Josh Nyquist,Executive Director of Building Operations May 26,2022 PACT Charter School I Traffic Impact Study Page 20 Based on field observations, engineering judgement and applicable standards, there is adequate sight distance at the proposed site access locations to clearly identify approaching vehicles. Consideration should be made to limit any sight distance impacts from future onsite structures, landscaping and signing. The proposed site plan is generally well configured and the proposed site access locations do not appear to represent any significant traffic safety or traffic operations concerns. Summary of Findings, Conclusions and Recommendations Based on this proposed PACT Charter School development traffic impact study and analysis, the following summary of findings, conclusions and recommendations is offered for your consideration: 1. Results of the existing weekday traffic operations analysis indicate that all study intersections currently operate at acceptable overall LOS B or better during the a.m. commuter (school arrival) peak hour (7:30-8:30 a.m.), school dismissal peak hour (2:30-3:30 p.m.) and p.m. commuter peak hour (4:00-5:00 p.m.), under existing traffic control and intersection geometrics. No significant queuing or delay issues were identified, except at the Armstrong Boulevard/Alpine Drive intersection where the westbound approach is operating at a LOS E during the p.m. peak hour. The future conversion of Armstrong Boulevard/Alpine Drive to a single-lane roundabout will improve the operations and all approaches will operate at a LOS A during the peak hours. 2. The segment of 161 st Avenue between Armstrong Boulevard and Variolite Street has been identified to be improved/reconstructed as part of the City of Ramsey Capital Improvements Plan for year 2024. Design of this future 161 st Avenue improvement/reconstruction is currently under consideration. It has been suggested that it may be possible to reschedule this 161 st Avenue improvement and/or reconstruction to coincide with the proposed PACT Charter School project. 3. An annual growth rate of one percent was applied to the existing peak hour traffic volumes to develop year 2028 background traffic forecasts (no proposed PACT Charter School site-generated traffic is included in this scenario). Note that year 2028 represents the year where the PACT Charter School can be assumed to be completed with full occupancy of the proposed development and includes all phases of the proposed PACT Charter School project plus completion of the adjacent future proposed St. Katharine Drexel Church. 4. Results of the year 2028 no-build intersection capacity analysis 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 the operations and all approaches will operate at a LOS A during the peak hours. 5.
