Several months ago, I started doing some research on Historic Districts and Historic Overlays. It has taken some time to go through and find good, solid information that may be useful as the Town of Christiansburg Planning Commission works on the Historic Overlay project. (Am I a world-class topic hopper, or what?)
I'll warn you that this is a work in progress and that a lot of the specific links to jurisdictions with codes concerning historic districts/historic overlay districts are not ready yet. However, there are some links to good resources and some quotes from the State Code that are relevant.
Please feel free to let me know of any additional sites that you may have found or of any specific questions for which you would like for me to try to find answers.
The Historic District District and Historic Overlay links page.
You'll also notice the website has a new look and some other new pages. I keep trying to update and refine the site based upon the types of questions you offer me...so, keep those questions coming. A bored Carol is a horrible thing to see:)
