Georgia regulators had weighed whether to let private dock walkways stretch as long as 1,500 feet across the state's protected tidal marshes — roughly the length of Tybee Island's famous pier — in a rule change that drew heavy pushback from coastal residents and environmental groups. The proposal would also have allowed a variance of up to 150 additional feet to reach open water, marking a major jump from Georgia's 1,000-foot limit on private docks. On Tuesday, October 27, the DNR board amended the proposal to retain the 1,000-foot restriction and allow greater width.
The Georgia Department of Natural Resources’ Coastal Resources Division put the proposed rules up for public notice on Aug. 26, according to the agency’s own notice of proposed rules. Under the original plan, a single fixed walkway could run up to 1,500 feet long and six feet wide, with the department empowered to grant a variance of up to 150 feet beyond that — ten percent of the standard length — so a dock could reach the nearest qualifying waterway. New docks would have to terminate at the first waterway at least 20 feet wide at mean high water, per the same filing. On Tuesday, October 27, the DNR board amended the proposal to retain the 1,000-foot restriction and allow greater width.
Georgia’s current cap on private dock length is 1,000 feet, according to The Atlanta Journal-Constitution. The proposed rules would also formally allow privately owned docks to cross state-owned marshlands to link waterfront homes and other upland properties to deep-water rivers and creeks, the newspaper reported.
Why the Rule Change Is Happening Now
The push to rewrite Georgia’s dock standards traces back to a federal permitting gap. The Army Corps of Engineers’ Programmatic General Permit for private docks expired in July 2022 and was never renewed, according to the Coastal Resources Division’s public notice, which pushed the state to build its own regulatory framework from scratch. The division describes the effort as formalizing standards for private recreational docks over state-owned tidal water bottoms by updating DNR rule Subject 391-2-1, per the agency’s own rulemaking page.
That process included a lengthy stakeholder phase. The division convened a stakeholder committee that met in facilitated discussions from July 2024 through May 2025, the agency’s notice states, after pausing its rulemaking in response to earlier public input. On Tuesday, October 27, the Board of Natural Resources amended the proposal to retain the 1,000-foot restriction and allow greater width.
Public Comments Ran Heavily Against Bigger Docks
Opposition to the larger dock dimensions has been loud and well documented. The Current analyzed 103 unique public comments the Coastal Resources Division received and found that 84 opposed an earlier proposed standard of 1,000-foot-long, six-foot-wide docks as too large, according to The Current. DNR Coastal Management Chief Jill Andrews told the outlet that most commenters were concerned specifically about increasing the overall size of the fixed walkways.
The scale of what regulators originally proposed only sharpened those concerns. A 1,500-foot walkway six feet wide would cover roughly 9,000 square feet, the same outlet calculated — far beyond what neighboring states allow. South Carolina caps private dock walkways at 1,000 feet including all structures and limits them to four feet wide, while Florida restricts total private-dock area, including the walkway and end platform, to 2,000 square feet, according to the Georgia Conservancy.
Scale Comparisons Put the Length in Perspective
To grasp just how long 1,500 feet is, the AJC pointed to a few local landmarks: Tybee Pier extends 1,490 feet into the Atlantic Ocean, while Bank of America Plaza in Atlanta stands 1,023 feet tall. The Current separately noted that the main span of the Savannah River Bridge measures 1,100 feet — shorter than the originally proposed dock length.
Marsh Health Concerns Underpin the Opposition
Beyond sheer size, environmental researchers have raised concerns about what docks do to the marsh ecosystems beneath them. Underground biomass has declined across 72% of Georgia’s coastal marsh since 2014, according to research cited by Savannah Now. A decade-long series of studies found that docks cut marsh plant stem density in half and reduced marsh biomass by a third, the outlet reported — findings that have fueled pushback against any expansion of dock footprints over the tidal wetlands.
The rules under consideration would also establish a formal process for issuing revocable licenses covering the construction, reconstruction, modification and maintenance of qualifying private docks over state-owned tidal water bottoms, according to the Coastal Resources Division’s notice. The framework would apply to qualifying private docks over state-owned tidal water bottoms.
