1 | P a g e Scooters Coffee, Mankato, MN September 25, 2022 To: Pat Briggs, The Briggs Companies From: Vernon Swing, PE Re: Traffic Study – Jackson Hills Apartments – Phase 2-4, Elk River, MN Per your request, S2 Traffic Solutions, LLC has reviewed the traffic impacts associated with the completion of phase 2-4 of the Jackson Hills Apartments (hereafter referred to as Proposed Project) in Elk River, MN. The Proposed Project will complete 132 low-rise multi-family apartment units, and will be accessed via 4 driveways, two from Jackson Ave NW and two from 6th Street NW, however, for the purposes of this analysis the site access is assumed to occur at one location directly from Jackson Ave NW. The site is located adjacent to the west side of Jackson Ave NW and is south of School St NW, and for the purposes of this analysis the Proposed Project is expected to be fully occupied by 2025. (See Attached Vicinity Map and Site Plan.) To determine the impacts to the traffic capacity of Jackson Ave from the Proposed Project, traffic data collected by MnDOT was acquired, the trip generation of the proposed use was forecast, and traffic queuing analysis was conducted. This memorandum summarizes the findings. Traffic Counts The traffic data used in this study was acquired by S2 Traffic Solutions from MnDOT including AM and PM peak hour turning movement counts at the intersections of Jackson Ave NW and TH 10, Jackson Ave NW and TH 169, and School St NW and Freeport Ave NW. These counts were used to estimate the existing traffic conditions at Jackson Ave NW and School St NW. The existing traffic volumes are shown on the Figures Below. Also, the daily traffic volumes from MnDOT (5200 trips per day) on Jackson Avenue near the site are used to identify the roadway capacity with and without the project.
