Development Patterns Comparison (CSD -vs- TND)

Item	Conventional Suburban Development (CSD)	Traditional Neighborhood Development (TND)
Example
Compact, Walkable Neighborhoods	Isolated “pods”, which are dedicated to single uses Sprawl and “leapfrog” developments, limited by range of automobile	Compact development Most daily life needs are within a five (5) minute walking distance from center
Transportation Choices	Uses are inaccessible from each other, except by car	Reduces automobile dependency Design is equitable for pedestrians, bikes, mass transit AND automobiles
Interconnected Streets	High Proportion of cul-de-sacs and looping streets within each pod (curvilinear) Few automobile route options designed around a hierarchy of smaller roads funneling traffic into larger roads Produces bottlenecks due to a lack of route connectivity between destination points Streets are wide and dedicated primarily to the automobile	Grid network with small block patterns (rectilinear) Provides multiple routes to and through and to any given point Increases travel path options Accommodates blocking of one of the routes due to accident Streets are narrower, giving important consideration to the pedestrian while accommodating the automobile
Pedestrian-Friendly Streets	Buildings are rotated on their lots and greatly setback from the street making it difficult to create a sense of place Parking lots dominate public spaces	Promotes walkability and human-scale design Traffic calming devices to reduce vehicular speed Planting buffers provide shelter and shade Minimizes number of driveway crossings Streets are spatially defined by a wall of buildings that front the sidewalk and are uninterrupted by parking lots
Housing Diversity	Housing is strictly segregated Housing is predominantly single family detached Low density	Housing is better integrated Multiple housing types and products (size, price & type) Residents may move through the housing preferences life cycle without leaving the community Greater density
Mixed-Use	Regulates use and assumes that all uses are incompatible, thus separating them Civic buildings are designed as an afterthought Open space is provided by buffers or berms and act as residual spaces	Eclectic mix of uses within a short distance from each other Focuses on regulating form, design and proximity of uses Buildings are diverse in function, but compatible in size and disposition Civic buildings are treated as landmarks and are placed on squares or the termination of street vistas Open space is provided by squares, playgrounds, parks and greenbelts.
