Project Summary

Staff Consultant/GIS Analyst, Safety Elements for the Cities of Glendale, Pasadena, Fontana, Brea, Rancho Santa Margarita, Desert Hot Springs, Palm Desert, and Cathedral City, California. Maintained and Created used in the GIS mapping of Geologic Hazard Maps. Derived landslide and liquefaction susceptibility maps using geologic mapping, slope stability analysis and groundwater data. Used GIS to identify potentially hazardous areas due to landslide, liquefaction, fault rupture, flooding, dam failure Inundation, and wildfire hazard. Used HazUS to analyze earthquake loss estimation due to different earthquake scenarios.

Staff Consultant/GIS Analyst, Fault trenching and tectonic geomorphic study along the Garlock and San Andreas faults. Maintained database of detailed geomorphic and geologic mapping of the Garlock and San Andreas faults within a 25,000-acre area. Used Cone Penetration tests (CPT) and Borehole data to identify potentially active faults in the area.

Staff Consultant/GIS Analyst for Playa Vista Corporation – Groundwater and Methane Migration Investigation on Playa Vista Property, Los Angeles, California. Conducted field exploration of methane within the groundwater and soils. Created a GIS database containing information about subsurface well exploration. Used the GIS database for development of site geologic and hydrogeologic investigations. Used Cone Penetration tests (CPT) and Borehole data to identify potentially active faults in the area.

Staff Consultant/GIS Analyst for Safety Element of the General Plan, Riverside County. Developed the countywide GIS database and produced new hazard maps. Used GIS to identify potentially hazardous areas due to landslide, liquefaction, fault rupture, flooding, dam failure Inundation, and wildfire hazard
