Debra Bloom, P.E. City of .Roseville January l5, 2008 Page 22 Under year 2016 build conditions (internal roadway configuration 2}, all but one lcey intersection wilt operate at an acceptable overall LOS D or better during the a.m. and p.m. peak hours with internal roadway configuration 2 and its recommended roadway improvements. a The fallowing roadway improvements are necessary to achieve the level of service operations in the previous bullet: Cleveland Avenue at County Road D • Construct a northbound left-turn lane • Construct an eastbound left-tern lane • Operate intersection with north-south split-phasing Cleveland Avenue at County Rpad C2 s Install a traffic signal Cleveland Avenue at I-35W Northbound Ram s • 1/xtend the existing southbound left-turn lane Due to the physical constraints near the intersection of County Road ClFairview Avenue (railroad line immediately south, high-voltage power line structures immediately south and existing developments in the northwest and northeast quadrants}, there are no minor improvements that can implemented to obtain acceptable operations. Ahhnugh only one intersection operates unacceptably, internal roadway configuration 2 includes an incomplete roadway system. Future plans for increased redevelopment in this area (subarea I, II and III) dictate the need to establish a strong internal roadway network. • Under year 2016 build conditions (internal roadway configuration 3}, all key intersections will operate at an acceptable LOS D or better during the a.m. and p.m. peak hours with inten~al roadway configuration 3 and the roadway improvements Iisted at this point. In addition, the roundabouts along Twin Lakes Parkway will operate acceptably under this final year 2016 scenario. • For comparison purposes, we have reviewed the Twin Lakes AUAR Update scenario C versus the proposed and adjacent McGough development study assumptions (the comparison includes the entire Twin Lakes AUAR redevelopment area -subareas I, II and III). The Twin Lakes AUAR Update scenario C has the potential to generate 4,734 trips during the p.m. peak hour. A modif ed scenario C containing the land use assumptions presented in this current study will generate 5,194 trips during the p.m. peak hour (460 more p.m. peak hour trips}.
