condition. Table 3 summarizes the operational analyses results for the 2026 Build conditions. Note it is assumed the new intersection at Variolite Street NW and 170th Avenue NW will include a dedicated northbound right turn lane and a southbound left turn by-pass lane, and the 173 rd Avenue NW approach to Nowthen Boulevard will include a dedicated right turn lane.

Overall Level of Service reported from SimTraffic delay,first letter represents intersection LOS,while second letter represents worst LOS of individual approach.Upper case letters indicate signalized intersection,and lower-case letters indicate unsignalized intersection. 2. 95th percentile queues are a result from an average of 10 SimTraffic simulations. The results shown in Table 3 indicate all intersections and worst movements are expected to operate at acceptable LOS in 2026 with the proposed project. Further, the results indicate all intersections will experience short vehicle queues. (Again, when the operations of the intersection and critical movements are at LOS A. the random number generator can sometimes show slightly better delay or queuing results on minor movements even with higher traffic conditions.) F. 2040 Operations The long-range planning horizon year is 2040, as mentioned in the No-Build section.
