About the RainScapes Program
The King County RainScapes partners with home and business owners to fund and install GSI features, like rain gardens, cisterns, and native plant landscaping, on their property.
This program is for properties in unincorporated King County, where there are currently little or no built-in rainwater runoff control features. GSI allows us to tackle flooding and water quality problems in these areas while bringing extra benefits to property owners and communities.
GSI is a great tool for property owners who want to beautify their landscaping and property, save money, and help prevent flooding and water pollution.
How it works
Here's everything you need to know about how the RainScapes Program works:
Cost and affordability
- Private Properties: Construction costs are 100% covered by King County during the program's current pilot phase. Maintenance costs are also 100% covered for the first year after construction is done.
- Commercial properties: Owners may receive a discount on Surface Water Management fees included in property taxes, based on the amount of rainwater treated by GSI on the property.
Technical support and coaching
- King County will provide support and coaching for property owners, so that you feel confident maintaining your new GSI feature.
- Technical assistance is available if you have any questions about or problems with your new feature.
- King County engineers come up with designs that work for the property owner.
- King County manages hiring construction teams and contractors to do the work.
Requirements for property owners
- After the first year of fully-paid maintenance, property owners are responsible for maintaining the GSI feature on their property.
- Property owners are expected to disclose information about the GSI feature if/when the property is sold.
- Commercial property owners will only receive discounts on stormwater management fees as long as the GSI feature is maintained.
Types of GSI features offered
GSI often uses some of the simplest and most powerful tools available to capture and naturally filter water: plants, trees, and soil.
