Debra Bloom, P.IJ. January 15, 2008 City of Roseville Page 17 Due to the physical constraints Haar the intersection of County Road C/Fairview Avenue (railroad line immediately south, high-voltage power line structures immediately south aril existing developments in the northwest and northeast quadrants), there are no minor improvements that can be implemented to obtain acceptable operations. Although only one intersection operates unacceptably, internal roadway configuration 2 includes an incomplete roadway system. Future plans for increased redevelapanent in this area (subarea I, II and III) dictate the need to establish a strong internal roadway network. Therefore, internal roadway configuration 3 was reviewed as the next recommended improvement. The analysis results shown in Table 6 indicate all key intersections will operate at an acceptable L4S D or better under year 2016 build conditions during the a.an. and p.m. peak hours, with internal roadway configuration 3 and the roadway ianprovemelrts listed at this point. In addition, the roundabouts along Twin Lakes Parkway will operate acceptably under this final year 2016 scenario.

Three distinct redevelopment scenarios were reviewed. The first represents the intent of the comprehensive plan and is inclusive of all major land use redevelopment options, based on a worst-case redevelopment scenario for traffic generation (Twin Lakes AUAR Update scenario A). The second redevelopment scenario is focused on residential development, combined with other complimentary land uses (i.e., offce grad retail} {Twin Lakes AUAR Update scenario B). The third redevelopment scenario represents anon-residential focus (Twin Lakes AUAR Update scenario C). The last rivo redevelopaxaent scenarios {B and C) were developed in an effort to balance land use size and trip generation. It should be noted that these scenarios have very similar total trips generated during floe p.3n. peak hour, while scenario B generates more trips on a daily basis.
