Josh Nyquist,Executive Director of Building Operations May 26,2022 PACT Charter School I Traffic Impact Study Page 10 Results of the year 2028 no-build intersection capacity analysis shown in Table 4,indicate that all study intersections are expected to continue to operate at an acceptable overall LOS B or better during the peak hours under existing traffic control and intersection geometrics. No significant queuing or delay issues were identified, except for the Armstrong Boulevard/Alpine Drive intersection where the westbound approach would now operate at a LOS F during the p.m. peak hour (note: no proposed PACT Charter School site-generated traffic is included in this scenario). The future conversion of Armstrong Boulevard/Alpine Drive to a single-lane roundabout will improve operations and all approaches will operate at a LOS A during the peak hours. Table 4.

EB/1 (1) Indicates a side-street stop-controlled intersection,where the overall LOS is shown followed by the worst approach LOS.The delay shown represents the worst side-street approach average delay per vehicle.The queue shown is the 95th percentile queue(in vehicles)for the worst approach at the intersection. The 95th percentile queues shown in red bold font spill back to and beyond the adjacent upstream intersection. (2) Indicates an all-way stop-controlled intersection,where the overall LOS and average delay per vehicle are shown.The queue shown is the 95th percentile queue(in vehicles)for the worst side-street approach at the intersection.The 95th percentile queues shown in red bold font spill back to and beyond the adjacent upstream intersection. (3) Indicates an improvement to provide a single-lane roundabout intersection,where the overall LOS and average delay per vehicle are shown.The queue shown is the 95th percentile queue(in vehicles)for the worst side-street approach at the intersection.The 95th percentile queues shown in red bold font spill back to and beyond the adjacent upstream intersection. Proposed Development The site of the proposed PACT Charter School development is generally located north of 161 st Avenue and roughly 0.25 miles east of Armstrong Boulevard (see Figure 1). It was assumed that the construction of the proposed development would be completed and fully occupied by year 2028. Access to the proposed site would be provided at two site access locations on 161 st Street: a primary (east) site access approximately 600 feet west of Variolite Street (buses, pick-up/drop-off, stafo and a secondary (west) site access approximately 1,150 feet west of Variolite Street (buses, student drivers). PACT Charter School is proposing to acquire approximately 18 acres of a larger 33-acre vacant land parcel located at 7633 161 st Avenue NW in the City of Ramsey,with the intent to build a new charter school facility, approximately 115,000 square feet in size. This new facility will be designed to accommodate grades six through twelve. The schools existing campus will then be home to kindergarten through fifth grades. Minor interior renovations are being planned at their existing building to better accommodate these lower grade levels. The seller is the Church of St. Katharine Drexel and they plan to retain the remaining approximately 15 acres for a future church development.
