But there weren't enough of these neighborhoods to supply the demand. A new alternative to suburbia was needed. The new Traditional Neighborhood Developments are an effort to recapture that neighborhood spirit for the families of today. In many ways they resemble the earlier neighborhoods, with tree-lined streets, sidewalks, and front porches. Streets are laid out in grid patterns, allowing a variety of routes between any two points.
Lots are narrow, allowing the houses to be built closer together, increasing density.
And the porches are pulled close to the street. Not only does this allow for casual interaction between pedestrians and people on the porches, but it also allows more space in the rear for private gardens and garages. Traditional Neighborhood Developments are designed to accommodate the automobile. Unlike many suburbs, in TNDs the garages are tucked in back, accessible from alleys or lanes, as they often were in the earlier neighborhoods. In a true TND, you won't see gaping garage doors lining the streets.
