Pollutants associated with construction (sediment, paints, concrete, stucco, trash, etc) find their way into our storm drain system. These pollutants eventually enter our local creeks and alter the water quality, causing long-term impairments that create environmental challenges.

Ordinance Enforcement
In order to prevent pollutants from leaving construction sites, the City of Temecula enforces its Grading, Erosion and Sediment Control Ordinance and the standard notes for Erosion and Sediment Control in accordance with the City's Municipal Separate Storm Sewer System (MS4) Permit, regardless of the size of the project.

State Water Resources Control Board
In addition, the State Water Resources Control Board (SWRCB) requires projects that disturb one acre or more of land due to construction or demolition activities, or projects that result in less than one acre of disturbance but are part of a larger common plan of development of one or more acres of land disturbance, to obtain coverage under the State Construction General Permit. Soil disturbance activities include clearing, grubbing, disking, grading, excavating, or stockpiling. This Permit requires a Storm Water Pollution Prevention Plan (SWPPP), routine implementation of pollution prevention measures (Best Management Practices), water quality monitoring, employee training, and self-directed inspections.

Regardless of the site's size, the City and the Regional Water Quality Control Board conduct routine and frequent inspections to ensure that the project is in full compliance with Federal, State, and local regulations.
