• Classify all thoroughfares by function, area type or context, and modal accommodations. o Broward County has “Context Sensitive Corridors” depicted on their thoroughfare plan which are highlighted in green on the map and fall into one of three categories: Urban Core, Urban Main Street, or Urban Residential. These corridors are tied to Specific Plans that govern ROW. o The Fort Worth, Texas Thoroughfare Plan depicts “Street Types” by evaluating the streets’ respective land-use contexts and the various transportation modes needing to use each street. The five “Street Types” are Activity Streets, Commerce/Mixed-Use Streets, Neighborhood Connectors Commercial Connectors, and System Links. o The Indianapolis-Marion County Thoroughfare Plan map depicts “Context Areas” labeled as either compact or metropolitan. These disparate geographical areas are used to apply different standards including ROW. The plan incorporates right-of-way needs for all modes, providing design guidance on multi-modal facilities, and providing guidance on conflicting modal priorities (also Greenways as special corridor designations). o The El Paso Thoroughfare Plan identifies areas as compact urban or drivable suburban to differentiate thoroughfare design intentions. o Montgomery County, Maryland defines pedestrian priority areas and transit corridors and defines target speed by road classification and area type. • Adapt the thoroughfare plan to an idealized grid and include supporting network concepts. o NCHRP Report 917 provides a process for adapting a large, planned thoroughfare network to an ideal grid and prioritizing new corridors for preservation. o Indian River includes a “Extended Roadway Grid Network” in their thoroughfare plan as logical extensions of roadways to undeveloped portions of the county. The county enforces a Subdivision Collector Map to ensure that proposed development extends subdivision collector roadways to landlocked parcels. o El Paso, Texas, extends its arterial and collector grid using dashed lines on the thoroughfare plan map. o Alachua County incorporated numerous new corridors and connections in an effort to relieve congested and constrained corridors by providing alternative parallel corridors, and improve accessibility to town centers or activity centers. Issues considered included spacing standards to develop more of a grid network. o The Bastrop, Texas Thoroughfare Plan includes a well-connected grid network that establishes a long-range vision for a highly connected, multimodal street system throughout the City of Bastrop, including the local street network. It may be an interesting model for use in more location specific strategies relative to compact urban areas. o Identify opportunities for complete streets projects and transit corridors to connect to greenways and multiuse trails. Clearly designate greenways and multiuse trails as transportation, not recreational, facilities. For example, Indianapolis-Marion County includes Greenways as special corridor designations. o Update and assign the County access classifications to County arterial and collector roadways to reinforce the thoroughfare plan. Integrate multimodal and context sensitive features, such as alleys and block spacing in urban contexts and safe, continuous access to transit stops. o Implement street network connectivity in urban contexts. See Alachua County and Leon County for additional helpful examples of network connectivity provisions.
