mitigation measures of the proposed project in this EIR that would modify the design of any interstate freeways would require state and federal approval. Any changes to SR 132 would require state approval. Construction within a state right-of-way would require an encroachment permit. IMPACTS AND MITIGATION MEASURES Standards of Significance Project area roadways and intersections fall within the jurisdictions of San Joaquin County and Caltrans. Caltrans has established LOS D as the minimum acceptable LOS for traffic operations on project area roadways (Franzen, personal communication). The San Joaquin General Plan also requires LOS D be maintained at all intersections and State highway roadway segments. For-unsignalized intersections, LOS is measured for each approach that is stop sign controlled. Unsignalized intersections may operate at a lower LOS and still not satisfy traffic signal warrants. For unsignalized intersections, LOS E was considered the minimum acceptable LOS for individual traffic movements. The project would have a significant impact on traffic and circulation if it would: • Change the level of service at a signalized intersection, or on a State highway segment, from acceptable levels (LOS D or better) to unacceptable levels (LOS E or F). • Change the LOS for the stop sign controlled approaches to an unsignalized intersection from LOS E or better to LOS F. • add trips to an intersection or roadway which would operate at an unacceptable LOS without the project. • Cause failure of roadway structural sections or bridge structures. • Creation of an unsafe driving condition. Transportation and Circulation Impacts LOS summaries of existing and existing plus project conditions are provided in Tables 4.4-2 through 4.4-4. None of the alternatives would result in significant traffic LOS impacts if the proposed quarry opened today. However, there would be transportation and circulation impacts not identified by this LOS analysis, such as structural damage to the roadway sections and cumulative impacts. These effects are discussed below. It should be noted that the proponent has indicated that the processing plant will not receive or distribute truck traffic during the PM peak hour (4 to 6:30 PM). Therefore, an analyses of Ll this scenario was not conducted as part of this EIR and the proponent's permit application will be conditioned to restrict such activity.
