42 APPENDIX B Survey Results and Analysis SUMMARY This report contains a detailed statistical analysis of the results to the survey titled Survey for Airport Noise Officers on Noise Issues Outside DNL 65. The results analysis includes answers from all respondents who took the survey in the 95 day period from Monday, April 28, 2008, to Thursday, July 31, 2008.

45 Comment Responses: All noise concerns are treated with equal importance no matter where they are located. With no population inside the 2005 65 DNL contour, all noise concerns are outside DNL 65. Interagency Agreement with four airports. We have experienced significant reduction in incompatible land uses around the airport since the mid-1980s. Using 60 DNL for some land use planning since early 1990s. Some communities are affected with noise outside the DNL 65 when departure patterns are altered during runway closures for construction. We accept the FAA's DNL 65 standard. It is our experience that the levels of annoyance over aircraft noise at our airport are minimal based on the complaints received.

51 11) Has FAA denied your airport's plans to mitigate or abate noise outside DNL 65? Response Count Percent Yes, because "Noise below DNL 65 is not significant." 2 6.3% Yes, because "FAA does not fund actions outside DNL 65" (or it is such a low 10 31.3% priority that it will never be funded). Yes, because "The sponsor has not shown that there is a problem outside DNL 65." 1 3.1% Yes, because "The local community has not enacted the local land use policies 0 0.0% (including provision to protect areas outside DNL 65)." Yes, because "At locations outside DNL 65, community noise is equal or greater to 0 0.0% the aircraft noise." Yes, because "FAA has a national policy of not addressing noise from aircraft 0 0.0% weighting less than 12,500 Online flight tracking." Yes, because "The lack of evidence/precedent indicating sound insulation of 0 0.0% `floating' homes would be effective." No 9 28.1% Other 10 31.3% Other Responses: No Part 150 program at this airport for FAA to approve or deny No Part 150 study conducted Decision on this airport in August Never presented to the FAA in any airport documents Part 150 pending action by FAA. The airport is in the process of conducting a Part 161 study. Unfair question Not applicable Does not apply No. This airport has only requested FAA to fund sound insulation to end-of-the-block, which does extend outside the 65 dB CNEL. They have agreed to use of general airport revenues for mitigation due to settlement of litigation proposed procedure opposed by local ATCT Comment Responses: Only FAA involvement is noise abatement flight track. We have not asked and do not intend to This airport does not have plans to support any mitigation outside DNL 65 We don't formally pursue because it will be denied. Everything we are doing is not in conflict with our FAA covenants or FAA regulations.

52 The DNL 65 is located within the airport boundary. We did not ask the FAA to fund mitigation, but were denied approach and departure procedures outside the DNL 65. This question should allow for multiple answers. Can you tell me why the burden should be placed on airports to mitigate outside the DNL 65 levels when local communities are not willing to mitigate along roads and railroads with equal or even higher levels. The policy is wrong for airports. Airport is conducting a Part 161 study to try to restrict aircraft from departing to the east over residences between midnight and 6:30 a.m., which disturbs areas outside current 65 dB CNEL. 12) Do you use noise abatement flight tracks for noise abatement?

92 58) Do you have any information that you believe would be helpful to this study? If so, please indicate below. I'd be happy to provide additional information. I am not sure what is meant by a "case study" but the Port has worked on many projects to address noise outside the 65 DNL contours including pursuing RNAV, building a GRE (due to state requirements) and establishing helicopter training patterns at HIO. On file with HMMH. All components of our program are based on issues outside the 65 CNEL. This facility was among the very first U.S. airports to implement ANCLUCAirport Noise Control and Land Use Compatibility in 1979 and have completed 2 FAR Part 150 Study Updates. The airport has a fully cooperative relationship with the local jurisdictions for land use in the 65 DNL. Outside of the 65 DNL, the local jurisdictions do not prohibit noise sensitive land uses. The airport must impose noise disclosure on its own and must convince school district to sound insulate new schools outside of but close to 65 DNL. With a population exceeding 20,000 and over 10,000 dwelling units inside the SDIA CNEL 65, we estimate it will take 30+ years to mitigate through residential insulation. Before FAA authorizes money to be spent to mitigate aircraft noise issues beyond CNEL 65, perhaps someone should consider whether we need to re-evaluate first generation sound insulated homes and decide whether money is better spent on those closest to the source and most susceptible to injury. Some sort of participation by the FAA would be helpful outside the 65. In general, we believe the industry is opposed to mitigation beyond the 65 db DNL. Mitigating beyond the 65 db DNL would significantly increase the numbers of homes eligible for sound insulation. Consequently, this will increase the financial burden on the FAA and airport operators (local share of grants). The majority of airports (medium and small hub) do not have adequate funding or resources to complete existing noise programs within the 65 db DNL contour. Airports that successfully completed 65 db DNL mitigation programs will be required to initiate new noise programs and this would take away the limited federal funding from those airports not yet finished with their existing 65 db DNL mitigation programs. Background and other noise sources (roadways) can greatly influence noise levels in a neighborhood. Beyond the 65 db DNL, it is not a given that aircraft generated noise will remain the prime noise issue. This community has a unique program in the U.S. Full-time Airport Noise Coordinator although the city doesn't own/operate an airport. Airports are seriously handicapped in dealing with ATCT staff if their noise abatement programs are not formal. They have told us (Authority) that they can do anything they want at this facility because we have an informal program. The airport and the local jurisdictions use policy contours not acoustic contours, adopted by ordinance, to govern land use. Areas in acoustic 6065 within policy 65. Also facility has 18,500 acres. 65 DNL nearly on airport property. Local cities regulate areas beyond airport based on policy contours. Just Part 150 info on the number of homes/residents in the 60 to 65 DNL area and recommendations that were not adopted by the FAA in 2001. Currently undergoing Noise Study. Most issues outside of 65. Use of alternative metrics; community extensive role. Very difficult on consensus due to shifting of noise. A lot of our noise complaints occur during flight changes due to runway closures. Also, aircraft approaching the runways will follow ILS procedures until they get visual contact of the runway and

93 drop their elevation by 2000 feet over the community. We are working with the ATCT to try to eliminate this procedure. Currently we have no formal program for addressing noise outside of the 65 DNL. We are trying to keep the lines of communications open. We do offer the following on a limited basis: 1) Open the Noise Model Home to general public for noise mitigation ideas. 2) Will be putting together a "Tips on" flyer handout for hiring contractors and home mitigation. 3) The local municipality is considering a community-wide property reassessment. We are in current discussions for the potential for "Grandfathering" homes in the 6064 DNL from being reassessed or freeze them at the current value for 1020 years. That commitment may or may not be approved. Airport uses pre-ANCA noise contours; Actual 65 on airport property, which would invite residences at fence; local jurisdictions adopted policy contours and understand benefits to continued use until pressure from developers caused the cities to request new noise contours; updated contours in process now. The expert studies that were developed and presented in court as part of the litigation related to mitigation beyond the 65 DNL contour at MSP.
