§ 93-10. Streets.

A. 

All roads or streets shall be at least 50 feet in width and shall have not less than 24 feet in width from curb to curb of actual paved area. The Planning Board may, in its discretion, require a wider paved area where safety conditions and hazards require such additional paving.

B. 

In general, within a block, road center lines deflecting at any point more than 10° shall be connected with a common tangent curve of radius not less than 300 feet for major roads and 200 feet for secondary roads. In all cases, both curb and property lines shall be parallel to or concentric with road center lines.

C. 

Grades of all roads shall be the reasonable minimum and, unless warranted by extenuating circumstances subject to the approval of the Planning Board, shall be not less than 0.5% nor more than 5% for major and secondary roads and not less than 0.5% or more than 10% for minor roads. A continuous gradient shall be used to facilitate surface drainage to proper natural or artificial outlets. All changes in road grades shall be connected by tangent vertical curves of not less than two-hundred-foot radius.

D. 

Major roads leading into arterial highways shall not be less than 60 feet wide and with a paved area not less than 30 feet wide. The Planning Board and the Planning Board consultant may, in the exercise of their discretion, require a wider paved area on such major roads wherever it shall be deemed necessary by said Planning Board and Planning Board consultant to provide such wider roads from a subdivision in order to provide suitable, safe roads for the accommodation of such traffic. Intersections of major roads with arterial highways shall be constructed with such curb radii and paved areas as may be required by the Planning Board consultant to properly safeguard traffic entering or leaving said arterial highways at major roads, and subject to the approval of state and county authorities having jurisdiction over such arterial highways. Property lines shall be established concentric thereto.

E. 

The Planning Board consultant, at his discretion, may require that a physical division be made between traffic lanes on major roads entering arterial highways for such distance back from the arterial highway as will, in his discretion, provide proper safeguards for the movement of traffic. The physical division between traffic lanes shall be a planted area, raised curb or other physical separation device as may be required by the Planning Board consultant. Insofar as practicable, major roads leading into arterial highways from subdivisions shall not be closer than 850 feet to each other, except in cases of unnecessary hardship or where, for reasons of diverse ownership of land, it is not possible. For the purpose of this chapter, any lot line abutting an arterial highway shall be deemed the rear lot line. No driveway from any abutting lot shall enter upon any arterial highway where access to any other street, road or highway is possible. There shall be no reserve strips controlling access to roads, unless the control of such strips is definitely placed in the Village under conditions approved by the Planning Board.

F. 

Insofar as practicable, all proposed roads shall be located in direct continuation of installed roads or in direct continuation of proposed roads shown on the Master Plan of the Village.

G. 

At the end of dead-end roads or culs-de-sac, provision shall be made for turning vehicles by way of a circle of not less than forty-five-foot radius to outer curb line or other adequate means of turning which may be approved by the Planning Board. Front lot lines abutting a cul-de-sac turning circle shall be not less than five feet outside of, and concentric with, the outer curbline as hereinabove defined.

H. 

All applications shall show the type of pavements, which shall conform to the minimum standards acceptable to the Planning Board consultant, as follows:

(1) 

Street paving. (Item numbers refer to New York State Department of Transportation Standard Specifications, January 3, 1978, and as amended.)

(a) 

One-and-one-half-inch-thick asphalt concrete top course, Type 7, Item 403.18.

(b) 

One-and-one-half-inch-thick asphalt concrete binder course, Type 2, Item 403.12.

(c) 

Five-inch subbase course, Type 2, Item 304.03.

(2) 

Curbs, gutters, drains and other drainage facilities shall conform to the specifications of the Village and the Nassau County Department of Public Works, which must also approve all drainage plans.

(3) 

All material and work shall conform to the specifications of the New York State Department of Transportation.

(4) 

The subgrade shall be firm, undisturbed ground or well-compacted fill acceptable to the Planning Board consultant. Where mud or slime exists, it shall be excavated to a minimum of four feet below the subbase and filled with clean fill, free of organic matter, and shall be acceptable to the Planning Board consultant. The subgrade shall be rolled until thoroughly compacted with a roller weighing not less than 10 tons. All work shall be done under the supervision of the Planning Board consultant or duly appointed inspector. All inspection fees shall be borne by the contractor or builder.
