Discussion As the environmental documentation and preliminary design process for the TH 10/CSAH 96 proj ect nears completion, staff recommends retaining Bolton & Menk's services. The ability to review the technical aspects involved with this transportation proj ect are an expertise that small cities do not typically have in house; Bolton & Menk has staff with the expertise needed to provide a thorough re�view of the information presented by Ramsey County and their consultant. The environmental assessment (EA) is anticipated to be posted for public comment in January, 2010. The EA has been submitted to Mn/DOT for initial internal review; following this review, Ramsey County will formally distribute the EA for public comment. Staff recommends assistance with the review of this document, similar to the review of the I-694 EA that was completed in 2007. Bolton & Menk has staff inembers with expertise to review the following aspects of the EA: ■ Geometric Designs ■ Traffic- Freeway Modeling, Local Traf� c ■ Social, Economic and Environmental Impacts ■ Water Resources ■ Land Use, Right of Way Impacts The review of the EA, assisting with the public involvement process for the EA, and continued participation in monthly proj ect meetings, are included as Task 1 in the attached proposal from Bolton & Menk to provide continued services. This work is anticipated to last until March, 2010. As directed at the October 12, 2009, City Council meeting, the issues surrounding noise concerns, including the potential Briarknoll berm, Norma Avenue noise wall, and concerns along the west side of TH 10 by Round Lake, will be further discussed at the December Work Session. Following the work session, the City Council may choose to contract with Bolton & Menk, Inc. to continue investigating possible noise mitigation and complete a feasibility report. This work is included as Task 2 in the attached proposal and could be approved at a later date if desired by the City Council. Following the preliminary design and completion of the EA, Ramsey County and Mn/DOT will enter into the �nal design phase. During this time it will be important for the City to review 60% and 95% plans to ensure that comments provided to date during pre-design have been incorporated into the plans. Plans will include detailed information on the geometric layout, signal construction, construction phasing, detours, property impacts, noise wall construction. Staff feels very strongly that in order to ensure that all of the concerns brought forward during the planning process by the City Council and residents are addressed, we need the assistance of a transportation engineer. It is anticipated that preparation of final plans will take about a year to complete (April 2010 to April 201 l.) Final design support is included as Task 3 in Bolton & Menk's proposal.
