Within an established suburban fabric, there are considerable challenges to creating affordable housing. As development standards and lot standards change over time, it is not uncommon to have irregularly shaped and nonconforming parcels that are simply not conducive to redevelopment. The City has adopted a Planned Unit Development Ordinance that permits a variety of housing types in every residential zone. The City may conditionally permit attached and detached single-family residences, town homes, patio homes, zero lot line, and any other type of housing product permitted by the regulations of the underlying zone. The PUD is a tool that has been successfully used for Town Square to encourage and facilitate innovative design, variety, and flexibility in the types of housing products, including the provision of affordable housing, that would otherwise not be allowed or possible through standards in the underlying zoning districts.
