Chollas Creek Dissolved Metals TMDL Implementation Plan
The Chollas Creek Dissolved Metals Total Maximum Daily Load (TMDL) Implementation Plan Stakeholders page
serves as a resource for interested community members, agencies and other stakeholders. This site provides an opportunity
to learn about the TMDL process, review draft documents and check project status. (Note: for information that describes the TMDL, please see "TMDLs" section below.)
The Chollas Creek Dissolved Metals TMDL Implementation Plan (hereafter referred to as "Implementation Plan") was
developed by the jurisdictions and agencies named in the TMDLs including the City of the San Diego, the City of La Mesa,
the City of Lemon Grove, the County of San Diego, U.S. Navy, the Port of San Diego, and Caltrans.
The purpose of the Implementation Plan is to provide the basis and strategy to reduce dissolved metals loading and other
constituents of concern in storm water and urban runoff that may be impacting the beneficial uses of Chollas Creek. The Implementation
Plan identifies projects to be implemented in the first 5-year phase of the program to meet these goals. The Implementation Plan
is tentatively scheduled to be submitted to the San Diego Regional Water Quality Control Board in early October 2009.

Final Draft Chollas Creek Dissolved Metals TMDL Implementation Plan

Additional Information
Chollas Creek Watershed
The Chollas Creek Watershed is located south and east of downtown San Diego in a highly urbanized portion
of San Diego County. The watershed drains approximately 30 square miles via two main tributaries, the North
Fork and the South Fork, and discharges into San Diego Bay. Except for the downstream 1.2 mile tidal prism area,
Chollas Creek is an ephemeral stream which usually only flows during rainy conditions. The map below highlights the Chollas Creek
Watershed boundaries, jurisdictional boundaries of the responsible agencies, and the City of San Diego's community plan areas.
TMDL
A TMDL is a "pollution budget" for an impaired waterbody, such as Chollas Creek. A TMDL defines the maximum amount of a
pollutant the waterbody can safely receive while meeting the water quality objectives identified in the San Diego Basin Plan.
There are four adopted TMDLs for Chollas Creek: the pesticide (diazinon) TMDL, the dissolved metals TMDL (for copper, lead and zinc).
In addition, a draft TMDL for indicator bacteria is currently being revised. This Implementation Plan is designed to meet the requirements
of the metals and bacteria TMDLs over the 20 year allowed implementation period. The Implementation Plan uses an integrated approach to achieve this goal.
