This property is currently R12. It is easier to develop in R12 (more density). Rex Galloway wants to rezone the property so he can put horses on it.
There is no guarantee that it will be rezoned to a lesser density. It really depends on what is happening in that vicinty. In this case, I think that planning should to keep it the same, because there is development in the area. It is a good piece of property for a quality residential development (which is what I would do, if it were mine).
Surprisingly enough, when an area like this is residential in nature, some neighbors will fight against horses. The reason being is that R-15 allows for 2 horses per acre. In this case, that could be up to 36 horses. Not saying that this will be the case, but the zoning allows for it, and the county has to plan for current and future uses as well.
All that being said, it really could go either way in this case. This property is just on the edge and I don't think most of the neighbors in that triangle would have a problem with the rezoning.
