The City of Orange is mandated by federal NPDES permit R8-2009-0030 to implement stormwater runoff management programs. All development projects must comply with the city's Local Implementation Plan under the Orange County Drainage Area Management Plan.
Under the federal National Pollutant Discharge Elimination System permit R8-2009-0030, the City of Orange implements stormwater management programs described in the Drainage Area Management Plan (DAMP) and Local Implementation Plan (LIP). All projects requiring discretionary and some ministerial approvals must prepare a Water Quality Management Plan per Chapter 7 of the DAMP/LIP. The city maintains a storm drain system separate from the sanitary sewer, and pollutants entering storm drains flow untreated to Santiago Creek and ultimately the Pacific Ocean. Low Impact Development (LID) techniques such as bioswales, permeable paving, and rain gardens are encouraged or required for new development. Residents must not discharge pollutants including motor oil, paint, pesticides, or debris into storm drains.
Illegal discharges to the storm drain system violate federal and state clean water laws. Penalties include fines up to $10,000 per day for ongoing violations. Business violations may result in permit revocation.
