Florida Greenbook Chapter 19: Traditional Neighborhood Development (TND)

In May of 2011, Florida Department of Transportation revised their Manual of Uniform Minimum Standards for Design, Construction and Maintenance for Streets and Highways. The document, commonly referred to as the Florida Greenbook, contains a wealth of innovative updates that address the needs and safety of all users. However, Chapter 19 stands out as especially ground breaking. The Chapter entitled Traditional Neighborhood Development takes a context sensitive approach to transportation and land use. With a focus on network functionality and design standards supporting a livable community, this is a model for 21st Century transportation.

In addition, FDOT crafted the Traditional Neighborhood Development Handbook to supplement Chapter 19 and to provide best practices to facilitate proper design of TND communities. While Chapter 19 of the Florida Greenbook has regulatory authority for use in design of TND’s, the Handbook is intended to be more instructional to those who have not designed these types of developments. A fundamental principle in designing TND is to be guided by the context of the built environment established or desired for a portion of the communities, as TND communities rely on a stronger integration of land use and transportation than seen in Conventional Suburban Development (CSD)communities. The Handbook provides guidance for planning and designing greenfield (new), brownfield or urban infill, and redevelopment projects within the compact urban context. It also clearly differentiates between CSD and TND communities to maximize the possibility that proper design criteria are used to create well executed TND communities. This is important, as the street geometry, adjacent land use, and other elements must support a higher level of transit, pedestrian, and bicycle activity than seen in a CSD.

Chapter 19 Introduction:

Florida is a national leader in planning, design and construction of Traditional Neighborhood Development (TND) communities, and in the renovation of downtown neighborhoods and business districts. These represent patterns of development aligned with the state's growth management, smart growth and sprawl containment goals. This approach, with its greater focus on pedestrian, bicycle and transit mobility; is distinct from Conventional Suburban Development (CSD). CSDs are comprised largely of subdivision and commercial strip development. TND communities rely on a strong integration of land use and transportation. A TND has clearly defined characteristics and design features that are necessary to achieve the goals for compact and livable development patterns reinforced by a context-sensitive transportation network. The treatment of land use, development patterns and transportation networks necessary for successful TND communities is a major departure from those same elements currently utilized in other Greenbook chapters.

To provide a design that accomplishes the goals set out in this chapter, designers will be guided by the context of the built environment, established or desired, for a portion of the communities because TND communities rely on a stronger integration of land use and transportation than CSD communities. This chapter provides criteria that may be used for the design of streets within a TND when such features are desired, appropriate and feasible. This involves providing a balance between mobility and livability. This chapter may be used in planning and designing new construction, urban infill, and redevelopment projects.

Section B of this chapter discusses the primary objectives of TND in more detail to aid the designer in the selection of proper criteria. Section C sets forth specific design criteria for the transportation system within TND.
