Develop a mixed-use community on a tract of land large enough to function as a traditional small town.

Allow an alternate arrangement of dwellings to create a more compact, walkable community, lessening the need for automobile usage. More compact design will also allow building to occur on the most suitable land, preserving more environmentally sensitive land in its natural state.
