AGENDA REPORT MEETING DATE: FEBRUARY 3, 2009 TO: WILLIAM A. HUSTON, CITY MANAGER FROM: COMMUNITY DEVELOPMENT DEPARTMENT Agenda Item 6 Reviewed: City Manager Finance Director N/A SUBJECT: JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORTS SUMMARY: This report transmits two John Wayne Airport Noise Abatement Quarterly Reports for the first and second quarters of 2008. The average noise level measured at monitoring station NMS 10N, located at Columbus Tustin Middle School on Beneta Way, remained relatively constant 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 website. Attached are the quarterly reports for the first and second quarters of 2008. A brief overview of the information contained within the attachment is as follows: Measured Noise Levels During the first quarter of 2008, the average CNEL at Remote Monitoring Station (NMS) 10N, located at Columbus Tustin Middle School, was 57.2 dB. This is 0.1 dB higher than the previous four quarters (Q-1 2007 through Q-4 2007). For comparison, the CNEL was 0.5 dB lower (56.7 dB) during the first quarter of 2007. JWA Noise Report February 3, 2009 Page 2 • During the second quarter of 2008, the average CNEL was 57.1 dB. This is 0.1 dB lower than the previous four quarters (Q-2 2007 through Q-1 2008). For comparison, the CNEL was 0.5 dB higher (57.6) during the second quarter of 2007. • 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 2008, there were twelve (12) Tustin area complaints, compared with eight (8) complaints for the same period during 2007. • During the second quarter of 2008, there were eight (8) Tustin area complaints, compared with eight (8) complaints for the same period during 2007. • The number of complaints in 2008 increased 50.0% during the first quarter compared to the same period in 2007, and remained the same during the second quarter compared to the same period in 2007. The increase from Q1 2007 to Q1 2008 echoes a trend experienced over all communities during this period. The 247 complaint calls received by the Airport Access and Noise Office in Q1 2008 represents a 57.3% increase from the previous quarter (Q4 2007) and a 38.0% increase over the number of complaints received during the same period in the previous year (Q1 2007). The Access and Noise Office suspects that this period represents a peak level of calls due to repeat complaints from "regular callers." Office staff explained that preliminary data from quarters three and four of 2008 show a significant decline in complaints from these "regular callers," which was likely skewing the data during the subject period. The level of complaints, however, remained even from Q2 2007 to Q2 2008, which is a more typical reflection of citizen noise complaints. 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.

Binsack Community Development Director Attachments: John Wayne Airport Noise Abatement Quarterly Reports for January 1, 2008 through March 31, 2008 and April 1, 2008 through June 30, 2008. S:\Cdd\CCREPORT\JWA report to council 1-20-09.doc ATTACHMENTS John Wayne Airport Noise Abatement Quarterly Reports for January 1, 2008 through March 31, 2008 (Q1) and April 1, 2008 through June 30, 2008 (Q2) NOISE ABATEMENT PROGRAM QUARTERLY REPORT For the period: January 1, 2008 through March 31, 2008 Prepared in accordance with: AII2PORT NOISE STANDARD STATE OF CALIFORNIA California Administrative Code Title 21, Chapter 2.5, Subchapter 6: Division of Aeronautics Noise Standards Submitted by: Alan L. Murphy Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 141st 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: 20162 S.W. Birch St., Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-SS: 324 Yz Vista Madera, 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 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, 2007 -March 31, 2008). 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 Figure 2 -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 Carver and General Aviation Jet aircraft are shown in Tables 6 through 8. For the twelve month period ending March 31, 2008, 77 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents an increase of two dwelling units in the "Noise Impacted Area" from the previous twelve month period ending December 31, 2007. -4- Four hundred and eighteen residences in the Santa Ana Heights area have been sound attenuated and an avigation easement reserved through the County's Acoustical Insulation Program. The County has also acquired 46 residences as part of the Purchase Assurance Program, many of which were acoustically insulated, an avigation easement reserved and then resold. Among these County acquired homes, those located within areas designated for Business Park uses were razed, avigation easements were reserved, and the land resold for compatible Business Park uses. A total of 464 residences in the Santa Ana Heights area have been purchased or otherwise made compatible through the County's Purchase Assurance and Acoustical Insulation Programs. A number of residences also chose not to participate in the County's Acoustical Insulation and Purchase Assurance Programs. Specifically, 18 residences declined voluntary participation in the Programs in writing. An additiona164 homeowners did not respond to any of the participation opportunities. TELEPHONE COMPLAINT CALLS (January 1, 2008 -March 31, 2008) 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 1, 2008 through March 31, 2008, the Office received 247 complaints from citizens. This is a 57.3% increase from the 157 complaints received last quarter. It is a 38.0% increase from the 179 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.

Hal Marshall discussed terminal gates and asked about the passenger cap at JWA. Eric Freed explained the passenger limits. Sarah Demont asked how the Access and Noise office handles the complaint line. Irma Ortega explained the complaint handling process. If requested, complaints are researched and follow-up calls are made. For all complaints an attempt is made to identify the aircraft that generated the complaint and the information is entered into the complaint database. Nancy Alston spoke of a conversation she had with Maria Pope of JWA's Environmental Division, regarding the Air Quality Management District (AQMD), and the lack of influence the AQMD has with the FAA. Nancy Alston provided two noise complaints from a resident. Irma Ortega said she would look into the complaints and call the resident with the fmdings. -16- NAC ROSTER March 12, 2008 NAME Greg Carroll Hal Marshall Homer Bludau Nancy Alston Joseph Deaton Sarah Demont Melinda Seely Eric Freed Irma Ortega Jim Sugden Silvia Zavala ORGANIZATION AirFair Foothill Community Association/ N.

Murphy Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 142nd 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 defming "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: 20162 S.W. Birch St., Newport Beach NMS-7S: 1131 Back Bay Drive, Newport Beach NMS-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-SS: 324 'h Vista Madera, 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 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, 2007 -June 30, 2008). 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 Figure 2 -3- AIRCRAFT TRAFFIC SUMMARY The Airport traffic summary for this quarter is shown in Table 1 and Figure 3 below. Air Carrier operational count histories and average daily departure counts are illustrated in Tables 9 & 11.

(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 General Aviation Jet aircraft are shown in Tables 6 through 8. For the twelve month period ending June 30, 2008, 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 dwelling si2sios _4_ units in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending March 31, 2008. Four hundred and eighteen residences in the Santa Ana Heights area have been sound attenuated and an avigation easement reserved through the County's Acoustical Insulation Program. The County has also acquired 46 residences as part of the Purchase Assurance Program, many of which were acoustically insulated, an avigation easement reserved and then resold. Among these County acquired homes, those located within areas designated for Business Park uses were razed, avigation easements were reserved, and the land resold for compatible Business Park uses. A total of 464 residences in the Santa Ana Heights area have been purchased or otherwise made compatible through the County's Purchase Assurance and Acoustical Insulation Programs. A number of residences also chose not to participate in the County's Acoustical Insulation and Purchase Assurance Programs. Specifically, 18 residences declined voluntary participation in the Programs in writing. An additional 64 homeowners did not respond to any of the participation opportunities. TELEPHONE COMPLAINT CALLS (April 1, 2008 -June 30, 2008) 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, 2008 through June 30, 2008, the Office received 400 complaints from citizens. This is a 61.9% increase from the 247 complaints received last quarter. It is a 16.3% increase from the 344 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.
