The City of Solvang has published an introduction to the Solvang Storm Water Management Program for homeowners and business owners.

Most people believe that the largest source of water pollution in urban areas comes from specific sources such as factories and sewage treatment plants. In fact, the largest sources of water pollution comes from city streets, neighborhoods, construction sites, and parking lots.

This type of pollution is sometimes called "non-point source" pollution. This pollution is spread to our water bodies and natural habitats as a result of run-off, either as a result of rainfall (storm water) or excessive water use (urban).
