.. Traffic Impact Study March 24,2004 <br /> Proposed RMC Pacific Mining Site Page ES-3 <br /> r. <br /> EXECUTIVE SUMMARY (Continued) <br /> Intersection of Bird Road and Blewett Road <br /> The intersection of Bird Road and Blewett Road is currently operating at acceptable levels of <br /> ` service and is expected to continue to operate at acceptable levels of service through the year <br /> 2025 with construction of the project. <br /> Intersection of Koster Road and Blewett Road <br /> The intersection of Bird Road and Blewett Road is currently operating at acceptable levels of <br /> service and is expected to continue to operate at acceptable levels of service through the year <br /> 2025 with construction of the project. The intersection should be widened by expanding the <br /> existing pavement area to accommodate the proposed truck turning movements prior to operation <br /> of the project. <br /> Intersection of Welty Road and Blewett Road <br /> Project traffic is not expected at the intersection of Welty Road and Blewett Road. The <br /> intersection is currently operating at acceptable levels of service and is expected to continue to <br /> operate at acceptable levels of service through the year 2025 with construction of the project. <br /> Intersection of Bird Road and SR 132 <br /> The existing and cumulative conditions analyses indicate that the intersection of Bird Road and <br /> SR 132 is experiencing poor levels of service and requires improvements. Caltrans has approved <br /> a Project Study Report for an interchange to replace the existing intersection. The proposed <br /> interchange is expected to mitigate the cumulative and future impacts to the intersection. The <br /> project should be required to contribute an equitable share of the cost of the interchange. <br /> Intersection of Koster Road and SR 132 <br /> The intersection will operate at unacceptable levels of service based on cumulative-without- <br /> project conditions on the northbound and southbound approaches. The poor levels of service are <br /> primarily the result of the difficulty that would be experienced by vehicles attempting to turn left <br /> or proceed through across both directions of SR 132. The eastbound and westbound left-turn <br /> 6. lanes function at acceptable levels of service and are expected to continue to function at <br /> acceptable levels of service through the year 2025 with the project (both haul routes). <br /> 6. The future traffic volumes on Koster Road are expected to be minimal and it is not anticipated <br /> that traffic signal warrants will be met. Despite the poor levels of service for some movements, <br /> consideration of Haul Route 2 should not be precluded because project traffic would consist of <br /> eastbound right turns, northbound right turns, and westbound left turn movements. The analysis <br /> does not indicate that significant delays would be experienced by these turning movements <br /> which will operate at acceptable levels of service. <br /> The intersection is expected to be unsafe during foggy conditions, and it is not recommended that <br /> truck traffic utilize the intersection for fuming movements during foggy conditions. <br /> r <br /> L <br />
