NO. 6 08-07-00 _ Inter-Com DATE' AUGUST 7, 2000 TO: FROM: SUBJECT: WILLIAM A. HUSTON, CITY MANAGER COMMUNITY DEVELOPMENT DEPARTMENT JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORTS SUMMARY: This report transmits two John Wayne Airport Noise Abatement Quarterly Reports for the third and fourth quarters of 1999. The average noise level measured at monitoring station NMS 10N (formerly M-7), located at Columbus Tustin Middle School, slightly increased during the third quarter and decreased during the fourth quarter. 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 Receive and file report. FISCAL IMPACT The City retains the acoustics consulting fn-m of J.J. Van Houten and Associates, Inc. to review JWA Noise Abatement Quarterly Reports. The costs for such reviews are annually included in the Community Development Department budget. 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. Twice a year, the City's consultant prepares a report, which summarizes two quarterly reports. Exhibit A contains the quarterly reports for the third and fourth quarters of 1999. Exhibit B contains the summary report prepared by the noise consultant. A brief overview of the information contained within these attachments follows. Measured Noise Levels During the third quarter of 1999, the average CNEL at Remote Monitoring Station (NMS) 1 ON (formerly RMS #7), located at Columbus Tustin Middle School was 57.4 dB. This is .5 dB more than the four previous quarters. However, for comparison, the CNEL was 1.1 dB lower (56.3) during the third quarter of 1998. City Council Report .IWA Noise Abatement Ouarlc~,: J<eports August 7, 2000 Page 2 During the fourth quarter of 1999, the average CNEL was 56.0 dB. This is 1.1 dB more than the four previous quarters. For comparison, the CNEL was 1.2 dB higher (57.2) during the fourth quarter of 1998. All measured noise levels are below the City, County and State criteria of 65 dB CNEL for residential areas. Noise Complaints During the third quarter of 1999, there were 57 Tustin/Orange complaints compared with 79 for the same period during 1998. During the fourth quarter of 1999, there were 18 Tustin/Orange complaints compared with 32 for the same period during 1998. The number of complaints decreased during the third and fourth quarters compared to the same period in 1998. The overall number of complaints during the last two quarters of 1999 appears to correlate with the average quarterly aircraft CNEL but not with the number of quarterly jet operations at the airport. The number of jet operations increased steadily throughout 1999, but the number of complaints peaked in the third quarter and dropped significantly in the fourth quarter. Type and Mix of Aircraft Related to Noise Levels During the third quarter of 1999, the percentage of quieter Class E aircraft increased and the percentage of noisier Class A aircraft decreased compared with the same period in 1998. The average CNEL for the third quarter of 1999 was slightly higher than 'the same period during 1998. During the fourth quarter of 1999 the percentage of quieter Class E aircraft increased and the percentage of noisier Class A aircraft decreased compared with the same period in 1998. The average CNEL for the fourth quarter was slightly lower than the fourth quarter of 1998. The percentage of quieter Class E aircraft using John Wayne Airport has increased slightly in 1999, compared to 1998. This percentage increase in Class E aircraft was offset by a decrease in the use of the noisier Class A and Class AA aircraft. Based on data fi.om first quarter of 1998. through the fourth quarter of 1999, there does not appear to be any correlation between the aircraft mix and the average quarterly CNEL at NMS 10. Airport Noise Contours A noise contour was utilized by Van Houten and Associates, Inc. in preparing the attached report. This noise contour is based on the 1998 contours developed by the noise consultant for the John Wayne Airport Noise Abatement office. Using this new contour, it is estimated that in 1999 the aircraft-generated CNEL in Tustin will range from about 60 dB to less than 55 dB. This is well below the City, County and State criteria of 65 dB for residential areas.

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 SU31MARY 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 monitoring stations (NMS) located in Newport Beach, Santa Ana, Tustin and Irvine to measure noise levels. Effective July 1, 1999, the numbers used to refer to the remote monitoring stations were changed. In the new numbering scheme, the letters "S" and "N" refer to the monitoring stations' location either to the south or to the north of the airport. The numbering and location of each monitor is as follows: Former NMS Number MONITOR STATIONS New NMS Number Location 1 1S 2 2S 3 3S 22 4S 21 5S 24 6S 6 7S 9 8N 8 9N 7 10N Golf Course, 3100 Irvine Ave., Newport Beach 20152 S.W.

Figure 2 shows the Airport's "Noise Impact Area" for the previous year (October 1, 1998 - September 30, 1999). 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 I JOI-..,i STATION !

COMMUNITY NOISE Eq}UIV.M.~ENT 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 Carder and Business Jet aircraft are shown in Tables 6 through 8. -4- For the twelve month period ending September 30, 1999, 105 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents an decrease of two units in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending June 30, 1999. 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 Ana Heights Acoustical Insulation Program" with the acronym "SAH AIP".) During the third quarter of 1999, no additional residences have been made compatible through the County's SAH AIP. A total of 224 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 (July 1.1999 - September 30, 1999) 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, 1999 through September 30, 1999, the Office received 684 complaints from citizens. This is a 98.3% increase from the 345 complaints received last quarter. It is a 3.0% decrease from the 705 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.

Replacement Monitoring System Update John Leyefle announced that on August 31, 1999, the Airport Director signed the letter of acceptance for the replacement monitoring system. This new system replaces our previous noise monitoring system which had been in place since 1979. In January 1997, the Board of Supervisors awarded the contract for the development and installation of the new system to Tracor Applied Sciences, Inc. (now BAE Systems North America) of Austin, Texas. With the completion of this contract the JWA Airport Access and Noise office now has a state-of-the-art aircraft operations and noise monitoring system which will allow us to better serve our customer groups, which include the community and the air carriers. 2. Airport Operation Statistics for August 1999 Bonnie Streeter gave an update on the August statistics. For the first time in this calendar year, our statistics show an increase in the number of passengers served during a month over the number served in the same month in the previous year. Other monthly figures that show increases over Au~oz~st 1998 levels were total operations, general aviation operations and air- cartier operations. There were decreases in air cargo tonnage, air taxi and military operations. 3. Status of the Santa Ana Heights Acoustical Insulation Program Ann Gill of JWA gave an update. There are currently several series or groups of homes which are in various stages of construction. One group of twenty-two homes has been completed and is awaiting approval fi.om the building department. Construction began on another group of twenty-one homes during the tn-st part of August. A contract for the next group of twenty-two homes was awarded at the end of July and the construction materials have been ordered. Specifications are being completed now on an 182-unit apartment building; the contract for this series will be opened for competitive bid within the next two months. Thirty-three more homes are in the engineering phase, with construction expected to begin in approximately one year. -16- Noise Abatement Committee Meeting Continued Recently, the JWA Santa Ana Heights Acoustical Insulation Program (SAIl AIP) received a visit from officials at San Diego International Airport. The San Diego officials are about to initiate a program to acoustically insulate about 12,000 homes within their noise impact area and were interested in learning about our methods of managing the SAH AlP. They videotaped their tour, which was conducted by Carl Braatz, the SAH AlP Project Manager: Q. Bernard Burger asked, "How far does the [JWA] program extend geographically?" A. John Leyerle replied that the 65 dB CNEL contour which defines the area of the project extends a little less than a mile from the south end of the main departure runway (19R). Q. Kevin Chun asked "What is the average cost per home [for acoustical insulation]?" A. John Leyerle explained that the Board of Supervisors has set a limit of $38,500 per home. However, recent changes in the bidding process have brought down the average cost while keeping quality high. The average cost per home since these changes were instituted is in the mid-S20,000 range. 4. Additional Questions Q. Bernard Burger explained that his home is located about ten miles from the airport. He noted that during instrument flight conditions he experiences less noise and less overflights than during times when visual flight roles are in effect. He asked why this was the case. He stated that he often experiences very low flying aircraft over his home and that the noise is often loud enough to interrupt conversation. A. John Leyerle stated that the Federal Aviation Administration (FAA) and the Pilot-in Command (PIC) have jurisdiction of aircraft in flight. He described the two principle routes utilized by the FAA and the PIC on approach to JWA. The difference between Instrument Flight Rules (IFR) and Visual Flight Rules (VFR) was explained along with the way the F.4A~ handles arrivals during each of these conditions. The telephone number of the FAA's Western Regional Office and the Flight Standards District Office were offered to Mr. Burger. John explained the difference between Single Event Noise Event Exposure Level (SENEL) and Community Noise Equivalent Level (CNEL). The CNEL unit of measure is the standard which has been adopted by the Federal, state and local government for use in identifying noise exposures for land use compatibility determination. -17- Noise Abatement Committee Meeting Continued Q. Mark Esslinger asked "What is the current CNEL in [the North Tustin] area?" A. John Leyerle answered that the current CNEL is in the mid-50 decibels. Q. Toni Callaway inquired about a 1995 EIR produced by the FAA regarding an altered approach path over her area. She expressed concern about aircraft flying too low over her area. She further stated that she still is not receiving return calls from the Access and Noise Office in response to her calls. She asked what was going to be done with the noise monitoring stations from our old system, suggesting that they should be placed in areas that are experiencing noise problems. A. John Leyerle briefly explained the FAA's 1995 study. He reasserted the commitment of the Access and Noise office to return the telephone calls of everyone who requests it, and who leaves a return telephone number. As to the status of the old noise monitoring stations, John explained that they are not Y2K compliant and therefore would not be functional after December 31, 1999. 5. Next Meeting Date The date for the next quarterly Noise Abatement Committee meeting will be announced by letter approximately two weeks prior to the meeting. -18- NAC ROSTER September 16, 1999 NAM2E ORGANIZATION Toni Marie Callaway Residents of North Tustin Bernard Burger Orange Park Acres Kevin Chun City of Irvine Mark Esslinger Travis Christ County of Orange Planning Department America West Airlines Paul Seifert Continental Airlines Ravin Agarwal Continental Airlines Ann Gill Loft Peters JWA GovemmentJCommunity Relations United Airlines Fred Pena Alaska Airlines -19- NOISE ABATEMENT PROGRAM QUARTERLY REPORT For the period: October 1, 1999 through December 31, 1999 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: John Wayne Airport, Orange County INTRODUCTION This is the 108th 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 (NMSs) located in Newport Beach, Santa Ana, Tustin and Irvine to measure noise levels. Effective July 1, 1999, the numbers used to refer to the remote noise monitoring stations were changed. In the new numbering scheme, the letters "S" and "N" refer to the monitoring stations' location either to the south or to the north of the airport. The numbering and location of each monitor is as follows: Former NMS Number MONITOR STATIONS New NrMS Number Location 1 1S 2 2S 3 3S 22 4S 21 5S 24 6S 6 7S 9 8N 8 9N 7 10N Golf Course, 3100 Irvine Ave., Newport Beach. 20152 S.W.

Figure 2 shows the Airport's "Noise Impact Area" for the previous year (January 1, 1999 - December 31, 1999). The Figure 2 information was developed by Mestre-Greve Associates, Inc., in consultation with John Wayne .Mrport. 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 JO, .,q WAYNE AiI-..~ORT STATION LOCATION MAP JOHN WAYNE 3RT E NMS - NOISE MONITORING STATION -2- 0 Noise Monitors Single Family Residential 65 dB CNEL Contour ~ Multi-Family Residential STATISITICS: Incompatible Land Use Area: 20.78 Acres or .032 square milesj Number of Dwellings: 119 Number of People: 298 (based on 2.5 people per dwelling unit) JOHN WAYNE AIRPORT 65dB CNEL Impact Area January 1999 - December 1999 Mestre ~re~e -~- 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 December 31, 1999, 119 dwelling units in Santa Ana Heights were in the "Noise Impacted Area" (within the 65 dB CNEL contour); this represents an increase of 14 units in the number of dwelling units in the "Noise Impacted Area" from the previous twelve month period ending September 30, 1999. 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 AIP".) During the fourth quarter of 1999, an additional 22 residences have been made compatible through the County's SAH AIP. A total of 246 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 (October 1, 1999 - December 31, 1999) 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, 1999 through December 31, 1999, the Office received 358 complaints from citizens. This is a 47.7% decrease from the 684 complaints received last quarter. It is a 18.9% increase from the 301 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls and complaints from local communities.

CA 92869 9491476-0932 FAX 949/476-1023 Dear Ms. Binsack, As requested, we have reviewed the referenced quarterly reports for the noise abatement program at John Wayne Airport. Please note that, effective July 1, 1999, the noise monitoring station (NMS) at 17952 Beneta Way in Tustin was renumbered to NMS 1 ON. The following provides our findings with regard to airport operations and their impact on the City of Tustin: . . Referring to Figures 1 and 2, the average annual CNEL at NMS 1 ON was 56.8 dB for 1999 based upon data for all four quarters. This is 0.2 dB lower than the average annual CNEL of 57.0 dB for 1998. (NOTE: The noise contours for John Wayne Airport are based on average annual CNEL values measured at each remote monitoring station.) The average annual CNEL of 56.8 dB in 1999 reflects the possible stabilizing of a modest upward trend in the aircraft noise exposure measured at NMS 1 ON. This trend is illustrated in the following table: CITY OF T[JSTIN ['reject }:Jlc 2779-98 Year Average Annual CNEL 1994 56.1 dB 1995 56.4 dB 1996 56.8 dB 1997 55.9 dB 1998 57.0 dB 1999 56.8 dB o Referring to Figure 2, the number of noise complaints received from the Tustin area in 1999 appears to correlate with the average quarterly aircraft CNEL measured at NMS 1 ON, but not with the number of quarterly jet operations at the airport. As indicated in the figure, the number of jet operations increased steadily throughout 1999, but the number of complaints peaked in the third quarter and dropped significantly in the fourth quarter. o As indicated in Item 1, above, the annual average CNEL measured at NMS 1 ON was 56.8 dB in 1999. This is slightly less than the 58 dB that was estimated for the station in the referenced aircraft noise impact study for the Phase 2 Access Plan (Reference 1). AIRCRAFT NOISE CONTOURS Figure 3 provides the estimated location of the John Wayne Airport noise contours for 1999. These are based on the 1998 contours developed by the John Wayne Airport Noise Abatement Office, and on data through the fourth quarter of 1999. Referring to Figure 3, it is estimated that in 1999 the aircraft-generated CNEL will range from about 60 dB to less than 55 dB. This is well below the City, County, and State criteria of 65 dB for residential areas. USE OF QUIETER AIRCRAFT AT JWA The correlation between the increasing use of quieter aircraft at JWA and the change in CNEL within the City of Tustin has been assessed. The Federal Aviation Administration (FAA) classifies aircraft into three categories based on noise levels. In order of decreasing noise levels, there are Stage I, Stage II, and Stage III aircraft. John Wayne Airport has only permitted Stage III aircraft since the early 1970' s. The airport has its own classification scheme for passenger aircraft. In order of decreasing noise level, these are Class A, Class AA, and Class E aircraft. Table 1 provides the estimated number of each class of aircraft that used the airport between the first quarter of 1998 and the fourth quarter of 1999. Also provided is the measured average quarterly CNEL at NMS 1 ON. Table 2 provides the same information, but the values have been normalized to 17,000 aircraft operations (takeoffs and landings) per quarter. In this way, a correlation can be established between the quarterly CNEL and the mix of aircraft types. Referring to Table 2 and Figure 4, the percentage of quieter Class E aircraft using John Wayne Airport has increased slightly in 1999, compared with 1998. This increase in Class E aircraft was offset by a decrease in the use of the noisier Class A and Class AA aircraft. Based on data from J. J. Van Houten & Associates, Inc. CITY 0t' TtJ.$'I'IN l'rojcc! Filc 2779-98 the first quarter of 1998 through the fourth quarter of 1999, there does not appear to be any correlation between the aircraft mix and the average quarterly CNEL at NMS 1 ON.
