SCHINDLER, CITY MANAGER Agenda Item 8 Initial Reviewed: City Manager a� Finance Director N/A FROM: JUSTINA L. WILLKOM, COMMUNITY DEVELOPMENT DIRECTOR SUBJECT: JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORT — QUARTER THREE AND QUARTER FOUR, 2024 SUMMARY: This agenda report transmits the John Wayne Airport Noise Abatement Quarterly Report for the third and fourth quarters of 2024. The City of Tustin is within the John Wayne Airport's "Noise Impact Area" since it has the potential to be exposed to an average Community Noise Equivalent Level of more than 65 decibels. Community Noise Equivalent Level is a weighted average of noise levels over a 24-hour period, and is a measurement frequently used in regulating the impacts of airport noise on the surrounding community. The average noise levels measured at Tustin's monitoring station, which is located at Columbus Tustin Middle School on Beneta Way (site map provided as Attachment A), remained below the City, County, and State maximum criteria during the third and fourth quarter reporting periods. RECOMMENDATION: That the City Council receive and file this report. FISCAL IMPACT: There is no fiscal impact associated with this item. CORRELATION TO THE STRATEGIC PLAN: Staff's analysis and report of the quarterly John Wayne Airport 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. BACKGROUND AND DISCUSSION: Following the conclusion of each calendar quarter, John Wayne Airport (JWA) noise office staff prepares a Noise Abatement Program Quarterly Report and posts the report on their website. The JWA Noise Abatement Report includes measured noise levels, and an Docusign Envelope ID: C1 EA196D-5BA2-4ECD-9D59-E3EE3CFF8CE2 City Council Agenda Report John Wayne Airport Noise Report May 6, 2025 Page 2 analysis of noise complaints. Included as Attachments B and C to this report, are the quarterly reports for the third and fourth quarters of 2024, which includes the months of July through December 2024. 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 reporting periods within the last several years, as the air -travel throughout the region has continued to increase to pre -pandemic levels. During the third and fourth quarters of 2024, the average Community Noise Impact Level (CNEL) at Tustin's monitoring station on Beneta Way was 57.1 decibels (dB) during both quarters, while the averages from the previous two quarters (quarter one and two 2024) were 58.1 dB. Figures 1 and 2 provide a visualization of Tustin's CNEL levels for each month during the third and fourth quarters of 2024. 70 60 50 w 40 J J z 30 U 20 10 0 Daily Community Noise Equivalent Levels (CNEL) in Tustin: 03 July - Sept. 2024 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 Date Figure 1 July Au gu st September Noise Impact Area Level (65 dB) Docusign Envelope ID: C1 EA196D-5BA2-4ECD-9D59-E3EE3CFF8CE2 City Council Agenda Report John Wayne Airport Noise Report May 6, 2025 Page 3 70 60 50 w 40 J J z 30 U 20 10 0 Daily Community Noise Equivalent Levels (CNEL) in Tustin: Q4 October - December 2024 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 Date Noise Complaints Figure 2 October November -December Noise Impact Area Level (65 dB) The role of the John Wayne Airport (JWA) Access & Noise Office (ANO) is to enforce operational and noise restrictions. The ANO receives and investigates noise calls and complaints from local citizens and other sources. During the third quarter of 2024, there were 66 Tustin area concerns submitted, and during the fourth quarter of 2024 there were 58 concerns submitted. It should be noted that all complaints were submitted via the web or by pressing an alert button on the JWA mobile app. Further details from JWA staff indicates that during the third quarter there were four (4) individuals reporting concerns in total, and one (1) of the individuals submitted 59 of the 66 noise concerns. During the fourth quarter there were five (5) individuals reporting concerns in total, and one (1) of the individuals submitted 39 of the 58 noise concerns. Staff has reviewed the noise levels at Tustin's noise monitoring station during the time the concerns were submitted, and did not identify any unusual increase in the measured noise levels. Due to the release of the noise reporting mobile app and web -based platform (beginning in the second quarter of 2022), it is anticipated that a similar trend will continue, with a small number of reporting parties pressing an alert button repeatedly. Prior to the release of the mobile app and web platform, complainants would typically call JWA to report a noise concern, in which the data historically indicated that average of one (1) noise concern was submitted via phone call, per quarter.

Noise Standards Submitted by: Signed by: I r-,"us A1A526A921AF49F... Charlene V. Reynolds Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 2071" 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, 2023 - September 30, 2024). 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".

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 VWX entries in each table. Also, "*#N/A" entries in each table indicate contaminated data and/or no aircraft -related noise events. Average Single Event Noise Exposure Level (SENEL) values for Air Carrier and General Aviation Jet aircraft are shown in Tables 6 through 8. 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. Seventy-three dwelling units in Santa Ana Heights remain in the "Noise Impacted Area" (within 65 dB CNEL contour). COMPLAINT TOTALS (July 1, 2024 - September 30, 2024) The Airport's Access and Noise Office receives and investigates noise complaints (noise events) from local citizens and all other sources.

Mr. Gaskins informed attendees that Access and Noise Office ("ANO") Specialist, Mr. Kyle Gorny, will be presenting an update to the aircraft noise/altitude analysis at the upcoming Newport Beach Aviation Committee meeting in October. Lastly, Mr. Gaskins stated that it is the intent of the Airport to create an airport -managed operations/noise database on the Airport's website which would be accessible to the public. Newport Beach resident, Dr. Jim Mosher, inquired whether the new airport -managed database will be updated retroactively to where the City of Newport Beach's dashboard left off. Mr. Gaskins stated that he believed that the Airport could accommodate the request to backfill the database. A summary of the JWA August 2024 statistics and Airport's Q2 2024 Quarterly Noise Report ("QNR") were provided by ANO Specialists, Mr. Anthony Cangey and Ms. Beatrice Siercke. Mr. Gaskins presented updates on the Fly Friendly Program, new generation aircraft fleet mix, and Plan Year 2024/2025 capacity. Dr. Mosher inquired about the increase in general aviation ("GA") traffic reported in the August 2024 statistics report. Mr. Gaskins explained that the ANO is aware of an increase in general aviation operations and indicated that it could be related to an increase in traffic pattern activity at JWA resulting from operational restrictions at other local airports. Dr. Mosher inquired about Table 5 in the QNR and indicated that Noise Monitoring Stations ("NMS") 2, 4, 6, and 10 were offline for a period of approximately three days. Mr. Gaskins explained that a software issue was discovered that affected those four NMS locations. Dr. Mosher brought forth a second discrepancy in the QNR regarding the total number of Airbus A306 ("A306") aircraft operations. Dr. Mosher stated that based on his observation of the Detailed Noise Event Reports, the A306 does not appear to be the noisiest departure during Q2 2024. Mr. Gaskins notified Dr. Mosher that the ANO will review the QNR, and if necessary, make appropriate revisions. Mr. Jason Herman with Air Line Pilots Association, International, asked whether the projection of 11.2 Million Annual Passengers ("MAP") for Plan Year 2024 is the current projection. Mr. Gaskins explained that while this number is subject to change, 11.2 MAP is the current projection. 16 - Dr. Mosher requested clarification on the ANO's data retention policy. Mr. Gaskins explained that prior to the most recently approved County of Orange ("County") retention policy, the ANO archived data/reports dating back approximately 15-20 years. Mr. Gaskins stated that, however, based on the current retention policies set forth by the County, the Airport is adhering to the approved retention schedule. Dr. Mosher expressed concerns regarding whether the data would still be accessible to update the anticipated airport -managed database. Mr. Gaskins stated that the ANO will discuss these concerns with the Airport Director. Dr. Mosher also inquired what QNRs are available based on the County's retention policy. Mr. Gaskins explained that the current retention policy for QNR is four years plus the current calendar year. Dr. Mosher did explain that some records can be retrieved from the City of Tustin. Dr. Mosher expressed that historical data would be beneficial in calculating aircraft engine performance. Mr. Gaskins assured Dr. Mosher that his concerns will be presented to the Airport Director. Dr. Mosher inquired about the number of GA noise violations in Q1/Q2 2024. Dr. Mosher stated that it seems statistically unusual for no aircraft to reach a Denial of Use ("DOU") during the first six months of a year. Mr. Gaskins informed Dr. Mosher that is not unusual that the Airport could not have an operator receive a DOU in a six- month period. Mr. Gaskins explained that outreach, particularly Fly Friendly outreach, could effectively be reducing the total number of noise violations. Dr. Mosher asked how many aircraft are completely denied from the Airport and how many are denied only during GA "nighttime" hours. Dr. Mosher questioned why the Airport does not post the individual flight/aircraft information when a DOU has been issued. Dr. Mosher asked if the ANO is tracking violations by the aircraft tail number or by the pilot/operator of the aircraft. Mr. Gaskins explained violations are attributed to the aircraft and owner/operator of the aircraft. Mr. Ron Rubino, Newport Beach Aviation Committee Member, asked if the ANO could investigate the possibility of making an exception to the County's retention policy of the noise data to ensure that this data is preserved. Mr. Rubino recommended that historical data obtained by the ANO be retained indefinitely. In addition, Mr. Rubino suggested that any alterations to the policies regarding the retention of noise data should be discussed with all parties of the 1985 Settlement Agreement before adoption and implementation. Mr. Gaskins stated that he would meet with the Airport Director to discuss these requests. Mr. Rubino also sought confirmation that the Airport is not seeing a potential need to issue a reduction in commercial operations capacity for the 2024 or 2025 Plan Year. Mr. Gaskins confirmed that at this time, there are no indications of a need to reduce commercial operations capacity. Mr. Gaskins explained that this is the result of the Airport's conservative approach to allocating capacity for both the 2024 and 2025 Plan Years. Mr. Gaskins stated that a variety of factors play a role in the number of total passengers that travel through the Airport each year. Mr. Rubino expressed his satisfaction with the mitigation measures implemented by the ANO to remain in compliance with the 11.8 MAP. Mr. Rubino complimented the ANO and the work being done at the Airport. Mr. Rubino also expressed his satisfaction with the transparency of the ANO. Mr. Rubino went on to state that the data provided is accurate and reported on a consistent basis. Mr. Rubino did express concerns regarding NMS downtime and the lack of noise data available during these periods. Mr. Gaskins explained that recent changes in property ownership, ongoing construction, and NMS battery life have all been factors that have played a role in the recent operational capacity of the NMS sites. Mr. Gaskins informed Mr. Rubino that 20 new backup batteries were recently ordered for the NMS sites. Lastly, Mr. Gaskins stated that the Airport has actively been working with new property owners and contractors to ensure that the NMS sites always remain functional. Newport Beach resident, Mr. Joe August, stated he would like to see more action taken to prevent noise events from being disassociated from operations. Mr. August also suggested adding additional bird spikes to the NMS, or relocating the NMS away from the street. Mr. August inquired as to why dissociated noise data is not publicly available. Mr. Gaskins explained that the ANO is actively working with Supervisor Katrina Foley's Office to produce a report regarding the effect that disassociated noise events have on the overall monthly/quarterly noise averages.

Noise Standards Submitted by: ESigned by: �.i,12�,ywoCoCs A 1A526A921AF49F... Charlene V. Reynolds Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 208'h 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 (January 1, 2024 - December 31, 2024). The Figure 2 information was developed by Harris Miller Miller & 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".

Insufficient data is indicated by VWX entries in each table. Also, "*#N/A" entries in each table indicate contaminated data and/or no aircraft -related noise events. Average Single Event Noise Exposure Level (SENEL) values for Air Carrier and General Aviation Jet aircraft are shown in Tables 6 through 8. 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.

This resulted in the Quarterly Noise Report ("QNR") being posted the evening before the meeting. Access and Noise Specialists, Mr. Anthony Cangey and Ms. Beatrice Siercke provided an overview of the October 2024 airport statistics and the Q3 2024 QNR. Newport Beach resident, Dr. Jim Mosher, observed that while total passengers have declined, aircraft operations have increased. Mr. Gaskins explained that while aircraft load factors have declined, the number of aircraft operations has remained steady in comparison. Mr. Gaskins described the process by which airlines were offered the ability to return 2024 Plan Year operational capacity to minimize any potential issues with the 11.8 million annual passenger (MAP) limitation. Mr. Gaskins mentioned that the current projection of 11.2 MAP may be a result of these returns of operational capacity. Dr. Mosher notified the Access and Noise Office ("ANO") that the Frequently Asked Questions ("FAQ") on the Airport's Access and Noise webpage does not reflect recent updates to the long-term Community Noise Equivalent Level ("CNEL") trends. Mr. Gaskins thanked Dr. Mosher for his observation and explained that the Airport will update those values as soon as possible. Dr. Mosher explained that it appears the Noise Impact Area displayed in Figure 2 in the QNR is larger than the area outlined in the Q2 2024 QNR despite Table 2 indicating decreasing long-term measured CNEL levels when compared to the levels from the prior quarter. Mr. Gaskins explained that the Airport will address these concerns with the Airport's on -call acoustical engineering consultant, Harris Miller Miller & Hanson Inc., who prepared the CNEL contour. Mr. Gaskins informed the attendees that the Airport will present the second part of the Newport Beach altitude/noise analysis at the scheduled January Newport Beach Aviation Committee meeting. Newport Beach Aviation Committee member, Mr. Jack Stranberg, inquired why Airport passenger traffic is down at JWA. Mr. Gaskins expressed that this is the result of a few variables. Mr. Gaskins mentioned that due to the voluntary capacity returns offered to carriers for the 2024 Plan Year at JWA, as well as possible lower fares at nearby airports, which may have resulted in some travelers possibly utilizing those airports, load factor and passenger traffic had decreased. Mission Viejo resident, Ms. Barbara McMullen, highlighted her concerns over perceived increases in aircraft activity near her residence. Ms. McMullen mentioned that this activity included training aircraft performing maneuvers which appeared to be unsafe. Mr. Gaskins informed Ms. McMullen of the close proximity of a designated training area near the city of Mission Viejo. Mr. Gaskins informed Ms. McMullen that additional information would be provided to her after the meeting in a follow-up email. Mr. Stranberg also commented that the concerns by Ms. McMullen regarding such maneuvers, may allude to a safety issue that could be investigated by the Federal Aviation Administration ("FAA"). Mr. Gaskins responded by ensuring Ms. McMullen that the appropriate FAA contact information will be provided so that she can address these concerns with the appropriate division within the agency. Dr. Mosher also commented on Ms. McMullen's concerns by indicating that the most recent QNR reflects an increase in general aviation ("GA") operations, while GA jet operations have decreased, implying a potential increase in GA propellor aircraft operations. Mr. Gaskins explained that one possible factor contributing to the increase in GA propeller aircraft operations includes policies implemented at other airports, such as Torrance, that have resulted in more aircraft operators choosing to utilize JWA. Mr. Gaskins also explained that Runway 20L, which facilitates most propellor aircraft operations at JWA, was formerly open intermittently due to staffing constraints in the FAA's Air Traffic Control Tower ("ATCT"). Mr. Gaskins added that the staffing constraints in the ATCT were resolved and Runway 20L has been open daily for the last several months. Dr. Mosher asked if there were any updates to the outstanding questions from the prior quarterly meeting surrounding the County of Orange record retention policy and its application to the aircraft noise data retained by the Airport. Mr. Gaskins explained that this item has been discussed internally and will be followed up with the Airport Director. Dr. Mosher also expressed his interest in the altitude/noise analysis presentation that will occur at the Newport Beach Aviation Committee meeting in January and expressed the importance of aircraft weight when analyzing altitude. Mr. Gaskins informed Dr. Mosher that the upcoming presentation will include aircraft weight data within its research parameters.
