DISCUSSION
The Community Development Department has continued to monitor
airport issues and attend all relevant meetings. Since the last
• Airport Status Report to the City Council on October 7, 1991, staff
has:
* Attended a meeting of the Noise Abatement Committee;
* Coordinated a review of Coalition for Responsible Airport
Solution (CRAS) activities by the City's CRAS
representative Kathy Weil;
* Met with members of the Federal Aviation Administration
(FAA) task force regarding MCAS Tustin;
* Reviewed the latest John Wayne Airport Noise Abatement
Quarterly Report by the City's noise consultants.
The following items summarize the most significant local airport
activities that have taken place during the past four months.
The Orange County Cities Airport Authority (OCCAA) - The OCCAA
canceled its October, November, December, and January meetings due
to lack of quorum or agenda. The next meeting is scheduled for
February 19, 1992.
Noise Abatement Committee - Staff attended the quarterly Noise
Abatement Forum meeting on November 21, 1991. While the issues
discussed at the meeting did not directly concern the City of
Tustin, the issue of noise complaint form processing is noteworthy.
According to Noise Abatement Office staff, the new procedure in
which only multiple, warranted, and unusual complaints are
forwarded to carriers is working well and has greatly improved
efficiency.

Coalition for Responsible Airport Solution (CRAS) - Kathy Weil,
our City representative for CRAS, has prepared the attached report
on the most recent developments for CRAS.
FAA Task Force - On January 22, 1992 Community Development staff
met with members of the FAA task force to discuss their mission in
reviewing and analyzing the Tustin MCAS as a potential overflow
public aviation site.
The committee members stated that they believed there were
potential conflicts in using MCAS as an overflow site due to its
proximity to John Wayne Airport and the amount of existing air
traffic in the area. Their mission is to only report their
findings and not to make a recommendation to the FAA, although it
appeared as if they thought the site was infeasible. Staff
reinforced the 'City's position on discouraging the reuse of the
MCAS -Tustin as either a general, commercial or overflow aviation
site and also discussed the city's position on retaining JWA's
existing approach patterns along the SR -55. Staff explained the
base reuse/specific plan process we are undertaking. The FAA
appeared not to have any knowledge of our agreement with the
Marines to prepare such a plan. We requested a copy of their
report when it was complete.
Airport Noise Abatement - In November, 1991, J.J. Van Houten and
Associates, Inc., Tustin's noise consultants, prepared a review of
County -prepared John Wayne Airport Noise Abatement Progralu
quarterly report for the 2nd quarter of 1991. A copy of their
report is attached.
From 1990 through the second quarter of 1991 there has been a 2.5
dB increase in aircraft -generated Community Noise Equivalent Level
(CNEL) at monitoring station M7 (On October 1, 1990, remote
monitoring station M5 in Tustin was renumbered as M7). During the
last two quarters of 1990 and the first two quarters of 1991, the
average number of commercial jet operations has increased and then
decreased slightly; the average quarterly CNEL values measured at
station M7 have increased; but the number of quarterly noise
complaints for Tustin/Orange increased, then decreased dramatically
and then increased. Again, this strongly implies that people react
to Single Event Noise Equivalency Levels (SENEL) rather than long-
term noise exposure (CNEL). Based on data through the first
quarter, the annual average CNEL at station M7 will be 57.5 dB in
1991. It is estimated that in 1991, the aircraft -generated CNEL

will range from 55 to 61 dB. This is below the City, County, and
State criteria of 65 dB for residential areas.
A request has been made of the consultant to analyze the
relationship between changes in CNEL and the number of quieter
aircraft being put into service at John Wayne Airport.
CONCLUSION
Because the issues discussed above are of considerable importance
to the City of Tustin, the Community Development Department will
continue to monitor airport issues unless otherwise directed by
•Council.

RE: CRAS MEETING OF JANUARY 23, 1992
Very quickly, the enclosed newspaper clipping (report by Supervisor Tom Riley) about Riley's ap-
pointment to the SCRAA (Southern California Regional Airport Authority) explains recent develop-
ments in Orange County's airport thinking. This is very good news! CRAS' consultant, Bill
Meacham was partially responsible for that move. He has also been very active in convincing
Anaheim to withdraw from Ken Delino's group OCCAA. As of our meeting he was about a whisker
away from making that happen. If he's successful, we will have diluted OCCAA considerably. It
should then be a lot easier to convince other cities that Ken is no longer a player in the airport busi-
ness.
All this activity has diluted CRAS' treasury though so we have been asked to request that when you
are planning next year's budget you include a membership renewal for CRAS of $1000.
Our meeting schedule has been changed to bi-monthly, with our next meeting in March. Our Annual
Meeting will probably take place in May.

:ties Can Help Voice Local Aviation Needs at Regional Level
Cooperation among
neighbors is crucial
when planning for and
expanding airport
facilities.
By THOMAS F. RILEY
In the last decade, Southern California
has seen a tremendous growth in the
number of new residents and busi-
nesses. Orange County alone averages
more than 48,000 births each year. With
this growth has come a significant in-
crease in the demand for services, includ-
ing transportation.
Although most public attention has
been focused on our overburdened
streets and highways, the challenges
presented by a rapidly growing demand
for air travel have moved to the top of
Orange County's transportation agenda.
The future requires a better coordination
between airports and ground transports -
Lion in conjunction with the application of
new technology, such as the high-speed
train and tilt -rotor aviation.
As Southern California continues to
grow, the traditional approach of cities
and counties setting their own priorities
in isolation and discounting the need to
participate with their neighbors is quick-
ly dissolving as resources and -tax reve-
nue decline and the needs of the com-
munity change. Strict adherence to
traditional boundaries diminish as re-
gional solutions are required to meet
increasing demands. This, however, is
not to say that local participation will
decline.. it will always remain a vital part
^t decision-making process.
very nature, commercial avia-
.his country frequently involves
and competing interests, each of
which must be recognized and offered a
balanced representation in de-
cisions relating to airport de-
velopment and use. The alter-
natives and solutions must be
identified carefully, if we are to
avoid simply aggravating the
fine balance between regional
transportation and local con-
trol.
Orange County continues to
take proactive steps to improve
transportation. It has approved several
tollway projects and improved efficiency,
planning and project implementation by
creating the Orange County Transporta-
tion Authority.
In addition, more than 346,000 Orange
County residents voted to pass Measure
M. which provides $3 billion over 20
years for freeway, street, road and mass -
transit improvements and affirms the
public's desire to improve transportation
alternatives on a regional basis.
Our success locally to increase capacity
at John Wayne Airport was the direct
result of hard work and cooperation
among local parties. This effort included
cities and community groups that are
closest to the issues and which have the
power to resolve them. It did not involve
the intervention of a geographically and
politically distant state or federal agency.
To preserve local control and avoid
intervention, we must continue to ensure
that Southern California needs are ad-
dressed locally.
Our achievements at John Wayne
Airport are impressive. They were possi-
ble because the Board of Supervisors has
been able to exercise its discretion to
appropriately regulate airport noise and
work with the various interest groups to
reach common goals.
The improvement project at John
Wayne Airport not only increased capac-
ity, but provided new infrastructure and
transportation improvements.
Even with this progress, the region by
2010 will fall short of meeting the public's
air travel needs by an estimated 15
million passengers a year. The size and
facilities at John Wayne Airport preclude
its ability to meet this need, or the
increasing demand for international trav-
el. The shortfall is why planning and
project implementation are required now
on a regional basis. We must regionally
improve capacity at existing airports,
study new technology (including the
high-speed train and tilt -rotor aviation to
augment short -haul demand) and, as
appropriate, locate and develop new fa-
cilities to provide more flights and inter-
national service for the region.
The county has established the Orange
County Regional Airport Task Force,
with representation from the Orange
County Division, League of California
Cities, to serve as the supervisors' focal
point for aviation planning. Though a
suitable site to initiate master planning of
a new airport is not available within
Orange County, exciting alternatives are
close at hand. The Defense Department
has announced closure of Norton and
George Air Force bases in San Bernardi-
no County and several airports in
Southern California will begin expansion
projects within the next few years.
Locally, El Toro continues to be a topic
of discussion. But the idea of joint use is
neither practical nor compatible with the
Marine Corps mission. The recent events
of Desert Storm demonstrate the impor-
tance of the base to our national defense.
To ensure local interests are repre-
sented, the County Board of Supervisors
has recently joined the Southern Califor-
nia Regional Airport Authority
(SCRAA). The authority includes repre-
sentatives from San Bernardino, Los
Angeles and Riverside counties, as well
as from the city of Los Angeles. Its
primary purpose is to coordinate aviation
issues on a regional basis to meet air
passenger demand.
Aviation continues to be an important
local issue for the businesses and resi-
dents of Orange County that depend on
air transportation, and for the various
communities impacted by aircraft noise.
It is through participation in SCRAA that
Orange County will speak with one voice
and enable the Board of Supervisors to
serve as the conduit for communication
between regional interests and the local
community.
The best approach to many of the
regional issues, including aviation, that
face counties and cities requires coopera-
tion with our neighbors—and creative
solutions on a regional basis. Regional
benefits have already been attained
through such joint ventures as the Santa
Ana River Mainstream project and the
Four -County Rail Plan.
Without question, the next few years
will bring many hard decisions regarding
airport expansion projects and the siting
of a new airport in Southern California.
Our best hope for timely action rests on
working with our neighboring cities and
counties to identify, plan and provide
sufficient airport facilities that benefit.

Subject: Review of John Wayne Airport Noise Abatement Program Quarterly
Report, 2nd Quarter 1991
Reference: 1. "Data Evaluation and Aircraft Noise Impact Study for the City of
Tustin," J. J. Van Houten and Associates, Inc., January 8, 1990
2. "Noise Abatement Program Quarterly Report for the Period:
April 1, 1991 through June 30, 1991," John Wayne Airport
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:
1. Referring to Figures 1 and 2, the general trend from 1990 through the first
quarter of 1991 was an increase in aircraft -generated CNEL at remote monitoring
station M7. Based upon data for the 1st quarter, the average annual CNEL at
station M7 is 57.5 dB for 1991. This is a 2.5 dB increase over the average annual
CNEL of 55.5 dB for 1990. (NOTE: The noise contours for John Wayne Airport
are based on average annual CNEL values measured at each remote monitoring
station.)
2. 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 of jet
operations. This strongly implies that people are reacting to the single event
noise levels rather than the long-term noise exposure (CNEL). This is consistent
with the findings of the referenced aircraft noise impact study (Reference 1).
1
3. As indicated in Item 1, above, the annual average CNEL measured at station M7
is 57.5 dB based on information for the first quarter of 1991. 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 through the first quarter, the annual average CNEL at station M7 will be
57.5 dB in 1991. The existing and future Phase 2 contours (based on 1991 data) are
provided in Figure 4. Referring to the figure, it is estimated that in 1991 the aircraft -
generated CNEL will range from 55 to 61 dB. This is well below the City, County, and
State criteria of 65 dB for residential areas.
