The subdivider shall observe the following requirements and principles of land subdivision in the design of each subdivision or portion thereof. All materials and construction practices for construction of streets, curbs, sidewalks, storm sewers, as well as the type and quantity of topsoil and other concrete work, shall be accomplished in accordance with the New Jersey State Highway Department Standard Specification for Road and Bridge Construction, 1983, and as amended, which shall hereafter be referred to as “Standard Specifications.”
The subdivision plat shall conform to design standards that will encourage good development patterns within the municipality. Where either or both an Official Map or Master Plan has or have been adopted, the subdivision shall conform to the proposals and conditions shown thereon. It is the intention of these regulations that proper performance of the work is the sole responsibility of the subdivider. The streets, drainage rights-of-way, school sites, public parks and playgrounds shown on an officially adopted Master Plan or Official Map shall be considered in approval of subdivision plats.
A. 
The arrangement of streets not shown on the Master Plan or Official Map shall be such as to provide for the appropriate extension of existing streets.
B. 
B.Minor streets shall be so designed as to discourage through traffic.
C. 
The Board may require that all lots with frontage on the arterial and collector streets of the Township, as listed in the Master Plan, shall have frontage on another minor street to serve as a point of access when this is deemed necessary. When frontage on a minor street is required, there shall be no driveway or other curb cut permitted along the frontage of the primary road.
D. 
All lots requiring reverse frontage shall have an additional 25 feet of depth above the requirements of Chapter 110, Zoning. At the discretion of the Planning Board, this 25 feet of depth will be planted by the developer in evergreen trees and shrubs so as to provide a visual screen at least six feet in height and covering 50% of the frontage of the property by the end of two growing seasons. The reverse frontage height of growth requirements can be met in part by grading dirt at a slope of one to three to a height of four feet within the twenty-five-foot reverse strip.
E. 
The right-of-way width shall be measured from lot line to lot line and shall not be less than the following:
(1) 
Arterial streets, 80 feet.
(2) 
Collector streets, 60 feet.
(3) 
Minor streets, 50 feet.
(4) 
The right-of-way width of internal roads and alleys in multifamily, commercial and industrial development shall be determined on an individual basis and shall never be less than 33 feet and shall in all cases be of sufficient width and design to safely accommodate the maximum traffic, parking and loading needs and maximum access for fire-fighting equipment.
F. 
No subdivision showing reverse strips controlling access to streets shall be approved except where the control and disposal of land comprising such strips has been placed in the governing body under conditions approved by the Board.
G. 
Subdivisions that adjoin or include existing streets that do not conform to width as shown on the Master Plan or Official Map or the street width requirements of this chapter shall dedicate additional width along either one or both sides of said road. If the subdivision is along one side only, 1/2 of the required extra width shall be dedicated. If a realignment of an existing road is proposed, the developer shall provide not less than 1/2 of the future width of the side or sides owned by him or her and 1/2 of the future width from the new center line through any parcels not owned by him. It shall be the developer's obligation to obtain the required right-of-way from the owner/owners of the lands not owned by the developer which are affected by the proposed realignment.
H. 
Grades of arterial and collector streets shall not exceed 4%. Grades on other streets shall not exceed 10%. No street shall have a grade of less than 1/2 of 1%. Special details may be required where grades exceed 2 1/2%.

(2) 
Subgrade. The subgrade shall be in a proper, finished condition conforming to the proper line and grade and free of any soft spots or other deficiencies. The subgrade shall be tested by running a roller, of a weight at least equal to that to be used in the paving operation, over the entire subgrade. If the deformation of the subgrade is excessive in the opinion of the Engineer, the subgrade must be stabilized in a manner satisfactory to the Engineer. Adequate underdrains shall be constructed where the seasonal high groundwater level is within two feet of the surface of the subgrade.
(3) 
Subbase course. If the subgrade has a CBR value of 10 or greater as determined by the American Society for Testing and Materials method for Bearing Ratio of Laboratory-Compacted Soils (ASTM Designation D 1883), no subbase course is required. Subgrade soils of Type A-1, A-2-4 and A-2-5 of the American Association of State Highway Officials Classification System for Soils (ASSHO Designation M 145) will not normally require a subbase course. Subgrade soils of other types will normally require a subbase course of soil aggregate Type 2, Class A or B, four inches minimum thickness to provide the required CBR value.

Base course. All minor streets shall have a bituminous stabilized base course five inches thick. All collector and arterial streets shall have a macadam base course six inches thick.
(5) 
Surface course. The surface course shall be bituminous concrete surface course, hot mixed, Type 1-4, three inches thick. A tack coat of asphaltic oil shall be applied to the base course prior to the construction of the surface course. The surface course shall not be constructed until a minimum of one year after the construction of the base course. Immediately after construction of the base course the area around manholes, valve boxes, inlets and other similar facilities shall be ramped with bituminous concrete for safety until the surface course is constructed.
(6) 
Test cores. Prior to the construction of the top course but at least six months after the construction of the base course, one core sample for each 200 square yards of paving shall be taken at points designated by the Engineer. The contractor shall cut the cores with a coring machine, jackhammer or other means approved by the Engineer. One core from every 10,000 square yards, or part thereof in the event that there is less than 10,000 square yards of base course, but not less than two core samples shall be analyzed by an approved testing laboratory and the results submitted to the Engineer. Any deficiencies shall be corrected prior to the construction of the top course.
K. 
Street intersections shall be as nearly at right angles as is possible, and in no case shall be less than 60°. The block corners at intersections shall be rounded at the curbline with a curve having a radius of not less than 20 feet. Any intersection of other than 90° may be treated as an exception to above and special requirements may be imposed.
L. 
Street jogs with center-line offsets of less than 125 feet shall be permitted, except where compliance with this requirement is impossible or not feasible.
M. 
Between reverse curves, a tangent shall be introduced of at least 100 feet on arterial and collector streets and 50 feet on minor streets.

If a dead-end street is of a temporary nature, a similar turnaround shall be provided and provisions made for future extension of the street and reversion of the excess right-of-way to the adjoining properties. The length of a temporary cul-de-sac shall be determined by the Board.
Q. 
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.
R. 
Such design features as multilegged intersections with more than four legs, acute angle V-type intersections and jog intersections are prohibited.
S. 
Continuous minor streets extending from one arterial or collector street to another arterial or collector street should be avoided.
T. 
Four-legged intersections shall not be proposed, except where unavoidable. T-type intersections shall be encouraged.
U. 
Curbs shall be six-by-eight-by-eighteen-inch concrete curbs, all in accordance with the Standard Specifications, Class B concrete. Curbs shall be rounded at intersections with a minimum radius of 25 feet at minor streets, 35 feet at collector streets and 45 feet at arterial streets. Where two or more streets of different classifications intersect, the minimum radius provided shall be that specified for the street of the higher classification. Handicapped ramps shall be provided at all intersections and in the curbline of a through street opposite the corners of any intersecting street.
V. 
Sidewalks shall be of the width specified in Subsection I above and shall be a minimum of four inches thick, except at driveway openings where they shall be a minimum of six inches thick and reinforced with six-inch-by-six-inch 10-10 wire mesh. The apron shall be Class A concrete.
A. 
Block length and width or acreage within bounding roads shall be such as to accommodate the size of lot required in Chapter 110, Zoning, and to provide for convenient access, circulation control and safety of street traffic. Block lengths shall not normally exceed 1,200 feet.
B. 
In blocks over 1,000 feet long, pedestrian crosswalks may be required in locations deemed necessary by the Planning Board. Such right-of-way shall be at least 15 feet wide and be straight from street to street and contain a four-foot-wide sidewalk, but no planting of shrubs or trees or building of fences or other obstructions shall be permitted on such fifteen-foot walkway.
C. 
For commercial or industrial use, block size shall be sufficient to meet all area and yard requirements for such use.
D. 
At all intersecting streets, the corners of blocks shall be rounded to be concentric with the curb.
A. 
Lot dimensions and area shall not be less than the requirements of Chapter 110, Zoning, and be appropriate to the topography and natural character of the land being subdivided, and be appropriate to the type of development and use contemplated.
B. 
Insofar as is practical, side lot lines shall be at right angles to straight streets and radial to curved streets.
C. 
Each lot must front upon an approved street at least 50 feet in width, except lots fronting on streets described in § 100-31E(4) of this article.
D. 
Where extra width has been dedicated for widening of existing streets, lots shall begin at such extra width line, and all setbacks shall be measured from such line.
E. 
Where there is a question as to the suitability of a lot or lots for their intended use due to factors such as rock formations, flood conditions or similar circumstances, the Planning Board may, after adequate investigation, withhold approval of such lots.
F. 
Excessive conformity and excessive nonconformity in building setback line shall be avoided.
G. 
The Planning Board shall not approve any subdivision which permits more than one principal residential use on any one lot except in cases where multiple-family structures are permitted by ordinance.
A. 
In large-scale development, easements along rear property lines or elsewhere for utility installation may be required. Such easements shall be at least 20 feet wide and located in consultation with the companies or municipal departments concerned, but no planting of shrubs or trees or building of fences or other obstructions shall be permitted on such twenty-foot easement.
B. 
Natural features such as trees, brooks, hilltops and views shall be preserved whenever possible in designing any subdivision containing such features. They shall be modified only insofar as necessary to provide protective drainage and water runoff slopes away from all sides of all buildings. Due consideration shall be given to the laying out of adequate parks and playgrounds in residential areas for dedication to the Township or reservation for common use of the public by deed, covenants or agreements which are approved by the Planning Board. Areas for parks and playgrounds shall be of reasonable size for neighborhood recreational use and shall be conveniently located.
C. 
Sight triangle easements. Sight triangle easements shall be provided and shown with dimensions on the preliminary and final map at all street intersections. Such easements shall be provided between the right-of-way line of the street and straight lines connecting points on the center line of the intersecting streets the following distances from the intersection of the center lines of the intersecting streets:
(1) 
Arterial with arterial, arterial with collector and arterial with minor streets: 300 feet on the street of higher classification or the through street and 90 feet on the other.
(2) 
Collector with collector and collector with minor streets: 200 feet on the street of higher classification or the through street and 90 feet on the other.
(3) 
Minor streets: 90 feet.
A. 
Active recreational facilities, together with associated open space, shall be provided for each residential development where the development exceeds four dwelling units. Recreation facilities shall be provided in accordance with the table and provisions set forth below. The table acknowledges the fact that lot sizes are adequate to provide on site facilities for the recreation of toddlers and small children, but the purpose of this provision is to protect the need of older children and adults for recreational activities that necessitate common open space. For any cluster housing developments that may be permitted, the active recreation facilities, plus parking areas, shall be located in that open space area derived as a result of clustering the dwelling units. In other single-family detached housing developments, a minimum of 10% of the land will be dedicated for both active and passive open space, unless less land is needed in the Joint Land Use Board's opinion based on the lot layout and arrangement and/or size and number of the lots. An area sufficient in size to accommodate the active recreation facility, plus the associated required off-street parking, shall be located in the common open space area, in accordance with the table set forth below:
Type of Recreation Facility
Minimum Area
Tennis court
10,000 square feet, plus parking area
Basketball court
8,000 square feet
Multipurpose field area
2 acres, plus parking area
B. 
No active recreational area shall be less than 8,000 square feet in area nor less than 60 feet in width. All recreational areas shall be located convenient to dwelling units.

C. 
Parking spaces for off-street parking will be required for each tennis court and each multipurpose field in the same area and on the same site as that active recreational facility which it serves. Four parking spaces will be required for each tennis court and 20 spaces will be required for each multipurpose field. Paving specification for the off-street parking facility shall meet the parking standard for paving in the commercial area.
D. 
A buffer area 30 feet in width shall surround the nonstreet side to each active recreational area and the parking area required to support the same. Said buffer area shall be designed, developed and maintained in accordance with the provisions for buffers as set forth elsewhere in the Delanco Township Zoning Ordinance.[1] Landscaping within the active recreation area itself may be used as a basis for the request for a reduction of the screening within the buffer area, and the type of active recreation facility which is bounded by a portion of the perimeter property line may also be used as a basis for a request for a reduction of screening requirements (i.e., outfield of multipurpose field, as opposed to infield or foul lines). The adequacy of the buffering, landscaping and screening must be reviewed by the Township Engineer and/or the Township Planning Consultant as part of the landscape plan presented to the reviewing authority.
[1]
Editor;s Note: See Ch. 110, Zoning.
E. 
Recreational facilities for a type different than those mentioned above may be proposed for substitution by the developer or requested by the Board and submitted for approval of the Board.
F. 
Recreational facilities shall be substituted on a dollar-for-dollar cost basis, with cost figures submitted by the developer, and shall be of a type to serve the same general age group for whose use the original recreational facility was intended.

L. 
Recreation facilities are required based on the number of dwelling units for the project as is set forth in this Code. Where two or more developments are proposed for construction or are in the process of construction, which developments are either adjacent to one another or are in close proximity to one another, the number of dwelling units in the two developments shall be added together to determine the type of recreation facilities needed for the area, and the responsibility for providing and constructing the recreation facilities so determined shall be allocated proportionately between or among the developments.
M. 
In lieu of construction of the required recreation facilities for the development and the dedication of open space, the developer may propose a contribution to the Township's recreation fund for all or part of said facilities. The contribution in lieu of construction and dedication shall be $1,250 per dwelling unit, which shall be increased annually by 5%. Payment in lieu of construction shall be made as a condition of approval by the Joint Land Use Board and shall be paid upon the issuance of the certificate of occupancy for each dwelling unit. The Joint Land Use Board and the Township may elect to refuse a contribution and to require the construction if it is felt that the location of the development is such that construction of all or part of the required recreational amenities is necessary at this location because the site is too far from present Township facilities. All contributions to the recreation fund shall be used only for that purpose and shall be administered in accordance with the requirements, rules and regulations governing the recreation fund. The recreation fund shall be administered and controlled by the Township Committee.

At least two street name signs shall be placed at each four-way street intersection, and one at each “T” intersection. Signs shall be installed under light standards, and free of visual obstructions. They shall be of a style and design the same as existing signs in the Township.
C. 
Site information signs in planned developments shall follow a design theme that is related and complementary to other elements of the overall site design.
A. 
The lot shall be subgraded to an elevation not less than four inches lower than the elevation indicated on the preliminary plat.
B. 
The topsoil shall then be placed in accordance with 7.5 of the Standard Specifications. The topsoil shall meet the following requirements:
(1) 
Topsoil shall contain no stones, lumps, roots or similar objects larger than two inches in any dimension, and shall have pH value of not less than 5.8 nor more than 6.5. When the pH value of the topsoil is less than 5.8, it shall be increased by applying ground limestone at a rate necessary to attain a pH value of 6.5.
(2) 
Topsoil shall have a minimum organic content of not less than 2 3/4% by weight. When the organic content of the topsoil is less than 2 3/4%, it shall be increased by adding peat at a rate necessary to attain this minimum organic content. The organic content of soils shall be determined by the laboratory using the chromic acid duration method as described in the United States Department of Agriculture's Circular 757. The gradation of the topsoil shall be determined by the laboratory using the Bouyouces Hydrometry Analysis conforming to the requirements of current AASHO Designation T 88, within the following ranges:
(a) 
Sand (2,000 millimeters to 0.050 millimeters) 40% to 80%.
(b) 
Silt (0.050 millimeters to 0.005 millimeters), 10% to 30%.
(c) 
Clay (0.005 millimeters and smaller), 10% to 30%, except that when 1/2 of the sand content is larger than 0.500 millimeters, the maximum sand content shall be 75% and the minimum clay content shall be 15%.
(3) 
Topsoil shall be placed in such a manner as to have a minimum depth of four inches after it has been thoroughly compacted by repeated watering. The Construction Code Official shall inspect the depth of the topsoil and certify as to its conformity.
A. 
Lighting shall be provided in accordance with a plan designed by the utility company, or using as a guideline the standards set forth by the IES Lighting Handbook shown in Exhibit I.[1] Streetlighting shall comply with § 91-89C et seq., entitled "Lighting; purpose and intent."

Editor's Note: Exhibit I is on file in the Township offices.
B. 
Lighting for safety shall be provided at intersections, along walkways, at entryways, between buildings and in parking areas.
C. 
Spacing of standards shall be equal to approximately four times the height of the standard.
D. 
The maximum height of standards shall not exceed the maximum building height permitted, or 25 feet, whichever is less.
E. 
The height and shielding of lighting standards shall provide proper lighting without hazard to drivers or nuisance to residents, and the design of lighting standards shall be of a type appropriate to the development and the Township.
F. 
Spotlights, if used, shall be placed on standards pointing toward the building rather than on the building and directed outwards, which creates dark shadows adjacent to the buildings.
G. 
All electric, telephone, television and other communication lines, both main and service connections, servicing new developments shall be provided by underground wiring within easements or dedicated public rights-of-way, installed in accordance with the prevailing standards and practices of the utility or other companies providing such services.
H. 
Lots that abut existing easements or public rights-of-way where overhead electric or telephone distribution supply lines and service connections have previously been installed may be supplied with electric and telephone service from those overhead lines, but the service connections from the utilities' overhead lines shall be installed underground. In the case of existing overhead utilities, should a road widening, or an extension of service, or other such condition occur as a result of the subdivision and necessitate the replacement or relocation of such utilities, such replacement of relocation shall be underground.
I. 
Where overhead lines are permitted as the exception, the placement and alignment of poles shall be designed to lessen the visual impact of overhead lines. Alignments and pole locations shall be carefully routed to avoid locations along horizons; clearing swaths through treed areas shall be avoided by selective cutting and a staggered alignment; trees shall be planted in open areas and at key locations to minimize the view of the poles and the alignments; and alignments shall follow rear lot lines and other alignments.
J. 
Year-round screening of any utility apparatus appearing above the surface of the ground, other than utility poles, shall be required.

A. 
Location. Shade trees shall be planted within the public right of way between the curb, or the edge of road if no curb, and the edge of the existing sidewalk or sidewalk easement, on both sides of all streets according to a plan that complies with Chapter 238 of this Code and is approved by the Delanco Shade Tree Commission.
B. 
Tree type. Tree types may vary depending on the overall effect desired, but selection shall be approved by the Delanco Shade Tree Commission.
C. 
Planting specifications. All trees shall have a caliper of two 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.
