After the public comment period for the DEIR closed, the County of Sonoma responded to comments and prepared the Final EIR (FEIR), that includes all written comments received regarding the project’s environmental impacts. The Response to Comments was prepared as a separate document from the DEIR. The FEIR consists of the DEIR and the Response to Comments document and any revisions made as a result of public comments. It was presented to the Planning Commission where they voted to recommendation the project to the Board of Supervisors (BOS). The FEIR was presented to the BOS on January 10, 2012, where a public hearing was conducted and straw votes taken.
On January 24, 2012, the County of Sonoma Board of Supervisors took final action and approved certification of the Environmental Impart Report (EIR) and approved the Charles M. Schulz - Sonoma County Airport Master Plan and related General Plan and Zoning amendments.
