Because the final dimensions and criteria aren't adopted yet, we design to CRD's current guidance and recheck when the new rules take effect.
With about 7.7 feet between mean higher high water and mean lower low water at the Howe Street Pier gauge, a lot changes between tides. Many Brunswick lots need a long fixed walkway across the marsh to reach water deep enough at low tide, then a gangway down to a floating dock that rises and falls. Gangway length and slope have to work at dead low tide, not just at high water. Pilings need enough embedment to hold in soft marsh sediment.
Current matters too. On the East River, the Turtle River and the bigger tidal creeks, water runs hard on both the flood and the ebb. Floating docks need pilings and hardware sized for that pull, plus storm surge on top. Irma put 3 to 5 feet of water above ground along the Georgia coast. Dock pilings should be tall enough that floats don't ride off the top in a surge like that.

If your bulkhead is near the end of its life, do it first. See bulkhead replacement in Brunswick.
Marine construction in Brunswick typically costs $400–$800 per linear foot for new dock construction and $250–$600 per linear foot for new seawall or bulkhead construction. Walkway length across the marsh, piling depth and water access have the biggest effect.

The Georgia DNR Coastal Resources Division issues a Revocable License for a private dock from your own parcel. Local permits also apply.
Yes. CRD is adopting permanent private dock rules, with Board action expected in late October 2026. We design to the rules in effect when you apply.
Brunswick's tides swing about 7.7 feet a day. A floating dock stays at water level, and the gangway handles the height change.
Permitting usually takes longer than construction. Once approved, most residential docks take a few weeks, depending on walkway length.
