Koster Road shall have one through lane and <br /> one right-tum lane in the northbound_direction south of the intersection. The <br /> 1- < improvement plans and specifications shall be prepared by a registered civil <br /> engineer and shall be subject to approval by the San Joaquin County Department <br /> of Public Works and by Caltrans. <br /> Level of Significance After Mitigation.- <br /> Implementation <br /> itigation:Im lementation of Mitigation Measure 4.4-3a would reduce Alternatives I and 2s <br /> effect on intersection LOS to a less-than-significant level <br /> Mitigation Measure 4.4-3b (Alternative 3) <br /> 1 , <br /> A traffic signal shall be included in the design of the Vernalis interchange at the i <br /> intersection of the southbound 1-5 ramps with relocated Bird Road.
