NOISE ABATEMENT PROGRAM QUARTERLY REPORT For the period: July 1, 2003 through September 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 Submitted by: kUL- Alan L. Murphy ~ Airport Director John Wayne Airport, Orange County RECEIVED DEC 2 6 2003 COMMUNITY DEVELOPMENT INTRODUCTION This is the 123rd Quarterly Report submitted by the County of Orange in accordance with the requirements ofthe California Airport Noise Standards (California Administrative Code Title 21, Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards). Effective January I, 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 ST A nONS NMS-1S: 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 Y2 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-lON:17952 Beneta Way, Tustin The map in Figure I shows the general location of each permanent remote monitor station. Figure 2 shows the Airport's "Noise Impact Area" for the previous year (October 1,2002- September 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". -1- FIGURE 1 JOHN WAYNE AIRPORT STATION LOCATION MAP a.vo "" '- ~ NMS - NOISE MONITORING STATION -2:"" FIGURE 2 0 Noise Monitors D Single Family Residential 65 dB CNEL Contour D Multi-Family Residential N STATISTICS: + Incompatible Land Use: 9.0 Acres or .014 square miles Number of Dwellings: 84 Number of People: 210 (based on 2.5 people per dwelling unit) JOHN WAYNE AIRPORT 65 dB CNEL Impact Area October 2002 - September 2003 Mestre Greve Associates -3- AIRCRAFT TRAFFIC SUMMARY The Airport traffic summary for this quarter is shown in Table I and Figure 3 below.

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 "#IN/A" entries in each table. A verage 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 September 30, 2003, 84 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents a decrease of 2 units in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending June 30, 2003. -4- 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 3rd quarter of 2003, no additional residences have been made compatible through the County's SAH AlP. 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 AlP. TELEPHONE COMPLAINT CALLS (July 1. 2003 . September 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 July 1,2003 through September 30,2003, the Office received 515 complaints from citizens. This is a 61.9% increase from the 318 complaints received last quarter. It is a 15.7% increase from the 445 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.

Mnrphy ~ Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 124 Quarterly Report submitted by the County of Orange in accordance with the requirements ofthe California Airport Noise Standards (California Administrative Code Title 21, Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards). Effective January I, 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-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-6S: 1912 Santiago, Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-8N: 17372 Eastman Street, Irvine NMS-1S: Golf Course, 3100 Irvine Ave., Newport Beach NMS-2S: 20152 S.W. Birch St., Santa Ana NMS-5S: 324 '12 Vista Madera, Newport Beach NMS-9N: 1300 S. Grand Avenue, Santa Ana NMS-lON: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 1,2003 - December 31,2003). 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". -1- FI GURE 1 JOHN WAYNE AIRPORT NOISE MONITORING STATIONS (NMS) LOCA TI 0 N MAP 3 Nt Scale In miles JW AdivisionPr 0 jec tlGovts,CommRelotion/ obnomost. dgn -2- 0 Noise Monitors 0 Single Family Residential 65 dB CNEL Contour 0 Multi-Family Residential STATISTICS: N Incompatible Land Use: 8.0 Acres or .012 square miles + Number of Dwellings: 85 Number of People: 213 (based on 2.5 people per dwelling unit) JOHN WAYNE AIRPORT 65 dB CNEL Impact Area January 2003- December 2003 Mestre Greve Associates -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 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 Business Jet aircraft are shown in Tables 6 through 8. For the twelve month period ending December 31, 2003, 85 dwelling units in Santa Ana Heights were in -4- 3/31/04 the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents an increase of 1 unit in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending September 30,2003. 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-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 4th quarter of 2003, no additional residences have been made compatible through the County's SAH AlP. 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 AlP. TELEPHONE COMPLAINT CALLS (October 1.2003 - December 31. 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 October 1, 2003 through December 31,2003, the Office received 192 complaints from citizens. This is a 62.7% decrease from the 515 complaints received last quarter. It is a 16.2% decrease from the 229 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.

Additional topic discussions and/or comments and Questions Question: Pete Drummond, a Dover Shores resident and member of the A WG, states that many air carriers departing fly on the west side or east side of the back bay and asked why all the carriers don't fly straight down the back bay. Answer: Eric Freed explained that past inquiries made to the FAA regarding departure tracks over the back bay were determined to be acceptable and that track variances over a community over a period of time average out. Eric Freed suggested to Pete that he view the flight tracks via Airport Monitor and gave Pete a demonstration on the use of Airport Monitor. 4.
