Memo Project Name: Orono Apartments Traffic Review To: From: Bryant Ficek Re: Traffic Flow for the Orono Apartments Client: City of Orono File No: 139-98-000 Date: 11/07/00 ^ I Bonestroo Rosene Andedik& Associates 4 Architecti 0 The proposed Orono Apartments will be located in the northwest quadrant of the intersection of Trunk Highway (TH) 12 with Brown Road North in Orono, Minnesota. 1 To development currently exists on this site. The current site plan, dated October 17, 2000, shows two buildings. One building is proposed to be an apartment complex with 70 dwelling units and would be located on the east side of the site, next to Brown Road North. The other building is proposed to be an office building vvith approximately 23,200 square feet of area and would be located on the west side of the lot. Using the Institute of Transportation Engineers ’ trip generation rates for developments of this kind, the following table shows the estimated traffic volumes to and from the site. Time Period Office E In building Out Senior I In iousing Out Total Site In Trip Ends Out Average Weekday 130 130 120 120 250 250 AM Peak Hour 30 5 5 5 35 10 PM Peak Hour 5 30 5 5 15 35 Average Saturday 30 30 90 90 120 120 Average Sunday 10 10 95 95 105 105 As shown in the table, the site could expect about 250 vehicles in and 250 vehicles out of the site during a typical weekday according to the size and type of these developments. Site Access The current site plan shows the three access drives to and from the proposed development. The first access drive connects to Brown Road North on the east side of the lot. We would recommend aligning this site access drive, if possible, w'ith the access to the bank and private homes on the east side of Browm Road North, creating one four-legged intersection rather than two closely spaced ‘T’ intersections. One lane in each direction on the access drive should suffice for the expected amount of traffic. From this full access driveway, motorists could continue south to the existing full access intersection of Brown Road North with TH 12. Motorists should expect delays at this intersection of Brown Road North and TH 12 due to the traffic volumes on TH 12. We would not recommend a signal at this TH 12 intersection since other nearby intersections in both directions on TH 12 have existing signals. The current geometries at this TH 12 intersection are also adequate for the expected amount of traffic. Bonestroo, Rosene, Anderlik and Associates 2335 West Highway 36 + St. Paul.
