A Watershed Urban Runoff Management Program (WURMP) has been actively implemented in the San Diego Bay Watershed Management Area (WMA) since January 2002. The Port of San Diego, as the lead jurisdiction, has collaborated with the City of Chula Vista, City of Coronado, City of La Mesa, City of Lemon Grove, City of Imperial Beach, City of National City, City of San Diego, and the County of San Diego in the preparation of the San Diego Bay WURMP document to comply with the
The San Diego Bay WURMP document developed under Municipal Stormwater Permit R9-2007-001 has incorporated many of the programs that were initially developed under the previous Permit (2001). These programs provided the initial structure for addressing urban runoff related problems on a watershed scale. The purpose of the current WURMP is to cooperatively work together through collaborative strategic planning with the goals of decreasing the sources and reducing the discharge of pollutants from the MS4 that have been identified as causing high priority water quality problems. The WURMP provides guidance and coordination for water quality, education, land use planning activities, and program implementation to efficiently achieve the greatest protection of beneficial use of receiving water bodies.
Due to the size and diverse nature of the San Diego Bay Watershed, it has been divided into of three individual sub-watersheds: Pueblo Watershed, Sweetwater Watershed, and Otay Watershed. The San Diego Bay Copermittees will work together to identify, implement, and assess appropriate watershed water quality and education activities to properly target high priority water quality problems and their sources within these sub-watersheds. Annual assessments of water quality through various monitoring programs during both wet and dry seasons provide results that are evaluated and placed within a historical context for trend analyses, which help determine whether or not watershed activities are working effectively to reduce and prevent water pollution.
