Thurston County Storm and Surface Water Utility Rates

All property owners in unincorporated Thurston County pay Storm and Surface Water Utility rates through their property taxes. The rates vary depending on  the property's square feet of impervious surface, and also on whether the property is located within the regulatory boundaries of "NPDES Phase II." (This refers to National Pollutant Discharge Elimination System Phase II, a federal regulation that requires Thurston County and other jurisdictions of a certain size to adopt stormwater-management programs to reduce the amount of pollution that enters water bodies.)
