Marine permit basics
Florida marine permitting is really several reviews happening at once. Understanding how the pieces fit together — and why projects get delayed — is the best way to plan a waterfront project with fewer surprises.
The layers of review
Most waterfront projects touch more than one level of government. A single dock can involve all three of these at the same time.
Local & county
Cities and counties review the structural, zoning and land-development aspects of a project and issue the local building permit. Coastal counties may add shoreline-specific rules.
State
State review looks at environmental impacts (often through the Environmental Resource Permit program) and, where a structure sits over state-owned submerged lands, authorization to use those lands.
Federal
Federal review can apply to work in or over navigable waters and near sensitive habitat, commonly handled through a programmatic general permit for qualifying projects.

Why permits get delayed
Delays are rarely about the project being unacceptable — more often they come from avoidable gaps in the submittal. These are the causes we see most often.
Applications that arrive missing a survey, a resource assessment or a required drawing usually cannot begin substantive review until the gap is filled.
When dimensions on the survey, site plan and elevations do not match, reviewers ask for clarification before proceeding.
Seagrass, habitat and submerged-resource information is frequently required, and its absence is a common reason a project stalls.
Encroachments on riparian lines or setbacks from neighboring properties often need to be resolved before approval.
Because several agencies review in parallel, a change requested by one can ripple into resubmittals to the others.
Corrections & resubmissions
When a reviewing agency finds something missing or unclear, it typically issues a request for additional information or corrections. The project does not move forward until the applicant responds and the agency accepts the response — and that back-and-forth can happen with more than one agency.
Each round of agency corrections and resubmissions adds calendar time, even when the underlying fix is small. Because several agencies may be reviewing at once, one change can trigger updates to multiple submittals. That is why getting a complete, internally consistent package in front of reviewers the first time matters so much.
You cannot eliminate review — agencies are going to look carefully at work in and over the water. But you can reduce the number of avoidable correction cycles by anticipating what each reviewer needs before you submit.
How Tideway helps
Tideway is a marine-permitting platform. It uses historical permitting data and TideAI to help identify likely requirements and common problems earlier, keep a project organized across agencies, and prepare submissions that are less likely to come back for avoidable corrections. It does not decide applications — agencies do — and it never guarantees an outcome or a timeline.
