Application process

There are two different tracks for applying for grants: the competitive track and the council-allocated track. Both tracks have the same eligibility criteria, and similar applications, but the review and selection process are different. Proposals for the council-allocated track are selected by King County Council.* WaterWorks staff administer all grants after they are awarded, and all grants have the same reporting requirements.

*Contact your councilmember’s office directly for questions about the WaterWorks council-allocation review or selection process. For a map of council districts and contact info, visit the council district finder.
