Borough of South River, NJ Design Standards

The arrangement of streets shall be such as to provide for the extension of existing streets where appropriate.

In general, local residential streets shall be designed to discourage through traffic, and proposed larger traffic generators shall not be permitted through local residential streets. Streets and roadways shall be located to blend with the topographic and aesthetic features of the site. Local residential roads shall be curved wherever possible to avoid conformity of lot appearance and to discourage through traffic. The grade of the streets shall run with the topography wherever possible and in a manner that provides most of the lots to be at or above the grade of the road.

If the subdivision or site plan abuts a major arterial road, the proposed plan shall include provisions to minimize the number of curb cuts or entrances onto and exits from same. Wherever possible, reverse frontage streets shall be employed or may be required by the Board.

Streets shall be of sufficient width and of suitable design to accommodate prospective traffic but in all cases shall have a right-of-way width, measured from lot line to lot line, of not less than 50 feet for minor or marginal access streets and not less than 60 feet for collector and arterial streets.

In a subdivision that adjoins or includes an existing street that does not conform to the width designated in the Master Plan, Official Map or as required herein, such additional width shall be dedicated along either or both sides of such street as the Board may determine to be necessary and reasonable.

The width of the right-of-way of internal roads, alleys and serviceways in multifamily, commercial and industrial developments shall be determined on an individual basis and in all cases shall be of sufficient width and of suitable design to comply with all applicable Borough requirements and to safely accommodate the anticipated peak traffic, parking and loading needs and to provide sufficient access and turnaround space for fire-fighting equipment.

Grades for minor residential streets shall not exceed 8% or have a minimum grade of less than 0.75%. Within 50 feet of the intersection of any such street with an arterial street, the maximum grade shall be limited to 2%. For arterial, collector, industrial or commercial roadways, the maximum grade shall be 7%.

(8)

Street intersections shall be as nearly at right angles as is possible and in no case shall be less than 60°. At the street corners, curbs shall be rounded with a curve having a radius of not less than 25 feet.

(9)

A vertical curve of sufficient length shall be provided at all changes of grade of streets to provide moving vehicles with a smooth transition and to allow sufficient sight distance to drivers in order to assure traffic and pedestrian safety.

(10)

Culs-de-sac shall be avoided to the extent feasible. When needed, such streets shall be no longer than 600 feet and shall provide a turnaround at the end with a radius of not less than 60 feet, tangent whenever possible to the right side of the street. Where the street or alley is in excess of 100 feet in length, it shall be subject to a determination by the Board that the design is such that fire-fighting apparatus of the Borough shall not be deprived of ready access to structures served by such cul-de-sac. If a dead-end street is of a temporary nature, a temporary cul-de-sac shall be installed in accordance with the requirements for a permanent cul-de-sac. Future extension of the street shall result in the revision of the right-of-way to the adjoining properties.

(11)

In residential developments, four-way intersections shall be prohibited except where deemed desirable by the Borough.

(12)

Street jogs with center-line offsets of less than 125 feet shall be prohibited.

(13)

Longitudinal changes in direction along a street shall be made by means of a curve with a minimum center-line radius of 150 feet for minor streets and a minimum of 300 feet for arterial or collector roads.

(14)

Where streets have a reverse curve, a tangent of at least 100 feet in length shall be required.

(15)

No street shall have a name which will duplicate or so nearly duplicate as to be confused with the names of existing streets. The continuation of an existing street shall have the same name.

(16)

All intersections shall be provided with sight triangle easements of 90 feet by 90 feet for intersections of minor streets and a triangle with a two-hundred-foot base for collector roads.

(17)

Pavement specifications.

All underground utilities shall be installed prior to the installation of pavement.

All unsuitable materials, such as debris, stumps, loose boulders, soft clay, muck or other materials, shall be removed from the right-of-way limits as may be directed by the Borough Engineer.

All excavation for utilities or for removing unsuitable materials shall be refilled to the proper road grade in twelve-inch maximum lifts with select fill material consisting of an approved sand and gravel material. The select fill shall be compacted to 95% of its modified Proctor density. Where deemed necessary by the Borough Engineer, crushed stone or quarry process stone shall be utilized.

If the road base remains wet for prolonged periods or is unstable as a result of wet conditions, the Borough Engineer may require the installation of subsurface piping to drain the road base.

(e)

Road base course. After the subbase has been thoroughly compacted to 95% of its modified Proctor density and approved by the Borough Engineer, a minimum of six inches of hot bituminous stabilized base course shall be installed in two three-inch lifts in all minor roads in accordance with the latest requirements of the New Jersey State Highway Department Standard Specifications for Road and Bridge Construction. The Borough Engineer may permit installation of one six-inch lift if conditions warrant. The thickness of the base course shall be increased as deemed necessary by the Borough Engineer, depending on anticipated traffic and soils conditions for roads other than minor and local roads. The base course for the entire road or large section thereof shall be installed as soon as possible to afford access to the site and shall be installed prior to issuing certificates of occupancy for any house fronting same.

(f)

Road surface wearing course. The road surface pavement course shall be hot type FABC-1 or SM-1 bituminous concrete surface course and shall be manufactured and installed in accordance with the New Jersey State Highway Department Standard Specifications for Road and Bridge Construction (latest revision). The required minimum thickness shall be 1 1/2 inches for all minor streets with sound and stable base. For collector roads or other streets, the minimum thickness shall be two inches. The wearing surface shall not be permitted to be installed until all major construction is completed, all curbs and sidewalks repaired, all base pavement repairs are made in accordance with the directions of the Borough Engineer, all low spots are brought to grade with leveling wedges, all manhole and inlet castings are grouted and the road is approved for paving by the Borough Engineer. The last two certificates of occupancy shall not be issued until the paving is completed, unless waived by the Borough.

(g)

Development along existing streets. Where existing streets are to be excavated for curbs, utilities extension or other purposes, trenches shall be backfilled, and pavement replacement shall be in accordance with requirements of this Part 1, except where existing pavement is reinforced concrete, in which case the pavement or replacement shall be reinforced concrete in accordance with the requirements of the Borough Engineer. After completion of all pavement excavations, curbing and utility installations in existing streets, the pavement base shall be replaced as specified in this section, and the roadway shall be overlaid with 1 1/2 inches of bituminous concrete surface overlay along the entire frontage to the center line of the roadway if deemed necessary by the Borough Engineer.

Blocks and lots.

Block lengths and widths within the bounding road shall be such as to accommodate the size of lot required in the area by the Zoning Ordinance[1] to provide for convenient access, circulation and safety of street traffic.

Editor's Note: See Ch. 350, Zoning.

Lot dimensions and areas shall not be less than as required by the Zoning Ordinance.

Insofar as it is practical, side lot lines shall be at right angles to straight streets and radial to curved streets. Lot lines shall be regular and straight, except where the outside perimeter lines of the subdivision tract make such an arrangement unfeasible, and shall be free of irregularities and internal jogs, except where actual land conditions necessitate such delineation.

Each lot shall front on an approved street, and before a permit for the erection of any structure on the lot is granted, such street shall be improved or such improvements shall have been assured by means of a performance guarantee.

Where extra width has been provided for the widening of existing streets, lot measurements shall begin at such extra width line, and all setbacks shall be measured from such line.

Intersecting property lines on corner lots adjacent to the street lines shall be rounded with a curve having a radius of no less than 15 feet.

Where there is a question as to the suitability of a lot or lots for their intended use due to factors such as rock formations, flood conditions or similar circumstances, the Borough may, after adequate investigation, withhold approval of such lots.

Easements and rights-of-way.

Easements or rights-of-way of at least 15 feet in width shall be provided for all public sewers, water mains and other required underground utilities. The locations of such easements or rights-of-way shall be determined by the Board after consultation with the utility company or Borough department concerned.

Where a proposed subdivision is traversed by a natural stream or watercourse, there shall be provided a stormwater easement or a drainage right-of-way conforming substantially to the lines of such watercourses and such further width or construction, or both, as will provide adequate drainage. Improvements to all drainageways shall include cleaning, stabilization, provision of an access road for cleaning and maintenance at least along one side of same and other improvements as may be deemed necessary by the Borough Engineer.

Surface drainage easement for major and minor subdivisions and site plans may be required from the downstream property owner to the upstream property owner to permit continued passage of stormwater flow as required by existing conditions and the proposed development.

Pedestrian walks.

Pedestrian walks shall be provided along the frontage of all but industrial zones and in other locations deemed necessary by the Borough.

Pedestrian walks and sitting areas shall be surfaced so that they will be easily maintained and properly illuminated if in use after sunset. Walks along the frontage of property shall be in accordance with Borough standards.

Bikeways.

Bikeways may be required at the approving authority's discretion, depending on the development's location in relation to schools and recreation areas. Bicycle traffic shall be separated from motor vehicle and pedestrian traffic as much as possible.

Bikeways shall be designed and constructed in accordance with the standards and specifications as detailed in the Bicycle and Pedestrian Planning and Facilities Design Manual as sponsored by the New Jersey Department of Transportation.

Buffers.

Function and composition. A buffer shall provide a year-round visual screen for a particular property or area in order to minimize adverse impacts from a site on an adjacent property or from adjacent areas. A buffer shall consist of fencing, evergreens, berms, mounds or any combination thereof to achieve the stated objectives.

When required. Buffer areas shall be required along all lot lines and street lines which separate a nonresidential use from either an existing residential use or residential zoning district and/or where the approving authority has determined that there is a need to shield a site from adjacent properties and to minimize adverse impacts such as incompatible land uses, noise, glaring light, and traffic.

Size. Parking areas, garbage collection and utility areas, and loading areas shall be screened around their perimeter by a buffer a minimum of three feet wide.

Landscape requirements. All buffer areas shall be planted and maintained with either grass or ground cover, together with a living wall screen of live shrubs or scattered planting live trees, shrubs or other plant material meeting the following requirements:

The preservation of all natural wooded tracts shall be an integral part of all site plans and may be calculated as part of the required buffer area, provided that the growth of a sufficient density and the area has sufficient width to serve the purpose of a buffer. Where additional plantings are necessary to establish an appropriate tone for an effective buffer, said plantings may be required.

Planting materials used in screen plantings should be at least four feet in height when planted and be of such density as will obscure, throughout the full course of the year, the emitted glare of automobile headlights and other adverse impacts such as, but not limited to, noise, windblown debris, and other typical and frequent nuisance problems. The purpose of the screen plantings shall also be to create an aesthetically pleasing and attractive view to mask or obscure the use, function, or structure located upon the site.

The screen planting shall be so placed that at maturity it will not be closer than three feet to any street or property line.

Trees shall be at least eight feet in height and 2 1/2 inches in caliper when planted and be of a species common to the area, be balled and burlapped nursery stock and be free of insects and disease.

(e)

Any plant material which does not live shall be replaced within one year or one growing season.

(f)

Screen plantings and landscaping shall be broken at points of vehicular and pedestrian ingress and egress to assure a clean sight triangle at all street and driveway intersections.

Maintenance. All erosion and sediment control measures installed shall be maintained for one year after completion of the improvements or until such measures are permanently stabilized as determined by the Borough Engineer, whichever is longer. The Borough Engineer shall give the applicant, upon the applicant's request, certification of this determination.

Engineer report and public hearing. If no subdivision or site plan review is required, a separate report by the Borough Engineer shall be obtained. The Borough Engineer shall make a report on the application within 30 days of its receipt. The report shall comment upon all the requirements of this section, including but not limited to soil characteristics, slopes, quantities of soil involved, water table, drainage, road capacities, performance bonds and the utility of the site following completion of the operation. All applications shall require a public hearing as set forth in Chapter 50, Land Use Procedures.

Exemptions. The following activities are specifically exempt from the soil erosion and sediment control provisions:

Land disturbance associated with the construction of a single-family dwelling unit unless such unit is a part of a proposed subdivision, site plan, zoning variance or building permit application involving two or more such single-family dwelling units.

Land disturbances of 5,000 square feet or less of the surface area of land for the accommodation of construction for which the Standard Building Code of the State of New Jersey would require a building permit.

Agricultural use of land when operated in accordance with a farm conservation plan approved by the local soil conservation district or when it is determined by the local soil conservation district that such use will not cause excessive erosion and sedimentation.

Use of land for gardening primarily for home occupation.

(e)

Percolation tests and/or soil borings.

Topsoil protection. Prior to undertaking major grading operations, all topsoil shall be temporarily stockpiled. No topsoil shall be removed from the site. After completion of grading and construction in any area, the topsoil shall be spread and the soil stabilized by establishing vegetation in accordance with the requirements for soil erosion and sediment control. Where sufficient topsoil is not available on the site not to be paved or contain structures, the developer shall provide sufficient topsoil to accomplish same from off-site sources.

Steep slopes.

This subsection shall be applicable to new development or land disturbance on a steep slope within the Borough of South River.

Definitions. As used in this subsection, the following terms shall have the meanings indicated:

DISTURBANCE

The placement of impervious surface, the exposure or movement of soil or bedrock, or the clearing, cutting, or removing of vegetation.

IMPERVIOUS SURFACE

Any structure, surface, or improvement that reduces or prevents absorption of stormwater into land, and includes porous paving, paver blocks, gravel, crushed stone, decks, patios, elevated structures, and other similar structures, surfaces, or improvements.

REDEVELOPMENT

The construction of structures or improvements on areas which previously contained structures or other improvements.

STEEP SLOPES

Any slope equal to or greater than 20% as measured over any minimum run of 10 feet. Steep slopes are determined based on contour intervals of two feet or less.

Designation of areas. The percent of slope (rise in feet per horizontal distance) shall be established by measurement of distance perpendicular to the contour of the slope. The percent of slope shall be calculated for each two-foot contour interval. For example, any location on the site where there is a one-foot rise over a ten-foot horizontal run constitutes a ten-percent slope; a 1.5-foot rise over a ten-foot horizontal run constitutes a fifteen-percent slope; a two-foot rise over a ten-foot horizontal run constitutes a twenty-percent slope.

Steep slope limits.

For steep slopes, any disturbance shall be prohibited, except as provided below:

Redevelopment within the limits of existing impervious surfaces; and

New disturbance necessary to protect public health, safety or welfare, such as necessary linear development with no feasible alternative; to provide an environmental benefit, such as remediation of a contaminated site; to prevent extraordinary hardship on the property owner peculiar to the property; or to prevent extraordinary hardship, provided that the hardship was not created by the property owner, that would not permit a minimum economically viable use of the property based upon reasonable investment. For example, redevelopment, within the footprint of existing impervious cover, should be allowed to support efforts to revitalize development that has fallen into disrepair.

The applicant shall demonstrate through site plans depicting proposed development and topography that new disturbance is not located in areas with a twenty-percent or greater slope.

Enforcement; violations and penalties.

A prompt investigation shall be made by the appropriate personnel of the Borough of South River of any person or entity believed to be in violation hereof. If, upon inspection, a condition which is in violation of this subsection is discovered, a civil action may be brought in the Special Part of the Superior Court, or in the Superior Court, if the primary relief sought is injunctive or if penalties may exceed the jurisdictional limit of the Special Civil Part, by the filing and serving of appropriate process. Nothing in this Subsection I shall be construed to preclude the right of the Borough of South River, pursuant to N.J.S.A. 26:3A2-25, to initiate legal proceedings hereunder in Municipal Court. The violation of any part of this Subsection I shall constitute a separate and distinct offense independent of the violation of any other section or subsection or of any order issued pursuant to this Subsection I. Each day a violation continues shall be considered a separate offense.
