Hurricane Prep for Bonita Springs Waterfront Homes
On the Imperial River and the canals off it, the water can arrive from two directions — off the bay, and down the river from rain that fell miles inland.

- Two water risks
- Coastal surge, and the river rising from inland rain
- Sheet flow
- Runoff from rain that fell miles upstream, not the tide
- Who calls evacuations
- Lee County, using its Zone A / Zone B system
- Mobile and manufactured homes
- Evacuate as part of the same county order
- First, always
- People leave. Nothing on the dock is worth staying for.
Key takeaways
- Bonita's storm-water story has two halves: surge off the bay, and the Imperial River and its canals rising from rain that fell inland.
- The city has told residents near the river and its canals to watch water levels during storms — that is sheet flow, and it has nothing to do with the tide.
- Evacuation orders here come from Lee County using its Zone A and Zone B system. Know your zone in the spring, not during a watch.
- Mobile and manufactured homes evacuate as part of the same county order.
- The structural work that decides how a dock behaves happens months before a forecast. The last two days are for securing, not fixing.
Storm prep in Bonita Springs has a shape that most of this coast does not share. Here, the water can arrive from two directions.
There is the coastal half everyone expects — a bay system on your west side and the weather that pushes water into it. And there is the half that catches newcomers: the Imperial River and the canals off it can rise because of rain that fell miles inland, hours or days before or after the wind matters at all. Both belong in your plan, and only one of them is on the tide chart.
Which water are you actually watching?
Both, and they behave differently.
The City of Bonita Springs has publicly told residents living near the Imperial River and its canals to monitor water levels during storms because of sheet flow — inland rainfall runoff working its way downstream — as something distinct from coastal storm surge. That is a genuinely local instruction, and it is the single most useful thing on this page.
The practical difference is timing and direction. Surge is a coastal event tied to the storm’s approach. Sheet flow is a watershed event: rain falls east of you, the ground gives it up, the river and the canals carry it, and levels can keep climbing after the sky has cleared and the neighbors are already out with chainsaws. A dock, a lift and a seawall that came through the wind fine can still spend a day and a half underwater.
What that changes for an owner is mostly attention span. The all-clear on the wind is not the all-clear on the water. Keep watching levels, keep the dock circuits off, and do not assume that because the storm has moved on, your waterline has peaked.
Who tells you to leave, and when?
Lee County, and earlier than you would like.
Evacuation orders covering Bonita Springs come from the county’s emergency management using the Zone A / Zone B system — a county-wide scheme, not a city-specific one. Mobile and manufactured homes are typically ordered out as part of the same call. Find out which zone your address is in during the spring, when it is a two-minute question, rather than during a watch when it is a stressful one.
Everything about the waterfront has to be finished before you leave, not squeezed in alongside leaving. When you’re told to evacuate is deliberately blunt about the order of priority: people go, property stays. There is no version of this where someone walks back down to the dock.
If you are not here year-round, that math changes again — someone local has to be able to physically reach your property on short notice. Remote storm prep for seasonal owners covers arranging it before it is needed.
What has to happen long before any forecast?
The structural half, which is the half that decides how the day goes.
A dock with sound pilings, tight connections and healthy cables, and a seawall with clear weep holes and no cracks working through the cap, behaves nothing like one that was already tired. Whatever was already loose is where it comes apart. That is not a sales line — it is how load travels.
Spring is when that work happens. Hurricane prep for docks, lifts and seawalls is the full structural list, and our Bonita Springs dock and lift repair page covers the failure patterns worth looking for on this water specifically.
What do the last few days look like?
Securing, not fixing. In this order:
- Gear off the dock. Dock box contents, ladder, chairs, fenders, rod holders, anything on a rack. Whatever leaves your dock arrives at somebody else’s, or sits on the bottom of the canal for months.
- The boat decision, already made. Where it goes was settled in the spring, including whether the US 41 bridge allows it to go anywhere at all.
- Power off at the breaker, and left off.
- Photographs. Every structure, dated, before anything happens to it. That five minutes is worth more to a claim than anything you will do afterward.
- A call to your neighbors, particularly the seasonal ones whose docks are unattended.
The seventy-two-hour watch list and the twenty-four-hour warning list are the sequenced versions.
What does coming back look like?
Slow, in daylight, and with the water still on your mind.
Dock and lift electrical stays dead until a licensed electrician has looked at it — post-storm electrical safety explains why that rule is absolute around saltwater and large metal structures. The river and canals will be carrying debris you cannot see, so going out because you can is not a reason to. Canal debris after a storm covers what is genuinely dangerous and who clears what. On wildlife, manatees included, check FWC’s guidance and idle carefully.
Then look at the structures without loading them. Treat the seawall as the quiet one: what a storm does to it mostly happens below the waterline or behind the wall, and it surfaces later as settling ground in the yard. Post-storm dock triage and the rest of the Storm Center carry the full recovery sequence.
Rebuild work is permitted through the City of Bonita Springs, with state and federal approvals where they apply — our Bonita Springs dock permits guide covers that path. Insurance treats a dock, a lift and a seawall differently from the house more often than owners expect. Read the policy and talk to your agent now, while it is quiet.
Bonita’s plan comes down to three decisions, all better made in May: what happens to the boat, who handles the property if you are away, and which zone you are in.
