Description: Nut Tree Airport is a general aviation (GA) airport located in Vacaville CA roughly halfway between San Francisco and Sacramento. The Airport is located on the I-80 corridor and has easy access to both Interstates 80 and 505.The Airport consists of 286 acres and receives approximately 102,700 aircraft operations each year. The Airport is home to 201 based aircraft and has 117 hangars and other various commercial office spaces. The Airport’s 4,700 foot long runway can accommodate a variety of aircraft from single engine to twins to small/medium sized business jets.Nut Tree Airport Master Plan Noise Contours:The 1988 Airport/Land Use Compatibility Plan (ALUCP) includes supporting policies related to aircraft noise. The California Code of Regulations, Title 21, Subchapter 6 indicates that the State of California prohibits four land use types to be located within the 65 decibel (dB) Community Noise Equivalent Level (CNEL) exposure level, which include public and private schools, places of public worship, residential dwellings, and hospitals. In order to enforce these noise regulations, each airport is required to develop a noise exposure map delineating the 65 dB CNEL noise contour location. Noise policies described in the 1988 ALUCP indicates that the maximum CNEL which shall be considered normally acceptable for residential areas in the vicinity of Nut Tree Airport is 60 rather than 6511. Also, the 2007 City of Vacaville General Plan and the Vacaville Municipal code have also adopted the 60 dB CNEL noise level as the residential compatibility threshold. The noise contours illustrated in the 2007 General Plan are based upon the 1993 Nut Tree Airport Master Plan 2011 future noise contours. These contours were anticipated to be incorporated into the 1988 ALUCP; however, the 2007 General Plan indicates that the 1988 ALUCP has not been amended to incorporate the 1993 Nut Tree Airport Master Plan noise contours. As stated above, the State of California restricts the four incompatible land uses within the 65 CNEL exposure level. Further analysis and potential recommendations for changes to adopted noise contours will be included in later chapters of the Master Plan. The 2011 55, 60, and 65 CNEL noise contours based upon the 1993 Master Plan are presented in the mapping data. It is important to note that these 2011 noise contours are based on a forecast included in the 1993 Airport Master Plan of 180,000 annual aircraft operations. Actual 2009 aircraft operations were estimated to be 101,500.
