This question was not addressed in the 1998 HVSP FEIR. The nearest public airport to the project site is the Livermore Municipal Airport, located approximately 4.5 miles northeast of the project site. Because of the distance from and orientation of the airport runways, the project site is located well outside of the 65 dBA Community Noise Equivalent Level (CNEL) airport noise contours. Therefore, implementation of the proposed project would not expose persons residing or working in the project site to noise levels from airport activity that would be in excess of normally acceptable standards for residential land use development. In addition, there are no private airstrips within 2 miles of the project site. Therefore, no impact would occur and no change to the 1998 HVSP FEIR conclusions regarding noise is required. FEIR Mitigation Measures Construction noise impacts would be reduced to less than significant with implementation of MM C4 of the 1998 HVSP FEIR. MM C4 Construction activity is limited to the hours of 8:00 a.m. to 5:00 p.m., Monday through Saturday. Conclusion No new significant impacts to noise and vibration would occur. The conclusions from the 1998 HVSP FEIR remain unchanged.
