JOB NO: 16570-04 Noise Eval
SUBJECT: MURRIETA AND ETHANAC NOISE ASSESSMENT
Urban Crossroads, Inc. has completed the following Noise Assessment for the Murrieta and Ethanac (Project), which is located at east of Geary Street, south of Ethanac Road and west of Murrieta Road in the City of Menifee. The proposed Project is to consist of an approximately 517,720 square foot (SF) industrial warehouse building.

PROJECT OVERVIEW
On November 20, 2024, Urban Crossroads, Inc. prepared the Noise and Vibration Analysis (NA) for the Project. (1) The Noise Analysis evaluated the existing noise conditions, the off -site traffic noise levels as well as the Project construction and operational noise and vibration impacts. The NA determined that three segments near the Project site will experience Potentially Significant Project- related traffic noise increases. The purpose of this work effort is to explore why this Project triggers significant impacts when the off-site traffic noise impacts for other recently approved Projects were less than significant. For this evaluation, we reviewed the following recently approved noise studies completed by Kimley Horn and Associates, Inc.
• Northern Gateway Logistics Center Acoustical Assessment, April 2024. • CADO Menifee Industrial Warehouse Project Acoustical Assessment, March 2024

SUMMARY OF FINDINGS
The analysis shows that using the same assumptions as the Kimley Horn Acoustical Assessments, the Murrieta and Ethanac off-site traffic noise impacts would be considered less than significant for the study area roadway segments

16570-05 Noise Eval 2 Murrieta and Ethanac

OFF-SITE TRAFFIC NOISE ANALYSIS
Noise level increases resulting from the Project are evaluated based on the Appendix G CEQA Guidelines. Under CEQA, consideration must be given to the magnitude of the increase, the existing baseline ambient noise levels, and the location of noise -sensitive receivers to determine if a noise increase represents a significant adverse environmental impact. Based on the FICON significance criteria for off -site traffic noise presented in Table 4 -1 of the NA , three of the study area roadway segments are shown to experience potentially significant off -site traffic noise increases due to the proposed Project traffic conditions. The segments are described below. • Geary Street south of Ethanac Road (Segment #1)
• Murrieta Road south of Ethanac Road (Segment #3)
• Ethanac Road east of Murrieta Road (Segment #8)
Table 1 presents a summary of the existing conditions incremental noise increases by roadway segment outlined in the NA.

Noise sensitive uses limited to existing residential land uses. 2 The CNEL is calculated at the boundary of the right-of-way of each roadway and the property line of the receiving land use. 3 Does the Project create an incremental noise level increase exceeding the significance criteria (Table 4-1)? Table 1 shows that Geary Street south of Ethanac Road (Segment #1) will experience noise level increases of up to 17.6 dBA. However, a review of the existing conditions show that this roadway segment is currently an unpaved dirt road that passes three existing homes located on Floyd Avenue.

With little to no existing traffic on Geary Street, the off-site traffic noise levels on Geary Street south of Ethanac Road were calculated at 48.3 dBA CNEL. The addition of the Project traffic including medium and heavy trucks shows that the off-site traffic noise levels at the right-of-way are estimated at 65.9 dBA CNEL.

16570-05 Noise Eval 3 Murrieta and Ethanac
Based on the FICON significance criteria, this impact or perceived increase in noise levels for the homes adjacent to Geary Street south of Ethanac Road (Segment #1) is considered potentially significant. In addition, the NA fully accounts for the Project related truck trips recognizing that the trucks disproportionately influence traffic noise due to their size, weight, engine characteristics, and tire-road interactions, which generate significantly higher noise levels compared to lighter vehicles like passenger cars.

ACOUSTICAL ASSESSMENT OFF-SITE TRAFFIC NOISE ANALYSIS
A review of the recently approved Kimley Horn and Associates, Inc., Acoustical Assessments (AA) (2) shows that the off-site traffic noise analysis assumptions differ substantially from those used in the NA. Both studies rely on the Federal Highway Administration (FHWA) Traffic Noise Prediction Model- FHWA-RD-77-108 (19) with adjustments for the California Vehicle Noise (Calveno) Emission Levels (21). However, a comparison of the AA and the NA shows the following key differences.

1. The AA does not evaluate the existing without project conditions. On page 18 of the CADO Acoustical Assessment, the dirt roads are not analyzed and are simply labeled as “N/A”.

2. All off-site traffic noise levels in the AA are measured at a uniform distance of 100 feet from the centerline. The NA evaluates the traffic noise levels at the edge of the right -of-way of the adjacent land use. For Geary Street south of Ethanac Road (Segment #1), this places the receiver at 37 feet from the centerline, substantially closer than the AA.

3. The AA does not account for the heavy truck component of the Project. The NA recognizes that the addition of the Project related truck trips increases the percentage of heavy trucks in the vehicle mix.

4. The AA suggests that vehicles traveling on unpaved and gravel roads are 4-dBA louder than vehicles on paved roads.

Table 2 presents a summary of the off -site traffic noise levels using the same assumptions outlined in the AA. Using the AA assumptions, the calculations included in Appendix 1 show that the Project related off-site traffic noise increases will range from 0.0 to 6.7 dBA CNEL. Only Geary Street south of Ethanac Road (Segment #1) is shown to experience potentially significant off-site traffic noise impacts using the AA methodology. However, if we include the 4 dBA reduction to reflect the paved road consistent with AA, the Project noise increase is reduced to 2.7 dBA CNEL. The analysis shows that using the same approved off-site traffic methodology from AA, the Project impacts would be considered less than significant on all the study area roadway segments.
