Dear Governor and Legislative Leaders:
As requested by the Joint Legislative Audit Committee, the Bureau of State Audits presents its audit report
concerning the accuracy of the San Diego Unified Port District’s (port district) noise-monitoring data, its
process of evaluating airplane noise and flight tracks to respond to complaints, and whether the California
Department of Transportation (Caltrans) uses this information when considering the port district’s application
for a variance to California’s noise standards.
This report concludes that although some community members consider the noise-monitoring system data
suspect, we found the data to be accurate. Contributing to the community’s distrust of the port district’s data is
the cessation of the county of San Diego’s (county) Noise Control Hearing Board, which enforces the terms and
conditions of Lindbergh Field’s variance to the noise standards and audits the port district’s noise-monitoring
data. The port district, San Diego Association of Governments (SANDAG), and the city of San Diego (city) all
share some responsibility for resolving Lindbergh Field’s noise problem. However, the port district’s delays in
implementing sound-attenuation programs, combined with the city’s failure to consistently implement certain
provisions of the comprehensive land use plan, have prevented further decreases in incompatible land use
within Lindbergh Field’s noise impact area. The SANDAG bears some responsibility for not ensuring that the
city’s regulations were consistent with the land use plan. Finally, we found that state regulations limit Caltrans’
role to ensuring that the port district’s noise-monitoring system meets state standards, to granting variances to
the noise standards, and to reviewing quarterly noise-monitoring data for the purpose of assessing progress
towards reducing Lindbergh Field’s noise impact area.
Total aircraft operations at Lindbergh Field are projected to grow at an average annual rate of 2 percent through
2020. At this rate, Lindbergh Field will reach its maximum operating capacity by 2011. Therefore, the
SANDAG, local agencies, and others must band together and decide whether to expand or relocate
Lindbergh Field.

with plan provisions. Although the port district informed the
city of new incompatible land uses in the noise impact area in
January 1997, the city again did not take action promptly. The
city waited until October 2, 2000, to vote to include Lindbergh
Field in its ordinance addressing land development restrictions
near airports. The port estimates that more than 28,000 residents
live within Lindbergh Field’s noise impact area.
The port district receives an average of about 1,000 complaints a
year about the location and intensity of aircraft noise. The most
common complaints are related to loud aircraft overhead and
aircraft disregarding the regular departure route. By law, the FAA
has the sole authority to manage the air traffic control system
and navigable airspace in the United States and to establish
flight operational procedures. Therefore, the port district cannot
restrict the access of noisier aircraft or dictate the appropriate
departure route and has no authority to resolve these types of
complaints. The port district uses its noise-monitoring system to
determine whether these complaints are valid. Although some
community members consider the noise-monitoring system data
suspect, we found the data to be accurate. However, contributing
to the community distrust is the cessation of public meetings by
the county’s Noise Control Hearing Board (noise board), which
enforces the terms and conditions of Lindbergh Field’s variance to
the noise standards and audits the port district’s noise-monitoring
data. Also, the port district’s Airport Noise Advisory Committee
can improve its interaction with the community.
The SANDAG, port district, and local agencies must consider not
only how to deal with current noise issues, but also how to
handle the projected increase in total aircraft operations at
2
Lindbergh Field, estimated to increase by an average annual rate
of 2 percent through 2020. At this rate, Lindbergh Field will reach
its maximum aircraft operating capacity of 275,000 by 2011. There
have been numerous studies about relocating the airport, but thus
far there has been no final decision regarding the expansion or
relocation of Lindbergh Field.
RECOMMENDATIONS
To further its efforts to reduce the impact of aircraft noise and to
respond effectively to complaints, the port district should
improve its community relations efforts. One possibility is to
establish working groups that include local residents. It also
should continue to work with the U.S. Marine Corps to resolve
noise-related issues at the Marine Corps Recruit Depot.
To fully implement the comprehensive land use plan, the city
should continue to work toward making its planning, zoning,
and building regulations consistent with the plan’s provisions.
For example, it should ensure that it obtains the necessary
avigation easements. In addition, the SANDAG should comply
with the plan requirements for ensuring that the city’s general
plan and ordinances agree with the land use plan.
To provide independent verification of the port district’s noise
information, the county should reactivate the noise board.
To address projected growth in air traffic, the SANDAG, local
agencies, and community groups should determine whether to
move the airport.
AGENCY COMMENTS
The San Diego Unified Port District generally agrees with our
recommendations. The city of San Diego, the county of San Diego,
and the San Diego Association of Governments (SANDAG) also
generally agreed with our recommendations. The SANDAG,
however, disagreed with our recommendation that it and other
local entities should decide whether to relocate the airport. The
SANDAG states that this recommendation is unnecessary because
there are public policies in place to address it. Additional
comments made by each entity and our responses begin on

INTRODUCTION
BACKGROUND
T
he San Diego International Airport at Lindbergh Field
(Lindbergh Field), which opened in 1928, is only three
miles northwest of downtown San Diego and one mile
northwest of the central business district. It is also adjacent to
densely populated communities located west (Point Loma and
Ocean Beach) and east (downtown area). The San Diego Bay and
the Marine Corps Recruit Depot are south and north, respec-
tively. Lindbergh Field is the primary commercial service airport
in the San Diego area. It was the busiest single runway airport
and the 28th busiest airport nationwide in terms of passenger
volume in 1999, with more than 15.3 million passengers. Cur-
rently, more than 25 passenger and cargo airlines operate an
average of 630 arrivals and departures daily. Various state and
local entities monitor and manage noise levels at Lindbergh Field,
in compliance with federal and state regulations.
THE ROLE OF THE CALIFORNIA DEPARTMENT
OF TRANSPORTATION
In 1969, the Legislature directed the California Department of
Transportation (Caltrans) to adopt noise standards, to the extent
allowed by federal law, for the operation of aircraft and aircraft
engines at airports operating under a valid permit. Aircraft noise
is measured using units of A-weighted decibels, a logarithmic
measure of the magnitude of a sound as the average person
hears it.1 The higher the number of decibels, the louder the
sound noise seems. Decibel levels are measured logarithmically,
so each increase of about 10 decibels doubles the loudness that
people perceive. Although airport-related sound measurements
are normally single events, the State’s noise standards are based
on a cumulative average that takes into account the number of

aircraft noise events within a 24-hour day.2 Human response to
noise involves both the maximum level and its duration, so the
cumulative average presents a more accurate picture of noise
exposure and the overall impact of noise on a community.
Figure 1 shows peak noise levels for common events.
The Federal Aviation Administration (FAA) and other federal
agencies measure noise impact using the Yearly Day Night
Average Sound Levels (DNL), which assigns additional weight to
sounds occurring between 10 p.m. and 7 a.m.3 The FAA has
specified a 65-decibel DNL as the lower limit for defining signifi-
cant noise impact on people.
California uses a somewhat different measurement method—the
community noise equivalent level (CNEL), which specifies
65 decibels and weighting similar to the DNL but adds an
additional weighting of about five decibels to flights occurring
between 7 p.m. and 10 p.m.
Caltrans can grant variances to the noise standards to “noise
problem airports” that have incompatible land uses within the
CNEL of 65 decibels. A variance constitutes compliance with the
noise standards even though airport noise levels vary from
established standards. The ultimate goal of the variance process
is to require the airport proprietors to develop and implement
programs to reduce any airport noise impact area to zero. In
January 1975, the San Diego Unified Port District (port district)
applied to Caltrans for its first variance to the noise standards
and has since applied for and received seven variances. It applied
for its eighth variance on August 16, 2000.

which was created by the Legislature in 1962. The city councils

2 A single event is usually measured from the time the sound is heard above the
background sound level to its maximum sound level and then until it is no longer distinct.
Another method for measuring a single event is by using the sound exposure level, which
measures the total sound energy the listener is exposed to during a single event.
3 An additional 10-decibel weighting is added to the measurement of noise events occur-
ring between 10 p.m. and 7 a.m. to account for sleep disturbances and other effects.

THE ROLE OF LOCAL GOVERNMENT AGENCIES
IN SAN DIEGO
The county of San Diego (county) enforces state airport noise
regulations. It reviews and audits the noise-monitoring data
from the port district and reports quarterly to Caltrans on
information pertaining to Lindbergh Field’s noise impact area.
Figure 2 on the next page shows Lindbergh Field’s impact area.
The county delegates these responsibilities to its Noise Control
Hearing Board (noise board), which is composed of industry
representatives and community members. The county designated
Lindbergh Field as a noise problem airport in 1972.
In accordance with state law, the San Diego Association of
Governments (SANDAG), as the airport land use commission,
adopted a comprehensive land use plan to ensure the
development of compatible land use surrounding Lindbergh
Field. The plan requires the SANDAG to monitor the city of
San Diego’s (city) general and specific plans, zoning ordinances,
and building regulations to ensure that they are consistent with
the comprehensive land use plan. The city is responsible—
through its ordinances, regulations, and other policies—for
prohibiting incompatible land use around Lindbergh Field.

THE ROLE OF THE FEDERAL GOVERNMENT
By law, the FAA has the sole authority to manage the air traffic
control system and navigable airspace in the United States and
to establish flight operational procedures. The courts have long
held that federal control over airport use is sufficiently “pervasive”
that it occupies the entire field of regulation. Under the Supremacy
Clause of the U.S. Constitution, federal regulation totally preempts
any attempts by state or local agencies to regulate the use of
airports that are part of the national air transportation system for
environmental purposes, including noise or air quality control.
The only exception to this rule is that airport proprietors can
voluntarily exercise some regulatory authority over airport use
to limit their potential damage liability. This “proprietor
exception,” however, has been held to be an insufficient basis
for state or local agencies to indirectly regulate airport use. For
example, in 1969, the Legislature directed Caltrans to adopt
noise standards that limited permissible noise generated by
aircraft and subjected the violator to a misdemeanor liability
and a fine of $1,000. Relying on the principles announced by
the U.S. Supreme Court in Lockheed Air Terminal, Inc. v. City of
Burbank (Lockheed), the U.S. District Court for the Northern
District of California struck down the limits as violating the rule
of federal preemption in Air Transport Ass’n v. Crotti. In Lockheed,
the U.S. Supreme Court stated that the FAA must balance
considerations of safety, efficiency, technological progress,
common defense, and environmental protection when
formulating rules and regulations with respect to the use of the
nation’s airspace. The U.S. Supreme Court
concluded that the extensive control of the federal
government “seems to us to leave no room for local

Stage 2 and stage 3 designations define the

Incompatible land uses can include schools and
residences. The act also directed the FAA to
administer a program to encourage airports to
11
identify incompatible land uses and to develop noise
compatibility programs to reduce any existing or potential
incompatible land uses.
In its Airport Noise and Capacity Act of 1990 (act), Congress
acknowledged the importance of aviation noise management to
the continued increase in airport capacity. The act also called for
a federal noise policy to reduce the number of uncoordinated and
inconsistent community-level restrictions on aviation that could
impede the national air transportation system. Moreover, it con-
cluded that local interest in aviation noise management should be
considered in determining the national interest, and that more
advanced aircraft technology could alleviate community concerns.
Congress also directed the transportation secretary to establish a
national aviation noise policy by July 1, 1991. The policy would
phase out aircraft certified by the FAA as stage 2 and require that
essentially all civil subsonic turbojet airplanes with a maximum
weight of more than 75,000 pounds comply with its stage 3 noise-
level standards after December 31, 1999.
SCOPE AND METHODOLOGY
The Joint Legislative Audit Committee requested that the
Bureau of State Audits (bureau) examine the accuracy of the
noise-monitoring data that the port district reports to Caltrans.
The bureau also was asked to evaluate Lindbergh Field’s noise-
monitoring and flight-tracking system and the port district’s use
of that system to respond to complaints. The bureau was asked
to determine the extent to which Caltrans monitors the port
district’s noise complaint process. We found that state
regulations limit Caltrans’ role to ensuring that the port district’s
noise-monitoring system meets state standards, to granting
variances to the noise standards, and to reviewing quarterly
noise-monitoring data for the purpose of assessing progress
towards reducing Lindbergh Field’s noise impact area.
To obtain an understanding of the laws and regulations governing
airport operations, we reviewed federal and state laws, as well as
relevant court cases. We also interviewed management and staff at
the port district, Caltrans, and the county.
To obtain an understanding of the variance process, we reviewed
state regulations. We also spoke with Caltrans staff to clarify our
understanding and to determine whether it considers noise
complaints when issuing variances.
12
To determine the accuracy of information reported by the port
district in its application for a variance, we reviewed the terms
and conditions of the variance as well as relevant data demon-
strating how it met the terms and conditions. We reviewed
federal documents as well as those from the port district and the
city’s Historical Resources Board. We also made inquiries of port
district and the San Diego Unified School District staff. Further,
we examined the quarterly noise reports and noise contours
produced by the port district from 1996 to March 31, 2000.
To determine the county’s role in monitoring the port district’s
compliance with state airport noise regulations, we reviewed
local policies and state regulations. We also interviewed the
county’s noise control officer.
To determine if local entities were adhering to the requirements
of the city’s comprehensive land use plan, we reviewed state and
federal regulations regarding land use and city ordinances and
internal policies. In addition, we interviewed management and
staff of the port district, the city, and the SANDAG.
To obtain assurance on the accuracy of the port district’s noise-
monitoring system, we interviewed the system’s manufacturer.
We also watched aircraft departures, recorded single-event noise
meter readings and flight tracks, and compared our results to
data obtained from the port district’s noise-monitoring system.
Finally, to determine the frequency of deviations from original
flight plans at Lindbergh Field, we reviewed flight track data and
interviewed FAA staff. (cid:1)

CHAPTER 1
San Diego’s Local Governments Must
Do More to Further Reduce
Lindbergh Field’s Noise Impact Area
CHAPTER SUMMARY
T
he San Diego International Airport at Lindbergh Field
(Lindbergh Field) is a noise problem airport and the
San Diego Unified Port District (port district) has received
variances to the noise standards from the California Department
of Transportation (Caltrans). The variance process requires the
port district to move toward reducing incompatible land use
within the noise impact area to zero.
The port district’s current residential sound-attenuation
program, designed to upgrade existing structures, offers promise.
However, problems with building permits arising from public
concern about preserving the architectural and historical
integrity of properties within the noise impact area have delayed
the program’s implementation. The port district has made little
progress in implementing its military sound-attenuation
program because the U.S. Marine Corps is ineligible for Federal
Aviation Administration (FAA) funding and the port district had
to seek other alternatives. The county of San Diego (county),
which is responsible for compliance with state airport
regulations, has virtually disbanded the board that was charged
with ensuring compliance with the variance. Moreover, the city
of San Diego (city) failed to consider noise impact issues when
granting new building permits. Aircraft noise continues to affect
thousands of residents within the noise impact area.
COMMUNITY CONCERNS AND MILITARY
NEGOTIATIONS SLOW IMPLEMENTATION OF
SOUND-ATTENUATION PROGRAMS
Although the port district has funded improvements to schools
within the San Diego Unified School District, delays in the
startup of its residential and military sound-attenuation programs
have slowed its ability to further reduce Lindbergh Field’s noise
impact area. The port district estimates that more than 28,000
15
people are affected by the noise within the 1.3 square miles of
the noise impact area. When granting a variance, Caltrans
requires the port district to develop and implement programs to
reduce its noise impact area to an acceptable degree over a
reasonable period. However, it took nearly two years of
negotiations between the city, county, military, community
representatives, and the port district to agree in October 1997 to
include the military and residential sound-attenuation programs
in its seventh variance.
The port district has successfully implemented the San Diego
Unified School District sound-attenuation program. The port
district and the FAA provided about $14 million to the school
district. By August 1999, six schools in the noise impact area
received sound-attenuation upgrades to reduce the airport noise.
Progress in the residential sound-attenuation program has not
been as steady. The program’s goal is to achieve an interior noise
level of 45 decibels in eligible dwellings. Homes eligible for the

and limit the property owner’s ability to initiate legal action
related to aircraft noise. In return, the property owners can
receive upgrades to windows, doors, attics, and wall insulation
and have air conditioning installed at no cost.
The port district receives FAA grant money for the residential
sound-attenuation program. The FAA had awarded a total of
$10 million as of September 2000. The port district will
contribute about $2 million for the program. The port district
intended to begin upgrading eligible homes in 1999, but the
program was delayed when the city’s Historical Resources Board
(historical board) voiced concerns about the preservation of
some homes within the noise impact area. The historical board
instructed city administrators not to issue building permits to
the port district and asked the port district to develop an
inventory of area homes with historic value. The port district
completed the inventory in April 2000 and expects more than
200 residences to receive upgrades by January 2002.

THE COUNTY IS NOT PROPERLY MONITORING THE
PORT DISTRICT’S PROGRESS
State law requires the county to enforce the noise regulations
established by Caltrans. San Diego County established its Noise
Control Hearing Board (noise board) to enforce the terms and
conditions of Lindbergh Field’s variance to the noise standards
and submit quarterly reports to Caltrans based on information
provided by the port district. There are no specific requirements
outlining how often the noise board must meet to certify the
accuracy of the port district’s quarterly reports. However, the
noise board has not met since April 1999, so it cannot ensure
that the port district is meeting the requirements stipulated by
the variance.
During its review of Lindbergh Field’s variance application,
Caltrans will hold a public hearing, under the provision of the
State’s Administrative Procedure Act, if any person or
governmental agency residing in, owning
property within, or having jurisdiction over the
noise impact area requests one. Lindbergh Field’s

include information such as a report of operations by airline,
aircraft type, and stage classification for each quarter and cumu-
lative six-month period ending June 30 and December 31. This
data allows interested parties to track the number of aircraft
considered to be excessively noisy.
In 1999, the port district required all regularly scheduled
commercial operations at Lindbergh Field to meet FAA
requirements for stage 3 certification. As a result, the port
district no longer needed to include operations by stage
classification in its quarterly reports. However, the port district
also stopped reporting on operations by airline and aircraft type.
A community member commented on the information missing
from the quarterly reports as early as March 1999 and requested
that the port district continue to report on operations by airline
and aircraft type, but the port district has not included this data
in its reports as of July 2000. The port district states that, in the
future, it will comply with the variance and include data on
operations by airline and aircraft type in the quarterly noise
reports sent to Caltrans.

THE CITY OF SAN DIEGO HAS FAILED TO ENFORCE
CERTAIN PROVISIONS OF LINDBERGH FIELD’S
COMPREHENSIVE LAND USE PLAN
The federal government recognizes the importance of land use
planning in mitigating noise impacts and considers it to be
among the most potent and affordable of all the compatibility
strategies. It therefore encourages airport operators to act as an
integral participant in the planning process, which includes
tracking the development taking place around their airports.
The city approved a comprehensive land use plan for Lindbergh
Field that the San Diego Association of Governments (SANDAG)
18
adopted. However, the city has not complied with certain plan
requirements. Consequently, it has impeded the port district’s
progress in reducing its noise impact area.
The SANDAG, composed of council members, mayors, and a
county supervisor from each of the region’s 19 local governments,
is also the airport land use commission for the San Diego region.
The comprehensive land use plan that the SANDAG adopted in
February 1992, with a subsequent amendment in April 1994,

update its avigation easement requirements. The ordinance still
requires the approval of the Coastal Commission, which
oversees local coastal programs.
In January 1997, the port district identified a number of new
residential homes within the noise impact area for which it had
not received avigation easements. Despite working with the port
district to implement plan provisions for obtaining avigation
easements, the city remains inconsistent in its enforcement of
plan requirements. For example, as part of its discretionary
permit process, the city prepares and makes available to the
public an environmental report for new developments. The
city’s September 2000 environmental analysis for a new eight-
unit development incorrectly stated that this proposed
apartment complex would be a compatible land use, and the
city did not address the need for an avigation easement in the
future. As early as 1997, the city knew that certain provisions of
the land use plan, including the avigation easement
requirements, were internally inconsistent, and as a result, its
staff disagreed on exactly when to apply the provisions. If the
city believed that the plan contained certain inconsistencies, it
should have taken action sooner to seek clarification and
implement plan provisions.
19
The SANDAG also bears some responsibility for ensuring that
certain provisions of the land use plan are met. Specifically, the
plan requires the SANDAG to monitor the city’s general and
community plans, zoning ordinances, and building regulations.
Initially, the SANDAG believed that it adequately monitored the
city’s compliance with the plan, and that the city’s ordinance
covered Lindbergh Field. However, five years after adoption of
the plan, port district staff recognized the omission of Lindbergh
Field from the ordinance. Although the omission eventually was
corrected, the SANDAG’s failure to ensure that all the city’s
regulations were consistent with the plan before 1997 contrib-
uted to the city’s delays in seeking the necessary avigation
easements to reduce incompatible land developments.
RECOMMENDATIONS
The port district should continue its negotiations with the U.S.
Marine Corps to resolve noise-related issues at the Marine Corps
Recruit Depot. It also should continue to report on operations
by airline and aircraft type as the variance requires.
To maintain proper oversight of the port district’s progress in
meeting the conditions of Lindbergh Field’s variance and to
meet its regulatory responsibilities, the county should reactivate
the noise board. It should ensure that the noise board meets
quarterly and submits regular and complete reports to Caltrans.
To fully implement the comprehensive land use plan and
prevent any additional incompatible land uses, the city should
develop procedures to ensure that property owners obtain the
necessary avigation easements for new developments within the
noise impact area. The city also should make certain that its
general and community plans, zoning, and regulations and
ordinances are consistent with the comprehensive land use plan.
Finally, the SANDAG should comply with the plan requirements
for ensuring that the city’s general plan and ordinances agree
with the comprehensive land use plan. (cid:1)

CHAPTER 2
The Port District Cannot Impose
Noise Restrictions Without FAA
Approval, but It Can Improve Its
Community Relations in Other Ways
CHAPTER SUMMARY
N
oise problems at the San Diego International Airport at
Lindbergh Field (Lindbergh Field) have provoked
complaints from the surrounding communities for
many years. In response, the Airport Noise Management Office
of the San Diego Unified Port District (port district) makes
available a complaint hot line. The port district is limited in
addressing community complaints because it cannot impose
noise and access restrictions on older aircraft that have been
retrofitted to meet the Federal Aviation Administration’s (FAA)
requirements for stage 3 certification but still produce substan-
tial levels of noise.
Distrust of the port district’s flight-tracking and noise-monitoring
system data further hampers positive community relations.
Although our flight observations were consistent with the data
obtained from the port district’s noise-monitoring system, the
manner in which the district’s Airport Noise Advisory Committee
(committee) interacts with the community and the cessation
of the county of San Diego’s (county) Noise Control Hearing
Board (noise board) may be partly responsible for the
community’s distrust.
Although the FAA added “noise dots” to air traffic control radar
maps to define regular departure paths and to limit flights over
residences in the southern area of Point Loma, we found that the
noise dots are only minimally able to affect the area’s overall
noise level. Moreover, the anticipated growth in Lindbergh
Field’s aircraft operations warrants the necessity for the San Diego
Association of Governments (SANDAG), local agencies, and
others to band together and decide whether to expand or
relocate Lindbergh Field.
21
THE PORT DISTRICT CAN IMPROVE ITS
COMMUNITY RELATIONS
Lindbergh Field’s variance to the noise standards requires the
port district’s Airport Noise Management Office to respond to
aircraft noise complaints. It uses a noise-monitoring system to
measure noise, track flight paths, and calculate the noise impact
area. The Airport Noise Management Office uses this data to
respond to complaints. Although some community members
consider the noise-monitoring system data suspect, we found it
to be accurate. However, the cessation of the county’s noise board
and the port district’s failure to effectively communicate with
community members through its committee may be responsible

port district’s data.
The public can register complaints through a hot line established
by the port district’s Airport Noise Management Office. The hot
line receives an average of 500 complaints semiannually. After
researching each complaint, the Airport Noise Management Office
responds to complainants who have so requested. Our analysis of
Lindbergh Field’s data shows that a single household may file
numerous complaints. For example, one household filed 46 com-
plaints between January and June 1999, while another household
filed 20 between July and December 1999. Moreover, as Figure 3
shows, one household made 318 calls, or 53 percent of the total
complaints, between January and June 2000.
Complaints range from a loud aircraft overhead to possible
curfew violations. Another common complaint is that aircraft

Management Office also receives complaints regarding aircraft
not landing or departing from Lindbergh Field, such as banner
flights, emergency response flights, or military flights. In these
cases, the Airport Noise Management Office attempts to identify
the aircraft and inform the caller of the proper jurisdiction to
lodge its complaint.
Another forum for residents to voice their concerns is the com-
mittee, established by the port district in 1981 and composed of
14 voting members from various agencies, industries, and other
interested groups. The composition of the committee was a
requirement of the existing variance and was approved by the
FAA. The committee meets at least once each calendar quarter.
Any community members wishing to address the committee
must do so within a time limit of three minutes.

The FAA’s “Noise Dots” Restrict Flights Over Residential Areas
In December 1998, responding to concerned citizens and a
congressional representative about aircraft departures, the FAA
implemented new procedures and installed new radar maps with
a series of “noise dots” that define regular departure paths. These
improvements have helped to redirect air traffic away from
residential areas in Point Loma.
The new procedures direct aircraft 1.5 miles west of the
shoreline before turning south. Aircraft also are directed so they
do not cross Point Loma until as far south as Fort Rosecrans
National Cemetery. The FAA representatives have also made
assurances that Lindbergh Field air traffic controllers direct
departing aircraft to a 275- or 290-degree heading when cleared
for takeoff. Figure 4 shows an example of flights using the
275-degree departure heading between 7:10 p.m. and 8 p.m. on
September 20, 2000. The figure also depicts the radar gate
through which aircraft should fly to comply with the FAA “noise
dot” procedures.

25
Departing aircraft do not fly to a specific point on the 275-degree
departure heading. Instead, air traffic control directs aircraft to
fly through a departure gate about two miles wide and
1.5 nautical miles west of the shoreline. As a result, an aircraft
can fly from the departure end of runway 27 to the southern end
of the departure gate and cross the shoreline as far south as
Orchard Avenue. Our review of daily flight track data for the
months of April 1999, October 1999, and July 2000 showed a
decreasing number of flights outside the departure corridor
bounded by the “noise dots.” The Airport Noise Management
Office routinely reviews daily flight track data and makes a list
of any flights that occur outside the “noise dots.” It submits that
list to the FAA representative at the air traffic control facility.
When the FAA identifies a specific cause behind multiple irregu-
lar flight tracks, it follows up to correct the problem. In some
instances, the reported irregular flight tracks are warranted
because of safety considerations.
RETROFITTED STAGE 3 AIRCRAFT CONTINUE TO
CAUSE PROBLEMS
Since January 1, 1999, the port district has prohibited noisy
stage 2 planes, with the exception of general aviation aircraft
and operators that are not regularly scheduled. However, the
port district cannot unilaterally place noise or access restrictions
on old stage 2 aircraft that have been retrofitted with hushkits
to minimally meet the FAA’s noise-level criteria for stage 3
certification.
Significant noise differences exist among the aircraft that
comply with stage 3 noise levels. New stage 3 aircraft, such as
Boeing 757s, are much quieter than older Boeing 727s with
hushkits, which reduce aircraft engine fan and compression

In 1989, prior to the act, the port district did
impose curfews on the use of Lindbergh Field. No departures or
engine run-ups can occur between 11:30 p.m. and 6:30 a.m.
Departures of aircraft not certified as stage 3 are prohibited
between 10 p.m. and 7 a.m. However, these restrictions do not
apply to emergency and mercy flights, as well as engine run-ups
associated with these flights.
The port district fines airlines $1,000 for the first curfew violation,
$3,000 for the second, and $5,000 for the third violation during
any calendar quarter. The port district also cites airlines that do not
fly the agreed-upon operations mix, imposing similar fines as it
does for the curfew violations but on a per-flight basis. Although
the port district does not impose the highest monetary fines on
airlines that violate its airport use regulations, it is working with
the FAA to ensure that its proposal for doubling the amount of its
fines will be consistent with federal law and policy.
PROJECTED INCREASES IN AIRCRAFT OPERATIONS
COULD MAKE FUTURE NOISE LEVELS EVEN HIGHER
Currently, more than 25 passenger and cargo airlines operate an
average of 630 flights in and out of Lindbergh Field daily.
According to the port district, aircraft operations at the airport
totaled 217,130 arrivals and departures in 1970. This number
declined through the 1970s, reaching a low of almost 133,700
in 1982 before increasing each year thereafter to about 220,000
in 1996. Moreover, a dramatic shift occurred in the distribution
27
of Lindbergh Field’s operations. In 1970, general aviation aircraft
accounted for almost 60 percent of aircraft operations, but by
1996 it was only 10 percent, with commercial carriers account-
ing for the remaining 90 percent. Total aircraft operations at
Lindbergh Field are projected to grow at an average annual rate
of 2 percent through 2020. At this rate, Lindbergh Field will
reach its maximum aircraft operating capacity of 275,000 by 2011.

given the anticipated growth, a decision must be made on
whether to expand or relocate Lindbergh Field.
RECOMMENDATIONS
To further its efforts to reduce the impact of aircraft noise and to
respond effectively to community complaints, the port district
should encourage more community involvement, such as using
working groups that include local citizen representation. In
addition, the port district should proactively participate in
finding ways to reduce or minimize the use of stage 3 certified
hushkit aircraft at Lindbergh Field.
To provide independent verification of the port district’s noise
information, the county of San Diego should reactivate the
Noise Control Hearing Board.
To more effectively address the anticipated growth in Lindbergh
Field’s aircraft operations, the SANDAG, local agencies, and
citizen’s groups should decide whether to relocate the airport.

We conducted this review under the authority vested in the California State Auditor by

Re: San Diego Unified Port District, San Diego International Airport - State Audit
Dear Ms. Howle:
This letter contains the comments of the San Diego Unified Port District (“the District”) in its capac-
ity as the certified proprietor of San Diego International Airport (“SDIA” or “the Airport”) with respect
to the draft audit report that the Bureau of State Audits (“BSA”) released for internal District review
and comment on October 20, 2000. The District appreciates the BSA’s efforts in connection with
the recent audit of the District and is in general agreement with the draft report.
General Comments
The District wishes to provide the following comments regarding the draft audit report:
1. The second paragraph on page 16 and the third paragraph of page 18 references a “Military
Sound Attenuation Program”. Although the seventh variance process included discussion
regarding the possible implementation of a military sound attenuation program, the program
was never adopted as part of the seventh variance because, as the draft report accurately
indicates, the United States Marine Corps is ineligible for FAA funding. Although negotiations
are continuing with the Marine Corps for a land exchange that allows the Airport to extend its
North Taxiway, any noise mitigation provided as a result of this transaction has no relation to
1
the formerly proposed “Military Sound Attenuation Program” and therefore should be refer-
enced in the report as “Future Noise Mitigation at the Marine Corps Recruit Depot”.
2. The second paragraph on page 28 discusses the Airport Noise Advisory Committee (ANAC)
meeting that was held on September 14, 2000. It is important to emphasize that the ANAC
meeting attended by the state auditors was not reflective of the general nature of these
meetings in the past. Rather, it appears that the attendance by the auditors as well as a

representative from Caltrans, coupled with the pending variance application and the presence
of local press and television cameras necessarily stimulated some of the unusual level of
“outbursts”. Although the District is certainly willing to consider any recommendations the
State believes is appropriate regarding the District’s community outreach efforts, the District
2
continues to believe that having a public input opportunity during ANAC meetings is important.
The report should also recognize that during the seventh variance process, Caltrans ap-
proved the composition and role of ANAC as negotiated with the community. In addition, the
FAA through the Part 150 amendment process sanctioned the structure of this Committee.
3. The second paragraph on page 30 discusses the District’s phase-out of Stage 2 aircraft. The
3
report should be revised to accurately indicate that the District’s Stage 2 phase-out was
accomplished one year ahead of the federal mandate under the Airport Noise and Capacity
Act of 1990.
4. The second complete paragraph on page 33 references the issue of expanding or relocating
Lindbergh Field. The report should recognize that the District’s long term solution on this
matter is to work with regional agencies, local governments and interested stakeholders to
develop a specific program for a Regional Strategy for Air Transportation. This program is
designed to determine how best the region can use existing air and ground transportation
facilities to meet the region’s air transportation needs.
Port District Recommendations from Draft Report
With respect to the four specific recommendations of the audit directed to the Port District, our
response to each recommendation is as follows:
1. Continue negotiations with the United States Marine Corps to resolve noise-related
issues at the United States Marine Corps Recruit Depot (MCRD).
As previously referenced, negotiations are continuing with the United States Marine Corps for
a land exchange that allows the Airport to extend its North Taxiway. As part of these negotia-
tions, the District is addressing noise impacts to the MCRD. The District expects that a public
statement regarding the results of these negotiations and the agreements reached between
the District and the Marine Corps in the near future.
32

2. Continue to report on operations by airline and aircraft type, as the [current Caltrans]
variance requires.
The District has already advised Caltrans that it will include this information in future quarterly
reports to the County of San Diego and Caltrans, and that the information will continue to be
made available to the public. The District has separately provided Caltrans and the public
with this information for the period from January 1, 1999 through March 31, 2000.
3. The Port District should improve its public relations efforts by encouraging more
community involvement, such as using working groups that include local citizen repre-
sentation.
As previously mentioned, the specific structure of the ANAC was negotiated with community
2
representatives as part of the seventh variance. In addition, the ANAC structure has been
included in the District’s FAA approved Part 150 program.
The District continues to believe that the ANAC, with its broad base of membership by local
community representatives is still the best forum to at least begin public discussions of issues
related to noise from SDIA operations. However, the Board of Port Commissioners, the
ANAC’s policy body, will be advised of this recommendation. District staff will also suggest
that in the future the ANAC may wish to address some issues by forming issue specific
working groups, and that District staff would, where appropriate, support a smaller “working
group” approach if both the Board of Port Commissioners and the ANAC believe this is
consistent with encouraging opportunities for public dialogue.
Further evidence of the District’s public relations efforts and our desire to increase community
involvement in Airport matters can be demonstrated through the Airport Master Plan process.
At the outset of the process, a Public Working Committee and Technical (i.e., FAA, airlines,
etc.) Working Committee were created, which in the consideration of future alternatives for
the Airport, considered noise impacts, among other factors. In order to engage the general
public in this effort, approximately two hundred thirty (230) community meetings both inside
and outside the noise impacted areas have occurred. At these meetings, information on
current and future noise impacts was always available and frequently discussed in a public
setting. In addition, these meetings provided a forum for individuals to discuss noise impacts
one on one with District staff and technical consultants. As the District moves into the State
and Federal environmental review stage of the Airport Master Plan process, current and
future noise impacts from SDIA will continue to be discussed in public settings.

4. The Port District should proactively participate in finding ways to reduce or minimize
the use of Stage 3 certified hushkitted aircraft at Lindbergh Field.
The District intends to pursue this issue by dealing directly with commercial air carriers using
“hushkitted” Stage 3 aircraft in their SDIA operations. The District will explore with them the
possibility of voluntary actions reducing the use of “hushkitted” aircraft at SDIA, and District
staff will continue to advise the ANAC of the results of those efforts.
Although the District is committed to proactively participating in finding ways to reduce or
minimize the use of Stage 3 certified hushkitted aircraft at the Airport, it is important to recog-
nize that the District has already demonstrated through its enforcement of the Airport Use
Regulations, which embody the time of day restrictions (curfew) and the phaseout of Stage 2
aircraft in 1999, that the District is committed to continuing to address noise concerns in an
aggressive and comprehensive manner. These Airport Use Regulations, which were adopted
by the District with knowledge of the critical importance of adequately addressing noise
issues in a manner which is comprehensive in nature, are notably some of the most stringent
regulations in the entire country. Aggressive enforcement of these regulations will continue to
play an important role in the District’s continuing operation of the Airport.
Conclusion
The District appreciates the opportunity to comment on the draft audit report. If you have any
questions regarding our comments or need additional information regarding any of the issues
discussed, please do not hesitate to contact us.
Sincerely,
(Signed by: Thella F. Bowens)

o provide clarity and perspective, we are commenting
on the San Diego Unified Port District’s (port district)
response to our audit report. The numbers correspond
with the numbers we have placed in the port district’s response.
1
Page 17 of our report states that the potential exchange of
property between the port district and the U.S. Marine Corps
was unrelated to the variance process. However, to provide
further clarity to the report, we modified our text on page 17.
2
As stated in our report, we too believe that the public should
have an opportunity during Airport Noise Advisory Committee
(committee) meetings to voice their concerns. We have simply
recommended that the port district also explore additional
techniques for developing solutions to airport noise, including
smaller working groups that include community members.
Further, page 23 of our report does recognize the composition
of the committee as a requirement of the existing variance and
the Federal Aviation Administration’s approval. This change
was previously discussed and agreed upon with port district
staff during our exit conference on October 24, 2000.
3
The port district implies that our report is inaccurate and that it
should be revised. We disagree. Our report clearly and accurately
states on page 26 that the port district prohibited noisy stage 2
aircraft as of January 1, 1999. This is consistent with the port
district’s Amended Airport Use Regulations (March 7, 1989) and
its August 16, 2000, request for variance to the California
Department of Transportation. While the port district correctly
indicates that its stage 2 phase-out was accomplished one year
ahead of the federal mandate, it is not relevant to our discussion.

Dear Ms. Howle:
We have reviewed our portion of your draft version of Report No. 2000-126 about San Diego
International Airport at Lindbergh Field and have only a few comments.
In general, we would like to indicate that the audit team has done a good job with their objective
approach in collecting information.
We agree with the overall perspective of this audit. There is a need for the County of San Diego to
insure that the Noise Control Hearing Board meets on a regular basis to review quarterly reports
and to make recommendations to the Department of Transportation (Caltrans), Aeronautics Pro-
gram about the Port District's performance in fulfilling the conditions of Lindbergh Field's existing
variance.
County staff has reviewed the Administrative Code (SEC. 607) that created the Noise Control
Hearing Board and wishes to note that the most current version was last amended on 7/2/87. The
Noise Control Hearing Board is composed of eight members that are appointed by the Board of
Supervisors. They serve on a voluntary basis and the County has provided staff support and
meeting rooms to conduct their business. The loss of County staffing created a vacancy in April,
1999 that has contributed to the Board inactivity that has occurred. County staff has made an effort
to contact all Board members to determine their availability for a meeting in November to perform
their duties.
Again, we thank your staff for their diligence and look forward to supporting these recommenda-
tions to insure that the Noise Control Hearing Board will perform its duties in the future.
Sincerely,
(Signed by: Pam Elias)

Dear Ms. Howle:
Subject: Audit 2000-126 - San Diego International Airport at Lindbergh Field: Local Government,
Including the San Diego Unified Port District, Can Improve Their Efforts to Reduce the
Noise Impact Area and Address Public Dissatisfaction
The City of San Diego has read the portion of the Bureau of State Audit’s report pertaining to the
City of San Diego’s responsibilities and recommendations related to Lindbergh Field Comprehen-
sive Land Use Plan implementation. We agree with the recommendations regarding the City’s role
in preventing future incompatible land uses and assuring consistency among our policy documents
and implementing ordinances, including the Comprehensive Land Use Plan and the recently
adopted Airport Environs Overlay Zone.
The application of the Airport Environs Overlay Zone [AEOZ] to Lindbergh Field [Attachment 1] is
the culmination of a three-year process that involved City staff, Port District staff, and
San Diego Association of Governments [SANDAG] staff. There were many meetings among the
staffs, including one with State CALTRANS officials, to look at the appropriate provisions that would
protect Lindbergh Field. The meetings took a significant amount of time to conclude due to the
legitimately divergent policy goals and responsibilities of the City and of the Port District. Two key
differences were the level at which avigation easements for noise should be required, and the type
of development that triggers the need for the easement.
The AEOZ, recently adopted by the City Council and subject to pending Coastal Commission
approval, addresses these two issues that are key to protection of Lindbergh Field. The noise
level at which avigation easements may be triggered is the 65 dB CNEL level. The San Diego City
Attorney’s office, in an April 16, 1998, memo [Attachment 2] determined that this noise level was
the appropriate level at which the City had a responsibility to acquire an easement, under certain
circumstances, while recognizing inconsistencies within the adopted CLUP. The AEOZ also
requires avigation easements as a condition for any development which increases the number of
dwelling units within the AEOZ. This provision is more encompassing than the CLUP because the
CLUP addresses easements only for discretionary projects.
*California State Auditor’s comments appear on page 43.

While the AEOZ was not put into place concurrently with the adoption of the CLUP, the City has
had procedures to deal with the issues on an interim basis. An August 12, 1992, memorandum
[Attachment 3] directs staff to review projects within the Airport Influence Area [AIA] for Lindbergh
Field. Informal interviews with City staff reveal that applicants for all types of building permits
within the Lindbergh Field AIA were sent to the Port District after the CLUP’s adoption to offer
easements to the Port District. In addition, the current discretionary review process includes CEQA
review for noise impacts from Lindbergh Field, and an opportunity to include conditions in discre-
tionary permits requiring avigation easements prior to obtaining building permits. The Uniform
Building Code, for new residential structures, requires noise studies and attenuation to reduce
interior noise levels to 45 dB CNEL, regardless whether the structure is processed through a
ministerial or discretionary permit.
12
The example given [a project in September 2000] where the Port District did not receive an ease-
ment is actually an example of how the discretionary process is meant to identify easement situa-
tions. As with all discretionary projects like this one, conditions will be included in the permit for this
project to require an avigation easement to be given to the Port District. The reason the Port has
not received the easement is that the project has not been set for a public hearing yet, and thus
the permit conditions have not been drafted. The Port District appropriately responded to the draft
environmental document early in the discretionary process, as an additional check that a noise
impact needed to be addressed.
The application by the City of the Airport Environs Overlay Zone to the Lindbergh Field Airport
Influence Area will help increase the certainty that avigation easements will be acquired in the
circumstances dictated by the ordinance provisions. The City of San Diego looks forward to
establishing a formal, permanent process that facilitates the acquisition of these avigation ease-
2
ments. It should be noted that neither the City of San Diego nor SANDAG has prevented the Port
District from acquiring avigation easements through its own initiative since the adoption of the
Comprehensive Land Use Plan. City staff, during discussions with CALTRANS staff, became
aware that, in certain jurisdictions, the airport operator purchases easements from property own-
ers.
We note, finally, that the title of your audit includes “address[ing] public dissatisfaction” related to
noise impacts. Acquisition of avigation easements by the Port District does not actually reduce the
boundaries of a noise impact area from the airport, nor does it reduce the actual noise. Ease-
3
ments legally reduce the number of incompatible structures. In the City of San Diego’s experience
dealing with public dissatisfaction related to airport noise, dissatisfaction has not been reduced by
promoting the acquisition of avigation easements unless the granting of that easement is war-
ranted by the type of development proposed.

COMMENTS
California State Auditor’s Comments
on the Response From the
City of San Diego
T
o provide clarity and perspective, we are commenting on
the city of San Diego’s (city) response to our audit report.
The numbers correspond with the numbers we have
placed in the city’s response.
1
While the city correctly states that the project has not been set
for a public hearing yet, where an avigation easement could be
obtained, the city should have identified the need for an
avigation easement earlier. As shown on page 19, as recently as
September 2000 the city missed an opportunity to include
conditions in a discretionary permit to require an avigation
easement for a new eight-unit apartment complex located in the
noise impact area. Specifically, in preparing the environmental
report required as a condition of the California Environmental
Quality Act (CEQA), city staff incorrectly stated that the proposed
development was a compatible land use and did not recognize
the need for an avigation easement. Identifying the need for an
avigation easement during the initial stages of the permit process,
such as the CEQA review, would further ensure that the city
obtains avigation easements when required.
2
The city is attempting to minimize its responsibility for ensuring
that it obtains avigation easements. The comprehensive land use
plan specifically outlines this as a function of the city. Therefore,
it is not the responsibility of the port district to seek avigation
easements for new developments during the permit process.
3
The city is responding to a portion of our report and does not
have the benefit of the full context of our discussion on avigation
easements. Our report does not state that the promotion of
avigation easements reduces public dissatisfaction relating to
airport noise. Rather, on pages 2, 16, and 19, our discussion
focuses on the legal ability of avigation easements to convert
land uses from incompatible to compatible.

Dear Ms. Howle:
The staff of the San Diego Association of Governments (SANDAG) have reviewed the redacted copy of
the report entitled, San Diego International Airport at Lindbergh Field: Local Government, Including the
San Diego Unified Port District, Can Improve Their Efforts to Reduce the Noise Impact Area and Address
Public Dissatisfaction. The comments contained in this letter are staff comments and they have not been
reviewed or approved by the SANDAG Board of Directors.
The redacted portion of the report that we have reviewed contains two recommendations that are di-
rected towards SANDAG. This letter provides comments directed to each recommendation.
Recommendation #1
Finally, SANDAG should comply with the plan requirements for ensuring that the City’s general plan and
ordinances agree with the comprehensive land use plan.
Comments
1. SANDAG takes its responsibility as the region’s Airport Land Use Commission seriously and makes
every effort to insure that the airports that have comprehensive land use plans are protected from
incompatible development. Because SANDAG does not have local land use authority, it is neces-
1
sary for SANDAG to rely on the city(ies) to protect the airports. SANDAG was satisfied that the
Council through the approval of Resolution 278103, its participation on the Board of Directors, and
the active participation of the local Councilman as chair of the advisory committee that produced the
plan, would protect the airport. Since then, the City of San Diego, as the local land use agency, has
developed policies and procedures to protect Lindbergh Field from new incompatible development.
Exhibit #1 is a copy of the City’s Resolution.
2. The supporting text for this recommendation, in our judgement, is incorrect. The City of San Diego
presented the Airport Environs Overlay Ordinance to the SANDAG Board on April 27, 1990.
2
Lindbergh Field is not mentioned in the report because the Lindbergh Field CLUP was not adopted
until February 1992. The purpose of the ordinance is to implement all adopted CLUPs. The City’s
adoption of the ordinance is a clear policy statement of the Council to protect the airports within its
jurisdiction from incompatible development by applying the ordinance. See exhibit #2.
3. The logic of your comment that SANDAG’s “failure to ensure the city’s regulations were consistent
with the plan prior to 1997 contributed to the city’s delays in seeking the necessary
*California State Auditor’s comments begin on page 47.
45
avigation easements to reduce incompatible land development” is incorrect. The City or the Port,
1
independent of SANDAG, has the authority to implement noise mitigation or abatement measures.
CLUPs are prepared as a result of a cooperative intergovernmental process and the implementa-
tion of the plan requires the similar cooperation.
4. Lindbergh Field is located in an urban setting. The local neighborhoods adjacent to the airport are
well established. The residential development that was constructed during the period of time the
airport wasn’t specifically cited in the ordinance was noise attenuated as required by the City’s
building code. Exhibit #3 is a letter from City staff to Port staff describing the city’s requirements.
3
While some easements may not have been granted, the airport was always protected from the
construction of new incompatible noise sensitive land uses.
Recommendation 2
To more effectively address the anticipated growth in Lindbergh Field’s aircraft operations, SANDAG,
local agencies, and citizens groups should make a decision on whether to expand or relocate the airport.
Comment
1. Policy steps have been taken to address the short- and long-term issues associated with commer-
cial aviation service. SANDAG’s Regional Transportation Plan (RTP) has several short- and long-
term aviation policies. The policies reflect the existing situation in that Lindbergh Field will continue
as the region’s commercial airport. In that regard, the SANDAG Board at its September 1999
meeting supported the Port’s two track master plan. Exhibit 3 is a copy of SANDAG’s September
1999 minutes that describe the Board’s action.
2. The RTP also identifies MCAS Miramar as a commercial airport site if it is no longer needed as a
4
military facility and it is closed as a result of Congressional action. Exhibit #4 is a copy of those
policies.
3. It is our opinion that this recommendation is unnecessary because there are public policies in place
5
that address the recommendation.
Finally, the process by which this audit was conducted could be greatly improved. A site visit at the
outset of the audit with a request for documents and an overview of the schedule and scope of the audit
6
would, in our judgement, provide a more comprehensive report.
We stand ready to help you in this process in any useful way.

COMMENTS
California State Auditor’s Comments
on the Response From the San Diego
Association of Governments
T
o provide clarity and perspective, we are commenting on
the San Diego Association of Governments’ (SANDAG)
response to our audit report. The numbers correspond
with the numbers we have placed in the SANDAG’s response.
1
While the SANDAG states that the city of San Diego (city) has
developed policies and procedures to protect Lindbergh Field, as
we state on pages 19 and 20 of our report, the amendment to
include Lindbergh Field into the Airport Environs Overlay Zone
did not occur until October 2, 2000. Also, the comprehensive
land use plan requires the SANDAG to monitor the city’s general
and community plans, zoning ordinances, and building regula-
tions. If the SANDAG had adequately monitored the city’s
compliance with the land use plan before 1997, it would have
recognized the omission of Lindbergh Field from the city’s
ordinance. It was the San Diego Unified Port District’s (port
district) discovery of new incompatible developments in 1997
that led the city to amend the ordinance.
2
The SANDAG is missing our point concerning the necessity of
amending the 1990 ordinance once the comprehensive land use
plan for Lindbergh Field was adopted in February 1992. As we
state on page 19, the city did not amend its ordinance to include
Lindbergh Field until October 2, 2000.
3
The SANDAG incorrectly states that the airport was always
protected from the construction of new incompatible land uses
even though some easements may not have been granted. As
shown on page 19, the port district identified a number of new
homes within the noise impact area for which it had not received
avigation easements. Further, according to California noise
standards, noise attenuation by itself is not sufficient to classify
a new development as a compatible land use without an
avigation easement.
47
4
We refer to this policy regarding MCAS Miramar on page 28 of
our report.
5
While the SANDAG states that public policies are in place, there
has been no final decision regarding Lindbergh Field’s expansion
or relocation. Moreover, as we state on page 28, the SANDAG, in
its role as the regional transportation planning agency is prima-
rily responsible for siting San Diego’s commercial airport. In its
2020 regional transportation plan, the SANDAG identifies MCAS
Miramar as a commercial airport site, but does not include
specific timelines for progressing toward this selection.
6
The SANDAG was not the focus of our audit. However, the
SANDAG has certain responsibilities that affect the port district’s
activities. The port district was able to provide us with sufficient
documentation concerning the SANDAG’s activities. Therefore,
we did not feel that a site visit to SANDAG was necessary.
On September 19, 2000, we conducted an initial interview
with SANDAG staff. Once we became aware of the need
to discuss SANDAG in our report, we sent a letter to the chair-
person of the SANDAG Board of Directors on October 2, 2000,
describing the audit scope as it related to SANDAG. We also
had several conversations between October 12, 2000, and
October 26, 2000, with the SANDAG to afford it an opportunity
to present its viewpoint on issues concerning the SANDAG.
