There are regulations in the development code that specify how many houses you can put into a property that has a certain amount of slope. Based on looking at it, I can guess that there is probably space for only one house (that is how badly the slope shows up when I look at the topographic maps). With that and the access issues, I find it difficult to see how this place can be developed.
As for breaking it up into parcels and then selling it to the houses surrounding it, there are several problems with that.
1) Who wants to buy land that is essentially useless because of the slope issues
2) The existing landowners surrounding the parcel already have a fairly large amount of useless slope in it.
3) Assuming that the property was able to be divided (big if), why would anyone want to increase the amount of land they have and increase their property tax basis?
I know a lot of people will look at the location and start thinking, hey, something can be done with it. It’s what we surveyors call the flat earth tendency. It looks nice now, but when you start doing the due diligence, the surveying, the engineering, it begins to lose its luster.
