## Why Franklin basements take on water
Franklin sits in the Central Basin of Tennessee on Ordovician phosphatic limestone. The Maury and Mimosa soil series above it are silt over slowly permeable clay, so rain does not drain away and instead builds hydrostatic pressure against foundation walls. Water typically enters at the cove joint where the slab meets the wall. Franklin averages about 53 inches of rain a year, with May the wettest month near 6.1 inches. Karst solution channels in the limestone move groundwater sideways, which is why one house floods while a neighbor stays dry, and why Williamson County is an EPA Radon Zone 1 county. Shallow bedrock means most Franklin homes have crawl spaces or walkout daylight basements rather than full basements. The Harpeth River reaches flood stage at 30 feet at the Franklin gauge.
