The average noise level measured at monitoring station NMS 10N, located at Columbus Tustin Middle School, slightly increased during the third and fourth quarters. Average noise levels during both quarters remained below the City, County, and State criteria of 65 dB Community Noise Equivalent Level (CNEL) for residential uses. RECOMMENDATION That the City Council receive and file this report. FISCAL IMPACT On December 18, 2001, the City Council authorized Wieland Associates to review JWA Noise Abatement Quarterly Reports. The costs for such reviews are annually included in the Community Development Department budget. DISCUSSION Following the conclusion of each calendar quarter, John Wayne Airport prepares a Noise Abatement Program Quarterly Report and transmits a copy of the report to the City of Tustin. Twice a year, the City's consultant prepares a report, which summarizes two quarterly reports. Attachment A contains the quarterly reports for the third and fourth quarters of 2001. Attachment B contains the summary report prepared by the noise consultant. A brief overview of the information contained within these attachments is as follows: JWA Noise Report August 5, 2002 Page 2 Measured Noise Levels During the third quarter of 2001, the average CNEL at Remote Monitoring Station (NMS) 10N, located at Columbus Tustin Middle School was 56.7 dB. This is .3 dB less than the four previous quarters. However, for comparison, the CNEL was .3 B higher (57.0) during the third quarter of 2000. During the fourth quarter of 2001, the average CNEL was 57.0 dB. This is the same average as the four previous quarters. For comparison, the CNEL was .3 dB lower (56.7) during the fourth quarter of 2000. All 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 2001, there were 17 Tustin area complaints compared with 16 for the same period during 2000. During the fourth quarter of 2001, there were 7 Tustin area complaints compared with 17 for the same period during 2000. The number of complaints decreased during the third and fourth quarters compared to the same period in 2000. The overall number of complaints dudng the last two quarters of 2001 does not appear to correlate with the average quarterly aircraft CNEL nor with the number of quarterly jet operations at the airport. The average quarterly aircraft CNEL increased steadily from the fourth quarter of 2000 through the second quarter of 2001, while the number of complaints from residents of the Tustin area remained relatively steady. The number of complaints in the fourth quarter of 2001 actually dropped even though the average quarterly CNEL increased. Type and Mix of Aircraft Related to Noise Levels During the third quarter of 2001, the percentage of quieter Class E aircraft increased and the percentage of noisier Class A aircraft decreased compared with the same period in 2000. The average CNEL for the third quarter of 2001 was slightly lower than the same period during 2000. During the fourth quarter of 2001, the percentage of quieter Class E aircraft increased and the percentage of noisier Class A aircraft decreased compared with JWA Noise Report August 5, 2002 Page 3 the same period in 2000. The average CNEL for the fourth quarter was slightly higher than the fourth qUarter of 2000. The percentage of quieter Class E aircraft using John Wayne Airport has gradually increased since the beginning of 2000. This percentage increase in Class E aircraft was offset by a decrease in the use of the noisier Class AA aircraft. Based on data from the third quarter of 2000 through the fourth quarter of 2001, there appears to be a correlation between the aircraft mix and the average quarterly CNEL at NMS 10. Airport Noise Contours Wieland and Associates, Inc. utilized a noise contour in preparing the attached report. This noise contour is based on the 2001 contours developed by the noise consultant for the John Wayne Airport Noise Abatement office. Using this contour, it is estimated that in 2001 the aircraft-generated CNEL in Tustin ranged from about 59 dB to less than 55 dB. This is well below the City, County, and State criteria of 65 dB for residential areas. 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.

Murphy Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 115th 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 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 noise monitoring stations (NMS) located in Newport Beach, Santa Ana, Tustin and Irvine to measure noise levels, at the following locations: MONITOR STATIONS NMS- 1 S: Golf Course, 3100 Irvine Ave., Newport Beach NMS-2S: 20152 S.W. Birch St., Santa Ana NMS-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-5S: 324 V2 Vista Madera, Newport Beach NMS-6S: 1912 Santiago, Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-8N: 17372 Eastman Street, Irvine NMS-9N: 1300 S. Grand Avenue, Santa Ana NMS-10N: 17952 Beneta Way, Tustin The map in Figure 1 shows the general location of each permanent remote monitor station. Figure 2 shows the Airport's "Noise Impact Area" for the previous year (October 1, 2000 - September 30, 2001). The Figure 2 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". -1- '.

Insufficient data is indicated by "#N/A" entries in each table. Average Single Event Noise Exposure Level (SENEL) values for Air Carrier and GA Jet aircraft are shown in Tables 6 through 8. For the twelve month period ending September 30, 2001, 102 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents a decrease of one unit in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending June 30, 2001. The State has approved several remedies of aircraft noise levels for noise sensitive property in the "Noise 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 Pro,am, 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 current AAIP has been renamed "Santa Ana Heights Acoustical Insulation Program" with the acronym "SAH AIP".) During the third quarter of 2001 , no additional residences have been made compatible through the County's SAH AIP. A total of 267 residences in Santa Ana Heights have been purchased or otherwise made compatible through the County's Purchase Assurance Pro,am, Housing Relocation Program, Acoustical Insulation Program or SAH AIP. TELEPHONE COMPLAINT CALLS (July 1, 2001 - September 30, 2001) The Airport's Access and Noise Office receives and investigates noise calls and complaints from local citizens and all other sources. During the period July 1,2001 through September 30, 2001, the Office received 643 complaints from citizens. This is a 13.0% increase from the 569 complaints received last quarter. It is a 2.6% decrease from the 660 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities. -5- FIGURE 4 HISTOGRAM BY COMMUNITY 180 160 140 120 100 8O 60 40 20 0 138 13 8 4 10 7 10 41 29

Murphy/ Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 116th Quarterly Report submitted by the County of Orange in accordance with the requirements of the Califomia 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 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 noise monitoring stations (NMS) located in Newport Beach, Santa Ana, Tustin and Irvine to measure noise levels, at the following locations: MONITOR STATIONS NMS- 1 S: Golf Course, 3100 Irvine Ave., Newport Beach NMS-2S: 20152 S.W. Birch St., Santa Ana NMS-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-5S: 324 V2 Vista Madera, Newport Beach NMS-6S: 1912 Santiago, Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-8N: 17372 Eastman Street, Irvine NMS-9N: 1300 S. Grand Avenue, Santa Ana NMS- 1 ON: 17952 Beneta Way, Tustin The map in Figure 1 shows the general location of each permanent remote monitor station. Figure 2 shows the Airport's "Noise Impact Area" for the previous year (January 1,2001 - December 31,2001). The Figure 2 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". -1- , FIGURE I JOHN WAYNE AIRPORT STATION LOCATION MAP JOHN WAYNE el.Ms: 3s I NMS - NOISE MONITORING STATION -2- FIGURE 2 O Noise Monitors ~ Single Family Residential 65 dB CNEL Contour ~ Multi-Family Residential STATISTICS: ~ Incompatible Land Use: 15.04 Acres or .024 square miles ~ Number of Dwellings: 102 Number of People: 255 (based on 2.5 people per dwelling unit) JOHN WAYNE AIRPORT 65 dB CNEL Impact Area Januar~ 2001 - December 2001 Mest~ Oreve /lssoc~at~s -3- AIRCRAFT TRAFFIC SUMMARY The Airport traffic summary for this quarter is shown in Table 1 and Figure 3 below.

COMMUNITY NOISE EQUIVALENT LEVELS The monthly, quarterly and twelve month Community Noise Equivalent Level (CNEL) average values for each monitor station are shown in Table 2, while daily CNEL values are shown in Tables 3 through 5. Insufficient data is indicated by "#N/A" entries in each table. Average Single Event Noise Exposure Level (SENEL) values for Air Carrier and GA Jet aircraft are shown in Tables 6 through 8. For the twelve month period ending December 31, 2001, 102 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); there was no change in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending September 30, 2001. The State has approved several remedies of aircraft noise levels for noise sensitive property in the "Noise Impact -4- 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 current AAIP has been renamed "Santa Ana Heights Acoustical Insulation Program" with the acronym "SAH AIP".) During the fourth quarter of 2001, an additional 182 residences have been made compatible through the County's SAH AIP. A total of 449 residences in Santa Ana Heights have been purchased or otherwise made compatible through the County's Purchase Assurance Program, Housing Relocation Program, Acoustical Insulation Program or SAH AIP. TELEPHONE COMPLAINT CALLS (October 1, 2001 - December 31, 2001) The Airport's Access and Noise Office receives and investigates noise calls and complaints from local citizens and all other sources. During the period October 1,2001 through December 31,2001, the Office received 207 complaints from citizens. This is a 67.8% decrease from the 643 complaints received last quarter. It is a 33.9% decrease from the 313 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.

Airport Statistics John Escobedo gave a summary on the Airport Statistics citing information published in the JWA Airport Statistics report for November 2001. He noted decreases from Novmber 2000 levels in total passengers, air cargo tonnage lifted, general aviation operations, air carrier operations, air taxi operations and total operations, due primarily to the effects of the tragic events of September 11th. 2. Status of the Santa Ana Heights Acoustical Insulation Program (SAHAIP) Carl Braatz provided an update on the status of the SAHAIP. He noted that the AIP Phase Vll, the 182 unit apartment building located at the comer of Mesa Drive and Irvine Avenue is now complete. The Notice of Completion was recorded on December 6, 2001. The total cost of insulation for the apartment building was $1.7 million. The apartment building is now in a yearlong warranty period. For AIP Phase VIII, construction is due to begin on 25 single family dwellings on January 7, 2002. An additional 10 homes are in the design phase. 3. Any additional questions None. 4. Tentative date for the next Noise Abatement Committee meeting The date for the next quarterly Noise Abatement Committee meeting will be announced by letter approximately two weeks before the meeting. -16- NAC ROSTER December 27, 2001 NAME ORGANIZATION Mark Esslinger County of Orange Cad Braatz John Wayne Airport Eric Freed John Wayne Airport Bonnie Streeter John Wayne Airport Irma Ortega John Wayne Airport John Escobedo John WayneAirport -17- Attachment B Review of John Wayne Airport Noise Abatement Program Quarterly Reports July 15, 2002 Project File 241-01 Ms. Justina Willkom City of Tustin Community Development Department 300 Centennial Way Tustin, CA 92780 Subject: Review of John Wayne Airport Noise Abatement Program Quarterly Reports for the 3rd and 4th Quarters of 2001 Dear Ms. Willkom, 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: e ge Referring to Figure 1, the average annual CNEL at NMS I0N was 57.0 dB for 2001 based upon data for all four quarters. This is 0.3 dB lower than the average annual CNEL of 57.3 dB for 2000. (NOTE: The noise contours for John Wayne Airport are based on average annual CNEL values measured at each remote monitoring station.) The average annual CNEL of 57.0 dB in 2001 implies the leveling off of a modest upward trend in the aircraft noise exposure measured at NMS 10N. This trend is illustrated in the following table: 1994 1995 1996 1997 1998 1999 2000 2001 56.1 dB 56.4 dB 56.8 dB 55.9 dB 57.0 dB 56.8 dB 57.3 dB 57.0 dB Referring to Figure 2, the number of noise complaints received from the Tustin area does not appear to correlate with the average quarterly aircraft CNEL measured at NMS 10N, nor with the number of quarterly jet operations at the airport. As indicated in the figure, the average quarterly CNEL increased steadily from the fourth quarter of 2000 through the second quarter of 2001, while the number of complaints from residents of the Tustin area remained relatively steady. The number of complaints in the fourth quarter of 2001 actually dropped even though the average quarterly CNEL increased. 1, I Average Quarterly Aircraft CNEL, NMS 10v4I ~ 58.0 ~ 56.5 i ~ 56.0 < 1Qt~O 2Qt~O 3Qt~O 4Qt~O 1Qtffil 2Qt~l 3Qtffil 4Qtffil ITotal Queerly Jet Operations, ~S 10NJ ' 22,500 ~ 22,000 ~ 19,500 ~ 1Qt~0 2Qtm0 3Qt~0 4Qtffi0 1Qt~l 2Qtffil 3Qt~l 4Qtffil I Average Quarterly Noise Complaints I · ~ 80 oD 20 > 0 < 1Qt~0 2Qt~O 3Qt~O 4Qt~O 1Qtffil 2Qt~l 3Qt~l 4Qtffil WIE~ND Average Queerly C~L, Qua~erly Jet 2 ASSOCIATE& INC. Operations, and Qua~erly Noise Complaints CITY OF TUSTIN Project File 241-01 q, , As indicated in Item 1, above, the annual average CNEL measured at NMS 1 ON was 57.0 dB in 2001. This 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. Aircraft Noise Contours Figure 3 provides the estimated location of the John Wayne Airport noise contours for 2001. These are based on the 2001 contours developed by the John Wayne Airport Noise Abatement Office, and data through the fourth quarter of 2001. Referring to Figure 3, it is estimated that in 2001 the aircraft-generated CNEL ranged from about 59 dB to less than 55 dB. This is well below the City, County, and State criteria of 65 dB for residential areas. Use of Quieter Aircraft at John Wayne Airport The correlation between the increasing use of quieter aircraft at JWA and the change in CNEL within the City of Tustin has been assessed. The Federal Aviation Administration (FAA) classifies aircraft into three categories based on noise levels. In order of decreasing noise levels, there are Stage I, Stage II, and Stage III aircraft. John Wayne Airport has only permitted Stage III aircraft since the early 1970's. 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 aircraft that used the airport between the first quarter of 2000 and the fourth quarter of 2001. Also provided is the measured average quarterly CNEL at NMS 1 ON. Table 2 provides the same information, but the values have been normalized to 17,000 aircraft operations (takeoffs and landings) per quarter. In this way, a correlation can be established between the quarterly CNEL and the mix of aircraft types. Referring to Table 2 and Figure 4, the percentage of quieter Class E aircraft using John Wayne Airport has gradually increased since the beginning of 2000. This increase in Class E aircraft was offset by a decrease in the use of the noisier Class AA aircraft. However, during this same time period, the average quarterly CNEL has been relatively steady. Therefore, based on data from the first quarter of 2000 through the fourth quarter of 2001, there does not appear to be any correlation between the aircraft mix and the average quarterly CNEL at NMS 1 ON.
