You can contact Kelley Klepper through the Scott County website. I remember they did a cluster provision many years ago, when Steve Austin was there. You can contact him through Bluegrass Tomorrow. I don't think we've had much success here in Ky with clustering. Any time you try to integrate residential uses in agricultural areas, you are going to create more problems.
Agriculture always loses.
If it can be done in a more comprehensive manner, rather than just trying to cluster farm by farm, then you could get somewhere. I think Clark Countys' TDR does a more comprehensive job of just that, or would, if anybody used it. He may have some experience in clusters, or at least could tell you who does.
