Mr. Maas commented on the materials presented by Mr. Valerio and Ms. Gomez.
...
Mr. Maas reiterated those homes that are in, or touching the area will qualify for either AIP Grants or PFCs without question.Staff is proposing to take the regulation further.He said, this area is unusual from what is normally done with Airport and federal regulations.
Mr. Maas said that if the measured noise contour ever grows 1.5 dB bigger than the projected contour, the process of updating the map occurs.He stated the homes inside the 65 CNEL qualify for Federal grants and PFCs; the area outside of the 65, will not.The Airport will have to work with the FAA to justify the use of PFCs to treat the secondary area.Airport staff feels this is an equitable way to draw the line for treatment areas.
Mr. Maas explained that the 65 dB line on the map implies a level of certainty; however, there is a 1.5 dB tolerance . Staff proposes to get the secondary homes in place and begin looking for funding.
Mr. Maas asked Mr. Valerio to review the geography around the Airport using the 63.5 criteria, stating that this criterion is the best way to have equitable treatment around the Airport and to have a reasonable chance of qualifying areas for treatment outside the 65 decibel area with the FAA.
...
Mr. Maas said with the phase out of Stage 2 aircraft, FAA had taken a look at contour shrinkage nationwide.Although, contours should shrink and reduce acoustical treatment areas, SJC's contour was growing, which resulted in the need to update our NEM..There was a temporary shrinkage in traffic reduction after September 11th, however, based on the nature of business in the Silicon Valley, we expect a growth in traffic to return which is indicated in our presentation.
...
Mr. Maas said the map, as well as public comments and questions would be on the website.The comment period would be extended to February 21, 2002, but would not be able to go beyond that date, as we are trying to meet an Airline Commission date of the first week of March . He also said, staff could provide color copies of the map as needed.
...
Mr. Maas said we are not familiar with the east coast reference but will look into the matter further, as this may be helpful information to support our Airport's 63.5 CNEL proposal.
PUBLIC INPUT ON THE NOISE EXPOSURE MAP UPDATE
The following input was received from the audience:
Noise Exposure Map Issues
...
Mr. Maas said all input would be considered and said the purpose of tonight's meeting was to receive public input so we could move forward with the Noise Exposure Map Update process.
...
Deputy Director Dave Maas went over the "next step" process explaining that Public input will be compiled and taken to the Airport Commission Meeting the first week of March.Staff will recommend City Council approval of the Noise Exposure Map, and send revised treatment area recommendations to the FAA.Mr. Maas noted the FAA, has a six-month process to approve maps.The final step would be to amend our PFC Applications to provide funding for these projects.Staff has submitted a pre-application as a informal document; however, once approval has been given, we would submit a formal grant application.
Chairman Blake adjourned the meeting at 7:55 p.m.
