Rates on the application: rain garden $4 per sq ft ($6 income-limited), depave $4 per sq ft of area depaved ($6), cistern draining to landscape $1.50 per sq ft ($3.50), cistern draining to side sewer $0.75 per sq ft ($2.25), green roof $1.25 per sq ft ($3.50), Grattix $1.50 per sq ft ($3.50). Payment is issued after the project is completed. Optional pre-approval holds funds for up to 3 months. Check your address on the King County WaterWorks eligibility map before applying; the cities listed here send wastewater to King County, and the service area boundary does not follow city limits exactly (Stewardship Partners, GSI Mini Grants page and application dated July 2026; last verified October 2026).
