Cottonwood Creek: Project Overview

In July 2004, the County of San Diego received a grant from the State Water Resources Control Board (SWRCB) to remove exotic (non-native) plants and revegetate with native plants along portions of upper Cottonwood Creek located in the Tijuana River Watershed. The project includes two portions of Cottonwood Creek. The first portion is approximately a two-mile stretch from Barrett Reservoir to State Route (SR) 94 and the second extends from approximately Buckman Springs Road to just above Morena Reservoir. Funding for the project was provided in the form of a Proposition 13 Grant. Proposition 13 was approved by California voters in 2000 that authorized the State of California to sell bonds to support water resource project funding. 

Project Location MapCoordination on the project was led by the County of San Diego Department of Public Works-Watershed Protection Program. The County contracted Rick Engineering Company to oversee the implementation of the project as well as provide Aerial Imagery acquisition, GPS (Global Positioning System) field location service and Geographic Information Systems (GIS) map production services. Additional consulting services that were coordinated through Rick Engineering Company included Tierra Environmental who led the aspects of the invasive removal program, and project monitoring. RECON Environmental provided revegetation and reporting services.

Key Components of the project included:

1. Mapping and Planning
2. Removal and Revegetation 
3. Outreach
