Likewise, under the future (2025) with Haul Route 3 conditions,the northbound approaeh would be at LOS C,the seuthbound approach would be at LOS B and the other appfeaehes wettid remain a LOS A.

M:tigatiew No mitigation : required. 4.5 Noise The following mitigation measures have been revised. Mitigation Measures Measure 4.5.1a: At the start of stripping operations for each phase,the applicant shall construct an earthen berm along the portions of the project site that face sensitive receptors located within 2,000 feet of mining operations for that phase. This includes residences R4 and R5 northeast of Phase IV (this earthen berm would also attenuate noise to residences R5, R6,and R7)and residences RI, R2, and R3,west of Phase III and southwest of Phase V. The sound barriers must be at sufficient height(approximately 10 feet)to block the line of sight to the nearest sensitive receptor. If continuous earthen berms of adequate height are already in place,additional berms would not be needed. Mitigation Measure 4.5.1b: The Applicant shall conduct additional noise measurements after the completion of initial stripping activities to evaluate the effectiveness of Mitigation Measure 4.5.la in reducing resultant sound levels at outdoor activity areas of nearby sensitive receptors. For those residences existing as of project approval requiring additional — sound reduction,the Applicant shall fund the construction of solid (masonry or similar construction)walls along those property lines of the residences facing the project site,if desired and allowed by the subject property owners. Mitigation Measure 4.5.1c: For any residences existing as of project approval that would exceed a noise level of 45 dBA,Lps indoors,the applicant shall upgrade house noise — reduction via window and door upgrades on the side of the houses facing the mine, if the landowner desires and allows the work to be done. Measure 4.5.3: Depending on the selected Haul Route Option,the Applicant shall notify the homeowners (of residences existin asg�ofproiect approval) ((located along the roadway segments that would experience significant traffic-related noise)of the noise impacts associated with the traffic from project operations. At the request of homeowners along the affected segments (limited to a reasonable number of complaints as determined by the County and not to exceed once a year),the Applicant — Cemex Vernalis Quarry Mining arM Reclamation Project 442 ESA/203015 Final Ern,onrnental Impact Report June 2008
