Boise Airport 14 CFR Part 150 Study Update Updated Noise Exposure Maps and Noise Compatibility Program Prepared for: CITY OF BOISE Prepared by: HNTB Corporation CSHQA Wyle Laboratories Synergy Consulting JULY 2004 (EXECUTIVE SUMMARY ADDED SEPTEMBER 2006) Boise Airport - Part 150 Study Update Executive Summary The Federal Aviation Administration (FAA) has approved the updated noise exposure maps and the noise compatibility program (NCP). The NCP is intended to reduce the impact of aircraft noise on people who live and work near Boise Airport. The Airport, owned and operated by the City of Boise, is the busiest air terminal in Idaho, serving 3.0 million passengers a year. In 2004, Boise Airport completed an update to its Part 150 aircraft noise and land use compatibility program. The two central elements of the Part 150 Study Update are: • Noise Exposure Maps, showing existing (2004) and forecast (2009) noise exposure levels due to aircraft operations at Boise Airport. • Noise Compatibility Program, or NCP, which including noise abatement, land use, and continuing program measures to improve aircraft noise and land use compatibility. The study presents current and future land uses in communities around the Airport and assesses the compatibility of that land use with the current and probable future noise levels. The study uses this assessment to formulate a realistic plan of land use and noise abatement measures, as outlined in the NCP, to reduce noise and its impact on people. The Federal Aviation Administration (FAA) accepted the Noise Exposure Maps in August 2005. Then in February 2006, the FAA approved many of the elements of the comprehensive Noise Compatibility Program, which consists of 30 measures that were approved in whole or in part. The NCP includes 7 measures to limit aircraft noise; 18 measures to encourage more appropriate zoning and land use in noisy areas; and 5 measures to provide better community coordination and responses to complaints. The study calculated aircraft noise levels, identified land uses near the Airport, and forecast the changes that are expected in the future. (The study accounts for the temporary decline in aviation activity that followed the 2001 national economic recession as well as the terrorist attacks of September 11, 2001.) A wide variety of noise abatement and land use measures were evaluated to determine which are most likely to provide the greatest benefits to the largest number of people in the future. These measures were recommended to the FAA in the final report. STUDY PROCESS A 14 CFR Part 150 Study, as established in the Code of Federal Regulations, is an effort to improve the overall noise environment near an airport without shifting noise from one residential community to another. In 1996, the City of Boise completed a Part 150 Study, which has been successful in reducing noise impacts for residents. In fact, Boise Airport has among the fewest number of people (about 82 individuals today) affected by significant aircraft noise (> 65 DNL) of any airport of its size in the United States. Throughout the recently completed study, the City consulted with a 20-member Advisory Committee of representatives of the community, government agencies, and other Airport stakeholders. The City also held three public workshops to explain the study process and obtain feedback on study results and proposed noise compatibility measures. Aircraft Operations The average number of operations (take-offs and landings) at Boise Airport is expected to increase about 1.7% from the current level of 458 per day to 498 per day by 2009. The types of ES-1 Boise Airport - Part 150 Study Update Executive Summary aircraft that operate at Boise Airport, known as the fleet mix, are expected to remain relatively stable as shown in the following chart: Boise Airport Fleet Mix for 2004 and 2009 500.0 s 400.0 Regional Prop Regional Jet 300.0 Passenger Jet Military 200.0 General Aviation Prop/Helo General Aviation Jet Cargo Jet Average Daily Operation Daily Average 100.0 0.0 2003 2008 Figures ES-1 and ES-2 show typical flight tracks of aircraft operations at Boise Airport, as well as runway use by the percentage of all operations that flow in a given direction. While flight tracks, which are generated by a statistical average of actual radar flight tracks, cover much of the area surrounding the Airport, the flight tracks are concentrated in arrival and departure corridors that are in line with the runways. The fleet mix, number of operations, runway use, and flight tracks, are entered into the Integrated Noise Model (or INM, which is the FAA’s computer program that calculates noise exposure contours presented in this study). INM accounts for variations in aircraft noise due to different models of aircraft, flight paths, seasonal variations in the weather, terrain, and the cumulative impacts of noise from multiple flight operations over a single geographic area. Noise Exposure Maps Figures ES-3 and ES-4 show the 2004 and 2009 Noise Exposure Maps at Boise Airport, as accepted by FAA. The Noise Exposure Maps show existing areas of aircraft noise, known as “contours” (black lines), overlaid on land uses. Land uses near the Airport include residential (yellow and tan), commercial/industrial (red and gray) and parks and open space (light and dark green). This information was the basis for the technical evaluation of aircraft noise abatement measures to determine the most effective ways to reduce the number of people exposed to noise in residential areas. Because of the relatively small number of people (82) who are currently impacted by significant aircraft noise (> 65 DNL), the study focused on land use measures, such as zoning standards and updates to building code requirements, which will minimize the number of people who could be exposed to aircraft noise in the future. Today there are an estimated 31 homes within the geographic areas, or contours, around Boise Airport where average daily noise levels (DNL) are 65 decibels or greater.
