HUSTON, CITY MANAGER COMMUNITY DEVELOPMENT DEPARTMENT ,)OHN XAYNE AIRPORT NOISE STUDY - UPDATE RECOI~ENDATION Receive and file. DISCUSSION A letter from the City Manager was sent to George Rebella, Airport Manager on January 15th,. inquiring about the status of the noise monitoring program, with emphasis on the Test and Procedures Guidelines, and a request for information about the LDA test results. A copy of this letter was provided to each councilmember. No response has been received as of the writing of this report. ~s soon as one is received, staff will forward it to the Council. In preparation for commencing a limited noise measurement program, the City's consultant, John Van Houten, has been plotting the location of residences of complaints received by the City on a map. He and his staff have also been locating and drawing the CNEL noise contour levels within the City based on the Airport EIR (EIR 508). Mr. Van Houten and his staff began visiting the sites of the complatntant's residences (a total of six) on January 22nd. Upon completion of their visits, they will select two to three sites which offer the best acoustic environment in which to measure aircraft noise. Measurements will be taken inside as well as outside. A future progress report will be sent to the City discussing field activity and data analysis as it occurs (if work concludes prior to start-up of JWA's program, the status reports will lapse until activity renews). A copy of the first report is attached. ~teve Rubin Seni or P1 anner · ne hlngl~ton Director of CommunityC~evelopment SR:pef Attachment: Progress report from J. J. Van Houten Associates, Inc. J. J.

WIELAND, Senior Engineer MIKE SANG LiE, Associate Engineer January 22, 1988 Project File 1890-87 CITY OF TUSTIN 300 Centennial Way Tustin, CA 92680 Attention: Mr. Steven Rubin Subject- Progress Report - Aircraft Noise Study in the City of Tustin Gentlemen: To date, the following progress has been made on the noise study our firm is performing with regard to flight operations over the City of Tustin into John Wayne Airport- 1. A map has been prepared which identifies the following (refer to attached figure): a. Location of flight tracks 5, 8B, and 8C. b · Approximate location of the CNEL contours generated by flight operations at JWA assuming a "worst case" scenario '(i.e., all flights occur on tracks 5 and 8C over the central city area)· C · Location of residents who have written complaints regard- ing aircraft noise-. These are identified as positions 1 through 6 on the figure· The names and addresses of the residents corresponding to these positions are provided in Table 1. d. Location of JWA noise monitoring position M-5 at Columbus Tustin Intermediate School, 17952 Beneta Way. · All of the six complaint sites as well as noise station M-5 were visited on January 22, 1988 in determine their suitability for noise measurements. lowing summarizes our findings: monitoring order to The fol- a · Position 1 (14351 Eh-len Avenue): Suitable si.te for monitoring· There are some trees in the yard, clear line-of-sight exists to the flight track. was home during the vi sit. noise but a Nobody CITY O? TUSTIN PROJECT FILE 1890-87 b. Position 2 (17901 Lucero Way): Site has good visibility to the east and west towards the flight track. Visibility to the north is inhibited by tall trees. The pool pump, if running, will need to be shut off. Ms. Joan Jacques, who filed the complaint, has since moved. The current owner is Ms. Shirley Schneider. She was not home during the visit. c. Position 3 (17781 Lucero Way): Difficult to view rear yard. There appears to be clear line-of-sight east and west towards the flight tracks. Trees on the north block the line-of-sight in that direction. Traffic on Prospect is-a potential problem; therefore, measurements with 20' high boom microphone would not be appropriate. Nobody was home during the visit. d. Position 4 (13471 Falmouth PIace): We interviewed Mr. Knox abOut his complaint and found that it was in reference to a single occurrence. He had,no complaints about regular flight operations at John Wayne Airport. because of this, and because the site is so distant from the flight tracks, this location has been eliminated from consideration. e. Position 5 (14382 Harp Court): This location has clear line-of-sight to the flight track. The owner, M~s. Dal- ton, is receptive to having measurements performed and will discuss it with her husband. f. Position 6 (17831 Norwood Park): This site has a number of difficulties associated with it, including two dogs at the house as well as numerous other dogs in the neighbor- hood. Also, a large garage and patio cover make the use of a 5' high microphone impractical since they block the line-of-sight to the flight track. Therefore, the microphone would have to be placed on a 20' high boom if a measurement was .deemed necessary at this site. Nobody was home during the visit. g. Noise monitoring station M-5 (17952 Beneta Way): This site is located on the campus of Columbus Tustin Inter- mediate School. While the location provides good line- of-sight to the flight track, it would be difficult to provide adequate security and to minimize interference from students in the area. J. J.

We will attempt to contact the above residents and, weather permitting, begin the noise measurement phase of the 'study on January 25-26.
