(A) Determination of length, width and shape. The length, width and shape 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) Need for convenient access, circulation, control and safety of street traffic.
(B) Specifications for length. In general, intersecting streets, which determine the block lengths and widths, shall be provided at such intervals as to best serve cross traffic adequately and to meet existing streets, or to comply with customary subdivision practices. Where there is no existing subdivision to control, the block lengths shall not exceed 1,600 feet, and shall generally be 1,000 to 1,200 feet in length; nor shall any block be less than 500 feet in length; however, in 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.
(C) Specifications for width. Where no existing subdivision controls, the block depth and/or width shall be platted to give lots with a depth-to-width ratio of generally not more than two and one-half to one, and in no case more than four to one, and the platting shall be such that the block width or depth generally shall not exceed 350 feet nor be less than 215 feet. When possible, the block width and depth shall be such as to allow two tiers of lots back-to-back.
(D) Walkways. Where blocks in the vicinity of a school, park or shopping center are platted, 1,000 feet or longer, the Council may require a walkway near the middle of the block, or at a street that terminates between the streets at the end of the block. The walkway shall not be less than four feet nor more than eight feet in width, and shall have a four-foot concrete walk through the block from sidewalk to sidewalk, or to the rear of the property line, if no street exists.
(E) Sidewalks. Where pedestrian walks are required by the city, they shall not be less than four feet wide and shall be provided around the perimeter of all blocks.
