GZA works actively with state and federal regulatory agencies and legislative bodies to promote the revitalization of these properties. This has included assisting in the development of recent laws and regulations intended to make the development of so-called "brownfield" sites feasible. Our understanding of the environmental risks and geotechnical engineering challenges associated with these former commercial and industrial sites, as well as the resultant financial impacts, allows us to assist the development of projects in a way that both meets regulatory standards and limits the liability of owners and operators.
