Miami-Dade County permit authorities that cover Miami Beach →
- Seawall rule (City of Miami Beach (Code Ch. 54, Secs. 54-59 to 54-65); Miami-Dade DERM Class I)
- City Code Sec. 54-62 (Ord. 2021-4393, amended by Ord. 2025-4754 on 2025-07-16): all new seawalls and seawalls undergoing substantial improvement must reach 5.7 ft NAVD88; less-than-substantial repairs may stay at 4.0 ft NAVD88 only if designed for a future 5.7 ft. The city's FAQ defines a substantial repair as $300 or more per linear foot. [mbrisingabove.com]
- Dock and boat-lift permits
- City of Miami Beach Building Department + Miami-Dade DERM Class I + FDEP / USACE. Miami Beach's marine permit checklist requires DERM preliminary approval (Class I) with structural plans that locate property lines, seawall face, seawall cap and dock with their elevations, and a DERM final inspection before the building final. [miamibeachfl.gov]
- Seawall repair permits
- City of Miami Beach Building Department + Miami-Dade DERM Coastal Resources Section (Class I) + FDEP / USACE as applicable. The city FAQ lists the building-permit package (site plan, structural design, elevation certification) and states DERM Coastal Resources approval is required for seawall construction, with FDEP for state-owned bottom and a USACE Section 404 permit for any dredge or fill. [mbrisingabove.com]
- Dredging permits
- Miami-Dade DERM Class I + FDEP + USACE Jacksonville District. The city's own Biscayne Point canal dredging (to -7 ft NAVD, $6.25M) has DERM permits and FDEP exemptions in hand but was still negotiating its USACE permit as of April 2026, a real-world example of the three-agency sequence.

Local conditions that matter
Tides, storms and siltation
- About 55 miles of seawall ring the city; roughly 5 miles are public and 91% is private, so private walls are the first line of defense on the bay side and canals [mbrisingabove.com]
- King tides hit September-November and can run more than 12 inches above the year's average high tide; 2026 peaks are Oct 10 and Oct 26-27, and the city deploys temporary pump stations in the lowest neighborhoods [mbrisingabove.com]
- Hurricane Irma (2017) reduced water depths in the Biscayne Point canals enough to limit navigation, prompting a $6.25M dredging program to restore -7 ft NAVD [miamibeachfl.gov]
- The city rebuilt its public seawall along Indian Creek Drive between 41st and 29th Streets ($4.34M budget) [miamibeachfl.gov]
On the water
- Two year-round 35 mph water-ski areas sit on Meloy Channel (east side between 64th and 51st Streets, and around Monument Island between Rivo Alto and Star Islands); two more east of Meloy Channel (Indian Creek Village-Biscayne Point, and Julia Tuttle-Sunset Islands) are 35 mph only May 1-Nov 14 (MPP p. [miamidade.gov]
- FAC 68C-22.025 makes Norris Cut (between Fisher Island and Virginia Key) a year-round slow speed zone; Government Cut falls in the MacArthur Causeway-to-Miami River slow speed area [law.cornell.edu]
