Expertise Description

I have over 25 years experience as a hydrogeologist and geologist. My expertise includes: civil engineering; coastal erosion; engineering geology; environmental engineering standards-of-care; flood hydrology; groundwater / surface water assessment / development / litigation, management / protection; hydrocollapses; landslide evaluation (groundwater / seepage source determinations); seismic risk evaluation; sewer-line failure and resulting groundwater contamination; water pipelines; water resources development / remediation; water rights; watersheds / runoff issues; and wells (wellfields, wellheads). I have prior expert witness experience with consultations, deposition, and courtroom testimony.

Areas of Expertise

Expert Witness

My expert witness experience includes watershed and runoff contribution study.

Consulting Experience

My consulting services include management of technical operations & business development for all water resources development & remediation, seismic risk evaluation, and engineering geologic services, as well as applied environmental services. My numerous hydrogeologic projects include large residential development; seepage and groundwater source investigation; hydrologic investigation for hydrocollapse of fill slopes; natural spring water supply feasibility; basin evaluations.

Relevant Experiences

My professional and litigation support experience span both hydrology and geology expertise.  

I have served as an expert witness several times concerning slope erosion, hydrology and debris-flow matters. I provided trial testimony and field investigations as a primary defense expert for the State of California concerning a large, fatal forest fire. I have served as expert, including trial testimony, on multiple cases involving storm runoff, slope erosion and debris flow damages. My colleagues and I have provided debris-flow hazard assessment and engineering mitigation services to the US Forest Service in several wildfire-impacted areas within California and Arizona.
