By August, Hilton Head Island homeowners should know their evacuation zone, have located the yard shutoff valve and propane cutoff, tested storm shutters or panels, and scanned key documents into cloud storage. Second-home owners managing the property from off-island need all of that done earlier, plus a named local contact holding a key.

Before August: The Resident Checklist
The prep work that actually matters happens weeks before a storm enters the five-day forecast — not the weekend it arrives. Start with the two shutoffs. Propane gets turned off at the tank itself, not just at the appliance — a call to your propane provider will walk you through the valve if you've never done it. Water is the one owners forget: the shutoff sits at the yard valve near your meter, not under the kitchen sink, and it's worth finding it in daylight now rather than searching for it by flashlight with a storm forty-eight hours out. Your Public Service District — Hilton Head has more than one, and coverage splits by neighborhood — can tell you exactly where yours is if the meter box isn't obvious.
Documents are the second piece, and the one owners consistently underestimate. Photograph or scan your deed, your homeowners and flood policies, your HOA or POA governing documents, and a room-by-room inventory of the house — furniture, art, appliances, serial numbers where you have them. Store the files somewhere reachable from a phone, not just a folder on a desktop in the house you may not be able to reach. If a claim gets filed later, the timestamp on that inventory is worth more than any receipt you'll be able to dig up after the fact.
Outdoor work rounds it out: loose branches trimmed back from the roofline, patio furniture and grills that can go airborne secured or brought in, and shutters or panels tested — not just present, tested — while there's still time to fix a stuck track or a missing bracket. The older the home, the more this matters; original hardware on a decades-old oceanfront cottage doesn't behave the same as hardware installed during a recent rebuild.
A few smaller items round out the list: a full tank of gas in any vehicle staying on the island, cash on hand since card readers and ATMs are among the first things to go down after landfall, and a portable battery bank charged and ready if you're relying on a phone for updates. None of it takes more than an afternoon, but it's an afternoon easiest to find in June, not the week a storm gets a name.
The Out-of-State Owner's Playbook
That list gets harder to execute from five hundred miles away, and this is where owners who split time off-island actually lose ground. The fix: name three people before the season starts, not during a watch.
Who holds your key. In my experience, the owners who scramble in August are the ones who never moved past a casual 'text me if anything happens' with a neighbor. A documented arrangement — a property manager or a named local contact, with clarity on who to call and what they're authorized to do, including letting a contractor into the house — is what actually holds up when the storm is real.
Who shutters the house. Book this in spring, by name, not by ad. In my experience, the reputable shutter and plywood crews on the island are booked solid within days of a storm entering the cone, and they work through their existing client list first. Calling once a storm is in the forecast means calling behind owners who booked in May.
Who documents the property afterward. Line up someone — the property manager, a trusted contractor, a neighbor you actually know — to walk the property and take dated, time-stamped photos before debris crews or landscapers clear the yard. Insurance adjusters work from what they can see; if the fence is already stacked at the curb, the claim is harder to make.
One more local detail worth knowing before you assume anything: many of the island's gated communities require architectural review before an owner installs exterior shutters or storm panels. If you're inside a POA — and in my experience, a large share of the island's higher-end communities are — check the governing documents or call the POA office before a contractor shows up with panels in hand. That's a five-minute call in May and a bad surprise in a storm watch.
Insurance and Paperwork Before the Watch Is Issued
Flood insurance through the National Flood Insurance Program carries a standard 30-day waiting period before a new policy takes effect — buying coverage once a storm has a name is already too late for that storm. If you don't currently carry flood coverage and your property sits in a flood zone, this is the one item on this list with an actual deadline attached, and it isn't in August.
Homeowners policies along the South Carolina coast typically carry a separate wind/hail deductible, calculated as a percentage of the dwelling coverage rather than a flat dollar figure — a different number than your standard deductible, worth confirming with your agent rather than assuming. Pair that conversation with a policy-number and agent-contact list kept in the same digitized folder as your document scans, so a claim doesn't start with trying to remember which agency wrote the policy.
These are the questions worth raising with your insurance agent before the season peaks, not during it.
Know Your Zone Before the Season Peaks
Everything above is preparation. What comes next is where to look when you need your zone or your route — the decision about when to act on that information belongs to the Governor's office and Beaufort County Emergency Management, communicated through the town's official alert systems.
Start with South Carolina's Know Your Zone lookup — enter your address and it returns your evacuation zone directly, using the same storm-surge modeling the state uses to issue orders. Beaufort County's zones run A through D, and the bulk of Hilton Head Island sits in Zone A, the first zone called when an evacuation is ordered — confirm your specific address rather than assuming based on your neighborhood. The SC Emergency Manager mobile app carries the same lookup for anyone who'd rather have it on a home screen than bookmarked in a browser, alongside the state's downloadable Hurricane Guide.
The town's own Hurricane FAQ and Evacuation Ready pages cover the mechanics specific to the island: six designated pickup points for residents who need evacuation transportation, the Special Call Pickup Program for anyone who can't reach one, and the two routes off the island — William Hilton Parkway and the Cross Island Parkway. Bookmark both pages now. They update faster than any guide can, and they're the source this checklist is built from — including the ongoing island infrastructure work that occasionally affects evacuation routes and timing.
Know your zone, know your route, know who holds your key — then let your agent and your Public Service District handle the specifics that don't fit in a table.

Common Questions
Frequently Asked Questions
What evacuation zone is Hilton Head Island in?
The bulk of Hilton Head Island falls in Beaufort County's Zone A, the state's highest-risk evacuation zone and typically the first zone called when an order is issued. Confirm your specific address using South Carolina's Know Your Zone lookup at scemd.org, since zone boundaries don't always match neighborhood lines exactly. Zones run A through D across the county, based on storm-surge modeling rather than distance from the coast alone.
Where is the water shutoff valve at a Hilton Head home?
The main shutoff is typically the yard valve near the water meter, not a fixture under a sink inside the house. Its exact location varies by Public Service District, since Hilton Head Island is served by more than one PSD depending on neighborhood. Locating it before hurricane season peaks avoids searching for it in the dark during a storm watch.
Should propane tanks be shut off before evacuating for a hurricane?
Yes — the shutoff happens at the tank itself, not at the appliance it feeds. A call to the propane provider will walk any homeowner through the valve location and process, and it takes only a few minutes once you know where it is. This is one of the fastest items on a pre-storm checklist and one of the most commonly skipped.
What number should Hilton Head Island residents call once an evacuation is ordered?
Hilton Head Island Fire Rescue Dispatch becomes the active line once an evacuation order is issued, at 843-682-5125. The town's Hurricane FAQ and Evacuation Ready pages carry the current, authoritative instructions for any storm in progress. This checklist covers preparation only — evacuation-specific guidance always comes from the town and Beaufort County Emergency Management directly.
How should out-of-state owners prepare a Hilton Head property for hurricane season?
Out-of-state owners need three people arranged before the season starts: a local key holder authorized to act on their behalf, a shuttering contractor booked in advance by name, and someone lined up to photograph the property immediately after landfall for insurance purposes. Reputable shuttering crews on the island are typically booked solid within days of a storm entering the five-day cone, so booking in spring matters more than any other single step. A property manager can often cover all three roles under one arrangement.
When does hurricane season peak in the Lowcountry?
Atlantic hurricane season runs June 1 through November 30, but the Lowcountry's historical peak activity falls between mid-August and October. Home-preparation tasks — shutoffs, shutters, insurance paperwork, document scanning — are best completed by the start of August, ahead of that peak window.
