WEST, CITY MANAGER FROM: COMMUNITY DEVELOPMENT DEPARTMENT SUBJECT: JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORT SUMMARY: This agenda report transmits the John Wayne Airport (JWA) Noise Abatement Quarterly Report for the first and second quarters of 2023. The City of Tustin is within the JWA’s “Noise Impact Area” since it has the potential to be exposed to an average Community Noise Equivalent Level (CNEL) of more than 65 decibels (dB). CNEL 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 level measured at Tustin’s monitoring station (NMS 10N), which is located at Columbus Tustin Middle School on Beneta Way (Figure 1), remained below the City, County, and State maximum criteria of 65 dB CNEL during the first and second quarter reporting period. RECOMMENDATION: That the City Council receive and file this report. FISCAL IMPACT: No fiscal impact.

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. The JWA Noise Abatement Report includes measured noise levels, and an analysis of noise complaints. Attached are the quarterly reports for the first and second quarters of 2023, which includes the months of January through June 2023. How Noise Levels Are Measured Both the Tustin General Plan and the John Wayne Airport Environs Land Use Plan (AELUP) utilize “Community Noise Equivalent Level” (CNEL) as the methodology for measuring noise impacts on airport adjacent land uses. For residential uses, the maximum acceptable outdoor CNEL is 65 decibels (dB). The 65 CNEL threshold is specified in the Tustin General Plan, the AELUP, and Titles 21 and 25 of the California Code of Regulations. The City’s General Plan defines CNEL as follows: “The average equivalent sound level during a 24 -hour day, obtained after the addition of five (5) decibels to sound levels in the evening from 7 p.m. to 10 p.m., and after the addition of ten (10) decibels to sound levels in the night after 10 p.m. and before 7 a.m.” The impact of aircraft noise on residential neighborhoods is therefore determined by evaluating the average hourly noise level experienced over a 24-hour period, with a weighted average of five (5) additional decibels applied in the evening, and ten (10) additional decibels applied at night. 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 lo uder 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.

Figure 2 (below) provides a visualization of Tustin’s CNEL levels for each month during the first and second quarters of 2023. Noise Complaints 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 first quarter of 2023, there were 531 Tustin area concerns submitted, and during the second quarter of 2023 there were 445 submitted. It should be noted that all of the 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 first quarter there were five (5) individuals reporting concerns in total, and one (1) of the individuals submitted 513 of the 531 noise concerns. During the second quarter there were four (4) individuals reporting concerns in total, and one (1) of the individuals submitted 437 of the 445 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 in 2022, it is anticipated that a similar trend will continue, with a small number of reporting parties pressing an alert button a significant number of times. Prior to the release of the mobile app, 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 per quarter. To provide an understanding of the trend in Tustin area complaints throughout the years, a chart displaying the number of noise complaints in the past three (3) years is displayed in Figure 3 (below).

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 ½ 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 (April 1, 2022 - March 31, 2023). 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".

Insufficient data is indicated by "#N/A" entries in each table. Also, "*#N/A" entries in each table indicate there were 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-one dwelling units in Santa Ana Heights remain in the "Noise Impacted Area" (within 65 dB CNEL contour). COMPLAINT TOTALS (January 1, 2023 - March 31, 2023) The Airport's Access and Noise Office receives and investigates noise complaints (noise events) from local citizens and all other sources. Figures 3.1, 3.2, and 3.3 illustrate the distribution of reported noise events from local communities, the nature of disturbance, and the method of how the noise events were reported to the Airport.

Ms. Siercke also provided a general overview of the Airport's Quarterly Noise Report for Q4 2022. Newport Beach resident, Mr. Dennis Bress, asked if noise increased or decreased when comparing Q4 2022 to Q3 2022 values. Mr. Nikolas Gaskins, Access and Noise Manager, replied that the Long Term Measured Levels on Page 6 of the report indicate a slight increase at some noise monitoring stations (NMS) when comparing the two quarters. Newport Beach resident, Dr. Jim Mosher, asked if there was a reason NMS 3S and NMS 9N were not functioning for several days in December. Mr. Gaskins explained that JWA's current contract for the noise monitoring system provides one spare microphone (mic). Mr. Gaskins added that the spare is utilized when a mic goes down, and the broken mic is sent to Denmark for repairs. Mr. Gaskins went on to say that two NMS locations went down during December, so the spare mic was used at NMS 3S, and the mic at NMS 9N was used to replace the nonfunctioning mic at NMS 8N since the daily generated noise levels at NMS 9N is limited. Mr. Gaskins mentioned the Airport's current mic is no longer manufactured and sold by the vendor. Still, the Airport obtained three additional mics from other airports, in the rare case multiple mics malfunction simultaneously in the future. When asked by Dr. Mosher about reciprocity between the new and old mics, Mr. Gaskins explained that side-by-side noise testing of NMS locations in 2015 was a result of the Airport installing an entirely new airport noise monitoring system, whereas, currently, the Airport had replaced two mics that are the same model as original mics. Dr. Mosher asked about the timeliness of providing the January 2023 and February 2023 Airport statistics to the public and the cause of the delay. Mr. Gaskins explained several factors, including the two NMS locations being inoperable for an extended time and an issue with the Federal Aviation Administration's (FAA) radar data that resulted in a delay for the ANO. Mr. Gaskins mentioned that the Fly Friendly Program data on the Airport's website shows January 2022 through November 2022. Mr. Gaskins stated that the Airport was awaiting direction from Fifth District on the announcement of 2022 Fly Friendly Program winners before publishing December 2022 Fly Friendly data. Mr. Bress asked if the JWA Quarterly Report was in compliance. Mr. Gaskins confirmed the report was in compliance. Mr. Bress said he did not see the "excluded noise events" in the report and wanted to know the total number of noise events not included in the Quarterly Noise Report. Mr. Gaskins stated the State of California does not mandate it. Mr. Gaskins added that the ANO had brought Mr. Bress’ request to JWA's Executive Management. Mr. Bress expressed that the JWA Quarterly Report is inaccurate because it does not contain "all" noise events and affects FAA's decision on noise abatement departure procedures at JWA. Mr. Gaskins reiterated that the FAA and the State of California have standards for reporting, and JWA abides by those standards. Mr. Bress disagreed that JWA was compliant and suggested the ANO be audited.

Mr. August stated he could send our office screenshots to show NMS 5S is registering at 35 dB while other NMS along the departure corridor are registering in the mid-40 dB range. Mr. August is concerned that this issue could affect the 24-hour Community Noise Equivalent Level (CNEL) average at NMS 5S. Mr. Gaskins stated the ANO was unaware of any issue and requested Mr. August send his information to the ANO. Mr. Gaskins discussed the aircraft noise qualification test for Breeze Airway's (Breeze) Airbus A220-300 for Class A operations. In addition, Mr. Gaskins added that Breeze recently completed a successful noise test for the Embraer E195 for Class A operations and are waiting for further analysis to determine an administrative qualification for Class E operations. Mr. Gaskins informed the group that JWA will begin the Airport's annual capacity allocation process for Plan Year 2024 on April 7, 2023, with an Airport Commission date in June and a tentative Board date in July. Mr. Gaskins emphasized that we are beginning the process early this year to give the ANO and airlines more time to work through requests and address any issues that may arise. Mr. Gaskins mentioned that the Airport submitted the Fly Friendly Report final draft to Fifth District and plans to meet with Supervisor Foley later this month to address any questions she might have regarding the report. When asked by Dr. Mosher when Breeze conducted their aircraft noise test for the E195, Mr. Gaskins stated it was on March 13, 2023. Dr. Mosher assumed any high noise readings for the Breeze A223 noise test were due to being fully loaded. Dr. Mosher asked how Breeze tends to operate the A223 as Class E. Mr. Gaskins explained Breeze's noise test was conducted at maximum projected gross takeoff weight (GTOW) for their long-haul routes. However, Breeze's GTOW for short-haul flights is comparable to the Delta Air Lines’ A223 aircraft with similar GTOWs. Dr. Mosher asked if the Airport receives GTOW data for general aviation (GA) jets. Mr. Gaskins stated we do not receive GA GTOW data. Dr. Mosher also asked if the GA GTOW data is reported to the FAA. Mr. Gaskins noted that the Fixed Base Operators (FBO) might have that information but could not confirm if GA GTOW data was reported to the FAA. Dr. Mosher asked why some GA jet operators, such as Regency Air, operate at lower dB levels during the curfew hours relative to daytime operations. Mr. Gaskins presumed it was probably due to different weights and departure procedures utilized by the pilots. Mr. Bress asked if the ANO knows the metrics associated with the noise from Alaska Airlines departures. Mr. Bress said he has publicly stated that "Alaska is bad" and "Alaska is not a good neighbor" and that Alaska typically operates faster, lower, and registers four decibels louder than the other airlines. Mr. Bress added that in previous discussions with Airport Director, Ms. Charlene Reynolds, she stated there would be some opportunities to contact Alaska to discuss the issue. Mr. Gaskins stated the ANO is currently working on an analysis comparing the year- to-year altitudes of each of the carriers. Mr. Gaskins added that over the past several weeks, the ANO has met with corporate executives from each airline at JWA to present an Access Plan overview. However, the Airport does not have the authority to demand a carrier to fly a particular aircraft or how to fly a specific departure procedure. Mr. Gaskins emphasized that the Airport can only recommend those items, which the Airport has previously done numerous times.

Mr. Gaskins stated point values had already been determined for the program but added it is something the Airport may look at in the future since some GA jet operators appear to operate differently between the daytime/nighttime hours. Mr. Gaskins introduced Mr. Kyle Gorny, JWA's new ANO Specialist, and briefly discussed his qualifications and previous experience. Dr. Mosher asked about the flight data on the City of Newport Beach's dashboard. Dr. Mosher questioned whether the delay was an Airport or City issue. Mr. Gaskins explained the Airport typically sends the information to the City of Newport Beach three weeks after the end of the month reported. However, the recent delay was due to the issues mentioned earlier. Mr. Bress expressed that the Airport continues to have non-compliant departures with FAA 14 CFR 91.117(a) & 14 CFR 91.117(b) and that JWA is Class C airspace. Mr. Bress also inquired if JWA has made any progress on his previous requests to post information to pilots on JWA's website stating the Airport is in Class C airspace, as well as include a reference to what that means in regards to being compliant with FAA 14 CFR 91.117(a) & 14 CFR 91.117(b). Mr. Gaskins mentioned that pilots use other resources to obtain FAA FAR information, so the Airport does not intend to post FAA FARs on the website. Mr. Gaskins stated he would bring the request to the Airport Director for direction. Mr. Bress also expressed that in the Zoom meeting hosted by the Airport Director, the FAA said they do not want any non-compliance with FAA 14 CFR 91.117(a) & 14 CFR 91.117(b). Mr. Bress said he has screenshots of non-compliance and wanted to know if the Airport would agree in general that a departure that was "faster and thrusting" and in non-compliance with FAA 14 CFR 91.117(a) & 14 CFR 91.117(b) would be louder than one that was compliant. Mr. Gaskins stated it would depend on certain variables and would like to see how Mr. Bress came to that conclusion. Mr. Gaskins reiterated what the FAA said in the previously mentioned FAA Community Workshop webinar, which was that airspeed values on public websites are based on the "ground speed" of the aircraft and not the criteria used for enforcement, which is "indicated airspeed." Mr. Bress asked who oversaw the Airport's social media posts and if that person was receiving notifications, specifically on Twitter and Facebook. Mr. Bress stated he forwarded communication through those platforms and wanted to ensure JWA had seen those posts. Mr. Gaskins confirmed JWA has a dedicated person who monitors all social media platforms and responds accordingly.

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 ½ 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 (July 1, 2022 -June 30, 2023). 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". 1 DocuSign Envelope ID: A0660571-3C85-4ADA-BAF8-303A765A514BDocuSign Envelope ID: E556D097-C0B9-4B73-BB9C-8207B495A271 JOHN WAYNE AIRPORT ORANGE COUNTY :,, .., <,Y,!;)...,_~l-~..

Insufficient data is indicated by "#N/A" 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-four dwelling units in Santa Ana Heights remain in the "Noise Impacted Area" (within 65 dB CNEL contour). COMPLAINT TOTALS (April 1, 2023 -June 30, 2023) The Airport's Access and Noise Office receives and investigates noise complaints (noise events) from local citizens and all other sources.

Mr. Allensworth said he contacted the Federal Aviation Administration (FAA) and Congresswoman Young Kim’s office regarding his concerns. Mr. Allensworth mentioned that it appears aircraft are adjusting their rudders when overflying his neighborhood. Mr. Allensworth asked why the FAA has not reverted back to the previous flight path used before 2017. Mr. Anthony Cangey, Airport Access & Noise Specialist at John Wayne Airport, responded to Mr. Allensworth's concerns by stating he went through the proper channels by contacting the FAA. Mr. Cangey added that JWA strictly enforces aircraft access and noise restrictions, as prescribed in the Settlement Agreement and Phase 2 Access Plan. Mr. Allensworth mentioned he has spoken with other concerned neighbors and these residents feel they may be forced to move if aircraft noise continues. Mr. Allensworth also expressed that aircraft activity near his residence may negatively affect home values in his neighborhood. Mr. Cangey encouraged Mr. Allensworth to contact the JWA Access & Noise Office to further discuss these concerns. Newport Beach resident, Dr. Jim Mosher, asked about the status of the aircraft altitude analysis and the results of that study. Mr. Cangey explained that the data used in the altitude analysis for each year is collected from the month of August, so the presentation was going to be postponed until September or October to include August 2023 data. Dr. Mosher asked when the results of the Fly Friendly Program would be presented to the public. Mr. Cangey stated the results will be announced in Fall 2023. Mr. Cangey also added that JWA is still in communication with Fifth District County Supervisor Katrina Foley's office and the JWA Advisory Committee during this process. Mr. Cangey also added that JWA continues to collaborate with GA pilots for outreach and program improvements. Dr. Mosher wanted to know the status of the 2024 Plan Year capacity allocations. Mr. Cangey mentioned staff recommendations would be made public on June 28, presented to the Airport Commission on July 5, followed by Board of Supervisors’ action on July 15. Dr. Mosher noticed in the Quarter 1 2023 Noise Report that commercial carriers are flying newer, quieter aircraft less frequently than in the past, and asked if this was a result of changes in capacity allocations when compared to last year. Mr. Cangey explained that the types of aircraft that commercial carriers operate at JWA are at their discretion. Mr. Cangey added that United Airlines recently submitted a noise qualification test packet to receive approval to operate the Boeing 737-8 MAX at JWA. Dr. Mosher had commented that in ten percent of the General Aviation (GA) violations listed in the Detailed Noise Events Reports, the call sign was listed as “UNKNOWN”, and he wanted to know if the Airport resolves violations that show as UNKNOWN. Mr. Cangey explained that if a call sign is listed as UNKNOWN in JWA’s Airport Noise and Operations Management System (ANOMS), the ANO will utilize other sources to obtain this information and update records in ANOMS. 15 DocuSign Envelope ID: A0660571-3C85-4ADA-BAF8-303A765A514BDocuSign Envelope ID: E556D097-C0B9-4B73-BB9C-8207B495A271 JOHN WAYNE AIRPORT ORANGE COUNTY Noise Abatement Program Quarterly Report April – June 2023 Dr. Mosher stated that in the General Aviation Noise Ordinance (GANO), a violation is assigned to the operator/owner of the aircraft, but in the Semi-Annual GANO report the Airport states that the violation letter is sent to the registered owner, and he is not clear who is regarded as the operator. Dr. Mosher provided a specific example and asked if Clay Lacy, who operates charter aircraft at JWA, would be considered the operator or the pilot of each aircraft under Clay Lacy. Mr. Cangey stated JWA sends GANO violations to the registered owner, the operator, and the pilot-in-command, when contact information is available. Mr. Cangey mentioned that the violation is tied to the tail number of the aircraft. Dr. Mosher asked why the public is only made aware of the number of GANO violations throughout the year and why it appears some of those violations are excused. Dr. Mosher asked if there is any reason JWA cannot be more transparent and publish a list of the GANO violations that are waived, as the Airport does with its commercial curfew operations. Mr. Cangey said he would discuss these recommendations with Airport management. Dr. Mosher stated that in the latest Quarterly Noise Report, JWA no longer provided the complaints heat map, but instead, now provides “doughnut” diagrams showing the "nature of the complaint." Dr. Mosher found it odd that the predominant complaint was not “too loud” but instead “off-course” or “too frequent.” Dr. Mosher asked if the system only allows the ability to submit one option for the nature of the complaint and not multiple reasons. Mr. Cangey confirmed that the system only enables complainants to submit one option for the nature of the complaint. Mr. Cangey added that for this specific report, the nature of complaints submitted from Anaheim Hills were listed as “off-course” and “too frequent”, which resulted in a higher percentage of these types. Dr. Mosher expressed that the complaint data is not meaningful because it is a self-selected group of people affecting the statistics. Dr. Mosher asked if the ANO has attempted to see which kind of planes or carriers are generating the most complaints, like Alaska Airlines, as mentioned in previous meetings. Mr. Cangey explained that the IoT button tags the closest aircraft at the time and place of the complaint. Dr. Mosher asked how many complaints received each quarter require a response and how much time does it take to complete that task. Mr. Cangey said that since Viewpoint was implemented, the ANO's protocol is if the Airport receives a complaint from the IoT button, we will not respond to the complaint. For all other submission methods, if a complainant requests a response, our office will respond to the first complaint submitted by that complainant for that day, which equates to approximately 6-12 daily complaints. 16 DocuSign Envelope ID: A0660571-3C85-4ADA-BAF8-303A765A514BDocuSign Envelope ID: E556D097-C0B9-4B73-BB9C-8207B495A271 JOHN WAYNE AIRPORT ORANGE COUNTY Noise Abatement Program Quarterly Report April – June 2023 QUARTERLY NOISE MEETING ROSTER June 27, 2023 NAME ORGANIZATION Jim Mosher Resident – Newport Beach Roger Allensworth Resident – Anaheim Hills Jason Herman Air Line Pilots Association, International Unknown Caller Unknown Anthony Cangey John Wayne Airport Beatrice Siercke John Wayne Airport Cristina Magaña John Wayne Airport Kyle Gorny John Wayne Airport 17 DocuSign Envelope ID: A0660571-3C85-4ADA-BAF8-303A765A514BDocuSign Envelope ID: E556D097-C0B9-4B73-BB9C-8207B495A271 SUMMARY OF STATISTICAL INFORMATION FOR CALIFORNIA DEPARTMENT OF TRANSPORTATION 1.
