Plan early – the more ready to go your projects are at the time of application, the more likely you are to be in a position to apply for funding when opportunities become available.

Public Works Board – search for funding, training, technical assistance, etc.
GrantStation – searchable funding resource
Municipal Research and Services Center of Washington (MRSC) – Funding Sources for Economic Development – Financial Assistance Programs
