Coastal Erosion Maps

Notes describing the moderate to severe coastal erosion in San Mateo County during the 1982-83 El Niño are compiled on twenty-six page-sized maps at a scale of 1:12,000. The bases for these maps are enlarged portions of the 7 USGS 7.5' topographic quadrangles that cover the coastal area of San Mateo County. Notes describing critical erosion are colored red, and those describing noncritical erosion are colored black. The areas of critical erosion are summarized separately on a smaller-scale map (see critical erosion map).
