Supervisor Don Horsley, engineers and representatives from the Los Trancos Woods and Vista Verde community were gathered there for a ribbon-cutting. Ramona Road is a link to essential outside services for this community within unincorporated San Mateo County.
The heavy rains in December 2012 reminded residents of a 1983 washout that closed Ramona Road for weeks, and forced residents to use narrow rural roads to get in and out of the community, said community residents Ruth and Gerry Nelson, who wrote a chronology on the project.
With the past in mind, community volunteers earlier this year organized a technical analysis of the land around 281 Ramona Road using $25,000 from the local Los Trancos County Water District.
With the analysis complete, the county Department of Public Works took immediate preventive measures and mapped out a plan to fix the problem, residents said. Supervisor Don Horsley, who represents the community on the Board of Supervisors, helped arrange a declaration of emergency, which put the project on a fast track.
The county began work on the wall in July and spent between $200,000 and $250,000, resident Ken Kormanak told the Almanac.
The retaining wall, which includes 15 50-foot steel I-beams sunk vertically into the ground, runs 87 linear feet along the side of the road and is 21 feet high, Mr. Kormanak said. Two hundred fifty bolts hold the wooden beams of the wall in place.
