V. SUMMARY AND SUGGESTIONS The preceding analysis has evaluated the potential traffic impacts of the proposed development of the Sotarra-Trott Brook residential project,on the operations of the study area intersections. The site is located adjacent to the west side of Nowthen Boulevard NW and east side of Variolite Street NW just north of Trott Brook and south of 173rd Avenue NW in Ramsey, Minnesota. Two design years were considered in this study,2026 to correspond to the year after build-out and 2040 to remain consistent with the long range planning horizon. For both design years a No-Build and Build scenario, was analyzed and compared to assess the development's impact, and the area's future infrastructure needs. Development of the Sotarra - Trott Brook residential project on the site by 2026 is expected to result in approximately 2,593 new vehicle trips on the study area roadway network per average weekday. Peak hour trips generated by the development are estimated at 196 during the AM peak hour and 264 during the PM peak hour. The site access will include the extension 173rd Avenue NW westward from Nowthen Boulevard NW into the site and the construction of a new intersection on Variolite Street NW at approximately 170th Avenue NW. It is assumed the new 170th Avenue NW intersection with Variolite Street NW will include a dedicated northbound right turn lane and a southbound left turn by-pass lane on Variolite Street NW. Growth in background traffic at a rate of 1.0 percent per year was accounted for in the analysis. Results of the operational analyses in the 2026 and 2040 No-Build and 2026 and 2040 Build scenarios indicate all the intersections will operate at acceptable levels of service with typical Peak Hour short to moderate vehicle queues. It is recommended that the new intersection at 170th Avenue NW and Variolite Street include a northbound right turn lane and a southbound left turn by-pass lane,and it is recommended the 173 rd Avenue NW approach to Nowthen Boulevard include a dedicated right turn lane.
