I represent clients with a range of legal issues associated with project development, particularly projects that involve purchasing, selling, or redeveloping contaminated sites.  My goal is to cost-effectively help clients navigate the legal hurdles necessary to reach their business objectives and effectively manage legal and financial risk along the way.

Polly Jessen’s practice focuses on the range of contaminated property redevelopment issues, including environmental due diligence, negotiating purchase and sale agreements, cleanup plans, development agreements and environmental insurance policies, obtaining Brownfield grants and state tax credits, severed mineral interests, mine reclamation, and professional service and construction contracting. Polly advises and represents clients before regulatory agencies regarding remedy selection, administrative orders, cleanup standards, institutional controls, redevelopment, and community relations activities under voluntary cleanup agreements and regulatory orders. She has drafted ordinances governing solid waste management and development standards for areas of statewide interest. Polly also has drafted comments to regulatory agencies regarding wetlands permits and endangered species issues, prepared briefs and other pleadings in environmental and natural resource litigation and mediation proceedings and served as an expert witness with respect to Brownfields transaction structures and “all appropriate inquiry.”

Polly’s clients include municipalities and quasi-governmental entities, as well as private developers, lenders, and other private entities involved in complex remediation and redevelopment projects.
