in effectA. Minimum sidewalk widths are established for certain streets by Map 1C [5] . 1. If a new structure is proposed on lots abutting these streets, sidewalks shall be widened, if necessary, to meet the minimum standard. The sidewalk may be widened into the right-of-way if approved by the Director of Transportation. 2. Sidewalk widths for certain streets within PMM, PSM, IDM, and IDR zones are addressed by Special Review or Historic District regulations. On a street within the International Special Review District for which a sidewalk width is designated on Map 1C, the minimum sidewalk width identified by Map 1C may be reduced if it is determined that a reduced sidewalk width would better meet the goals and objectives of the International Special Review District identified in Section 23.66.302 . Final approval for the reduced sidewalk width will be made by the Director of Transportation upon recommendation by the Director of Neighborhoods. B. A setback or dedication may be required in order to meet the provisions of Section 23.53.030 , Alley improvements in all zones.
