<br />, <br /> <br />I. PROJECT DESCRIPTION <br /> <br />. <br /> <br />A 76,000 square foot office park is proposed in Arden Hills, MN (see Figure 1). <br />The office park will be comprised of 30 "town-office" style units. The site is <br />currently occupied by the old city hall, which is vacant. It is assumed that the <br />development will be fully developed by 2006. The purpose of this report is to <br />determine if roadway or traffic control improvements need to be made to <br />accommodate the traffic generated by the development. <br /> <br />II. EXISTING CONDITIONS <br /> <br />Vehicles will have access to the development from existing driveways on <br />Highway 96 and County Road 50 (Ham line Avenue). The driveway on Highway <br />96 is a right-in/right-out access for the vacant city hall. The driveway on Hamline <br />Avenue is a full movement access for the daycare facility, which is aligned with <br />Karth Lake Circle. The driveways are shown on the proposed development plan, <br />which is included in the Appendix. <br /> <br />Highway 96 is a four lane, divided roadway with a 50 mph speed limit. It is a <br />county road. The office park's right-in/right-out access on Highway 96 will be <br />stop controlled. <br /> <br />. <br /> <br />Hamline Avenue transitions from a five lane roadway north of the site's driveway <br />to a three lane roadway south of the site. Hamline Avenue is County Road 50. It <br />has a 40 mph speed limit. The development's parking lot will connect to the <br />daycare's driveway, which is currently stop controlled. The existing lane <br />configurations and roadway network are shown in Figure 2. <br /> <br />The existing Highway 9610ld City Hall Driveway, Highway 96/Hamline Avenue, <br />and Hamline Avenue/Karth LakeCircle/Daycare Driveway intersections will be <br />critical in providing access to the development. TDI staff collected a.m. and p.m. <br />peak hour turning movement data at the two intersections on Hamline Avenue in <br />April 2005. The old city hall is not generating traffic because it is vacant. The <br />data is included in the Appendix. The existing a.m. peak hour traffic volumes are <br />shown in Figure 3 and the existing p.m. peak hour traffic volumes are shown in <br />Figure 4. Average daily traffic volumes for the area roadways are also shown on <br />Figures 3 and 4. These are 2002 volumes from Mn/DOT's traffic flow maps. <br /> <br />. <br /> <br />Arden Hills q{(tce Park <br />Tra.ffic Impact Study <br /> <br />Arden Hi1l5, M.N <br />A-iay 2005 <br />
