INITIAL,STUDY/ENVIRONMENTAL DOCUMENTATION <br /> fULULYz000 STOCKTONMETROPOLrrANAIRPORT <br /> i <br /> SPECIAL PURPOSE PLAN <br /> F Ai ort Way/Dixon Road <br /> Add one through lane each at the northbound and southbound approaches. <br /> FRoute 9910antas Lane Flyover Ramns <br /> Construct flyover ramps from SR-99 into Airport East. <br /> FYear 2015(mitigation requirements are in addition to year 2010 mitigation): <br /> Complete the balance of the roadway improvements. <br /> All mitigation is based on additions and improvements to the Base 2015 No Project <br /> F condition lane geometry and intersection control. (See Traffic Impact Analysis, <br /> Appendix B, Figure 10). <br /> i . With mitigation,all of the impacted intersections' would operate at acceptable LOS <br /> "D"and a volume-to-capacity ratio of less than 1.0. (See Traffic Impact Analysis, <br /> Appendix B,Table 6). <br /> Airport Master Plan Mitigation: <br /> Mitigation Measure T-1: Evaluate and monitor traffic operating conditions at critical <br /> F roadways and intersections and implement measures to ensure that operating <br /> conditions remain at LOS "D"or better. <br /> C) Result in a change in air traffic patterns,including either an increase in traffic <br /> levels or a change in location that results in substantial safety risks? <br /> F <br /> Less than significant. The SPP will not cause an increase in air traffic conditions <br /> when compared with the assumptions included in the approved Master Plan. It is <br /> expected that non-commercial general aviation and military operations will occur as <br /> forecast in the approved Master Plan. Conversely,the number of commercial <br /> F operations is forecast to decline from the Master Plan assumption of 70 operations <br /> per day to 27 operations per day with the SPP. No other changes in air traffic <br /> conditions are planned. <br /> Fd) Substantially increase hazards due to a design feature (e.g F.,shat curves or <br /> dangerous intersections) or incompatible uses(e.g.,farm equipment)? <br /> F, <br /> Less than significant. The proposed road improvements will be designed to <br /> guidelines and standards included in the SPP with the objective of accommodating <br /> local vehicular traffic. <br /> t <br /> J e) Result in inadequate emergency access? <br /> Less than significant. With the proposed project,emergency access is provided <br /> around three sides of the SPP. Access to the SR-99 freewaywill be facilitated b <br /> Y <br /> widening of Arch-Airport Road and the implementation of the Arch Road/SR-99 <br /> interchange improvements. <br /> I Except for intersections at Arch-Sperry Road/French Camp Road and Airport Way/French Camp Road are <br /> mitigated to LOS F base conditions. <br /> 7/20100(P:1SJC0301Envirmunentai\initial studympd) <br /> 49 <br />
