Maybe some other items of consideration:
- Nearest airport (small, county, regional, etc.) and flight routes
- Water table
- What is within 100 miles with prevailing winds (chemical/power/health, etc.) [what might be blown your way if things go badly]
- Topography with respect to if you need to bring in heavy equipment how difficult or easy will this be
- Distance in miles to nearest trauma center, followed by distance in miles to nearest emergency room
- Distance in miles to nearest town and city (what is the local population - how many potential trespassers might come your way)
- Distance in miles to nearest sheriff or highway patrol post
- Any surrounding land under control of Fed Govnmnt (wetlands etc.)
- Anything within striking distance that may flood your land
