Notice of availability of the Final Environmental Impact Statement/Environmental Impact Report on a proposed sediment retention system in the Goat Canyon Creek and watershed at the Tijuana River National Estuarine Research Reserve, Imperial Beach, California.


Pursuant to the National Environmental Policy Act and the California Environmental Quality Act, the National Ocean Service (NOS), in cooperation with California Department of Parks and Recreation and California Coastal Conservancy, has completed the preparation of a joint Final Environmental Impact Statement/Environmental Impact Report (FEIS/EIR) addressing the potential effects on the human and natural environment that may result from construction of sedimentation, flood control and other facilities within and adjacent to Goat Canyon, and the elevation and/or realignment of Monument Road through Border Field State Park lands. The purpose of these proposed facilities is to enhance the existing Goat Canyon Creek and its natural habitat communities, including the Tijuana River Estuary, through the management of sediment within the canyon and on the adjacent alluvial fan.

The proposed project is in conformance with the Final Goat Canyon/Canon de los Laureles Enhancement Plan prepared by the Southwest Wetlands Interpretive Association (SWIA) and California Coastal Conservancy. As a result of the construction of sedimentation basins, it is anticipated that Goat Canyon Creek, its watershed, and the Tijuana River Estuary will be enhanced.

The Final EIS/EIR is available for public review. All comments received, including names and addresses, will become part of the administrative record and be made available to the public. NOAA is not required to respond to comments received as a result of issuance of the FEIS/EIR, however comments will be reviewed and considered for their impact on issuance of a Record of Decision (ROD). The ROD will be printed in the Federal Register some time after the close of the public review period.


The review period for the joint Final EIS/EIR will end on Monday, February 4, 2002. All written comments received by this deadline will be considered in the preparation of the ROD.


Written comments on the joint Final EIS/EIR should be sent to Nina Garfield, NOAA, Estuarine Reserves Division, SSMC-4, 11th Floor, 1305 East-West Highway, Silver Spring, Maryland, 20910-3281.

Goat Canyon Creek is located in the far western portion of the greater Tijuana River Watershed approximately one mile inland from the Pacific Ocean. The watershed is characterized by steep slopes, sandy soils with cobbles, Start Printed Page 569pockets of native coastal sage scrub, riparian vegetation, and a high level of human-induced disturbance, especially during the last 20 to 30 years. A prominent result of changes in the watershed has been a significant increase in sediment yield in response to higher volumes of runoff and an increased sediment supply throughout the watershed. Increased sedimentation has adversely affected the local habitat communities of Goat Canyon and downstream within the Tijuana River Estuary. By the mid-1980s, it was estimated that erosion and sedimentation had resulted in the loss of 30 acres of intertidal wetland area in the Tijuana River Estuary. The composition and distribution of native habitat communities along the creek and on the alluvial fan have been altered, as has the morphology of the creek. Further, during storm events, sediment is deposited on Monument Road, which in turn blocks public access to Border Field State Park and impedes the U.S. Border Patrol.

On August 10, 2000, the National Ocean Service published in the Federal Register a Notice of Intent to prepare a joint Environmental Impact Statement/Environmental Impact Report (Vol. 65 No. 155, 48971-48972). The stated intent of the proposed project was to enhance the existing Goat Canyon Creek and its natural habitat communities, including the Tijuana River Estuary, through the management of sediment within the canyon and on the adjacent alluvial fan. A notice announcing the availability of the draft EIS/EIR was published on October 12, 2001.

The final EIS/EIR examines the potential effects of the No Project Alternative and four project alternatives for construction of a sedimentation retention system within Goat Canyon and the alluvial fan. NOAA has identified Alternative D-1 as the Preferred Alternative based on an evaluation of the comparison of the impacts between the alternatives.

Alternative D-1 features an in-canyon diversion structure and sedimentation basin system consisting of two basins in series to capture the flow in Goat Canyon Creek. The system has been designed to contain the full 100-year flood event. The Preferred Alternative also involves construction of access roads around the basins, staging areas adjacent to the basins, a visual berm located between the basins and Monument Road, improvements to part of Monument Road and a multi-purpose trail, and creation of wetland habitat. The Preferred Alternative would be the most efficient at capturing sediment and would result in the least impacts to sensitive wetland habitats and endangered species.
