Describes the anticipated environmental impacts from the County of Sonoma's proposed implementation of its Runway Safety Area Program for Charles M. Schulz-Sonoma County Airport and other near term improvements Such development includes: extending Runway 14/32 881 feet to the north to a total length of 6,000 feet and extending runway 1/19 198 feet to the north for a total length of 5,202 feet to separate the currently co-located runway ends to provide for a Runway Safety Area that meets Federal Aviation Administration Airport Design Standards. The proposed project also includes acquisition of three parcels of land for construction of the Runway Safety Area and approach protection, realignment of an approximate 700-foot long segment of Airport Creek and installation of an approximate 650-foot long culvert for another portion of Airport Creek, installation of drainage structures, paving, marking and lighting of replacement parallel and connector taxiways, relocation of navigational aids, and relocation of an on-airport Vehicle Service Road. The proposed project will enhance the safety of the airfield consistent with the requirements of the Transportation, Treasury, Housing And Urban Development, The Judiciary, The District Of Columbia, And Independent Agencies Appropriations Act, 2006 (Public Law 109-115) at Charles M. Schulz -- Sonoma County Airport. The proposed action is likely to adversely affect the following federally listed species: Burke's goldfield, California tiger salamander, Sonoma County Distinct Population Segment, and their designated critical habitat. Potential impacts and proposed mitigation measures to federally listed species and their designated critical habitat; historic properties; and wetlands and associated waters of the U.S. are described in the Draft Environmental Assessment. The proposed action is also within a 100-year floodplain for Airport Creek, pursuant FAA Order 1050.1E, Environmental Impacts: Policies and Procedures notice is given that the proposed action constitutes an encroachment into the 100-year floodplain for Airport Creek. The potential impacts of the encroachment are described in the Draft Environmental Assessment.
