Attachment J Kimley»)Horn MEM ANDUM To: City of Arden Hills From: Jacob Rojer, P.E., PTOE Kimley-Horn and Associates, Inc. Date: December 12, 2023 Subject: Arden Hills Mister Car Wash — Trip Generation & Queuing Summary INTRODUCTION The proposed site is located at 3571 Lexington Avenue North in Arden Hills, Minnesota. The approximately 1.26-acre site is currently occupied by a fast-food restaurant. The proposed development includes a single car wash tunnel, 130' in length, that is served by 3 inbound lanes. The site will also have 5 parking spaces and 17 vacuum stalls. The existing site shares a site access with the retail building to the north. As part of the Lexington Avenue reconstruction, the only site access was converted to a right-in/right-out access. The proposed site plan is attached. This memorandum documents the anticipated trip generation of the proposed development, the anticipated queueing, and the peak operation times for the car wash. TRIP GENERATION The trip generation for the development was calculated based on data collected at a comparable Mister Car Wash location in Columbia Heights, MN. The data was collected on Thursday, April 21', 2022. The weather on the day of data collection was mid-50's and sunny, it is anticipated that trip generation and queuing data would be representative of a typical day. Table 1 provides the daily, AM, and PM peak hour trips for the proposed development based on the local data. It is anticipated that the Arden Hills location will operate similarly to the Columbia Heights location even though it is anticipated to have more payment stations and vacuum stalls, this is because there is still only one car wash tunnel proposed on the site. The Arden Hills Mister Car Wash is expected to generate approximately 1,560 daily trips, 99 AM peak hour trips (8:OOAM — 9:OOAM), and 190 PM peak hour trips (4:45PM — 5:45PM).
