The 2000 Korve traffic study calculated the impacts of the traffic generated by the proposed ADT auto auction, plus other recently approved or planned industrial buildings in the business park, on nearby intersections and freeway segments("existing conditions plus project'). The study concluded that the traffic generated by the project would not impact any intersections. All nearby intersections would continue to operate at Level of Service (LOS) C or better, and all freeway segments would continue to experience LOS D or better. The analysis then examined impacts on intersections and roadways in the area assuming year 2020 cumulative development conditions, with and without the project. Cumulative 2020 conditions are based on the San Joaquin Council of Governments and City of Tracy transportation model and land use projections, which include substantial growth in the Tracy and Mountain House communities. Without the project,2020 cumulative growth would cause LOS F conditions at the I-205/Mountain House Parkway and I-580/Mountain House Parkway(Patterson Pass) freeway ramps. Addition of . a traffic light at each ramp, plus right turn lanes at two of the ramps would reduce the LOS F conditions to an acceptable LOS D or better. In addition, during cumulative year 2020 conditions, the project would add traffic to two nearby intersections(Berkeley Road and Schulte Road at Mountain House Parkway)which are forecasted to degrade the intersection level of service to LOS F. Project traffic would also affect operations along Schulte Road and Mountain House Parkway. The Korve report recommends that the ADT project applicant be responsible for contributing a fair share contribution to all of the identified improvements in the area that would be affected by project traffic. These fair share contributions would include the costs of installing a traffic signal at the Berkeley Road/Mountain House Parkway intersection;installing traffic signals and some right turn lanes at the I-205/Mountain House Parkway and I-580/Mountain House Parkway(Patterson Pass) freeway ramps; and improving the existing signal at Schulte Road/Mountain House Parkway. The Korve study also recommends that the ADT applicant contribute a fair share of costs to pay for widening Mountain House Parkway, constructing a new bridge over the Delta Mendota Canal,and widening Schulte Road. On-Site Circulation The 1994 Special Purpose Plan includes a conceptual on-site circulation plan for the Tri-State/Cheng parcel (the land north of the Special Purpose Plan boundary). The conceptual circulation pattern includes a long public-maintained loop road serving the northern portion of the business park property, with a series of cross-roads connecting the loop (Figure 8). The 1994 circulation plan a§sumed that the remaining portion of the Tri-State/Cheng parcel would be subdivided and developed in numerous industrial lots. With the proposed development of the ADT Auto Auction on 24-83 acres,the public loop road would not be required, since all circulation within the project site would be accomplished with private driveways and on private parking lots. To accommodate the auto auction site plan, the conceptual circulation plan would be modified to delete the public loop road system(Figure 8). 9323 1-BO.sppOO.wpd-7/27/00 —13—
