Revised Traffic Impact Study March 27,2008 Proposed CEMEX Mining Site Page 19 To mitigate the impacts created by Haul Route 3 on opening day the Project may be conditioned to operate at a maximum annual production of 1.9 million tons while Haul Route 3 is in operation. If the Project is limited to 1.9 million tons per year, the near-term with Project level of service will be C and no significant impacts will occur. To mitigate significant impacts in the cumulative — conditions, the Project may be conditioned to eliminate Haul Route 3 after the pending construction of the Bird Road/SR 132 interchange, at which time only Haul Route 1 would be allowable. Interchange of Interstate 5 and State Route 132 The interchange is expected to operate at acceptable levels of service through the year 2025 with the Project based on the projected traffic volumes. The only exception is that the SR 132 westbound — merge from southbound I-5 may operate at a level of service D in the future with or without the proposed Project. This is not considered a Project-specific impact. Bird Road between Blewett Road and SR 132 Bird Road currently operates at acceptable levels of service and is expected to continue to operate at acceptable levels of service with the Project through the year 2025. _ SR 132 between Interstate 580 and McCracken Road The segments of SR 132 that consist of only one lane in each direction are currently operating at _ unacceptable levels of service. Where SR 132 is a four-lane divided highway, the road segment operates at acceptable levels of service. With construction of the Project, similar levels of service are expected to result. This indicates that SR 132 should be widened to include four lanes in each direction in the near future. The Project may be required to contribute an equitable share of the cost of the widening. With construction of two lanes in each direction and the eventual conversion to a freeway, SR 132 is expected to experience acceptable levels of service through the year 2025. _ Blewett Road between Bird Road and Welt Blewett Road currently operates at acceptable levels of service and is expected to continue to operate at acceptable levels of service with the Project through the year 2025. The Project and Haul Route 1 will create potential pavement impacts on Blewett Road between I-5 and Koster Road. The Project and Haul Route 3 will create potential pavement impacts on Blewett _ Road between Koster Road and Welty Road. However, it is noted that the TI analyses are based on a 20-year pavement design life. Therefore, if Haul Route 3 is considered only as a short-term option then an impact would not be identified. It is also noted that a pavement impact may not be identified _ if the traffic index used in design of the existing roadways is already capable of supporting the Project traffic volumes. Welty Road between Blewett Road and SR 132 Welty Road currently operates at acceptable levels of service and is expected to continue to operate at acceptable levels of service with the Project through the year 2025.
