Aberdeen Township City Zoning Code

§ 25-5.20

Streets and Curbs.

[Ord. No. 11-1985]
a. 
Streets.
1. 
All developments shall be served by paved public streets with an adequate crown. The arrangement of streets not shown on the Master Plan or Official Map, as adopted by the Township, shall be such as to provide for the appropriate extension of existing streets, should conform with the topography as far as practicable, and should be so oriented as to permit, within the limits of practicability and feasibility, the buildings constructed thereon to maximize solar gain.
2. 
When a new development adjoins land susceptible of being subdivided, suitable provisions shall be made for optimum access of the remaining and/or adjoining tract to existing or proposed streets.
3. 
Local streets shall be so planned and identified with appropriate signs so as to discourage through traffic.
4. 
In the event that a development adjoins or includes existing streets that do not conform to widths as shown on the adopted Master Plan and/or Official Map or the street width requirements of this Ordinance, additional land along either or both sides of said street, sufficient to conform to the right-of-way requirements, shall be dedicated for the location, installation, repair and maintenance of streets, drainage facilities, utilities and other facilities customarily located on street rights-of-way. The necessary deeds of ownership shall be furnished, and the dedication shall be expressed as follows: "Street right-of-way granted permitting the entrance upon these lands for the purposes provided for and expressed in the Land Development Ordinance of the Township." This statement shall in no way reduce the developer's responsibility to provide, install, repair or maintain the facilities in the area dedicated by ordinance and/or as shown on the plan and/or as provided for by any maintenance or performance guarantees. If the development is along one (1) side only, one-half (1/2) of the required extra width shall be dedicated. Additionally, that portion of the existing street or road adjoining or included within a site plan or major subdivision shall be improved, including excavation, grading, base courses and surfacing in accordance with the road improvement standards of this Ordinance.
5. 
In all developments, the minimum public street right-of-way shall be measured from lot line to lot line and shall be in accordance with the following schedule, but in no case shall a new street that is a continuation of an existing street be continued at a width less than the existing street although a greater width may be required in accordance with the following schedule.

(1)
Shall be grass stabilized topsoil, minimum four (4) inches thick.
(2)
Areas adjacent to curb available as parking or emergency area.
(3)
Except in specific instances where less pavement may be desirable.
Interior streets in APT/TM and PRD developments with no on-street parking and no dwellings fronting on the roadway: ROW Width = 40 feet, Cartway Width = 20 feet.
6. 
Street intersections shall be as nearly at right angles as is possible and in no case shall be less than sixty (60°) degrees and approaches to all intersections shall follow a straight line for at least one hundred (100) feet. No more than two (2) streets shall meet or intersect at any one (1) point and the centerlines of both intersecting streets shall pass through a common point. Measuring from this common point, two (2) intersections shall be spaced a sufficient distance to permit a minimum of two (2) lots or one hundred fifty (150) feet, whichever is greater, between the two (2) street rights-of-way. Any development abutting an existing street classified as an arterial or collector shall be permitted only one (1) new street connecting with the same side of the existing street except where the frontage is sufficient, more than one (1) street may intersect the arterial or collector street provided the streets shall not intersect with the same side of the existing street at intervals of less than eight hundred (800) feet for collectors and twelve hundred (1,200) feet for arterials. The block corners at intersections shall be rounded at the curbline with the street having the highest radius requirements as outlined below determining the minimum standard for all curblines: arterials - 40 feet; collectors - 35 feet; and local streets - 30 feet.
7. 
A tangent at least one hundred (100) feet long shall be introduced between reverse curves on arterial and collector streets. When connecting street lines deflect from each other at any one (1) point, they shall be connected by a curve with a radius conforming to standard engineering practice so that the minimum sight distance within the right-of-way shall be five hundred (500) feet for local streets, seven hundred fifty (750) feet for a collector street and one thousand (1,000) feet for an arterial street.
8. 
Culs-de-sac of a permanent nature (where provision for the future extension of the street to the boundary of the adjoining property is impractical or impossible) or of a temporary nature (where provision is made for the future extension of the street to the boundary line of adjoining property) shall serve no more than fifteen (15) lots and shall provide a turn-around at the end with a radius of fifty (50) feet on the curbline plus a utility and planting strip width of ten (10) feet around the entire cul-de-sac. The center point for the radius shall be on the centerline of the associated street or if off-set, off-set to a point where the radius becomes tangent to the right curbline of the associated street.
9. 
No street shall have a name which will duplicate or so nearly duplicate the name of an existing street that confusion results. The continuation of an existing street shall have the same name. Curvilinear streets shall change their names only at street intersections. The Board shall reserve the right to approve or name streets within a proposed development.
10. 
The pavement width of streets and the quality of surfacing and base materials shall adhere to the minimum standards set forth by the Township, County or State Engineers when said paving concerns roads under the jurisdiction and where such standards exist. Concerning streets under the jurisdiction of the Township, the following standards shall apply:
(a) 
The minimum requirements of any new street shall be constructed according to the specifications and procedures as set forth in the Standard Specifications.
(b) 
On all local roads, the base course shall be three (3) inches of Bituminous Stabilized Base, Stone Mix No. 1, placed on a compacted, unyielding subgrade consisting of a minimum of six (6) inches of graded quarry blend (Mix #5) which has been inspected and approved by the Township Engineer.
(c) 
On all Township collector and arterial streets, the base course shall consist of Bituminous Stabilized Base, Stone Mix No. 1, applied in two (2) lifts upon a compacted unyielding subgrade consisting of a minimum of six (6) inches of graded quarry blend (Mix #5) which has been inspected and approved by the Township Engineer. Township collector streets shall have four (4) inches of base course, while Township arterial streets shall have five (5) inches.
(d) 
The surface course for all classes of Township streets shall consist of one and one-half (1 1/2) inches of Bituminous Concrete, Type F.A.B.C.-1, Mix No. 5, applied according to state highway specifications.
(e) 
In all cases, a tack coat shall be applied between the surface course and the base course in accordance with the New Jersey State Highway Specifications.
11. 
The approval of any map of land delineating streets by the governing body of the Township shall in no way be construed as an acceptance of any street indicated thereon.
b. 
Curbs.
1. 
Belgian block or concrete curbing shall be installed along every street within a subdivision and at intersections with existing Township, County or State roads unless otherwise specified by the Township Engineer.
2. 
Concrete curbs for local roads shall be eight (8) inches wide at their base and not less than six (6) inches wide at their top. Their heights shall not be less than eighteen (18) inches and be constructed to show a vertical face above the roadway pavement of six (6) inches. The rear top corner of this curb shall have a radius of one-fourth (1/4) inch, and the front top corner shall have a radius of one and one-half (1 1/2) inches. Curbs at driveway openings shall be constructed to the full depth of eighteen (18) inches which depth shall extend a minimum of six (6) inches on either side of the depression.
3. 
If Belgian block, stones used for local roads shall not be less than ten (10) inches in height and shall be constructed to show a vertical face above the roadway pavement of six (6) inches. Stones used for Township collector and arterial roads shall not be less than twelve (12) inches in height and shall be constructed to show a vertical face above the roadway pavement of eight (8) inches.
c. 
Sight Triangles. Sight triangle easements shall be required at intersections, in addition to the specified right-of-way width, in which no grading, planting or structure shall be erected or maintained more than three (3) feet in height as measured from the mean elevation of the finished grade five (5) feet away from the centerline of the grading, planting or structure. The sight triangle is defined as that area outside the right-of-way which is bounded by the intersecting street lines and the straight line connecting "sight points," one (1) each located on the two (2) intersecting street centerlines the following distance away from the intersecting centerlines arterial streets @ three hundred (300) feet; collector streets @ two hundred (200) feet; and local streets @ ninety (90) feet. Where the intersecting streets are both arterial, both collectors or one (1) arterial and one (1) collector, the two (2) overlapping sight triangles shall be required to be formed by connecting the "sight points" noted above with a "sight point" ninety (90) feet on the intersecting street. Such easement dedication shall be expressed on the site plan or plat as follows: "Sight triangle deeded for the purposes provided for and expressed in the Land Development Ordinance."
