The following two types of alternative subdivision designs would require a Planned Unit Development (PUD):Conservation Subdivisions: Wholly or in majority, a residential subdivision that permits a reduction in lot area, setback, or other site development regulations, provided 1) there is no increase in the overall density permitted for a conventional subdivision in a given zoning district, and 2) the remaining land area is used for common space.
Traditional Neighborhood District (TND) Subdivisions: Allow the development of urban neighborhoods that produce new development consistent with the patterns of historic or traditional parts of Storm Lake with appropriate civic space; or provide for the recreation of neighborhoods that follow the patterns of other traditional towns.
