TO: WILLIAM A. HUSTON, CITY- MANAGER
FROM: COMMUNITY DEVELOPMENT DEPARTMENT
SUBJECT: JO~N WAYNE AIRPORT STATUS REPORT
RECOMMENDATION
That the City Council receive and file this report.
FISCAL IMPACT
The City retains the acoustics consulting firm of J.J. Van Houten
and Associates, Inc. for review of noise-related items. The costs
for such reviews are annually included in the Community Development
Department budget.
BACKGROUND
The Community Development Department currently contracts with an
acoustics consultant to review the John Wayne Airport Noise
Abatement Program Quarterly Reports prepared by the County of
Orange. On September 21, 1987, the City Council authorized these
reviews to monitor airport noise issues as a result, of concerns
from many Tustin residents. Previously,-the consultant prepared a
report for each quarterly report. However, to reduce costs
associated with the consultant review, staff has requested that the
consultant prepare a report twice a year which summarizes the two
quarterly reports.
Although the'County has previously been approximately nine months
behind in distributing quarterly reports, the City recently
received several quarterly reports. This status report transmits
three quarterly reports for the period of October 1, 1994 through
June 30, 1995.
The consultant's review focuses on noise measurements taken at
Remote Monitoring Station #7, located at Columbus Tustin. Middle
School. Noise measurements are converted into a "Community Noise
Equivalent Level" (CNEL) which is a cumulative measure of nOise
exposure over a specified period of time. Typically, CNEL measures
noise exposure levels over a 24-hour period and places greater
significance on noise events that occur in the evening or

nighttime/early morning hours. For the quarterly reports, CNEL
data is averaged over each quarter.
The consultant's analysis also focuses on other information
contained within the quarterly reports including the number of
complaints received by airport staff as well as the number of
flights, type,' and classification of aircraft.
DISCUSSION
Attachment 1 contains three quarterly reports for the period of
October 1, 1994 through June 30, 1995. Attachment 2 contains two
summary, reports prepared by the noise consultant. The first report
summarizes information contained within the report for the fourth
quarter of 1994 (October 1, 1994 to December 31, 1994). The second
report summarizes information for the first quarter of 1995
(January 1, 1995 to Mazch 31, 1995) and the second quarter of 1995
(April 1, 1995 to June 30, 1995).
Between October 1, 1994 and June 30, 1995, the average quarterly
CNEL increased slightly. The average CNEL at Remote Monitoring
Station #7 was 56.1 dB during the fourth quarter of 1994, 56.3 dB
during the first quarter of 1995, and 56.9 dB CNEL during the
second quarter of 1995. In comparison,, these levels are either
less than or only .2 dB higher than the average annual CNEL of 56.7
dB for 1993 and are below the City, County and State criteria of 65
dB CNEL for residential areas.
John Wayne Airport's Access and Noise Office receives and
investigates noise complaints for local citizens and other sources.
Between October 1, 1994 and June 30, 1995, the number of
Tustin/Orange complaints the office received remained fairly
constant. There were thirty-nine (39) complaints during the fourth
quarter of 1994 compared with nineteen (19) for the fourth quarter
of 1993, forty-one (41) complaints during the first quarter of 1995
compared with thirty (30) for the first quarter of 1994, and forty-
two (42) complaints'during the second quarter of 1995~Compared with
twenty-nine (29) for the second quarter of 1994. Complaints
received from the cities of Tustin and Orange and the County
unincorporated area north of Tustin are combined for reporting
purposes. However, staff at the Access and Noise Office indicated
that almost all of these complaints originate from locations under
the flight path within Tustin's corporate boundaries.

Although no clear correlation between CNEL and the type and mix of
arriving ~and departing aircraft has been observed, John Wayne
Airport tracks this information. The Federal Aviation
Administration (FAA) classifies aircraft based on noise levels. In
order of decreasing noise levels, there are Stage I, Stage II, and
Stage III aircraft'. Only Stage III aircraft have-been permitted at
JWA since the early 1970's. This is the quietest FAA
classification of aircraft in terms of noise generated at take-off~
.John Wayne Airport also classifies Stage III passenger 'aircraft
into 'Class A, Class AA, and Class E based on their noise levels.
.
Class E aircraft produce the lowest-noise levels during take-offs.
However, in some cases, Class E aircraft generate more noise on
arrival than Class A or ClaSs AA.
Between October 1, 1994 and June 30,~ 1995, the use of quieter Class
E aircraft decreased and the use of noisier Class A aircraft
slightly increased. With the use of noisier aircraft, the average
quarterly CNEL slightly increased.
The three complete Noise Abatement Program Quarterly Reports and
the two City's noise consultant's reviews are attached for the
Council's consideration.
CONCLUSION
Since the issues discussed above are of considerable importance to
the City of Tustin, the Community Development Department will
continue to monitor airport noise issues unless otherwise directed
by the City Council.

INTRODUCTION
This is the 90th 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 crtefia for defining "Noise Impact Area" was changed from 70 dB to
65 dB Community Noise Equivalent Level (CNEL). Under this criteria, the Airport has a
"Noise Impact Area."
OPERATIONAL S~RY
Caltrans' Division of Aeronautics 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 monitoring stations (RMS)
located in Newport Beach, Santa Ana, Tustin and Irvine to measure noise levels, at the
following locations: '

Figure I shows the Airport's "Noise Impact Area" for the previous year (July 1, 1994 - June 30,
1995). The Figure 1 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 and number of
residences within the "Noise Impact Area".

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 "0.0" entries in each table.
Average Single Event Noise Exposure Level (SENEL) values for air carrier and business jet aircraft are
shown in Tables 6 through 8.
..
For the twelve month period ending June 30, 1995, 66 dwelling units in Santa Ana Heights were in the
"Noise Impacted Area" (65 dB CNEL); there was an increase of 13 in the number of dwelling units in
the "Noise Impacted Area" from the previous twelve month period ending March 31, 1995.
The State has approved several remedies of aircraft noise levels for property owners in the area: the
homes can be acoustically insulated, purchased by the County, or rezoned for "other non-noise sensitive
uses." As part.of the County's Santa Aha Heights Land Use Compatibility Program, approximately' 77
general agriculture (A-l) 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 sUbsequentiy
converted to compatible land use. In September 1993, the FAA approved a gant to fund a voluntary
Accelerated Acoustical Insulation Pro,am (AAIP) in Santa Aha Heights. There have been 139
residences purchased or otherwise made compatible through the County's Purchase Assurance Program,
Housing Relocation Plan, Acoustical Insulation Program or AAIP.
TELEPItONE COlVlPLAINVr CALLS (April- June 1995)
The Airport's Access and Noise Office receives and investigates noise complaints from local citizens and
all other sources. During the second quarter of 1995, the Office received a total of 368 complaints from
local citizens, a 36.8% increase from the 269 complaints received during the previous quarter and a
decrease of 29.2% from the 520 complaints received during the same quarter of 1994. Figure 3 shows
the local geographic area distribution of the quarterly telephone complaints.

The meeting was chaired by John Leyerle, Chief, Access and Noise, for John Wayne Airport.
CONTINUING BUSINESS
.
Santa Ana Heights, Accelerated Acoustical Insulation Program Status - Progress is slower
than (airport) would like; fifteen homes completed (out of 250). There are several agencies
involved: Environmental Management Agency, General Service Agency: Facilities
Operations and Real Estate divisions. Funding:' In September 1993 - $4 million was
received from the FAA, 1994 - an additional $2 million was received from FAA. FAA will
provide 80% of total funding; County will provide remaining 20% (may or may not be
funded in current fiscal year).
.
Ur>grade of Noise Monitoring System - Current system was purchased in 1979. Mid-June
(June 13) Board of Supervisors will have opportunity to approve purchase of new system.
Cost will be approximately $1 million. Will be installed and accepted over the next year and
a half. New system will provide at least same level of noise monitoring and hopefully more.
[To carrier representatives] Meetings will be held over the next few months to discuss things
they might like to get out of new system. Letter from Airport Director will be forthcoming
with invitation to meet.
Question from Rene, Station Manager of USAir: How will we pay for this?
Response from John Leyerle (JL): From the Airport's funds, amortized over a number of
years.
Question from Delta .Representative:. Explain the difference between the old and new
systems?
Response from JL: Microphones in the field, electronics in the field, central computer in
the office, new system will provide new hardware/software to integrate all information
sources that are now merged manually.
Question from Martin South, Riverside Kennel Association: Are they going to put monitors
higher or trim threes near them?
Response from JL: The Airport will trim trees, currently has a requisition in for this to be
done, will be trimmed sometime during next two months. The monitor locations and heights ·
will remain the same.

New Carriers - United Parcel Service, Federal Express, Arizona Airways.
Question from Renee, USAir: Who is doing the ground handling for Arizona Airways?
Response from JL: American Eagle.
Aircraft Flight Tracks - The Access and Noise Office periodically gets calls regarding flights
perceived as off-course by residents. The Noise Office's PASSUR equipment gives the same
information as the tower's display, and serves to give an impression of the preponderance
of off-course departures. Regarding off-course flights: 1) the Airport is not responsible for
flight paths; 2) we will pass on information on off-course flights at the Noise Abhtement
Committee Meetings and the Airline Affairs meetings; and 3) carriers can then do what they
will with the information.
Question from Martin South, Riverside Kennel Association: American Eagle and United
Express go over his house in Santa Ana Heights at 500 feet (in .altitude).
Response from JL: Call the Noise Office to let us know when this.happens. When a
weather cell is out over the 'ocean, planes will turn right and go over Huntington Beach.
Heavy weather and wind conditions cause the tower to direct aircraft elsewhere.
Response from Martin South: This happened on April 1st. Also, sometimes 757s, etc. go
over his house very low on clear days.
Response from JL: MegaData (vendor for PASSUR system) says their system is accurate
to plus or minus 400 feet, tests by our consultant show it is accurate to plus or minus 200
feet.

INTRODUCTION
This is the 891h Quarterly Report submitted by the County of Orange in accordance with the
requirements of the California Airport Noise Standards (California Adminigtrative Code
Title 21, Chapter 2.5, SubChapter 6: Division of Aeronautics Noise Standards). Effective
lanuary 1, 1986, the criteria for defining "Noise Impact Area" was changed from 70 dB to
65 dB Community Noise Equivalent Level (CN~-). under this criteria, the Airport has a
"Noise Impact Area."
OPERATIONAL SUMMARY
Caltrans' Division of Aeronautics 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 (C2q~-) of more than 65 dB define the 'Noise
Impact Area.~ John Wayne Airport uses ten permanent remote monitoring st_a__tlons (RMS)
located in Newport Beach, Santa Aha, Tustin and Irvine to measure noise levels, at the
following locations:

RMS-24:1918 Santiago, Newport Beach
RMS4 and RMS-5, which have been in service for a number of years, have been diScontilaued
from operations. JWA will no longer report data from RMS4 or RMS-5, effective lanuary 1,
1995. In June 19931 the Orange County Board of Supervisors approved replacement of these
two RMSs by three new stations, numbers 21, 22 and 24. These three new stations are closer
to the aircraft typical flight path than RMSs 4 and 5, and they tend to collect more
representative noise level data from each aircraft operation. During the. 18 months since the
Board's approval of RMS4 and RMS-5 decommissioning and removal, those two stations have
been operated in parallel with the three new stations. Beginning with tiffs Quarterly Report,
JWA will report noise level data for only the m...maining ten stations. '
Figure I shows the Airport's "Noise Impact Area" for the previous year (April 1', 1994 -
March 31, 1995)., The Figure 1 information was developed by Mestre-Greve Associates, Inc.,
in consultation with'John Wayne Airport. CN-~- values measured for the periOd and current
digitized land use information, were ufili?ed to calculate the land area acreages and number of
residences within the "Noise Impact Area".

CO~ NOISE EQLrIVAI.ENT 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 '0.0" entries in each table.
Average Single Event Noise Exposure Level (SENEL) values for air carrier and business jet aircraft are
shown in Tables 6 through 8.
For the twelve month period ending March 31, 1995, 53 dwelling units in Santa Ana Heights were in the
"Noise Impacted Area" (65 dB CNEL); there was an increaseof 13 in the number of dwelling'units in
the "Noise Impacted Area" from the previous twelve month period ending December 31, 1994.
.
..
The State has approved several remedies of aircraft noise, levels for property owners in the area: the
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-I) properties with residential land uses on Orchard, Acacia and Birch Sweets were
rezoned for Business Park Use in October, 1986. Each property was individually sold and subsequently
converted to compatible land use. In September 1993, the FAA approved a grant to fund a voluntary
Accelerated Acoustical Insulation Program (AAIP) in Santa Aha Heights. There have been 139
residences purchased or otherwise made compatible through the County's Purchase Assurance Program,
Housing Relocation Plan, Acoustical Insulation Program or AAIP.
TELEPHONE COM]PLAINT CAI,IS (Jan,raaw- March 1995)
The Airport's Access and Noise Office receives and investigates noise complaints from 'local citizens and
all other sources. During the first quarter of 1995, the Office received a total of 269 complaints from
local citizens, a 7.8 % decrease from the 292 complaints received during the previous quarter and a
decrease of 22.9 % from the 349 complaints received during the same quarter of 1994. Figure 3 shows
the local geographic area distribution of the quarterly telephone complaints.

Interim Airport Director
John Wayne Airport, Orange County
INTRODUCTION
This is the 88th 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, the Airport has a
"Noise Impact Area."
OPERATIONAL SUMMARY
Caltrans' Division of Aeronautics 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 twelve permanent remote monitoring stations (RMS)
located in Newport Beach, Santa Ana, Tustin and Irvine to measure noise levels, at the
following locations:
RMS-I:

Figure 1 shows the Airport's "Noise Impact Area" for the previous year . (january 1, 1994 -
December 31, 1994). The Figure 1 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 acreage and
number of residences within the "Noise Impact Area".

COM3/IUNITY NOISE EQUIVALENT
The month/y, 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 "0.0" entries in each table.
Average Single Event Noise Exposure Level (SENEL) values for air carrier and business jet aircraft a~e
shown in Tables 6 through 8.
For the twelve month period ending December 31, 1994, 40 dwelling units in Santa Ana Heights were in
the "Noise Impacted Area" (65 dB CNEL); there was no change in the number of dwelling units in the
"Noise Impacted Area" from the previous twelve month period ending September 30, 1994.
The State has approved several remedies of aircraft noise levels for property owners in the area: the'
homes can be acoustically insulated, purchased by the County, or rezoned for "other non-noise sensitive
use." As part of the County's Santa Ana Heights Land Use Compatibility Program, approximately 77
general agriculture (A-l) properties with residential land uses on Orchard, Acacia and Birch Streets were
re. zoned for Business .Park ,Use in October, 1986. Each property was individually sold and subsequently
convened to compatible land use. In September 1993, the FAA approved a grant to fund a voluntary
Accelerated Acoustical Insulation Program (AA[P) in Santa Aha Heights. There have been 139
residences purchased or otherwise made. compatible through the County's Purchase Assurance Program,
Housing Relocation Plan, Acoustical Insulation Program or AAIP.
TELEPHONE COMPLAINT CAIJ.S (October - December 1994) .'
The Airport's Access and Noise Office receives and investigates noise complaints from .local citizens and
all other sources. During the fourth quarter of 1994, the Office received a total of 292 complaints from
local' citizens, a 58.2 % decrease from the 698 complaints received during the previous quarter ands
decrease of 47.7% from the 559 complaints 'received during the same quarter of 1993. Figure 3 shows
the local geographic area distribution of the quarterly telephone complaints.

U_rxtate on ~//552 All-Cargo Operations at lohn Wayne Airport - A final draft will be
prepared and presented to the Aizport Commission in November and to the. Board of
Supendsors on December 7, 1994. An explanation was given on the two cargo operation'
alternatives studied and presented in the environmental document:
a. Use two of the existing 39 Class A ADDs for the two cargo operations.
b. Create two new Class A ADDs for cargo operations.
The ~ discusses potential amendments to the Phase 2 Access Plan regarding cargo
operations.
The two cargo operators on the new entrant waiting list are LIPS and Federal Express.
Martin South asked if there will be "bonus" flights for quiet operations? John answered "No".
Status of the Accelerated Acoustical Insulation Progrmn in SanTM Ana Heightq - The County
has received an FAA grant to fund up to $8 million for acoustical insulation improvements
of eligible units in Santa Ama Heights. There are 509 eligible units. 127 units have expressed
interest in voluntary participation. The owners of 36 units have signed.contract documents
with the County to receive acoustical .insulation improvements and give the County an
avigation easement.
Phase 2 Access Plan Changes to the Affiliate Policy - In October 1994, the Board of
Supervisors approved modification to the Affiliate Policy. These changes will permit Air
Carriers and Commuter Carders to utilize their joint capacity during individual Plan Years.
Reno Air and American Airlines are the first carders to take advantage of this opportunity
and have formed the first "Associated Operating Gkoup".
Installation of Permanent Remote Noise Monitoring Stations - The installations of new Remote
Monitoring Stations 22 and 24 were completed several months ago. Remote Monitoring
Station 21 installation is expected to be complete in early 1995. JWA plans to decommission
and remove Remote Monitoring Stations 4 and 5 later in 1995, as appro/zed earlier by the
Board of Supervisors.

Dear Ms. Westfield,
As requested, we have reviewed the referenced quarterly report 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: .~

Referring to Figures 1 and 2, the average annual CNEL at station.
M7 was 56.1 dB for 1994 based upon data for the 4th quarter. This
is 0.6 dB lower than the average annual CNEL of 56.7 dB for 1993.
(NOTE: The noise contours for John Wayne Airport are based on
average annual CNEL values measured at each remote monitoring
station.).
It should be noted that the average annual CNEL is skewed by a
lack of data for the entire 1 st, 2nd, and 3rd quarters, as well as 26
days throughout the 4th quarter. This is because remote monitoring
station #7 in Tustin was temporarily removed from service due to
building construction at the location.'

Referring to Figure 2, there does not appear to be any correlation between the average
number of noise complaints received from the Tustin/Orange area and the average
quarterly aircraft CNEL or the average quarterly number ofjet operations. As indicated in
the figure, the number of noise complaints was significantly lower in the fourth quarter of
1994 than in the third quarter even though the total number ofjet operations increased.
Referring to both Table 2 and Figure 2, the number of complaints also does not. correlate
with the percentage'of noisier aircraft (Class A and AA) landing at the airport. Between the
third and fourth quarters of 1994, the number of complaints decreased significantly though
the percentage of noisier aircraft remained the same.
As indicated in Item 1, above, the annual average CNEL measured at station M7 was 56.1
dB based on information for 1994. 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
(Reference 1).
AIRCRAFT NOISE CONTOURS
In 1988, an exterior aircraft noise monitoring effort was conducted throughout the City of Tustin
by the John Wayne Airport Noise Abatement Office and by J. J. Van Houten and Associates, Inc.
(Reference 1). Aircraft-generated single event noise exposure levels (SENEL's) were measured at
twelve locations in Tustin over a five month period.
As a result of this effort, noise contours were developed for John Wayne Airport as they impact
the City of Tustin. Although the shape of the contours does not change (since flight tracks are
fixed), the value of the noise contours does change with different levels of operations at the
airport and different mixes of aircraft.
Figure 3 provides the approximate location of the John Wayne Airport noise contours for 1990
based on measurements obtained at monitoring station M7 throughout the year. Referring to the
figure, the community noise equivalent level (CNEL) ranged from 53 to 59 dB in the City of
Tustin, with a CNEL of about 55 dB at station M7.
Based on data for the fourth quarter, the annual average CNEL at station M7 was 56.1 dB in
1994. The existh!g and future Phase 2 contours (based on 1994 data) are provided in Figure 4.
Referring to the figure, it is estimated that in 1994 the aircraft-generated CNEL will range from
54 to 60 dB. This is well below the City, County, and State criteria of 65 dB for residential areas.
USE OF QUIETER AIRCRAFT AT JWA
As requested, we have analyzed the correlation between the increasing use of quieter aircraft at
JWA and the cl/ange in CNEL within the City of Tustin. 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 ltl aircraft since the early 1970%.

J. J. VAN HOUTEN & ASSOCIATES, INC.
CITY OF TUSTIN

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 1993 and the fourth quarter
of 1994. Also provided is the measured average quarterly CNEL at monitoring station M7. 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 5, the percentage of quieter Class E aircraR using John Wayne
Airport in the 3rd and 4th quarters of 1994 was higher than that used throughout 1993 (about
31%). There was a decrease in Class A airerah that was offset by an increase in the use of the
quieter Class E aircraft. With this decrease in noisier aircraft the weighted average quarterly
CNEL decreased slightly.

Dear Ms. Westfield,
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:
1. Referring to Figures 1 and 2, the average annual CNEL at station
M7 will be 56.2 dB for 1995 based upon data for the 1st and 2nd
quarters. This is 0.1 dB higher than the average annual CNEL of
56.1 dB for 1994. (NOTE: The noise contours for John Wayne
Airport are based on average annual CNEL values measured at
each remote monitoring station.) It should be noted that the
average annual CNEL is skewed by the lack of data for 51 days
throughout the 1 st and 2nd quarters, including most of May.
CITY OF TUSTIN
Project File: 2306-91
2. Referring to Figure 2, the number of noise cOmplaints has increased slightly each quarter
since the 4th quarter of 1994. This may correspond with the slight increase in average
quarterly CNEL each quarter during the same period. However, while the number of
complaints has consistently increased each quarter since the 4th quarter of 1994, the
average quarterly number of jet operations has varied significantly. While jet operations
increased during the 1 st quarter of 1995, they decreased in the 2nd quarter..Thus, there
does not appear to be any correspondence between the number of complaints and the
average quarterly number of jet operations.
3. As indicated in Item 1, above, the annual' average CNEL measured at station M7 will be
about 56.2 dB based on information through the second quarter of 1995. This is slightly
less'than the 58 dB that was estimated for the station in the referenced aircrat~ noise
impact study for the Phase 2 Access Plan (Reference 1).
AIRCRAFT NOISE CONTOURS
In 1988, an exterior aircraft noise monitoring effort was conducted throughout the City of Tustin
by the John Wayne Airport Noise Abatement Office and by J. J. Van Houten and Associates, Inc.
(Reference 1). Aircraft-generated single event noise exposure levels (SENEL's) were measured at
twelve locations in Tustin over a five month period.
As a result of this effort, noise contours were developed for John Wayne Airport as they impact
the City of Tustin. Although the shape of the contours does not change (since flight tracks are
fixed), the value of the noise contours does change with different levels Of operations at the
airport and different mixes of aircraft.
Figure 3 provides the approximate location of the John Wayne Airport noise contours for 1990
based on measurements obtained at monitoring station M7 throughout the year. Referring to the
figure, the Community noise equivalent level (CNEL) ranged from 53 to 59 dB in the City of
Tustin, with a CNEL of about 55 dB at station M7.
Based on data through the second quarter, the annual average CNEL at station M7 was 56.2 dB
in 1995. The existing and future Phase 2 contours (based on 1995 data) are provided in Figure 4.
Referring to the figure, it is estimated that in 1995 the aircraft-generated CNEL will range from
54 to 60 dB. This is well below the City, County, and State criteria of 65 dB for residential areas.
USE dF QUIETER AIRCRAFT AT JWA
AS requested, we have analyzed the correlation between the increasing use of quieter aircraft at
JWA and the change in CNEL within the City of Tustin. 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
J. J. VAN HOUTEN & ASSOCIATES, INC.
CITY OF TUSTFN
Project File: 230691
each class of aircraft that used the airport between the first quarter of 1994 and the second
quarter of 1995. Also provided is the measured average quarterly CNEL at monitoring station
M7. 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 a'lrcrafi types.
Referring to Table 2 and Figure 5, the percentage of quieter Class E aircraft using Joh~ Wayne
Airport was higher in the 2nd quarter of 1995 than in the 1st quarter (about 33%). This increase
in Class E aircrat~ was offset by decrease in the use of the noisier Class AA aircraft. However, the
- percentage of noisy Class A aircraft has. steadily increased since the 4th quarter of 1994. With this
increase in noisier aircraft the weighted average quarterly CNEL has also increased.
If you have any questions, please contact the undersigned at 714/476o0932.
