Subd. 1. Length. The length, width, and acreage of blocks shall be sufficient to accommodate the size of lots required for the area by the zoning ordinance and to provide for convenient access, circulation, control, and safety of street design. The maximum length of blocks shall be 1,500 feet and the minimum length 400 feet. Blocks over 900 feet long may require pedestrian ways at least 30 feet wide at their approximate center. The use of additional pedestrian ways to schools, parks, and other destinations may be required.
Subd. 2. Arrangement. A block shall be so designed as to provide two tiers of lots unless it adjoins a major collector, arterial street, railroad, thoroughfare, watercourse, or park, or where topographic or other conditions render the block arrangement unreasonable.
