Stormwater carries untreated water runoff directly into creeks and rivers and, by doing so, impacts our environment. Improper disposal of wastes, such as oil, paint, fertilizer and pesticides will pollute the stormwater and destroy plants, endanger wildlife and affect drinking water. Never dump materials, including grass clippings, into any storm drain or drainage canal, and be sure to keep any catch basins on your property free of grass clippings and debris.
