Airport Noise Contours

Updated March 2023 Noise contours in decibels for areas surrounding airports in the Sacramento, Sutter, Yolo, and Yuba counties' Airport Land Use Commission (ALUC), compiled from individual airport files to make a single regional layer. The SACOG Board of Directors serves as the Airport Land Use Commission (ALUC) for Sacramento, Sutter, Yolo and Yuba counties. California’s State Aeronautics Act (Public Utilities Code, Chapter 4, Article 3.5), identifies the role and responsibilities of the ALUCs in land use planning. The Act’s ALUC requirements are intended to ensure that proposed land uses near public-use airports are compatible with airport uses in terms of safety, noise and air space. One of the ALUC’s primary functions is to develop and adopt a plan that identifies zones for safety, noise contours, and height restrictions, along with associated compatible land uses, for each public-use airport. These plans are referred to as Airport Land Use Compatibility Plans (ALUCPs). For more information regarding ALUCPs, visit the ALUC page on the SACOG website. Updates as needed.
