A Plexiglass case filled with plants, soil and “rain on demand” is giving City Hall visitors a fun lesson on how landscaping can stop pollution from getting into creeks and the Bay. Visitors push a button to activate a sprinkler system simulating rain. The water soaks into the ground, seeps through plant roots and layers of soil, and eventually trickles out via a PVC pipe.
In suburban areas such as Walnut Creek, buildings, streets and pavement now cover much of the land. Rainwater runs off these hard surfaces directly into the storm drain systems, taking pollutants with it. The runoff moves rapidly through the system into creeks, causing flooding, destabilized stream banks and destruction of creek habitat.
Effective landscaping can be used to stop this rapid runoff. As the rain soaks into the ground, pollutants from the atmosphere are absorbed through contact with soils and vegetation.
Under the City ’s Clean Water permit, certain development projects are required to incorporate these landscaping “bio-swales” into their plans.
Managing runoff from a single development site may seem inconsequential, but by changing the way most sites are developed, we may be able to preserve and enhance our stream ecosystem in urbanizing areas.
