Development Standards—Design Requirements | Town Center
for pedestrian-oriented streets could cover an entire street, a single block, or a portion of a block, depending upon the area. Pedestrian-oriented street designations are intended for areas where a concentration of pedestrian activity is desired. See SDC 21.07.060A.3.a. for related development frontage standards. iii. Mixed-use streets, which are all other new streets besides connector roads and pedestrian-oriented streets within the TC-A zones. These are localized streets which should include generous sidewalks, street trees, bioretention, on-street parking (to the extent possible), and slow moving traffic. iv. Residential streets, which are all other new streets besides connector roads within the TC-B and TC-C zones. These are localized streets within residential neighborhoods and should contain sidewalks, planting strips with street trees or bioretention, on-street parking on one or both sides, and slow moving traffic. v. Alleys are encouraged where useful to access parking or service areas. c. Maximum Block Dimensions for Individual Development. For an individual development, unless otherwise stated in a unified zone development plan, the maximum block length in any direction is 480 feet and maximum block perimeter is 1,400 feet. Departures are permitted in the TC-A zones subject to unified zone development plan approval and compliance with the Town Center Plan’s goals and policies. Departures
for streets in all other Town Center zones shall be considered by the director based on one or more criteria listed below. i. Topography, right-of-way, existing construction or physical conditions, or other geographic conditions impose an unusual hardship on the project applicant, and an equivalent alternative which can meet the Town Center Plan’s goals and policies is available; ii. A departure provides the opportunity for a public open space or other public amenity that would otherwise not be possible; iii. The location of institutional or other similar uses requires a larger block size; and/or iv. A private internal road(s) or pedestrian route may be used to meet cross circulation standards as determined by the director per the following: a) Adjacent properties do not rely on applicable roadway for primary vehicular access; b) Roadway should be designed to look and function like public streets (planting strips, street trees, sidewalks, and parallel parking, where appropriate per the director); and c) Roadway or pedestrian route shall be accessible to the public.
