The Capital Improvement Program is Thurston County government’s six-year plan of community investment projects for unincorporated areas of Thurston County. This plan ensures that the County government's public facilities and services keep up with population growth. The plan is reviewed and updated annually with the County's annual budget, as Appendix G of the County’s Comprehensive Plan.
The work is mandated by the Washington State Legislature through its Growth Management Act (RCW 36.70A.020) which requires county Comprehensive Plans, to plan for specific facilities and financing methods, and to make regular plan adjustments based on current budgets and community needs.
The planning document includes estimated proposed dates, costs, and methods of financing roads, bridges, sewers, parks, drinking water facilities, stormwater, garbage disposal, recycling, government and public services buildings. This plan is long-range in scope, because implementing capital improvements typically requires multi-year commitments of financial resources. The planning is also complex, requiring each department of the County to focus on projects under their jurisdiction, while coordinating with the BoCC and other County departments.
