- S• COSI I TING ENGINEERS May 19, 1994 File: 230-221-11 Mr. Steve Ach City Planner City of Elk River 13065 Orono Parkway CIVIL ENGINEERING Elk River, MN 55330 ENVIRONMENTAL RE: DARKENWALD PROPERTY DEVELOPMENT MUNICIPAL Dear Mr. Ach: PLANNING We have previously reviewed the proposed Automall, Mr. Movies, Little Caesar's Pizza proposed development on the Darkenwald property and commented in a letter dated April 15, STRUCTURAL 1994. At that time, we recommended that a traffic study be done to analyze the effects of this • proposed development on the intersection of Carson Street and Main Street. The developers SURVEYING have had a traffic study prepared for this proposed development by Benshoof and Associates. We have reviewed the traffic study and would offer the following comments: TRAFFIC 1. The traffic study analyzed two different alternatives for road alignment, one with a right- in/right-out at the north end of Carson Street on TH 169 and the second without a right- TRANSPORTATION in/right-out access point. We have had recent discussions with MnDOT regarding the TH 169 corridor relative to additional access points. MnDOT has informally proposed that a corridor study be prepared for TH 169 from the intersection of TH 101 to the north City limits. This corridor study would be a joint effort between MnDOT and the City and would take approximately 18 months to complete. MnDOT has indicated they would make no decisions on additional requests for access points until such a study was completed. Therefore, we believe it is best to analyze this development as if a right- in/right-out access on TH 169 will not be granted. 2. The traffic study indicates that the proposed development will generate approximately 1326 Energy Park Drive 160 trips in the p.m. peak hour leaving the site. In order to accommodate this increase St.Paul,MN 55108 in trips, the traffic study proposes improvements consisting of the widening of Carson 612-644-4389 Street to accommodate a right turn lane at Main Street and to add a 2-foot wide striped island between north and southbound traffic. This would result in a street width of 42 Fax:612-644-9446 feet. The current street is 30 feet wide. We concur with this recommendation and would add that the right turn lane should be a minimum of 300 feet long plus a taper 9800 Shelard Parkway section. We believe it needs to be long enough to accommodate several right turning Minneapolis,MN 55441 vehicles and also to preclude left turning vehicles from lining up and blocking access to the right turn lane. 612-546-0432 Fax:612-544-6398
