St Clair Estates Traffic/Access Review 2 | Page Table 1 – Access Scenarios Daily Traffic Volumes Sioux Ln - Hokah Dr to Ware Rd Hokah Dr – Enid Tr to Birch St Enid Tr – to Birch St Existing 520 270 NA Projected – St Clair Estates Project 670 455 0 Projected - RI/RO at Hokah Dr 950 175 0 Projected – RI/RO at Hokah Dr and ¾ at Enid Tr 830 110 185 Based on the existing and projected traffic volumes the following can be concluded:  Traffic generated from the proposed St Clair Estates does not warrant direct access to Birch Street.  The level of daily traffic volumes on each of the associated streets with any of the access scenarios is typical for a local city street. Typically local city streets can accommodate traffic volumes of 1000 vehicles per day or less.  The proposed St Clair Estates initial access scenario with 670 vehicles on Sioux Lane and 455 vehicles on Hokah Dr and no restrictions to intersections on Birch Street provides the best local distribution of traffic to the existing street system.  In the future the access scenarios restricting access to and from Birch Street with an Anoka County Highway Department safety improvement project will reduce traffic on Hokah Drive but increase traffic on Sioux Lane.  The extension of Enid Trail will not significantly change the traffic levels on any of the area streets. Anoka County would need to evaluate whether the benefit to Birch Street would warrant the Changes.  Environmental impacts of extending Enid Trail to Birch Street through the wetland/lake.  The City should work with Anoka County on when and how any access restrictions would be implemented on Birch Street.
