Ms. Watson’s extensive experience in government allows her to assist clients in a wide range of environmental practice areas, including air, water, waste, site remediation, wetlands, stormwater, and underground storage tanks. Her practice areas include compliance, permitting, remediation, enforcement defense and litigation. Her previous experience as a commercial real estate attorney also makes her uniquely able to assist clients with the environmental aspects of property transactions.
