I have been working with another planner in our office on adopting design standards for single-family homes in our City. The standards include no "snout" garages, requiring windows on all elevations, and requiring compatibility for infill housing with its surrounding environment.
The two ordinances we have prepared (one for older infill districts, and one for newer "greenfield" subdivision areas) have been sent to the homebuilders in town for their input. As expected, everyone is in an uproar saying they will lose all of their home plans if they can't build snout garages, etc. The question that has arisen from more than one person is if this change is being proposed for aesthetic purposes only. We'd like to know if anyone out there can point us to any studies that show how these standards, either negatively or positively affect property values or do anything more than just improve the aesthetics of a community. As a planner, I feel aesthetics are enough of a reason, but we can't sell that to the development community or the Common Council that has to adopt these ordinances.
