Drainage & Stormwater for St. Augustine Beach property owners
Good drainage work in St. Augustine Beach begins with an afternoon on the property. The St. Johns County Pier and A1A Beach Boulevard both sit inside the area we cover in St. Augustine Beach. What comes across our desk from St. Augustine Beach is mostly oceanfront homes, elevated beach houses and vacation rental properties.
Two site conditions drive most of what drainage work costs here. Shifting dune sand where the Coastal Construction Control Line, not the property line, decides how far seaward anything can be built. And direct Atlantic exposure with documented erosion cycles — pilings and breakaway wall design are code requirements, not upgrades.
What coastal conditions in St. Augustine Beach change
Drainage in St. Augustine Beach works against a water table that is often only a foot or two down. Direct Atlantic exposure with documented erosion cycles — pilings and breakaway wall design are code requirements, not upgrades. That means infiltration solutions — dry wells, French drains discharging to ground — have far less capacity here than the same detail would inland, because the ground is already close to saturated. Add tidal influence on any outfall and the system has to work when the tide is high, not just when it's convenient. State CCCL permitting through Florida DEP layered on top of city and county review.
Something else that decides the scope here: older single-story beach houses being replaced with elevated construction on pilings. It changes what we expect to find once we start, and therefore what we're willing to quote before we do.
Approvals run through City of St. Augustine Beach Building Department. That gets checked on the first visit, not after plans are paid for.
What that adds up to is a drainage work approach built around St. Augustine Beach specifically: the site investigated before the design commits, materials chosen for the conditions they'll actually live in, and a schedule that reflects the real permitting timeline rather than an optimistic one.

What actually drives the cost
We won't quote a number sight unseen. These are the factors that move it, so you can see where your project is likely to land before we ever walk the property.
- Where the water can legally go
- The single biggest variable. A parcel with a ditch, easement or street inlet to discharge into is straightforward. One with nowhere to send water needs retention, and retention is volume, excavation and area.
- Surface versus subsurface
- Regrading and swales cost a fraction of a piped subsurface system. We recommend the cheaper one whenever the site will accept it, which is more often than people expect.
Working in St. Augustine Beach.
We do drainage work on St. Augustine Beach property — surface grading, tidal-aware outfalls, and getting roof and hardscape water away from foundations that are already sitting in a high-moisture environment. Oceanfront homes, elevated beach houses and vacation rental properties define the setting.
Our St. Johns County work covers St. Augustine Beach plus St. Augustine, Vilano Beach, Elkton and World Golf Village — near enough to each other that a site visit is never a production.
- oceanfront homes
- elevated beach houses
- vacation rental properties

Why doesn't a dry well work on my St. Augustine Beach lot?
Because a dry well has to have somewhere to put water, and in St. Augustine Beach the water table is frequently right there already. Direct Atlantic exposure with documented erosion cycles — pilings and breakaway wall design are code requirements, not upgrades. Infiltration systems that work fine inland underperform badly here — surface conveyance to a proper outfall is usually the honest answer.
What should I budget for drainage work in St. Augustine Beach?
It depends on the site more than on the square footage. Shifting dune sand where the Coastal Construction Control Line, not the property line, decides how far seaward anything can be built, and direct Atlantic exposure with documented erosion cycles — pilings and breakaway wall design are code requirements, not upgrades, both of which move the number materially in St. Augustine Beach. We quote after a walkthrough, free of charge.
Do I need a permit for drainage work in St. Augustine Beach?
In most cases yes, and it goes through City of St. Augustine Beach Building Department. State CCCL permitting through Florida DEP layered on top of city and county review. We pull the permits and handle the agency coordination as part of the job — you shouldn't be the one working out which office reviews what.
How soon can you start a project in St. Augustine Beach?
We can usually get out to a St. Augustine Beach property within a week for a walkthrough. Actual start dates depend on permitting through City of St. Augustine Beach Building Department more than on our calendar — we'll give you a realistic timeline for your jurisdiction rather than an optimistic one.
How far do you go from Keystone Heights — does that include St. Augustine Beach?
Yes — St. Augustine Beach is well inside the radius we work from Keystone Heights, as are St. Augustine, Vilano Beach and Elkton. Give us a call at (352) 478-6112 and we'll set up a walkthrough.
Can you stop my neighbor's water coming onto my property?
We can intercept and redirect it across your own land. What we won't do is push it back onto theirs, which trades a drainage problem for a legal one. The fix is a route that handles the flow without making it someone else's.
Will drainage work fix a wet crawlspace or slab?
Frequently, because the source is usually roof water and surface flow arriving at the foundation. Where the problem is a high water table rather than surface water, drainage helps but is not the whole answer, and we'll say so rather than sell a system that underdelivers.
