The average noise level measured at monitoring station NMS 10N, located at Columbus Tustin Middle School, remained relatively the same during the first and second 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 No Fiscal Impact DISCUSSION Following the conclusion of each calendar quarter, John Wayne Airport prepares a Noise Abatement Program Quarterly Report and posts a copy of the report on their webpage. Attachment 1 contains the quarterly reports for the first and second quarters of 2006. A brief overview of the information contained within the attachment is as follows: Measured Noise Levels . During the first quarter of 2006, the average CNEL at Remote Monitoring Station (NMS) 10N, located at Columbus Tustin Middle School was 57.0 dB. This is 0.2 dB lower than the previous four quarters. However, for comparison, the CNEL was 0.7 dB higher (57.7) during the first quarter of 2005. . During the second quarter of 2006, the average CNEL was 57.6 dB. This is 0.1 dB higher than the previous four quarters. For comparison, the CNEL was 0.1 dB lower (57.5) during the second quarter of 2005. . All measured noise levels are below the City, County, and State criteria of 65 dB CNEL for residential areas. Noise Complaints . During the first quarter of 2006, there was one (1) Tustin area complaint compared with two (2) complaints for the same period during 2005. . During the second quarter of 2006, there were twenty-three (23) Tustin area complaints compared with four (4) complaints for the same period during 2005. This increase is typical during this reporting period since residents have a tendency to leave their windows open during warmer weather. . The number of complaints decreased during the first quarter and increased during the second quarter compared to the same periods in 2005. 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 / 5 Airport Director ( John Wayne Airport, Orange County INTRODUCTION This is the 133 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-lS: 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 ~ 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-I0N: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 (Aprill, 2005 - March 31, 2006). 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- F i ure 1 -I I I I JOHN WAYNE AIRPORT NOISE MONITORING STATIONS (NMS) LOCATION MAP *l ~ H @ ~~ o I 3 I I " "" p " " I JW AdlVISlon ro Ject/Govt&CommRelabon/ abnomo~~~~ 7:;~\'_____ :0 ."! t . . ....., ~.

COMMUNITY NOISE EOUIV ALENT 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 General Aviation Jet aircraft are shown in Tables 6 through 8. For the twelve month period ending March 31, 2006, 77 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents no change in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending December 31, 2005. (Previous Quarterly Reportfor period October 1,2005 through December 31, 2005, for the twelve month period ending December 31, -4- 2005 should have reflected 77 dwelling units in the Santa Ana Heights Noise Impact Area which represented a 24 unit reduction from the previous 12 month period ending September 30. 2005.) 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 Program, approximately 77 general agriculture (A-I) 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 AlP".) During the first quarter of 2006, no additional residences have been made compatible through the County's SAH AlP. A total of 486 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 AlP. TELEPHONE COMPLAINT CALLS (Januarv 1.2006 - March 31.2006) The Airport's Access and Noise Office receives and investigates noise calls and complaints from local citizens and all other sources. During the period January], 2006 through March 31, 2006, the Office received 132 complaints from citizens. This is a 10.9% increase from the 119 complaints received last quarter. It is a 24.1 % decrease from the 174 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 The JW A Airport Statistics Report for February 2006 ,was distributed to attendees; 2. Additional topic discussions and/or comments and auestions '. Joe Deaton asked for the definition of a commuter aircraft. Eric Freed and David Chan gave the definition of a commuter aircraft as an aircraft that is configured with not more than 70 . passenger seats and an operating gross takeoff weight of not more than ninety thousand pounds. Mr. Richard Cox reported that he continues to work with Senator Boxer and Congressman Campbell's office to get relief for south coastal communities. Mr. Cox is also in contact with the FAA SOCAL TRACON, and has asked them to consider crossing aircraft over the Laguna Beach area at 9,000 or above. Several attendees asked questions in regards to aircraft making multiple approaches, low flying helicopters, and changing flight path course and altitudes. Noise Office staff explained that they were FAA issues and that JW A did not have jurisdiction over those matters. Charles Griffin stated that he was working with Shirley Konger to promote a sharp left turn after take-off for commercial aircraft and wanted to know what would be the process for changing the standard departure. Eric Freed stated that they would need to contact the FAA because that was an FAA issue. Joe Deaton asked about a newspaper article reporting increased flights out of JW A and asked what the total increase per day would be. Eric Freed advised that the total flights per day would roughly stay the same due to some deleted flights. Greg Carroll asked if a huge growth in private flights could be expected. Eric Freed advised that JW A can't place a limit on general aviation flights, but that there can be physical capacity limitations. Tentative date for the next Noise Abatement Committee meeting will be March 16,2006. -16- NAC ROSTER March 16, 2006 NAME ORGANIZATION Eric Freed Bonnie Frisch David Chan Judy Johnson Richard A.

Murphy Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 134th 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-1S: Golf Course, 3100 Irvine Ave., Newport Beach NMS-6S: 1912 Santiago, 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 ~ Vista Madera, 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-ION: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 (July 1, 2005 - June 30, 2006). 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- Fi ure 1 JOHN WAYNE AIRPORT NOISE MONITORING STATIONS (NMS) LOCATION MAP KUYb f OAnF" r ~_~ ~ n~--' -- ~ '.

(2) Counts in this column are based upon records provided by the local FAA representatives. COMMUNITY NOISE EOUIV ALENT 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 General Aviation Jet aircraft are shown in Tables 6 through 8. -4- 8/1/06 For the twelve month period ending June 30, 2006, 75 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents a decrease of two units in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending March 31, 2006. 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 Program, approximately 77 general agriculture (A-I) 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 AlP".) During the second quarter of 2006, no residences have been made compatible through the County's SAH AlP. A total of 486 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 AlP. TELEPHONE COMPLAINT CALLS (April L 2006 - June 30. 2006) The Airport's Access and Noise Office receives and investigates noise calls and complaints from local citizens and all other sources. During the period April 1, 2006 through June 30, 2006, the Office received 357 complaints from citizens. This is a 168.40/0 increase from the 133 complaints received last quarter. It is a 58.0% increase from the 226 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 Bonnie Frisch summarized the statistics from the JW A Airport Statistics Report for May 2006. 2. Additional topic discussions and/or comments and questions Richard Cox reported that there has been an improvement in departures over Emerald Bay, and that he is making good progress with FAA on this issue. Marlena McDermott added that the situation has improved in Emerald Bay except on Friday and Saturday mornings. Richard Cox stated that the last monitoring he did was over the holiday weekend, and that he saw hours at a time with all aircraft crossing the coastline over Emerald Bay at 9,000 to 10,000 feet and over, and then saw a couple in a row very low at 4,500 to 5,000 feet. He noted that it was never consistently the same air carrier. Melinda Seely asked what caused the positive change over Emerald Bay. Richard Cox responded that is was the result of working with air carriers and sending letters to the airlines asking them to be good neighbors. He explained that sometimes it is necessary for aircraft to cross the coastline at low altitudes due to other nearby traffic. William Filbert stated that he had noticed a change in the approach patterns and wondered why. Eric Freed responded that the tracks are usually pretty consistent overall, but that variations occur due to FAA Air Traffic Control sequencing of aircraft and turning the aircraft at different points along the approach path. William Filbert asked what can be done to make changes to the approach routing. Eric Freed responded that JW A can provide flight track information, but that only the FAA has control over aircraft routing. -16- William Filbert noted that the problem is especially bad on Sunday evenings. He stated that generally the planes are getting quieter due to newer technology, except for the MD80s. Joe Deaton asked how JW A addresses excessively noisy general aviation aircraft. Eric Freed described the noise limits at the monitors and the "3 strikes you're out" violation process. He added that JW A has an average of 200 violations per year, with approximately 150 first violations, 40 second violations and 10 to 15 third violations, showing that in most cases people are interested in doing the right thing. 3. Tentative date for next meeting September 14,2006 is the tentative date for the next Noise Abatement Committee meeting. -17-
