In order to adequately determine the impacts, a Traffic Study is <br /> needed to address capacity and safety issues at all potential access locations to the State Highway <br /> System. This study should address existing plus project and cumulative conditions. <br /> - The traffic analysis needs to show current and projected daily traffic and am and pm peak <br /> hour conditions, directional split, peak hour turning movements and impacts of large trucks an the <br /> structural and operational aspects of 1-5, 1-580 and SR 132 Again,this information is also needed for <br /> cumulative conditions. <br /> J /- <br /> - A discussion which recommends mitigation measures for significant impacts and a reference to <br /> funding responsibTdy for any improvements made necessary by the project traffic and its share of <br /> cumulative traffic Improvement requirements. The mitigation's established for this project should be <br /> ' integrated with the mitigation and financial mechanisms established by the County of San Joaquin. <br /> - Due to on earlier study for the proposed Granite quarry on Gaffery Road it was determined that <br /> ?� the existing road and bridge system were not adequate to handle high volumes of truck traffic. The <br /> study identified a new 1-5 interchange south of Blewett with new county roads connections. from our <br /> inital review of this proposal, we believe that the moest efective mitigation for the truck traffic created <br /> k by this project would be to gain highway access from this proposed new interchange. We believe <br /> that this option needs to be fully investigated as part of the planning and environmental <br /> documentation for this project,including potential shared financial responsibilitles in order for the <br /> interchange to be Constructed. <br /> - It access along Koster Road to SR 132 is considered we believe that a new bridge over SR 132 <br /> will be required (consistent with the Freeway Agreement)with a right turn lane onto the frontage <br /> road, easterly to Highway 33 interchange providing freeway <br /> access. <br /> i <br /> f <br />
