Geologic Hazard Susceptibility and Cost Assessment for Rural San Mateo County, California

A 2000 USGS publication provides geospatial data on deep-seated landslide and debris flow susceptibility for rural western San Mateo County, California. The digital database includes 43 plotfiles and 12 ARC export files with hazard maps derived from slope data and previous geologic mapping. It also estimates possible costs for investigating and mitigating these hazards.

Use Cases

• Assessing property-level landslide and debris flow risk based on the provided susceptibility maps.
• Estimating potential investigation and mitigation costs for geologic hazards on a specific property.
• Planning land use and infrastructure (e.g., roads, creeks) to avoid areas with high sediment runoff from landslides.
• Supporting environmental impact studies, such as analyzing effects of landslide sediment on local fish populations.

Strengths

• Includes 43 distinct plotfiles covering slope maps, orthophotos, geologic maps, and landslide inventory/susceptibility maps.
• Provides 12 ARC export files of supporting digital data for GIS analysis.
• Features an interactive website allowing users to locate their property and overlay hazard maps.
• Maps are derived from integrating slope data with previous detailed geologic and landslide mapping.

Limitations

• Last updated 2000-12-31 23:59:59.999000; freshness should be verified.
• The spatial resolution is limited to 1:24,000 scale by the source maps.
• Column-level documentation is absent; field semantics must be inferred after download.
