The Issue

Cumulative Impact:
When Compliance Is Not Safety

Individual docks may comply with local code. The combined effect from both banks of the river can still create a navigational hazard that endangers vessels, blocks infrastructure access, and exposes the City to liability.

⚠
Key Principle: The New River is a federally navigable waterway. Florida law (§327.44 F.S.) explicitly prohibits any vessel or structure from unreasonably restricting the safe passage of another vessel, regardless of local permit compliance.

The Geometry Problem

The City of Fort Lauderdale measures dock extension compliance from upland property lines. A property on the north bank may extend 30% into the channel and comply with City code. A property on the south bank, under Town of Davie jurisdiction, may do the same. Together, they have consumed 60% of the channel width — or more — leaving a functional fairway that is insufficient for a 150-foot barge, a 200-foot yacht under tow, or an emergency response vessel to maneuver safely.

This is not the fault of any individual property owner. It is a systemic failure of a regulatory framework that was designed around property rights, not navigational physics.

GIS modeling conducted by the Marine Advisory Board (MAB) demonstrates the gap between the approximate 25% and 30% width calculated from BCPA Property Lines and the actual USACOE Channel Toe Line. The navigable water is consistently narrower than the permitted structures suggest.

"Planned growth versus geometric failure. Once the channel is functionally narrowed, it is politically and legally difficult to reverse."

The Regulatory Layers

Why Multiple Laws Apply

The New River is not governed by one authority. Each layer of regulation creates both constraints and enforcement opportunities.

🏭

Federal Law

The Rivers and Harbors Act of 1899 makes unauthorized obstruction of navigable waterways a federal violation. The USCG holds primary authority from the ICW to Marker 12 at Tarpon Bend and governs all bridge operations throughout the river.

33 U.S.C. §403; 33 U.S.C. §409
🏳

State Law

Florida Statutes §327.44 and §327.70 prohibit vessels and structures from unreasonably restricting safe passage. The State preempts most vessel rules but allows safety-based Boating Restricted Areas (BRAs) when formally documented (§327.46 F.S.). FWC has enforcement authority statewide.

§327.44; §327.46; §327.60; §327.70 F.S.
🏠

Local Code

City dock code is based on upland property line extensions (30% citywide; 33% annexed areas). Upstream of Marker 12 regulatory authority is shared by the City of Fort Lauderdale, Broward County, SFWMD, and LIWMD. The enforcement gap between Fort Lauderdale and Davie is the critical vulnerability.

ULDR 47-19.6.E; ULDR 47-39.A.1.b
The Enforcement Lever That Exists Right Now

Florida law explicitly prohibits vessels and structures from unreasonably restricting the safe passage of another vessel in a navigable waterway. This statute can be enforced by City Police and the FWC under existing authority, without waiting for new corridor designations. However, both agencies have indicated they prefer the City of Fort Lauderdale to formally define protected channel widths before intervening. The City must lead.
