WSB & Associates, Inc. Infrastructure • Engineering • Planning • Construction July 20, 2011 Mr. Tim Himmer, PE City Engineer City of Ramsey 7550 Sunwood Drive NW Ramsey, MN 55303 701 Xenia Avenue South Suite 300 Minneapolis, MN 55416 Tel: 763 - 541 -4800 Fax: 763 - 541 -1700 Re: Proposal for Armstrong Boulevard and Sunwood Boulevard /Ramsey Parkway Intersection Design Dear Mr. Himmer: OVERVIEW The City of Ramsey has recently received a major development proposal in the COR area at the southeast quadrant of CSAH 116 and Armstrong Boulevard. The development proposal will include the realignment of Sunwood Boulevard /Ramsey Parkway and its intersection with Armstrong Boulevard. The current preferred alternative for the Armstrong Boulevard and TH 10 Interchange study involves the realignment of Sunwood Boulevard to the north to approximately 147 Avenue. Landform is developing a plan that would accommodate this realignment of Sunwood Boulevard and the proposed development. The current proposal would shift the new intersection of Sunwood Boulevard /Ramsey Parkway and Armstrong Boulevard approximately 70 feet south of the existing 147 Avenue intersection with Armstrong Boulevard. It is the City's desire to construct the new intersection of Sunwood Boulevard /Ramsey Parkway and Armstrong Boulevard in its future permanent location based on the preferred alternative for the Armstrong Boulevard and TH 10 Interchange. The purpose of this work is to determine the appropriate design for the intersection and determine how much of the intersection can be built consistent with the future plans and the construction cost. The work would include analysis of the storm water, sanitary sewer and utility relocation requirements for the project as well as determining the right -of -way needs and costs for the project. The work is broken into two phases; the Traffic Study and Feasibility Phase and the Final Design and Construction Plans. SCOPE OF SERVICES Traffic Study and Feasibility Phase 1.0: Update 2030 Traffic Forecasts and Traffic Operations Analysis Review the land use, traffic forecasts, and traffic operations analysis being completed by Landform relative to the previous 2030 traffic forecasts for the TH 10 and Armstrong Boulevard Study and the CSAH 116 and Armstrong Boulevard final design. Make appropriate changes to the previous traffic forecasts to reflect the updated land use and transportation system changes identified for the proposed development while maintaining consistency with the forecasts previously presented for the project area. Update the traffic operations analysis for the project area based on the revised forecasts to determine potential changes in number and length of turn lanes at the Sunwood Boulevard /Ramsey Parkway and Armstrong Boulevard Intersection. The updated analysis would include the first intersection to the east of Armstrong Boulevard on Sunwood Boulevard /Ramsey Parkway to assure that there is adequate spacing to accommodate vehicle queues between intersections.
