." 0 0.0% Yes, because "At locations outside DNL 65, community noise is equal or greater to the aircraft noise." 0 0.0% Yes, because "FAA has a national policy of not addressing noise from aircraft weighting less than 12,500 Online flight tracking." 0 0.0% Yes, because "The lack of evidence/precedent indicating sound insulation of ‘floating' homes would be effective." 0 0.0% 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.

Comment Responses: Flight school pilots change so frequently that it is hard to keep everyone current on noise abatement procedures. They could be very effective with FAA support Very effective weather permitting When adhered to by ATC and jet pilots Late night, turns over water, minimum shoreline crossing altitudes are very effective in reducing noise.

Operation directives to enforce run-up policy Airport Rules and Regulations set forth operational procedures governing GRE use, enforcement, and five levels of incentive or penalties for compliance.

91 Comment Responses: None Not all realtors or homeowners are cooperative even though they can be sued for non-compliance. No drawbacks Voluntary compliance -- No oversight Developers seeking P&D rezoning in our airport district zones for in-fill development Recommendations not always heeded Sometimes the local officials do not contact the airport on critical land development.

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.

From page 92... ...
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.
