Undeveloped streets—Modification of certain development standards.

Seattle Mun. Code § 23.40.030

in effect

For purposes of determining yards, setbacks and whether or not a lot is a corner lot or a through lot, the Director may allow an abutting street to be treated as an alley if the Director finds that the lot abuts on at least one (1) other street suitable for vehicular use or is served by an access easement meeting the standards of Section 23.53.025 , and that the following criteria are met: A. The street in the block where it abuts the lot is wholly undeveloped, is unpaved, or is developed with a roadway less than twenty (20) feet in width; and B. The street provides either no access or only secondary access to those lots to which it abuts; and C. The development proposed for the lot does not require improvement of the street and no plans to develop the street are on file with the City; and D. Existing streetscapes and development patterns are not disrupted. (Ord. 115326 § 3, 1990.)
