Notes by domain
Water
+38Abundant rainfall and shallow wells common in eastern counties. Karst limestone in middle TN causes sinkholes & water quality issues.
Legal
+30No statewide building code for residential outside municipalities in many counties. Septic permits straightforward.
Soil
+18Generally productive; clay-heavy in spots. Perc tests usually pass.
Energy
+12Decent solar (4.5–5 sun hours), good wood-heating tradition.
Climate Risk
-8Severe storms and tornadoes are the main hazard; wildfire low.
