Kitsap Regional Library is primarily supported through property taxes (more than 90% of the total library budget). Under Washington law, library levies may be no higher than 50 cents per $1,000 of assessed valuation for operations and maintenance. Library property tax support is also subject to the 2001 statewide Initiative 747, which limits the increase in property tax collections to no more than 1% each year, plus the value of new construction.
