INTRODUCTION <br />This report summarizes the results of a traffic analysis conducted for the proposed SuperTarget <br />redevelopment in Roseville, Minnesota. The new store will replace an existing Target facility in <br />the northeast quadrant of Snelling Avenue (TH 51) and County Road B(see site plan shown in <br />Figure I). In addition to the new SuperTarget, the proposed redevelopmentwill include two <br />small retail units, a sit-down restaurant and a fast food restaurant. <br />To improve traffic operations on County Road B, a median will be constructed between Snelling <br />Avenue and State Farm Road. The median will reduce traffic conflicts and delineate longer I,� <br />turn lanes. The roadway changes will focus existing traffic and added traffic demand that <br />crosses County Road B to the signalized intersection at State Farm Road. <br />The remainder of this report contains sections summarizing the: <br />• Existing Conditions <br />• Changes to Roadway Network <br />• Traffic Forecast Methodology and Assignment <br />• Traffic Analysis <br />• Potential Mitigations <br />• Conclusions <br />EXISTING CONDITIONS <br />To determine the traffic impacts caused by the planned development, it was first necessary to <br />documentthe existing conditions. For this task, aerial photographsof the site area were <br />assembled, reviewed and used as base maps. In addition, field visits were conducted to record <br />existing roadway geometry and to observe peak period traffic operations. As part of this field <br />site survey, intersection photos were taken to further document existing field conditions. <br />After this background information was gathered, a turn movement count data collection plan was <br />prepared and provided to the City for review. Based on the City review the plan was finalized, <br />resulting in peak period turn movement counts at 9 intersection locations (see Appendix Figure <br />A-1 for the count locations). On Tuesday, December 2,2003, the tum movement counts were <br />conducted for both the AM and PM peak periods for all of the locations identified in the data <br />collection plan. With counts done in early December in this commercial area, the traffic <br />volumes represent a conservative or "worst case" type of timefiame, as the data are from the <br />early holiday season, rather than the typical average daily volumes. <br />The AM and PM peak hour traffic demands were identified and summarized by intersection and <br />reviewed for quality assurance. One intersection with an apparent count anomaly was recounted. <br />With all of the data collected and checked, the single peak hour was extracted and summarized <br />from the peak period data collection efforts. The existing AM and PM peak hour turning <br />movement counts for the entire area are shown in Appendix Figure A-I. <br />Page 1 <br />
