RECEIVED ► ;_G ; 0 19€9' Ramsey County DEPARTMENT OF PUBLIC WORKS 3377 North Rice Street Saint Paul, Minnesota 55126 (612) 484-9104 February 8, 1989 Karl P. Keel Assistant Public Works Director City of Roseville 2660 Civic Center Drive Roseville, MN 55113 Traffic Impact Analysis Rosedale/Welsh Subdivision Divisions of: Engineering Maintenance Mobile Equipment Environmental Services The Ramsey County Public Works Department has reviewed the traffic impact analysis prepared by BRW for the expansion of Pavilion Place. The County wishes to offer the following comments relative to the development's impact on Ramsey County roadways: 1. We are not in disagreement with the traffic volumes presented in the report. The existing volumes agree with Ramsey County data and the proposed volumes appear consistent with similar developments. 2. Ramsey County does not own controlled access along County Road 13-2; therefore, an access to this development could not be denied basest on that reason. 3. The County has the following comments in regard to the design of the right in -right c►ut ticcess off County Road B-2. - the proposed design tallowy vehicles to snake a right turn onto the site and then decide whether to go right or left into the parking lot. Also, vehicles turning into tine site must conflict with vehicles left turning out of the site. This access would function more efficiently if vehicles entering the site did not have to make a decision and were forced to continue with a right turn until they were well within the parking area. This would eliminate confusion directly at the access point and reduce the possibility of backup onto County Road B-2. The majority of vehicles entering tilt~ site at the right in -right out access will tilso exit at this point. Many of the vehicles exiting froln this driveway will want to travel eastbound on County Road U-2 or enter the Rosedale Mall; therefore, merging with thru traffic and weaving into the eastbound left turn lane tit American Street. This is anticipated to cause problems because the distance in which vehicles can make this weave is short and all increase in U-turns at tie signal will reduce the capacity of the intersection.
