Specifications include, but are not limited to: A. Design and create a TDPM that will be used to analyze the impact of citywide plans, land use changes, and development projects on the City’s multimodal transportation system. a. The TDFM must establish a level of service (LOS) baseline for the existing facilities, both local and state. b. Prepare a transportation model to review level of surface standards (LOS) and project future LOS and assist in the development of concurrency standards. c. The TDFM will enable the City and outside consultants to assess the individual and cumulative traffic impacts of proposed development projects within or adjacent to the City. The City desires a model that has the capacity to analyze how development projects impact multimodal LOS [and greenhouse gas (GHG) emissions]. B. Review and synthesize material from various City and county sources including the Helena Area Long Range Transportation Plan to forecast traffic for at least twenty (20) years based on the adopted land use plans and city zoning to provide information on future growth location, timing and capacity needs. a. Identify improvement needs and recommend specific actions to bring locally owned transportation facilities into compliance with City LOS standards. b. Identify local system needs to meet future demand. c. Summarize findings and recommendations in a formal report. C. Revise traffic study guidelines in consultation with City staff. This should include an evaluation of the City’s current and proposed Traffic Impact Study (TIS) Guidelines to determine if there are any other revisions needed. D. Estimate for ongoing TDPM operations and management. a. Provide an estimate for ongoing services to operate and maintain the TDPM, with regular assessment and modifications as needed, including: training of select City staff who may assist in long-term management, conducting public and private project-level model runs and preparing analysis as needed, and staying abreast of best practices and data and updating the model accordingly. Ongoing services will be contracted separately upon completion of this project.
