June 1 is the deadline for public comment on an environmental document pertaining to a plan to integrate a 483-acre tract in Franklin Canyon with the adjacent 702-acre Fernandez Ranch property.

The plan would open the tract for public use and reintroduce grazing to improve rangeland health.

An initial study and proposed mitigated negative declaration finds that the proposed project will not have a significant effect upon the environment by virtue of revisions by its proponent, Muir Heritage Land Trust.

The Franklin Canyon property once was envisioned for development of more than 500 homes, offices, stores and a hotel. But a citizens-sponsored initiative approved by Hercules voters in November 2004 restricts land use there mostly to recreation and agriculture.

The initial study is available for review at Hercules City Hall and also is available on the city website via a link in Monday's Planning Commission agenda. The direct link to the agenda is www.ci.hercules.ca.us/documents/Agendas/Planning/2013/05-06-13/Agenda.pdf.

The public comment period began Wednesday. Written comments should be sent by mail to City of Hercules Planning Department, 111 Civic Drive, Hercules, CA 94547, Attn: Robert Reber, or by email to rreber@ci.hercules.ca.us. The Hercules Planning Commission expects to hold a hearing on the matter June 17 to consider a conditional use permit for the project.
