When you build a dock over navigable or tidal water, your structure sits over water bottoms that in most states are owned by the state — held in trust for all citizens. A submerged land lease (sometimes called a "sovereign submerged land authorization," "revocable license," or "consent to use") is a formal agreement that grants you the right to use those state-owned water bottoms for your dock. It is a separate document from the environmental permit — and many homeowners are caught off guard when they discover they need both.
The Legal Concept: Public Trust Doctrine
Under the Public Trust Doctrine — a legal principle that dates back to English common law — navigable waters and their underlying lands are held by state governments in trust for the public. This means the water bottom beneath your dock in a tidal creek, navigable river, or coastal waterway isn't yours to use freely just because your property adjoins it. You're occupying state-owned land with your pilings and dock structure, and most states require formal authorization to do so.
This is why dock permitting on tidal and coastal waters almost always involves two parallel processes: an environmental permit (ensuring the construction won't harm water quality or habitat) and a submerged land authorization (granting the right to occupy the state-owned water bottom).
Florida: The Most Common Scenario
Florida is where most dock owners encounter submerged land issues. The Florida Board of Trustees of the Internal Improvement Trust Fund (effectively the state government) owns the sovereign submerged lands beneath Florida's tidal and navigable waters.
When Consent Is Automatic (No Application Needed)
For docks that qualify for the Chapter 403.813(2) state exemption — under 1,000 square feet in standard waters, under 500 in Outstanding Florida Waters — Florida automatically grants consent to use the sovereign submerged lands. No separate application is required. The exemption status effectively serves as the authorization. This is a major advantage of the exemption pathway; you're getting both environmental clearance and sovereign land consent in one determination.
When a Formal Lease Is Required
Docks that require an Environmental Resource Permit (ERP) from DEP — those too large for exemption or general permit — typically also need a formal sovereign submerged land lease from the Board of Trustees. The lease authorizes the structure to occupy state-owned bottomlands and is processed concurrently with the ERP through Florida DEP. Key lease details:
- Private residential single-family docks: Minimal annual lease fee (typically $100–$200/year for small structures) or a one-time administrative fee for qualifying docks
- Commercial or multi-slip facilities: Annual lease fees calculated based on square footage at market rates — can run thousands of dollars per year
- Duration: Typically 10-year renewable terms for residential structures
- Preemption rights: The lease documents your legal right to preempt (occupy) the specified area of state submerged lands
The 10-to-1 Preemption Rule
Florida limits how much sovereign submerged land you can preempt relative to your upland shoreline ownership. The standard rule: you may preempt up to 10 square feet of submerged land for every linear foot of shoreline you own. A property with 60 linear feet of shoreline can preempt up to 600 square feet of submerged land. This is why dock size and shoreline frontage are so interrelated in Florida permitting — the preemption rule often limits dock size below the 1,000-square-foot threshold.
Georgia: The Revocable License
Georgia calls its submerged land authorization a "Revocable License" — and as explained in the Georgia dock permit guide, this is the primary authorization document for coastal Georgia docks. It's issued by the Georgia DNR Coastal Resources Division and authorizes the licensee to occupy state-owned tidal and navigable water bottoms. The revocable nature means the state can terminate it if the holder violates conditions — but for compliant residential docks, the license is routinely renewed.
Other States With Submerged Land Requirements
| State | Document Name | Who Issues It | Notes |
|---|---|---|---|
| Florida | Sovereign Submerged Land Lease / Consent | FL Board of Trustees / DEP | Automatic for exempt docks; lease needed for ERP permits |
| Georgia | Revocable License | GA DNR Coastal Resources Division | Required for all coastal docks; bundled with CMPA permit |
| Maryland | Tidal Wetland License | Maryland Department of the Environment | Required for structures in tidal wetlands and navigable waters |
| Virginia | Permit (covers submerged land use) | Virginia Marine Resources Commission (VMRC) | VMRC joint permit application covers both environmental and submerged land review |
| South Carolina | Critical Area Permit | SC DHEC OCRM | Covers both environmental and submerged land authorization in coastal critical areas |
| Texas | Waterway Easement / General Land Office lease | TX General Land Office | Required for structures on state-owned tidal water bottoms and navigable rivers |
| Louisiana | Coastal Use Permit / Submerged Land Lease | LA Office of Coastal Management | Required in coastal zone; mineral rights complications can arise |
What Happens When You Sell a Property With a Submerged Land Lease
Submerged land leases and revocable licenses are typically tied to the property, not the individual owner. When you sell waterfront property with a leased or licensed dock, the new owner must apply to the relevant agency to transfer the lease or license. This is a standard part of waterfront property transactions in Florida, Georgia, and other states with formal submerged land programs. Transfer is typically straightforward for compliant structures — but it is not automatic, and new owners should initiate the transfer process promptly after closing.
Buyers should request copies of all submerged land lease or license documentation as part of due diligence. A dock without documented sovereign submerged land authorization in a state that requires one is a compliance issue that needs resolution before or at closing.
