Rancho Santa Fe Road Project • Acoustical Assessment Report
City of Carlsbad
SUMMARY
Existing noise sensitive receivers in the project vicinity include four residences located along the
western portion of the project site along Rancho Santa Fe Road and approximately six residences
located at the intersection of Melrose Drive and Corintia Street. Future noise levels generated by
project traffic from the proposed road widening would exceed the Federal Highway Administration
and California Department of Transportation's noise criteria at the four homes located along Rancho
Santa Fe Road. A noise barrier constructed along the western right-of-way of Rancho Santa Fe Road,
south of Meadowlark Ranch Road, will be constructed by the City of Carlsbad as part of the proposed
project to reduce the noise impact at the single family residences. It is possible that the City of San
^ Marcos will construct this section of Rancho Santa Fe Road north of Melrose Drive. If the City of San
Marcos constructs this segment, the City of San Marcos would construct the noted noise barrier.
Noise impacts at the remaining existing residences within the project study area and adjacent land
uses would be less than significant. A single family development named the Meadowlands project
is currently under construction at the northwest intersection of Rancho Santa Fe Road and Melrose
Drive. As a condition of approvai for the Meadowlands project, noise barriers are to be constructed
by the developer at the homes adjacent to Rancho Santa Fe Road and Melrose Drive. The height and
locations of the noise barriers are based on an acoustical study prepared for that project.

^ 1.0 INTRODUCTION
m
• This noise study is provided for the proposed Rancho Santa Fe Road Bridge Repiacement project. The
proposed project is located within the City of Carlsbad and City of San Marcos. The City of Carlsbad
is the lead agency for the project. The project wouid also be federally funded, therefore, Caltrans is
a responsible agency.
m
m
This study documents the existing noise level based on noise measurement and modeling. The future
noise levels were calculated based on the proposed project's roadway design and traffic voiume
conditions. Noise sensitive receivers were identified and noise barriers have been evaluated where
necessary to achieve applicable noise criteria.
2 2.0 PROJECT DESCRIPTION
^ 2.1 Project Location and Setting
ta
PK The project site is located near the southeastern portion of the City of Carlsbad. The regional project
^ location is depicted in Figure 1 and the project vicinity is shown in Figure Z. The area of potential
effect associated with the project includes an approximate 450 linear foot distance along Rancho
I* Santa Fe Road immediately south of Meadowlark Ranch Road. The engineering design along this
ta 450-foot section of road was completed by the City of San Marcos as part of a separate road widening
project.
P
Adjacent to the project site are an industriai business park, undeveloped iand and approximately ten
m residences located within two residential areas. One residential area is located along the western
jl portion of the site near the intersection of Melrose Drive and Corintia Street. These residences are
located within the City of Carlsbad. The second residential area consists of four homes located on
• the west side of Rancho Santa Fe Road immediately south of Meadowlark Ranch Road. These homes
are located within the County of San Diego. An acoustical study was prepared evaluating noise
impacts along this section of road as part of the City of San Marcos' Rancho Santa Fe Road widening
J project (RECON 1998).
ta In addition, lots for single family residences for the Meadowlands project are currently being graded
in near the northwest intersection of Rancho Santa Fe Road and Melrose Drive. An acoustical study
has been previously prepared assessing noise impacts at these residences as part of the permit
J application for the development of the site (Segai 1985).

2.2 Project Characteristics
The City of Carlsbad's proposed Rancho Santa Fe Road improvement and bridge replacement project
would realign and widen approximately 3,500-linear feet of Rancho Santa Fe Road (S-10) from two
lanes to an ultimate six-lane Prime Arterial Roadway from just south of Ouesthaven Road to just
north of Melrose Drive in northern San Diego County,
p
ll Roadway Realignment
f* The proposed widening and realignment project is part of the City of Carisbad's General Plan to
upgrade Rancho Santa Fe Road to meet its designation as a Prime Arterial Roadway. A Prime Arterial
C Roadway has a 126-foot right-of-way containing six travel lanes, bike lanes, an 18-foot raised median,
sidewalks, curb, and gutter. The new bridge over San Marcos Creek is planned to accommodate the
Prime Arterial Roadway. The bridge replacement project would involve construction of a new bridge
^ in a location west of the existing bridge. The existing bridge will be demohshed.
The northerly roadway approach for the new bridge (s) will be approximately 2,200 feet long and
includes the reconstruction of the La Costa Meadows Drive/Rancho Santa Fe Road intersection, and
reconstruction of approximately 300 feet of La Costa Meadows Drive cast of the intersection. The
p, realigned Rancho Santa Fe Road will be constructed to the full width on the east side of the median,
with sidewalks, curb and gutter, and street lights from the bridge to north of Melrose Drive. The
west side of the roadway will be constructed with 32 feet of paving adjacent to the median curb.
The current alignment of Melrose Drive would be altered to accommodate the proposed widening
of Rancho Santa Fe Road. The Melrose Drive/Rancho Santa Fe Road intersection would be moved
approximately 400 feet to the north of the present intersection. Melrose Drive would be realigned
from the Corintia Drive/Melrose Drive intersection where Melrose Drive would extend to the
northwest to the realigned Melrose Drive/Rancho Santa Road intersection. Corintia Drive would be
Pl extended cast to connect with the realigned Melrose Drive. The potential exists that the City of San
Marcos may construct some improvements. However, for the purposes of the analysis conducted for
this report it is assumed that these roadway improvements would be constructed by the City of
Carlsbad.

3.0 NOISE CRITERIA
This report follows the noise criteria and policies established by the City of Carlsbad, County of San
Diego, as well as the California Department ofTransportation (Caltrans) and the Federal Highway
Administration (FHWA). These guidelines establish procedures for noise studies regarding traffic
noise prediction, noise analyses and noise abatement criteria.
HI The proposed project is located within portions of the City of Carlsbad, County of San Diego and
City of San Marcos. The City of Carlsbad and the County of San Diego noise criteria are applied
ffl within the applicable local jurisdiction area. Caltrans and FHWA noise criteria are also used for land
ill uses adjacent to Rancho Santa Fe Road and where Rancho Santa Fe Road is the predominant noise
source. There are no noise sensitive receivers aiong the project site that are located within the City
^' of San Marcos,
ffl
p» The City of Carlsbad describes community noise levels in terms of the Community Noise Equivalent
ff» Level (CNEL). The CNEL is a 24-hour average A-weighted sound level with a ten decibel (dB)
"penalty" added to noise during the hours of 10:00 p.m. to 7:00 a.m., and a five dB penalty added to
the evening hours of 7:00 p.m. to 10:00 p.m. The five and ten dB penalties are applied to account for
increased noise sensitivity during the evening and nighttime hours. The A-weighted scale measures
noise levels corresponding to the human hearing frequency response. All sound levels in this report
are A-weighted. Noise levels at residences immediateiy adjacent to Rancho Santa Fe Road were also
evaluated in terms of the peak hour average sound level. The peak hour average sound ievei is the
noise descriptor typically used by the FHWA and Caltrans when evaluating traffic noise.
3.1 City of Carlsbad Noise Criteria
The City of Carisbad requires that the maximum acceptable exterior noise level for new residential
development shail not exceed a CNEL of 60 dB.
3.2 County of San Diego Noise Criteria
The County of San Diego's maximum acceptable exterior noise level for new residential development
is that the CNEL shouid not exceed 60 dB. However, projects that are federally funded are to comply
with applicable FHWA standards.

The FHWA follows the noise abatement procedures established in the Code of Federal Regulations
(23 CFR 772). Caltrans also foiiows the noise abatement procedures as well as poiicies estabhshed
in Caltrans Highway Design Manual Chapter 1100.
The FHWA noise abatement criteria categorizes different activities and land uses for the purposes
of assessing noise impacts. Table 1 shows the FHWA noise abatement criteria. The criteria are based
on the peak hour (noisiest) average sound level which regularly occurs during a 24-hour period. The
noise abatement criteria for outdoor noise exposure typically is appiied where frequent human use
occurs such as swimming pools and common use areas at multi-family residences and the backyards
of single family homes.

The FHWA considers that a traffic noise impact occurs when the predicted traffic noise levels with
project approach within 1 dBA, or exceed the Noise Abatement Criteria. The FHWA specifies that
the Noise Abatement Criteria, when approached or exceeded, requires the consideration of traffic
noise abatement measures.

4.0 METHODOLOGIES AND INSTRUMENTATION
To determine the existing noise levels and potential noise impacts, a 24-hour and short-term noise
measurement were conducted adjacent to the project site. The 24-hour noise measurement was
made to determine the peak hour average noise level associated with traffic noise from Rancho Santa
Fe Road, and to determine the CNEL. Noise modeling was also conducted using CaItrans'SOUND32
traffic noise prediction model (Caltrans 1983). The SOUND32 noise model accepts as input the
number and types of vehicles on the roadway, vehicle speeds, and physical characteristics of the road
and topography; as well as receiver and noise barrier heights and locations. The CALVENO vehicie
noise emission levels were used in the noise model (Caltrans 1987).
The noise measurements were conducted using calibrated Larson-Davis Laboratories Model 700 (S.N.
1^ 2132) and Model 712 (S.N. 023 1) digital integrating sound level meters. The sound level meters
meet the current American Nationai Standards Institute standard for a Type 1 (Model 700) and Type
2 (Model 712) sound levei meters.
Traffic counts were made during the short-term noise measurement. The truck percentage used in
the noise model was 3.52% medium trucks and 1.24% heavy trucks for Rancho Santa Fe Road. The
truck percentage used for Melrose Drive was 1.83% medium trucks and 0.28% heavy trucks. The
truck percentages are based on vehicie mix surveys conducted by the City of Carlsbad (City of
Carlsbad 1995). To verify the input used in the noise model, the same traffic volume and vehicle
composition ratios counted during the noise measurements were used. The posted speed limit for
both Rancho Santa Fe Road and Melrose Drive is 45 miles per hour. This speed correlated weli with
the results of the noise measurement and were used in the noise modeling for these roads. The
modeled values were within 1 dB of the measured noise levels which confirms the assumptions used
in the noise model.
5.0 EXISTING CONDITIONS
Site A, as depicted on Figure 3, was monitored from 11:00 a.m. on Tuesday, July 15, 1997 to 11:00
a.m. on Wednesday, July 16, 1997. The primary noise source at the measurement site is traffic on
Rancho Santa Fe Road. Site A was selected to provide an unobstructed view of the Rancho Santa Fe
Road (i. e., no intervening walls, buildings, topography etc.). Tahle Z depicts the hourly average sound
levels during the measurement period at Site A. The peak (noisiest hour) average noise level was 70
p dB and occurred both during the morning commute and the evening commute hours.

A short-term noise measurement was also conducted at the residential area located at the northwest
intersection of Melrose Drive and Corintia Street (Site B, Figure 3). The traffic noise at these
residences is primarily associated with Melrose Drive, and to a lesser extent, Rancho Santa Fe Road.
The homes at this area have existing sound walls approximately 5 to 6-feet in height. The noise
measurement, conducted approximately 10 feet in front of the sound walls resulted in an average
sound level of 63 dB. The traffic noise level from Rancho Santa Fe Road was observed to typically
range from 52 to 58 dB at Site B. Tahle 3 depicts the results of the noise measurement adjacent to

The Meadowlands project is currently grading lots for singie family homes adjacent to the northwest
intersection of Rancho Santa Fe Road and Melrose Drive. An acoustical study prepared for that
project identified noise impacts exceeding the City's noise criteria for approximately 25 residential
lots located adjacent to Melrose Drive and Rancho Santa Fe Road (Segai 1985). Noise barriers were
recommended in the acoustical study to mitigate the noise impact to meet the City's applicable noise
criteria at the time the development permit application was approved (i.e., 65 dB l^J. This noise level
would comply with FHWA/Caltrans noise criteria. As part of the City's conditions of approval for
the Meadowlands project, the developer is required to construct the noise barriers at the residential
lots adjacent to Rancho Santa Fe Road and Melrose Drive.
6.0 FUTURE CONDITIONS
To determine future noise levels and the significance of potential noise impacts at land uses adjacent
to the project site, future year 2015 "built" and future year not built noise levels were calculated using

the SOUND32 model. The noise modeling included the future year 2015 traffic information and the
physical improvements shown on the preliminary designs for the road widening and intersection
improvements. The future year 2015 "not built" traffic volumes and existing roadway constituted
the "no build" scenario. The future year 2015 built scenario included the built traffic volumes as weli
as the proposed roadway improvements.
With implementation of the project, the future peak one-hour average noise level is projected to reach
approximately 71 dB at the backyards of the residences located along the west side Rancho Santa Fe
Road and south of Meadowlark Ranch Road (Sites 4, 5, and 6 on Figure 3). This noise level would
exceed Caitrans/FHWA noise abatement criteria. These are the only residences located adjacent to
Rancho Santa Fe Road that are within the project limits. Table 4 shows the existing, predicted future
"built" and future "not built" peak one-hour average noise levels at the receivers.

The future peak hour average noise level at the residences located along Melrose Drive would range
from approximately 60 to 64 dB. The future noise levels at these residences would be similar with
or without the project. This noise level would comply with the FHWA noise abatement criteria.
The peak hour average noise level at the homes located on the west side of Melrose Drive (Sites 1,
2 and 3 on Figure 3) would be approximately 60 to 64 dB associated with, traffic noise. This includes
the noise attenuation associated with the existing five to six-foot high sound wall at the residences.
The CNEL would be approximately one dB greater than the peak hour average noise level. The noise
level increase wouid primarily result from future traffic growth along Melrose Drive rather than noise
impacts associated with the project. As indicated in the preliminary design plans for the project,
Melrose Drive would be aligned farther away from the homes near the intersection of Melrose Drive
r and Corintia Street. The future noise level at the homes located near the intersection would be
approximately one dB lower with the project as compared to the not built scenario. The noise impact
associated with the project at these homes would be less than significant.
The business industrial park includes several outdoor lunch areas. Most of the lunch areas are located
along the east sides of the buildings which provide noise attenuation from the traffic noise.
However, a lunch area is located on the south side of the southern most building in the industrial
complex. The peak one-hour average noise level at this location would be approximately 66 dB. This
noise level complies with the FFIWA/Caltrans noise criteria.
A child care facility is located at the business industrial park along La Costa Meadows Drive east of
Rancho Santa Fe Road. The facility is partially shielded from traffic noise by intervening buildings.
The future peak hour average noise ievei at this location would be approximately 62 dB. This noise
level would comply with the FHWA/Caltrans noise criteria.
7.0 NOISE ABATEMENT MEASURES INCORPORATED INTO THE PROJECT
Future noise levels would exceed FHWA/Caltrans noise criteria at four homes located along Rancho
Santa Fe Road. Preliminary mitigation measures for the affected homes have been evaluated to
provide noise abatement and design information. With an eight-foot high sound wall located along
western right-of-way, the future peak hour average noise level would be mitigated to 61 to 62 dB.
The location of the proposed noise barrier is depicted on Figure 4- A comparison of the noise
reduction provided by various barrier heights is shown in Table 5. It should be noted that an eight-
foot high sound wall is depicted in the engineering design plans as part of the City of San Marcos'
Rancho Santa Fe Road widening project. The eight-foot wall height shown in the engineering design

plans is based on the acoustical assessment prepared for the City of San Marcos. Assuming the City
of San Marcos constructs this segment of Rancho Santa Fe Road, the City of San Marcos will
construct an eight-foot high sound wall at these residences. If the City of Carlsbad constructs the
proposed project first, the City of Carisbad has committed to constructing the noted sound wall
proposed by the City of San Marcos (City of Carisbad 1998).

Noise impacts associated with the proposed project would be less than significant at the existing
residences located aiong Melrose Drive, therefore, mitigation measures are not proposed by the City
at these residences.
8.0 CONSTRUCTION NOISE
Noise generated by construction equipment on this project would occur with varying intensities and
durations during the different phases of construction: clear and grub, earthwork, base preparation,
paving and cleanup.
Equipment expected to be used wouid include tractors, backhoes, pavers and other related
equipment. Maximum noise levels at 50 feet range from approximately 75 to 95 dB for the type of
equipment normally used in a project such as this.
