the Manager of Airports to do the following:
1-) .Conduct airport noise meetings with the • resi-dents living around .'
Buchanan Field. and hold those meetings in the local communities.:

•residents"-of''.Concoid '•and. Pleasant -Hill: 'Both meetings weie.•held,..-.
in :the evening, in the local communities, and were very well
publicized to 'assure the best opportunity for public attendance
and response . The master plan/part. 150 noise study consultants
were present and had on display both general aviation and
commercial traffic flight track maps . f-or Buchanan Field. Public
; test imony was. taken and' specific •.additional areas of aircraft
over flight concerns were marked on 'the maps. The consultant :has
revised the flight track maps to incorporate this input.
WHY ARE NOISE COMPLAINTS UP:
-----------------
.There . is no. one answer. to this que�stiori. The. AAC.'and airport
management have' been working very hard for' many' years to 'reduce
Airport Noise Issues cont.
the noise levels at Buchanan Field and for the most part these
efforts have been .ve•ry successful . As -has been shown by every
noise study done in the .past few years, the 60 and 65• CNEL''noise
contours for Buchanan Field continue to shrink. The flight
operations activity level at the airport also continues to
shrink. Airport operations are down dramatically from the high
in 1978 and are currently running at about a 1965 rate. The mix
of aircraft currently operating from the airport include many new
quiet technology aircraft and the overall fleet is quieter than
In the past. Yet our noise complaints are up over 400% from 1985
levels.
The attached "Noise Abatement Report" from the public works
director and the manager of , airports contains a comprehensive
list of noise' abatement actions, taken before and after the- sun
valley- 'accident, that have been implemented by the AAC and
airport staff. The AAC agrees completely with this report and
the conclusions it reaches. The AAC recommends that members of
the Board study the report carefully as it covers the last few
years of noise complaint activity in a historical fashion.
It is very' true that much of the -noise- complaint activity now
being experienced is due''to both dramatically heightened citizen
awareness and exploitive media attention being given to the '
negative aspects of aviation. The direct -result is much higher
visibility for the airport. '. The AAC feels that these high levels
of publ-ic awareness -and. airport visibility are not; likely to
diminish. Current Congressional hearings -on .thi.s. very subject
confirm nationally the .magnitude of reactions- we .are experiencing
locally. :
The AAC feels 'strongly that the county and communities adjacent' '
to Buchanan Field must begin ' to exercise more prudent' use of
: . :their:• zoning- powers. as -,they relatd• .to future.-deve1opmerxt..:axound:-'-.
' . . t'he. airpo'rt..'.. •The -recent County General P.lan...amendment that
allows high density .residential development in. the Pacheco area
is a good example of what is happening in the' county that results
in additional noise complaints. The county must begin to
coordinate among its various departments and agencies on issues
of .developmerit near the. airport. The quality of life for future
res'i.de.nt�s 'arkd.. the •continued . utility, of the airport hang in the-
bala.nce. It is clear"to' .t'he' AAC that the .community development
. department and' the- county'.planning- commission have little
. knowledge of, or concern for, the public noise issues around
Buchanan Field. - This lack of concern and coordination with the
ALUC and AAC -by these agencies before making recommendations to
the Board of Supervisors is 'producing an unnecessary disservice
to the Board and the residents.-of this county. • It is the AAC's.
opinion that the Board of- Supervisors should direct the community'
development depar.tment and the county plarining commission to

refer all projects and general plan amendments that fall within
the ALUC's' sphere of. influence to the ALUC and. the .AAC '.for .
comment -before sending their recommendations -to the Board. This
should be a matter of county policy. It is further felt that
once the county has established a policy for development around
the airport it will then set a positive example for Concord,
Pleasant Hill, and Martinez to' follow.
Visual noise, or soft noise, is a major problem at Buchanan
Field. The vast majority of the noise complaints received are
well outside of the airport 60 CNEL noise contour line. The AAC
has asked the Board to commission a new master plan and along
with it an extensive FAR part 150 noise study. The AAC has asked
the consultant to develop a standard for visual, or soft, noise. .
This 'is a very difficult assignment and the Board should be aware
that the noise problems we are . experiencing' are common nation-
wide. When the FAR part 150 noise study for Buchanan Field is
complete in March of 1988, it will be only the 7th to be done in
California and only about the 20th in the nation.
Most airports now .have substantial community noise problems well
outside their 'hard noise 65 CN.EL 'contours . The recent DSM
Development. debate • contained an argument by the developer 's
consultant. that since their project was outside the 60 CNEL
contour, there was not a noise problem and therefore the ALUC and
the' AAC were opposing the project on emotional grounds rather
than rules'.or .regu•lations.. The position of -the ALUC .and the -AAC •
that high density multi-family residential development. 1's not
appropriate under or near the airport traffic patterns .is taken
after . careful• evaluation' of hundreds of.•Ver-ifted noise complaints'
and numerous' public 'testimony meetings -held. by '"the' AAC at -the
direction o.f ' the Board 'of. Supe•rvi-sors. '
. I.f.•currently;. as...was argued.,.by D�&M�and..appa pntly :accepted by the
Board-, • ahy''developzaent 'up to the : 60--CNEL.. contour .Line
acceptable and• 'd•oes not •.constitute=..a noise problem•,. then the AAC•
must ask the Board if they are now. d.irecting the AAC and airport
staff to legitimately ignore all noise complaints outside the .
contour line . Otherwise, the AAC feels that it is being placed
in an untenable position on this issue.
NOISE ORDINANCE:
In August of 1986 the AAG sent to• the Board a recommended noise
ordinance for' Buchanan Field Airport', after much work by airport
.staff, • a. great deal of study .by the AAC., and input from. a noted . .
consultant.- in -the -field. ' As- you may recall •the FAA rejected that
ordnance on' th'e grounds that we ,did net 'have' sufficient. .
3
Airport Noise Issues cont.
documentation to support our restrictions and position,
Indicating that an -FAR Part. 150 noise study would constitute .
sufficient documentation. The 'AAC. then recommended- to the Board
that such a study be incorporated with the new airport master
plan. We are currently about midway through this study.
The AAC asked FAA representatives to attend our August 1987
meeting to review their procedures for adopting a noise
ordinance. Our 150 noise study consultant was also present to
ask questions and give a progress report to both the AAC and the
FAA. The AAC feels that when the 150 noise study is complete and
the FAA is presented with our new noise ordinance to review, we
will receive a prompt response.
The Board- has asked the AAC to implement noise abatement action
Items as soon as sufficient data is available -during the .study.
The AAC has asked the consultant to take all of the Buchanan
Field flight tracks and overlay them on one 8 1/2 X 11 sheet for
distribution to all agencies that deal with development around
the airport. This has been completed and is now being printed.
The AAC has established a Noise Task Force to meet with- and. aid
the - master plan/150- noise study consultants.: Two meetings of
this group have been held with'approxima.tely five more scheduled.
The consultants are free to call this group together any time .
they need community input.
RECOMMENDATIONS:
: .1) The Board of Supervisors •should direct, the community
devel.opmen.t department.'and' the 'county planning- commission to
:re+fer' a.11: priojects�: zoning.::ctiange :proposals. and general plan
amendment, proposals ':that' fall•' within the.-ALUgI s' sphere o.f.
influence to the AWC: and the A►AC for ' comment
-prior to making

2) The Board of Supervisors should. take a leadership role in
development planning around the airport . This means assuring
consistent coordination among all the. agencies having .planning
and action responsibilities within the ALUC sphere of .. .. '
influence .
3) The Board must acknowledge that- there. is a very real 'aviation
noise impact on residents living'-outside the hard noise
contours of the airport. The newly developed composite flight
track map is a 'good indicator .of where problem areas have -and '
can occur•. It.. As '-the AAC!.s: position that the Board should .

development under or near these. flight tracks. The quality of .
life -of residents who live" and .work around the airport is very
important to •the long term utility of the airport.
4 ) Residential development that is allowed within the ALUC sphere
of influence should have the following conditions imposed as
requirements for approval:
A) DISCLOSURE STATEMENT - advising prospective buyers that the
property is located near an airport and subject to aircraft
over flights.
B) AVIGATION EASEMENT - be 'entered on the deed for the property.
C) TITLE 25 OF THE CALIFORNIA ADMINISTRATIVE CODE - builder
must be required to comply with the requirements of Title
25 even though the subject development may fall outside of
the airport hard noise contour. This would require an
acoustical .study of the project and 45 dba interior noise
levels.

FROM: J. Michael Walford, Public Works Director
SUBJECT: Noise Abatement Report
The. Board of Supervisors ha-s asked the Aviation Advisory. Committee-and the
Manager of Airports to prepare a report as to 'the reasons that noise
complaints are up. Historically, the Aviation Advisory Committee has worked
as a community compatibility and noise abatement committee as one of its
first goals. Prior to December 23, 1985, a significant list of noise
abatement efforts had been implemented. These include:
1. Raised traffic pattern altitude from 800 to. 1,000 feet 'for small
aircraft and from .1,200 feet td- 1,500 -feet-- for large :aircraft..
2. Established the use of -Runway 32R as the noise abatement
preferential runway and worked with the FAA Control ..Tower to
encourage.operators of noisier aircraft to depart on 32R.
3.- Established a -series of preferential traffic patterns specifically
designed-to avoid .noise sensitive areas.- ' .
4. Establ'i-shed 'an airport. newsletter that specifically incl'uded .nois.e
abatement s.ubjects: This newsletter ' has developed into- -a
distni-bution of a,pproximatel-y- 1',000 -interested-.parties- and airport
'users
•5. Periodically met with pilot groups .and flying' elubs to advise them
of noise problems.
6. Met regularly with FBO administrators• to .enlist the help -of their
instructors :and'•pilots .relat ive to noise abatement.
7.- - '.Establ i-shed isppecial noise abatement traffic' patterns for
helicopters.
8. Made. onsite observations. of.noise sensitive areas- relative to the
type of -aircraft responsible for noise complaints and the manner
in which they are. flown:'
9.-. PuPlished •in Federal Airports Facilities .Directory "Noise
sensitive area, practice noise abatement (fly quiet) procedures."
•10: Prohibited touch and go landings between the hours. of 10':00 p:m.'
and -6:00 a.m.
11. Have requested VASI's for Runway- 32L.
12. Raised all VASI 's to maximum angle of descent.
13. Established unofficial upper limit of 850 based aircraft for'
Buchanan Field Airport.
14. Includes noise abatement discussions as a monthly topic at all AAC
meetings.
Since the accident at Sun Valley Mall , a number of other steps in activities
relative to community compatibility have been initiated. These include:
1. Initiated a safety study by' Flight Safety Institute of Sacramento.
2. Put a new Ordinance in place which includes -a variety of noise
abatement and safety issues.
3. Commissioned extensive noise and environmental studies. . Mestre
Greve. Associates. prepared in-depth noise .studies for the ajrpor.t
in anticipation of - Pacific Southwest Airl.ines . service.•
McClintock, Becker.& Associates did a:'major environmental 'investi-

The airport monitors up' to 8. hours/day at 'locations specifically
requested by the airport noise consultants, as well' -as at random
locations in. 'noise sdnsit-ive neighborhoods. This. monitoring is
done utilizing •an airport employee on'. the site identifying all
aircraft that trigger. the nois.e monitor.
9. TFe airport h'as'. increased its programof inviting people •impacted
-to the airport"to inform them of safety' programs and efforts being
made to minimize the impact of the airport on the surrounding
community.
3 .
10.' The airport is-analyiing monthly obmplaints in considerable detail
to evaluate .possible patterns that 'wily lead to corrective
measures.
11. The airport conducted a meeting with all bay area helicopter
operators, including military, relative to noise problems in the
surrounding area. The result of this meeting included new
-transient helicopter traffic patterns which kept helicopters over
the nonpopulated areas. Further, agreement was reached for
maintaining altitudes of 1 ,000 feet or greater over all
residential areas in central Contra Costa County.
12. The airport staff has responded in writing to 1,000 citizen
complaints. The airport has written .to approximately 100 pilots
that have caused noise complaints and talked to approiiimately..200
additional pilots. * The airport is dedicating approximately 40-
50 hours per week in staff time to noise issues' including time
spent in the field monitoring aircraft noise.
13. Additional environmental and noise studies have been completed
relative to an airport Access Plan to limit scheduled airline
service from Buchanan Field Airport.
14. . Implemented an Interim 'Ai'rline' - Access 'Plan which wily limit .the
number of scheduled -aircraft that -can operate from Buchanan Field
Airport until such time. as: the master plan and the FAR - Part 150
Noise Study are completed.
15. -.'Required additional noise studies of Cal West Airlines 'to ev.a:luate
their.. proposed scheduled -service. between. the hours o.f 6.:00 a.m.:
.and 1:00.'a.m..
There-'appears to be a. number of 'factors involved in 'the dramatic increase in
-noise. comp.T•aints at :Buchanan.-Fi-eld Airpor.t. . These -include::.
. 1. ' '•'The :orig'inaI • 'Pa-c-i-fic. ' Southwest.':Aiirlines •(PSA') : applicatfon' -fort-
service at -.Buchanan •Fi.el-d -Airport 'occurred in Octo.her .and
November, 1985. Shortly thereafter, an' organized citizens group
opposed PSA.serv-ice.' Once this information became a- publi-c issue,
the complaints began increasing in November and December.
2. On December 23 ' 1985• an 'aircraft' crashed into Sun Valley Mall
Complaints .increased' by approximately threefold through the month
of May.
3. In .May, 1986. PSA began scheduled service out of. Buchanan Field
Airport: Noise complaints again increased- by approximately three
times•.. Approximately 20% of the total complaints were directed
-against Pacific Southwest Airlines.
4
4. • ' During. this entire time period, the airport. was- experiencing an
extremely high level of visibility in the news media. There was
continuing discussion regarding the Mall accident, as well as
articles relating to PSA. The citizens opposing PSA service
continued to be quite active.
5. The Aviation Advisory Committee and others actively solicited
input from citizens concerned about airport activities. The AAC
held a large number of meetings with pilot and citizen groups
relative to airport operations. This developed a substantially
heightened awareness of the airport and its activities.
6. Aircraft operations by PSA have been substantially as expected
prior to startup. ' During all public meetings, the AAC, the
airport staff and the consultants estimated that PSA would operate
over -Pleasant Hill (our •most sensitive community) between 5% and:
10%-of' the time according to 'the wind data we had available. PSA
to date has operated over Pleasant Hill approximately 5.6% of the
time.
During the PSA startup investigations, it was assumed that the
real issue for PSA was that of noise. After PSA actually -began
service, it . became apparent that: the visual.'. impact of PSA over
residential areas is more upsetting to some 'of the citiiens than
the noise level. The PSA landings • generate more complaints. than ' . -
take'offs.
7. Because .of- the. substantia•l.l-y -.increased- statistical 'analysis being
maintained- by the airport, it wa's found. that. specific increases in- .
..complaints occur soon' after any major aircraft accident which
-makes high ' level news media coverage..'- 'This .'indluded the E1 '
Ce.rrftos' crash; the 'mid'-air .crash over the -Grand Canyon; and the .
mid-air collision near Oakland. •
''8:. : 'Upon deve.lopmerit of the lnterirti "Airline Access Plan;. a new
.citizens .group :was. formed.. and once 'again .the .airport became a. news
media• topi-c'.. A citizens group- in Pleasant. Hill..:•was 'once .agai.n ..
formed to oppose any increa'ses' in scheduled airline servic•e. ' .Once
again, there were increases in complaints noted.
The following conclusions have been reached by the. Manager .of Airports and
the-.'Aviation Adviso.ry Committee as to -the reasons that noise complaints are
up. The . following list is not necessarily. in any order of priority.
1. A -dramatica-lly heightened -awareness by citizens as to the ,
proximity of the..airport 'has contributed- greatly to • the increase
in- noise compl-ai6ts . • -There is a very. -spe' ci fic and. 'direct
relationship between the Sun Valley Mall accident and an increase .
in complaints... There is .also a direct. relationship between. the
advent of 'PSA• startup.-add. complaints. We have also tracked some
pei^iodic .increases'.:in -complaints to news .media aviation ev.e'nts'.
2. The airport has several. more employees than it did two years ago. '
5
As -a result of getting '•PSA service, the airport has' increased its
staffing to where there is no less than .two people on duty, seven
days per 'week; .6:00 a.m. Ao 10:00 p.m. , and one- person on duty
from 10:00' p.m. to 6:00 a.m. 'Because ' of this higher level of
staffing, the airport is able to handle a much larger number of
direct calls. The airport also is able to' unload the recorder
several times during the day. Once the information is transferred
either from the direct complaint. or from the recorder, it gets
appropriate followup.
3. The airport has developed a much improved followup system and
.recordkeeping program since January of 1986. All of the data is
now in the airport computer system and our internal followup
procedures have been expanded.
An additional change 'that has occurred is that we took all noise
complaints away from the Control Tower. The airport requested
that all complaints be forwarded to the airport office for
processing. The airport further asked that all residents contact
the ai.rport and that the Tower refer all calls to - the airport if
they should receive them. Prior to doing ''this the Tower
complaints were not recorded as separate complaint items.
4. The airport' currently logs all. compla.i.nts even if they are not
totally complete. Prior to' 1986 the airport .only logged those
complaints where people. wanted to make "formal complaints". At
.that time the airport always. specifically asked the question and
frequently .'after .discussing- -the' -Issue of the- 'overflight, . many
citizens decided that -they did not care to pursue the matter any
-further. The ,a.i rport's :current .policy .i s to. log all call-s. 'and
-fill out'-a' form:. The. only •case where the airpo.rt•'will not .treat a
complain ' as legitimate. is where thie caller will not identify
himself.
Cur�^ently- between'15:.and .20X of 'All call s received are cal l:s: .which .
have no relationship' to Bu.c:hana.h. Field Aarpo.rt: These 'incluoe
calls from -as far away- as, Danvi ll a and - Di-scovery- Bay. It also
includes calls regarding airplanes that are flying over out of
Oakland or San - Franci-sco. Recently, for example, the- airport
recorded eight 'complaints against the Concorde which departed .
Oakland.. ' Prior to '1986 these calls . would not necessarily have
been logged.
5. The' Manager of Airports and the Aviation Advisory Committee have
further determined that the residential development occurring in
the Pleasant Hill area directly south of Buchanan Field Airport
has been significant. This' development is still continuing. Many
o•f the homes are on - the hills and ridges .putting them closer to -
the aircraft in .-.the traffic 'pattern . A high ' pe.rcenta-ge' of
co%plaints are coming -from these new .re' sidents..• It should also be
noted that• in the unincorporated areas of the County that
residential encroachment has also occurred to the extent that
these areas are generating new complaints.
6
6. A number of ' citizens have become somewhat pro-active in their
neighborhoods in generating noise .complaints whenever aircraft
pass over their area that they find objectionable. We are able to
identify these areas fairly specifically with the information
contained in our computerized data base.
7. The Manager of Airports and the Aviation Advisory Committee feel
that one of the most significant causes of the higher number of
noise complaints is that of the extremely heightened visibility of
the airport. Also over the past year to two years there has been
a greatly heightened news media coverage on the negative aspects
of Aviation. As to the specifics of the. local area, the airport
is good news reporting and for whatever reason we are frequently
in the newspapers or 'on television. •In addition, 'the Aviation
Advisory Committee has. been holding various public meetings, .
including public hearings on the issues of noise. In all of our
public . dealings we are specifically making the issue to the
citizens around the airport to call us whenever they have any kind
of noise complaint. In other words, we are in fact soliciting
noise complaints.
The noise levels have -been shown to- be continually decreasing. Our current
ongoing noise study will be showing that . it has .-'decreased due to our noise.
abatement efforts even 'over the 'past'-year. . It is significantly down .from
the earlier period of five to- seven years ago. In addition, the aircraft
traffic levels continue to decrease out of the airport. This is not
some specific to Buchanan Field Airport but- is' in line- with the trend
of- all tower control- General Aviation airports.- We are currently operating
at.approximately. our. 1965 air traffic level : -•.It should also be: noted that
with very: few' exceptions; all airplanes 'are .fly!.ng i•n..a legal-manner and in
accordance:with. Federal Or Regulations. . Whenever' we-have. reason to believe .
that an aircraft is .not operating in accordance -with. Federal Air.• Regula-
tions or whenever the'.caller .alleges "reckle.ss- flying".-we always refer these...
inatters. .to .'the'FAA.'
