To document National Environmental Policy Act <br />(NEPA) clearance, the Federal Highway Administration (FHWA) has determined that <br />this project will not have any significant impact and prepared a Finding of No <br />Significant Impact (FONSI) in 2005 documenting that this project will not have any <br />significant on the human environment. The preferred alternative (in Exhibit B) was <br />concurred and approved by Caltrans in 2006.
