Reducing lot sizes can help reduce the impervious surface footprint from each new home, reduce sprawl, promote walkability, and protect open space.
Less land consumption means that less infrastructure may be needed, saving the landowner money, and that the infrastructure that is installed can be used more efficiently.
As with Traditional Neighborhood Design, not everybody wants to move from crowded city neighborhoods out to crowded suburban ones.
Example 1: City of Los Angeles, CA
Description: The City of Los Angeles is trying to create more affordable housing within the city as the people have been priced out of all homes within the area.
Example 2: Spring Green, WI
Description: Zoning code allows for a classification titled Village Small Lot Residential, which allows smaller than average lots to be developed for more high density residential uses.
