Madison County seems to encourage home-based businesses, which may have something to do with the prevailing religion in that area, but if the memorial/park isn't one of the listed businesses, the owners might need to apply for a special use permit, and that typically involves a hearing at local planning and zoning board. Those hearing take neighboring opinions into account and if the neighbors felt their neighborhood would have too much traffic, or an element that put their way/quality of life at risk, they could oppose the permit.
I don't really understand the business aspect anyway. Are they planning on charging admission? Or do they think they'll be taking in donations?
