Heavy rain can turn Mill Creek from calm to fast-rising in a hurry. If you live or plan to buy near the creek in Nolensville, you want a clear plan that protects your home and your peace of mind. In this guide, you’ll learn how to check your property’s flood risk, harden your home, line up insurance, and tap local resources. Let’s dive in.
Know your Mill Creek risk
Mill Creek begins near Nolensville and runs roughly 28 miles to the Cumberland River, and the watershed is prone to flash and river flooding. Past events, including major flooding in May 2010 and flash flooding in September 2020, produced fast, deep water that flooded roads, yards and some homes. You can review background on the creek’s history and flood potential in this overview of Mill Creek’s watershed and notable events on Wikipedia.
For day-to-day awareness, monitor the USGS streamgage data for Mill Creek near Nolensville to see current stage and trends. The gage is a helpful, objective tool when heavy rain is in the forecast. Check the current readings on the Mill Creek near Nolensville gage page, and pair that with NWS Nashville flood advisories, which describe expected impacts at different stages.
Check your flood zone
Knowing whether your address sits in a Special Flood Hazard Area helps you plan and insure properly.
Use official maps
Start with FEMA’s Flood Map Service Center and Tennessee’s NFIP mapping resources to see the current Flood Insurance Rate Map panel for your parcel. The state’s resource page explains how to access the official map layers and find your property. Use the Tennessee NFIP mapping page to get started.
Talk to local officials
If you need a formal determination or have questions about permits, contact the Town of Nolensville’s stormwater team. They can help with drainage concerns and direct you to the right floodplain administrator for elevation certificates or permits. Start here: Town of Nolensville Stormwater Information. If you live just outside town limits, Williamson County is the local authority for unincorporated areas.
Reduce your home’s risk
Small improvements now can prevent major losses later. Focus on the items that make the biggest difference.
Elevate critical systems
Keep your HVAC units, electrical panels, and water heaters above expected flood levels. Securing fuel tanks and choosing flood-resistant materials for lower-level finishes can also reduce damage. See FEMA’s guidance on protecting your home’s systems in this summary of loss‑reduction steps: Protect your home from future flooding.
Control runoff around the house
Keep gutters and drains clear. Extend downspouts away from the foundation and ensure soil slopes away from the structure. These basics reduce pooling and help keep water out of basements and crawlspaces. Use this simple FloodSmart preparedness checklist to review routine tasks.
Add pumps and valves
A battery-backed sump pump can move water out during a power outage. Backflow valves help prevent sewage from flooding into your home during extreme rain. FEMA’s guidance above includes tips on sump pumps and backflow prevention.
Insurance and readiness
Get flood insurance early
Most homeowners insurance does not cover flood damage. If your home is in a mapped high-risk zone and you carry a mortgage through a federally regulated lender, flood insurance is usually required. Policies through the National Flood Insurance Program typically have a 30-day waiting period, so do not wait for a storm to start coverage. Learn the basics here: FEMA Flood Insurance.
Create a simple plan
Make an evacuation plan, set a meeting point, and know your safest route to higher ground. Assemble a small kit with medicines, chargers, water, snacks, pet supplies, and copies of important documents in a waterproof container. The FloodSmart checklist is a good template.
Document your home
Keep a photo or video inventory of major rooms, systems, and valuables. Store files in the cloud and keep vital documents in a waterproof pouch. If flooding occurs, photograph damage promptly for claims.
Grants and buyouts
How funding works
Federal mitigation programs like HMGP, BRIC, and FMA help pay for projects such as elevation, drainage improvements, or voluntary buyouts. Homeowners usually do not apply directly. Instead, local governments bundle interested properties into applications administered by the state. Start by understanding the programs here: FEMA Hazard Mitigation Grants.
Who to contact
If you want to explore elevation or a voluntary buyout, speak with the Town of Nolensville stormwater team first. They can advise on local processes and how to engage county or state mitigation staff if a grant cycle is open.
