Trott Brook Crossing EAW Traffic Study Review January 6, 2022 <br />While the intersections are expected to operate acceptably overall, there are side -street delays that <br />reach a LOS E at the Nowthen Boulevard and Ramsey Boulevard intersection. The following <br />information summarizes the operational and/or queuing issues that warrant consideration as traffic <br />volumes increase. <br />• Nowthen Boulevard NW / Ramsey Boulevard NW <br />o The side -street delay in the eastbound direction is 12 seconds for the a.m. peak and 39 seconds <br />for the p.m. peak hour. The 95th percentile queues in the eastbound direction are expected to <br />be approximately 60 feet during the a.m. peak hour and 250 feet during the p.m. peak hour. <br />o Side -street delay is expected to increase by approximately two (2) seconds per vehicle during <br />the a.m. peak and 20 seconds per vehicle during the p.m. peak as compared to year 2026 no <br />build conditions. <br />• Nowthen Boulevard NW / 167th Avenue NW <br />o The side -street delay in the westbound direction is eight (8) seconds for the a.m. peak and 29 <br />seconds for the p.m. peak hour. The 95th percentile queues in the eastbound and westbound <br />directions are expected to be less than 100 feet during both the a.m. and p.m. peak hours. <br />o Side -street delay is expected to increase by approximately two (2) seconds per vehicle during <br />the a.m. peak and 12 seconds per vehicle during the p.m. peak as compared to year 2026 no <br />build conditions. <br />• Nowthen Boulevard NW / 173rd Avenue NW (Proposed Access) <br />o The side -street delay in the eastbound direction is seven (7) seconds for the a.m. peak and six <br />(6) seconds for the p.m. peak hour. The 95th percentile queues in the eastbound direction are <br />expected to be approximately 75 feet during the a.m. peak hour and 60 feet during the p.m. <br />peak hour. <br />The remaining intersections had minimal changes to their traffic operations compared to year 2026 <br />no build conditions While the side -street delays along Ramsey Boulevard NW are expected to reach <br />nearly 40 seconds, this type of delay is not uncommon during the p.m. peak hour for side -streets in <br />developing or developed areas and no traffic control or geometric mitigation would be necessary for <br />year 2026 build conditions. <br />Year 2040 Build Conditions <br />Results of the year 2040 build conditions intersection capacity analysis shown in Table 8 indicates that <br />the study intersections are expected to continue operating at an overall LOS C or better during the <br />a.m. and p.m. peak hours with the proposed roadway geometry and traffic controls. <br />Page 17 <br />
