Functionally-Related Complexes and the NPS

A developer taking on a project involving a group of buildings that served together historically is likely to visit an arcane corner of NPS world called the functionally-related complex policy. Military bases, hospital complexes, industrial complexes, and many other groups of buildings all come under the umbrella of what NPS regulations define as a single resource AND if a single developer or related developers takes on a phased project involving two or more buildings in the group, then the project will be required to file a single Part 1, 2 and 3 application, and will not receive a Part 3 approval until all phases are complete.
