Significant development has taken place in Riverside County in the last several decades resulting in the urbanization of many areas. Urbanization generally increases Urban Runoff volume and velocity of runoff and the amount of pollutants in the runoff.
As development occurs, natural vegetated pervious ground cover is converted to impervious surfaces such as highways, streets, rooftops and parking lots. Natural vegetated soil can both absorb rainwater and remove Pollutants providing an effective natural purification process. In contrast, impervious surfaces can neither absorb water nor remove pollutants, and the natural purification characteristics are lost.
Additionally, urban development can significantly increase pollutant loads as the increased population density causes proportionately higher levels of vehicle emissions, vehicle maintenance wastes, municipal sewage wastes, pesticide, household hazardous wastes, pet wastes, trash, and other anthropogenic pollutants.
To counteract the effects of urbanization, new developments and significant redevelopments follow Low Impact Development (LID) principles and utilize the Water Quality Management Plan (WQMP) template and guidance in the design of their site. See the following pages for more information:
