Seattle Rockeries protects Puget Sound's water quality by building rockeries and rain gardens. A rockery or rain garden is a shallow area filled with wetland vegetation designed to store and treat stormwater runoff before it reaches Seattle sewer systems. Rockeries and rain gardens act as collection areas for rainwater during Seattle storms and allowing it to soak into the ground rather than into the local water system.
Rockeries and water gardens should be installed perpendicular to the slope of your yard at the lowest area. Rockeries should be located in full or partial sunlight to assist drainage and evaporation. Water gardens are not meant to form ponds they are meant to seep into the soil.
City of Seattle RainWise Rebate Program
The City of Seattle is encouraging residents to reduce stormwater runoff through its RainWise Program. If you live in an area known for “combined sewer overflows”, you may be eligible for rebates when you hire a trained RainWise contractors to install a rain garden or cistern on your Seattle property.
If you qualify, the City of Seattle will pay up to 100% of the cost of installing rain gardens and cisterns, based on how many square feet of roof runoff is controlled. For more information about the RainWise program and to find out if you qualify, visit the following links:
