What is a Watershed?
A watershed is a basin-like landform that collects water whenever it rains or snows. Through gravity, water is channeled into soils, groundwater, creeks, streams, lakes and eventually drains into larger bodies of water such as the rivers and eventually the ocean.
The important thing to remember is that we all live in a watershed and whatever we do to the land affects water quality of the all communities living downstream. Water is a universal solvent and is affected by the land it travels across and the soil that it travels through.
The City of Irvine happens to be in the Newport Bay Watershed, which includes the San Diego Creek (a flood control channel). San Diego Creek is the main tributary that drains into Upper Newport Bay. Smaller tributaries include Serrano Creek, Borrego Canyon Wash, Agua Chinon Wash, Bee Canyon Wash, Peters Canyon Wash, Sand Canyon Wash, Bonita Canyon Creek and the Santa Ana Delhi Channel.

What can my business do to prevent stormwater pollution?
One of the most common types of pollution from businesses is contaminated water runoff, usually from cleaning and maintenance activities. Simple Best Management Practices (BMPs) can prevent stormwater pollution, and it’s good business practice to show your clients and customers your concern for your local community and the environment.
Review the list of materials below for more information on how your business can prevent Stormwater pollution. For a list of additional brochures, please click here.
Automotive fluids such as oil, grease and anti-freeze along with other harmful materials-like asbestos worn from brake linings and zinc from tires-significantly degrade water quality when they make it into waterways. Along with being an issue for public safety, these materials are detrimental to marine life.

Commercial Landscape Maintenance
When it rains, any yard waste, fertilizer or chemicals such as pesticides used in landscape maintenance that are swept into the stormdrain system can lead to waterways like the ocean. Grass clippings and other plant waste can clog the stormdrain system, while lawn and garden chemicals can have adverse affects on marine life and water quality.

Food Service Industry
Food waste, grease, cleaning fluids, mop water and trash from restaurant operations often make their way into the stormdrain system and do not get treated before flowing into local waterways. Click here for stormwater pollution prevention brochures for the food industry.
General Industrial and Manufacturing Businesses
