We have five historic districts established in our city. For each of these districts and their surroundings, we have a historic resources survey of structures. We use this document heavily when considering Certificates of Appropriateness, district expansions, etc. There are several vacant properties that are adjacent to existing districts or in reasonable proximity.
Has anyone performed an analysis of vacant properties just outside a district for inclusion in the district? These are properties that my training in planning tells me should be in a district, but I don't have much historic preservation expertise--at least not enough for our city attorney to be totally comfortable without some back-up. If anyone could suggest some resources, articles, etc that discuss considerations for including vacant property in a historic district, I'd love those as well.
We want to create an official study of vacant properties in our city close to historic districts to justify including those properties in districts when appropriate. I don't want to be in a position where an otherwise reasonable proposal to include a vacant property in a historic district gets shot down because I don't look like an expert on paper.
