What matters for project planning
The City of Franklin's Stormwater Management program, overseen by the Engineering Department under a state Phase II MS4 permit, manages drainage into the Harpeth River and its tributaries, while the Historic Zoning Commission reviews exterior changes within Franklin's designated historic districts near downtown and Main Street. Homeowners in or near a historic district should confirm local review requirements before exterior work, and all Franklin-area owners should verify parcel-specific drainage and flood conditions with the city before major foundation, plumbing, HVAC, or exterior work begins.

Verify the property, not just the city
Citywide context cannot establish a parcel’s flood zone, historic designation, permit requirements, soil conditions, or concealed construction. Confirm those items with the appropriate authority and selected provider before work begins.
