5 NorthPoint Industrial Park – Lake Elmo, MN │Traffic Analysis January 2022 The study area intersections include Ideal Avenue N & 36th Street N, Ideal Avenue N & 34th Street N, Ideal Avenue N & 32nd Street N, Ideal Avenue N & 31st Street N, Ideal Avenue N & Stillwater Boulevard N, and 34th Street N & Jamaca Avenue N / Stillwater Boulevard N. 3.0 FUTURE CONDITIONS It is assumed that the 84-acre industrial development will be fully built out by the Opening Year (2025). By the Horizon Year (2040), it is assumed the 96-acre parcel to the north will be developed for a mix of residential, commercial, and industrial use. Therefore, intersection turning movement volumes were projected for the Opening Year (2025) and Horizon Year (2040) based on the data collected in August 2021. The future volume forecast accounted for background growth in regional traffic volumes as well as including traffic from the Willowbrooke development which is under construction. 3.1 FUTURE ROADWAY AND INTERSECTION IMPROVEMENTS Washington County is planning a future roadway improvement that will impact the surrounding transportation network. County Highway 13 (Ideal Avenue) Phase II is a pavement and safety improvement project, which will change the roadway geometry on Ideal Avenue N, between 36th Street N & 44th Street N. The only study intersection that will be affected is the intersection of Ideal Avenue N & 36th Street N. The following describes the proposed changes at the intersection of Ideal Avenue N & 36th Street N: • Add a northbound right turn lane • Add a southbound right turn lane • Buildout the westbound approach to have a shared left -through lane and a shared through-right turn lane. • The westbound approach will be realigned to be an east -wes t roadway, with an access point for the Lake Elmo Public Works Driveway The proposed roadway improvements are planned for construction in 2022, the improvements were included in the Opening Year (2025) and Horizon Year (2040) conditions. No other roadway improvement projects are currently planned in the study area. 3.2 FUTURE TRAFFIC FORECASTING Background growth was based on a review of historic AADT volumes and projected 2040 AADT volumes provided in the Lake Elmo 2040 Comprehensive Plan. The 2040 Projec tions are also consistent with projections from the Washington County 2040 Comprehensive Plan. Historic (2015) and projected (2040) AADT volumes for existing roadways within the study area are summarized in Table 1. Based on the data, this study assumed an average annual growth rate of 1.0 percent for 34th Street N and 1.5 percent for Ideal Avenue N & Stillwater Boulevard N. No growth rate was applied to the remaining roads in the study area.
