Chick-fil-A - Arden Hills, MN | Traffic Study March 26, 2021 Page 6 Planned Transportation Improvements Ramsey County has programmed a reconstruction project for Lexington Avenue from County Road E to I-694. The reconstruction project includes replacing aging and deteriorating pavement, replacing traffic signals, and improving pedestrian and bicycle facilities. As part of the reconstruction project, Lexington Avenue will be converted from a 5-lane undivided roadway to a 4- lane divided roadway with left- and right-turn lanes. Dual southbound left-turn lanes and an eastbound right-turn lane are planned to be constructed at the Lexington Avenue/Red Fox Road intersection, which are expected to mitigate existing queuing issues at the intersection. In addition, access management strategies will be implemented along the corridor. The reconstruction project is expected to be completed by 2023, therefore, for the purpose of this study, the reconstruction project was assumed under year 2023 no build and build conditions. 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. General Background Traffic 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. The proposed Lexington Station Phase 3 development-generated traffic was also included. 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 computer model. 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.
