Conclusions Short Term This analysis has shown that possible site traffic generated by the proposed development will impact operations at mall entrance and adj acent street intersections. Five of the six intersections analyzed are expect to operate at LOS D or better under opening year 2006 build conditions for both the weekday P.M. peak and Saturday peak. The intersection of the Northeast mall entrance and County Road B-2 will need an additional eastbound left-turn lane under opening year 2006 build conditions to operate at the minimum acceptable LOS D. Long Term Future background traffic was determined using an estimated 20-year traffic growth factor of 1.5. This factor implies a 2% annual compounded growth rate. With this assumed background traffic growth it may be necessary for additional mitigation to maintain LOS D at all intersections. It should be understood that these long-term mitigation measures might not be needed if actual growth rates are less than the assumed rate. Under the 2025 build Saturday scenario long-term mitigation may include adding a Northbound right-turn lane at the North mall entrance. The intersection of Fairview Avenue and County Road B-2 would require mitigation under the 2025 \veekday P.M. scenario. The mitigation \Xfould include adding right-turn lanes on the Eastbound, Westbound, and Southbound approaches. Even under the 2025 No-Build scenarios the intersections of Fairview with County Road B-2 and the northeast mall entrance with County Road B-2 (and Snelling SB ramps) would both require mitigation to operate at the minimum acceptable LOS D. At a daily traffic level, The City of Roseville Comprehensive Plan Update 2003 lists 2000 Average Annual Daily Traffic (AADT) at 21,000 for County Road B-2 adjacent to Rosedale Mall. Using the 20-year 1.5 growth factor applied to the 2000 AADT of21,000 results in a 2020 AADT of31,500. The City ofRoseville Comprehensive Plan Update 2003 also contains a table of Daily Roadway Capacities. The table lists a LOS E capacity of 31,300 and a LOS D capacity of28,200 for a 4-lane divided roadway in a developed area. Using the assumed 20-year growth rate factor at a daily traffic level indicates a need for mitigation. The mitigation measures required could include some or all of those listed previously in the short term and long term under a no-build scenario. Figure 18 shows the 2000 AADT and projected 2020 AADT based on the 20 year 1.5 growth factor for county roads and 2000 AADT for Truck Highways. Potential queuing problems along with projected AADT traffic volumes appear to indicate SOlne short and long-term deficiencies with the current design of county road B-2 under peak traffic levels.
