The Town of Deerpark Planning Board shall determine and designate into which of the two following classifications each proposed subdivision street falls on the basis of one or more of the criteria hereinafter set forth. After submission of plans for review to the Town of Deerpark Superintendent of Highways and the Engineer for the Town of Deerpark.
[Amended 7-21-1986]
(1) 
Suburban type street.
(2) 
Rural type street.
B. 
Final plans shall be drawn to show, and the developer shall construct each street in accordance with the particular specifications for its designated classification as hereinafter set forth as well as in accordance with the specifications common to all classifications.
A. 
Suburban type streets.
(1) 
The proposed street will serve residential subdivisions with lot size less than one acre and with more than eight lots to be developed in the subdivision at option of the Town of Deerpark Planning Board.
(2) 
The proposed street may be dead-end street with 140 feet diameter cul-de-sac, a loop (through street) or a street connecting to existing Town, county, or state highway.
(3) 
The proposed street may be used for commercial or industrial purposes.
B. 
Rural type streets.
(1) 
The proposed street will serve residential subdivisions with lot sizes of one acre or more, or with smaller lot sizes, if not more than eight lots are to be developed in the subdivision, and where rezoning to smaller lot size is not designated in the Zoning Ordinance, or contemplated in the Comprehensive Plan, at the option of the Town of Deerpark Planning Board.[1]

Editor's Note: See Ch. 230, Zoning, and Ch. A235, Comprehensive Plan.
(2) 
The above design criteria is the basis for design with the Town of Deerpark Planning Board having final determination, and it may override or suggest certain changes within the design criteria of suburban and rural type streets.
Private roads within the Town of Deerpark are not acceptable, however, under certain circumstances, may be allowed only by the Town of Deerpark Planning Board approval.
In his written certification, as required, the developer's professional engineer shall state clearly that he or his authorized representative has inspected all phases of the street construction and that all work has been completed in accordance with the approved plans and specifications.
A. 
A plan of the proposed street shall be prepared by a qualified professional engineer licensed by the State of New York. The plan shall clearly define the limits of the proposed right-of-way by metes and bounds and shall include the location, widths, profiles and grades of the proposed roadways, storm drainage, including culverts and other drainage structures and the locations of all easements and utilities. The plans shall also indicate owner of property and name of developer if other than owner. One copy of each of the plans shall be submitted to the Town of Deerpark Superintendent of Highways and Town of Deerpark Town Engineer at the time of application to make such road a Town road, and to the Orange County Superintendent of Highways when said proposed street drains toward, intersects or may otherwise affect a county highway. It will then be submitted to the Town of Deerpark Planning Board for review and approval under the applicable subdivision regulations of the Town of Deerpark. Such roadway must not be subject to any right-of-way or easement of others which will in any way interfere with its use as road at all times. Such roadways must be granted to the Town of Deerpark by a full covenant and warrantee deed containing the correct metes and bounds description as shown on the approved map, which deed must be in such form as may be required to entitle the same to be recorded in the Office of the County Clerk of Orange County. A policy of title insurance or other assurance of title satisfactory to the Town Attorney shall be provided to the Town of Deerpark when the road offered is accepted. All expenses incidental to the dedication and acceptance of any road shall be borne by the applicant.
[Amended 7-21-1986]
B. 
Permanent and temporary easements must be furnished in said deed granting to the Town of Deerpark the right to maintain all outlets of culverts and drainage structures for surface water or natural stream drainage which will run from such roadway over private property to a point where a natural watercourse exists and to which such outlet and easement will carry such water. A minimum of 20 feet width of easement shall be required for the maintenance of said easements.
C. 
The proposed roadway must be constructed to conform to the minimum requirements and standards set forth below. The minimum width to be cleared shall include all trees, rock formations, buildings, walls and any such things that would endanger those using such roadways. The removal of such obstructions shall be borne by the person or firm proposing such road.
A. 
Plans submitted shall not be altered or amended after having been approved by the Town of Deerpark Superintendent of Highways, unless amended plans are resubmitted and approved. However, the developer, at his own expense, shall provide additional storm drainage facilities or utilities as may be ordered by the Town of Deerpark Superintendent of Highways.
B. 
If during the course of construction, in the opinion of the Town of Deerpark Superintendent of Highways, the Town of Deerpark Engineer, such additional structures or facilities are necessary to prevent any need for future installation of utilities or culverts within the pavement area, to assure the durability of pavement, further maintenance of right-of-way, or welfare and safety of the public, unless such variance conflicts with the provisions of a Town or county official drainage map, in which event, the official map shall prevail. If construction of said road has not been started within one year from date of final approval by the Town of Deerpark, plans shall be resubmitted and approved as above.
A. 
Performance bonds. Prior to the start of construction of any street, the developer shall deposit with the Town of Deerpark Town Clerk a performance bond of acceptable surety or shall deposit with the Town of Deerpark Chief Fiscal Officer acceptable negotiable government bonds, cash or certified check drawn upon a national or state bank, payable at sight to the Town of Deerpark Town Board guaranteeing:
