What is a Rain Garden?
A rain garden is a garden designed to function similar to an undisturbed native forest by collecting, absorbing, and filtering stormwater runoff from hard surfaces like rooftops, driveways, patios, and other areas that don’t allow water to soak into the ground. Rain gardens protect and improve water quality, while adding a lovely landscape amenity to your property. Soil type needs to be assessed when considering whether to build a rain garden.
- Can be shaped and sized to fit your yard.
- Are constructed with specially formulated soil mixes that allow water to soak in rapidly and support healthy plant growth.
- Can be landscaped with a variety of plants to fit the surroundings.
A Little Garden Makes a Big Difference
Carefully designed and constructed for optimum function – rain gardens are a simple and effective solution for on-site stormwater management.
What are the Benefits of a Rain Garden?
Rain gardens can protect water quality and aquatic life in local streams, lakes and Puget Sound by:
- Filtering oil, pesticides, bacteria, fertilizers and other pollutants from stormwater runoff,
- Helping to capture and infiltrate stormwater that may be running off of your property, while recharging the local groundwater thus helping to keep streams flowing even during the dry season.
- Reducing localized flooding in neighborhoods and erosion along streams and shorelines,
- Providing habitat for wildlife while beautifying landscapes.

Each jurisdiction is sponsoring a Rain Garden Incentive Program that will reimburse selected applicants for expenses such as plants or compost upon the successful construction of their rain garden.
