Example Project: Geologic Hazard Investigation  

Santa Cruz County – Aptos – Fern Flat Road

Allterra evaluated Geologic Hazards affecting a proposed residential construction project on Fern Flat Road in Aptos, an area known for strong seismic shaking and slope instability.

Allterra’s comprehensive Geologic Hazard Investigation evaluated seismic shaking, ridge top shattering, co-seismic ground cracking, erosion, and land sliding to define safe buildable areas of the parcel where Planning Department will approve construction. We completed file reviews at the Planning Department, field reconnaissance, geologic mapping, exploratory trenching, and interview of County Geologist and Planning professionals to provide recommendations for development of the property.

Our recommendations included:

  • Building Envelope: County approved area safe to build;
  • Waste Disposal System: Design, size, and location of waste disposal system;
  • Parcel topography and drainage; and
  • Setback and mitigation of Geologic Hazards.

Fern Flat Geologic Hazard Investigation resulted in approval by the County to proceed with site construction.
