(A) Length. Blocks in residential subdivisions shall be a minimum of 400 feet long and normally not exceed 1,000 feet in length except where topography or other conditions justify a departure from this maximum. In blocks longer than 800 feet, the County Board may require that pedestrian ways be located near the center of the block.
(B) Width. With the exception of lots abutting a major street to which access is not permitted, residential lots shall be of sufficient size to permit two tiers of lots of appropriate depth. Commercial or industrial lots shall be of sufficient width to accommodate structures and required off-street parking, access and loading facilities.
