Alquist-Priolo Fault Investigations for Subdivisions
    Where is it safe for homes?  Where can roads go?
Damage Evaluations (Earthquake, Landslide, Flood)
    What was damaged and how severely?  What caused the damage?  Is future damage likely?  Is their anything I can do?
Disclosure Reports for Real Estate Transactions
    How do you inform potential buyers fully to minimize the risk of litigation due to "failure to disclose?"  How do you show your property in the best light and still disclose all that must be?
Erosion-Control Prescriptions
    When is enough, enough?
Erosion-Rate Studies to Determine Setbacks
    Should I consider global sea level rise in my planning?
"Geological Surveys"
    What is the least amount of work I need done for my permit?
Groundwater Availability Evaluations
    Can you give me information just from geologic maps?
Landslide Mapping for Hazard and Risk Assessments
    Is the neighbor's landslide threatening ME?  Is MY landslide threatening THEM?  Did he cause it; did I? 
Landslide Stabilization Recommendations
    What are the cost-effective options for this site?  Will spending more reduce the long-term risk of another failure?
Litigation and Arbitration Support
    What geologic or geotechnical information does my attorney need?
Oblique Aerial Photography (35 mm)
    Want a photo of your property, home, or commercial building?
Project Feasibility Investigations
    Can I get 10 lots on this parcel?  Where would a road be most stable?
Real Estate Support Services
    Are you buying or selling or just shopping around?
Resource Management Support (e.g., Timberlands)
    How can I maximize my harvest and remain in compliance?
    What is the approximate volume of available rock?  Borrow?
Road Alignment and Stability Evaluations
    Where is the most stable alignment?  What are my cut / fill options?
Reports for Lot Splits and Subdivisions
    Our short-form "checklist" report will get the job done!
Septic Disposal System Evaluation and Design (CA)
    Can I develop / subdivide this property?
    Can I convert from apartments to a duplex?
    Is there any way to construct a cheaper system?
Slope Monitoring with Inclinometers, Tiltmeters, Grids
   Do you need accurate, precise quantitative information?
   Which monitoring method is most appropriate, most affordable?
"Soil Reports" (Residential, Commercial, & Industrial)
   I just want it to be easy!  We can help.
Timber Harvest Plan Geologic Elements
   How can I maximize yield and remain in compliance?
Verbal Assessments for Real Estate Purchase Decisions
   What's the risk from this hill?
    Could the ocean erode back to here?
    Could a tsunami reach this high?
    Is a Cascadia earthquake really likely?
    Is that stream or a high groundwater table a threat?
    Plain and simple, "What's the risk?  Is it safe?  Should I build?"    
"What does this crack mean?"
   Stability analysis of soils and hillslopes.
   Analysis of the cause of settlement or movement of structures.
"Why is this tree leaning?" 
   Is it a sun-loving (heliotropic) or gravity-loving (geotropic) tree?
    Mathematical slope stability analysis via "eyes only" methods.
    Inspection of individual trees and groups.

Drilling to set a slope inclinometer at the head of a large rotataional landslide, South Bank Chetco River Road, Brookings, Oregon. We have been monitoring this home since 1999 and the ground has remained stable, to the relief of the owners.

Aerial view of the Rainbow Rock Condominium Complex just north of Brookings. Site-specfic stability evaluations are essential for development efforts in coastal Curry Co., Oregon, due to highly variable, often structurally incompetent bedrock.

A debris slide along Requa Road, Del Norte County, CA, triggered by a high-rainfall event. This slide closed the road and has progressed upslope over time. It is still growing headward.

This Brookings, OR, home is many inches out of level. The foundation rests on deep topsoil and, additionally, the bedrock is an intrinsically weak, easily erodible mudstone. The white ^ point at two of the most prominent ground breaks on the yard.

This "Park Model" mobile home in the Whaleshead Creek development north of Brookings, OR, is sliding downhill, dramatically tilting, and pulling apart because the contractor who build the pad did not properly prepare the ground to receive fill, nor did he compact the fill adequately.

This deck, now partially undermined by sliding soils, faces the incredibly beautiful mouth of the Smith River. But would you have a martini on it? We answered that question for the owner.

BGC did fault evaluation reports for many of the parcels in this photo before development occurred, and we did the geologic hazards and risks / foundation soils reports for many of the individual subdivisions or lots.  Humboldt Hill, Eureka, California.
