Lexington Station Phase 3 Traffic Study February 26, 2021 Page 7 Year 2023 No Build Conditions To understand how the planned transportation improvements and general background growth are expected to impact the study intersections, year 2023 no build conditions were reviewed. Note that the year 2023 represents one-year post construction of the proposed development and includes the Lexington Avenue reconstruction project. GGeneral Background Growth To account for general background growth in the area, an annual growth rate of one-half percent was applied to the existing peak hour traffic volumes to develop year 2023 background traffic forecasts. This growth rate is consistent with future traffic volume projections identified in the City of Arden Hills – 2040 Comprehensive Plan and with historical growth in the study area based on MnDOT AADT volumes. Intersection Capacity Analysis To determine how the adjacent roadway network will accommodate the year 2023 no build traffic volumes, an intersection capacity analysis was completed using Synchro/SimTraffic Software. Year 2023 no build traffic forecasts, which include general background growth and the planned transportation improvements, are shown in Figure 3. As mentioned previously, the Lexington Avenue reconstruction project was assumed, and signal timing was optimized. Due to the unknown timing of traffic control improvements at the Lexington Avenue/Target Road intersection, the intersection was analyzed with and without a traffic signal. Note this access is expected to be one of the primary access locations to the proposed development. Results of the year 2023 no build intersection capacity analysis, shown in Table 4, indicate that all intersections are expected to operate at a LOS C or better during peak hours. With the reconstruction project, the Lexington Avenue/Red Fox Road intersection is expected to improve from an overall LOS D to a LOS C during the p.m. peak hour. In addition, queueing on all approaches of the intersection are expected to be reduced, and the maximum southbound left-turn queue not expected to extend beyond the proposed dual-lane storage. Without a traffic signal, the west leg addition and general background traffic are expected to increase side-street delays at the Lexington Avenue/Target Road intersection by approximately eight (8) seconds.
