-� Memorandum to Jeff Agnes and Jamie Swanson Subject: Supplemental Traffic Review for Outlot 81 Concep[ PUU for Har Mar Shopping Center Page 6 of 9 November I5, 2007 LVAI.UATION AND CONCLUSIONS As presented earlier, the follawing are ihe two points raised by City staff as reasons to su��est remaval of the riQ,ht-out at the existina westerly right twn access on County Road B as a condition for approval of the PUD for o�tlot 81 : c) Safety problems �resently occur due ta motorists who make a right tiun onto County Road B at the wescerly right turn access and then make a U-tui7� at the main access for the Har A.•ar sl:opping ce:zter. d) The existing safety probiems would worsen with the proposed PUD for outlot 81. The data and volume forecast,ti previously presented have been analyzed relative to the precedina concerns raised by staff. Our firdings are presented next. Existiu� Safetv Conditions Based on our review, the existing iight turns ouc at the westerly right tum access and eastbound u-turns at the main access are operating at a high level of safety for the following reasons: • In the last five years, only one crash ai the Cowity Road B/main access intecsection involved a u-turn. • No segment-related crashes were reported on County Road B between the westerly right turn access and the main lccess. • No crashes were reported at the westerly right turn access in the last five yean that involved an exiting right turn movement (northbound riaht turn}, • From actual field observ�tions for a period of ei�ht typical busy hours, all eastbound u- turns at the County Road B/main access intersection wEre completed in one maneuver. • No weaving was observed between right ttu�ns exiting at the westerly right turn access that are dettined to make a left turn or a u-turn at the main access and eastbound through movements on County Road B. One of the concerns raised Uy City staff was violation of the u-[urn prohibition between I 1:(}0 a.m. and 1:00 p.m. and between 4:0(} �.m. and 6:00 p.m. on weekdays. Our iietd data summarized in Table 1 confirms that significant violations occur. The City may consider one of two possible measures to resolve these u-turn violatio�ls: � Increase enforcement during time pec•iods when u-turns are prohibited. OR • Re�nove the u-turn restriction and altow u-tui•ns at all times.
