the infrastructure pattern is not capable of supporting a different land use, and it is not economically feasible to retrofit the infrastructure, therefore the nature of the subdivision cannot be changed, while the condition of the subdivision (if it is deteriorating) may cause people to wish that it could be changed. it can improve or deteriorate, but it cannot change what it is: ie. In my report I'm referring to a neighborhood that can change at the micro-level, ie.

To respond to the various calls for clarification, I'm specifically using this word in a report talking about the development of certain kinds of subdivisions, especially very homogenous single-family subdivisions in outer ring suburban areas. My bad! I'll still award Jasper the answer for pointing out my obvious oversight. Update: I'm embarrassed to admit I was accidentally searching the Mac's built-in thesaurus, not dictionary, when I checked to see if unadaptable was a word. So, what's the best word out there for not-able-to-change?

I'm looking for a word that is the opposite of 'adaptable.' I would like to say 'unadaptable,' but that's not a real word according to my dictionary.
