Christopher A. Walker advises and represents a diverse range of clients on matters of environmental law.  His current and former clients include large and small businesses, local governments, land banks, conservation organizations, farmers, and individuals. A former Ohio Assistant Attorney General, Chris has worked with virtually every facet of federal and Ohio environmental law in a career that spans over thirty years.

Chris provides guidance to clients and law firms on issues of environmental compliance and liability avoidance in a wide variety of contexts, including business and real estate transactions, environmental cleanups, negotiation of administrative orders, estate planning, and probate. Chris also advises and represents landowners, local governments, and community organizations in environment-related land use matters, including brownfield redevelopment, federal facilities cleanups and environmental impact statements. He represented a city and its community improvement corporation in the $1 billion cleanup of a former U.S. Department of Energy facility, and has advised parties in the sale or donation of conservation easements resulting in the permanent protection of over 1,800 acres of farmland and open space in western and central Ohio.

From 1995-99, he was a member of the environmental practice group of Thompson, Hine & Flory, a major Midwest law firm.

Chris also serves as a mediator and facilitator in connection with environmental and public policy matters.
