If you own a home in Southport, Oak Island, St. James, Boiling Spring Lakes, or anywhere else near the mouth of the Cape Fear River, there’s a small but useful change coming next week. Starting Monday, Nov. 2, 2026, the emergency planning zones around the Brunswick Nuclear Plant in Southport are being redrawn, and your property’s zone number may change.
The news came in a joint public notice posted Oct. 26, 2026 by Brunswick County, New Hanover County, North Carolina Emergency Management, and Duke Energy, and was also covered by WECT on Oct. 26 and WWAY. Here’s what’s changing, what isn’t, and what it means if you’re buying, selling, or settling into a home in this part of the coast.
What’s Changing on Nov. 2
The Emergency Planning Zone, or EPZ, is the area of roughly 10 miles in every direction around the plant. It takes in specific parts of Brunswick and New Hanover counties. Inside that area, properties are assigned to smaller numbered zones so officials can give clear, targeted instructions if they’re ever needed.
According to the county’s notice, three things are happening:
- The map grows from 13 zones to 20. Because the area is being divided more finely, many properties may end up with a different zone number than they had before.
- Several zone boundaries are moving. Even if you’re used to knowing your zone, it’s worth checking again.
- Duke Energy’s interactive map updates Nov. 2. You’ll be able to type in an address at Duke Energy’s Brunswick Nuclear Plant preparedness page (duke-energy.com/NuclearEP) and see both the zone number and the designated relocation center for that property.
What isn’t changing
The overall size of the EPZ stays the same. No new neighborhoods are being added to the 10-mile area, and none are being dropped. This is a reorganization of the zones inside it, not an expansion.
Why the Zones Are Being Redrawn
The notice says local and state emergency management and radiological professionals spent the past two years reviewing the zones to account for population changes, new developments, and road capacity. If you’ve driven N.C. 211 or N.C. 133 lately, that won’t surprise you. Southeastern Brunswick County has added a lot of rooftops, and the communities between Southport, Boiling Spring Lakes, and Oak Island look very different than they did a decade ago.
More zones mean officials can match instructions to how people actually live and travel today, which should make any protective actions or evacuations more orderly if they’re ever necessary. The county and Duke Energy describe a nuclear emergency as unlikely, and this update is part of routine planning, not a response to any problem at the plant.
What This Means for Homeowners
For most owners, this is a five-minute task. Starting Nov. 2:
- Look up your home’s new zone on Duke Energy’s map, and note your relocation center.
- Check the other places your family spends time, like work, school, and a parent’s or grandparent’s house. The map works for any address.
- Watch your mailbox. Duke Energy mails a postcard to every property inside the EPZ each year, and this year’s arrives in early November with the new zone information.
- Update your family plan. If you keep a hurricane kit or a written evacuation plan, add your zone number to it. The same habits that get you ready for storm season, like a go-bag and a plan for pets, cover this too.
It also helps to know how alerts work. Duke Energy notes that outdoor sirens are the primary warning system and that regularly scheduled siren tests happen on Wednesdays. A siren doesn’t mean leave. It means turn on local radio or TV for instructions from officials.
What This Means for Buyers and Relocators
We work with a lot of buyers moving to Southport, Oak Island, and St. James from out of state, and the plant is a common question. Here’s how we suggest thinking about it:
- It’s one more piece of local knowledge, like a flood zone. When you tour a home in southeastern Brunswick County, look up its EPZ zone the same way you’d look up its flood zone or its distance to the nearest grocery store.
- Know your routes. The zone review focused partly on road capacity. Look at how a neighborhood connects to main roads, which matters for daily commuting as much as emergencies.
- Ask about community readiness. Many HOAs and towns in this area share preparedness information with residents. It’s a fair question to ask during your due diligence.
What This Means for Sellers
There’s nothing sellers need to do because of this change, and it doesn’t alter the property itself. But buyers from outside the area do ask. Having your home’s new zone number and a copy of the annual Duke Energy postcard on hand shows you’re a prepared, informed owner, and it answers the question before it becomes a worry.
Frequently Asked Questions
Is the emergency planning area getting bigger?
No. According to Brunswick County’s Oct. 26 notice, the size of the 10-mile EPZ isn’t changing. Only the zone boundaries and numbering inside it are.
When can I find my new zone number?
Starting Monday, Nov. 2, 2026, on Duke Energy’s interactive map at duke-energy.com/NuclearEP. Properties in the EPZ will also get a postcard in early November.
Does this affect New Hanover County?
Yes, in part. The EPZ covers specific parts of both Brunswick and New Hanover counties, which is why New Hanover County was part of the joint announcement. If you live near the southern end of Pleasure Island, check your address too.
Who do I contact with questions?
The notice directs residents to their county’s emergency management department. You can find contact details on the Brunswick County notice.
Thinking About a Move to Southport or Oak Island?
Southeastern Brunswick County is one of the most popular parts of the Cape Fear coast, and the details that matter here, from zones and flood maps to HOA rules and commute routes, are the kind of local knowledge we bring to every search. If you’re buying, selling, or just want to understand a neighborhood better, reach out to Aspyre Collective and we’ll help you sort it out.
