Buying land inside the blue line

I'm considerng buying a 100+ acre tract that's just within the south-side blue line so I know APA restrictions will apply but I was wondering if anyone knew off -hand if they would take issue of me creating an outdoor education center and wellness retreat. The property is APA approved for three subdivisions already which I would assume helps. Would I be free to set up a microhydro generator on the stream that runs through the property? I've never dealt with the APA but I hear how they can deny proposals more readily than outside the blue line.
