-� Memorandum to Jeff A�nes and Jamie Swanson Subject: Supplementa] Traffic Review for Outlot S1 Concepc PUD for Har Mar Shopping Center Page 3 of 9 November I5, 2007 In addition to traffic counts, we completed observations at the site to identify any problems regarding the followin�: Weaving on County Road B involvin� motorists who make right turns out at the westerly right turn access and then either turn left oc make a u-turn at the main access. Abilily of eastbound u-turn motoris[s at thc County Road B/main access intersection t� comptete the turn in one maneuver (without having to stop and back up to complete the u-turn). Conflicts between eastbound u-turns and westbound through movements. Based on our obseivations at the site, we did not find �►ny issues associated with the above three elements. No weaving patterns were observed on County Road B because right turns out at the westerly right turn access that were destined to make a left turn or a u-turn at the main access turned only when there were gaps in both eastbound ttu•ough lanes. When all Ehose motorists exited from the site, they did not weave with eastUound traffic, but rather turned promptly into the inside through lane and then maneuvered into the eastbound left curn lane. During the eight hours for which we collected data, every u-turn that was made was completed in one maneuver, without the need to stop and back up in the middle of the intersection. We did not observe any abrupt stopping or slowin� of westbound through motorists due to the eastbound u-turn maneuvers. Crash Data for County Road B hetwee.n Westerly RiQh[ Tucn Access and Main Access To determine whether there are any existing safety concerns at the County Road B intersections with the westerly right turn access and the main access, and on the segment in between these two intersections, we obtained crash data for the last five yeac•s� from the Minnesota Department of Transportation. The follawing are the principal summaiy points from the crash data that pertain to com►nents raised by City staff regarding safety issues associated with rigl�t tu�-�is out at the westerly right turn access and eastbound u-turns at the main access: • There was only one reported crash that involved an eastbound u-turn at the County Road B/main access intersection in the last fivc years. In that crash, a westbound through motorist collided with a motorist making au eastbound u-turn. The factors reported for that crash were dri��er inexperience (the u-turn motorist was 17 years oid) and failure to yield right-of-way. • The data shows no reported crashes in the last five years at the County Road B/westerly right turn access i.ntersection. that involved a riaht turn movement exitii�g the Har Mar shopping center. • There were no segiiient-related crashes that occurred in the last five years on County Road B between the westerly right turn access and the main access. � Prior to Summer 200�, full access �vas availablc at the location �vhere the `vesterly right tw�n access prescntly eaists. The median opening at that location was closed in summcr 200� tci restrict the movements to right turns only.
