DATE: February 20, 1998 (City Council Meeting of 3/4/98)
SUBJECT: CONSIDER ADOPTION OF AN UPDATE TO THE NOISE ELEMENT OF
THE GENERAL PLAN AND AMENDMENT OF THE MUNICIPAL CODE
TO ADD CHAPTER,17.53 - NOISE ORDINANCE, WHICH WILL
IMPLEMENT THE NOISE ELEMENT AND ESTABLISH STANDARDS
AND PROCEDURES TO CONTROL NOISE IN THE CITY OF
MOORPARK (GENERAL PLAN AMENDMENT 97 -04 AND ZONING
CODE AMENDMENT 97 -07)
Background
On January 12, 1998, The Planning Commission adopted two resolutions recommending to the
City Council approval of an updated Noise Element and additions to the Municipal Code to
regulate noise. Resolution No. PC -98 -349 approved by a 3 -1 vote (Acosta -no) recommends
approval of the updated Noise Element of the General Plan. Resolution No. PC -98 -350 approved
by a unanimous vote recommends the addition of Chapter 17.53 to the Municipal Code providing
regulations concerning noise, which will assist in the implementation of the Noise Element. The
Planning Commission arrived at their decision following consideration of a written report and
Draft Noise Element and Noise Ordinance prepared by Community Development Department.
No one gave public testimony and no written testimony was submitted. The Planning
Commission recommended an organizational adjustment, where the threshold criteria for noise
levels that constitute a violation were moved from Section 17.53.070 III Paragraph G -K to
Section 17.53.070 I Paragraph A -I. No changes on meaning, content, or enforcement would
result, however the reader's understanding of ordinance criteria was improved.
Discussion
The Noise Element is one of seven mandatory elements required under State Law to be included
in a General Plan. The purpose of the Noise Element is to identify and evaluate noise sources
and problems in the community. It is also part of the information base for decision making on
the location and distribution of land uses. Identifying noise generators and their impact on the
community is an important factor affecting the livability of the community.
The current Noise Element was adopted in 1987, when the population of Moorpark was 17,561.

Honorable City Council
Update to the Noise Element
February 20, 1998
Page 2
However, after significant growth, with a population nearing 30,000, physical conditions have
changed resulting in higher ambient noise levels. Ambient noise is the normal or existing level
of environmental noise from all sources at a location. Automobile traffic is the single highest
generator of noise in the community with projections along Los Angeles Avenue, State Routes
118 and 23, and increasing by five decibels by 2010 as compared to 1994 levels.
The Noise Ordinance was prepared using the State of California Model Noise Ordinance, and
includes maximum recommended noise levels by the type of land use. The proposed ordinance
also establishes noise levels for stationary equipment as well as standards for limited use of
various types of noise producing equipment and machinery.
The other aspect of the proposed Noise Ordinance involves the measurement of noise and
enforcement of those regulations proposed to be adopted.
Environmental Determination
This project is Exempt from provisions of the California Environmental Quality Act under
CEQA requirements pursuant to CEQA Guidelines Section 15061 (b) (3).
Recommendation
1. Adopt Resolution No. 98 - approving the updated Noise Element as an
amendment to the City of Moorpark General Plan.
2. Approve Introduction for first Reading of Ordinance No. amending the
Moorpark Municipal Code by adding Chapter 17.53 titled Noise Ordinance.

1.0 INTRODUCTION
Within the City of Moorpark are a number of transportation related noise sources including
freeways, major and minor arterial roadways as well as a railroad line. The existing noise
corridors within the City, include; State Route 118 (SR 118), State Route 23 (SR 23) and
the Southern Pacific Rail Road (SPRR). In the future, a SR 118 bypass arterial and a SR
23 bypass arterial are proposed to be constructed within the City's boundaries. Effective
strategies to reduce their influence on the community noise environment are an appropriate
and essential part of the Noise Element.
Information relative to the existing and forecast noise environment within Moorpark should
be integrated into future land use planning decisions. The Element provides an analysis
of the noise environment in order that the City may include noise impact considerations in
land development programs.
Residential land uses and areas identified as noise sensitive should be protected from
excessive noise generated by transportation and non - transportation noise sources. The
impacts of transportation noise are most effectively mitigated through the application of
noise standards, goals and implementation strategies established in the Noise Element,
whereas the impacts of non - transportation noise are most effectively abated through the
enforcement of City noise ordinances or regulations.
Noise, as it has been simply defined, is "unwanted sound ". It is an undesirable
byproduct of transportation elements and industrial, commercial and recreation
activities within the community that affects man's environment and causes disturbance.
Physical health, psychological stability, social cohesion, property values, and economic
productivity are factors negatively affected by excessive amounts of noise. The full
effect of such noise on the individual and the community will vary with its duration, its
intensity, and the tolerance level of the individual.

1.1 OVERVIEW
The Noise Element of a General Plan is a comprehensive program for including noise
attenuation measures in the planning process. It is a tool for local planners to use to
achieve and maintain compatible land use based upon acceptable environmental noise
levels. The Noise Element identifies noise sensitive land uses and noise sources, and
defines areas of noise impact for the purpose of developing programs to insure that
Moorpark residents will be protected from excessive noise intrusion.
The Noise Element follows the revised State guidelines in Government Code Section
65302(f) of the Health and Safety Code (described in more detail in the Technical
Appendix Page A -1). The Element quantifies the community noise environment in terms
of noise exposure contours for both near and long -term levels of growth and traffic activity.
The information contained in this document provides the framework to achieve compatible
land uses.
The Element is divided into six sections, including four subsections and an Appendix.
1.0 INTRODUCTION - identifies the noise issues in the City that are to be addressed
within the Noise Element.

1.2 AUTHORIZATION
Recognizing the increasing human environmental impacts of noise pollution and the impact
that local agency land uses and circulation plans have on the community's environmental
quality, the State of California, has mandated that a noise element be included as part of
City and County general plans. Guidelines have been prepared as a result of State
Government Code Section 65302(f) of the Health and Safety Code (described in more
detail in the Technical Appendix A Page A -1), concerning the specific requirements for a
Noise Element which are responsive to State guidelines. Within the City of Moorpark, the
Community Development Department is responsible for the coordination of all local sound
attenuation and regulatory activities.
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 6
1.3 PURPOSE-
The purpose of the Noise Element is to serve as an official guide to the City Council, the
Planning Commission, City departments, individual citizens, businessmen, and private
organizations concerned with noise pollution within the City of Moorpark. The Noise
Element provides a reference to be used in connection with actions on various public and
private development matters as required by law, and is utilized to establish uniformity of
policy, as well as direction within the City concerning actions to minimize or eliminate
excessive noise through the enforcement of community noise standards and ordinances,
and for making decisions regarding proposals which may have an impact on the City's
environment.
The Noise Element includes definitions, objectives, policies, standards, criteria, programs,
and maps which are to be considered when decisions are made affecting the noise
environment within the City of Moorpark.
The objective of the Noise Element is to establish noise standards, and implement policies
and goals to limit to acceptable levels the noise that is created because of transportation
activities, as well as stationery sources. The purpose of the noise ordinance is to adopt
standards that identify a maximum acceptable level of noise that may be generated by
people, machinery or actively before enforcement action may be appropriate to protect
Moorpark residents from excessive noise intrusion.

1.4 DEFINITIONS
The following common terms are used throughout the Noise Element:
Ambient Noise - The composite of noise from all sources near and far. In this context,
the ambient noise level constitutes the normal existing level of environmental noise at a
given location.
Amplitude - A measure of the difference between atmospheric pressure (with no sound
present) and the total pressure (with sound present). Although there are other measures
of sound amplitude, sound pressure is the decibel (dBA).
A- Weighted Sound Pressure Level, dBA (A) - The sound pressure level, in decibels, as
measured on a sound level meter using the A- weighting filter network. The 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.
Equivalent Sound Level (LEQ) - The sound level corresponding to a steady noise level
over a given sample period with the same amount of acoustic energy as the actual time
varying noise level. The energy average noise level during the sample period.
Community Noise Equivalent Level (CNEL) - The average, equivalent A- weighted
sound level during a 24 -hour day obtained by adding five decibels to the hourly noise
levels measured during the evening (from 7:00 p.m. to 10:00 p.m.) and by adding ten
decibels to the hourly noise levels measured during the night (from 10:00 p.m. to 7:00
a.m.). In this way, CNEL takes into account the lower tolerance of people for noise during
the evening and nighttime periods.
Day Night Noise Level (LDN) - Similar to CNEL, except that the evening hours are not
penalized. The LDN is slightly less stringent than the CNEL.
Decibel (dBA) - A unit for describing the amplitude of sound, equal to 20 times the
logarithm to the base 10 of the ratio of the pressure of the sound measured to the
MOORPARK NOISE ELEMENT - MDec9711:24 PM PAGE 8
reference pressure, which is 20 micropascals. Because they are logarithmic, decibels are
not additive. If two similar noise sources produce the same amount of noise (say 100 dBA
each), the total noise level will be 103 dBA, not 200 dBA. An increase in noise level of 10
dBA is generally perceived as being twice as loud.
Exterior Living Space - Open area designed for outdoor living and/or recreation which
has a minimum dimension in any direction of at least 10 feet and excluding required front
and side setback requirements.
Maximum Noise Level - The maximum instantaneous noise level that occurs during a
specific time interval. In acoustics, the maximum sound pressure level is understood to be
for single events unless some other kind of level is specified.
Noise - Annoying, harmful, or unwanted sound.
Noise Barrier - A structure designed to mitigate the impact generated by a noise source
(e.g., an arterial or rail line) at an adjacent noise sensitive location. Barriers should be
continuous structures (without gaps) or designed to achieve the same practical effect and
should be constructed of a material that is impervious to noise (e.g., concrete block,
stucco -on -wood, wood -on -wood, 1/4' tempered plate glass, earthen berm, or any
combination of these or similar materials).
Noise Contour - A line drawn about a noise source indicating constant levels of noise
exposure. CNEL is the metric utilized herein to describe community exposure to noise.
Noise Impact Area - A specific area exposed to significant levels of noise.
Noise Reduction - The ability of a material to reduce the noise level from one place to
another or between one room and another. Noise reduction is specified in decibels.
Noise - Sensitive Land Uses - Noise - sensitive land uses include, but are not limited to,
residences, schools, libraries, hospitals, churches, offices, hotels, and motels. These typify
land uses where suitability is restricted by intrusive noises. Hence, they are termed
"noise- sensitive ". Noise - sensitivity factors include interference with speech

communication; subjective judgement of noise acceptability and relative noisiness, need
for freedom from noise intrusion, and sleep interference criteria. The Land Use Element
of the General Plan provides a description of the residential areas throughout the City and
is considered the source for the inventory of noise - sensitive areas.
Sound - As used herein, sound is a reaction in the ear caused by radiant energy being
transmitted from a source by longitudinal pressure waves in air or some other elastic
medium.
Sound Level Meter - A measurement instrument containing a microphone, an amplifier,
an output meter, and one or more frequency weighting networks. It is used for the
determination of sound levels.
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 10

2.0 EXISTING CONDITIONS
In the City of Moorpark there are four major sources of noise:
1. Traffic on State Routes 118 and 23
2. Traffic on arterials and local collector roadways
3. Rail traffic on the Southern Pacific rail line
4. Commercial, industrial and recreational activities adjacent to residential locations.
Of these, the most serious problems are the noise levels produced by operations on the
State highways, traffic on the major and secondary arterials, and by the railroad. A CNEL
of 70 dBA or greater exists at some residential locations as a result of these sources. An
exterior noise level of 70 dBA or greater exceeds the design noise standard for residential
land uses.
The Noise Element has identified a number of noise related problems and issues within the
City. The policy program consists of policies and implementation techniques that minimize
these problems and issues. Short-term possibilities for noise reduction in Moorpark consist
mostly of the enforcement of noise control guidelines and the appropriate placement of
walls and berms to buffer residential and other noise - sensitive areas from traffic noise.
Long -term possibilities for noise reduction will be contingent upon future development,
especially along major traffic routes, and in the vicinity of the railroads. Planning for these
situations can help to minimize the future impact of noise on the community.
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 11
3.0 NOISE EVALUATION AND MEASUREMENT
A description of the character of a particular noise requires the following:
1. The amplitude and amplitude variation of the acoustical wave,
2. The frequency (pitch) content of the noise, and
3. The duration of the noise.
Definitions of the most commonly used terms encountered in community noise
assessments and noise control have been provided as part of the Noise Element. Of these
terms, the A- weighted sound pressure level (identified as dBA {A }) is the scale of
measurement that is most useful in community noise measurement. This sound level is
measured in decibels to provide a scale with the range and characteristics most consistent
with that of people's sensitivity to sounds.
The A- weighted sound level, its application to the CNEL measure of noise exposure, and
its utility in the description of ambient noise levels are discussed in the remainder of this
section.
To establish the A- weighted sound level, the acoustical signal is detected by the
microphone and then filtered to weight those portions of the noise that are most
annoying to individuals. This weighting of sound energy corresponds approximately
to the relative annoyance experienced by humans from noise at various
frequencies. The sound levels of a few typical sources of noise that are routinely
experienced by people within the City of Moorpark are listed in Figure NO. 1.
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 12
00CC`L
The A- weighted -sound level of traffic noise and other long -term noise producing activities
within and around a community varies considerably with time. Measures of this varying
noise level are accomplished by obtaining statistical samples. For the purposes of this
study, the following statistical values have been used:
L90 - The near minimum sound level. This value is exceeded 90% of the time during the
measurement period.
L50 - The central tendency of the sound level. This value is exceeded 50% of the time
during the measurement period.
L10 - The near maximum sound level. This value is exceeded 10% of the time during the
measurement period.
Leq - The energy equivalent sound level. This value is most representative of the
long -term annoyance potential as well as other effects of the noise.
These measures may be recorded to obtain representative samples of the noise during
certain time periods (e.g., peak traffic period, morning, afternoon, night, etc.).
It is recognized that a given level of noise may be more or less tolerable depending on the
duration of exposure and the time of day during which the noise is experienced. There are
several measures of noise exposure that consider not only the variation of noise level but
also include temporal characteristics. Of these, the State Department of Aeronautics and
the California Commission of Housing and Community Development have adopted the
CNEL. This measure weights the average noise level for the evening hours (from 7:00
p.m. to 10:00 p.m.) by 5 dBA, and the late evening and early morning hours (from 10:00
p.m. to 7:00 a.m.) by 10 dBA. The unweighted daytime noise levels are combined with
these weighted levels and averaged to obtain a CNEL value. Figure 2 indicates the
outdoor CNEL at typical locations throughout the Southern California area.

The CNEL scale is considered acceptable for establishing noise criteria for transportation
related noise for various land use categories. In general, exterior noise exposures at
residential locations should not exceed a CNEL of 65 dBA.
The Environmental Protection Agency (EPA) has recommended a policy stating that a
CNEL of 55 dBA not be exceeded within exterior living spaces. However, the EPA
emphasizes that this level of exposure may not be economically feasible nor, in many
cases, a practical level to achieve.
Acceptable Interior Noise Exposures NEB
California's noise insulation standards were officially adopted by the California Commission
of Housing and Community Development in 1974 and became effective on August 22,
1974 (California Administrative Code, Title 25, Section 1092). The ruling states that
"Interior community noise equivalent level (CNEL) with windows closed, attributable to
exterior sources shall not exceed an annual CNEL of 45 dBA in any habitable room."
Additionally, the commission specifies that residential buildings or structures to be located
within exterior CNEL contours of 60 dBA or greater of an existing or adopted freeway,
expressway, parkway, major street, thoroughfare, rail line, rapid transit line, or industrial
noise source shall require an acoustical analysis showing that the building has been
designed to limit intruding noise to an interior CNEL of 45 dBA.
In general, noise may affect the average individual in the following ways:
1. General hearing loss or damage. Sound levels which exceed 85 dBA(A), when
experienced for long durations during each working day, may result in severe
temporary or even permanent hearing loss. State and federal safety and health
regulations currently protect workers at levels of exposure that exceed 90 dBA(A) for
each 8 -hour workday. Community noise levels are sufficiently low so as to not cause
hearing loss.
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 16
2. Interference with oral communication. Speech intelligibility is impaired when sound
levels exceed 60 dBA(A). The amount of interference increases with sound level and
distance between speaker and listener.
3. Sleep interference. Sound levels that exceed 40 to 45 dBA(A) are generally
considered excessive for sleeping areas within a residence.
4. Contributes to nervousness and tension. Human response to frequent noise loud
enough to startle or alarm has been linked to such chronic symptoms as low
resistance, high blood pressure, exhaustion, and ulcers.

4.0 FINDINGS
The noise survey contained in the Technical Appendix reveals that the noise environment
at locations throughout the City are primarily attributable to transportation corridors. The
transportation noise sources in the City of Moorpark can be divided into three basic
categories: freeways, major and minor arterial roadways, and railroad sources. Each of
the transportation sources and their impacts on the noise environment of Moorpark are
summarized in the following paragraphs.
Freeways - The City of Moorpark has two freeways currently within its boundaries, State
Route 118 (SR 118) and 23 (SR 23). The SR 118 and SR 23 currently pass through the
City as conventional highways.
The SR 118 runs in an east/west direction within the City and terminates at its connection
with the SR 23 Freeway. Currently, two surface streets, New Los Angeles Avenue and Los
Angeles Avenue serve as SR 118. There are a number of residential areas located along
SR 118, and those homes directly adjacent to the highway are exposed to noise levels in
excess of 65 CNEL. In addition, there are two existing schools along Los Angeles Avenue,
however, the school buildings are set back from the roadway and are exposed to noise
levels less than 65 CNEL.
Moorpark Avenue and Walnut Canyon Road, currently, serve as SR 23. A large portion
of the land uses in the southeast area of the City adjacent to this arterial corridor is open
space; however, there are also existing residential units in the Varsity Park neighborhood.
Noise levels in excess of 65 CNEL currently occur at those units adjacent to the corridor
in the Varsity park neighborhood.
A SR 118 bypass arterial is proposed to be constructed in the future. The future SR 118
is proposed to run through the northern section of the City and will redirect traffic traveling
through the City. Land area, predominantly in the northwest portion of the City adjacent

to proposed SR 118 is mostly undeveloped and is designated for future residential land
uses by the Land Use Element. The noise associated with the future SR 118 will be
significant, and the residential homes located adjacent to the proposed corridor may be
exposed to future traffic noise in excess of 70 CNEL.
There are also plans to build a SR 23 bypass arterial within the City's boundaries. The SR
23 will run in the north /south direction through the City. Based upon the current Land Use
Element there will be limited residential land uses in close proximity to this future arterial.
New residential areas should include sufficient noise mitigation measures to attenuate the
projected noise from the SR 23.
Major and Minor Arterial Roadways - Traffic noise from major thoroughfares is a
significant source of noise within the community. The current and future major roadways
in the City include: Los Angeles Avenue, New Los Angeles Avenue, High Street, Tierra
Rejada Road, Walnut Canyon Road, Campus Park Drive, Moorpark Avenue, Spring Road,
Science Drive, Princeton Avenue and Collins Drive.
Noise levels along roadways are determined by a number of traffic characteristics. Most
important is the average daily traffic (ADT). Additional factors include the percentage of
trucks, vehicle speed, the time distribution of this traffic and gradient of the roadway.
In general, many of the land uses along the arterial roadways are commercial and
industrial. However, there are a number of single family homes that are located adjacent
to arterials.
Railroad - The railroad within the City is another significant source of noise. The Southern
Pacific Railroad (SPRR) is the rail line that runs in the northeast/southwest direction. The
SPRR is owned and operated by the Southern Pacific Transportation Company. Currently,
approximately 33 train operations per day run through the City. There are a number of
existing residential land uses located along this railroad. The limited number of residences
directly adjacent to the railroad are impacted by noise levels in excess of 70 CNEL.

5.0 GOAL STATEMENT
The goal of the Noise Element is to ensure that the health and well being of the citizens
of Moorpark are not compromised by exposure to excessive and possibly harmful levels
of noise. This will serve to provide a quality environment in which the citizens of Moorpark
may live and have assurance of continued health and well- being.
The sections that follow, provide a discussion of the methods used to measure and
analyze the noise environment of the City of Moorpark. The results of the analysis will then
be compared with accepted standards to determine where the City is affected by adverse
levels of noise. This will lead to a description of a policies and implementation programs
designed to minimize (or eliminate) these adverse levels and prevent future problems from
occurring.

6.0 GOALS, POLICIES, AND IMPLEMENTATION
Goal N -1: Protect the health, safety, and general welfare of the public from adverse noise
impacts.
Policy N -1.1: Identify sound attenuation measures that can be applicable to transportation
related noise impacts.
Policy N -1.2: Incorporate noise considerations into land use planning decisions to prevent
or minimize future noise and land -use incompatibilities. The analysis of traffic and other
noise sources shall consider future conditions at General Plan build out.
Policy N -1.3: Provide for reduction in noise impacts from non - transportation sources
through adoption of a Noise Ordinance, which is intended to protect people from noise
generated on adjacent properties.
Policy N -1.4: Require stationary noise sources to limit noise to levels that do not interfere
with adjacent uses.
Policy N -1.5: Require new projects to contribute to the mitigation of off -site traffic noise
impacts to the extent that these impacts are generated by the proposed project.
Policy N -1.6: Limit the impact of nuisance noise sources upon residential areas.
Implementation N- 1.1.1: The City shall require the use of appropriate sound attenuation
measures such as: walls, berms, setbacks and construction techniques, in the design of
new residential or other noise sensitive land uses adjacent to existing or planned
transportation corridors. The noise level criteria identified by Table 2.
Implementation N- 1.1.2: The City shall seek to minimize transportation noise through the
use of sound attenuation design features and coordination of transportation routing. As
part of the evaluation of commercial and industrial projects, truck movements and routes
in the City shall be evaluated to provide effective separation from residential or other noise
sensitive land uses. (For example: adding truck traffic to an arterial with adjacent
commercial and /or industrial development along the roadway creates less of a relative
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 21
noise impact than adding the truck traffic to a smaller roadway, such as a collector, where
the land use is predominantly residential.)
Implementation N- 1.1.3: The City shall encourage rail traffic operators to provide
appropriate mitigation for noise impacts resulting from increased rail traffic.
Implementation N- 1.1.4: Residential locations adjacent to rail lines are exposed to noise
in the range of 90 to 110 dBA(A) during train pass by. The installation of noise barriers
should be considered as a noise reduction measure for new residential development
adjacent to the railroad tracks.
Implementation N- 1.1.5: The City shall encourage the enforcement of State Motor Vehicle
noise standards for all privately owned, City owned, and City operated automobiles, trucks,
and motorcycles within Moorpark through coordination with the California Highway Patrol
and City of Moorpark Police Department.
Implementation N- 1.1.6: The construction of noise barriers should be considered as a
noise reduction measure to screen private outdoor residential yard areas from new arterial
road widening projects, which result in a significant noise level increase.
Implementation N- 1.2.1: Sound attenuation measures should be considered early in the
development of new residential or noise sensitive uses. The location and orientation of the
residential buildings should be configured to minimize or eliminate a noise problem for a
site adjacent to the freeway, highways, arterials, or rail lines. Other effective noise
reduction tools include the use of earthen berms, sound reducing walls, and generous
setbacks.
Implementation N- 1.2.2: New residential development that may occur within areas
identified on Exhibits 10 and 11 of the Noise Element Technical Appendices as having an
existing or projected CNEL of 60 dBA or greater shall be required to have a noise study
performed to determine the level of sound attenuation required to meet acceptable interior
and exterior noise levels identified in Table 2. The noise study shall be conducted by a
person qualified and experienced in performing such studies which may be demonstrated
in a variety of ways including; membership in the Institute of Noise Control Engineers
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 22
(INCE) or as a Registered Professional Engineer in the State of California. This acoustical
analysis shall indicate the existing and projected CNELs on the site and the method(s) by
which the noise is to be controlled or reduced for residential projects to no more than 65
dBA within the exterior living space and no more than 45 dBA within the interior living
space of the project.
Implementation N- 1.2.3: The City shall employ standards that identify acceptable limits
of noise for various land uses throughout the City including residences, schools, hospitals,
convalescent homes, libraries, parks, and other noise sensitive areas. These criteria are
designed to fully integrate noise considerations into land use planning to prevent new
noise /land use conflicts. Table 1 shows criteria used to assess the compatibility of
proposed land uses with the noise environment. These criteria are the basis for the
development of specific Noise Standards. These criteria will also be evaluated at the
zoning stage to determine the appropriateness of a proposed land use and appropriate
conditions of approval that may be imposed on a project. The Noise Standards, presented
in Table 2, defines the City policies related to land uses and acceptable maximum noise
levels. Tables 1 and 2 are the primary tools that allow the City to ensure noise integrated
planning for compatibility between land uses and outdoor noise. The City should require
that all proposed new projects within it boundaries, demonstrate compliance with the
standards in Table 2 at the time of project application.
Implementation N- 1.2.4: The City shall continue to enforce the State of California Uniform
Building Code provision that specifies that the indoor noise levels for residential living
spaces not exceed 45 dBA CNEL, due to the combined effect of all noise sources. The
State requires implementation of this standard when the outdoor noise levels exceed 60
dBA CNEL. The Noise Referral Zones (60 dBA CNEL) can be used to determine when this
standard needs to be addressed. The Uniform Building Code (specifically, the California
Administrative Code, Title 24, Part 6, Division T25, Chapter 1, sub chapter 1, Article 4,
Section T25 -28) requires that "Interior community noise levels (CNEL/LDN) with windows
closed, attributable to exterior sources shall not exceed an annual CNEL or LDN of 45 dBA
in any habitable room." The code requires that this standard be applied to all new hotels,
motels, apartment houses and dwellings other than detached single - family dwellings. The
City shall also apply this standard to new single - family dwellings, by amending the
Municipal Code to include this requirement.
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 23
00CANS4 f
Implementation N- 1.2.4: The City should require that the State of California Noise
Insulation Standards (State Building Code, Part 2, Title 24, Section 3501) be applied to all
new multi - family and condominium conversion projects. The City shall require that, prior
to issuance of building permits, the applicant demonstrate that the design of the structure
will adequately isolate noise between adjacent units (party walls and common
floor /ceilings) per Chapter 35 of the Uniform Building Code. This Code requires that all
common wall assemblies be designed to a Class (STC) rating of at least 50, and that all
common floor /ceiling assemblies be designed to achieve at least an STC of 50 and an
Impact Isolation Class (IIC) rating of 50.
Implementation N- 1.3.1: The City shall adopt a new comprehensive noise ordinance to
ensure that City residents are not exposed to excessive noise levels from stationary noise
sources. The purpose of the ordinance is to protect people from non transportation related
noise sources such as people, machinery, commercial and industrial activities. The noise
ordinance does not apply to motor vehicle noise on public streets or to the railroad line.
The noise ordinance is designed to protect quiet residential areas (or other land uses
requiring quiet, such as hospitals, convalescent homes, schools, etc.) from stationary noise
sources. Land uses are determined by their actual use and not by the current zoning
designation. All new noise sources would be required to meet the noise ordinance at the
time of construction. Existing stationary noise sources would be given an amortization
period to be brought into compliance. The Noise Ordinance compliance and enforcement
shall be determined for each application by City staff.
Implementation N- 1.3.2: All new building permits will be issued based on compliance with
the noise criteria in the Noise Ordinance. A specific set of conditions shall be developed
for the issuance of building permits that include mechanical equipment. Maximum noise
levels shall be identified and noise sensitive areas of residential properties defined with
compliance demonstrated prior to the issuance of building permits.
Implementation N- 1.3.3: All new development projects, including but not limited to
planned development and conditional use permits, shall be conditioned to comply with the
noise limits in the Noise Ordinance and Noise Element standards. A specific set of
conditions shall be developed for such projects that include any use that may cause noise
impacts on residential areas. This includes, but is not limited to, restaurants, bars,
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 24
entertainment, parking facilities, industrial and commercial uses. Maximum noise levels
shall be identified and noise sensitive areas of residential properties defined with
compliance demonstrated prior to the approval of the development project. Restaurants,
bars, and other entertainment type uses may be subject to a condition of approval that
requires that operators of a facility with a noise violation history be required to conduct on
site noise monitoring to verify compliance with the noise limits found in the Noise
Ordinance.
Implementation N- 1.3.4: Enforcement of the Noise Ordinance shall be the responsibility
of the Code Enforcement staff of the Community Development Department. The most
effective method to control community noise impacts from non - transportation sources is
through application of the community Noise Ordinance. It shall be the Policy of the City
to notify applicants for building permits that include mechanical equipment, of the existence
of the Noise Ordinance. Typical examples would include commercial and industrial areas
near residential development. The City may require as a condition of project approval,
that noise measurement data be provided to the City after construction, demonstrating
compliance with the Noise Ordinance.
Implementation N- 1.4.1: The City shall enforce the Municipal Code provisions relating
to the time that limitations that construction activity in or adjacent to residential areas may
occur in order to reduce the intrusion of noise in the early morning and late evening hours,
on weekends and holidays. At the time of development project approval, the City shall
ensure, through conditions of approval, that adequate noise control measures at all
construction sites are provided (through the provisions of mufflers and the physical
separation of machinery maintenance areas from adjacent residential uses).
Implementation N- 1.4.2: The City shall establish and maintain coordination among the
City agencies involved in noise abatement and ensure the continued application of noise
enforcement efforts of the City through the Code Enforcement Officer and the Police
Department.
Implementation N- 1.4.3: As a condition of development, the City shall limit delivery hours
for stores with loading areas or docks fronting, siding, bordering, or gaining access on
driveways adjacent to noise sensitive uses. Exemption from this restriction should be
MOORPARK NOISE ELEMENT - 18Dec9711:24 PM PAGE 25
based on compliance with the nighttime noise limits established by the Noise Ordinance.
Grocery stores are a major concern for late night delivery noise. The City shall consider
limiting delivery hours as a condition of approval for such projects when noise sensitive
uses are within 100 feet of loading areas, unless the noise level is within the limitations
identified by the Noise Ordinance. The City may consider potential effects of such limits
relative to increasing peak hour truck movements. In particular the City shall consider, in
determining limits on delivery hours, if such limits will result in increased peak hour truck
movements and corresponding potential increases in air quality impacts.
Implementation N- 1.4.2: The City shall establish and enforce the noise ordinance
standards or noise limits, and restrict the hours of maintenance or construction activity in
or adjacent to residential areas that result from in -home hobby or work related activities.
Implementation N- 1.5.1: The City shall adopt a new comprehensive Noise Ordinance to
ensure that City residents are not exposed to excessive noise levels from stationary noise
sources. The purpose of the Noise Ordinance is to protect people from non - transportation
related noise sources such as outdoor recreation people, machinery, commercial and
industrial activities. The Noise Ordinance does not apply to motor vehicle noise on public
streets or to the railroad lines. The Noise Ordinance is designed to protect residential
areas (or other noise sensitive land uses such as hospitals, convalescent homes, etc.) from
stationary noise sources. Land uses are determined by their actual use and not by the
current zoning designation. All new noise sources would be required to comply with the
Noise Ordinance criteria at the time of construction. Existing noise sources would be given
a two (2) year period to achieve consistency with the ordinance. The Noise Ordinance
compliance and enforcement shall be designed for easy application by City staff.

INTERPRETATION
ZONE A Specified land use is satisfactory, based upon the assumption that any
CLEARLY COMPATIBLE buildings involved are of normal conventional construction without
any special noise insulation requirements.
ZONE B New construction or development should be undertaken only after detailed
NORMALLY COMPATIBLE analysis of the noise reduction requirements are made and needed
noise insulation features in the design are determined. Conventional
construction, with closed windows and fresh air supply systems or air
conditioning, will normally suffice.
ZONE C New construction or development should generally be discouraged. If new
NORMALLY INCOMPATIBLE construction or development does proceed, a detailed analysis of noise
reduction requirements must be made and needed noise insulation features
included in the design
ZONE D New construction or development should generally not be undertaken.

TECHNICAL APPENDIX
1.0 NOISE ELEMENT REQUIREMENTS
The State of California has mandated that each county and city prepare a Noise Element as pan
of its General Plan. Section 65302(f) of the California Government Code specifically requires:
(f) A Noise Element shall identify and appraise noise problems in the community.
The noise element shall recognize the guidelines established by the Office of Noise
Control in the State Departmentof Health Services and shall analyze and quantify, to
the extent practicable, as determined by the legislative body, current and projected
noise levels for all of the following sources:
1. Highways and freeways.
2. Primary arterials and major local streets.
3. Passenger and freight on -line railroad operations and ground rapid transit systems.
4. Commercial, general aviation, heliport, helistop, and military airport operations,
aircraft overflights, jet engine test stands, and all other ground facilities and
maintenance functions related to airport operation.
S. Local industrial plants, including, but not limited to, railroad classification yards.
6. Other ground stationary noise sources identified by local agencies as contributing
to the community noise environment.
Noise contours shall be shown for all of the sources and stated in terms of
community noise equivalent level (CNEL) or day -night average level (LDN). The
noise contours shall be prepared on the basis of noise monitoring or following
generally accepted noise modeling techniques for the various sources identified in
paragraphs (1) to (6), inclusive. The noise contours shall be used as a guide for
establishing a pattern of land uses in the land use element that minimizes the exposure
of community residents to excessive noise. The Noise Element shall include
implementation measures and possible solutions that address existing and foreseeable
noise problems, if any. The adopted noise element shall serve as a guideline for
compliance with the state's noise insulation standards.
CITY OF MOORPARK NOISE ELEMENT TECHNICAL APPENDIX PAGE A - 1 3 E
Appendix A of the State of California General Plan Guidelines (The State Guidelines for
Preparation and Content of Noise Elements of the General Plan) indicates that the Noise
Element should present the noise environment in terms of noise contours. For those areas
identified as containing noise - sensitive facilities, the noise environment is determined by
monitoring. The purpose of this Technical Appendix is to provide background and supporting
information for the City of Moorpark Noise Element. This Appendix contains background
information on noise, information on the health effects of noise, noise assessment criteria,
methodology in determining the noise environment, measurement and modeling results, and a
glossary (beginning on page C -1).
2.0 BACKGROUND ON NOISE
2.1 Noise Definitions
Sound is technically described in terms of the loudness (amplitude) and frequency (pitch) of
the sound. The standard unit of measurement of the loudness of sound is the Decibel (dB).
Since the human ear is not equally sensitive to sound at all frequencies, a special frequency-
dependent rating scale has been devised to relate noise to human sensitivity. The A- weighted
decibel scale (dBA) performs this compensation by discriminating against frequencies in a
manner approximating the sensitivity of the human ear.
Decibels are based on the logarithmic scale. The logarithmic scale compresses the wide range
in sound pressure levels to a more usable range of numbers in a manner similar to the way that
the Richter scale is used to measure earthquakes. In terms of human response to noise, a sound
10 dBA higher than another is judged to be twice as loud; and 20 dBA higher four times as
loud; and so forth. Everyday sounds normally range from 30 dB (very quiet) to 100 dB (very
loud). Examples of various sound levels in different environments are shown in Exhibit 1.
Sound levels decrease as a function of distance from the source as a result of wave divergence,
atmospheric absorption, and ground attenuation. As the sound wave form travels away from
the source, the sound energy is spread over a greater area, dispersing the sound power of the
wave. Atmospheric absorption also influences the levels that are received by the observer. The
greater the distance traveled, the greater the influence and the resultant fluctuations. The degree
of absorption is a function of the frequency of the sound as well as the humidity and
temperature of the air. Turbulence and gradients of wind, temperature and humidity also play a
CR7 OF MOORPARK NOISE ELEMENT TECHNICAL APPENDIX PAGE A - 2 .,
significant role in determining the degree of attenuation.
Noise has been defined as unwanted sound and it is known to have several adverse effects on
people. From these known effects of noise, criteria have been established to help protect the
public health and safety and prevent disruption of certain human activities. This criteria is
based on such known effects of noise on people as hearing loss (not generally a factor with
community noise), communication interference, sleep interference, physiological responses
and annoyance. Each of these potential noise impacts on people are briefly discussed in the
following narratives:
HEARING LOSS is, in general, not a concern in community noise problems. The
potential for noise - induced hearing loss is more commonly associated with
occupational noise exposures in heavy industry or very noisy work environments
with long -term exposure. The Occupational Safety and Health Administration
(OSHA) identifies a noise exposure limit of 90 dBA for 8 hours per day to protect
from hearing loss. Noise levels in neighborhoods, even in very noisy airport
environments near major international airports, is not sufficiently loud to cause
hearing loss.
COMMUNICATION INTERFERENCE is one of the primary concerns in environmental
noise problems. Communication interference includes interference with speech and
activities such as watching television. Normal conversational speech is in the range of
60 to 65 dBA and any noise in this range or louder may interfere with speech. There
are specific methods of describing speech interference as a function of distance
between speaker and listener and voice level. Exhibit 2 shows the percent of sentence
intelligibility with respect to various noise levels.
SLEEP INTERFERENCE is a major noise concern in noise assessment and, of course,
is most critical during nighttime hours. Sleep disturbance is one of the major causes
of annoyance due to community noise. Noise can make it difficult to fall asleep, and
can create momentary disturbances of natural sleep patterns by causing shifts from
deep to lighter stages and cause awakening. Noise may even cause awakening which
a person may or may not be able to recall.
Extensive research has been conducted on the effect of noise on sleep disturbance.
Recommended values for desired sound levels in residential bedroom space range
from 25 to 45 dBA with 35 to 40 dBA being the norm. The National Association of
Noise Control Officials have published data on the probability of sleep disturbance
with various single event noise levels. Based on experimental sleep data as related to
noise exposure, a 75 dBA interior noise level event will cause noise induced
awakening in 30 percent of the cases.
PHYSIOLOGICAL RESPONSES are those treasurable effects of noise on people which
are realized as changes in pulse rate, blood pressure, etc. While such effects can be
induced and observed, the extent is not known to which these physiological
responses cause harm or are a sign of harm. Generally, physiological responses are a

reaction to a loud short term noise such as a rifle shot or a very loud jet overflight.
ANNOYANCE is a very individual characteristic and can vary widely from person to
person. What one person considers tolerable can be quite unbearable to another of
equal hearing capability. The level of annoyance, of course, depends on the
characteristics of the noise (i.e.; loudness, frequency spectra, time, and duration),
and how much activity interference (e.g. speech interference and sleep interference)
results from the noise. However, the level of annoyance is also a function of the
attitude of the receiver. Personal sensitivity to noise varies widely. It has been
estimated that 2 to 10 percent of the population is highly susceptible to noise that they
themselves did not generate, while approximately 20 percent are unaffected by noise.
Attitudes are affected by the relationship between the person and the noise source (Is
it our dog barking or the neighbor's dog ?). Whether we believe that someone is
trying to abate the noise will also affect our level of annoyance.
2.2 Noise Metric and Assessment Criteria
Community noise is generally not a steady state and varies with time. Under conditions of non -
steady state noise, some type of statistical metric is necessary in order to quantify noise
exposure over a long period of time. Several rating scales have been developed for describing
the effects of noise on people. They are designed to account for the above known effects of
noise on people.
Based on these effects, the observation has been made that the potential for noise to impact
people is dependent on the total acoustical energy content of the noise. A number of noise
scales have been developed to account for this observation. These scales are: the Equivalent
Noise Level (LEQ), the Day Night Noise Level (LDN), and the Community Noise Equivalent
Level (CNEL). These scales are described in the following paragraphs.
LEQ is the "energy" average noise level during the time period of the sample. It is a
number that represents a decibel sound level. This constant sound level would
contain an equal amount of energy as a fluctuating sound level over a given period of
time. LEQ can be measured for any time period, but is typically measured for 15
minutes, 1 hour or 24- hours.
LDN is a 24 -hour, time- weighted annual average noise level. Time - weighted refers
to the fact that noise which occurs during certain sensitive time periods is penalized
for occurring at these times. In the LDN scale, those events that take place during the
night (10 pm to 7 am) are penalized by 10 dB. This penalty was selected to attempt to
account for increased human sensitivity to noise during the quieter period of a day,
where sleep is the most probable activity.
CNEL is similar to the LDN scale except that it includes an additional 5 dBA penalty

4.2 Noise Contours
The existing and future noise levels in the City were established in terms of the CNEL indices
by modeling all of the traffic noise sources for the existing and future traffic and speed
characteristics. The results for the roadways are presented in tabularized format in the
following tables. The existing contours are presented in Table 3 and the future contours are
presented in Table 4. The data in these tables represent the distance from the centerline of the
road to the contour value shown. Note that these tables do not include the mitigating effect of
noise barriers or topography. The traffic mix assumptions used in this analysis are shown in
Table 5. The existing roadway noise contours are shown graphically in Exhibit 10. These
contours are based on existing traffic volumes that were determined by traffic counts. The
future traffic noise contours are shown graphically in Exhibit 11. These contours are based on
projected traffic volumes supplied by the City of Moorpark.

for events that occur during the evening (7 pm to 10 pm) time period. Either LDN or
CNEL may be used to identify community noise impacts within the Noise Element.
Example noise environments in terms of the CNEL metric are shown in Exhibit 3.
The public reaction to different noise levels varies from community to community. Extensive
research has been conducted on human responses to exposure of different levels of noise.
Exhibit 4 relates LDN noise levels to community response from some of these surveys.
Community noise standards are derived from tradeoffs between community response surveys
and economic considerations for achieving these levels.
Intermittent or occasional noise such as those associated with stationary noise sources is not of
sufficient volume to exceed community noise standards that are based on a time averaged scale
such as the CNEL scale. To account for intermittent noise, another method to characterize
noise is the Percent Noise Level (L %). The Percent Noise Level is the level exceeded X% of
the time during the measurement period. Percent Noise Levels are another method of
characterizing ambient noise where, for example, L90 is the noise level exceeded 90 percent of
the time, L50 is the level exceeded 50 percent of the time, and L 10 is the level exceeded 10
percent of the time. L90 represents the background or minimum noise level, L50 represents
the average noise level, and L 10 the peak or intrusive noise levels. Examples of various noise
environments in terms of the Percent Noise Levels are shown in Exhibit 5.
Noise Ordinances are typically specified in terms of the Percent Noise Levels. Ordinances are
designed to protect people from non - transportation related noise sources such as loud music,
machinery and vehicular traffic on private property. Noise Ordinances apply to motor vehicle
noise on public streets or other transportation - related noise sources that are not preempted by
State or Federal government requirements.
2.3 Noise and Land Use Compatibility Guidelines
The purpose of this section is to present information regarding the compatibility of various land
uses with environmental noise. It is from these guidelines and standards that the City of
Moorpark Noise Criteria and Standards will be developed. Noise/land use guidelines have
been produced by a number of Federal and State agencies including the Federal Highway
Administration, the Environmental Protection Agency, the Department of Housing and Urban
Development, the American National Standards Institute and the State of California. These
guidelines, presented in the following paragraphs, are all based upon cumulative noise criteria
such as LEQ, LDN or CNEL.

MESTRE GREYS ASSOCIATES I Noise Environments in Terms of Percent Noise Levels
In March 1974, the ENVIRONMENTAL PROTECTION AGENCY published a document entitled
"Information on Levels of Environmental Noise Requisite to Protect Public Health and Welfare
With an Adequate Margin of Safety" (EPA 550/9 -74 -004). Exhibit 6 presents a table of land
uses and requisite noise levels. In this table, 55 LDN is described as the requisite level with an
adequate margin of safety for areas with outdoor uses; this includes residences and recreational
areas. The EPA "levels document" does not constitute a standard, specification or regulation,
but identifies safe levels of environmental noise exposure without consideration for economic
cost for achieving these levels.
The FEDERAL HIGHWAY ADMINISTRATION (FHWA) has adopted and published noise abatement
criteria for highway construction projects. The noise abatement criteria specified by the FHWA
are presented in Exhibit 7 in terms of the maximum one -hour Noise Equivalent Level (LEQ).
The FHWA noise abatement criteria basically establishes an exterior noise goal for residential
land uses of 67 LEQ and an interior goal for residences of 52 LEQ. The noise abatement
criteria applies to private yard areas and assumes that typical wood frame homes, with
windows open, provide a 10 dB noise reduction (outdoor to indoor) and a 20 dB noise
reduction with windows closed.
The STATE OF CALIFORNIA requires each city and county to adopt a Noise Element for
inclusion in their General Plans. The Noise Element must contain a noise/land use
compatibility matrix. A recommended (but not mandatory) matrix is presented in the
"Guidelines for the Preparation and Content of Noise Elements of the General Plan," (Office of
Noise Control, California Department of Health, February 1976). Exhibit 8 presents this
recommended matrix.
3.0 METHODOLOGY
The noise environment in Moorpark was modeled using a comprehensive noise measurement
survey of existing noise sources and incorporating these results into computer noise models (it
is, of course, impossible to measure future noise levels so we must rely on computer noise
models for future noise estimates). The noise environment is commonly presented graphically
in terms of lines of equal noise levels, or contours. The following paragraphs detail the
methodology used in the measurements and modeling.
3.1 Measurement Procedure
Twenty-seven sites were selected for measurement of the noise environment in Moorpark. A
review of noise complaints and identification of major noise sources in the community
provided the initial base for development of the community noise survey. The measurement
locations were selected on the basis of proximity to major noise sources and noise sensitivity
of the land use. The measurement locations are depicted in Exhibit 9.

The Moorpark Noise Element measurement survey utilized the Bruel & Kjxr automated digital
noise data acquisition systems for short -term (15 minute) LEQ readings and long term (24
hour) readings. This instrument automatically calculates both the Equivalent Noise Level
(LEQ) and Percent Noise Level (L %) for any specific time period. The noise monitors were
equipped with a Bruel & Kj�er 1/2 inch electret microphone and was calibrated with a Bruel &
Kjxr calibrator with calibrations traceable to the National Bureau of Standards. Calibration for
the calibrators are certified through the duration of the measurements by Bruel & Kjxr. This
measurement system satisfies the ANSI (American National Standards Institute) Standards for
Type 1 precision noise measurement instrumentation.
3.2 Computer Modeling
The traffic noise levels projected in the Noise Element were computed using the Highway
Noise Model published by the Federal Highway Administration ( "FHWA Highway Traffic
Noise Prediction Model," FHWA -RD -77 -108, December 1978). The FHWA Model uses
traffic volume, vehicle mix, vehicle speed, and roadway geometry to compute LEQ noise
levels. A computer code has been written which computes equivalent noise levels for each of
the time periods used in CNEL. Weighting and summing the noise levels results in the CNEL
for the traffic projections used. The traffic data used to project these noise levels are derived
from the City of Moorpark's General Plan Circulation Element. The traffic mix data (i.e., the
vehicle makeup of the traffic on the roadways in terms of percentages of cars, medium trucks,
and heavy trucks) for the arterials are based upon surveys (conducted by the County of
Orange) of roadways in Southern California. The traffic mix information is considered typical
for arterials in the Southern California area and is applicable to the City of Moorpark.
4.0 RESULTS
4.1 Measurement Results
The noise measurement program was conducted over a period of three days. The survey was
taken on March 15th, March 29th, and on April 4th, 1994, at 27 locations throughout the City.
The results of the ambient short -term noise measurements at each site are shown in Table 1.
The results of the long term measurements are shown in Table 2; this table also shows the date
and time of the measurements. The quantities measured were the Equivalent Noise Level
(Leq), the maximum noise level (Lmax) and the Percent Noise Levels (L %).

B. The noise standards for the various categories of land use identified in Table 1 shall,
unless otherwise specifically indicated, apply to all such property within a designated
zone.
C. No person shall operate or cause to be operated, any source of sound at any location
within the City Moorpark or allow the creation of any noise on property owned,
leased, occupied or otherwise controlled by such person, which causes the noise
level when measured on any other property, either incorporated or unincorporated,
to exceed:
1. The noise standard for that land use as specified in Table 1 for a cumulative
period of more than 30 minutes in any hour; or
2. The noise standard plus 5 dB for a cumulative period of more than fifteen
minutes in any hour; or
3. The noise standard plus 10 dB for a cumulative period of more than five
minutes in any hour; or
4. The noise standard plus 15 dB(A) for a cumulative period of more than one
(1) minute in any hour; or
5. The noise standard plus 20 dB(A) or the maximum measured ambient level,
for any period of time.
6. If the measured ambient level differs from that permissible within any of the
first four noise limit categories above, the allowable noise exposure standard
shall be adjusted in 5 dB increments in each category as appropriate to
encompass or reflect said ambient noise level. In the event the ambient noise
level exceeds the fifth noise limit category, the maximum allowable noise
level under this category shall be increased to reflect the maximum ambient
noise level.
D. If the measurement location is on a boundary between two different zones, the noise
level limit applicable to the lower noise zone plus 5 dB(A), shall apply.
E. If possible, the ambient noise shall be measured at the same location along the
property line where the alleged offending noise source is inoperative. If for any
reason the alleged offending noise source cannot be shut down, the ambient noise
must be estimated by performing a measurement in the same general area of the
source but at a sufficient distance such that the noise from the source is at least 10 dB
below the ambient in order that only the ambient level be measured. If the difference
between the ambient and the noise source is 5 to 10 dB(A), then the level of the
Page 7 of 19 D:VminoiseelementW- 533- 4ccrp(.wpd12OFeb98 112:41 PM
O A) f
ambient itself can be reasonably determined by subtracting a one decibel correction
to account for the contribution of the source.
F. In the event the alleged offensive noise, as judged by the Director of Community
Development contains a steady, audible tone such as a whine, screech, or hum, or is
a repetitive noise such as hammering or riveting, or contains music or speech
conveying informational content, the standard limits set forth in Table I shall be
reduced by 5 dB(A).
G. Interior Noise Standards - General. The maximum interior sound levels noted below
shall apply to dwellings:
1. The interior noise standards as presented in Table 2 shall apply, unless
otherwise specifically indicated, within all dwellings units with windows in
their normal seasonal configuration.
Table 2
Interior Noise Limits
Type of Time Allowable Interior
Land Use Interval Noise Level dB(AJ
Single and Multi- family 10 p.m.- 7 a.m. 45
Residential 7 a.m. -.10 p.m. 45/55 (windows open)
2. No person shall operate or cause to be operated within a dwelling unit, any
source of sound or allow the creation of any noise which causes the noise
level when measured inside a neighboring receiving dwelling unit to exceed:
a. The noise standard as specified In Table 1 for a cumulative period of
more than five minutes in any hour; or
b. The noise standard plus 5 dB(A) for a cumulative period of more than
one minute in any hour; or c. the noise standard plus 10 dB(A) or the
maximum measured ambient, for any period of time.
H. If the measured ambient level differs from that permissible within any of the noise
limit categories above, the allowable noise exposure standard shall be adjusted in 5
dB(A) increments in each category as appropriate to reflect said ambient noise level.
Page 8 of 19 D :Uminoise e1ement117 -53 3- 4ccrpt.wpd11OFeb98 111:41 PM
I. Correction for character of sound. In the event the alleged offensive noise, as judged
by the Director of Community Development, contains a steady, audible tone such as
a whine, screech, or hum, or is a repetitive noise such as hammering or riveting, or
contains music or speech conveying informational content, the standard limits set
forth in Table 1 shall be reduced by 5 dB.
II. The factors which shall be considered in determining whether a violation of the provisions
of this section exists shall include, but not be limited to, the following:
A. The sound level of the objectionable noise.
B. The sound level of the ambient noise.
C. The proximity of the noise to residential sleeping facilities.
D. The nature and zoning of the area within which the noise emanates.
E. The number of persons affected by the noise source.
F. The time of day or night the noise occurs.
G. The duration of the noise and its tonal, informational or musical content.
H. Whether the noise is continuous, recurrent, or intermittent.
I. Whether the noise is produced by a commercial or non - commercial activity.
III. Noise Measurement procedure: Upon receipt of a complaint from a citizen, the Director of
Community Development or his /her designee, equipped with sound level measurement
equipment shall investigate the complaint. The investigation shall consist of a measurement
and the gathering of data to adequately define the noise problem and shall include the
following:

Page 9 of 19 D:Vminoiseelementl]7- 533- 4ccrpt.wpd12OFeb98 /12:41 PM
F. Utilizing the "A" Weighted scale of the sound level meter and the "slow" meter
response (use "fast" response for " impulsive sounds "), the noise level shall be
measured at a location or locations at any point on the receiver's property. The
microphone shall be located four to five feet above the ground and ten feet or more
from the nearest reflective surface, where possible. However, in those cases where
another elevation is deemed appropriate, the latter criteria shall be utilized. If the
noise complaint is related to interior noise levels, interior noise measurements shall
be made within the affected residential unit. The measurements shall be made at a
point at least four feet from the wall, ceiling, or floor nearest the noise source, with
windows in the normal seasonal configuration. Calibration of the measurement
equipment, utilizing an acoustic calibrator, shall be performed immediately prior to
recording any noise data.

City of Moorpark

The Noise Element is one of several mandated elements (sections)
required under State Law to be included in a communities General
Plan. The General Plan, a comprehensive evaluation and listing of
goals, policies and objectives - proides the visions of how the
community will grow and maintain its environmen& and setting.
The purpose of the Noise Element is to identify and evaluate noise
sources and problenmw in the community -as part of the information
base concerning decisions on the location and distribution of lard
uses. The identification of noise generators and the impact on the
community from fixed as well as mobile sources (automobiles,
trains) are important factors that influence the livability of the
community. Minimizing the noise impacts that result because of
growth in the community and the resulting human activity is an
important aspect of a complete Noise Element.
The current Noise Element was adopted in 1984F when the city of
Moorpark had a population of 17,561 persons. However, significant
growth has taken place since 1987 and updating thi.% document at
this time is appropriate. The current update uas first contracted
in 1994 with Mestre /Greve Consultants, but was delayed until 1996
when actual work on the technical /background report began.
This element update&, they nois& contours throughout the city and
establishes�� limitw or-, thresholds for. noise- generated from
statimexagaa=CO (locations) . As the city has increased in
population and other surrounding areas have grown, noise impacts
from transportation corridors in and through the city has
increased. bile:-traffic is the single highest generator of
noises ihf tFl Comity with projections along Los- Angeles Avenue,
State Routes( -I1W and 23 increasing by 5 decibels over 1994 levels
in the year 2010#.(General Plan Buildout). This is significant and
can be an impact, since any noise level increases over 3 decibles
is discernable by people.
Another major source of noise is the railroad with the line through
Moorpark which is a major link in the Southern California system.

These noise sources together with the increase in daily activity
because of population growth results in increased levels of ambient
(overall environment) noise in the community.
The Noise Element goals, policies and objectives are intended to
provide the necessary guidance for continued development of the
community and maintenance of the standards that are adopted to
limit the maximum acceptable level of noises. The adopted standards
will assist staff in the day to day decisions relating to land use
recommendations and establish criteria for the enforcement
The Technical Appendix which includes the detailed study results is
attached to the Noise Element and includes noise contour maps that
represent current noise levels (1994) as well as projected levels
for 2110. The map which illustrates existing noise contours shows
Los Angeles Avenue, Tierra Rejada Road and State Highways 23 and
118 as the most noise impacted vehicular corridors. The future
(projected) noise contour map indicates that these corridors will
have increased noise as noted earlier in this report, with added
occurring noted along a new proposed route for Highway 23. If
Highway 23 is relocated the result will be a noise level reduction
along Moorpark Avenue. However, as a general statement the noise
contours will spread out or widen around the corridors where
increased traffic flow occurs.
Submitted with the Noise Element is a proposed Noise Ordinance that
addresses enforcement-issues, particularly intrusive noise events
and noise generaftary in thee- community. The ordinance also
establishemIchresholdw that can be accurately measured to insure
the- -consi en an&�'defensible enforcement of code provisions
relatizW_Cd'=isft
The ordinance was prepared using the Statmt or California Model
Noise Ordinance and proposes the establishment of maximum
acceptable noise level standards by zoning district for day and
evening noise events*. The noise ordinance establishes noise levels
for residential, commercial and industrial uses, for vehicle noise
and stationary equipment`,: and identifies those uses which are
exempted from the standards,.

Concdusinn:
The adoption of the Noise Element will establish the goals,
policies and objectives concerning acceptable noise levels for the
community. The Noise Ordinance, if adopted, will assist in the
implementation of the element and provide the means for enforcement
of the standards determined to be appropriate for the city.
It is recommended that the Planning Commission adopt the attached
Resolution recommending to City Council that the projects are
categorically exempt from the California Environmental Quality Act,
approval of the updated Noise Element of the General Plan and
adoption of an ordinance adding Chapter 17.53 to the Municipal code
relating to Noise.
