Otherwise, a text list of the maps is included below.
The erosion information presented on the coastal erosion maps is placed
in a geologic context on twenty-six coastal geology maps using the same
bases as the coastal erosion maps. The geology maps generalize coastal morphology
and geology by means of schematic cross sections. Natural coastal processes
such as cliff erosion, slope failure, wave erosion, landslides, block falls,
debris slides, and cave collapse are illustrated diagrammatically on the
cross sections. Ultimately, wave erosion is the primary or initiating erosive
process along the San Mateo County coast. Waves erode the base of the sea
cliffs or coastal bluffs, thus oversteepening and destabilizing the slopes
above. Landslides, debris slides, and block falls are secondary erosive
agents that move loosened rock material down the slopes to the beaches below,
where the material is eventually eroded away by wave activity. Along most
of the San Mateo County coast groundwater that seeps from the cliff face
softens and loosens even otherwise resistent bedrock material, thus contributing
to the erosional process.
