The product of this task will be a traffic report that identifies the appropriate lane configuration for the intersection of Sunwood Boulevard /Ramsey Parkway and Armstrong Boulevard and the appropriate spacing with the next intersection to the east in order to maintain an acceptable level of service. The report will also evaluate the warrants for a traffic signal at the Sunwood Boulevard /Ramsey Parkway and Armstrong Boulevard Intersection. WSB will submit the report to Anoka County for their review and comment and incorporate changes as appropriate. 2.0 Prepare Feasibility Study for Intersection Improvements The feasibility study would develop a concept design and cost to construct an intersection at Sunwood /Ramsey Parkway and Armstrong Boulevard that fits with both the future preferred interchange design for Armstrong Boulevard and TH 10 and the existing roadway system. The feasibility study will evaluate the storm water needs, utility relocation or reconstruction needs, number and configuration of lanes, horizontal and vertical alignments, right -of -way needs, construction costs, and funding. A layout for review by Anoka County would be prepared as part of the feasibility study. We anticipate one meeting with Anoka County staff to review the assumptions and design. We will submit a layout to the County for review and comment and will make changes as appropriate to address their comments. We will utilize existing survey and topographic data for the feasibility study. We do not propose to conduct additional survey at this point. We will also utilize the existing geotechnical data for the corridor for determining the roadway pavement section and earthwork needs for the project. We anticipate that there may be some retaining wall needs for the project. Final Design and Construction Plans 3.0 Prepare SJR Mr. Tim Himmer, PE July 20, 2011 Page 2 This work assumes that the limits for the final design and construction plans for Armstrong Boulevard are from approximately 500 feet north of 147 to just north of the BNSF railroad crossing. It is assumed that the project will not involve work in the railroad right -of -way. It is assumed that some retaining wall will be required along Armstrong Boulevard south of 147 and that some relocation of existing utilities will be required to accommodate the retaining walls. It is assumed that the project will include the preparation of signal plans. WSB will prepare a signal justification report for the intersection of Sunwood Boulevard /Ramsey Parkway and Armstrong Boulevard that will take into account the existing traffic plus the traffic from any approved development in the area. 4.0 Prepare Right - of -way Plans and Parcel Descriptions WSB will prepare the right -of -way plans and parcel descriptions necessary to acquire the strip takings along Armstrong Boulevard needed for the project. 5.0 Assist in Right -of -Way Acquisition WSB will obtain appraisals for the strip takings and 6.0 Complete Final Design and Prepare Construction Plans WSB will complete the final design and construction plans for the intersection of Sunwood Boulevard /Ramsey Parkway and Armstrong Boulevard. The plans will include the areas adjacent to Armstrong Boulevard and will be coordinated with the design for the proposed development and the Sunwood /Ramsey Parkway improvements being developed by others.
