The following regulations shall govern the design and layout of blocks:
(a) The arrangements of blocks shall conform to the street design criteria set forth in these regulations.
(b) Blocks shall be arranged to accommodate lots and building sites of the size and character required by these regulations and the City's Zoning Code to provide for adequate community facilities, and with regard of the limitations and opportunities of topography.
(c) Irregularly shaped blocks, blocks intended for cul-de-sacs and loop streets, and blocks containing interior parks and playgrounds may be approved by the Planning Commission if properly designed and located.
(d) No block shall be larger than (1400) feet, or (12) times the minimum lot width required in the zoning district, and no less than (800) feet. Cross streets shall be provided between blocks.
(e) Where blocks are more than (900) feet in length, a walkway easement not less than (10), feet in width at or near the halfway point of the block may be required between streets.
(f) Blocks in the traditional gridiron pattern should consist of two tiers of lots and an easement may be included to separate them.
(g) Through lots (extending from one parallel street to the other) shall be discouraged to avoid problems between adjoining owners, and to reduce the number of streets.
