4.Minor Revisions to the Draft Environments{Impact Report r Measure 4.4.1c: As a condition of approval,the applicant will be required to contribute an 6. equitable share of the cost of installing new traffic signals and construction of a separate southbound left-tum lane and protected left-turn phasing at the intersection of Bird Road and Blewett Road. Traffic signal warrants must be satisfied at this intersection for ►. implementation of this measure. These proposed improvements are expected to mitigate the cumulative impacts to the intersection (for Haul Route 1). Measure 4.4.1d: The proposed project will be conditioned to operate at a maximum annual production of 1.33 million tons while Haul Route 3 is in operation. If the proposed project is limited to 1.33 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 proposed project may be conditioned to eliminate Haul Route 3 after the construction of the Bird Road/SR 132 interchange, at which time only Haul Route Ir 1 would be allowable. Measure 4.4.1e: In order to address safety concerns associated with Haul Route 3 through the SR 33/Welty Road intersection,the proposed project will be required to implement the following improvements to this intersection to the extent feasible: • Construct 4-foot shoulders beyond the outermost truck wheel tracks. • Reconfigure intersection striping to prevent turning trucks from crossing over double yellow stripes. • Install signage to warn trucks about blocking,the railroad tracks. Consult with Union Pacific regarding any additional measures needed. • Reconfigure traffic stripes and trim or remove trees and vegetation to eliminate horizontal sight distance constraints. t` 0 Construct acceleration and deceleration lanes at the intersection for trucks turning right onto southbound Welty and northbound trucks turning left onto State Route 33. Impact Significance After Mitigation: Less than significant. Regional Roadway Operations Impact 4.4.2: The project would increase traffic on regional roadways in the project vicinity. This would be a potentially significant impact. ` A discussion of the project's potential impact to each roadway segment is provided below: L Cemex Vernalis Quarry Mining and Reclamawn Pmja4 4-37 ESA 203015 1" Final Emironrrenhl Impact Report June 2008
