Complex Urban Redevelopment: Extensive experience working on some of the most complex urban development projects in the United States. These projects include a mix of acquisition, environmental, entitlement, and litigation issues. One primary example of this type of representation was the Sacramento Railyards. Jeff served as counsel on deal structure, political strategy, entitlements, environmental remediation, and CEQA issues. The project, which covered over 61 city blocks, was successfully entitled and has received over $300 million in public-private partnership financing to date.

Large Scale Mining Projects: Experienced working in over 30 jurisdictions across California and the western United States working on mining law issues associated with construction materials and metallic mines on private, state, and federal land. Representation includes acquisition, permitting, and litigation counsel for both landowners and mining companies.

Environmental Remediation and Recovery: Experienced with advising clients on complex issues involving environmental remediation issues, including Phase 1 and 2 studies, developing work plans, and recovering under applicable insurance policies and programs.

Energy Projects: Experienced advising clients on the full scope of energy projects, including solar, ethanol, nuclear, and co-generation facilities. This work includes shaping the business transaction, entitlements, negotiating and drafting the Power Purchase Agreement, and handling related litigation, if any.
