San Luis Rey Water Quality Improvement Plan

The San Luis Rey Watershed Managment Area Water Quality Improvement Plan
The City of Oceanside, City of Vista, County of San Diego and California Department of Transportation are the participating agencies that developed the San Luis Rey Water Quality Improvement Plan (WQIP). This plan is required by new stormwater regulations adopted by the Regional Water Quality Control Board (Regional Board) Order No. R9-2013-0001, as amended by Order R9-2015-0001. The goal of the WQIP is to protect, preserve, enhance, and restore water quality of receiving water bodies. The goal 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 achieve improvements in the qaulity of discharges from the responsible agencies storm drain system.

Current Events
The San Luis Rey Participating Agencies hold regular workgroup meetings that are open to the public. See Workgroup Meetings section below for meeting agendas, materials, and summaries. The 2016 Workgroup Meetings will be held at the City of Vista Civic Center in the Adobe Room, at 200 Civic Center Drive, Vista, CA, from 10 a.m. to 12 p.m. the third Tuesday of each month.

Final, Accepted San Luis Rey Water Quality Improvement Plan (March 2106)
The San Luis Rey Water Quality Improvement Plan was originally submitted to the Regional Water Quality Control Board on June 26, 2015, as required by the Municipal Permit. The WQIP was subsequently revised in September 2015, based on comments received from the public and the Regional Board, and again in March 2016 based on comments from the Regional Board. The Regional Board issued an acceptance letter for the San Luis Rey WQIP on February 12, 2016. The final WQIP and acceptance letter are available at the links below.
