Abstract

This report presents data on the location and cost of damage related to landslides in the San Francisco Bay region during the rainy season of 1972-73 (figs. 1 and 2). By showing the general location of landslides that caused damage during that season, the report also shows which parts of the region have the most severe problems. These data supplement earlier reports by the U.S . Geological Survey on the damage caused by landsliding throughout the bay region during the rainy season of 1968-69 (Taylor and Brabb, 1972), in Contra Costa County from 1950 to 1971 (Nilsen and Turner, 1975), in Alameda County from 1940 to 1971 (Nilsen and others, 1975), and in the northeastern part of the city of San Jose from 1967 to 1971 (Nilsen and Brabb, 1972).

The nine San Francisco Bay region counties are included in this investigation: Alameda, Contra Costa, Marin, Napa, San ,Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Landslide costs for these counties during the 1972-73 rainy season (table 1) were at least \$9,716,284. Of this total, $3,284,918 was direct loss of or damage to private property, mainly by lowering the property market value, and \$6,431,366 was for public property, chiefly for repair or relocation of roads. The data used to compile these costs are incomplete, thus the total cost could be significantly greater.
