Impact T-L• Increased Traffic at Roadways, Freeway Ramps, and Intersections Resulting from Project (Phase 1 Interchange) Conditions Under 2015 proposed project conditions with Phase 1 interchange improvements, traffic in the project area will increase. However, based on trip generation for assumed land uses and planned # intersection, interchange, and roadway improvements, roadways and intersections in the project area are expected to operate at LOS D or better. This impact is, therefore, considered less than significant. Although this impact is considered less than significant, the following mitigation measure is recommended to ensure that traffic operating conditions remain at LOS D or better as the project site is developed. Et ' Mitigation Measure T-1: Evaluate and Monitor Traffic Operating Conditions at Critical Roadways and Intersections and Implement Measures to Ensure that Operating Conditions iRemain at LOS D or Better Before each phase of development on the project site, the Department of Aviation in coordination with the Department of Public Works shall evaluate and monitor traffic operating conditions at the critical roadways and intersections identified in the traffic study. If is it determined that traffic operating conditions would not remain at LOS D or better with implementation of the planned development or if actual traffic operating conditions are not at LOS D or better, planned roadway and intersection improvement measurements shall be implemented before approval of ►� additional development on the project site to ensure that operating conditions remain at LOS D or better. Planned improvements include measures such as the addition of turning lanes at intersections and the addition of lanes to roadways. Before each phase of development on the project site, the County shall coordinate with the City of Stockton and Caltrans on the evaluation and monitoring 4 { of traffic operating conditions on critical roadways and interchanges. l .� 2015 PROPOSED PROJECT WITH PHASE 2 INTERCHANGE IMPROVEMENTS A summary of key data and assumptions for the proposed project with Phase 2 interchange E � improvements (i.e., with flyover ramps) at the Arch-Airport/SR 99 interchange is shown in Table 34. Planned roadway and intersection improvements assumed in the analysis are described in detail in the traffic study (KASL Consulting Engineers 1998). Intersection improvements " described above for Phase 1 interchange conditions (Table 7-4) apply to this condition with the exception that a single northbound right-turn lane would be needed at the intersection of Qantas and Arch-Airport Road instead of dual right-turn lanes. Roadway improvements are the same as those described above for Phase 1 conditions. , Stockton Metropolilan Airport Project Chapter T Transportation and Circulation Draft Environmental Impact Report March 20, 1998 7-8
