1. Aircraft Noise Exposure Contour Update

2. Overview FAA recommends updating every 5-7 years.
Last official noise exposure map is from 2001.
Worked with Ricondo and Associates to complete the Noise Exposure Map.
Noise exposure contours for day-night average (DNL) sound levels 55, 60, 65, 70, and 75.
FAA does not recognize noise impacts for the purposes of Part 150 beyond the 65 DNL contour.

3. Data Collection Date Range: July 2016 – June 2017 Data Sources
BCT Airport Noise Monitoring System (ANOMS)
Airport Traffic Control Tower (ATCT) Operations Log
FAA Air Traffic Activity Data System (ATADS)
FAA Traffic Flow Management System Counts (TFMSC)
FAA Aircraft Registry Database
FAA's Aviation Environmental Design Tool (AEDT) was used to produce noise exposure contours.

11. Comparative Noise Footprints for Common Aircraft Types in 2001 and 2016-2017

12. Summary Noise exposure has decreased by about 10dB This is caused by:
Fewer overall operations.
Significantly fewer night flights.
Quieter aircraft.
