Grey Fox Road Redevelopment – Arden Hills Traffic Impact Analysis │ July 2021 8 The two site accesses were modeled with the existing geometry and intersection control. The intersection of Lexington Avenue & Grey Fox Road used the geometry and intersection control from the Lexington Avenue Reconstruction (I-694 to CR E) project. The traffic volumes are provided in Exhibit 4. The results of the analysis are provided in Table 3.

Additionally, all individual movements are anticipated to operate at a LOS D or better. The SimTraffic reports are provided in Appendix D. All 95th percentile queues are anticipated to remain within their respective storage bays. OPENING YEAR (2023) BUILD CONDITIONS Opening Year (2023) Build conditions were analyzed to determine any traffic impacts from the addition of the site traffic to the study intersections. The site accesses were modeled as side street stop control. Opening Year (2023) Build turning movement volumes were developed by adding the site trips in Exhibit 7 to the Opening Year (2023) No-Build turning movement volumes in Exhibit 4. The Opening Year (2023) Build turning movement volumes are shown in Exhibit 8. The results of the analysis are provided in Table 4.
