[Amended 5-5-2005 by Ord. No. 2005-17]
There shall be included by reference in this section all language set forth in §
220-140A through
F, inclusive, except that Subsection
D will now present guidelines along with an appendix which outlines the maximum area allowed for an accessory structure by zoning designation. The following regulations shall apply to all accessory buildings and structures:
A. Accessory buildings or structures as part of principal buildings. Any accessory buildings or structures attached to a principal building shall be considered part of the principal building, and the total structure shall adhere to the yard requirements for the principal building regardless of the technique of connecting the principal and accessory buildings or structures.
B. Accessory buildings or structures are not to be constructed prior to principal buildings. No building permit shall be issued for the construction of an accessory building or structure prior to the issuance of a building permit for the construction of the principal building upon the same premises. If construction of the principal building does not precede or coincide with the construction of the accessory building or structure, the Building Inspector shall revoke the building permit for the accessory building or structure until construction of the main building has proceeded substantially toward completion.
C. Distance between adjacent buildings or structures. The minimum distance between an accessory building or structure and any other building(s) on the same lot shall be 10 feet, except that no commercial poultry or brooder house shall be erected nearer than 400 feet to any dwelling on the same lot and no livestock shelter shall be erected nearer than 100 feet to any dwelling on the same lot or adjacent lot, and except that accessory buildings or structures other than poultry or brooder houses may be placed a minimum of 10 feet from underground structures, such as the water area of swimming pools, provided such accessory buildings or structures are a minimum of 10 feet from any aboveground principal or accessory building or structure, and except that portable hot tubs/spas shall be permitted less than 10 feet from any building or structure on the same lot.
[Amended 1-3-2019 by Ord. No. 2018-23]
D. Height and area requirements.
(1) The maximum permitted accessory structure area shall be determined by taking 25% of the square footage of the maximum principal building coverage for each zoning classification. The area of the accessory structure shall be determined in accordance with the
Lot and Building Coverage Standards Table below.
(2) These requirements exclude all uncovered pervious accessory structures such as patios, water area of pools, and decks constructed 18 or more inches above the ground that are gapped to permit infiltration from the building coverage requirements, while meeting total lot coverage limitations.
(3) Except for agricultural uses, the height of any accessory structure shall not exceed 25 feet or the principal building height.
E. Location.
[Amended 10-4-2007 by Ord. No. 2007-21; 6-13-2013 by Ord. No. 2013-12]
(1) Accessory buildings or structures may be erected on lots in accordance with the schedule of limitations, except that no commercial animal shelter shall be erected nearer than 500 feet, or any livestock shelter nearer than 100 feet, to any lot line, and except that these provisions shall not apply to parking spaces in front yards. If located in a front yard, accessory buildings or structures shall be set back a minimum of twice the distance from any street line than is required for a principal building. Accessory structures in second front yards shall be set back the same distance from the street line as the principal structure is required to be set back. If located on a corner lot, the provisions of this chapter also apply.
(2) The setbacks for
sheds that are placed on a property as an accessory structure shall be as follows within a residential zone:
[Amended 11-14-2013 by Ord. No. 2013-15]

(c) Sheds shall not be larger than 200 square feet and not taller than 11 feet in height, and shall be set back a minimum of five feet from side and rear property lines on lots greater than 40,000 square feet.
(d) Not more than one such shed shall be permitted to be placed on the property.
F. Seasonal housing. Housing provided on farms for seasonal employees shall be set back at least 300 feet from any public street, 400 feet from any property line and 500 feet from the permanent farm residence of the farm.
Whenever title to two or more contiguous lots is held by the same owner, regardless of whether or not each of said lots may have been approved as portions of a subdivision or acquired by separate conveyance or by other operation of law and one or more of said individual lots should not conform to the minimum lot area and dimension requirements for the zone in which it is located, the contiguous lots of said owner shall be considered as a single lot and the provisions of the chapter shall hold. Whenever land has been dedicated or conveyed to the Township for road widening purposes by the owner of a lot existing at the time of adoption of this chapter in order to implement the Official Map or Master Plan of the Township, the Building Inspector may issue building permits and certificates of occupancy for the lot whose depth and/or area are rendered substandard because of such dedication and where the owner has no other adjacent lands to provide the minimum requirements.
In all developments subject to §
220-184C or the cluster development provisions of this chapter, the approving authority may, depending on the probable volume of bicycle traffic, the development's location in relation to other populated areas, its location with respect to any overall bike route plans for the Township and county, public safety considerations and overall feasibility and practicality, require paved bike paths within the seventy-five-foot-wide dedicated land strip along existing streets. Bike paths shall be 6 1/2 feet wide, shall be constructed in accordance with the requirements for light-traffic parking areas covered by these regulations, shall have maximum grade requirements as is applicable to the street paralleled and shall be equipped with suitable regulatory signs, and where bike paths intersect streets, the curbing shall be ramped for bicycle access to the street grade.
Buffer areas are required along property, zoning district and/or street lines of all commercial lots or where said property lines or the center line of the street are also zoning district lines. Buffer areas shall comply with the following standards:
A. The buffer area shall be located in the district which requires it and shall be measured from the district boundary line or from the near street line where that street center line serves as the district boundary line.
B. Buffer areas shall be maintained and kept clean of all debris, rubbish, weeds and tall grass.
C. No structure, activity, storage of materials or parking of vehicles shall be permitted in the buffer area, except for access drives from public streets, directional and safety sign per each direction of traffic per access drive.
D. Buffer widths shall be established in each zoning district. The buffer area shall be planted and maintained with grass or ground cover, massed evergreens and deciduous trees and shrubs of such species and size as will produce within two growing seasons a screen of at least four feet in height and of such density as will obscure throughout the full course of the year all of the glare of automobile headlights emitted from the premises.
(1) The screen planting shall be maintained permanently and any plant material which does not live shall be replaced within one year.
(2) The screen planting shall be so placed that at maturity it will be not closer than three feet away from any street or property line.
(3) A clear-sight triangle shall be maintained at all street intersections and at all points where private accessways intersect public streets. Private accessways shall maintain a sight triangle by having no plantings, gradings or structures higher than three feet above the street center line located within the street right-of-way between the edge of the paved cartway and the street right-of-way line.
(4) vehicular and pedestrian ingress and egress.
(5) required in this chapter.
E. No screen planting shall be required along streets which form district boundary lines, provided that only the front of any proposed building shall be visible from the adjacent residential district.
F. In addition to the buffer areas otherwise required by this chapter, buffer areas are required along lot and street lines of all residential lots within any major subdivision of five acres or more where such property lines or the center lines of such adjacent streets abut a farm. The minimum width of such buffer areas shall be the greater of 25 feet or the width otherwise required for buffers within that zone. It is the intent of this section to shift the burden of providing buffers and separation between agricultural and residential uses to such residential uses to the extent reasonable and practicable.
[Added 2-16-2006 by Ord. No. 2006-1]
Nothing in this chapter shall require any change in a building permit, site plan or zoning variance which was approved before the enactment of this chapter but is in violation of this chapter, provided that construction based on such a building permit shall have been started within one year following the effective date of this chapter and, in the case of a site plan or variance, a building permit shall have been issued within one year following the effective date of this chapter and in all instances the project shall be continuously pursued to completion, otherwise said approvals and permits shall be void. The approving authority may extend these time intervals for good cause.

(b) Aspects of residential major developments that are not regulated by the Residential Site Improvement Standards at N.J.A.C. 5:21.
(2) Sections
220-147 through
220-158 shall also be applicable to all major developments undertaken by Township of Marlboro.
D. Compatibility with other permit and ordinance requirements. Development approvals issued for subdivisions and site plans pursuant to §§
220-147 through
220-158 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 §§
220-147 through
220-158 shall be held to be the minimum requirements for the promotion of the public health, safety, and general welfare. Sections
220-147 through
220-158 are not intended to interfere with or annul any other ordinances, rule or regulation, statute, or other provision of law except that, where any provision of these sections 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 apply.

G. 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, 7.4, and 7.5 shall be deemed to meet this requirement;
(4) Stormwater management basins shall be designed to meet the minimum safety standards for stormwater management basins 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 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 §
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 onsite and no adverse environmental impact would occur as a result of compliance with any one or more of the individual standards being determined utilizing a weighted average of the results achieved for that individual standard across the affected drainage areas.
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 this chapter 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 Subsection
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 |
---|
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 |
(3) To satisfy the stormwater runoff quantity standards at Subsection
Q, 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
G.
(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 Subsection
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) 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.
(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.

B | = | the TSS percent removal rate applicable to the second BMP |
(6) 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.
(7) 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.
(8) 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.
(9) 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.
(10) 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.
Q. Erosion control, groundwater recharge and stormwater runoff quantity standards.
(1) This subsection contains minimum design and performance standards to control erosion, encourage and control infiltration and groundwater recharge, and control stormwater runoff quantity impacts of major development.
(a) The minimum design and performance standards for erosion control are those established under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq., and implementing rules.
(b) The minimum design and performance standards for groundwater recharge are as follows:
[1] The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at §
220-151, either:
[a] Demonstrate through hydrologic and hydraulic analysis that the site and its stormwater management measures maintain 100% of the average annual preconstruction groundwater recharge volume for the site; or
[b] Demonstrate through hydrologic and hydraulic analysis that the increase of stormwater runoff volume from preconstruction to post construction for the two-year storm is infiltrated.
[2] This groundwater recharge requirement does not apply to projects within the urban redevelopment area, or to projects subject to Subsection
Q(1)(b)[3] below.
[3] The following types of stormwater shall not be recharged:
[a] Stormwater from areas of high pollutant loading. High pollutant loading areas are areas in industrial and commercial developments where solvents and/or petroleum products are loaded/unloaded, stored, or applied; areas where pesticides are loaded/unloaded or stored; areas where hazardous materials are expected to be present in greater than reportable quantities, as defined by the United States Environmental Protection Agency (EPA) at 40 CFR 302.4; areas where recharge would be inconsistent with Department-approved remedial action work plan or landfill closure plan and areas with high risks for spills of toxic materials, such as gas stations and vehicle maintenance facilities; and
[b] Industrial stormwater exposed to source material. "Source material" means any material(s) or machinery, located at an industrial facility, that is directly or indirectly related to process, manufacturing or other industrial activities, which could be a source of pollutants in any industrial stormwater discharge to groundwater. Source materials include, but are not limited to, raw materials; intermediate products; final products; waste materials; by-products; industrial machinery and fuels, and lubricants, solvents, and detergents that are related to process, manufacturing, or other industrial activities that are exposed to stormwater.
[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 two-, ten-, and 100-year storm events do not exceed, at any point in time, the preconstruction runoff hydrographs for the same storm events;
[2] Demonstrate through hydrologic and hydraulic analysis that there is no increase, as compared to the preconstruction condition, in the peak runoff rates of stormwater leaving the site for the two-, ten-, and 100-year storm events and that the increased volume or change in timing of stormwater runoff will not increase flood damage at or downstream of the site. This analysis shall include the analysis of impacts of existing land uses and projected land uses assuming full development under existing zoning and land use ordinances in the drainage area; or
[3] Design stormwater management measures so that the post construction peak runoff rates for the two-, ten-, and 100-year storm events are 50%, 75% and 80%, respectively, of the preconstruction peak runoff rates. The percentages apply only to the post construction stormwater runoff that is attributable to the portion of the site on which the proposed development or project is to be constructed. The percentages shall not be applied to post construction stormwater runoff into tidal flood hazard areas if the increased volume 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]
A. Stormwater runoff shall be calculated in accordance with the following:
(1) The design engineer shall calculate runoff using one of 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://www.nrcs.usda.gov/Internet/FSE DOCUMENTS/stelprdb1044 171.pdf, or at United States Department of Agriculture Natural Resources Conservation Service, 220 Davison Avenue, Somerset, New Jersey 08873; or
(b) 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.
(2) 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 at Subsection
A(1)(a) and the rational and modified rational methods at Subsection
A(1)(b). A runoff coefficient or a groundwater recharge land cover for an existing condition may be used on all or a portion of the site if the design engineer verifies that the hydrologic condition has existed on the site or portion of the site for at least five years without interruption prior to the time of application. If more than one land cover has existed on the site during the five years immediately prior to the time of application, the land cover with the lowest runoff potential shall be used for the computations. In addition, there is the presumption that the site is in good hydrologic condition (if the land use type is pasture, lawn, or park), with good cover (if the land use type is woods), or with good hydrologic condition and conservation treatment (if the land use type is cultivation).
(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.

(a) The trash rack shall have parallel bars, with no greater than six-inch spacing between the bars.
(b) The trash rack shall be designed so as not to adversely affect the hydraulic performance of the outlet pipe or structure.
(c) 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.
(d) 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.
(2) 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:
(a) The overflow grate shall be secured to the outlet structure but removable for emergencies and maintenance.
(b) The overflow grate spacing shall be no less than two inches across the smallest dimension.
(c) 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.
(3) Stormwater management basins shall include escape provisions as follows:
(a) If a stormwater management Basin has an outlet structure, escape provisions shall be incorporated in or on the structure. Escape provisions include the installation of permanent ladders, steps, rungs, or other features that provide easily accessible means of egress from stormwater management basins. With the prior approval of the municipality pursuant to Subsection
B, a freestanding outlet structure may be exempted from this requirement;
(b) 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. Safety ledges shall be comprised of two steps. Each step shall be four to six feet in width. One step shall be located approximately 2 1/2 feet below the permanent water surface, and the second step shall be located one to 1 1/2 feet above the permanent water surface. See Subsection
D for an illustration of safety ledges in a stormwater management basin; and
(c) 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.
C. 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, the Township of Marlboro, the County of Monmouth or the Department that the variance or exemption will not constitute a threat to public safety.

[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]
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 board 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. 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) 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] 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] 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] 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] The mitigation project discharges to the same watercourse and is located upstream of the major development subject to the waiver; and
[3] 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] 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] 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 board having jurisdiction over the application shall have the power to impose additional conditions as may be appropriate under the circumstances of the application. The Board 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 Board shall also have the power to require mitigation as to applications which have received waivers from the New Jersey Department of Environmental Protection.
[Added 10-16-2008 by Ord. No. 2008-29]
A. Filing of report.
(1) Prior to any development application (including major or minor subdivision and site plan approvals) being deemed complete by the Township's administrative officer, a preliminary site investigation report and soil sampling report, as set forth in this section, shall be filed by the applicant.
(2) Exemptions. No applicant shall be required to submit a preliminary site investigation report and soil testing report for the following types of applications:
(a) Applications for signage;
(b) Applications for bulk variances in connection with decks, pools, and/or sheds for existing uses;
(c) Applications for minor subdivisions which create no new lots;
(d) Applications for site plan waivers;
(e) Applications making minor revisions to existing site plans;
(f) Applications involving open space and continued farming; and
(g) Applications for sites for which final approval has previously been granted.
(3) Notwithstanding the foregoing exemptions, a preliminary site investigation report and soil sampling report may be required at the direction of the respective land use board with jurisdiction over the application if the Planning or Zoning Board finds that, based upon historical data, there is reason to believe that the site is potentially contaminated.
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.
[3] Dates of operation of each owner.
[4] Description of past agricultural or industrial use of the site.
[5] List of pesticides, herbicides, insecticides or other contaminants used or stored at the site.
[6] Approximate period of time of use or storage of pesticides, herbicides, insecticides or other contaminant(s), as the term "contaminant" is defined in N.J.A.C. 7:26E-1.8, at the site.
[7] Records relating to any past remedial activities.
[8] Copies of all present and prior sampling data.
[9] A scaled site plan or survey detailing lot/block numbers, property boundaries, buildings, storage or use areas for any pesticides, herbicides, insecticides or other contaminants, wetlands, streams, ponds, septic and cesspool systems, underground storage tanks, and inactive and active wells.
[10] Identification and delineation of all areas where nonindigenous fill materials were used on site.
[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) Copies of the no further action letter issued by NJDEP, including any conditions imposed by NJDEP thereto.
(d) Copies of any filed deed notices applicable to the site.
(2) The Board with jurisdiction over the application may condition the approval of any development upon the requirement that a full site no further action letter be obtained from the NJDEP pursuant to N.J.S.A. 40:48-2.57.
(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.
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.
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.
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.
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.
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.
[Amended 5-14-1987 by Ord. No. 17-87]
A. The Planning Board and/or the Board of Adjustment shall require, as a condition of final subdivision and site plan approval, that the developer pay his pro rate share of the cost of providing reasonable and necessary street improvements and water, sewerage and drainage facilities and other facilities necessary for the health, safety and welfare of the public and easements therefor located outside the property limits of the development but necessitated or required by construction or improvements within such development. Such contribution for a developer's pro rata share shall be required where the off-tract improvements are to be constructed pursuant to provisions of the circulation and comprehensive utility service plans and other relevant or appropriate plans included in the Marlboro Township Master Plan. The developer shall contribute his pro rata share of the costs, except that in the case where all costs for the required improvements can be properly allocated to the developer, he may be required to install the improvement.
B. The developer shall pay the full cost or shall be required to construct off-tract improvements that are wholly necessitated by the proposed development where said improvements do not benefit any land other than the land within the subdivision or site plan.
C. The developer shall provide for payment of its pro rata share, as determined in Subsections
E and
F of this section of all off-tract improvements required by the Planning Board or the Board of Adjustment if such improvements are wholly or partially necessitated by the proposed development where said improvements benefit lands other than those within the subdivision or site plan.
D. The developer shall deposit with the Township a percentage of the total cost of the necessary improvements equal to the percent of benefit which said development will receive from the necessary improvements in relation to the total benefit resulting from the necessary improvement to all properties as developed or potentially developed.
E. In apportioning the benefits of off-tract improvements as between the developer and other property owners and the general public, the Planning Board shall be guided by the following factors:
(1) The increase in market values of the properties affected and any other benefits conferred.
(2) The needs created by the application.
(3) Population and land use projections for the land within the general area of the subdivision or site plan and other areas to be served by the off-tract improvements.
(4) The estimated time for construction of the off-tract improvements.
F. Without limiting the generality of the foregoing, the Planning Board may take into account the following specific factors:
(1) With respect to street widening, alignment, curbs, gutters, streetlights, sidewalks, street signs, and traffic signalization improvements, the Planning Board may consider:
(b) Existing and projected traffic patterns.
(c) Quality of roads and sidewalks in the area.
(d) Such other factors as it may deem relevant to the needs created by the proposed development.
(e) Functional capacity of roads.
(f) Local bridges, county bridges and other county improvement.
(2) With respect to drainage facilities, the Planning Board or the Board of Adjustment may consider:
(a) The relationship between the areas of the subdivision or site plan and the area of the total drainage basin of which the subdivision or site plan is a part.
(b) The proposed use of land within the subdivision or site plan and the amount of land area to be covered by impervious surfaces on the land within the subdivision or site plan.
(c) The use, condition or status of the remaining land area in the drainage basin.
(3) With respect to sewerage facilities, the Planning Board may consider:
(b) Projected future loadings to the system.
(c) Condition of the existing sewerage facilities.
(d) Amount of infiltration/inflow in the existing system.
(e) The use, condition or status of the remaining land in the sanitary sewer service area.
(f) The reports of the Marlboro Township Municipal Utilities Authority and the Western Monmouth Utilities Authority with regard to this proposed development.
(4) Any reports issued by the Township Council of the Township of Marlboro where the development may require the expenditure of funds by the Council or where the development requires any other action by the Township Council.
G. The Planning Board and the Board of Adjustment are authorized to retain such experts as are required to assist them in ascertaining the costs of such improvements and the developers pro rata share thereof. The developer shall pay the costs for the services of the experts and shall deposit those costs with the Township.
H. Any money received by the Township for off-tract improvements to be constructed or installed by the Township pursuant to the provisions of this section shall be deposited in a suitable depository therefor and shall be used only for the improvements for which they are deposited or improvements satisfying the same purpose. If construction of improvements for which the Township is responsible has not commenced within 10 years from the date of deposit, the amount deposited, together with any interest thereon, shall be returned to the developer or his successor in interest.
Any project proposed under a permitted form of planned development shall follow the appropriate zoning criteria of this chapter and the applicable subdivision and site plan criteria. Prior to approval of any planned development, the approving authority shall find the following facts and conclusions:
A. All planned developments shall be designed in accordance with the specific planned development provisions of this chapter. The planned development provisions shall supersede any conflicting portions of this chapter to the extent of such inconsistencies.
B. Proposals for maintenance and conservation of the common open space proposed to be handled by a private agency shall be reliable and shall be established in accordance with the homeowners' association provisions of this chapter. Also, the amount, location and purpose of the common open space shall be adequate for the use intended.
C. The physical design of the proposed development for public services, control over vehicular and pedestrian traffic and the amenities of light and air, recreation and visual enjoyment shall be adequate and comply with appropriate portions of the Master Plan.
D. The proposed planned development will not have an unreasonably adverse impact upon the area in which it is proposed to be established.
E. In the case of a proposed development which contemplates construction over a period of years, the terms and conditions intended to protect the interests of the public and of the residents, occupants and owners of the proposed development in the total completion of the development shall be adequate.
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.
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.
[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:
(1) The location of all existing underground utilities within the easement; and
(2) Any alteration to the existing grade of the property within the easement which will result from the proposed construction.
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.

(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.
