CAM 329, Environmentally Critical Areas Administrative Conditional Use Permit—Application Instructions and Submittal Requirements


City of Seattle regulations for Environmentally Critical Areas (ECAs) set strict platting standards (see SMC 25.09.240) on parcels containing riparian corridors, shoreline habitat, shoreline habitat buffers, wetlands, wetland buffers, and steep slopes. In circumstances where the presence of an ECA or buffer limits the number of lots or dwelling units that may be developed on a parcel in a single family zone, applicants may apply for an ECA Administrative Conditional Use Permit to allow them to count environmentally critical areas and their buffers in calculating the maximum number of lots and units allowed on the parcel (see SMC 25.09.260). DPD may modify lot size and setback requirements or allow more than one dwelling unit per lot as necessary to allow for an increase in the number of lots and units on the portion outside the critical area.
