Storm Water Program

The Storm Water Division regulates and enforces Clean Water Act standards as prescribed by the National Pollutant Discharge Elimination System (NPDES) permit program. The goal of the program is to keep our waterways and community clean by reducing pollutants from entering the City's storm drain system.


The sanitary sewer system drains to a treatment plant. The storm sewer (or storm drain) system does not. Everything that goes into storm drains goes out to Paradise Creek, the Sweetwater River, San Diego Bay, and other local waterways without any treatment.

Difference between Storm Drain and Sanitary Sewer


Examples of actions the City takes to reduce pollution and protect our waterways include street sweeping, storm drain cleaning, and inspecting businesses and construction sites to make sure they are following best practices to reduce pollution.

Storm Water Requirements Overview

Information about storm water requirements are provided at the links below; for more information, see the City's Jurisdictional Runoff Management Program (JRMP).

    Updated Jurisdictional Runoff Management Program (JRMP) 

    The Jurisdictional Runoff Management Program (JRMP) is the City of National City's approach to improving water quality in its creeks, rivers, and San Diego Bay by reducing discharges of pollutants to the municipal separate storm sewer system (MS4). The City's MS4 conveys runoff from rain, over-irrigation, and other sources of water to receiving water bodies without first being directed to a treatment plant.

    This JRMP has been prepared in response to the new MS4 Permit issued by the San Diego Regional Water Quality Control Board (Order No. R9-2013-0001, as amended by R9-2015-0001). The 2013 MS4 Permit requires the City of National City and the other 20 municipal agencies in San Diego County to prepare both jurisdictional and watershed scale plans that detail how they will comply with the new storm water requirements. The JRMP is an update to the City's 2008 Jurisdictional Urban Runoff Management Program (JURMP), which was prepared in response to the 2007 MS4 Permit. The Engineering & Public Works Department has led the City's efforts to update the JRMP.
