The Zoning Law That Outlasted Its Own Preservation Status
Historic designation protects buildings, not the zoning logic that gives them meaning—a distinction with real consequences for urban planning.
Church Square in Columbus, Georgia demonstrates a critical gap in preservation policy: National Register listings protect structures but not the zoning rules that created them. The 1828 survey that designated this block for churches is legally more vulnerable than the 1980 historic designation that recognized its buildings. As federal preservation funding retreated under Reagan-era policy shifts, cities learned that a protected building sitting inside an unprotected zoning system can still be rewritten tomorrow.
On December 2, 1980, Church Square in Columbus, Georgia entered the National Register of Historic Places. That same year, Ronald Reagan's New Federalism was already reshaping how Washington thought about preservation funding. The timing is not coincidental. It is the whole point. Edward Lloyd Thomas drew his survey lines in 1828 and designated that block for churches. First Baptist Church of Columbus and St. Luke United Methodist Church still stand there, bounded by 2nd and 3rd Avenues, 11th and 12th Streets. The buildings are listed. The decision that made them is not. Most people assume that a National Register listing locks something in. It does not. The NRHP tells you a property has historical significance. It does not prevent demolition. It does not override a zoning board. It does not freeze the underlying regulatory logic that gave the place its character in the first place. The zoning law that created Church Square is 156 years older than its preservation status, and it is legally more fragile. This is the gap that catches practitioners off guard. Preservation law and zoning law do not evolve together. They do not even speak the same language. One protects buildings. The other governs land use. When they diverge, you get exactly this: a protected structure sitting inside a system that could still be rewritten tomorrow. Reagan's 1980 policy shift was the moment federal preservation philosophy started pulling back from the commitments it had built through the 1960s and 1970s. The National Register was listing properties at the same time the funding architecture underneath it was weakening. Church Square arrived on the Register already shadowed by that reversal. The building got its recognition. The rule that made the building meaningful did not. For anyone working with legacy land-use decisions, this is the practical takeaway. A historic designation is not a zoning immune system. It protects the artifact, not the logic that produced the artifact. And in a city where a single surveyor's judgment from 1828 still shapes what can and cannot be built on a downtown block, that distinction matters every time a variance request crosses a board's desk.
