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 transmits a copy of the report to the City of Tustin. Attachment 1 contains the quarterly reports for the first and second quarters of 2004. A brief overview of the information contained within the attachment is as follows: Measured Noise Levels . During the first quarter of 2004, the average CNEl at Remote Monitoring Station (NMS) 10N, located at Columbus Tustin Middle School was 57.3 dB. This is a negligible 0.2 dB higher than the previous four quarters. However, for comparison, the CNEL was the same (57.3) during the first quarter of 2003. JWA Noise Report April 18,2005 Page 2 . During the second quarter of 2004, the average CNEL was 57.4 dB. This is .a negligible 0.3 dB higher than the previous four quarters. For comparison, the CNEL was 0.2 dB higher (57.6) during the second quarter of 2003. . 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 2004, there were 3 Tustin area complaints compared with 5 complaints for the same period during 2003. .

NOISE ABATEMENT PROGRAM QUARTERLY REPORT For the period: January 1,2004 through March 31, 2004 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 ~tted by: (¿K:P¿Z Y \ Airport Director John Wayne Airport, Orange County RECEIVED JUN 0 1 2004 COMWNITY DEVELOPMENT INTRODUCTION This is the 125 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 I, 1986, the criteria for derIDing "Noise Impact Area" was changed ITom 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 hvine 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 \I, Vista Madera, Newport Beach NMS-6S: 1912 Santiago, Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-8N: 17372 Eastman Street, mine NMS-9N: 1300 S. Grand Avenue, Santa Ana NMS-10N: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 (April I, 2003 - March 31,2004). 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 GORE 1 - - - --~-------------------~------~-- - II JOHN WAYNE AIRPORT NOISE MONITORING STATIONS (NMS) LOCATION MAP "t ",", 10 m"~ JWM,¡,¡ooPcoj"'/Co,,&CommR,,,tioo/oboomo,'.dgo -2- FI CURE 2 I 0 Noise Monitors D Single Family Residential , 65 dB CNEL Contour D Muiti-Famiiy Residentiai STATISTICS: + incompatibie Land Use: 8.5 Acres or .013 square miles N Number of Dweilings: 86 Number of People: 215 (based on 2.5 people per dweiling unit) I JOHN WAYNE AIRPORT i 65 dB CNEL Impact Area April 2003- March 2004 M,,'" G,',~ A"DC!"'" -3- AIRCRAFT TRAFFIC SUMMARY The Airport traffic summary for this quarter is shown in Table 1 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 "#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, 2004, 86 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents a decrease of 1 unit in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending December 31, 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 (AA1P) in Santa Ana Heights. (The current AA1P has been renamed "Santa Ana Heights Acoustical Insulation Program" with the acronym "SAH AlP".) During the 1st quarter of 2004 , no additional residences have been made compatibJe 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 (Januarv 1.2004 - March 31. 2004) 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 I, 2004 through March 31, 2004, the Office received 204 complaints from citizens. This is a 6.3% increase from the 192 complaints received last quarter. It is a 26.9% decrease from the 279 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.

Effective January 1, 1986, the criteria for defining "Noise Impact Area" was changed ITom 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-2S: 20152 S.W. Birch St., Santa Ana 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-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-5S: 324 Y, Vista Madera, Newport Beach NMS-ION: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 (July I, 2003 - June 30, 2004). The Figure 2 information was developed by Mestre-Greve Associates, Inc., in consultation with John Wayne Airport.

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 June 30, 2004, 90 dwelling units in Santa Ana Heights were in the -4- 8/t7/O4 "Noise Impacted Area" (within the 65 dB CNEL contour); this represents an increase off our units in the number of dwelling units in the "Noise Impacted Area" tTom the previous twelve month period ending March 31, 2004. 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 residentia11and 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 2004, 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, Acoustica11nsulation Program or SAH AlP. TELEPHONE COMPLAINT CALLS (April.. 2004 - June 30.2004) The Airport's Access and Noise Office receives and investigates noise calls and complaints tTom local citizens and all other sources. During the period April 1, 2004 through June 30, 2004, the Office received 312 complaints tTom citizens. This is a 52.2% increase tTom the 205 complaints received last quarter. It is a 1.9% decrease from the 318 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.
