The final plat of the subdivision shall conform to the following principles and standards of the design:
(A) General. The subdivision plan shall conform to the principles and standards relevant to use which are generally exhibited in the Comprehensive Master Plan as approved.
(B) Streets.
(1) The street or alley layout shall provide access to all lots and parcels of land within the subdivision, and where streets cross other streets, jogs shall not be created.
(2) Proposed streets shall be adjusted to the contour of land so as to produce usable lots and streets of reasonable gradient.
(3) Certain proposed streets, where appropriate, shall be extended to the boundary lines of the tract to be subdivided so as to provide for normal circulation of traffic within the vicinity.
(4) Wherever there exists a dedicated or platted portion of a street, or alley adjacent to the proposed subdivision, the remainder of the street or alley to the prescribed width should be platted within the proposed subdivision.
(5) The minimum right-of-way of streets shall be 50 feet. All cul-de-sacs shall terminate in a circular right-of-way with a minimum diameter of 100 feet and not nearer than 50 feet to the subdivision or block boundary, or as same shall be dictated by the relevant town regulatory authorities (Planning and Zoning Board, Board of Zoning Appeals, and Town Council).
(6) Alleys shall be discouraged in residential districts but should be included in commercial and industrial areas where needed for loading and unloading or access purposes and shall have a minimum width of 30 feet.
(7) The centerlines of streets should intersect as nearly at right angles as possible.
(8) At intersections of streets and alleys, property line corners shall be rounded by arcs of at least 15 feet radii or by cords of such arcs.
(9) If the smaller angle of intersection of two streets is less than 60 degrees, the radius of the arc at the intersection of property lines shall be increased as deemed advisable by the Board.
(10) Intersections of more than two streets at one point shall be avoided.
(11) Where special types of streets are involved, the Commission may apply special standards to be followed in their design.
(12) Whenever the proposed subdivision contains or is adjacent to a railroad right-of-way, provision shall be made for a parallel street at a distance acceptable for the appropriate use of the land between the street or railroad and such streets.
(C) Blocks.
(1) Blocks shall not exceed 1,500 feet in length.
(2) Blocks shall be sufficient width to permit two tiers of lots of appropriate depth except where an interior street parallels a limited access highway or arterial streets.
(D) Lots.
(1) All lots shall abut on a street, cul-de-sac or place.
(2) Sidelines of lots shall be at approximate right angles to straight streets and on radial lines on curved streets. Some variations from this rule are permissible at the discretion of the Commission but pointed or very irregular lots should be avoided.
(3) Double frontage lots should not be platted, except that where desired highways or streets, lots may face on an interior street and back on such thoroughfares. In that event a planting strip at least 20 feet in width for a screen shall be provided along the back of the lot.
(4) Widths and areas of residential lots shall be not less than provided in the zoning ordinance for single-family dwellings (R) for the district in which the subdivision is located.
(E) Easements. Where alleys are not provided, easements for utilities shall be provided. Such easements shall have minimum widths of 20 feet, and where located along lot lines, one-half the width shall be taken from each lot. When such easements are to be located along the boundary of the plat, the full width of the easement may be required within the plat at the discretion of the town. Before preparing the final plat, the plan of easements shall be discussed with the local public utilities to assure their proper placing for the installation of such services.
(F) Building setback lines. Such lines shall be as provided in the zoning ordinance or as the Commission may determine.
(G) Public open spaces. Where proposed sites for parks, schools, playgrounds, or other public uses are located within the subdivision area, or where such sites appear to be desirable, the Board may request their reservation for a period of five years following the date of this final approval of the plat. In the event a governmental agency concerned passes a resolution expressing its intent to acquire the land so reserved, the reservation period shall be extended for an additional one year.
(H) Drainage right-of-way.
(1) Whenever a subdivision is traversed by a watercourse, drainage way, channel or stream, there shall be provided a drainage right-of-way, notwithstanding the provisions or the relevant county authorities, which shall be for the purpose of widening, improving or protecting the stream. The width of the drainage right-of-way shall be adequate for any necessary channel relocations and straightening. Parallel streets may be required in connection therewith.
(2) Flood prone areas. All subdivisions development plans shall indicate flooding and floodway fringe limits and shall have the elevation of the base flood shown thereon.
