I read the article below recently:
Are historic districts necessary?
I have dealt with this issue myself and feel that the designation of a locale as a historic district does tend to be rather abritary and subject to the whims of the times. I think that top-down government imposed historic districts (ones where the property owners are told they will be in one) should not exist. If we are to have historic districts, then it should be initiated by 100% of the property owners, though, in general, I am against historic districts.
What are your thoughts?
