards areas of greatest potential contamination. If there is no basis for biasing sampling locations, one sample shall be taken every two acres. A minimum of one sample shall be taken at the proposed site. Sampling locations shall be identified on the site plan and affixed with GPS coordinates.
(b)
Unless otherwise directed by the administrative officer, all samples shall be analyzed for lead and/or arsenic using USEPA Method SW-846-6010B, and a pesticide scan performed using USEPA Method SW-841-8081A. In the event additional contaminants are suspected to exist and/or identified in the preliminary site investigation report, the administrative officer may direct that appropriate analysis be performed using the applicable USEPA or NJDEP analytical protocol. The date(s) of the soil sampling event(s) must be provided, both by telephone and in writing, to the Township's Departments of Engineering, Planning and Zoning a minimum of 10 calendar days prior to the collection of the samples.
(c)
The soil sampling report shall contain a table listing lead, arsenic, pesticides and other contaminants analyzed with the result of each parameter analyzed for each sample. An evaluation of each contaminant, including its potential impact upon groundwater or nearby surface waters shall be included in the report. All sampling and analytical work, remediation, quality assurance and laboratory methods must be conducted in accordance with the most recent NJDEP Field Sampling Procedures Manual protocol in accordance with N.J.A.C. 7:26E-l et seq., Technical Requirements for Site Remediation.
(d)
In the event that a soil sampling report has not been submitted at the time that the application has been deemed complete, the board with jurisdiction over the application retains the authority to require that a soil sampling report be submitted by the applicant. The board with jurisdiction over the application may require a soil sampling report if it determines, based upon the records presented at the public hearing, and the testimony given, that there is reason to believe that the site is potentially contaminated. The board with jurisdiction over the application may require that the soil sampling report be submitted prior to making a final determination on the merits of the application, or it may require that the soil sampling report be submitted as a condition of approval of the application.
D.
Proof of remedial action.
(1)
In the event that remedial action is required, or has occurred, as a result of the presence of contaminants at the site in excess of the NJDEP soil or groundwater cleanup criteria, the applicant shall provide the following documentations with its application:
(a)
Remedial action work plans or remedial action reports submitted to the NJDEP in accordance with the applicable technical regulations for site remediation.
(b)
Copies of any correspondence from NJDEP indicating a deficiency with any plans or reports submitted.
(c)

§ 220-160 Fire protection.
A.
Wherever a central water supply system services a development, provision shall be made for fire hydrants along streets and/or on the walls of nonresidential structures as approved by the Municipal Fire Department or Municipal Engineer and in accordance with fire insurance rating organization standards.
B.
Where streams or ponds exist or are proposed on lands to be developed, facilities shall be provided to draft water for fire-fighting purposes. This shall include access to a public street suitable for use by fire-fighting equipment and construction of improvements to ponds, dams or similar on-site development where feasible. Such facilities shall be constructed to the satisfaction of the Municipal Engineer and Fire Department and in accordance with fire insurance rating organization standards.
§ 220-161 Floodplain regulations.
(Also see §§ 220-147 through 220-158, regarding stormwater management, and 220-173, Public use and service areas, in this article.)
A.
The purposes are:
(1)
To implement the land use rules and regulations promulgated by the New Jersey Department of Environmental Protection for floodways and the flood-fringe portion of a flood hazard area.
(2)
To discourage construction and regrading in flood hazard areas.
(3)
To prevent encroachments into flood hazard areas which would obstruct or constrict the area through which water must pass.
(4)
To prevent pollution of watercourses during low- or high-water periods by preventing the placing or storing of unsanitary or dangerous substances in the flood hazard areas.
B.
The flood hazard design elevation shall be determined on an individual basis based upon stream encroachment line data from the Division of Water Resources or, in the absence of that data, the flood elevation based on a one-hundred-year storm frequency. One or the other shall be delineated on the plat. In addition, the Municipal Engineer may, upon request of and at the expense of the applicant or at the request of the approving authority and with the consent of the landowner and at the applicant's expense, determine the precise location of a floodway and flood-fringe area by close inspection, field survey or other appropriate method and cause the same to be marked on the ground and on the plat, notifying the owner, the New Jersey Department of Environmental Protection, Division of Water Resources and the approving authority. The assistance of the United States Department of Agriculture, Soil Conservation Service, and the New Jersey Department of Environmental Protection, Division of Water Resources, may be sought to aid in delineating the flood hazard design elevation, except that where state or federal agencies shall subsequently publish any reports which delineate the flood hazard design elevation of a watercourse, said report shall be the officially delineated flood hazard area as if said report were published in this chapter.
C.
Any lot containing a floodway portion of a drainage course and on which it is proposed to regrade and to construct an improvement shall not be permitted unless the proposed use is permitted by this chapter, plat approval has been granted and a floodway permit has been issued by the New Jersey Department of Environmental Protection, Division of Water Resources, where required by state regulations.
D.
Any lot containing a flood-fringe portion of the flood hazard area and on which it is proposed to regrade and/or construct an improvement shall not be permitted unless the proposed use is permitted by this chapter and until plat approval has been granted.
E.
The procedure for reviewing any proposed regrading and/or construction shall be the same as set forth for plat review. No application shall be approved and no permit granted until all zoning violations have been corrected or a variance has been granted.
F.
Permitted uses in a flood-fringe portion of the flood hazard area shall be restricted to the following, provided they are permitted uses in the district in which the flood-fringe portion is located:
(1)
Agriculture: general farming, pasture, grazing, outdoor plant nurseries, horticulture, viticulture, truck farming, forestry, sod farming and wild crop harvesting.
(2)
Industrial-commercial: yards, loading areas and parking areas.
(3)
Recreation: golf courses, improved courts and playing fields, swimming areas, boat launching ramps, picnic and camping, and open space uses such as hiking trails.
(4)
Residential: lawns, gardens, parking areas and play areas.
G.
The applicant shall submit maps, reports and other appropriate documents permitting the approving authority to evaluate whether the proposal has an inherent low flood damage potential; does not obstruct flood flows or increase flood heights and/or velocities; does not affect adversely the water-carrying capacity of any delineated floodway and/or channel; does not increase local runoff and erosion; does not unduly stress the natural environment of the floodplain or degrade the quality of surface water or the quality and quantity of groundwaters; does not require channel modification or relocation; does not require fill or the erection of structures; and does not include the storage of equipment and materials.
H.
Upon reviewing the application, hearing the applicant's representation and reviewing comments received from other municipal agencies to which the application was forwarded for comment, the approving authority shall deny, approve subject to conditions or approve the application. Its conclusion shall be based on findings related to the above criteria.
§ 220-162 Grading and filling.
All lots being filled shall be filled with clean fill and/or topsoil in such a manner as to allow complete surface draining of the lot into local storm sewer systems or natural drainage rights-of-way.
§ 220-163 Height limits.
Penthouses or roof structures for the housing of stairways, tanks, ventilating fans, air-conditioning equipment or similar equipment required to operate and maintain the building, and fire or parapet walls, skylights, spires, cupolas, flagpoles, chimneys, water tanks or similar structures may be erected above the height limits prescribed by this chapter but in no case more than 25% more than the maximum height permitted in the district, except church spires and farm silos shall have no height restrictions.
§ 220-164 Lighting.
All parking, loading and unloading areas and walkways thereto and appurtenant passageways and driveways serving commercial, public office, industrial or other similar uses having off-street parking and loading areas and building complexes requiring area lighting shall be illuminated adequately during the hours between sunset and sunrise when the use is in operation. The lighting plan in and around the parking areas shall provide for nonglare, color-corrected lights focused downward. The light intensity provided at ground level shall be a minimum 0.3 footcandle anywhere in the areas to be illuminated and shall average a minimum of 0.5 footcandle over the entire area, and such lighting shall be provided by fixtures with a mounting height not to be more than 25 feet measured from the ground level to the center line of the light source or the height of the building if attached, whichever is lower, and spacing not to exceed five times the mounting height. Except for low-intensity sign and exterior building surface decorative lighting, for each fixture the total quantity of light in lumens radiated above a horizontal plane passing through the light source shall not exceed 7 1/2% of the total quantity of light in lumens emitted from the light source. Any other outdoor lighting, such as building and sidewalk illumination, driveways with no adjacent parking and ornamental light, shall be shown on the lighting plan in sufficient detail to allow determination of the effects on adjacent properties, traffic safety and overhead sky glow. The objective of these specifications is to minimize undesirable off-premises effects. No light shall shine directly into windows or onto streets and driveways in such manner as to interfere with or distract driver vision. To achieve these requirements, the intensity of such light sources, light shielding and similar characteristics shall be subject to site plan approval.
§ 220-165 Lots.
A.
Lot dimensions and area shall not be less than the requirements of the zoning provisions of this chapter.
B.
Insofar as is practical, side lot lines shall not deviate more than 10° from either the right angle of a straight street or the radial of a curved street.
C.
Each lot must front upon an approved public street at least 50 feet in width.
D.
Where extra width has been dedicated for widening of existing streets, lots shall begin at such new street line and all setbacks shall be measured from such line.
E.
Where there is a question as to the suitability of a lot or lots for their intended use due to factors such as poor drainage conditions or flood conditions, where percolation tests or test borings show the ground conditions to be inadequate for proper sewage disposal for on-lot sewage treatment or similar circumstances, the approving authority may, after adequate investigation, withhold approval of such lots. If approval is withheld, the approving authority shall give reasons and nature of investigation made, notify the applicant and enter same in the minutes.
F.
Corner lots. Structures located on a corner lot shall be set back from both streets the required front yard distance, but in no case less than required for a clear-sight triangle, and shall meet the front yard requirements on both streets.
G.
Interior residential lots; flat lot.
(1)
A lot of seven or less acres existing at the time of this chapter in any district where a single-family use is permitted may be subdivided for one and only one additional lot whose frontage on a public street shall be a fifty-foot-wide access lane. Such a lot layout shall be permitted only if it will not adversely affect the development of the remaining undeveloped land. This provision shall not apply to a lot subdivided under the rural residential provisions of this chapter. The frontage shall be measured at the street line, and the side lines of the access lane shall be reasonably perpendicular to such frontage so that the access lane created is reasonably suited for construction and use as a private lane or possible development of a Township street.
(2)
Both lots, exclusive of the access lane, shall meet the width, depth and area requirements of the schedule of limitations for that district in which such lots are located.
(3)
In the event that an additional lot or lots shall be subdivided along such access lane, the owner of the access lane shall, at his own expense, pave and improve said private lane for its entire length in accordance with all Township standards regulating street construction and the provisions of this chapter and shall offer such road to the Township as a public street as a condition of subdivision approval. Furthermore, such road improvements shall be made and necessary subdivision approval received prior to the issuance of a building permit for the additional dwelling or dwellings.
H.
Contiguous undersized lot or lots under one ownership are considered one lot.
§ 220-166 Monuments.
Monuments shall be the size and shape required by N.J.S.A. 46:23-9.12 of the Map Filing Law, as amended, and shall be placed in accordance with said statute and indicated on the final plat for minor and major subdivisions. All lot corners shall be marked with a monument or with a solid metal alloy pin of permanent character having a minimum length of four feet and minimum diameter of one inch; said markers shall be installed prior to granting of a certificate of occupancy, and installation of same shall not be included in performance or maintenance guaranties covered in § 220-30, Guaranties, inspections and developer's agreements. Lot corners marked in accordance with requirements of § 220-47A(6), Cluster development, are exempt from these lot corner marking requirements.
§ 220-167 Natural features.
Natural features such as trees, brooks, swamps, hilltops and views shall be preserved whenever possible. On individual lots, care shall be taken to preserve selected trees in order to enhance soil stability and the landscape treatment of the area.
§ 220-168 Off-site and off-tract improvements.
[Amended 5-14-1987 by Ord. No. 17-87]

A one-and-one-half-inch compacted wearing surface of bituminous concrete (FABC) shall be constructed thereon in accordance with Division 3, Section 10, of the aforesaid New Jersey State Highway Department specifications and amendments thereto.
(d)
When subbase conditions of proposed parking area are wet, springly or of such a nature that surfacing would be inadvisable without first treating the subbase, the treatment of the subbase shall be made in the following manner: The area shall be excavated to a depth of six inches to 12 inches below the proposed finished grade and filled with suitable subbase material as determined by the Township Engineer. Where required by the Township Engineer, a system of porous concrete pipe subsurface drains shall be constructed beneath the surface of the parking area and connected to a suitable drain. After the subbase material has been properly placed and compacted, the parking area surfacing material as described heretofore shall be spread thereon.
(2)
Curbing.
(a)
All off-street parking lots shall be provided with curbing or the equivalent so that vehicles cannot be driven onto required landscaped areas, buffer zones and street rights-of-way and so that each parking lot has controlled entrances and exits and drainage control.
(b)
Curbing or wheel stops shall be located to prevent any part of the vehicle from overhanging the street right-of-way property lines or internal sidewalks. Parking spaces shall not be an extension of any street right-of-way.
(3)
All off-street parking lots shall have adequate designations to indicate traffic flow and parking spaces.
E.
Access. Except for single-family dwellings, access points from any one lot crossing the street line shall be limited to a maximum of two means of ingress and two means of egress along the frontage of any single street, and the center lines of any separate access points shall be spaced at least 65 feet apart, and such access points shall handle no more than two lanes of traffic, be at least 150 feet from the street line of any intersecting street and be at least 40 feet from any property line. For all uses, continuous open driveways in excess of 16 feet at the street line shall be prohibited, except for nonresidential uses where driveways of more than 16 feet may be permitted with the approval of the approving authority after giving due consideration to the proposed width, curbing, direction of traffic flow, radii of curves and traffic lane divider. For all uses, curbing shall be either depressed at the driveway or rounded at the corners and the driveway connected with the street in the same manner as another street.
F.
Location, provision and maintenance of parking areas. Parking spaces shall be provided and maintained as long as the buildings and premises are used for the purposes indicated, and they may not be considered as provided unless reasonable precautions are taken to assure their use only by persons residing or employed in or visiting the building or premises for which they are provided. Required off-street parking spaces shall be on the same lot or premises as the use served regardless of the number of spaces required by this chapter. Off-street parking may occupy front, side and rear yard areas, subject to site plan approval, but shall be no closer than 20 feet to any street line. No parking of vehicles shall be permitted in fire lanes, driveways, aisles or turning areas and street rights-of-way. Nothing shall prohibit driveways for one-family dwellings from being considered one off-street parking space.
G.
Type of facility. Parking spaces for nonresidential facilities may be on the surface of the ground or within underground or other garage facilities.
H.
Sufficient number of spaces, access and parking space dimensions.
(1)
The provision of the parking spaces required for each use shall be held to be the minimum number of spaces required, and the owner shall provide the necessary additional spaces should experience indicate that the spaces provided are inadequate. All parking spaces shall include adequate driveway and necessary turning areas for handling the vehicles for which provision is made. Parking areas shall be designed to permit each motor vehicle to proceed to and from the parking space provided for it without requiring the moving of any other motor vehicle. The minimum dimensions of aisles and parking stalls shall be as shown below. Where the angle of parking is different on both sides of the aisle, the larger required aisle width shall prevail. It is the intention of this chapter that perpendicular, parallel and/or angle parking are to be permitted. Each is to be used where good engineering practice, traffic circulation and safety considerations indicate.

(2)
Islands with raised curbs located between adjacent rows of angle or perpendicular parking spaces and at the ends of rows shall be installed in all parking areas consistent with good engineering practice, traffic circulation and safety and maintenance considerations and in such a number and manner as to provide the landscaping required in such parking areas by § 220-169B. It is not intended to require islands between every pair of adjacent rows of parking spaces, but rather that the islands be placed in such a manner as to discourage the hazardous cross aisle traffic movement of vehicles in other than designated pathways. The minimum dimensions of these islands shall be as shown in the following diagram. (See also § 220-97E.)
 |
(3)
Existing parking facilities are not required to revise the existing parking layout in order to install island separations and angle and/or perpendicular parking as a general requirement of this section. In specific instances, such revision may be required under § 220-97A(7) as a consequence of findings of the Township Engineer or the Division of Highway Safety of the Township Police Department.
§ 220-170 Planned developments.

§ 220-171 Principal uses.
No lot shall have erected upon it more than one residential building. No more than one principal use shall be permitted on one lot, except for shopping centers receiving site plan approval where all uses are as permitted for that zone, and except agricultural uses where the residence and permitted agricultural uses are permitted on the same lot.
§ 220-172 Prior approved construction and uses.
Nothing in this chapter shall require any change in the plans, construction, size or designated use of any building, structure or part thereof for which any building permit or site plan approval has been granted before the enactment of this chapter, provided that construction from such plans shall have been started within one year after the enactment of this chapter and shall be diligently pursued to completion. The approving authority may extend the time limit for good cause.
§ 220-173 Public use and service areas.
A.
In large-scale development, easements along rear property lines or elsewhere for utility installations may be required. Such easements shall be at least 15 feet wide and located in consultation with the companies or Township departments and authorities concerned and, to the fullest extent possible, be centered on or adjacent to rear or side lot lines. Easement dedication shall be expressed on the plat in accordance with the drainage provisions of this chapter.[1]
B.
Conservation, drainage and utility right-of-way easement. Where a minor or major development is traversed by a watercourse, open drainageway, channel or stream or where the Master Plan, Official Map or natural resources inventory of the Township of Marlboro delineates a floodplain or conservation easement, a conservation, drainage and utility right-of-way easement shall be furnished to the Township by the developer.
(1)
The easement shall extend on both sides and shall follow the general course of the watercourse, open drainageway, channel or stream and shall extend from the center line of said course and a line approximately parallel to the top of the bank 25 feet distant back from it.
(2)

§ 220-175 Communications facilities.
[Added 4-24-1997 by Ord. No. 11-97]
The following regulations shall apply to the construction of communications facilities within the Township of Marlboro:
A.
Permitted in all zoning districts. Communications facilities shall be considered to be a permitted accessory use in all zoning districts of the Township of Marlboro. Where a communications facility is proposed to be located on a vacant parcel of property, however, said facility shall be deemed to be a permitted use until such time as another principal structure is constructed on the property. At such time, the communications facility shall then be considered to be a permitted accessory use.
B.
Permit required. No new or replacement communications facility shall be constructed within the Township of Marlboro until a permit has been received from the Municipal Engineer. Where two communications facilities are proposed to be located adjacent to one another, then only one permit shall be necessary for the two combined structures, provided that the total square footage of the combined structures does not exceed 80 square feet. If the combined total square footage exceeds 80 square feet, or if more than two facilities are proposed to be located adjacent to one another, then additional permit(s) shall be required. The word "adjacent" shall be construed for the purposes of this chapter to mean facilities that are constructed upon the same pad or are situated within five feet from another facility. In lieu of receiving a permit from the Municipal Engineer, an applicant may apply directly to the appropriate board of the Township in order to obtain permission for construction of the desired communications facility.
C.
Site plan approval. Site plan approval from the appropriate board of the Township shall be required for any proposed communications facility which is greater than seven feet in height or greater than 50 square feet as a footprint for a single facility or greater than 80 square feet as a footprint for two or more adjacent facilities. This calculation shall not include the pad or other base beneath the facility.
D.
Lot coverage; size of pad. Neither the pad beneath a communications facility nor the facility itself shall be included in the calculation of lot coverage for the lot upon which the same are to be located. In no event, however, shall the pad extend more than three feet beyond the perimeter of the facility.
E.
Submission of application and plan. Prior to the issuance of a permit, the applicant shall submit an application to the Municipal Engineer along with a detailed plan depicting the proposed construction. A form application may be received from the Engineering Department. The plan of construction must identify:
F.
Application fee. There shall be a nonrefundable application fee of $500 for each permit. This fee is necessary in order to cover the costs associated with the review of each permit application by the Engineering and Legal Departments of the Township. The fee shall be submitted to the Municipal Engineer along with the completed application and proposed plan for construction and shall be placed into a separate account to be kept by the Chief Financial Officer for this purpose.
G.
Time for action by Municipal Engineer; checklist of requirements. The Municipal Engineer shall act upon any application submitted for a permit (i.e., issue the permit or decline to issue the permit) within 20 days from the date of receipt of a complete application and construction plan from the applicant. Issuance of a permit shall be based upon a determination that the following checklist of requirements has been satisfied:
(1)
That the proposed construction shall not adversely affect the subject property or adjacent properties.
(2)
That adequate landscape buffering exists. Said buffering (either in its current or expected growth condition) shall not, however, in the opinion of the Municipal Engineer, be so large as to obstruct vision in a manner which would create an unsafe condition. In cases where adequate landscape buffering does not exist, the planting of such buffering to the satisfaction of the Municipal Engineer shall be a condition to the issuance of the permit.
(3)
That adequate safety devices exist in the area of the communications facility, if deemed necessary by the Municipal Engineer. In cases where adequate safety devices do not exist, the erection of same to the satisfaction of the Municipal Engineer shall be a condition to the issuance of the permit.
(4)
That the proposed communications facility and any accessory structure(s) related thereto are not located within a sight triangle.
(5)
That all property owners within 200 feet of the location of the proposed facility have been notified as set forth herein and have been given an opportunity to provide comments to the Municipal Engineer prior to the issuance of the permit. The two-hundred-foot radius surrounding the proposed facility shall be depicted upon a signed plan submitted to the Municipal Engineer from a licensed surveyor on behalf of the applicant. The applicant shall notify all property owners shown to be within said two-hundred-foot area by certified mail, return receipt requested, at the addresses indicated on the tax records of the Township. The notice shall be on a form to be provided by the Engineering Department which shall advise the adjacent property owners that they shall have a period of 14 days from the date of mailing of said notice to provide comments to the Municipal Engineer regarding the proposed construction. No permit application shall be deemed to be complete until all of the certified mail return receipts have been submitted to the Municipal Engineer verifying that the applicant has mailed said notice to all of the required adjacent property owners at their last known addresses as listed on the tax records of the Township. If any comments are received by the Municipal Engineer from adjacent property owners within said period, then the Municipal Engineer shall provide the applicant with an opportunity to respond to said comments prior to the Municipal Engineer's determination on the permit application.
(6)
That an easement or other legal approval for the location of the communications facility has been obtained from the owner of the affected property. A copy of the deed of easement or other legal document(s) evidencing said approval shall be submitted at the time of application for a permit.
(7)
That any alteration to the existing grade of the property as a result of the proposed construction shall not adversely impact upon existing drainage patterns.
(8)
That the construction and use of the proposed communications facility and any accessory structure(s) related thereto shall not endanger the health, safety or welfare of the inhabitants of the affected property, neighboring residents or the community in general.
H.
Denial of permit. In cases where the Municipal Engineer declines to issue the requested permit, the Municipal Engineer shall return the proposed construction plan to the applicant along with a dated written statement outlining the reasons for said denial. Any applicant who is denied a permit to construct a communications facility within the Township of Marlboro may take any other action(s) as may be prescribed by the Municipal Land Use Law, P.L. 1975, c. 291 (N.J.S.A. 40:55D-1 et seq.), as amended from time to time, in order to secure approval to construct the desired communications facility.
