Kathryn L. Oehlschlager

Partner

With more than fifteen years of experience in environmental law, Kathryn Oehlschlager has built a robust practice spanning environmental and land use compliance counseling, state and federal enforcement defense, and major litigation.

Public and private clients turn to Kathryn for advice on compliance with all facets of environmental and land use law, including CEQA, NEPA, federal and state endangered species laws, contaminated site remediation, water quality and supply issues, and laws regulating solid and hazardous waste. She routinely represents clients in all aspects of the CEQA project review process, including preparation, review, and analysis of negative declarations, draft environmental impact reports, and final environmental impact reports. Kathryn also has substantial experience managing contaminated sites, from investigation and remediation through the entitlement process and redevelopment.

Kathryn also has a proven track record with high-stakes litigation, having handled numerous land use and environmental cases in state and federal trial courts and through the courts of appeal. Kathryn is equally comfortable handling writs of mandamus and traditional civil litigation matters, and regularly represents clients in administrative appeals, including the second appeal ever heard by the Delta Stewardship Council.

As a compliance counselor, Kathryn’s goal is to help her clients minimize downstream risk and avoid litigation and enforcement. As a litigator, Kathryn’s goal is to achieve the best results for her clients, deftly navigating administrative proceedings, negotiations with regulators and opposing parties, and high-stakes trials.
