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.

Application materials and submission FAQ

Yes. However, be aware that it is unlikely that more than one proposal will be funded in the same cycle through the competitive track.

Yes, but since you can’t get funding from both tracks for the same body of work, the best practice is to submit proposals for different projects. Proposals that are not funded or partially funded through the competitive process are shared with council, and may be funded through that track in this way.
