Clean Water Landscaping

Got a green thumb? Like do-it-yourself projects? These time-tested stormwater features will beautify your yard and fight pollution at the same time.

Native Plants

Native plants can provide an attractive, cost-effective and environmentally friendly alternative to traditional lawns and landscapes. In addition to providing valuable food and habitat for native butterflies, birds and other wildlife, native plants have deep roots that soak up stormwater, break up compacted soil and help infiltrate runoff into the ground.

Permeable Pavers

Permeable pavers allow stormwater to soak into the ground by running down into the gaps between pavers. The pavers are installed over one or more base layers of stone and/or sand. In addition to providing a stable base for the pavers, these base layers provide drainage capacity and allow runoff to infiltrate the ground beneath.

Rainbarrels

Rainbarrels capture stormwater runoff from rooftops and store it so that it can be reused for irrigating plants during dry spells. In addition to reducing the amount of potable water used for watering plants, rainbarrels also help add capacity to city stormsewer systems by capturing part of the first flush of a rain event.

Raingardens

What is a Stormwater BMP?

The projects and features on this web page are all examples of stormwater best management practices (BMPs) — a technical term for landscape features that capture, clean and absorb stormwater runoff. In urban areas, stormwater BMPs are valuable not only because they help protect water quality, but also because they provide habitat and create green space that supports healthy lifestyles and public enjoyment.

Another way to think of stormwater BMPs is as sustainable drainage. This video lays out the basic concept of sustainable drainage and highlights its many benefits:
