The bill amends existing laws regarding stormwater control facilities and the jurisdiction of counties in Washington State. It allows counties to finance, acquire, construct, develop, improve, maintain, and operate various facilities, including stormwater control facilities, either independently or in collaboration with other governmental agencies. A significant addition is the requirement for counties to notify and consult with diking or drainage districts when extending or improving stormwater control facilities that interact with these districts. Furthermore, it establishes that diking or drainage districts can accept completed stormwater facilities for maintenance and operation, integrating them into their systems.

Additionally, the bill introduces provisions for the financial management of stormwater control facilities. It allows counties to set rates and charges for services related to these facilities, with specific considerations for benefits received and land use characteristics. Notably, it mandates a minimum 10% reduction in rates for new or remodeled commercial buildings that implement rainwater harvesting systems. Starting in fiscal year 2024, counties may also deposit service charges collected for stormwater facilities into the revenue accounts of diking or drainage districts, enhancing their financial resources for maintenance and operation.
