Main Office: 3601 Thurston Avenue, Anoka, MN 55303 Phone: 763/427-5860 www.haa-inc.com MEMORANDUM TO:Danielle Sanborn, Anoka County Parks Department CC:Karen Blaska, Anoka County Parks Department Tim Eggerichs, Hakanson Anderson FROM:Shane Nelson, Project Manager DATE:October 5, 2023 RE:Traffic ControlAlternatives Rice Creek Chain of Lakes ParkReserveReconstruction Project As requested, we have reviewedalternatives for providing trafficcontrol for theRice Creek Chain of Lakes Park Reserve project that is scheduled for construction in 2024. The project consists of reconstruction of the park entrance road, boat launch parking lot, public beach parking lot, boat launch access road, and boat launch. The park will remain open during construction, and therefore it will be necessaryfor the Contractor to provide traffic control for various stages of the project. The park entrance road is proposed to be raised with fill to provide greater separation from the saturated soils, which willincrease stabilityof the road bed. While the road is being raised with fill, maintaining two way traffic on the roadway is not recommended. Although the designis still being finalized, our preliminary estimatefor the constructionperiod of the entire project is 12 weeks. Our preliminaryestimate for the construction period of the park entrance road, from Main Street to the campground entrance road, is 4-5weekswith good weather. The total lengthof the entrance road, from Main Street to the campground road,is approximately 3,800 feet. The following working days are assumedfor reconstruction of this segment of thepark entrance road: Reclaim Existing Bituminous Pavement1 Day Fill and Cap Roadway w/Gravel (500 feet / day)8 Days Concrete Ribbon Curb(Alternate Bid)4 Days Aggregate Base Tolerancing 2Days Paving Base Course1 Day Float Day1 Day Total Estimated Working Days17 Days Option 1. The first option for traffic control during construction of this segment ofthepark entrance road is to maintainone-way traffic by temporarily detouring traffic onto the trail corridor that is adjacent tothe roadway. If this option is chosen, it will be necessary for the Contractor to have flaggers on either end of the work areato prevent vehicles from meeting each other head on. It is anticipatedthatthe flaggers would be present during normal work hours, and that theContractor wouldre-open the park entrance road to at least a gravel surfaceat the end of each working day.
