PARKER, CITY MANAGER COMMUNITY DEVELOPMENT DEPARTMENT Agenda Item 5 Reviewed: City Manager Finance Director N%A JOHN WAYNE AIRPORT NOISE ABATEMENT QUARTERLY REPORT This agenda report transmits the John Wayne Airport (JWA) Noise Abatement Quarterly Report for the fourth quarter of 2014. The average noise level measured at Tustin's monitoring station (NMS 1ON), located at Columbus Tustin Middle School on Beneta Way (Figure 1), remained consistent with prior quarters during this fourth quarter reporting period; however, noise level data was unavailable for a majority of the month of December due to technical difficulties with the monitoring equipment at this site. Average noise levels during the fourth quarter were well 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. Figure 1 JWA Noise Report May 20, 2015 Page 2 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, in this instance, on matters of airport traffic and noise. 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 is the quarterly report for the fourth quarter of 2014, which includes the months of October through December. An overview of the information contained within the JWA Noise 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; emergencies; and, weight — a heavier load may affect an aircraft's rate of ascent. During the fourth quarter of 2014, the average CNEL at Tustin's monitoring station on Beneta Way was 54.5 dB. This is .5 dB lower than the average of the previous quarter (Q-3: July through September 2014). The average noise level for this quarter is very similar to the average from the previous four quarters, which is 55.1 dB. Figure 2 provides a visualization of Tustin's CNEL levels for each month during the fourth quarter of 2014.

Within this quarter's noise report, John Wayne Airport indicated that Tustin's monitoring station was inoperable for most of the month of December, making data collection unavailable. John Wayne Airport stated that the outage was due to a technical problem requiring extensive troubleshooting before functionality could be restored. Functionality was restored to this site by mid-January 2015. Noise Complaints The Airport's Access and Noise Office receives and investigates noise calls and complaints from local citizens and other sources. Throughout all of the Orange County monitoring area, noise complaints decreased by 61.5 percent during the fourth quarter of 2014 in comparison to the third quarter. This represents a 70.5 percent decrease in comparison to the same quarter last year. It should be noted that several of the complaints were made by the same households from the cities of Costa Mesa and Irvine. During the fourth quarter of 2014, there were eight (8) Tustin area complaint calls, compared to nine (9) complaints during the previous quarter. Tustin staff has outreached to John Wayne Airport to gather further details on the nature of the complaints made by residents. The breakdown of the eight (8) complaints from the fourth quarter of 2014 are as follows: three (3) were related to aircraft noise late at night; one (1) was related to an aircraft that appeared off -course; one (1) was related to general aircraft noise; one (1) was related to aircraft which appeared to be flying low; and, one (1) was related to an aircraft which was flying both low and loud. 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 five years is displayed below (Figure 3). Generally, there is a noticeable increase in noise complaints during the second and third quarters, which further supports the theory that an increase in complaints tends to occur during the warmer months of spring and summer. Overall, the number of complaints has not reached more than twelve (12) complaints in a single quarter during this five-year reporting period. 14 N c 12 M a 10 0 8 u 'p G `a 4 .c E 2 0 Noise Complaints - Tustin 4til~oC,VkT�0�`�010�.\T 111�T�y0y��10�-5\T NKT�4�,,\'P ti�ti��41,11KV ��\tidy '\V _V9�03��0b�P�QtilVa 0 Oal��a Quarter/Year Figure 3 JWA Noise Report May 20, 2015 Page 4 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.

Adrianne DiLeva-Johnson Senior Management Assistant Elizabeth A. Binsack Director of Community Development Attachment: John Wayne Airport Noise Abatement Quarterly Report for October 1, 2014, through December 31, 2014 ATTACHMENT John Wayne Airport Noise Abatement Quarterly Report for October 1, 2014 through December 31, 2014 (Fourth Quarter) NOISE ABATEMENT PROGRAM QUARTERLY REPORT For the period: October 1, 2014 through December 31, 2014 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: Lawrence G. Serafini Acting Airport Director John Wayne Airport, Orange County INTRODUCTION This is the 168th 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 -8N: 17372 Eastman Street, Irvine NMS -4S: 2338 Tustin Ave., Newport Beach NMS -9N: 1300 S. Grand Avenue, Santa Ana NMS -5S: 324'/2 Vista Madera, Newport Beach NMS -ION: 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, 2014 - December 31, 2014). 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".

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-two dwelling units in Santa Ana Heights remain in the "Noise Impacted Area" (within 65 dB CNEL contour). TELEPHONE COMPLAINT CALLS (October 1, 2014 - December 31, 2014) The Airport's Access and Noise Office receives and investigates noise calls and complaints from local citizens and all other sources. During October 1, 2014 through December 31, 2014, the Office received 190 complaints from local citizens. This is a 61.5% decrease from the 494 complaints received last quarter. It is a 70.5% decrease from the 643 complaints received during the same quarter last year.
