(A) General Street Plan. All subdivision streets shall conform as to width and location to the general street or thoroughfare plan for the town.
(B) Right-of-Way. The minimum right-of-way for streets shall be 60 feet. Additional right-of-way may be required for other than residential streets in accordance with the general street plan as adopted by the Board of Aldermen. Streets or lanes having length of 400 feet or less and being open or connected at one end only shall be not less than 50 feet. A partial width street, so designated, may be dedicated when adjoining undeveloped property; provided, that the width of the dedication, when permitted by the Planning Board and approved by the Board of Aldermen, shall be such as to permit the installation of the public facilities as may be necessary to serve the lots abutting thereon. The owner of a subdivision of land abutting an existing partial width street shall be required to dedicate the remainder of the full required width of the street.
(C) Alleys. The minimum width of any alley shall be 20 feet, except in commercial districts where the minimum width shall be not less than 22 feet. Alleys shall be required in all blocks along the rear line of business property.
(D) Easements. Where alleys are not provided, easements of not less than five feet in width shall be provided on each side of all rear lot lines where necessary or in other locations as may be directed by the Planning Board, subject to final approval by the Board of Aldermen, for poles, wires, conduits, storm or sanitary sewers, telephone, and water lines. Easements of greater width may be required along the lines of or across lots where necessary for storm drainage channels, surface overflow or for the extension of main sewers or similar utilities.
(E) Culs-de-Sac. Culs-de-sac and dead-end streets shall terminate in a circular right-of-way having a minimum radius of 40 feet. This provision may be modified by the Planning Board, subject to final approval by the Board of Aldermen. The culs-de-sac shall not exceed 400 feet in length.
(F) Intersecting Streets. Intersecting streets shall be laid out at intervals that block lengths are not more than 800 feet, except where the principal street serves lots fronting upon water areas and access by intersecting street is not required; or where the principal street serves a narrow island, strip of land, peninsula or is a cul-de-sac; or where, in the opinion of the Planning Board, subject to final approval by the Board of Aldermen, existing conditions justify a modification of this requirement.
(G) Block Widths. Blocks shall be wide enough to allow two tiers of lots of minimum depth, plus alleys if needed and easements, except when prevented by topographical conditions or the size of the property in which case the Planning Board may approve a single tier of lots of minimum depth.
(H) Public Access. Public access shall be provided in accordance with the recommendations of the town's land use plan and access plan, and/or the present amount of public access and public parking as exists within the town now. If any recommendations are found to conflict, the system requiring the greatest quantity and quality of public access, including parking, shall govern.
