Effective. Professional. Experienced.

Flows from Strentzel Creek on National Park Service (NPS) land periodically flooded local neighborhoods in the outskirts of Martinez in Contra Costa County. Working with the County and NPS staffs as well as the neighborhood, we designed a new drainageway on NPS land that would safely convey flows as well as store sediments without impacting NPS lands, which include the gravesites of John Muir and family.  We then completed a variety of special status species assessments, wrote the required NEPA and CEQA documents and completed permits through the Corps, RWQCB and CDFW.

The Contra Costa Water District, like many other local Districts, sought to include a solar power facility on unused portions of its lands in the County.  Though the site was small, there were a number of complex issues including the proximity of the project to adjacent residential housing, Lime Ridge open space and potential special status species. Zentner Planning and Ecology wrote the biological portions of a CEQA document, worked with local staff to address these issues, and wrote the responses to the CEQA comments. We then completed follow-up surveys to ensure that all local planning issues were resolved.
