GLOSSARY OF TERMS
Sound Pressure Level (SPL): a ratio of one sound pressure to a reference pressure (Lref) of
20 1-1Pa. Because of the dynamic range of the human ear, the ratio is calculated logarithmically
by 20 log {L/lref)
A-weighted Sound Pressure Level (dBA): Some frequencies of noise are more noticeable
than others. To compensate for this fact, different sound frequencies are weighted more.
Minimum Sound Level (Lmln): Minimum SPL or the lowest SPL measured over the time
interval using the A-weighted network and slow time weighting.
Maximum Sound Level (Lmax): Maximum SPL or the highest SPL measured over the time
interval the A-weighted network and slow time weighting.
Equivalent sound level (Leq): the true equivalent sound level measured over the run time.
Leq is the A-weighted steady sound level that contains the same total acoustical energy as the
actual fluctuating sound level.
Day Night Sound Level (LDN): Representing the Day/Night sound level, this measurement is
a 24 -hour average sound level where 10 dB is added to all the readings that occur between 10
pm and 7 am. This is primarily used in community noise regulations where there is a 10 dB
"Penalty" for night time noise. Typically LON's are measured using A weighting.
Community Noise Exposure Level (CNEL): The accumulated exposure to sound measured
in a 24-hour sampling interval and artificially boosted during certain hours. For CNEL, samples
taken between 7 pm and 10 pm are boosted by 5 dB; samples taken between 10 pm and 7 am
are boosted by 10 dB.
Octave Band: An octave band is defined as a frequency band whose upper band-edge
frequency is twice the lower band frequency.
Third-Octave Band: A third-octave band is defined as a frequency band whose upper band-
edge frequency is 1.26 times the lower band frequency.
Response Time (F,S,I): The response time is a standardized exponential time weighting of
the input signal according to fast (F), slow (S) or impulse (I) time response relationships. Time
response can be described with a time constant. The time constants for fast, slow and impulse
responses are 1.0 seconds, 0.125 seconds and 0.35 milliseconds, respectively.

EXECUTIVE SUMMARY
This noise study has been completed to determine the noise impacts associated with the
development of the proposed residential project. The project known as Miles Tentative Map
Residential Development consists of seventeen (17) new single-family units. The project site is
located west of Pio Pico Drive, north of Las Flores Drive, east and adjacent to Interstate 5 in the
City of carlsbad CA.
In order to meet the 60 dBA standard, the project would require a 14-foot high barrier placed
at the top of the proposed two foot berm along Interstate 5 for Lots 7-11 and a 6-foot barriers
around the perimeters of the remaining Lots. The City of carlsbad, as part of the Noise
Element, states that wall heights should not exceed six feet in height. Additionally, if the
acoustical study shows that exterior noise levels cannot be mitigated to the level allowable as
identified in this policy or less, the development should not be approved without one or more of
the following findings:
{1} Changes or alterations have been required in, or incorporated into, the project which avoid or
substantially lessen the significant environmental effect (noise).
(2) Changes or alterations to avoid or substantially lessen the significant environmental effect (noise) are
within the responsibility and jurisdiction of another public agency and not the City of carlsbad. Such
changes have been adopted by such other agency or can and should be adopted by such other agency.
(3) Specific economic, socia~ or other considerations make infeasible the mitigation measures or project
alternatives to avoid or substantially lessen the significant environmental effect (noise).
If a project is approved with exterior noise levels exceeding the level allowable pursuant to this
policy, all purchasers of the impacted property shall be notified in writing prior to purchase, and
by deed disclosure in writing, that the property they are purchasing is, or will be, noise
impacted and does not meet Carlsbad noise standards for residential property.
Based on the modeling results, with the incorporation of the 6-foot barriers the noise levels will
be between 59-67 dBA CNEL at the outdoor usable areas and would exceed the 60 dBA CNEL
threshold. Therefore, if the project is approved, proper notification in writing along with deed
disclosure must be given to all potential purchasers. All side yards should also have 6-foot
fencing to help with the noise reduction. Additionally, a final noise assessment is required prior to
the issuance of the first building permit for all Lots since the second level building facades are
above 60 dBA CNEL. This final report would identify the interior noise requirements based upon
architectural and building plans to meet the City's established interior noise limit of 45 dBA CNEL.
It should be noted; interior noise levels of 45 dBA CNEL can be obtained with a closed window
condition requiring a means of mechanical ventilation (e.g. air conditioning) for each building
and upgraded windows for all sensitive rooms (e.g. bedrooms and living spaces).

1.0 PROJECT INTRODUCDON
1.1 Purpose of this Study
The purpose of this Noise study is to determine potential onsite traffic noise impacts created
from nearby Interstate 5. Should impacts be determined, the intent of this study would be to
recommend suitable mitigation measures to bring those impacts to a level that would be
considered less then significant.
1. 2 Project Location
The proposed project is located within the City of Carlsbad, CA. More specifically, the project
site is located west of Pio Pico Drive, north of Las Flores Drive, east and adjacent to Interstate 5
in the City of Carlsbad CA. Access to the project site is from Pio Pico Drive via Las Flores Drive.
A general project vicinity map is shown in Figure 1-A on the following page.
1.3 Project Setting
The proposed project consists of 17 single-family residences. The existing site conditions are
characterized as disturbed land that is currently utilized as a nursery. Residential uses exist
adjacent to the site to the north, south and east. Interstate 5 is located along the western
boundary of the site. A project site plan is shown in Figure 1-B on Page 3 of this report.

2.0 ACOUSTICAL FUNDAMENTALS
Noise is defined as unwanted or annoying sound which interferes with or disrupts normal
activities. Exposure to high noise levels has been demonstrated to cause hearing loss. The
individual human response to environmental noise is based on the sensitivity of that individual,
the type of noise that occurs and when the noise occurs. Sound is measured on a logarithmic
scale consisting of sound pressure levels known as a decibel (dB). The sounds heard by
humans typically do not consist of a single frequency but of a broadband of frequencies having
different sound pressure levels. The method for evaluating all the frequencies of the sound is to
apply an A-weighting to reflect how the human ear responds to the different sound levels at
different frequencies. The A-weighted sound level adequately describes the instantaneous noise
whereas the equivalent sound level depicted as Leq represents a steady sound level containing
the same total acoustical energy as the actual fluctuating sound level over a given time interval.
The Community Noise Equivalent Level (CNEL) is the 24 hour A-weighted average for sound,
with corrections for evening and nighttime hours. The corrections require an addition of 5
decibels to sound levels in the evening hours between 7 p.m. and 10 p.m. and an addition of 10
decibels to sound levels at nighttime hours between 10 p.m. and 7 a.m. These additions are
made to account for the increased sensitivity during the evening and nighttime hours when
sound appears louder.
A vehicles noise level is from a combination of the noise produced by the engine, exhaust and
tires. The cumulative traffic noise levels along a roadway segment are based on three primary
factors: the amount of traffic, travel speed, and the vehicle mix ratio or number of medium and
heavy trucks. The intensity of traffic noise is increased by higher traffic volumes, greater speeds
and increased number of trucks.
Because mobile/traffic noise levels are calculated on a logarithmic scale, a doubling of the traffic
noise or acoustical energy results in a noise level increase of 3 dBA. Therefore the doubling of
the traffic volume, without changing the vehicle speeds or mix ratio, results in a noise increase
of 3 dBA. Mobile noise levels radiant in an almost oblique fashion from the source and drop off
at a rate of 3 dBA for each doubling of distance under hard site conditions and at a rate of 4.5
dBA for soft site conditions. Hard site conditions consist of concrete, asphalt and hard pack dirt
while soft site conditions exist in areas having grade changes, landscaped areas and vegetation.
On the other hand, fixed sources radiate outward uniformly as it travels away from the source.
Their sound levels attenuate or drop off at a rate of 6 dBA for each doubling of distance.
The most effective noise reduction methods consist of controlling the noise at the source,
blocking the noise transmission with barriers or relocating the receiver. Any or all of these
methods may be required to reduce noise levels to an acceptable level.

3.0 SIGNIFICANCE THRESHOLDS AND STANDARDS
The City of carlsbad's Noise Guidelines Manual {1995) requires that all exterior sensitive areas
shall limit noise exposure. For noise sensitive residential land uses, the City has adopted a
policy which has established a "normally acceptable" exterior noise level goal of 60 dBA CNEL
for the outdoor areas and an interior noise level of less than 45 dBA CNEL. For residential
properties identified as requiring a noise study, the study shall document the projected
maximum exterior noise level and mitigate the projected exterior noise level to a maximum
allowable noise level as identified in the Noise Guideline Manual. If the acoustical study shows
that exterior noise levels cannot be mitigated to the level allowable as identified in this policy or
less, the development should not be approved without one or more of the following findings:
{1} Changes or alterations have been required in, or incorporated into, the project which avoid
or substantially lessen the significant environmental effect (noise).
(2) Changes or alterations to avoid or substantially lessen the significant environmental effect
(noise) are within the responsibility and jurisdiction of another public agency and not the City of
carlsbad. Such changes have been adopted by such other agency or can and should be
adopted by such other agency.
(3) Specific economic, socia~ or other considerations make infeasible the mitigation measures
or project alternatives to avoid or substantially lessen the significant environmental effect
(noise).
If a project is approved with exterior noise levels exceeding the level allowable pursuant to this
policy, all purchasers of the impacted property shall be notified in writing prior to purchase, and
by deed disclosure in writing, that the property they are purchasing is, or will be, noise
impacted and does not meet carlsbad noise standards for residential property.
california Noise Insulation Standards (california Code of Regulations, Title 24) and the City of
carlsbad Noise Element establish an interior noise standard of 45 dBA for residential structures.
Acoustical studies must be prepared for residential structures that are proposed to be located
within the Community Noise Equivalent Level (CNEL) noise contours of 60 dBA or greater. In
addition, the City requires residential structures located within the CNEL noise contours of 60 or
greater to prepare an acoustical study. The studies must demonstrate that the building is
designed to reduce interior noise to 45 dBA or lower (CNEL).

4.0 NOISE ENVIRONMENT
4.1 Existing Noise Environment Onsite
Noise measurements were taken using a Larson-Davis Model LxT Type 1 precision sound level
meter, programmed, in "slow" mode, to record noise levels in "A" weighted form. The sound
level meter and microphone were mounted on a tripod, five feet above the ground and
equipped with a windscreen during all measurements. The sound level meter was calibrated
before and after the monitoring using a Larson-Davis calibrator, Model CAL 200.
Monitoring location 1 (ML1) was located in the future location of Lot 1; monitoring location 2
(ML2) was located near the future location of Lots 8 and9. The results of the noise level
measurements are presented in Table 4-1.
The noise measurements were monitored for a time period of 30 minutes during heavy traffic
conditions. The existing noise levels in the project area consisted primarily of traffic from
Interstate 5. The ambient Leq noise levels measured in the area of the Project during the
afternoon hours were found to be roughly 57-73 dBA. The statistical indicators Lmax, Lmin,
LlO, L50 and L90, are given for the monitoring location. As can be seen from the L90 data,
90% of the time the noise level is approximately 51-71 dBA from Interstate 5. The lower noise
levels in the northern portion of the site are due to distance separation and the vertical off set
between Interstate 5 and the Project site (the roadway is located 20 feet or more below the
site). The noise monitoring locations are provided graphically in Figure 4-A on the following
page.

4.2 Future Noise Prediction Methodology
The required coordinate information necessary for the Sound32 traffic noise prediction model input
was taken from the preliminary site plans provided by BHA, Inc., October 2012. To determine the
future noise levels the preliminary site plans were used to identify the pad elevations, the roadway
elevations, and the relationship between the noise source(s) and the receptor areas. To evaluate
the future potential noise impacts on the proposed development, outdoor observers were located
in the private areas of each Lot. The first floor modeled observers were placed five feet above
the finished pad elevation. In addition, the top of pads along with the proposed two foot berms
along Lots 7-11 were modeled to adjust for grade separation and the natural shielding from the
roadways.
To determine the future noise environment and impact potentials the Sound32 model was
utilized. The critical model input parameters, which determine the projected vehicular traffic noise
levels, include vehicle travel speeds, the percentages of automobiles, medium trucks and heavy
trucks in the roadway volume, the site conditions and the peak hour traffic volume. The peak hour
traffic volumes range between 6-12% of the average daily traffic (ADT) and 10% is generally
acceptable for noise modeling.
Table 4-2 presents the roadway parameters used in the analysis including the peak traffic
volumes, vehicle speeds and the hourly traffic flow distribution (vehicle mix). The vehicle mix
provides the hourly distribution percentages of automobile, medium trucks and heavy trucks for
input into the Sound32 Model. The Buildout conditions include the future traffic volume forecasts
provided in the Caltrans Noise Study Report for I -5 North Coast Corridor Widening Project. The
traffic was broken into lane segments for the main lanes and HOV lanes base on the ultimate
Buildout configuration. The modeled observer locations for each Lot are presented in Figure 4-B
on the following page.

5.0 FINDINGS AND MmGAllON
The Buildout analysis was modeled utilizing the roadway parameters described above in Section
4 and shown in Table 4-2 for the future conditions. In order to meet the 60 dBA standard, the
project would require a 14-foot high barrier placed at the top of the proposed two foot berm
along Interstate 5 for Lots 7-11 and a 6-foot barriers around the perimeters of the remaining
Lots. The City of carlsbad, as part of the Noise Element, states that wall heights should not
exceed six feet in height. Additionally, if the acoustical study shows that exterior noise levels
cannot be mitigated to the level allowable as identified in this policy or less, the development
should not be approved without one or more of the following findings:
{1} Changes or alterations have been required in, or incorporated into, the project which avoid or
substantially lessen the significant environmental effect (noise).
(2) Changes or alterations to avoid or substantially lessen the significant environmental effect (noise) are
within the responsibility and jurisdiction of another public agency and not the City of carlsbad. Such
changes have been adopted by such other agency or can and should be adopted by such other agency.
(3) Specific economic, social, or other considerations make infeasible the mitigation measures or project
alternatives to avoid or substantially lessen the significant environmental effect (noise).
If a project is approved with exterior noise levels exceeding the level allowable pursuant to this
policy, all purchasers of the impacted property shall be notified in writing prior to purchase, and
by deed disclosure in writing, that the property they are purchasing is, or will be, noise
impacted and does not meet carlsbad noise standards for residential property.
The modeling results for a six foot wall, in combination with a two foot berm for Lots 7-11, are
quantitatively shown in Table 5-1 below. As can be seen in Table 5-1, with the incorporation of
the 6-foot barriers the noise levels will be between 59-67 dBA CNEL at the outdoor usable areas
and would exceed the 60 dBA CNEL threshold. Therefore, if the project is approved, proper
notification in writing along with deed disclosure must be given to all potential purchasers.
Figure 5-A on the following page shows the location of the barriers to reduce the noise levels at
the proposed exterior outdoor areas. All side yards should also have 6-foot fencing to help with
the noise reduction. The barriers must be constructed of a non-gapping material consisting of
masonry, V2 inch thick glass, earthen berm or any combination of these materials. The 532
models input parameters and output files for the future conditions with and without the
mitigation are also provided in Attachment A.

Additionally, a final noise assessment is required prior to the issuance of the first building permit
for all Lots since the first and second level building facades are above 60 dBA CNEL. This final
report would identify the interior noise requirements based upon architectural and building plans to
meet the City's established interior noise limit of 45 dBA CNEL. It should be noted; interior
noise levels of 45 dBA CNEL can be obtained with conventional building construction methods
and providing a closed window condition requiring a means of mechanical ventilation (e.g. air
conditioning) for each building and upgraded windows for all sensitive rooms (e.g. bedrooms
and living spaces).
