Transcript

  • 1. BOCA RATON AIRPORT FAR Part 150 Noise Exposure Map Update AAAE Airport Noise Mitigation Symposium | October 2009
  • 2. The NEM Update Team
    • Ricondo & Associates Miami, Florida
    • Barnard Dunkelberg & Company Tulsa, Oklahoma and Denver, Colorado
    • Mestre Greve Associates Laguna Niguel, California
  • 3. Agenda
    • Purpose of Study
    • Brief Explanation of the Noise Exposure Map Update
    • Why do an Update?
    • What has changed since previous Maps?
    • Inventory/Forecast
    • Draft Existing and Future Noise Exposure Maps
    • Draft Land Use Analysis
    • Shrinking Contours
  • 4. Purpose of Study
    • Voluntary noise exposure map preparation to continue to receive FAA funds for sound attenuation.
    • FAA requested an update of the 2001 NEMs due to changing conditions at Boca Raton Airport.
    • Study to Identify:
      • Existing noise exposure (2008).
      • Potential future noise exposure (2018).
      • Number of people that would be exposed to significant aircraft noise levels (65 DNL or greater).
      • Determine eligibility boundaries for potential future noise insulation.
  • 5. Purpose of Study (continued)
    • Study has a 10-year planning horizon
      • Existing 2008
      • Future 2018
    • The Noise Exposure Maps (NEMs) are submitted to the Federal Aviation Administration.
  • 6. Study Process, October 2009 1 INVENTORY OF EXISTING CONDITIONS DEVELOP AVIATION ACTIVITY FORECASTS GENERATE EXISTING NOISE CONTOURS GENERATE FUTURE NOISE CONTOURS NOISE/POPULATION ANALYSIS DEVELOP PRELIMINARY ELIGIBILITY BOUNDARY PUBLIC HEARING ADOPTION OF NOISE EXPOSURE MAPS AND SUBMITAL OF PROGRAM TO THE FEDERAL AVIATION ADMINISTRATION FAA ACCEPTS NOISE EXPOSURE MAPS DEVELOP NOISE EXPOSURE MAPS 2 3 4 5 6 7 8 9 10 ACCOMPLISHED TO BE ACCOMPLISHED
  • 7. Why Update Maps?
    • Changing conditions
    • FAA Cannot Grant Public Funds for Projects That Do Not Meet National Criteria – 65 DNL Contour
    • Age of Existing NEM Contours Requires Updating
      • Future Contour Year (2006) Has Passed
    • Before Granting Additional Funds for Sound Attenuation, NEM Contours Must be Verified and Certified
  • 8. What Has Changed?
    • New Version of Integrated Noise Model (INM)
      • Version produces more accurate prediction of aircraft noise contours
    • Actual Permanent Noise Monitoring System and Radar Tracking Data
    • Greater Accuracy Determining Aircraft Types, Flight Tracks, Runway Utilization and Time of Day
      • No longer as many “Guesstimates” concerning input data for INM
      • Example: Time of Day – 2001 Study predicted 23% nighttime ops versus 5% nighttime ops based on 2008 ops data
    • Gradual Conversion of Fleet Mix
      • Stage 2 aircraft transitioning out of fleet
    • Voluntary Noise Abatement Plan is Working
  • 9. 2007 and 2006 Aircraft Operations Comparison to Current FAR Part 150 Forecast Level Source: FAA Air Traffic Activity Systems (ATADS) CY 2006 Total Annual Operations: 91,026 CY 2007 Total Annual Operations: 94,687 Approved 2001 FAR Part 150 Forecast Level of Aircraft Operations for 2006: 173,124
  • 10. Forecasts of Aviation Activity
    • 2001 NEM Update Forecast Operations for 2006: 173,124
    • 2006 contour shows greater operations than the new 2018 forecast
    Year 2008 2012 2018 Piston/Turboprop 54,306 45,696 58,690 Turbojet 36,622 55,089 71,879 Rotor 880 948 1,044 Total 91,808 110,722 131,613
  • 11. Draft Boca Raton 2008 & 2018 65 DNL Noise Contours
  • 12. Sound Insulation Programs at GA Airports
    • Few sound insulation programs at GA Airports across U.S.
      • Boca Raton Airport
      • Oakland County International Airport
      • Considering as an alternative at Chicago Executive Airport
      • Considering as an alternative at Willow Run Airport
      • Boeing Field: Mostly GA Airport with commercial aircraft for Boeing
    • Reasoning:
      • Limited staff
      • Limited funding
      • Lack of awareness/desirability to start
  • 13. Land Use/Population Sources:  Aerial Photography, Land Use Base Map.                 2000 Census Data, BDC Analysis.  The total figures for each contour are cumulative. The contours contain the area within all smaller contours.  Total population and housing units are generally rounded to the nearest five. 5 units per building were estimated for the Vistazo Townhome complex. --- Insulated homes are only shown for the 65 DNL contour since only homes within the 65 DNL contour are eligible for Federal funding. Land Use 65 DNL 70 DNL 75 DNL People 130 0 0 Residential Units 55 0 0 Insulated Units (Including Phase 2) 55 --- --- Insulated – Single Family Units 8 --- --- Insulated – Single Family Units (Phase 1) 2 --- --- Future Insulated – Single Family Units (Phase 2) 6 --- --- Insulated – Multi-Family Units 45 --- --- Un-insulated/Un-attenuated Units 0 --- --- Schools 1 0 0 Total Acres 606 Acres 275 Acres 139 Acres
  • 14. Previous Study Contour Compared to Draft NEM Update Contours
  • 15. The Shrinking Contour Phenomenon
    • Seeing shrinking contours at many different airports:
      • Boca Raton Airport
      • Detroit Metropolitan Wayne County Airport
      • Willow Run Airport
      • Chicago Executive Airport
      • General Mitchell International Airport
    • Contours shrinking due to:
      • Changes in fleet mix, more accurate tracking, decreases in operations, change in INM, etc.
    • Makes public involvement process vital to success
  • 16. Additional Information
    • Kate Andrus, Barnard Dunkelberg and Company
      • 1743 Wazee Street, Suite 400
