Several Noise Studies have been conducted at the Boca Raton Airport. These have primarily been official Federal Aviation Administration (FAA) Part 150 Noise Studies, which include Noise Exposure Maps (NEMís) and Noise Compatibility Programs (NCPís). Both the maps and programs were based on all the Airport data available at the time of the study, and included the collection of specific data for periods of time to estimate the yearly operations and types of aircraft operating at the Airport.
The NEMís are maps of the average Day Night Level (DNL) noise levels, measured in decibels (dB), in the area surrounding the Airport for the design year and a forecast future year. The forecast future year is often a five to ten year estimate of growth at the airport to determine the potential future contours for planning purposes. This future contour is also used to see how various noise programs affect the NEMís.
The NCPís are recommendations that the Studies have produced and are submitted by the study committee and the Airport Sponsor to the FAA for review. These measures have included various voluntary and non-voluntary operational recommendations at the Airport. The FAA then reviews and determines approval or disapproval for the NCP measures recommended in a Record of Decision.
Copies of the Records of Decision for the studies conducted in 1988 to 1990 and 1999 to 2001 are included below. A summary of each proposed NCP measure is listed with the FAA decision and explanations.
