Ms. Debra Bloom, PE City of Roseville November 13, 2007 Page 2 Roadway Infrastructure Improvement Concept Layouts and Cost Development 1. Develop concept layouts for all roadway infrastructure improvements identified in the Twin Lakes AUAR Update Technical Memorandum, dated July 3, 2007. In addition, concept layouts previously developed for the future Twin Lakes Boulevard, Prior Avenue and Arthur Avenue connections will be incorporated. 2. Develop cost estimates for all roadway infrastructure improvements based on concept layouts from previous task. Incorporate potential fiber optic conduit costs into updated estimates developed in this task. 3. Prepare cost estimate documentation for inclusion in the project final report. Roadway Infrastructure Improvement Cost Allocation 1. Refine the "Traffix" models for the Twin Lakes redevelopment area, developed as part of work completed for the Tivin Lakes AUAR Update. Refinement of these models includes determining vehicular trip proportions at each intersection based on development/redevelopment assumptions. The model includes a.m. and p.m. peak hour distribution for the 14 key intersections in the project study area. Please note that this task includes determining vehicular trip proportions for two land use scenarios, scenario B and C from the Twin Lakes AUAR Update. 2. Determine the appropriate cost allocation for existing (where applicable) and proposed developments/redevelopments based on the percent of vehicles from each development/redevelopment that are identified at each intersection. Existing costs that cannot be associated with an existing development may be identified as a City/County cost. 3. Develop detailed cost-allocation matrices to display the percent breakdown by existing and future trip percentages, as well as related costs for each improvement. 4. Prepare a draft memorandum describing the study methodology, land use assumptions, and cost allocations (including the "Public Utilities Cost Allocation"). 5. Make revisions as appropriate based on City/County review and prepare final memorandum. 6. Project management and coordination, including preparation and attendance at up to two meetings with City staff and/or City Council to present findings.
