Construction Noise
Construction noise typically occurs intermittently and varies depending on the nature or phase of construction (e.g., land clearing, grading, excavation, paving). Noise generated by construction equipment, including earth movers, material handlers, and portable generators, can reach high levels.
During construction, exterior noise levels could affect the sensitive receptors near the construction site. Noise generated by construction equipment, including earth movers, material handlers, and portable generators, can reach high levels. Typical noise levels associated with individual construction equipment are listed in Table 5: Typical Construction Noise Levels.

kimley-horn.com 1100 W. Town and Country Road, Suite 700, Orange, CA 92868 714 939 1030 Following the methodology for quantitative construction noise assessments in the Federal Transit Administration’s (FTA’s) Transit Noise and Vibration Impact Assessment Manual (September 2018) (FTA Noise and Vibration Manual), the Federal Highway Administration (FHWA) Roadway Construction Noise Model (RCNM) was used to predict construction noise at the nearest sensitive receptors (i.e., the Residence Inn approximately 300 feet to the northwest and a single-family residence 320 feet southeast of the proposed expansion area). Table 6: Project Construction Noise Levels shows the estimated exterior construction noise levels at the nearest sensitive receptor.

Notes:
1. Per the methodology described in the FTA Noise and Vibration Manual (September 2018), distances are measured from the nearest receptor to the center of the project construction site.
2. The daytime construction noise standards of 80 dBA and 75 dBA are used for the nearest hotel and single-family residential uses, respectively, in accordance with MMC Section 16.30.130.

Construction activities would include site preparation, grading, paving, and architectural coating. Such activities may require graders, dozers, and tractors during site preparation; excavators, graders, dozers, tractors, and scrapers during grading; pavers, rollers, mixers, tractors, and paving equipment during paving; and air compressors during architectural coating. Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of full power operation followed by 3 to 4 minutes at lower power settings. Other primary sources of acoustical disturbance would be random incidents, which would last less than one minute (such as dropping large pieces of equipment or the hydraulic movement of machinery lifts).
kimley-horn.com 1100 W. Town and Country Road, Suite 700, Orange, CA 92868 714 939 1030 MMC Section 16.30.130 has established quantitative construction noise standards of 75 dBA for single-family residential uses, 80 dBA for multi-family residential uses, and 85 dBA for commercial/nonresidential uses during daytime hours (between 7:00 a.m. to 8:00 p.m.). As shown in Table 6, noise levels at the nearest sensitive receptors would range from 71.5 dBA to 72.1 dBA at the property line of the nearest sensitive receptors (the Residence Inn to the northwest and single-family residence to the southeast) during the site preparation phase. Therefore, construction noise levels would not exceed the City’s construction noise standards. While ambient noise levels in the Project vicinity would temporarily increase during construction activities, construction noise would be acoustically dispersed throughout the Project site and not concentrated in one area near surrounding sensitive uses. In addition, compliance with City of Murrieta Municipal Code Section 16.30.130 would further minimize impacts from construction noise, as construction would be limited to the hours of 7:00 a.m. to 8:00 p.m. daily except Sundays and holidays. Therefore, because project construction noise levels would not exceed MMC noise standards and construction activities would be required to comply with the City Code, noise impacts would be less than significant in this regard. Further, although construction noise levels may exceed the existing ambient levels in the area, construction would be temporary and would not result in a permanent increase in ambient noise levels in the area.
Operational Noise
The primary noise sources associated with the project’s expansion that could potentially impact nearby sensitive uses is a parking lot noise (i.e., car door slamming, car radios, engine start-up, and car pass-by) and off-site traffic noise. The proposed expansion would not change the existing truck delivery route and associated noise levels.
Parking Lot Noise. The project would provide new sales staging area including 610 parking stalls at the southwest portion of the existing CarMax facility. According to the project’s Traffic Memorandum prepared by Kimley-Horn (August 2023), the project would generate up to 24 trips during the peak hour. For the purpose of providing a conservative, quantitative estimate of the noise levels that would be generated from the vehicles entering and exiting the parking lot, the methodology recommended by FTA for the general assessment of stationary transit noise sources is used. Using the methodology, the project’s peak hourly noise level that would be generated by the on-site parking levels was estimated using the following FTA equation for a parking lot:
Leq(h) = SELref + 10 log (NA/1,000) – 35.6
Where:
Leq(h) = hourly Leq noise level at 50 feet
SELref = reference noise level for stationary noise source represented in sound exposure level (SEL) at 50 feet
kimley-horn.com 1100 W. Town and Country Road, Suite 700, Orange, CA 92868 714 939 1030 NA = number of automobiles per hour
35.6 is a constant in the formula, calculated as 10 times the logarithm of the number of seconds in an hour
Using the FTA’s reference noise level of 92 dBA SEL1 at 50 feet from the noise source, the project’s highest peak hour vehicle trips would generate noise levels of approximately 40.2 dBA Leq at 50 feet from the parking lot. The nearest sensitive receptor is located approximately 350 feet from the parking lot (new sales staging area). Conservatively assuming that all vehicles would park at a location nearest to sensitive receptors rather than dispersed throughout all available parking and based strictly on distance attenuation, parking lot noise at the nearest receptor would be 23.3 dBA, which is below the City’s 50 dBA and 45 dBA daytime and nighttime exterior noise standards, respectively, for residential properties.2 Parking lot noise currently occurs at the adjacent properties under existing conditions. Parking lot noise would be consistent with the existing noise in the vicinity and would be partially masked by background noise from traffic along area roadways. Noise associated with parking lot activities is not anticipated to exceed the City’s noise standards during operation. Therefore, noise impacts from parking lots would be less than significant.
Off-Site Traffic Noise. According to the project Traffic Memorandum, the project would result in a maximum of 287 vehicle trips to the project site and traffic would result in noise increases on project area roadways. In general, a traffic noise increase of 3 dBA is barely perceptible to people, while a 5- dBA increase is readily noticeable. Generally, traffic volumes on project area roadways would have to approximately double for the resulting traffic noise levels to increase by 3 dBA.3 According to the City of Murrieta General Plan Environmental Impact Report, Madison Avenue experiences approximately 3,400 average daily trips (ADT) between Murrieta Hot Springs Road and Guava Street.4 As such, project-generated traffic (287 daily trips) would not generate enough traffic to result in a permanent 3-dBA increase in ambient noise levels. Impacts would be less than significant in this regard.
1 Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, September 2018. 2 Multi-family residential noise standards have been assumed for hotel uses as a conservative measure. 3 According to the California Department of Transportation, Technical Noise Supplement to Traffic Noise Analysis Protocol (September 2013), it takes a doubling of traffic to create a noticeable (i.e., 3 dBA) noise increase. 4 City of Murrieta, General Plan Environmnetal Impact Report, Section 5.4 traffic and Circulation, Exhibit 5.4-5
kimley-horn.com 1100 W. Town and Country Road, Suite 700, Orange, CA 92868 714 939 1030 Vibration Impacts
Construction Vibration. Project construction can generate varying degrees of groundborne vibration, depending on the construction procedure and the construction equipment used. Operation of construction equipment generates vibrations that spread through the ground and diminish in amplitude with distance from the source. The effect on buildings located near the construction site often varies depending on soil type, ground strata, and construction characteristics of the receiver building(s). The results from vibration can range from no perceptible effects at the lowest vibration levels, to low rumbling sounds and perceptible vibration at moderate levels, to slight damage at the highest levels. Ground-borne vibrations from construction activities rarely reach levels that damage structures.
The Federal Transit Administration (FTA) has published standard vibration velocities for construction equipment operations. In general, the FTA architectural damage criterion for continuous vibrations (i.e., 0.20 inch/second) appears to be conservative. The types of construction vibration impact include human annoyance and building damage. Human annoyance occurs when construction vibration rises significantly above the threshold of human perception for extended periods. Building damage can be cosmetic or structural. Table 7: Typical Vibration Levels for Construction Equipment, lists vibration levels at 25 feet for typical construction equipment. Groundborne vibration generated by construction equipment spreads through the ground and diminishes in magnitude with increases in distance. As indicated in Table 7, based on FTA data, vibration velocities from typical heavy construction equipment operations that would be used during Project construction range from 0.003 to 0.210 in/sec PPV at 25 feet from the source of activity.
Table 7: Typical Vibration Levels for Construction Equipment Equipment Approximate Peak Particle Velocity
at 25 Feet (inches/second)
Approximate Peak Particle Velocity
at 75 Feet (inches/second)1
Vibratory compactor/roller 0.210 0.0404
Large bulldozer 0.089 0.0171
Loaded trucks 0.076 0.0146
Jackhammer 0.035 0.0067
Small bulldozer 0.003 0.0006
Notes:
1. Calculated using the following formula: PPV equip = PPVref x (25/D)1.5 where: PPV (equip) = the peak particle velocity in in/sec of the equipment adjusted for the distance PPV (ref) = the reference vibration level in in/sec from Table 7-4 of the FTA Transit Noise and Vibration Impact Assessment Manual, September 2018.
D = the distance from the equipment to the receiver
Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, September 2018. Table 7-4.
kimley-horn.com 1100 W. Town and Country Road, Suite 700, Orange, CA 92868 714 939 1030 The nearest structure to the construction activity is the commercial building located approximately 75 feet to the north of the proposed expansion construction activities. Vibration velocities from construction equipment would range from 0.0006 to 0.0404 in/sec PPV at the nearest structure, which would not exceed the structural damage criteria (0.2 in/sec PPV) or human annoyance criteria (0.4 in/sec PPV). It is also acknowledged that construction activities would occur throughout the Project site and would not be concentrated at the point closest to the nearest structure or sensitive receptor.
Therefore, vibration impacts associated with the proposed Project would be less than significant.
Operational Vibration. The project’s expansion proposes a new sales staging area which includes 610 parking spaces and would not change the truck delivery route or truck parking area. Therefore there would be no change to the existing truck-related vibrations occurring at the existing CarMax facility.
It should be noted that the existing CarMax facility truck movements are at low speed (not at freeway speeds) and would be over smooth surfaces (not under poor roadway conditions). Project-related vibration associated with truck activity would not result in excessive groundborne vibrations; no vehicle-generated vibration impacts would occur. In addition, there are no sources of substantial groundborne vibration associated with operation of the project, such as rail or subways. The project would not create or cause any vibration impacts due to operations and the impacts would be less than significant.
Conclusion
Project implementation would result in less than significant short- and long-term noise and vibration impacts. No mitigation measures would be required. Therefore, the proposed project would not result in significant effects related to Section 15332(d) of the State CEQA Guidelines.

MEMORANDUM
To: Jarrett Ramaiya, City Planner
City of Murrieta
From: Trevor Briggs, P.E.
Kimley-Horn and Associates, Inc.
Date: August 3, 2023
Subject: Traffic Memorandum for the Murrieta CarMax Expansion Project in the City of Murrieta
Kimley-Horn and Associates, Inc. has prepared a traffic memorandum for the proposed CarMax Expansion project in the City of Murrieta. The City has required submittal of this memorandum based on the City of Murrieta’s Traffic Impact Analysis Preparation Guidelines (March 2021).
PROJECT DESCRIPTION
The project site is located near the northeast corner of Madison Avenue and Guava Street in the City of Murrieta. The proposed project within its regional vicinity is shown on Figure 1. The project site is bounded by retail uses to the north, the Interstate 15 (I-15) freeway to the east, Guava Street and vacant land to the south, and Madison Avenue to the west. The applicant proposes to expand the existing 38.67-acre CarMax site to include the construction of 2 sales staging lots totaling 3.70 acres. The parcels for the two proposed staging lots are currently vacant. A copy of the project site plan is provided on Figure 2.
Vehicular access provisions for the project site would be provided via two full-movement, unsignalized driveways on Madison Avenue.
PROJECT TRIP GENERATION
The trip generation rates for the proposed project are based on trip generation rates used in the traffic study for the existing CarMax site (Traffic Impact Analysis (TIA) – CarMax Auto Superstore / Reconditioning Center #6002, Murrieta, CA; prepared by Hall + Foreman, Inc.; dated January 15, 2015). Relevant information pertaining to trip generation in the traffic study is included in Appendix A. The trip rates were derived from a trip generation study from other existing CarMax locations (Trip Generation Study – CarMax Auto Superstore / Reconditioning Center; prepared by Hall + Foreman, Inc.; dated October 2014; see Appendix B). Trip generation rates and the resulting trip estimates for the proposed expansion are summarized in Table 1. Consistent with the traffic study for the existing CarMax site, passenger car equivalent (PCE) factors were applied, with a 2.0 factor assigned to truck trips. Review of Table 1 indicates that the proposed expansion project is forecasted to generate 304 daily PCE trips, with 23 PCE trips (20 inbound and 3 outbound) during the morning peak hour and 25 PCE trips (9 inbound and 16 outbound) during the evening peak hour.

The City of Murrieta’s Traffic Impact Analysis Preparation Guidelines (March 2021) states that “the following activities generally will not require a TIA that includes LOS analysis… any use which can demonstrate trip generation of less than 100 vehicle trips in the peak hour.” Based on review of Table 1, the proposed expansion project would not generate 100 or more peak hour trips. Therefore, a LOS analysis is not required for the proposed project.
VEHICLE MILES TRAVELED (VMT) ASSESSMENT
Senate Bill 743 (SB 743) was approved by California legislature in September 2013. SB 743 requires changes to California Environmental Quality Act (CEQA), specifically directing the Governor’s Office of Planning and Research (OPR) to develop alternative metrics to the use of vehicular “Level of Service” (LOS) for evaluating transportation projects. OPR has prepared a technical advisory (“OPR Technical Advisory”) for evaluating transportation impacts in CEQA and has recommended that Vehicle Miles Traveled (VMT) replace LOS as the primary measure of transportation impacts. The Natural Resources Agency has adopted updates to CEQA Guidelines to incorporate SB 743 that requires VMT for the purposes of determining a significant transportation impact under CEQA.
The City of Murrieta’s Traffic Impact Analysis Preparation Guidelines (March 2021) provide details on appropriate screening thresholds that can be used to identify when a proposed land use project is anticipated to result in a less-than-significant impact without conducting a more detailed level analysis. Screening thresholds are broken down into the following criteria:
1. Project Type Screening
2. General Plan Comparison
Land development projects that meet one or more of the above screening thresholds may be presumed to create a less-than-significant impact on transportation and circulation.

The City presumes various usages, assumed to be local serving in nature, as having a less-thansignificant impact absent of substantial evidence to the contrary. The following uses are considered:
Projects generating less than 110 daily vehicle trips:
o 11 single family housing units
o 16 multi-family, condominiums, or townhouse housing units o 10,000 sf of office
o 15,000 sf of light industrial
o 63,000 sf of warehouse
Local-serving retail that primarily serves the City and/or adjacent cities Office and other employment-related land uses reducing commutes outside the local area Local-serving day care centers, pre-K, and K-12 schools Local parks and civic uses
Local-serving gas stations, banks, and hotels
Local-serving community colleges that are consistent with SCAG RTP/SCS assumptions Student housing projects
The proposed project includes the expansion of an existing CarMax site that provides a localserving used car dealership to serve the City of Murrieta and adjacent cities. Therefore, the project would satisfy the Project Type screening.
The Project Type threshold is met.
General Plan Comparison
In the City of Murrieta General Plan, the project site is zoned as Community Commercial. As noted previously, the project consists of the construction of two staging lots on 3.70 acres as an expansion of an existing local-serving used car dealership. The density of the proposed project is within the land use and zoning assumptions in the City’s General Plan and would not generate more VMT than what was analyzed in the General Plan. Based on the City’s Guidelines, the project’s VMT impact would be considered less than significant, and no further VMT analysis would be required.

FINDINGS AND CONCLUSIONS
Based on review of the City’s Traffic Impact Analysis Preparation Guidelines (March 2021), a LOS analysis is not required for the proposed project as the proposed expansion project would not generate more than 100 peak hour trips. Based on review of the City’s VMT screening thresholds, the proposed project would be considered local-serving and would be consistent with the assumptions in the City’s General Plan. Therefore, the proposed project would result in a lessthan-significant transportation impact and no additional VMT analysis is required.
