Experience

Legal Work Highlights

Represented a developer of an eight-story condominium project in a “brownfield” area in a CEQA petition—getting a dismissal via a motion challenging a writ’s substantive claims, targeted aggressive response resolved in a court dismissal a month into the lawsuit.

Defended a metal parts stamping company in a state lawsuit brought by neighboring business alleging PCE/TCE contamination from our site to theirs. Argued the neighboring site was an enormous source of PCE/TCE contamination before the State Regional Water Quality Board—turning its attention to the neighboring business. Opposing counsel then agreed to toll the state lawsuit.

Represented a public entity seeking to expand their wastewater treatment facility by defeating a challenge brought on by an environmental group alleging that the wastewater treatment facility should heat its reclaimed water discharges into an adjacent stream to protect a protected local fish species’ spawning area. The environmental group alleged that the reduced loss of this fish species was because of chilled wastewater releases impacting spawning eggs. Thierry used legal and scientific evidence tying species loss to heron and small mouth bass predation and not his client’s wastewater discharges.
