Vince Mestre then presented the report to the aviation committee and those of us in attendance. I followed up his presentation with a letter of questions and formally asked the Aviation Committee (in writto forward my letter. Ken Delino refused to forward my letter. He assured me that Vince Mestre would attend the July 28, 1988 Aviation Committee meeting where we could ask him the questions contained. in the letter verbally. Vince Mestre was not in attendance at the July 28, 1988 meeting I asked Ken repeatedly -at the July 28 meeting if he would now forward the letter. He did not respond but Clarence Turner, acting as Chairman in Donald Strauss' absence, agreed the letter would be forwarded. This was agreed in front of a council ghamber packed with Balboa residents. My letter was not forwarded. Ken Delino instead answered for Mestre Greve associates, in writing, a month later. - This resistance to getting questions answered accurately by experts is typical of the way we have been treated by the Aviation Committee. In our requests for consideration our homes have been called "pieces of real estate" and the take off pattern "your problem". The airport and its attending problems is a city wide problem. Therefore, I address this letter directly to the City Council to not only forward my letter to Mestre Greve Associates for their response but also to arrange a meeting with them where concerned citizens might get unbiased, professional answers to their noise questions. I loot: forward to your immediate action on this request. Please circulate this to City Council Member-s. Thank you.

Upon studying the repo 1 only shows two days. = May 11 end� at 4: p31.m. and May 12 ends at 2:07p.m. Do you have any full day's data you could send us as well as the additional missing days that week? We are not intimidated by computer printouts as long as we have some guidelines for interpreting them. - Also, the question of the difference in sound level at the Do`'er Shores area as opposed to -the level experienced on Balboa island has been a subject of debAte betweenWhe upper and lower bay residents. That is why you were asked specifically about it by by both Pete Drummond and myself. Could you please restate what you told me after the meeting as to the maximum and minimum difference and the average dB difference SO I quote you properly when discussing the subject.,, In your presentation you also talked about a dB level difference of 3 or less being barely or not perceptible by the human ear Is that correct? ^ nest~e1.�s / �. Mary & Bill Singleton 315 Sapphire Avenue Balboa Island, CA 92662 June 23, 1988 Chairman Strauss Aviation Committee City of Newport. Beach 3300 Newport Boulevard Newport Beach, CA 92663 Dear Chairman Strauss and members of the Newport Beach Aviation Committee, We appreciate thTe hiring of Mestre Greve Associates to study the noise problem on Balboa Island. Enclosed is a letter addressed to Vince Mestre for you to forward on to him. We would like to suggest that the city extend the Mestre Greve contract to include a study to calibrate the noise monitors in both the upper and lower bays for accuracy. With the results and proper pattern deviation information, they could run a computer footprint based on the average de—c4bel reading for the JWA take- off pattern down the bay. A footprint.based on average decibel increments of three would be logical, since three decibels (according to Vince Mestre) is hardly perceptible by the human ear. ! As you know, we have been working for a year now to get a more equitable and logical take -off pattern from JWA. The only way we, your committee, or the City Council can be assured of a logical and equitable take -off pattern is to have reliable and unbiased information such as a report and footprint by Mestre Greve Associates. We urge you to extend their contract for this purpose.

First, Musire Krevu Associate:; was commissioned .ju produce a 95 SEL contour for Chu MD 80. This was placud on -I map showing the 90 SEL contour for an MD 80 derived from EIR 508. A copy of these contours on a map of Newport Beach, also showing the locations of Moni.Loring Stations #1, #2, 113, and #8 is attached. ALso atLachvd is the most. recent SEL data at all monitoring stations, both in the upper and lower hay. By comparing the data from Monitoring Station #8 to the daLn from MonitorQ', Stations 111, #2 and 113, it is very easv to relate Chu noise on Balboa Island jr to the noise in the Upper Bay.

How can there be "no "aaditionalydatan, as per "your letter of August 26, 1988) when the report gen'1`y ;shows two 'days 'data, May 11 ending at 4:31pm and May 12 ending at y2 07pm,� a, The` three month period SENL July September 1987 is a year old and not what requested. It does, however, 'show Balboa Island last year averaging 94 bets a day over our homes and at an average SENL of 84.05 db(A) which is louder than an `alarm clock or' garbage disposa.l., 1both at 80db(A). I don't r imagine there are many people who could live with an alarm clock going off near their head 94 times a day without experiencing anger and frustration at those who are causing the jarring disturbance. z On the question about noise level, I asked Vince Mestre specifically about the difference in db(A) level in the upper and lower bays because we had 'been consistently toll by the members of your Aviation Committee that the noise we suffered on Balboa Island was considerably less than the upper bay because aircraft were higher over the Island. The fact is, aircraft gain z',.very little altitude because of the power cutback and the 3,000 foot ceiling restriction (because of the over flight pattern, again over Balboa Island, of Long Beach Airport traffic). Vince Mestre told me the noise level over Balboa Island decreased less than 3db(A) (not perceptibly less to the human ear) from the noise levels in the upper bay. This is what I wanted him to restate in writing. �'- Also, according to his study 12% of the aircraft are applying thrust over the Island and therefore our noise level could actually be higher. For the purposes of noise impact Balboa Island could be visualized in the middle of the upper bay with aircraft directed immediately over us. The map you enclosed is also old news and not what I requested. It is based on 1985 data and not relevant to what is happening today other than to show clearly that the noise contours used to be farther to the west. Today the flight path cuts Balboa Island in half directly down the middle. How did this path get shifted eastward directly over us in the past three years? As for the last question of cutback/altitude/noise, Vince Mestre said he thought he had some information in his office on the subject and that was what I requested he share with us. The question definitely should be
