The Clean Water Program performs construction site inspections in addition to investigating urban runoff reports received. During these inspections and investigations, the Clean Water Program looks for proper BMP implementation, evidence of urban runoff, and performs a source determination. If there is an active discharge occurring, the Clean Water Program Investigator will try to establish contact with the contractor or homeowner to cease activities. In addition, the Clean Water Program will generate a Clean Water Education Letter to provide education on urban runoff and prevention practices and describe the issue that was observed with photos that were taken during the investigation. If you received a Clean Water Education Letter, please implement the requests noted by the Clean Water Program. Should you have questions or need assistance, please call the Clean Water Program (858-704-3652) to discuss the urban runoff report further.
