Memorandum to Dennis Trooien, Dennis Properties Subject: Traffic and Parking Study for Proposed Redevelopment of Arden Plaza Page 11 of 15 September 17, 2007 Traffic Safetv on Countv Road E, Lexington Avenue, and at Countv Road E/Lexington Avenue Intersection (question c) To examine traffic safety, we obtained crash data from the Minnesota Department of Transportation for County Road E and Lexington A venue along the frontage of the subject site and at the County Road E/Lexington A venue intersection for the past five years (2002 to 2006). Based on these crash data, there was only one reported crash (possible injury) at the site access on Lexington Avenue. No crashes were reported at the site access on County Road E. There were a total of 74 reported crashes at the County Road E/Lexington A venue intersection. Since the proposed development will increase the traffic volume at the County Road E/Lexington A venue intersection by only 2.7 percent. the crash frequency at this intersection is not expected to change significantly. A total of two "segment" crashes were reported on Lexington Avenue between County Road E and the site access. Since the proposed development will not significantly alter the traffic volumes, no significant changes are expected in crash frequency on that segment of Lexington A venue. One concern that was raised at the Planning Commission meeting on August 1 was regarding the safety impacts of "weaving" maneuvers due to motorists exiting at the access on County Road E to turn right on to County Road E and then change lanes to turn left on to Lexington Avenue. Based on our review, these maneuvers are not expected to cause any negative safety impacts on County Road E for the following reasons: . Those maneuvers are not truly weaving maneuvers becanse motorists exiting the site will turn only when there is a gap in eastbound through traffic. . The crash data shows no reported "segment" crashes in the past five years on County Road E between the site access and Lexington A venue. Adequacv of Internal Traffic and Parking Operations (question d) We reviewed the adequacy of the current site plan with respect to the following three items: . Overall adequacy of proposed parking supply . Relatively high parking demand at the south end of the site . Head-in parking along the east edge of the existing retail building . Drive-through queuing for the proposed pharmacy Results of our review regarding each of the above four items are presented next: . Overall adequacy of proposed parking supply. Our parking review was based on the City's Zoning Code requirements and data presented in the Institute of Transportation Engineers' Parking Generation, Third Edition. Results of our review are presented next.
