(A) The length, width and shapes of blocks shall be determined with due regard to:
(1) Provision of adequate building sites suitable to the special needs of the type of use contemplated;
(2) Zoning requirements as to lot sizes and dimensions; and
(3) Needs for convenient access, circulation control and safety of street traffic.
(B) In general, intersecting streets determining the block length and width shall be provided at intervals so as to serve cross traffic adequately and to meet existing streets or in accordance with customary subdivision practices.
(1) Where no existing subdivision controls, the block lengths shall generally not exceed 800 feet along local streets, 1,000 feet along collector streets, or 1,200 feet along arterial streets. Where no existing subdivision controls, the blocks shall generally not be less than 400 feet along local or collector streets, or 500 feet along arterial streets.
(2) However, in cases where physical barriers or property ownership creates conditions where it is appropriate that these standards be varied, the length may be increased or decreased to meet the existing conditions having due regard for connecting streets, circulation of traffic and public safety. Where opposite sides of a block are along different classifications of streets, the length shall generally conform to the maximum and minimum limits applicable to the higher classification.
(C) Where blocks in the vicinity of a school, park or shopping center are 1,000 feet or longer, the Commission may require a six-foot public pedestrian access easement near the middle of the block or at a street that terminates between streets at the ends of the block.
(D) Where no existing subdivision controls, the block depth shall be platted to give lots with depth to width ratios of generally not more than two and one-half to one and in no case more than four to one, and the design shall be such that the block depth generally shall not exceed 350 feet. When possible, the block width and length shall be such to allow tiers of lots back to back.
(E) Blocks shall be labeled sequentially, from "One" or from "A" in each subdivision or section thereof.
