5.Mitigation Monitoring and Reporting Program TABLE 5-1 MITIGATION MONITORING AND REPORTING PROGRAM CEMEX VERNALIS QUARRY PROJECT Mitigation Measure Responsible Party Monitor Timing Sign Off 4.4 TRANSPORTATION AND CIRCULATION 4.4.1a: Although the intersection of Koster and Blewett Roads is anticipated to operate at Applicant Pfd Prior to Issuance of acceptable levels of service with project implementation,the intersection will require widening to Grading or Building accommodate truck turning movements if access to the mining site is provided via Koster Road Permits (South Costa Ranch Road).Additionally,all-way stop control will be required to mitigate this intersection's cumulative year 2025 unacceptable levels of service impacts from Haul Route 1. If the County allows the use of this site access,the project sponsor would fund its fair share of this measure as a condition of approval of the project.Peters Engineering Group conducted a Fair-Share Percentage analysis as part of its Traffic Impact Study for this project. 4.4.1 b:As a condition of approval,the applicant will be required to contribute an equitable share of Ongoing the cost of the construction of a new Interchange at SR 132 and Bird Road. Applicant's payment of its equitable share will be made through the creation of a CFD according to the County's June 6, 2008 Acceptance of Petition from the Vernalis Producers Group to Form a Community Facilities District,or other similar financing mechanism. Caltrans has approved a Project Study Report for an interchange to replace the existing Intersection. The proposed interchange is expected to mitigate the cumulative impacts to the intersection(for Haul Route 1). 4.4.1c:As a condition of approval,the applicant will be required to contribute an equitable share of the cost of installing new traffic signals and construction of a separate southbound left-tum lane and protected left-tum phasing at the intersection of Bird Road and Blewett Road.Traffic signal warrants Once warrants met 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). 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 Until Bird/132 mitigate significant impacts in the cumulative conditions,the proposed project may be conditioned to interchange built eliminate Haul Route 3 after the construction of the Bird Road/SR 132 interchange,at which time only Haul Route 1 would be allowable. 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 Cemex Vernalis Quarry Mining and Recantation Project 5-3 ESA/203015 Final En*wirrertlsl Impact Report June 200
