Williamson County is landlocked in Middle Tennessee, so coastal rules do not apply. Development near its streams and drainageways is instead governed by open-space buffers, floodplain limits, and erosion controls protecting the Harpeth River system.
There is no coastline or tidal shoreline here; the relevant protections are river-corridor and drainageway rules. Zoning Ordinance Section 7113 requires half of any drainageway to remain open space and stay functional for drainage. Building near streams also triggers floodplain elevation standards (Section 7111) and mandatory erosion and sedimentation plans (Section 7230). Altering a stream channel, filling wetlands, or streambank work can require a federal Army Corps Section 404 permit plus a TDEC Aquatic Resource Alteration Permit (ARAP). These layered rules protect the undammed Harpeth and its tributaries.
Disturbing a protected drainageway or filling a stream without approval brings stop-work orders and restoration. Unpermitted work in state waters can draw TDEC and Army Corps penalties reaching thousands of dollars per day.
