Before you can apply
Permit review is the last leg of the journey. Most projects need a few professional steps completed first — these often start with Surveying, followed by Engineering and shape your overall timeline.
Surveying
2–4 weeksA licensed surveyor documents your shoreline, water depths, and property lines — the foundation every drawing is built on.
Engineering
3–4 weeksAn engineer prepares stamped plans for your dock, seawall, or lift so the design meets code and can be reviewed.
Environmental assessment
2–4 weeksSeagrass, resource, and habitat checks confirm your project protects the waterway before it reaches an agency.

What to expect
A clean, complete submission in Sumter County typically reaches a decision in about 81 days — but incomplete applications can take far longer once correction rounds start.
Most delays are avoidable: missing surveys, unsigned engineering, or overlooked agency sign-offs are the usual culprits behind requests for more information.
The Tideway platform uses historical permitting data and TideAI to help identify likely requirements and common problems earlier, so submissions are less likely to come back for avoidable corrections.
A complete, internally consistent package in front of every reviewer the first time is the best way to reduce the rounds of agency corrections that add calendar time.
