Trott Brook Crossing EAW Traffic Study Review January 6, 2022 <br />Proposed Development <br />The proposed Trott Brook Crossing development, shown in Figure 3, is proposed to be constructed <br />in the southwest quadrant of the Nowthen Boulevard NW and 173rd Avenue NW intersection. The <br />site is expected to include 270 single family units. Access to the development is proposed to be <br />constructed on Variolite Street NW approximately 500 feet north of 169th Lane NW. A second access <br />will be shared with the adjacent North Brook Meadows housing development on 173rd Avenue NW. <br />Traffic Forecasts <br />To identify potential impacts associated with the proposed development, traffic forecasts for year <br />2026 and 2040 conditions were developed to understand both short-term and long-term conditions. <br />The no build conditions take into account traffic generated by the adjacent North Brook Meadow <br />development and background traffic growth. The build conditions will take into account traffic <br />generated by the proposed Trott Brook Crossing development, adjacent North Brook Meadow <br />development and background traffic growth. <br />Background Growth <br />Based on existing area growth patterns and historical ADT volumes, a conservative annual growth <br />rate of one (1) percent was applied to the existing peak hour volumes to develop year 2026 and 2040 <br />background traffic forecasts. <br />Adjacent Developments <br />There is one known development planned in this area. The North Brook Meadows development, <br />located immediately north of the proposed development, consists of 77 single family housing units. A <br />shared access with the proposed development is provided on 173rd Ave NW. As part of the adjacent <br />development plan, the North Brook Meadows development is expected to have a second access <br />approximately 750 feet to the west of the Nowthen Boulevard NW and 175th Avenue NW <br />intersection. For the purpose of this study, the adjacent development was assumed to be completed <br />by the year 2025. <br />Trip Generation <br />To account for traffic impacts associated with the proposed and adjacent development, trip generation <br />estimates for the proposed land uses were developed for the a.m. and p.m. peak hours as well as on a <br />daily basis. These estimates, shown in Table 4, were developed using the Institute of Transportation <br />Engineers (ITE) Trip Generation Manual, Tenth Edition. Note that no multi -use or pass -by reductions were <br />applied due to the residential nature of the proposed development. <br />Page 6 <br />
