Water Quality Improvement Plans
The City collaborated with other jurisdictions and stakeholders throughout the San Diego Region to develop Water Quality Improvement Plans (WQIP) for each watersheds within its jurisdiction. The goal of the WQIPs is to protect, preserve, enhance, and restore water quality of receiving water bodies. This goal will be accomplished through an adaptive planning and management process that identifies the highest priority water quality conditions within a watershed and implements strategies to achieve improvements in the quality of discharges from the Responsible Agencies' storm drain systems.
The City of San Diego is the lead on the WQIP development for the San Dieguito, Los Peñasquitos and Mission Bay watersheds. The City is also a participating agency in the San Diego River, San Diego Bay and Tijuana River watersheds. For more information on the plans and annual reporting, please visit the link below:
To estimate the funding need for implementing the WQIP strategies, the City developed a robust cost tool that calculates and organizes the annual cost for each strategy. For more information about the development of the tool, anticipated costs and potential improvements, see the fact sheet below:
To support the development of the WQIPs, the City performed a literature review and accompanying analysis to quantify potential pollutant load reductions associated with certain non-structural best management practices or strategies. The results are summarized in the following technical memorandum:
Jurisdictional Runoff Management Plan
The City's Jurisdictional Runoff Management Plan encompasses citywide programs and activities designed to prevent and reduce storm water pollution within City boundaries. Read more here.
Storm Water Fee Study
The City of San Diego Storm Water Fee Study was completed to meet a requirement in the Settlement Agreement and Release for the City’s Master Maintenance Program and Programmatic Environmental Impact Report. The Agreement stipulates that the City shall complete a fee study, conducted by a third-party expert, within three years of the effective date of the Agreement (Sept. 27, 2013) and shall post the Fee Study on the City Storm Water Division’s website by Sept. 26, 2016.
Watershed Asset Management Plan
The Storm Water Division has prepared the following Watershed Asset Management Plan to identify the broad investments required to maintain the City's storm water management system. The plan is consistent with the City's general asset management practices and is one of the first comprehensive asset management planning efforts in the storm water field that addresses both flood risk management and storm water quality. The Plan incorporates the strategies identified in the Comprehensive Load Reduction Plans also available on this page as a foundation for meeting the requirements and compliance standards of the new Municipal Separate Storm Sewer System (MS4) permit issued by the Regional Water Quality Control Board on May 8, 2013.
Comprehensive Load Reduction Plans
The following Comprehensive Load Reduction Plans (CLRPs) are the second phase of an ongoing effort to identify the projects and funding levels needed to comply with storm water regulations established by the Regional Water Quality Control Board. These updated plans expand on the methodology and rationale presented in the initial CLRP documents filed with the Board on Oct. 4, 2012 (available below). The City will continue to refine the project list and cost estimate presented in these plans and expects to post further updates at a future date. The City encourages public evaluation of these documents and welcomes questions, comments and suggestions for improvements.

Best Management Practices Inspection and Maintenance Workshop
On April 6, 2011, the City offered a free workshop on maintenance practices for Low Impact Development Best Management Practices. The handout may be downloaded from the link below.

Master Storm Water System Maintenance Program
The City of San Diego has adopted a Master Storm Water System Maintenance Program for flood control facilities in neighborhoods across the City. The Master Program will allow the City to better identify flood control channels requiring maintenance services over the next five years. Each fiscal year, the City will identify a small group of channels that have deposits of sediment and overgrowth of vegetation requiring maintenance to restore flood control capacity.
