Information for Shoreline

The Surface Water Utility offers rebates up to $2,000 for Shoreline home or business owners to install a rain garden or native vegetation landscaping on their property.

These features are part of a natural approach to storm water known as low-impact development, which seeks to mimic forested conditions by allowing rainwater to soak into the soil.

What is a Rain Garden?

A rain garden is a planted, shallow depression filled with layers of soil and organic material that collects, absorbs, and filters stormwater runoff from roof tops, driveways, patios, and other areas that don’t allow water to soak in. Rain gardens can be shaped and sized to fit your yard, and can be landscaped with a variety of native plants to fit the surroundings. The average home rain garden naturally filters 30,000 gallons of water per year, enough to fill a bathtub 600 times! 

What is Native Vegetation Landscaping?

Native vegetation landscaping is the removal of hard surfaces such as pavement or turf grass and replacing it with native plant species that have deeper root systems and amended soils. In addition to laying down mulch, this technique slows down the flow of stormwater runoff, allows for the groundwater to recharge, and filters out pollutants.
