Abstract: Laguna Peak Tire Anchor Wall, Naval Air Warfare Station, Point Mugu, California

TRACY, W. C., M. ADAMS, M. WAHIDUZZAMAN, Santa Barbara County Public Works Department, Santa Barbara, CA

A innovative use of discarded tires in a slope stabilization project (project) has been constructed on the Naval Air Weapons Station at Point Mugu, Califomia, south of Ventura. The project represents a joint Santa Barbara County - United States Navy cooperative effort, and saved the Navy approximately $50,000. The project was designed by the Santa Barbara County Public Works Department, Transportation Division. The project is located on a steep mountainous slope above the Point Mugu Naval facility at an elevation of 1,450-feet.

The success of this project was critical to maintaining radar installation accessed by Laguna Peak Road. Facilities at Laguna Peak are operated by the Range Department of the Naval Air Weapons Station and by the Naval Satellite Operations Center. The transmitter, receiver, and two telemetry antenna buildings above the project site are a vital link of the West Coast support for missile test and evaluation, mission control functions, and Navy fleet operations. In addition, Los Angeles Intemational Airport maintains radar equipment on the peak, and requires the continuous operation of their radar systems for incoming and outgoing aircraft.

The challenges for Santa Barbara County Public Works Department and United States Navy were to recycle discarded tires to stabilize a steep mountainous slope and to refine tentative construction procedures for the building of a tire anchor wall. In the winter season of 1994-1995, a portion of Laguna Peak Road failed due to slippage of a steep mountainous slope.

The Laguna Peak Road project was recently inspected on January 24, 1998 for storm related damage following the recent stomms. The site has experienced 18 inches of rainfall to date this season. The slope and road protected by the tire wall did not sustain any damage or erosion.
