(A) Measurement criteria.
Block lengths are to be determined by the measurement along the face of a block (being the adjacent street right-of-way line) from one street intersection to another street intersection where the streets provide cross-traffic circulation (not cul-de-sac street). In those instances where a loop street configuration is involved the interior block formed by the loop streets is measured through the center of the block and between adjacent street right-of-way lines. Variations in the block lengths herein specified may be considered by the city upon receipt of a request from the subdivider for a variance and in those situations where a block may be adjacent to a major topographical feature, such as a river, canal, bayou, gully, ravine, a major drainage ditch, lake, pit, or mine excavation; a major right-of-way or easement for high voltage electrical transmission lines, underground pipelines, railroad rights-of-way, and facilities; designated freeways; a public park or other publicly owned and operated facilities such as dams, reservoirs, schools, airports, or golf courses and; privately owned golf courses and lakes when the golf courses and lakes are an integral part of the layout and subdivision design of the overall tract being developed. In no instance, however, will the Council grant a variance indicating that a block adjacent to the conditions and features mentioned above to be more than 2,640 feet (one-half mile) in length measured along the block face.
(B) Major thoroughfares.
The maximum length for blocks adjacent to designated major thoroughfares must not be more than 1,800 feet.
(C) Local streets.
The maximum length for blocks adjacent to local streets must not be more than 1,000 feet, except under the following circumstances.
(1) Loop streets may have an internal block length of not more than 800 feet.
(2) Cul-de-sacs may have a block length of not more than 800 feet, measured from the intersection with the right-of-way of a cross street along the center line of the cul-de-sac street to the center of the circular turnaround at the end of the cul-de-sac.
(3) Stub streets or dead ends may have a block length of no more than 800 feet unless terminated with a circular turnaround suitably modified to accommodate future extension of street into adjacent property.
(D) Private streets.
See § 154.28(E) regarding the length of cul-de-sac or dead-end private streets.
