NOISE ELEMENT
CHAPTER I. INTRODUCTION
A. PURPOSE AND REQUIREMENTS
As required by Section 65302 of the Government Code, a Noise
Element shall be incorporated, as a mandatory element, into a
city or county General Plan. General purposes of such an element
are to provide sufficient information concerning the Community.
Noise Environment and to develop strategies to reduce adverse
impacts of noise related factors. Specific requirements are to
identify noise related problems and issues; to identify
particular noise sources; to provide a standardized mechanism for
the measurement of noise generated within, or what would have an
impact upon the study area; to establish and implement specific
policies that address noise conditions that may adversely affect
the inhabitants of this jurisdiction; and finally, to coordinate
all of this information into a document that shall be a guideline
for use in the development of the land use element of the General
Plan. In this manner, noise compatible land uses can be
established as well as creating a base upon which subsequent
noise control. ordinances are to be adopted. Noise control
measures are to be applied to existing conditions as well as in
conjunction with future planning and development processing.
0C
The sources of environmental noise to be considered in this
element as required by Section 65302f of the Government Code
shall include the following:
* Highways and freeways;
* Primary arterials and major local streets;
* Passenger and freight on-line railroad operations and rapid
transit systems;
Commercial., general aviation, heliport, helistop, and
military airport operations, aircraft overflights, jet
engine test strands and all other ground facilities and
maintenance;
* Local industrial plants, including but not limited to,
railroad classification yards;
* Other ground stationary noise sources identified by local
agencies as contributing to the community noise environment.
Section 65302f further states that certain formula shall be used
to present noise exposure information identifying noise levels
generated from the above listed sources. For the purposes of
this element, noise contours identifying exposure levels shall be
shown in terms of Community Noise Equivalency Level (CNEL).
These contours will be used as a guide for establishing a pattern
of land uses in the land use element that minimizes the exposure
- -of commun-ity residents to excessive noise.
-2-
Finally, this element shall include implementation measures and
possible solutions that address existing and foreseeable noise
problems. This element shall also serve as a guideline for
compliance with the state's noise insulation standards.
B. RELATIONSHIP TO OTHER ELEMENTS
As required by the State Government Code, in the preparation of a
single element to a city's General Plan consideration must be
given to the relationship of that element to the remaining
components of the plan. Since no element of the General Plan may
supersede or replace any other mandatory element, an internal
consistency among elements must also be demonstrated. The other
elements most relevant to the Noise Element are the Land Use and
Housing Elements.
By addressing type, location and density of land uses within the
city, the Land Use Element recognizes the need for orderly and
compatible development patterns. In this broad policy document,
issues relating to noise sources and noise exposure are
incorporated in general terms. Additionally the Land Use Element
addresses noise compatible land uses.
More specifically related to the Noise Element, the fo11_owing
goals established in the Housing Element demonstrate consistency
between those two elements.
-3-
1. The provision of decent, safe and suitable housing
accommodations for all persons who reside in the city.
2. The provision of quality living environment with protection
and preservation of the health, safety and welfare of the
residents of the city.
3. The encouragement of development reducing dependency upon
the automobile (thereby reducing associated noise) for
transportation by locating housing facilities convenient to
service and employment centers thereby enabling walking or
bicycling.
As to the relationship between the remaining elements of the
General Plan, where policies provide: buffer zones between
transportation systems; where permanent open space is mandated;
and/or references are made to the enhancement of the general
welfare of the community resulting from the improvement of
environmental conditions. This Noise Element is considered to be
consistent with those elements.
C. DEFINITIONS
For the purposes of this Noise Element, the following definition of
terms shall be used.
Decibel, db: A unit for describing the amplitude of sound, equal
to 20 times the logarith of the base 10 of the ratio of the
pressure of the sound measured to the reference pressure, which
is 20 micropascals (20 micronewtons per square meter).
-4-
A -Weighted Sound Level: The sound pressure level in decibels as
measured on a sound level meter using the A -weighting filter
network. An A -weighting filter de-emphasizes the very low and
very high frequency, components of the sound in a manner similar
to the response of the human ear and gives good correlation with
subjective reactions to noise.
CNEL: Community Noise Equivalent Level. The average equivalent
A -weighted sound level during a 24-hour day, obtained after
addition of five decibels to sound levels in the evening from 7
p.m. to 10 p.m. and after addition of 10 decibels to sound levels
in the night before 7 a.m. and after 10 p.m.
Equivalent Energy Level,
LEQ: The sound
level
corresponding
to a
steady state sound level
containing the
same
total energy
as a
time varying signal over a given sample period. Leg is typically
computed over 1, 8 and 24 hour sample periods.
Noise Exposure Contours: Lines drawn about a noise source
indicating constant energy levels of noise exposure. CNEL and
Ldn are the metrics utilized herein to describe community
exposure to noise.
-5-
Ambient: The composite of noise from all sources near and far.
In this context, the ambient noise level constitutes the normal
or existing level of environmental noise at a given location.
Intrusive Noise: That noise which intrudes over and above the
existing ambient noise at a given location. The relative
intrusiveness of a sound depends upon its multitude,duration,
frequency and time of occurrence, and tonal or informational
content as well as the prevailing ambient noise level.
Equal Noisiness Zones: Defined areas or regions of a community
wherein the ambient noise levels are generally similar (within a
range of 5 db). Typically, all sites within any given noise
sources.
-6-
CHAPTER II. GOALS AND POLICIES
A. GOALS
Ultimately, it is the goal. of the Noise Element to establish a
standard by which an environment for the people that live and
work within the City of Tustin may be created minimizing the.
detrimental effects associated with noise. The importance of
this goal is magnified when it is taken into consideration that
according to the Environmental Protection Agency, approximately
80 million people are significantly impacted by noise, 40 million
of which are exposed to levels that can damage their hearing or
otherwise affect their health.
Noise is not only detrimental to well-being, but also costly.
The World Health Organization has estimated that over $4 billion
is spent by United States industry each year for noise -related
absenteeism, reduced efficiency, workman's compensation claims,
and mental illness.
In addition to hearing loss, noise also can have a considerable
effect on human activities such as communication, sleep and task
performance, thereby contributing to annoyance and indirectly
affecting the general state of an individual's health and
well-being. (Source: County of Orange, Noise Element)
-7-
Realizing such problems, it is the specific objective of this
element to establish the basis from which future development
within the City of Tustin shall be approached, at least in part,
in terms of reducing negative impacts resulting from noise.
Additionally, by' identifying major noise producing sources, and
determining an acceptable noise level conducive to the orderly
and compatible development of the City; and giving proper
consideration to existing land uses, this element seeks to reduce
in the most appropriate manner overall noise levels as they
currently exist.

CHAPTER III. IDENTIFICATION OF DISE SOURCES
As required by Section 65302f of the Government Code, the following
noise sources havng an impact on the Community Noise Environment have
been identified.
A. EXISTING SOURCES
The north/south Costa Mesa Freeway (Interstate 55) from Fairhaven
Avenue to Warner Avenue. (A significant portion of this freeway
is recessed, which contributes favorably toward noise control.)
The diagonal northwest/southeast Santa Ana Freeway (Interstate
5), from Williams Street to Myford Road.
Primarily seven major arterial streets; Seventeenth Street,
Irvine Boulevard, First Street, McFadden Avenue, Newport Avenue,
Red Hill Avenue, Edinger Avenue and Walnut Avenue. Exhibit 1
shows the noise contours for these selected street systems.
The Santa Fe Railway line in the southern sector, running
northwest/southeast commencing at the intersection of the Newport
Freeway and Edinger Avenue, paralleling Moulton Parkway to Myford
Road.
-9-
�1 1
The Marine Corps Air Station (Helicopter) on the southern -most
edge of Tustin. In addition to the facility itself, the
"Browning Corridor" must be considered as a noise source. The
corridor is used as restricted airspace for helicopter
operations. This airspace covers an area 3/4 of a statue mile
wide with its easterly boundary coincidental with Myford Road and
extending straight out from the base in a northwesterly direction
over the study area approximately end at lower Peters Canyon
Reservoir. A 24 hour noise study of this corridor is included in
Appendix VII B of this Element. Information also contained in
this appendix, as it pertains to the Browning Corridor, were
_.comp-ited for the -Master Plan for MCAS(H) Tustin.
The major air approach pattern to the John Wayne Airport, which
traverses the city from Irvine Boulevard at Prospect Avenue to
Warner Avenue at the Newport Freeway impacts.the City.
The light industrial area contained within the southwestern -most
sectors of the City.
B. P0TE11TIAL SOURCES
In addition to listing existing noise sources, potential sources are
also identified.
-10-
o
New sources in conjunction with and resulting from, the
development of Mixed Land Uses in the presently undeveloped area
bounded by Irvine Boulevard and Interstate 5 between Myford Road
and Browning Avenue. These uses may include, but are not limited
to, residential. units of varying density, a 50 acre auto center,
and traditional commercial/retail uses.
Noise that will be generated by new automotive transportation
systems in the East Tustin (Peter's Canyon) area including but
not limited to: The Eastern Corridor, the Foothill Corridor, the
Portola Parkway, the extension of Jamboree and Myford Roads, and
the reconstruction of the Myford Road/Interstate 5 interchange.
Projected CNEL contours for major circulation systems within the
East Tustin area are listed in Table I and Exhibit 2.
The Sante Fe Railway line listed as an existing noise source was
at one time considered as a path for a proposed high speed rail
system (Bullet Train).
As a result of a settlement agreement between the County of
Orange and several organized community groups, limitations on the
number of commercial aircraft arrivals and departures at John
Wayne Airport have been established.
Until March 31, 1990, a maximum of 55 regulated Average Daily
Departures (ADD) have been authorized. "Regulated" aircraft are
classified either Class "A" or Class "AA." Class "A" aircraft
-11-
are defined as aircraft with a gross take -off weight not in
excess of 128,000 pounds, configured with more than 75 passenger
seats, and with quarterly Single Event Noise Exposure Levels
(SENEL) not in excess of 100 dB(A) at noise monitors M-6 and M-7
and 98.5 dB(A) at monitor M-1. (See Exhibit 3 for location of
monitors).
Class "AA" aircraft are defined as aircraft with a gross take -off
weight not in excess of 128,000 pounds, configured with more than
75 passenger seats, and quarterly SENELs not greater than 89.5
dB(A) at any departure monitoring station.
Of the 55 ADD's authorized, no more than 39 shall be Class "A"
aircraft.
An additional constraint on the number of commercial flights
revolves around a maximum number of annual passengers. Until
March 31, 1990, regardless of aircraft classification, the
maximum number of passengers for regular commercial services is
limited to 4.75 million.
Commencing on April 1, 1990, the number of ADDS will be permitted
to be increased to 73 (no more than 39 being Class "A" aircraft)
and the maximum annual passenger service level will be limited to
8.4 million.

CHAPTER VI. IMPLEMENTATION PROGRAM
These implementation policies suggest general priority policies for
the city of Tustin to -follow in implementing this Element of the
General Plan.
The city shall:
Review development to avoid existing noise impact areas until
operational changes or other noise abatement measures are
implemented.
Act to reduce noise levels and encourage development of
noise -reducing materials and equipment in its purchasing policy.
Noise should be made_a consideration in city purchasing decisions
for equipment producing noise levels greater than 65 dB(A) at 50
feet under normal operating conditions. Recommended policy is
that purchase of less noisy item should be required if reduction
is 5 dB from noisier item and cost is no more than 1.1 times
greater, or noise reduction is 10 dB over competitive item and
cost is no more than 1.25 times greater.
Discourage regional, state or federal actions which increase the
noise levels in the city, and take a strong stand on actions
which increase the noise levels beyond acceptable limits.
-15-
Aid in, and strongly encourage, the enforcement of federal and
state standards for noise -producing equipment including cars,
motorcycles, trucks, etc.
Work with the Orange County Airport Land Use Commission in
developing a plan for compatible use in airport noise and crash
hazard areas.
Discourage actions by private developers which increase noise
impact or do not account for noise impact already existing when
feasible alternative actions exist.
Encourage the use of circulation systems which do not produce
high noise levels, including bicycle and pedestrian systems.
Not allow credit for open space areas in developments in
zones with a CNEL 65+ except when shielded from noise sources by
appropriate noise barriers.
Maintain and revise as necessary a comprehensive noise ordinance
relating to noise sources and requiring sound insulation in
building construction in all noise impact areas proposed for
residential or other noise -sensitive development.
-16-
CHAPTER VI. ENVIRONMENTAL ASSESSMENT
The Noise Element as drafted will have no adverse impact on the
environment and in fact is designed to enhance the quality of living
within the city of Tustin. Documentation supporting the finding of no
adverse impact is found in the initial study questionnaire completed
for the Negative Declaration of Environmental Impact prepared in
conjunction with this project.

Subject: Helicoptor Noise Study In the East Tustin Browning Air
Corridor.
Dear Mr. Davis:
At your request a noise study was performed on January 10, 1986 near
the intersection of Myford Road and Irvine Blvd. in the City of Tustin,
to determine what noise exposure could be expected from helicopters
flying the "Browning Corridor" to the Santa Ana Marine Air Station
(LTA).
Two methods were used to measure the intruding noise. (1) a Digital
Acoustics Type 603 recording sound level was installed in a City of
Tustin pickup truck. The recording was then continued for twenty four
hours in an attempt to determine the single event (SENEL or SEL) for
each fly by. (2) a Digital Acoustic Type 607 community noise monitor
in conjunction with a Hewlett Packard Type 7155 chart recorder to obtain
a graphical recording as an addition to the digital print out while
visual observations were being made. The Marine Corp assisted in
identifying the different helicopter not only by type but by the individual
aircraft number. This method worked fine as long as visual observations
were being made. The recorded data could not be correlated with the
flight number provided by the airbase.
For the twenty four hour period the number of flights using the corridor
were eighty eight, while only fifty two exceeded the noise measurement
system of 65 dB(A). This means that regardless of the type of helicopter
or direction of travel, only slightly more than 50% exceeded the 65 dB(A)
level. This did result in noise exposure of up to a maximum of 85 dB(A)
and interuption in conversations for approximately 30 seconds.
The study did show that when visual observations were being made, accurate
measurements were obtained. When recorded measurements were used the noise
exposure could not be determined.

It is recommended that because of the importance of this no.ise intrusion
additional monitored studies should be made.

adopted. Pursuant to State Planning Law, the legislative body may, if it deems
it to be in the public interest, amend the various elements of the General
Plan. Submitted for the Commission's consideration is an amended copy of the
Noise Element which, as a house -keeping item, should be forwarded to the City
Council with a recommendation for adoption.
DISCUSSION:
In accordance with State planning law, the revised Noise Element addresses
several distinct areas of concern. Generally., the Element identifies present
and potential noise sources, noise sensitive areas, and establishes policies and
objectives on how the city should deal with noise related matters.
Information collected for this document came from a variety of sources, but some
specific sources should be noted. Definitions contained in the Element are
those used by the Office of Noise Control, California Department of Health.
Noise contours established for arterial highways within the city were developed
in cooperation with Orange County Environmental Health, as was the 24 hour study
of the'Browning Corridor. Finally, noise contours projected for transportation
systems in East Tustin were prepared as a part of EIR 85-2 by Michael Brandman
Associates.

CONCLUSIONS:
In that the revised edition of the Noise. Element more accurately, reflects
existing and potential noise related conditions than does the previous edition,
and since it has been drafted in conformance with applicable State law, it is
recommended that the Commission. adopt Resolution *No. 2310 forwarding the Noise
Element to the City Council for final approval.
