Ms. McPherson Page Two January 22, 2004 results in additional delay being associated with the intersection of Jackson Street/Holt Street. Under year 2006 build conditions, all key intersections are expected to operate at an acceptable LOS D or better during the p.m. peak hours, with existing traffic controls, signal timing and geometric layout. Results of the year 2006 queuing analysis indicate that the eastbound left-turn movement at the intersection of TH 169/197t" Avenue may experience occasional queue length problems. The eastbound left-turn and through/right-turn queues at the intersection of TH 169/193rd Avenue will occasionally extend beyond the storage facilities into the adjacent Jackson Street/Holt Street intersection. However, this queuing does not significantly impact the overall operations at the adjacent intersection of Jackson Street/Holt Street. Although the results of the year 2006 p.m. peak hour build conditions show that all key intersections will operate at an acceptable overall LOS D or better, a sensitivity analysis was conducted at. the intersection of Jackson Street/Holt Street and TH 169/193rd Avenue. The analysis was conducted with an increase of 10 and 20- percent in traffic respectively. Under each situation the intersection of Jackson Street/Holt Street continued to operate with an acceptable overall LOS A/D. While all key intersections are expected to operate at acceptable levels of service, there are geometric improvements that can be implemented to proactively prepare for future conditions as well as improve safety. Figure 6 graphically displays the future year 2006 recommended intersection geometrics. These recommendations were formulated in coordination with Mn/DOT District 3 staff. Based on the analysis results, the proposed site plan layout and access recommendations are sufficient to service the proposed development in year 2006. The layout shown for the proposed Holt Street extension is appropriate for the current configuration of TH 169 and year 2006 forecast volumes. The recommended geometric improvements should be implemented with construction of the proposed Elk Ridge Center Development and realignment of 197the Avenue/ Irving Street. In addition, based on coordinating discussions with Mn/DOT and current plans to transition this area of TH 169 to a freeway facility over time, the proposed site plan layout will accommodate the future construction of a split-diamond interchange in the northwest quadrant of TH 169/197the Avenue. This particular interchange design does have some minor impacts to the proposed Elk Ridge Center development and site layout (block one, lot one). It is too early in the process to obtain any official comments from Mn/DOT staff. However, Mn/DOT felt that the developer has made a reasonable attempt to provide a workable solution. It should be noted that normal traffic analysis procedures would typically analyze a mid- week situation.
