Chapter 6 - Strategies for County Consideration A thoroughfare plan is ultimately a right-of-way preservation document that allows the orderly development of a transportation network to support future growth. Historically, corridor preservation and management in Florida has focused on the implementation of a major roadway system for auto and truck travel. The basis for that implementation has been the preservation and management of right-of- way needs identified for existing and planned roadways. These needs have been determined based on long range transportation demand models and reflect the functional classification of the roadway, new lanes needed to accommodate forecasted vehicular capacity needs, any adopted roadway design standards, and typical roadway cross sections. Although contemporary thoroughfare plans build on these practices, they are more context sensitive and emphasize a multimodal or complete streets philosophy. Several of the plans reviewed identify area types to guide the design of transportation corridors in relation to their planned land use context and modes. Rather than widely-spaced thoroughfares fed by disconnected local and collector roads, they promote a dense and connected network that supports multimodal activity. These and other integral strategies influence right-of-way needs and advance a more comprehensive vision of the design of the future transportation system. Contemporary thoroughfare plans serve as a preliminary tool for defining which multimodal design elements and users are prioritized for each roadway type and land use context, building on adopted multimodal plans and guidelines. The desired thoroughfare network is mapped, including area and street types, with preliminary identification of modal elements. This information is then used to define the corresponding right of way needs and cross section design concepts for purposes of corridor preservation and management. Some of the plans also provide a framework for more detailed assessment of cross section design and modal needs by segment, and guide decisions on building type and intensity to reinforce the planned modal elements. As regulatory documents, the plans also include procedures and explanations to guide amendments, exceptions and updates. With these comments in mind, this study identifies the following planning and corridor preservation strategies for consideration by the County in the update of the Hillsborough County corridor preservation plan map and corresponding plan. • Establish a clear and integrated vision of the future thoroughfare system, with flexibility and supporting technical documentation. o Consider packaging the Corridor Plan as a concise visual document referenced in the comprehensive plan that conveys vision, modal and design elements (see for example, The Indianapolis-Marion County, Fort Worth, and City of Bastrop Thoroughfare Plans). o Advance more specific corridor management and network enhancement strategies through individual Community Plans and adopt these by reference in the Corridor Plan. o Identify implementing strategies and procedures. For example, Broward County has supporting documentation for the trafficways plan map that details the implementation process, including amendments and waivers. The City of Fort Worth has a “suite” of cross section types coded to different streets and corresponding ROW widths , while allowing for “interim cross sections” for certain situations in which constructing the full cross section dictated by the Master Thoroughfare Plan would be infeasible or cost prohibitive.
