St. Cloud  Minneapolis  St. Paul Equal Opportunity Employer wsbeng.com Technical Memorandum To: Michael Grochala, Copy: Diane Hankee PE, City Engineer Community Development Director Katie Larsen, City Planner City of Lino Lakes City of Lino Lakes From: Chuck Rickart, PE, PTOE File: WSB No. 2029-22 Traffic Engineer Date: August 15, 2016 Subject: St. Clair Estates Traffic/Access Review The St Clair Land Company is proposing the St Clair Estates residential development north of Birch Street and east of Hokah Drive in the City of Lino Lakes. Through the preliminary review process questions have arisen with respect to the level of traffic on the adjacent City streets, specifically: Sioux Lane between Hokah Drive and Ware Road, and; Hokah Drive between the new site access (Enid Trail) and Birch Street. The purpose of this memorandum is to:  Document the access alternatives discussed;  Document the level of traffic on the associated streets, and;  Discuss conclusions of the potential impact. The original Traffic Study prepared for the development documented the existing and projected traffic volumes assuming a new cul-de-sac street (Enid Trail) with access to Hokah Drive and no other improvements to the area streets. The study documented that the proposed development would generate an additional 334 new daily trips on the area streets. A revised Traffic Study was prepared for the proposed development based on preliminary comments from City staff. The study was then revised to document the traffic volumes assuming that Hokah Drive at Birch Street was a future right-in/right-out access as proposed in the Anoka County Highway Department CSAH 34 Corridor Study. This moved all traffic (new and existing) that would be making left turns to or from Hokah Drive at Birch Street to Ware Road at Birch Street and ultimately Sioux Lane. After discussions with Anoka County, a third access alternative was reviewed that would extend the new development street (Enid Trail) to a ¾ access at Birch Street as part of an Anoka County Highway Department larger corridor safety improvement project . Hokah Drive at Birch Street would be maintained as right-in/right-out access. Table 1 below shows the anticipated full build daily traffic volume with each access scenario.
