Why does the UDC include only three Historic Resource Overlays?

The new code keeps three Historic Resource Overlays—Fort Missoula, the Roosevelt Block, and the Marshall House—because these sites already had special protections and unique standards in place.

• Fort Missoula has been protected by an overlay since the 1990s and remains one of Missoula’s most important historic areas.
• The Roosevelt Block and the Marshall House were already part of special zoning districts that required historic review, so they are shown as overlays on the new map.
• These overlays help make sure any future changes respect each site’s history.
• Other historic buildings in Missoula are still protected through the Historic Preservation Permit process, even without an overlay.

In short, these three overlays were kept because they already had extra rules in place, while other historic sites remain protected in different ways.
