I am currently working on a neighborhood revitalization project which includes new sidewalks, curbs, street trees, and pedestrian scale lighting. We plan on removing all the sidewalks and re-grading the area, and using concrete to repave the whole section. But there are a few (limited) sections of slate sidewalks, which are not in all that great of condition now, and the historic preservation specialist and a few home owners in the area are in an up-rise about this. Does anyone have any suggestions on how to get them on board, or a compromise (such as having the home owner pay for the resetting of the slate after it is graded). Any help would be appreciated.
