Vanessa Davis

Staff Geologist

Vanessa Davis, PG, has over 2-years’ experience as a Junior Geologist for LACO Associates. Prior to working for LACO, Ms. Davis received education experience particular to that which would be useful and necessary at LACO. On top of receiving a Bachelor’s Degree in Geology, Ms. Davis spent four weeks at a Geology Field Camp in Ely, Nevada where she focused on geologic mapping, geologic structures and geomorphology, and interpreting geologic history with a minor emphasis on rock and fossil identification. In that same experience, she created geologic maps, cross sections, as well as topographic and aerial photography interpretations.

Ms. Davis performed soils logging and drafted geotechnical reports. 

Water Resource Permitting – Multiple Locations, California.

For Hydrology and Geomorphology projects, Ms. Davis located potential sources of sediment, identified sections of road in need of improvement, and determined whether culverts were properly sized. Ms. Davis performed geologic mapping of properties to include all roads, stream crossings, watercourses, and existing structures using iPad technology. She also generated GIS maps of those sites using KMZ files. 

Phase 1 Environmental Site Assessments – Multiple Locations, California.

Ms. Davis conducted site visits to determine possible environmental hazards. She would then draft reports which presented such findings.
