The purpose of this article is to ensure that development and use of property are functional and attractive, are assets to the Borough, and minimize adverse impacts upon the site and surrounding neighborhood.
[Amended 9-23-2014 by Ord. No. 2014-17; 5-14-2019 by Ord. No. 2019-05]
Except as preempted by Residential Site Improvement Standards (RSIS), site design standards under Article IX shall be applicable to all site plans, subdivisions and conditional uses. Departure from such standards shall be governed by N.J.S.A. 40:55D-51.
A. 
Design of the development shall take into consideration all existing local and regional plans for the surrounding community.
B. 
Development of the site shall be based on an analysis of the site. To the maximum extent practicable, development shall be located to preserve the natural features of the site, to avoid areas of environmental sensitivity, and to minimize negative impacts and alteration of natural features.
C. 
Prior to submitting an application for consideration of a zoning permit which involves construction of a structure below grade, the applicant shall complete a test pit to determine the seasonal high groundwater table on said property within the area of improvement. Upon determining the seasonal high groundwater table elevation, the lowest portion of the proposed finished floor shall be set a minimum of 18 vertical inches higher than the seasonal high groundwater elevation. The test pit to determine the seasonal high groundwater table elevation shall be conducted in the presence of a Borough representative to confirm the elevation of the seasonal high groundwater demarcation.

Editor's Note: This ordinance also provided for the redesignation of former Subsections C through F as Subsections D through G, respectively.
D. 
The following specific areas shall be preserved as undeveloped open space to the extent consistent with the reasonable utilization of land, and in accordance with applicable or local regulations:
(1) 
Unique and/or fragile areas, including wetlands as defined in Section 404 (per Federal Water Pollution Control Act Amendments of 1972, and delineated on wetlands maps prepared by the U.S. Fish and Wildlife Service, field verified by on-site inspection);
(2) 
Significant trees or stands of trees, defined as the largest known individual trees of each species in the state, large trees approaching the diameter of the known largest tree, or species or clumps of trees that are rare to the area or of particular horticultural or landscape value;
(3) 
Lands in the floodplain, as defined by state or local regulations; and
(4) 
All proposed activities on areas of steep slopes shall be in accordance with § 135-93.1, entitled "Steep slope protection."
[Amended 7-10-2007 by Ord. No. 2007-20]
E. 
The development shall be laid out to avoid adversely affecting groundwater and aquifer recharge; to reduce cut and fill; to avoid unnecessary impervious cover; to prevent flooding; to provide adequate access to lots and sites; and to mitigate adverse effects of shadow, lighting, noise, odor, traffic, drainage, utilities, and lack of air on neighboring properties.
F. 
The developer shall eliminate or provide adequate safeguards in his plan against hazards that would impair life, health or property due to flood, fire and disease.
G. 
The developer must comply with all technical standards and specifications stated in this chapter and in any published standards and specifications addendum or manual which is adopted by resolution of the Board of Commissioners. The above-stated requirements as well as those of other bona fide professional or government organizations whose technical specifications or standards are referred to in this chapter and/or the addendum or manual adopted by the Borough shall be considered to have the same effect of law as if they were part of this chapter. The Borough Engineer shall be the final authority regarding any interpretation of these standards and specifications and shall also approve the design and specifications of any items of construction that a developer is required to or wishes to construct, if not otherwise covered by this chapter or addenda or manuals.
If the Master Plan or the Official Map provides for the reservation of designated walkways or public areas within the proposed development, before approving a subdivision or site plan, the Planning Board may further require that such streets, ways, basins, or areas be shown on the plat in locations and sizes suitable to their intended uses. The Planning Board may reserve the location and extent of such streets, ways, basins or areas shown on the plat for a period of one year after the approval of the final plat or for such further time as may be agreed to by the developer. Unless during such period or extension thereof the Borough shall have entered into a contract to purchase or institute condemnation proceeding according to law for a fee or a lesser interest in the land comprising such streets, ways, basins or areas, the developer shall not be bound by such reservations shown on the plat and may proceed to use such land for private use in accordance with applicable development regulations. The provisions of this section shall not apply to the street and roads, flood control basins or public drainageways necessitated by the subdivision or land development and required for final approval.
A. 
Block length. Blocks shall not be less than 290 feet nor more than 1,300 feet long. Crosswalks up to 10 feet wide may be required for blocks more than 600 feet long.
B. 
Block width. Blocks shall be wide enough for two tiers of lots.
C. 
Through blocks. Double frontage lots are to be avoided and generally will not be permitted unless the lots are a minimum of 200 feet deep. However, where rear yards abut connector streets and the lots are entirely served by a separate local service or neighborhood feeder street, use of double frontage may be required.
D. 
Lot lines. Lot lines shall be at right angles to street lines or radial thereto wherever practicable.
E. 
House numbers. House numbers shall be assigned to each lot by the Borough Assessor.
F. 
Lot sizes. Minimum lot area and dimensions shall be governed by the Zoning Ordinance.[1]
[1]
Editor's Note: See Articles IV and V of this chapter for minimum lot area and dimensions.
G. 
Frontage. All lots shall have frontage on a street conforming with the design standards contained herein, and improved in accordance with Borough specifications.
H. 
Yard orientation. In order to maintain privacy and the character of existing neighborhoods, lots shall be oriented so that side yards adjoin other side yards, and rear yards adjoin other rear yards. In the case of corner lots, the one rear yard of the lot is allowed to adjoin the side yard of an adjacent lot.
[Added 3-8-1994 by Ord. No. 1692 A]
A. 
Residential lots should front on local service or feeder streets, not on connector streets.
B. 
Every lot shall have sufficient access to it for emergency vehicles as well as for those needing access to the property in its intended use.
C. 
The placement of units in residential developments shall take into consideration topography, privacy, building height, orientation, drainage, and aesthetics.
D. 
Buildings shall be spaced so that adequate privacy is provided for units.
E. 
Residential developments with three or more units per building or structure shall provide a centralized and screened solid waste and recycling management facility.
[Added 7-23-2002 by Ord. No. 1825, effective 9-15-2002]
Commercial and other developments shall be designed according to the same principles governing the design of residential developments; namely, buildings shall be located according to topography, with environmentally sensitive areas avoided to the maximum extent practicable; factors such as drainage, noise, odor, and surrounding land uses considered in siting buildings; sufficient access shall be provided; and adverse impacts buffered.
A. 
Road system and parking areas shall be designed to permit the safe, efficient and orderly movement of traffic; to meet, but not to exceed, the needs of the present and future population served; to have a simple and logical pattern; to provide for safe, efficient and orderly and adequate on-site or off-site parking for residents, customers and visitors; to provide safe, efficient and orderly off-street loading and unloading, including the movement of goods and vehicles; to respect natural features and topography; and to present an attractive streetscape per § 135-85.
[Amended 3-8-1994 by Ord. No. 1692 A]
B. 
In residential areas, the road system shall be designed to serve the needs of the neighborhood and to discourage use by through traffic.
C. 
The pedestrian system shall be located as required for safety per § 135-85. Sidewalks shall be placed parallel to the street, with exceptions permitted to preserve natural features or to provide visual interest.
D. 
Bikeways and walkways are encouraged as a means to facilitate circulation among and between buildings and other properties.
A. 
Function and materials. Buffering shall provide a year-round visual screen in order to minimize adverse impacts. It may consist of fencing, evergreens, berms, rocks, boulders, mounds, or combinations thereof to achieve the same objectives.
B. 
When required. Every development shall provide sufficient buffering when topographical or other barriers do not provide reasonable screening and when the Planning Board determines that there is a need to shield neighboring properties from any adverse external effects of a development or to shield the development from negative impacts of adjacent uses such as streets or railroads. In high-density developments, when building design and siting do not provide privacy, the Planning Board may require landscaping, fences, or walls to screen dwelling units for privacy. Buffers shall be measured from side and rear property lines, excluding driveways.
C. 
Amount required.
(1) 
Where residential and nonresidential uses abut each other, a buffer strip of six feet shall be required between such uses. Such buffer shall be opaque.
(2) 
Parking lots, garbage collection and utility areas, and loading and unloading areas should be screened around their perimeters by buffer strips, preferably a minimum of five feet wide.
D. 
Design. Arrangements of plantings in buffers shall provide maximum protection to adjacent properties and avoid damage to existing plant material. Possible arrangements include planting in parallel, serpentine, or broken rows. If planted berms are used, the minimum side slope shall be 2:1.
E. 
Planting specifications. Plant materials shall be sufficiently large and planted in such a fashion that a year-round screen at least eight feet in height shall be produced within three growing seasons. All plantings shall be installed according to accepted horticultural standards.
F. 
Maintenance. Plantings shall be watered regularly and in a manner appropriate for the specific plant species through the first growing season, and dead and dying plants shall be replaced by the applicant during the next planting season. No buildings, structures, storage of materials, or parking shall be permitted within the buffer area; buffer areas shall be maintained and kept free of all debris, rubbish, weeds and tall grass. Failure to maintain the approved buffer shall be considered an unapproved change in the site plan and shall therefore be a violation of this chapter to be enforced under the penalty sections of this chapter.[1]
[1]
Editor's Note: See Art. XVI of this chapter.
A. 
Purpose.
(1) 
Landscaping shall be provided as part of site plan and subdivision design. It shall be conceived in a total pattern throughout the site, integrating the various elements of site design, preserving and enhancing the particular identity of the site, and creating a pleasing site character.
(2) 
Landscaping may include plant materials such as trees, shrubs, ground covers, perennials, and annuals, and other materials such as rocks, water, sculpture, art, walls, fences, paving materials, lighting for aesthetics and street furniture.
(3) 
Landscaping shall be planned in such a way that the site requires as little use of potable water as possible to insure the survival of the plants. Water conservation is a critical purpose of this section.
B. 
Landscape plan. A landscape plan prepared by a certified landscape architect shall be submitted with each site plan and major subdivision application, unless an exception is granted pursuant to § 135-68B of this chapter. The plan shall identify existing and proposed trees, shrubs, and ground covers; existing landscaping to be removed; natural features such as rock outcropping; and other landscaping elements. The plan shall show where they are or will be located and planting and/or construction details. Where existing plantings are to be retained, the application shall include in the plan's proposed methods of protecting them during construction. The landscape plan shall also address landscape maintenance requirements.
C. 
Site protection and general planting requirements.
(1) 
Topsoil preservation. Topsoil moved during the course of construction shall be redistributed on all regraded surfaces so as to provide at least four inches of even cover to all disturbed areas of the development and shall be stabilized by seeding or planting.
(2) 
Removal of debris. All stumps and other tree parts, litter, brush, weeds, excess or scrap building materials or other debris shall be removed from the site and disposed of in accordance with the law. No tree stumps, or portions of tree trunks or limbs shall be buried anywhere in the development. All dead or dying trees, standing or fallen, shall be removed from the site. If trees and limbs are reduced to chips, they may be used as mulch in landscaped areas, subject to approval by the Borough Engineer.
(3) 
Protection of existing plantings. Maximum effort should be made to save mature trees, including those trees with a diameter of 10 inches or more. No material or temporary soil deposits shall be placed within four feet of shrubs or 10 feet of trees designated on the landscape plan to be retained. Protective barriers shall be installed around each plant or group of plants that are to remain on site. Barriers shall not be supported by the plants they are protecting, but shall be self-supporting. They shall be a minimum of four feet high and constructed of a durable material that will last until construction is completed. Snow fences and silt fences are examples of acceptable barriers.
[Amended 6-24-2008 by Ord. No. 2008-15]
(3.1) 
On-site compensatory tree planting. In the event that it is impractical or would cause undue hardship in the opinion of the Planning Board or Zoning Board of Adjustment that an existing tree with a diameter of 10 inches or more be retained, compensatory planting shall be provided according to the following schedule and standards:
[Added 6-24-2008 by Ord. No. 2008-15]
Diameter of Tree Removed
(inches)
Number of Replacements Per Tree Removed
10 to 18

Greater than 18 to 24
2
Greater than 24 to 30
3
Greater than 30 to 36
4
Greater than 36 to 40
5
Greater than 40

(a) 
Replacement trees shall be nursery grown and comply with American Association of Nurserymen standards for nursery stock and shall be between 2.5 inches and 3.5 inches in caliper.
(b) 
Replacement trees may be used anywhere on site, unless prohibited by law, and shall be planted in accordance with the standards of the American Association of Nurserymen. However, if one or more of the following conditions exist, some or all of the replacement trees may be planted off site:
[Amended 9-23-2014 by Ord. No. 2014-17]
[1] 
The site in question cannot physically accommodate the total replacement amount of trees, and the applicant contributes an amount equal to the calculated monetary value of nonreplaced trees to the Tree Escrow Fund; or
[2] 
The Shade Tree Commission and applicant agree in writing that the applicant shall make payment to the Tree Escrow Fund based upon a fee schedule which shall be set by a resolution of the Board of Commissioners each year.
(c) 
All trees shall be guaranteed for a minimum of one year from the time of planting by the applicant against death and disease.
(d) 
In the event that it is impractical to install replacement trees immediately due to planting hazards or species availability, a bond covering the total cost of the plant material and installation shall be posted with the Borough.
(e) 
In the event it is impractical to provide the required number of replacement trees on the subject site, fewer, however, larger, more valuable replacement trees shall be installed on the site, with an aggregate cost as installed not less than the estimated aggregate cost of the required number of replacement trees. Alternatively, the applicant and the Shade Tree Commission may agree in writing that the applicant make payment to the Tree Escrow Fund to cover the cost of planting trees elsewhere in the Borough. Each year the Board of Commissioners shall, by resolution, establish a fee schedule.
[Amended 9-23-2014 by Ord. No. 2014-17]
(4) 
Slope plantings. Landscaping of all cuts and fills and/or terraces shall be sufficient to prevent erosion, and all roadway slopes steeper than one foot vertically to three feet horizontally shall be planted with ground cover appropriate for the purpose and for soil conditions, water availability, and environment.
(5) 
Additional landscaping. In residential developments, besides the screening and street trees required, additional plantings or landscaping elements may be required throughout the subdivision where necessary for climate control, privacy, or other reasons in accordance with the landscape plan approved by the Planning Board. In nonresidential developments, all areas of the site not occupied by buildings and required improvements shall be landscaped by the planting of grass or other ground cover, shrubs, and trees as part of the landscape plan approved by the Planning Board.
(6) 
Planting specification. Deciduous trees shall be at least 2 1/2 inches caliper at planting and should be balled and burlapped. Size of evergreens should be four feet tall and shrubs two feet tall at planting but may be allowed to vary depending on setting and type of shrub. Only nursery-grown plant materials shall be acceptable, and trees, shrubs, and ground cover shall be planted according to accepted horticultural standards. Dead and dying plants shall be replaced by the developer during the following planting season.
(7) 
Plant species. The plant species selected should be hardy for this portion of New Jersey and appropriate in terms of function and size. They should be of a type that requires the least amount of watering for survival to meet the water conservation purposes of this section.
(8) 
Maintenance. The maintenance standards of § 135-83 shall be followed.
D. 
Shade trees.
(1) 
Location. Applicants shall provide shade trees on both sides of all streets. The trees shall be planted at a minimum of one tree per each 25 feet of frontage unless otherwise determined by the Haddonfield Shade Tree Commission. Tree location, landscape design, and spacing as determined by the Shade Tree Commission shall be included as part of the landscape plan approved by the Planning or Zoning Board.
[Amended 7-23-2002 by Ord. No. 1825, effective 9-15-2002]
(2) 
Tree type. Tree type may vary depending on overall effect desired, but as a general rule, all trees on a street shall be the same kind except to achieve special effects. Selection of tree types shall be in accordance with the Shade Tree Commission's approved plan and be approved by the Planning Board.
(3) 
Planting specifications. All trees shall have a caliper of at least 2 1/2 inches and be nursery grown, of substantially uniform size and shape, and have straight trunks. Trees shall be properly planted and staked and provision made by the applicant for regular watering and maintenance until they are established. Dead and dying trees shall be replaced by the applicant during the next planting season.
(4) 
Applicants are encouraged to consult with the Shade Tree Commission early in plan development to ensure that shade tree plans are compatible with Borough goals and requirements.
E. 
Paving materials.
(1) 
Design and choice of paving materials used in pedestrian areas shall consider such factors as function, climate, characteristics of users, availability, cost, maintenance, glare, drainage, noise, appearance and compatibility with surroundings.
(2) 
Acceptable materials shall include, but are not limited to, concrete, brick, cement pavers, asphalt and stone.
F. 
Walls and fences.
(1) 
Walls and fences shall be erected where required for privacy, screening, separation, security, erosion control, or to serve other necessary and reasonable functions.
(2) 
The design and materials used shall be functional and compatible with existing and proposed site architecture.
(3)

(2) 
The different street furniture components shall be compatible in form, material and finish. Design and materials shall be coordinated with existing and proposed site architecture. Selection of street furniture shall take into consideration function, durability, maintenance, and long-term cost.
A. 
Streets shall be classified in a hierarchical system as follows:
(1) 
Local service streets: streets providing direct access to residential structures, and intended primarily to serve only the properties along them.
(2) 
Feeder streets: streets connecting local service streets; providing access to community facilities and connector streets.
(3) 
Connector streets: streets which provide the principal connections among communities, and to regional highways, and which provide the principal means of internal traffic movement.
(4) 
Cul-de-sac: a street with one end open for vehicular and pedestrian access and the other end terminating in a vehicular turnaround.

A. 
Scope, purpose and applicability.
(1) 
Policy statement. Stormwater systems shall emphasize a natural as opposed to an engineered approach. Flood control, groundwater recharge, and pollutant reduction through nonstructural or low-impact techniques shall be explored before relying on engineered or "structural" best management practices (BMPs). Structural BMPs should be integrated with nonstructural stormwater management strategies and proper maintenance plans. Nonstructural strategies include both environmentally sensitive site design and source controls that prevent pollutants from being placed on the site or from being exposed to stormwater. Source control plans should be developed based upon physical site conditions and the origin, nature, and the anticipated quantity or amount of potential pollutants. Multiple stormwater management BMPs may be necessary to achieve the established performance standards for water quality, quantity, and groundwater recharge.
(2) 
Purpose. It is the purpose of this section to establish minimum stormwater management requirements and controls for all development, with the exception of additions and renovations to single-family homes that do not increase existing impervious coverage by more than 20%, which conform to the Land Development Ordinance of the Borough of Haddonfield.
[Amended 5-9-2017 by Ord. No. 2017-06]

(b) 
This section shall also be applicable to all projects undertaken by the Borough of Haddonfield.
(c) 
All new homes and commercial buildings requiring a building permit issued by the Borough of Haddonfield.
(d) 
All additions and renovations that increase existing impervious coverage by more than 20%.
[Added 5-9-2017 by Ord. No. 2017-06]

[b] 
Examples of grates subject to this standard include grates in grate inlets, the grate portion (non-curb-opening portion) of combination inlets, grates on storm sewer manholes, ditch grates, trench grates, and grates of spacer bars in slotted drains. Examples of ground surfaces include surfaces of roads (including bridges), driveways, parking areas, bikeways, plazas, sidewalks, lawns, fields, open channels, and stormwater basin floors.
[2] 
Whenever design engineers use a curb-opening inlet, the clear space in that curb opening (or each individual clear space, if the curb opening has two or more clear spaces) shall have an area of no more than seven square inches, or be no greater than two inches across the smallest dimension.
[3] 
This standard does not apply:
[a] 
Where the review agency determines that this standard would cause inadequate hydraulic performance that could not practicably be overcome by using additional or larger storm drain inlets that meet these standards;
[b] 
Where flows from the water quality design storm are conveyed through any device (e.g., end-of-pipe netting facility, manufactured treatment device, or a catch basin hood) that is designed, at a minimum, to prevent delivery of all solid and floatable materials that could not pass through one of the following:
[i] 
A rectangular space 4 5/8 inches long and 1 1/2 inches wide (this option does not apply for outfall netting facilities); or
[ii] 
A bar screen having a bar spacing of 0.5 inch.
[c] 
Where flows are conveyed through a trash rack that has parallel bars with one-inch spacing between the bars, to the elevation of the water quality design storm; or
[d] 
Where the New Jersey Department of Environmental Protection determines, pursuant to the New Jersey Register of Historic Places Rules at N.J.A.C. 7:4-7.2(c), that action to meet this standard is an undertaking that constitutes an encroachment or will damage or destroy the New Jersey Register listed historic property.
(d) 
Any land area used as a nonstructural stormwater management measure to meet the performance standards in Subsection D(6) and D(7) shall be dedicated to a government agency, subjected to a conservation restriction filed with the appropriate County Clerk's office, or subject to an approved equivalent restriction that ensures that the measure or an equivalent stormwater management measure approved by the reviewing agency is maintained in perpetuity.
(e)

(6) 
Erosion control, groundwater recharge and runoff quantity standards.
(a) 
Erosion Control. The minimum design and performance standards for soil erosion control are as follows:
[1] 
The minimum design and performance standards for erosion control are those established under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq. and implementing rules.
[2] 
Soil erosion and sediment controls shall be required for all development. For development not covered under this section, soil erosion and sediment control shall be at the direction of the Director of Community Development.
(b) 
Groundwater recharge. The minimum design and performance standards for groundwater recharge for all development are as follows:
[1] 
The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at Subsection E, either:
[a] 
Demonstrate through hydrologic and hydraulic analysis that the site and its stormwater management measures maintain 100% of the average annual preconstruction groundwater recharge volume for the site; or
[b] 
Demonstrate through hydrologic and hydraulic analysis that the increase of stormwater runoff volume from preconstruction to postconstruction for the two-year storm is infiltrated.
[2] 
This groundwater recharge requirement does not apply to the following projects:
[a] 
Stormwater from areas of high pollutant loading. High pollutant loading areas are areas in industrial and commercial developments where solvents and/or petroleum products are loaded/unloaded, stored, or applied, areas where pesticides are loaded/unloaded or stored; areas where hazardous materials are expected to be present in greater than "reportable quantities" as defined by the United States Environmental Protection Agency (EPA) at 40 CFR 302.4; areas where recharge would be inconsistent with a Department-approved remedial action work plan or landfill closure plan and areas with high risks for spills of toxic materials, such as gas stations and vehicle maintenance facilities; and
[b] 
Industrial stormwater exposed to source material. "Source material" means any material(s) or machinery, located at an industrial facility, that is directly or indirectly related to process, manufacturing or other industrial activities, which could be a source of pollutants in any industrial stormwater discharge to groundwater. Source materials include, but are not limited to, raw materials; intermediate products; final products; waste materials; by-products; industrial machinery and fuels, and lubricants, solvents, and detergents that are related to process, manufacturing, or other industrial activities that are exposed to stormwater.
[3] 
The design engineer shall assess the hydraulic impact on the groundwater table and design the site so as to avoid adverse hydraulic impacts. Potential adverse hydraulic impacts include, but are not limited to, exacerbating a naturally or seasonally high water table so as to cause surficial ponding, flooding of basements, or interference with the proper operation of subsurface sewage disposal systems and other subsurface structures in the vicinity or downgradient of the groundwater recharge area.
[4] 
The design of all proposed infiltration measures shall be based on on-site boring logs or soil pit profiles as witnessed by the Borough Engineer. The number and location of required soil borings or soil pits shall be reviewed by the Borough Engineer and should be based on the suitability and distribution of soils present at the location of the proposed infiltration measure. The results of all soil borings, including the location of the boring and all elevation data, shall be included in a separate soils report or included on the project plans.
(c) 
Runoff quantity standards. In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at Subsection E, complete one of the following:
[1] 
Demonstrate through hydrologic and hydraulic analysis that for stormwater leaving the site, postconstruction runoff hydrographs for the two-, ten-, and one-hundred-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 one-hundred-year storm events and that the increased volume or change in timing of stormwater runoff will not increase flood damage at or downstream of the site. This analysis shall include the analysis of impacts of existing land uses and projected land uses assuming full development under existing zoning and land use ordinances in the drainage area;
[3] 
Design stormwater management measures so that the postconstruction peak runoff rates for the two-, ten-, and one-hundred-year storm events are 50%, 75%, and 80%, respectively, of the preconstruction peak runoff rates. The percentages apply only to the postconstruction stormwater runoff that is attributable to the portion of the site on which the proposed development or project is to be constructed. The percentages shall not be applied to postconstruction stormwater runoff into tidal flood hazard areas if the increased volume of stormwater runoff will not increase flood damages below the point of discharge; or
[4] 
In tidal flood hazard areas, or as directed by the Director of Community Development, stormwater runoff quantity analysis shall be in accordance with Subsection D(6)(c)[3] above.
(7) 
Stormwater runoff quality standards.
(a) 
Stormwater management measures shall be designed to reduce the postconstruction load of total suspended solids (TSS) in stormwater runoff by 80% of the anticipated load from the developed site, expressed as an annual average. Stormwater management measures shall only be required for water quality control if an additional 1/4 acre of impervious surface is being proposed on a development site. 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 Pollution Discharge Elimination System (NJPDES) rules, N.J.A.C. 7:14A, or in a discharge specifically exempt under a NJPDES permit from this requirement. 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 1. The calculation of the volume of runoff may take into account the implementation of nonstructural and structural stormwater management measures.

For purposes of TSS reduction calculations, Table 2 below presents the presumed removal rates for certain BMPs designed in accordance with the New Jersey Stormwater Best Management Practices Manual. The most recent version of the BMP Manual may be obtained from New Jersey Department of Environmental Protection. TSS reduction shall be calculated based on the removal rates for the BMPs in Table 2 below. Alternative removal rates and methods of calculating removal rates may be used if the design engineer provides documentation demonstrating the capability of these alternative rates and methods to the review agency. A copy of any approved alternative rate or method of calculating the removal rate shall be provided to the Department of Environmental Protection.
(c) 
If more than one BMP in series is necessary to achieve the required eighty-percent TSS reduction for a site, the applicant shall utilize the following formula to calculate TSS reduction:
R = A + B - (AXB)/100
Where
R = total TSS percent load removal from application of both BMPs
A = TSS percent removal rate applicable to the first BMP
B = TSS percent removal rate applicable to the second BMP

(e) 
Stormwater management measures shall also be designed to reduce, to the maximum extent feasible, the postconstruction 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 nonstructural strategies and structural measures that optimize nutrient removal while still achieving the performance standards in Subsection D(6) and D(7).
(f) 
Additional information and examples are available from the New Jersey Department of Environmental Protection.
(g) 
In accordance with the definition of FW1 at N.J.A.C. 7:9B-1.4, stormwater management measures shall be designed to prevent any increase in stormwater runoff to waters classified as FW1.
(h) 
Special water resource protection areas shall be established along all waters designated Category One at N.J.A.C. 7:9B, and perennial or intermittent streams that drain into or upstream of the Category One waters as shown on the USGS Quadrangle Maps or in the County Soil Surveys, within the associated HUC14 drainage area. These areas shall be established for the protection of water quality, aesthetic value, exceptional ecological significance, exceptional recreational significance, exceptional water supply significance, and exceptional fisheries significance of those established Category One waters. These areas shall be designated and protected as follows:
[1] 
The applicant shall preserve and maintain a special water resource protection area in accordance with one of the following:
[a] 
A three-hundred-foot special water resource protection area shall be provided on each side of the waterway, measured perpendicular to the waterway from the top of the bank outwards or from the center line of the waterway where the bank is not defined, consisting of existing vegetation or vegetation allowed to follow natural succession.
[b] 
Encroachment within the designated special water resource protection area shall only be allowed where previous development or disturbance has occurred (for example, active agricultural use, parking area or maintained lawn area). The encroachment shall only be allowed where applicant demonstrates that the functional value and overall condition of the special water resource protection area will be maintained to the maximum extent practicable. In no case shall the remaining special water resource protection area be reduced to less than 150 feet as measured perpendicular to the top of bank of the waterway or center line of the waterway where the bank is undefined. All encroachments proposed shall be subject to review and approval by the Department.
[2] 
All stormwater shall be discharged outside of and flow through the special water resource protection area and shall comply with the Standard for Off-Site Stability in the Standards for Soil Erosion and Sediment Control in New Jersey, established under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq.
[3] 
If stormwater discharged outside of and flowing through the special water resource protection area cannot comply with the Standard for Off-Site Stability in the Standards for Soil Erosion and Sediment Control in New Jersey, established under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq., then the stabilization measures in accordance with the requirements of the above standards may be placed within the special water resource protection area, provided that:
[a] 
Stabilization measures shall not be placed within 150 feet of the Category One waterway;
[b] 
Stormwater associated with discharges allowed by this subsection shall achieve a ninety-five-percent TSS postconstruction removal rate;
[c]

The encroachment shall only be allowed where the applicant demonstrates that the functional value and overall condition of the special water resource protection area will be maintained to the maximum extent practicable;
[e] 
A conceptual project design meeting shall be held with the appropriate Department staff and Soil Conservation District staff to identify necessary stabilization measures; and
[f] 
All encroachments proposed under this section shall be subject to review and approval by the Department.
[4] 
A stream corridor protection plan may be developed by a regional stormwater management planning committee as an element of a regional stormwater management plan, or by a municipality through an adopted municipal stormwater management plan. If a stream corridor protection plan for a waterway subject to Subsection D(7)(h) has been approved by the Department, then the provisions of the plan shall be the applicable special water resource protection area requirements for that waterway. A stream corridor protection plan for a waterway shall maintain or enhance the current functional value and overall condition of the special water resource protection area. In no case shall a stream corridor protection plan allow the reduction of the Special Water Resource Protection Area to less than 150 feet as measured perpendicular to the waterway subject to this subsection.
E. 
Calculation of stormwater runoff and groundwater recharge.
(1) 
Stormwater runoff shall be calculated in accordance with the following:
(a) 
The design engineer shall calculate runoff using one of the following methods:
[1] 
The USDA Natural Resources Conservation Service (NRCS) methodology, including the NRCS Runoff Equation and Dimensionless Unit Hydrograph, as described in the NRCS National Engineering Handbook Section 4 — Hydrology and Technical Release 55 — Urban Hydrology for Small Watersheds; or
[2] 
The Rational Method for peak flow and the Modified Rational Method for hydrograph computations.
[3] 
As directed by the Borough Engineer, the Rational Method Triangular Hydrography Approximation may be used to calculate the volume of stormwater runoff for sites less than one acre.
(b) 
For the purpose of calculating runoff coefficients and groundwater recharge, there is a presumption that the preconstruction condition of a site is a wooded land use with good hydrologic condition, unless otherwise directed by the Borough Engineer. The term "runoff coefficient" applies to both the NRCS methodology and the Rational and Modified Rational Methods. If more than one land cover has existed on the site during the five years immediately prior to the time of application, the land cover with the lowest runoff potential shall be used for the computations, unless otherwise directed by the Borough Engineer. In addition, there is the presumption that the site is in good hydrologic condition (if the land use type is pasture, lawn, or park), with good cover (if the land use type is woods), or with good hydrologic condition and conservation treatment (if the land use type is cultivation).
(c) 
In computing preconstruction stormwater runoff, the design engineer shall account for all significant land features and structures, such as ponds, wetlands, depressions, hedgerows, or culverts, that may reduce preconstruction stormwater runoff rates and volumes.
(d) 
In computing stormwater runoff from all design storms, the design engineer shall consider the relative stormwater runoff rates and/or volumes of pervious and impervious surfaces separately to accurately compute the rates and volume of stormwater runoff from the site. To calculate runoff from unconnected impervious cover, urban impervious area modifications as described in the NRCS Technical Release 55 - Urban Hydrology for Small Watersheds and other methods may be employed.
(e) 
If the invert of the outlet structure of a stormwater management measure is below the flood hazard design flood elevation as defined at N.J.A.C. 7:13, the design engineer shall take into account the effects of tailwater in the design of structural stormwater management measures.
(2) 
Groundwater recharge may be calculated in accordance with the following:
(a) 
The New Jersey Geological Survey Report GSR-32 A Method for Evaluating Ground-Water Recharge Areas in New Jersey, incorporated herein by reference as amended and supplemented. Information regarding the methodology is available from the New Jersey Department of Environmental Protection.

A. 
Statement of purpose.
(1) 
It is the express purpose of this section to provide special qualitative and quantitative development controls for all lands located within the Borough that have present within their boundaries topographical conditions, hereinafter defined as "steep slopes."
(2) 
These special development controls are provided in recognition of the potentially negative impacts of construction in steep slope areas in the form of erosion, siltation, excessive removal of vegetation and soil, flooding, soil slippage, water runoff and destruction of unique land forms and scenic vistas. It is further the purpose of this section to encourage good land use planning and design, maximize optimal use of the natural terrain and maintain ridgelines and scenic vistas intact.
(3) 
Effective and reasonable application of these regulations will protect the health, safety and welfare of the citizens of the Borough, as well as limit the adverse impact on adjoining and/or downstream properties.
(4) 
This chapter is further promulgated to provide a functional land use design and control mechanism that will augment the basic land use controls of this chapter and the administrative implementation devices contained within the Land Development Ordinance.
B. 
Applicability. The requirements, guidelines and controls promulgated under this chapter shall be applicable to all properties within all zone districts situated in the Borough in their existing physical state or condition as of the date of the passage of this chapter.
C. 
Definition. A steep slope is defined as an area of land where the slope exceeds 15%. Determination of slope shall be by measurement of run perpendicular to the contours from the top of the slope to the bottom of the slope for a minimum horizontal interval of 100 feet.
D.

A. 
For all lots with proposed disturbances, an individual lot grading plan shall be approved by the Borough Engineer prior to the issuance of a building permit. All lot grading plans shall be prepared by an appropriate professional and shall include, but not be limited to, the following:
(1) 
Existing and proposed contours on the property and within 25 feet of all property lines.
(2) 
Limit of soil disturbance.
(3) 
Appropriate construction details.
(4) 
Soil erosion, sedimentation control measures and drainage calculations.
(5) 
Where required by the Community Development Director, existing and proposed stormwater control measures.
B. 
The design standards for lot grading plans shall be pursuant to the following standards:
(1) 
No soil shall be excavated, removed, deposited or disturbed except as a result of and in accordance with a lot grading plan approved under the terms of this chapter.
(2) 
Proposed disturbance of soil shall be minimized, for purposes consistent with the intent of this chapter, and it shall be executed in a manner that will not cause erosion or other unstable conditions.
(3) 
Provision shall be made for the proper disposition of surface water runoff so that it will not increase unstable conditions. Appropriate storm drainage improvements shall be provided for all downstream properties.
(4) 
Provision shall be made for any structure or protective measures that proposed slopes may require for the protection of the public safety, including but not limited to retaining walls, guide rails, headwalls and fences.
(5) 
Any proposed building or structure or attendant protective measures will not impede the flow of surface water through any watercourse. Only a nominal increase in water surface elevation and velocities will be allowed due to construction.
(6) 
Any proposed vehicular facilities, including roads, drives or parking areas, shall be so designed that any land disturbances shall not cause excessive erosion. Both the vertical and horizontal alignment of vehicular facilities shall be so designed that hazardous circulation conditions will not be created.
(7) 
Final grades of the proposed driveway shall not exceed 10% without approval by the Borough Engineer.
(8) 
Any fill placed on the lot shall be properly stabilized and, when found necessary depending upon existing slopes and soil types, supported by retaining walls or other appropriate structures as approved by the Borough Engineer.
(9) 
All cuts shall be supported by retaining walls or other appropriate retaining structures when, depending upon the nature of the soil characteristics, such structures are found necessary by the Borough Engineer in order to prevent erosion.
(10) 
There shall be no alternation of site elevations within five feet of an adjoining property without approval of the Community Development Director.
(11) 
Changes in grade shall not exceed a slope of three to one unless supported by retaining walls.
(12) 
No retaining wall on a residential site shall exceed four feet in height, and there shall be at least 10 feet between stepped retaining walls. All retaining walls greater than four feet in height require a certification by a professional engineer that the wall was constructed in accordance with approved plans.
C. 
For all lot grading plans submitted to and approved by the Borough Engineer, an as-built plan shall also be submitted for final review and approval by the Borough Engineer or Community Development Director.
D. 
The fee for submission of the grading plan shall be $50. The escrow amount for review and inspection of the grading plan shall be $1,500.
E. 
Exemptions:
(1) 
The Zoning Official or Construction Official shall have the right to waive the requirements of §§ 135-93.1 and 135-93.2 only based on the description of work.

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