Airport Noise Contours

This layer defines the areas surrounding Los Angeles County airports that are subject to a range of decibel levels in a 24-hour weighted average noise level known as Community Noise Equivalent Level (CNEL). Please click here to see the Los Angeles County Airport Land Use Planning portion of our website for maps and documents. Some of the airports, such as LAX, and Burbank, have periodic updates of their noise contours. You can also review the following document from the State of California for further information about Airport Land Use Planning. All airport layers can be seen and interacted with together in our A-NET GIS web mapping application - click here. UPDATE: 7/30/2026 - Updated noise contours for LAX Airport (1st Quarter 2026) NEED MORE FUNCTIONALITY?
