The ability to live in a well-designed walkable neighborhood should be
within reach of all people, regardless of social or economic status. Affordability
is dependent on many factors, including location within a region, neighborhood
structure, access to jobs and services, and housing mix and tenure. Policy
intervention from the public sector, incentives for the private sector,
the elimination of exclusionary regulatory barriers, and participatory
planning and design will substantially increase the supply, diversity,
and quality of housing and enable new development that welcomes a diverse
mix of people.
The rural-to-urban transect is an essential tool for describing and coordinating
the human habitat. It establishes appropriate relationships between buildings,
streets, and public spaces and their natural contexts across the full range
of urban settlement --from undisturbed nature to the most intensely urban
places. The transect must be calibrated to reflect local climate, ecology,
tradition, and building practice.
Conventional use-based zoning should be replaced by design codes that guide
the creation of an enduring form for cities and towns. Such codes must
promote a mix of uses, diversity of street and housing types, and address
appropriate forms of development at all scales.
