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 2001. The average noise level measured at monitoring station
NMS 10N, located at Columbus Tustin Middle School, slightly increased during the third
and fourth quarters. 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
That the City Council receive and file this report.
FISCAL IMPACT
On December 18, 2001, the City Council authorized Wieland Associates 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.
Attachment A contains the quarterly reports for the third and fourth quarters of 2001.
Attachment B contains the summary report prepared by the noise consultant. A brief
overview of the information contained within these attachments is as follows:

Measured Noise Levels
During the third quarter of 2001, the average CNEL at Remote Monitoring Station
(NMS) 10N, located at Columbus Tustin Middle School was 56.7 dB. This is .3 dB
less than the four previous quarters. However, for comparison, the CNEL was .3 B
higher (57.0) during the third quarter of 2000.
During the fourth quarter of 2001, the average CNEL was 57.0 dB. This is the
same average as the four previous quarters. For comparison, the CNEL was .3 dB
lower (56.7) during the fourth quarter of 2000.
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 2001, there were 17 Tustin area complaints compared
with 16 for the same period during 2000.
During the fourth quarter of 2001, there were 7 Tustin area complaints compared
with 17 for the same period during 2000.
The number of complaints decreased during the third and fourth quarters compared
to the same period in 2000. The overall number of complaints dudng the last two
quarters of 2001 does not appear to correlate with the average quarterly aircraft
CNEL nor with the number of quarterly jet operations at the airport. The average
quarterly aircraft CNEL increased steadily from the fourth quarter of 2000 through
the second quarter of 2001, while the number of complaints from residents of the
Tustin area remained relatively steady. The number of complaints in the fourth
quarter of 2001 actually dropped even though the average quarterly CNEL
increased.
Type and Mix of Aircraft Related to Noise Levels
During the third quarter of 2001, the percentage of quieter Class E aircraft
increased and the percentage of noisier Class A aircraft decreased compared with
the same period in 2000. The average CNEL for the third quarter of 2001 was
slightly lower than the same period during 2000.
During the fourth quarter of 2001, the percentage of quieter Class E aircraft
increased and the percentage of noisier Class A aircraft decreased compared with
JWA Noise Report
August 5, 2002
Page 3
the same period in 2000. The average CNEL for the fourth quarter was slightly
higher than the fourth qUarter of 2000.
The percentage of quieter Class E aircraft using John Wayne Airport has gradually
increased since the beginning of 2000. This percentage increase in Class E aircraft
was offset by a decrease in the use of the noisier Class AA aircraft. Based on data
from the third quarter of 2000 through the fourth quarter of 2001, there appears to
be a correlation between the aircraft mix and the average quarterly CNEL at NMS
10.
Airport Noise Contours
Wieland and Associates, Inc. utilized a noise contour in preparing the attached report.
This noise contour is based on the 2001 contours developed by the noise consultant
for the John Wayne Airport Noise Abatement office. Using this contour, it is estimated
that in 2001 the aircraft-generated CNEL in Tustin ranged from about 59 dB to less
than 55 dB. This is well below the City, County, and State criteria of 65 dB for
residential areas.
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.

INTRODUCTION
This is the 115th 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 (NMS) located in Newport Beach,
Santa Ana, Tustin and Irvine to measure noise levels, at the following locations:
MONITOR STATIONS
NMS- 1 S: Golf Course, 3100 Irvine Ave., Newport Beach
NMS-2S: 20152 S.W. Birch St., Santa Ana
NMS-3S: 2139 Anniversary Lane, Newport Beach
NMS-4S: 2338 Tustin Ave., Newport Beach
NMS-5S: 324 V2 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, 2000 -
September 30, 2001). 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".

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 GA Jet aircraft are shown in Tables
6 through 8.
For the twelve month period ending September 30, 2001, 102 dwelling units in Santa Ana Heights were in the "Noise
Impacted Area" (within the 65 dB CNEL contour); this represents a decrease of one unit in the number of dwelling
units in the "Noise Impacted Area" from the previous twelve month period ending June 30, 2001.
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 Pro,am, 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 2001 , no additional residences have been made compatible
through the County's SAH AIP. A total of 267 residences in Santa Ana Heights have been purchased or otherwise
made compatible through the County's Purchase Assurance Pro,am, Housing Relocation Program, Acoustical
Insulation Program or SAH AIP.
TELEPHONE COMPLAINT CALLS (July 1, 2001 - September 30, 2001)
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 1,2001 through September 30, 2001, the Office received 643 complaints from
citizens. This is a 13.0% increase from the 569 complaints received last quarter. It is a 2.6% decrease from the 660
complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly telephone calls
and complaints from local communities.

INTRODUCTION
This is the 116th Quarterly Report submitted by the County of Orange in accordance with the
requirements of the Califomia 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 (NMS) located in Newport Beach,
Santa Ana, Tustin and Irvine to measure noise levels, at the following locations:
MONITOR STATIONS
NMS- 1 S: Golf Course, 3100 Irvine Ave., Newport Beach
NMS-2S: 20152 S.W. Birch St., Santa Ana
NMS-3S: 2139 Anniversary Lane, Newport Beach
NMS-4S: 2338 Tustin Ave., Newport Beach
NMS-5S: 324 V2 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- 1 ON: 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 1,2001 -
December 31,2001). 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".

NOTE: (1) GA Jet figures include a 5% factor for operations not identified by the JWA noise monitor stations.
(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 GA Jet aircraft are shown in Tables
6 through 8.
For the twelve month period ending December 31, 2001, 102 dwelling units in Santa Ana Heights were in the "Noise
Impacted Area" (within the 65 dB CNEL contour); there was no change in the number of dwelling units in the "Noise
Impacted Area" from the previous twelve month period ending September 30, 2001.
The State has approved several remedies of aircraft noise levels for noise sensitive property in the "Noise Impact
-4-
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 fourth quarter of 2001, an additional 182 residences have been made
compatible through the County's SAH AIP. A total of 449 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, 2001 - December 31, 2001)
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 1,2001 through December 31,2001, the Office received 207 complaints
from citizens. This is a 67.8% decrease from the 643 complaints received last quarter. It is a 33.9% decrease from
the 313 complaints received during the same quarter last year. Figure 4 shows the distribution of the quarterly
telephone calls and complaints from local communities.

NOISE ABATEMENT COMMITTEE MEETING
Date: December 27, 2001
Time: 2:00 pm
Place: Eddie Martin Building
AGENDA ITEMS AND ITEMS DISCUSSED:
1. Airport Statistics
John Escobedo gave a summary on the Airport Statistics citing information published in the
JWA Airport Statistics report for November 2001. He noted decreases from Novmber 2000
levels in total passengers, air cargo tonnage lifted, general aviation operations, air carrier
operations, air taxi operations and total operations, due primarily to the effects of the tragic
events of September 11th.
2. Status of the Santa Ana Heights Acoustical Insulation Program (SAHAIP)
Carl Braatz provided an update on the status of the SAHAIP. He noted that the AIP Phase Vll,
the 182 unit apartment building located at the comer of Mesa Drive and Irvine Avenue is now
complete. The Notice of Completion was recorded on December 6, 2001. The total cost of
insulation for the apartment building was $1.7 million. The apartment building is now in a
yearlong warranty period. For AIP Phase VIII, construction is due to begin on 25 single family
dwellings on January 7, 2002. An additional 10 homes are in the design phase.
3. Any additional questions
None.
4. Tentative date for the next Noise Abatement Committee meeting
The date for the next quarterly Noise Abatement Committee meeting will be announced by
letter approximately two weeks before the meeting.

Review of John Wayne Airport Noise Abatement Program
Quarterly Reports

Subject:
Review of John Wayne Airport Noise Abatement Program
Quarterly Reports for the 3rd and 4th Quarters of 2001
Dear Ms. Willkom,
As requested, we have reviewed the referenced quarterly reports for the noise
abatement program at John Wayne Airport. The following provides our
findings with regard to airport operations and their impact on the City of
Tustin:
e
ge
Referring to Figure 1, the average annual CNEL at NMS I0N was 57.0 dB
for 2001 based upon data for all four quarters. This is 0.3 dB lower than
the average annual CNEL of 57.3 dB for 2000. (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 57.0 dB in 2001 implies the leveling off of a
modest upward trend in the aircraft noise exposure measured at NMS 10N.
This trend is illustrated in the following table:
1994
1995
1996
1997
1998
1999

56.1 dB
56.4 dB
56.8 dB
55.9 dB
57.0 dB
56.8 dB
57.3 dB
57.0 dB
Referring to Figure 2, the number of noise complaints received from the
Tustin area does not appear to correlate with the average quarterly aircraft
CNEL measured at NMS 10N, nor with the number of quarterly jet
operations at the airport. As indicated in the figure, the average quarterly
CNEL increased steadily from the fourth quarter of 2000 through the
second quarter of 2001, while the number of complaints from residents of
the Tustin area remained relatively steady. The number of complaints in
the fourth quarter of 2001 actually dropped even though the average
quarterly CNEL increased.

As indicated in Item 1, above, the annual average CNEL measured at NMS 1 ON was
57.0 dB in 2001. 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.
Aircraft Noise Contours
Figure 3 provides the estimated location of the John Wayne Airport noise contours for
2001. These are based on the 2001 contours developed by the John Wayne Airport Noise
Abatement Office, and data through the fourth quarter of 2001. Referring to Figure 3, it is
estimated that in 2001 the aircraft-generated CNEL ranged from about 59 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 John Wayne Airport
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 2000 and the fourth quarter of 2001. 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 gradually increased since the beginning of 2000. This increase in
Class E aircraft was offset by a decrease in the use of the noisier Class AA aircraft.
However, during this same time period, the average quarterly CNEL has been relatively
steady. Therefore, based on data from the first quarter of 2000 through the fourth quarter
of 2001, there does not appear to be any correlation between the aircraft mix and the
average quarterly CNEL at NMS 1 ON.
