Los Penasquitos Water Quality Improvement Plan
Agencies involved in the development of the Los Penasquitos Water Quality Improvement Plan (WQIP) include the Cities of San Diego, Del Mar and Poway, the County of San Diego, and the California Department of Transportation. The WQIP is a requirement of updated stormwater regulations adopted by the Regional Water Quality Control Board (Regional Board) according to Order No. R9-2013-0001, as amended by Order Nos. R9 2015-0001 and R9-2015-0100. The ultimate goal of the WQIP is to protect, preserve, enhance, and restore water quality of receiving water bodies. These improvements in water quality will be accomplished through an adaptive planning and management process that identifies the highest priority water quality conditions within the watershed and implements strategies to address them.
The Los Penasquitos Water Quality Improvement Plan was originally submitted to the Regional Board on June 26, 2015, as required by the Municipal Permit. The WQIP was subsequently revised and resubmitted in order to incorporate comments received from the public and the Regional Board. Following further comments, the Regional Board issued an acceptance letter for the Los Penasquitos WQIP on February 12, 2016. The resulting WQIP, appendices, and acceptance letter are available at the links below:

As part of the adaptive management process and in order to discuss watershed-wide goals, strategies, and issues, Copermittees hold monthly workgroup meetings that are also open to the public. These meetings, along with their agendas, meeting summaries, and meeting materials, are linked to below.
