The average noise level measured at Tustin's monitoring station (NMS 1 ON), located at Columbus Tustin Middle School on Beneta Way (Figure 1), remained consistent with prior quarters. Average daily noise levels during the third quarter continued to remain well below the City, County, and State criteria of 65 decibels (dB) Community Noise Equivalent Level (CNEL)for residential uses. Residential noise sensitive areas exposed to an average Community Noise Equivalent Level (CNEL) of more than 65 dB define the "Noise Impact Area." RECOMMENDATION: That the City Council receive and file this report. FISCAL IMPACT: No fiscal impact. c • A r Figure 1 DocuSign Envelope ID: BEEAB75A-8508-4310-BF6D-8D90EB180C2B JWA Noise Report February 1, 2022 Page 2 CORRELATION TO THE STRATEGIC PLAN: Staff's analysis and report of the quarterly JWA Noise Abatement Report falls under Goal D of the Strategic Plan pertaining to strong community and regional relationships. The City of Tustin strives to work collaboratively with agencies both within and outside Tustin on issues of mutual interest and concern, and in this instance, on matters of airport traffic and noise. DISCUSSION: Following the conclusion of each calendar quarter, JWA staff prepares a Noise Abatement Program Quarterly Report and posts the report on their website. Attached is the quarterly report for the third quarter of 2021, which includes the months of July through September 2021 . The JWA Noise Abatement Report includes measured noise levels and an analysis of noise complaints. Measured Noise Levels Aircraft noise is most noticeable during airplane takeoffs and landings, primarily due to engine noise. Although engines produce a significant amount of aircraft noise, many other factors may influence the perception of noise including: proximity; weather — in bad weather, engine noise is reflected off of the atmosphere making jets appear louder than on clear days; routes — non-scheduled operations which could include military or private aircraft and may be louder than commercial aircraft; emergencies; and, weight—a heavier load may affect an aircraft's rate of ascent. In addition, higher aircraft noise level measurements may have been noted during recent reporting periods, as the air-travel throughout the region has begun to increase to pre-pandemic levels at 65% - 70% of the 2019 passenger levels. During the third quarter of 2021, the average CNEL at Tustin's monitoring station on Beneta Way was 57.1 dB while the average from the previous quarter was 56.4 dB. The average noise levels remained well below the City, County, and State criteria of 65 dB CNEL for residential uses. Figure 2 (below) provides a visualization of Tustin's CNEL levels for each month during the third quarter of 2021 .

The ANO receives and investigates noise calls and complaints from local citizens and other sources. During the third quarter of 2021 , there were zero (0) Tustin area concerns submitted. City staff recently discovered that noise report data from North Tustin (92705 zip code) which is a County of Orange/unincorporated area, was mistakenly being recorded as noise concerns reported within the City of Tustin. Staff has outreached to the Access and Noise Office for updated data, and has retrospectively modified the noise complaint data to include noise concerns reported by City of Tustin residents, only. To provide an understanding of the trend in Tustin area complaints throughout the years, a chart displaying the number of noise complaints for the past three (3) years is displayed in Figure 3 (below).

WebTrak is a web-based flight tracking system that shows flights around the airport. It is integrated with JWA's noise monitoring system to show noise levels at each monitoring station and allows the public to easily submit noise event information. CONCLUSION: Since noise issues are of considerable importance to the City of Tustin, the Community Development Department will continue to monitor operations at JWA. The public is additionally welcome to participate in JWA's Quarterly meetings held by the Access and Noise Office. The next quarterly meeting will be held on March 22, 2022, at 2:00 p.m. in the Eddie Martin Administration Building located at 3160 Airway Avenue in Costa Mesa. Staff recommends that the City Council receive and file this report.

Noise Standards bmitted by: Rick Fr ncis Interim Airport Director John Wayne Airport, Orange County DocuSign Envelope ID: BEEAB75A-8508-4310-BF6D-8D90EB180C2B JOHN WAYNE AIRPORT Noise Abatement Program ORANGE COUNTY Quarterly Report July— September 2021 INTRODUCTION This is the 195th Quarterly Report submitted by the County of Orange in accordance with the requirements of the California Airport Noise Standards (California Code of Regulations, Title 21: Public Works, Division 2.5, Division of Aeronautics (Department of Transportation), Chapter 6. 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-2S: 20162 S.W. Birch St., Newport Beach NMS-3S: 2139 Anniversary Lane, Newport Beach NMS-4S: 2338 Tustin Ave., Newport Beach NMS-5S: 324 '/2 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-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 (October 1, 2020 - September 30, 2021). The Figure 2 information was developed by Harris Miller Miller and Hanson 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".

ACOUSTICAL INSULATION PROGRAM Four hundred eighteen residences in the Santa Ana Heights area have been sound attenuated and an avigation easement reserved through the County's Acoustical Insulation Program, which closed in December 2009. 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. Three dwelling units in Santa Ana Heights remain in the "Noise Impacted Area" (within 65 dB CNEL contour). COMPLAINT TOTALS (July 1, 2021 - September 30, 2021) The Airport's Access and Noise Office receives and investigates noise complaints from local citizens and all other sources. During the period of July 1, 2021 through September 30, 2021, the Office received 63,128 complaints from local citizens. This is a 10.4% increase from the 57,197 complaints received last quarter.

He mentioned that the Access & Noise Office has been working on the allocations since August, with the ASR going to the Airport Commission on October 20 and to the Board of Supervisors on November 2. Mr. Gaskins also added that next year the Access & Noise Office is planning to start the capacity allocation process earlier for Plan Year 2023. Mr. Gaskins advised that the 2nd Quarter Noise Report is currently available on the JWA website and acknowledged that technical issues contributed to the delayed posting. Mr. Gaskins also explained that there were edits to the 1 st Quarter Noise Report, and the revised report will be posted to the JWA website within the next couple of days. Mr. Gaskins mentioned that the Access & Noise Office is adding a new Specialist on October 8. Mr. Gaskins explained that the new Specialist is filling a vacancy that had been open since April 2020. Mr. Gaskins gave an update on commercial airline service. He stated Air Canada is starting their new international service to Vancouver on October 2, operating the A220-300 aircraft type. Mr. Gaskins also added that WestJet is resuming its service to Vancouver on October 1. Mr. Gaskins discussed that Allegiant Air is introducing service to new markets out of JWA that include: Sioux Falls Regional Airport (FSD), Phoenix-Mesa Gateway Airport (AZA), Eugene Airport (EUG), and Austin-Bergstrom International Airport (AUS). Mr. Gaskins added that United Airlines will be adding seasonal service to Aspen/Pitkin County Airport (ASE) from December 16, 2021, through March 26, 2022. Cristina Magana provided a summary of the JWA airport statistics for July 2021. She stated there was a 272.3% increase in passenger volume compared to July 2020. Ms. Magana also added that JWA increased 35% in aircraft operations, 25.4% in general aviation operations, and 85.9% in commercial operations compared to July 2020. Mr. Gaskins conducted a presentation on WebTrak, the new flight tracking system available to the public on the JWA website. Mr. Gaskins explained why the Airport transitioned from VOLANS to the WebTrak flight tracking system, and he gave a brief tutorial highlighting some of the critical features of the new system. Newport Beach resident Joe August asked if there was any initiation from the Airport or County requesting Air Canada to fly quieter aircraft, or was it solely the airline's decision. Mr. Gaskins explained that the Access & Noise Office had been in discussions with Air Canada about what types of aircraft they were plan on using. But, it's the carrier's decision which aircraft they operate at each Airport based on their delivery schedule and network planning. DocuSign Envelope ID: BEEAB75A-8508-4310-BF6D-8D90EB180C2B JOHN WAYNE AIRPORT Noise Abatement Program ORANGE COUNTY Quarterly Report July— September 2021 QUARTERLY NOISE MEETING Newport Beach resident Dr. Jim Mosher asked why the historical data on WebTrak is limited to three months. Mr. Gaskins was unsure of the reasoning and would contact EVS to see if three months is the standard. Dr. Mosher also expressed his concerns with a possible technical glitch with WebTrak when the SENEL noise values switch from a circle shape to a square shape when the noise level exceeds 65 dB. He also described an issue with the playback mode where the values are not consistent at each exact second. Mr. Gaskins asked Dr. Mosher to provide examples, and our office will forward them to EVS for further explanation and analysis. Dr. Mosher stated there was an issue with the image of the recent Quarterly Noise Report that was on the JWA website, and if Figure 2 was the annual or quarterly contour. Mr. Gaskins explained there was an issue with the network drive and the report will be replaced with the corrected image as soon as the network drive issue is resolved. Mr. Gaskins also explained that Figure 2 is the twelve-month contour, which includes 2nd Quarter, and that the annual contour is exclusively in the 4t" Quarter Noise Report. Dr. Mosher asked if Table 8 of the Quarterly Noise Report represents both commuter and charter flights for Delux Public Charters (JSX) and if the noise office can distinguish between the two. Mr. Gaskins explained Table 8 represents JSX's commuter operations; not charter operations, and confirmed the JWA Access & Noise Office has the ability to determine the difference between commuter and charter operations for JSX by reviewing the flight information in ANOMS and Access/GANG. Dr. Mosher also wanted to know if there was a difference between the SkyWest E175 and SkyWest E75L aircraft types and if the two aircraft types could be combined together in the Detailed Noise Reports. Mr. Gaskins confirmed the two aircraft types are the same, and the two separate codes are a result of how they are labeled in ANOMS. Mr. Gaskins also added the two can probably be combined into the E175, but it could create a delay with getting the Detailed Noise Reports posted on the JWA website.
