HUSTON, CITY MANAGER FROM: COMMUNITY DEVELOPMENT DEPARTMENT SUBJECT: JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORTS RECOMMENDATION ReCeive and file report. FISCAL IMPACT The City retains the acoustics consulting firm of J.J. Van Houten and Associates, Inc. for review of noise-related items. The costs for such reviews are annually included in the CommUnity Development Department budget. DISCUSSION The Community Development Department currently contracts with an acoustics consultant to review and interpret the John wayne Airport Noise Abatement Program Quarterly Reports prepared by the County of Orange. On September 21, 1987, the City Council authorized these reviews to monitor airport noise issues as a result of concerns from many Tustin residents. Twice a year, the consultant prepares a report which summarizes two quarterly reports. Attachment 1 contains the quarterly reports for the third and fourth quarters of 1996. Attachment 2 contains the summary report prepared' by the noise consultant. A brief overview of the information contained within these attachments follows. City Council Report JWA Noise Abatement Quarterly Reports May 19, 1997 Page 2 Measured Noise Levels During the third quarter of 1996, the average CNEL at Remote Monitoring Station (RAMS) #7, located at Columbus Tustin Middle School, was 55.7 dB. This is 1.1 dB less than the four previous quarters. Also, for comparison, the CNEL was the same (55.7) during the third quarter of 1995. During the fourth quarter of 1996, the average CNEL was 57.2. This is 0.3 more than the four previous quarters. For comparison, the CNEL was 0.2 higher (57.4) during the fourth quarter of 1995. Ail measured noise levels are below the City, County and State criteria of 65 dB CNEL for residential areas. Noise Complaints During the third quarter of 1996, there were 47 Tustin/Orange complaints compared with 46 for the same period during 1995. During the fourth quarter of 1996, there were 87 Tustin/Orange complaints compared with 47 for the same period during 1995. The increase in complaints may be related to the increase in the average CNEL during the 4th quarter and the number of jet operations. T_vpe and Mix of Aircraft Related to Noise Levels During the first quarter of 1996, the percentage of quieter Class E aircraft increased and the percentage of noisier Class A aircraft decreased compared with the same~ period in 1995. The average CNEL for the third quarter of 1996 was the same level as the same period during 1995. During the fourth quarter of 1996, the use of quieter Class E aircraft increased and the use of noisier Class A aircraft increased compared with the same period in 1995. However, the average CNEL for the fourth quarter of 1996 was 0.2 dB lower than the fourth'quarter of 1995. No clear correlation between CNEL and the type and mix of arriving and deParting aircraft can be determined from information in these reports or previous reports. City Council Report JWA Noise Abatement Quarterly Reports May 19, 1997 Page 3 Since noise issues are of considerable importance to the City of Tustin, the Community Development Department will continue to monitor operations at John Wayne Airport unless otherwise directed by the City Council.

APR ~ 1199T ADMi:,'I~-:':"~ ~,._., ~:,'-,~ iON NOISE ABA~ PROGRAM QUARTERLY REPORT For the period: October 1, 1996 through December 31, 1996 Prepared in accordance with: AIRPORT NOISE STANDARD STATE OF CALIFORNIA California Administrative Code Title 21, Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards Submitted by: Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 96th Quarterly Report submitted by the County of Orange in accordance with the requirements of the California Airport Noise Standards (California Administrative Code Title 21, Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards). Effective January 1, 1986, the criteria for defining "Noise Impact Area" was changed from 70 dB to 65 dB Community Noise Equivalent Level (CNEL). Under this criteria, John Wayne Airport currently has a ~Noise Impact Area." NOISE IM?ACT SUMMARY Calms' Aeronautics Program has established guidelines in the California State Noise Standard to control residential area noise levels produced by aircraft operations using the State's airports. Under those guidelines, residential noise sensitive areas exposed to an average Community Noise Equivalent Level (CNEL) of more than 65 dB define the "Noise Impact Area." John Wayne Airport uses ten permanent remote monitoring stations (RMS) located in Newport Beach, Santa Aha, Tustin and Irvine to measure noise levels, at the following locations: MONITOR STATIONS RMS- 1: Golf Course, 3100 Irvinc Ave., Newport Beach RMS-8: RMS-2:20152 S.W. Birch St., Santa Aha RMS-9: RMS-3: 2139 Anniversary Lane, Newport Beach RMS-21: RMS-6: 1131 Back Bay Drive, Newport Beach RMS-22: RMS-7: 17952 Beneta Way, Tustin RMS-24: 1300 S.

The Figure 1 information was developed by Mestre-Greve Associates, Inc., in consultation with John Wayne Airport. CNEL values measured for the period and current digitized land use information were utilized to calculate the land area acreages, number of residences and estimated number of people within the "Noise Impact Area".

For the twelve month period ending December 31, 1996, 113 dWelling units in Santa Ama Heights were in the '2qoise Impacted Area" (within the 65 dB CNEL contour); this represents an increase of 20 units in the number of dwelling units in the '2qoise Impacted Area" from the previous twelve month period ending September 30, 1996. The State has approved several remedies of aircraft noise levels for noise sensitive.property in the '~qoise Impact Area": homes can be acoustically insulated, purchased by the County, or rezoned for "other non-noise sensitive uses." As part of the County's Santa Ana Heights Land Use Compatibility Program, approximately 77 general agriculture (A- 1) properties with residential land uses on Orchard, Acacia and Birch Streets were rezoned for Business Park Use in October, 1986. Each property was individually sold and subsequently converted to compatible land use. Between 1986 and 1993, 124 residences have been purchased or otherwise made compatible through the County's Purchase Assurance Program, Acoustical Insulation Program or Housing Relocation Program. In September 1993, the FAA approved a grant to fund a voluntary Accelerated Acoustical Insulation Program (AAIP) in Santa Ana Heights. (The currem AAIP has been renamed "Santa Ama Heights Acoustical Insulation Program" with the acronym "SAH AIP".) An additional 15 residences have been made compatible through the County's SAH AlP. A total of 139 residences in Santa Ana Heights have been purchased or otherwise made compatible through the County's Purchase Assurance Program, Housing Relocation Progrmn, Acoustical Insulation Program or SA~-I AtP. TELEPHONE COMPLAINT CALLS (October- December 1996] The Airport's Access and Noise Office receives and investigates noise calls and complaints from local citizens and all other sources. During the fourth quarter of 1996, the Office received a total of 256 complaints from'local citizens, a 34.5% decre~e from the 391 complaints received during the previous quarter and a decrease of 14.0% from the 298 complaints received during the same quarter of 1995.

RG:jw K10727 3/31/97 -14- NOISE ABA~ PROGRAM QUARTERLY REPORT NAR - 5 i~7 CO~MUNITf DEV[EO' For the period: July 1, 1996 through September 30, 1996 Prepared in accordance with: AIRPORT NOISE STANDARD STATE OF CALIFORNIA California Administrative Code Title 21, Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards Submitted by: Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 95th Quarterly Report submitted by the County of Orange in accordance with the requirements of the California Airport Noise Standards (Califom Administrative Code Title 21, Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards). Effective January 1, 1986, the criteria for defining 'Noise Impact Area' was changed from 70 dB to 65 dB Community Noise F_quivalent Level (CNEL). Under this criteria, John Wayne Airport currently has a 'Noise Impact Area.' NOISE IMPACT SUMMARY Caltrans' Aeronautics Program has established guidelines in the California State Noise Standard to control residential area noise levels produced by aircraft operations using the State's airports. Under those guidelines, residential noise sensitive areas exposed to an average Community Noise Equivalent Level (CNEL) of more than 65 dB define the "Noise Impact Area.' John Wayne Airport uses ten permanent remote monitoring stations (RMS) located in Newport Beach, Santa Aha, Tustin and Irvine to measure noise levels, at the following locations: MONITOR STATIONS RMS-I: GolfCoursc, 3100 Lwin~Ave.,N~rtBeach RMS-8: RMS-2:20152 S.W.

The Figure 1 informatiofi was developed by Mestr~-Greve Associates, Inc., in consultation with lohn Wayne Airport. CN'FJ. values measured for the period and current digitized land use infomtion were utilized to calculate the land area acreages, number of residences and estimated number of people within the 'Noise Impact Area'.

For the twelve month period ending September 30, 1996, 93 dwelling units in Santa Aha Heights were in the "Noise Impac~l Area" (within the 65 dB CNEL contour); there was an increase of 22 units in the number of dwelling units in the "Noise Impacted .Area" fi.om the previous twelve month period ending June 30, 1996. The State has approved several remedies of aircraft noise levels for noise sensitive property in the '~oise Impact Area": homes can be acoustically insulated, purchased by the County, or rezoned for "other non-noise sensitive uses." As part of the County's Santa Ama Heights Land Use Compatibility Program, approximately 77 general agriculture (A- 1) properties with residential land uses on Orchard, Acacia and Birch Streets were rezoned for Business Park Use in October, 1986. Each Property was individually sold and subsequently converted to compatible land use. Between 1986 and 1993, 124 residences have been purchased or otherwise made compatible through the County's Purchase Assurance Program, Acoustical Insulation Program or Housing Relocation Program.. In September 1993, the FAA approved a grant to fund a voluntary Accelerated Acoustical Insulation Program (AA.IP) in Santa Aha Heights. (The current AAIP has been renamed "Santa Ana Heights Acoustical Insulation Program" with the acronym "SAH AI?'.) An additional 15 residences have been made compatible through the County's SAH AIP. A total of 139 residences in Santa Aha Heights have been purchased or otherwise made compatible through the County's Purchase Assm2nce Program, Housing Relocation Program, Acoustical Insulation Program or SAH AIP.

"Data Evaluation and Aircraft Noise Impact Study for the City of Tustin," J. J. Van Houten and Associates, Inc., January 8, 1990 2. "Noise Abatement Program Quarterly Report for the Period: July 1, 1996 through September 30, 1996," John Wayne Airport 3. "Noise Abatement Program Quarterly Report for the Period' October 1, I996 through December 31, 1996," John Wayne Airport Dear Ms. BinSack, As requested, we have reviewed the referenced quarterly reports for the noise abatement program at 'John Wayne Airport. The following provides our findings with regard to airport operations and their impact on the City of Tustin: 1. Referring to Figures 1 and 2, the average annual CNEL at station M7 was 56.8 dB for 1996 based upon data for all four quarters. This is 0.4 dB higher than the average annual CNEL of 56.1 dB for 1994. (NOTE: The noise contours for John Wayne Airport are based on average annual CNEL values measured at each remote monitoring station.) 2. Referring to Figure 2, the number of noise complaints has increased significantly in the 4th quarter of 1996. This corresponds with the CITY OF TUSTIN Project File 2306-91 increase in average quarterly CNEL during the fourth quarter of 1996 and with the increase in average quarterly number of jet operations during the same time period. 3. As indicated in Item 1, above, the annual average CNEL measured at station M7 was 56.8 dB based on information through the fourth quarter of 1996. Th/s is slightly less than the 58 dB that was estimated for the station in the referenced aircraft noise impact study for the Phase 2 Access Plan (Reference 1).. AIRCRAFT NOISE CONTOURS In 1988, an exterior aircraft noise monitoring effort was conducted throughout the City of Tustin by the John Wayne Airport Noise Abatement Office and by J. J. Van Houten and Associates, Inc. (Reference 1). Aircraft-generated single event noise exposure levels (SENEL's) were measured at twelve locations in Tustin over a five month period. AS a result of this effort, noise contours were developed for John Wayne Airport as they impact the City of Tustin. Although the shape of the contours does not change (since flight tracks are fixed), the value of the noise contours does change with different levels of operationS at the airport and different m/xes of aircrafL Figure 3 provides the approximate location of the John Wayne Airport~ noise contours for 1990 based on measurements obtained at monitoring station M7 throughout the year. Referring to the figure, the community noise equivalent level (CNEL) ranged from 53 to 59 dB in the City of Tustin, with a CNEL of about 55 dB at station M7. Based on data through the fourth quarter, the annual average CNEL at station M7 was 56.8 dB in 1996. The existing and future Phase 2 contours (based on 1996 data) are provided in Figure 4. Referring to the figure, it is estimated that in 1996 the aircraft-generated CNEL ranged from 55 to 61 dB. This is well below the City, County, and State criteria of 65 dB for residential areas. USE OF QUIETER AIRCRAFT AT JWA AS requested, we have analyzed the correlation between the increasing use of quieter aircraf~ at JWA and the change in CNEL within the City of Tustin. The Federal Aviation Administration (FA_A) classifies aircraf~ into three categories based on noise levels. In order of decreasing noise levels, there are Stage I, Stage I1, and Stage 1I[ aircraft. John Wayne Airport has only permitted Stage Ir[ aircraf~ since the early 1970%. The airport has its own classification scheme for passenger aircraft. In order of decreasing noise level, these are Class A, Class AA, and Class E aircraft. Table 1 provides the estimated number of each class of aircraf~ that used the airport between the first quarter of 1995 and the fourth quarter of 1996. Also provided is the measured average quarterly CNEL at monitoring station M7. Table 2 provides the same information, but the values have been normalized to 17,000 aircraf~ operations (takeoffs and landings) per quarter. In this way, a correlation can be established between the quarterly CNEL and the mix of aircrat~ types. J. J. VAN HOUTEN & ASSOCIATES, INC. CrT'Y OF TUSTIN P,-ojc~ Fiic 2306-91 Referring to Table 2 and Figure 5, the percentage of quieter Class E aircraft using John Wayne Airport was higher in the 4th quarter of 1996 than in the 3rd quarter (about 36%). This increase in Class E aircraf~ were offset by decrease in the use of the noisier Class A aircraft. However, even with this decrease in noisier aircraft the weighted average quarterly CNEL increased. If You have any questions, please contact the undersigned at 714/476-0932. Very truly yours, J. J.
