Project Approach, Page 11 Project Approach - Section 3 Management Team in selecting a preferred intersection control/realignment alternative. Example categories the decision matrix may include are: Intersection operations (delay and LOS) Satisfies access spacing requirements Right-of-way impacts Minimizes private property impacts Cost We will perform a traffic signal warrant analysis to evaluate if the volumes satisfy the requirements of the MnMUTCD for the installation of a traffic signal at the major intersections listed in the RFP. The findings of forecast analysis will be incorporated into a Traffic Engineering Analysis Report. The conceptual layouts, cost estimates, and decision matrix will be included in the report. In addition, a summary of the existing conditions analysis and traffic volume forecasting will be included so documentation of all tasks are included in one report. Intersection Control Evaluations (ICE’s) will be created for intersections requiring a change in intersection control. We anticipate up to three ICE reports for this task. Phase 8 – Environmental Site Assessment Task 1 - Phase 1 Environmental Site Assessment Conduct a Phase 1 Environmental Site Assessment of the project area. Coordinate this work with the geotechnical consultant and obtain soil samples or borings near areas of known or suspected contamination. Document in the report if conditions warrant a Phase 2 Environmental Site Assessment, which would be an additional service. This work will be conducted by a sub-consultant. Phase 9 - Geometric Layout Task 1 - Geometric Layout Prepare a level 1 geometric layout depicting the proposed improvements. Depict the proposed Yale Street extension, the proposed Twin Lakes Road extension, and the proposed improvements to Highway 10. Submit to City and MnDOT for review and approval. Phase 10—Preliminary Design Task 1 – Analysis of City Needs/Site Analysis All pertinent existing information will be reviewed. We would propose at least one meeting with the City to define the project and available resources. Meet with the City to define coordination activities, obtain existing project information, review project delivery method and define special project requirements. Task 2 - 30% Design Documents Prepare preliminary design documents, including typical sections, alignments, profiles, preliminary construction limits, and drainage design. Prepare an alignment plan and tabulation with roadway centerline stationing, curve data, point numbers and control points. Depict in-place topographic survey,
