SC -f o o� i will be noted. Identify improvements to each road that are already programmed and/or funded. Regulatory Framework Discuss federal, state, and local regulatory framework for transportation and I • circulation issues. Traffic policies and requirements, such as Caltrans management F plans and concept reports, General Plan traffic policies, and Caltrans and County traffic thresholds will be discussed as they relate to the project. Impact Analysis • Assign project trips to the study area street system under the "steady state" condition to determine if significant Level of Service impacts are anticipated on a daily or peak hour basis. Consider safety issues.associated with use of the study area roads by trucks and will evaluate the relative impact of truck traffic on.the structural section of study area roads. • KDA will quantify the number of trucks that will be used to haul materials over the life of the source and will use information.provided by the project proponents to Fil identify the rate at which materials will be shipped initially, as well as at expected at 'the "steady state" rate, seasonal variation will be addressed if applicable. While the plant may be capable of producing materials at a rate that exceeds the anticipated deliver schedule, we do not anticipate evaluating this "worst case" scenario. Information provided by the project proponents will be used to characterize the regional directional distribution of trucks to customers. Evaluation of truck impacts will include review, with County staff, of the approved operational agreements for other area plans in order to identify background truck volumes over the next twenty years. We will supplement this data as needed with P4, the current truck percentage and the cumulative background traffic volume to G estimate the total number of Equivalent Single Axle Loads (ESAL's) occurring over the next twenty years on master roads without the proposed project. We will also calculate the total ESAL's with the addition of project traffic. Resulting ESAL's will ; -_Fli be used to identify the Traffic Index (Ti) on each road. The general magnitude of truck impact will be described based on a potential impact to roads that are already Fin poor or fair conditions, as well as in terms of the relative change in TI on each road. • Provide Horizontal Geometric Assessment. We will use existing aerial photography h F or, if available, roadway improvement plans from San Joaquin County and Caltrans to assess if the roadways can accommodate the design vehicles as they make turns i! along the roadways leading to and leaving the project site. k # • Cumulative Impacts. We will work with San Joaquin County and Caltrans staff to identify applicable cumulative background traffic volumes on study area roads. We will identify cumulative Levels of Service with and without the proposed project. Mitigation Measures FNote safety or capacity improvements needed to address project or cumulative impacts. While we do not propose to describe the nature of the actual structural improvements needed on each road, we expect to note those locations where the F !
