Notes: [1] Plan district, overlay zone, or other development standards contained in Title 17C SMC may supersede these standards. [2] See SMC 17C.111.210 for applicability of minimum and maximum density standards in the residential zones. [3] Development within Airfield Overlay Zones is further regulated as described in SMC 17C.180.090, Limited Use Standards. [4] Requirements associated with driveways such as minimum approach separation and driveway coverage maximums may limit driveways on narrow lots. [5] Lot and building coverage calculation includes all primary and accessory structures. [6] Building coverage for attached housing is calculated based on the overall development site, rather than individual lots. [7] Developments meeting certain criteria relating to transit, Centers & Corridors, or housing affordability are given a bonus for building coverage. See SMC 17C.111.225 for detailed eligibility criteria. [8] Projects may exceed impervious coverage requirements by including an engineer’s drainage plan in submittals, subject to review by the City Engineer as described in SMC 17D.060.135. “ADC” means Area of Drainage Concern. [9] Projects in the RMF and RHD zones that are exempted from review under the Spokane Regional Stormwater Manual shall follow the impervious coverage requirements of the R1 zone.
