Murphy Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 121st 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 Caitrans' 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 kvine to measure noise levels, at the following locations: MONITOR STATIONS NMS-1S: Golf Course, 3100 Itvine Ave., Newport Beach NMS-2S: 20152 S.W. Birch St., Santa Ana NMS-3S: 2139 Anniversary Lane, Newport Beach NMS4S: 2338 Tustin Ave., Newport Beach NMS-5S: 324 V2 Vista Madera, Newport Beach NMS45S: 1912 Santiago, Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-SN: 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 (April 1, 2002 - March 31, 2003). The Figure 2 infoxmafion 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 NMS - NOISE MONITORING STATION I~GIIEE 2 O Noise Monitors [-~ Single Family Residential 65 dB CNEL Contour ~ Multi-Family Residential STATISTICS: + Incompafi~e Land Use: 9.6 Acres or .015 square miles Number of Dwellings: 87 Number of People: 218 (based on 2.5 people per dwelling unit) JOHN WAYNE AIRPORT 65 dB CNEL Impact Area April 2002 - March 2003 -3- AIRCRAFT TRAFFIC SUMMARY The Airport traffic summary for this quarter is shown in Table I and Figure 3 below.

COMMUNITY NOISE E~)UIVALENT 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 Business Jet aircraft are shown in Tables 6 through 8. For the twelve month period ending March 31, 2003, 87 dwelling units in Santa Ana Heights were in the -4- 6/5/03 "Noise Impacted Area" (within the 65 dB CNEL contour); this represents an increase of 8 units in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending December 31, 2002. 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~ 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 Aha Heights Acoustical Insulation Program" with the acronym "SAH Alp".) During the first quarter of 2003, no additional residences have been made compatible through the County's SAH AlP. A total of 473 residences in Santa Aha 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 (January 1, 2003 - March 3L 2003) 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 l, 2003 through March 31, 2003, the Office received 278 complaints from citizens. This is a 21.8% increase from the 229 complaints received last quarter. It is a 22.9% decrease from the 361 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 February 2003. He noted that passenger traffic and operational levels for commercial and commuter traffic increased while total operations and general aviation traffic decreased when compared to February 2002. 2. Status of the Santa Ana Heights Acoustical Insulation Program (SAHAIP) Carl Braatz provided an update on the status of the SAHAIP. The 9th Phase of the SAHAIP consisting of 8 dwellings are scheduled for completion in April 2003. Construction bids for an additional 15 dwellings will be due in mid April. In June of 2003, the FAA will withdraw its funding of the program. 3. Additional topic discussions and/or comments and questions Eric Freed gave an update on the Airport's efforts to bring a web-based flight track display system to the community. In March 2003, the Board of Supervisors awarded Megadata Corporation the contract to install Airport Monitor the web-based flight tracking system at JWA. A 30 day testing period will follow installation with a web-site release date to the community in mid June 2003. Eric Freed provided an update on the extension of the JWA Settlement Agreement. The extension has been signed by all parties. Staff Report out for comment and will close mid April. Extension to Board of Supervisors for review and consideration in June 2003 with new allocation capacity to air carriers by July 1, 2003. Question: Joe Deaton, a Balboa Island resident, asked are all new allocations going to air carriers and how can you allocate new flights with the current available gates. Answer: Eric Freed explained that the new capacity flight allocations would go to the incumbent air carders and two new air carriers on the new entrant waiting list. Plans are under way for new gate build-outs at the terminal to accommodate the gradual implementation of this new capacity at JWA. -17- 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. -18- NAME Joe Deaton Steve DiGerlando Carl Braatz Eric Freed John Escobedo Ramey Gonzalez NAC ROSTER April 3, 2003 ORGANIZATION Balboa Island Resident Congressman Cox's Office John Wayne Airport John Wayne Airport John Wayne Airport John Wayne Airport -19- NOISE ABATEMENT PROGRAM QUARTERLY REPORT For the period: April 1, 2003 through June 30, 2003 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 John Wayne Airport, Orange County INTRODUCTION This is the 122nd 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 Aha, 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 ~ 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 (July 1, 2002 - June 30, 2003). 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". -l- FIG~IRE 1 JOHN WAYNE AIRPORT STATION LOCATION MAP JOHN WAYNE >UNTY NMS - NOISE MONITORING STATION FIGURE 2 O Noise Monitors ~ Single Family Residential 65 dB CNEL Contour ~ Multi-Family Residential STATISTICS: .~ Incompatible Land Use: 9.3 Acres or .0145 square miles Number of Dwellings: 86 Number of People: 215 (based on 2.5 people per dwelling unit) JOHN WAYNE AIRPORT 65 dB CNEL Impact Area July 2002 - June 2003 -3- AIRCRAFT TRAFFIC SUMMARY The Airport traffic summary for this quarter is shown in Table 1 and Figure 3 below.

(2) Counts in this column are based upon records provided by the local FAA representatives. 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 Business Jet aircraft are shown in Tables 6 through 8. For the twelve month period ending June 30, 2003, 86 dwelling units in Santa Ana Heights were in the -4- 8/14/03 "Noise Impacted Area" (within the 65 dB CNEL contour); this represents a decrease of I unit in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending March 31, 2003. 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-l) 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 2nd quarter of 2003, no additional residences have been made compatible through the County's SAH AIP. A total of 473 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 (April 1, 2003 - June 30~ 2003) 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, 2003 through June 30, 2003, the Office received 317 complaints from citizens. This is a 13.6% increase from the 279 complaints received last quarter. It is a 5.1% decrease from the 334 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.
