<br />" <br /> , . <br />I. PROJECT DESCRIPTION - <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 Ihis 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 />/I. EXISTING CONDITIONS <br /> Vehicles will have access to the development from existing driveways on <br /> Highway 96 and County Road 50 (Hamline 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 /> 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-infright-out access on Highway 96 will be <br /> stop controlled. ~ <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 /> The existing Highway 96fOld City Hall Driveway, Highway 96/Hamline Avenue, <br /> and Hamline Avenue/Karth LakeCirclefDaycare 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 MnfDOTs traffic flow maps. <br />~--~ ~ _m____ e <br />Arden Hitls Office Park I Arden iJiNs. MN <br /> Traffic lmpacl Stzui.Y May 2005 <br />
