 HMMH prepared the 2019 noise exposure contours using FAA approved data.

 The contours have slightly shrunk due to small changes in runway use, reductions in departures at night and increase use of quieter aircraft. This is a decrease of approximately 20 percent compared to 2018 (14,713 people DNL 65 dB or greater).

 In 2019, the estimated number of people exposed to DNL (Day-Night Average Sound Levels) exceeding the federal guideline of DNL 65 dB decreased by approximately 20% compared to 2018 (14,713 people in 2018 and 11,792 people in 2019)

 The total area within the DNL 65 dB decreased from 4.30 square miles in 2018 to 3.95 square miles in 2019. OPEN DISCUSSION AND QUESTIONS Adjourn
