Marine Permitting in Marathon, FL | Glen Boe Associates

Getting a dock permit in Marathon FL requires coordination with multiple federal, state, and local agencies — and Glen Boe Associates has been managing that process here since 1984, with 1,566 completed projects in the City of Marathon alone.

Whether your property sits on a canal, Florida Bay, Boot Key Harbor, or the Atlantic Ocean side, Glen Boe & Associates manages every permit your waterfront project requires — completely in-house.

We design and permit every type of waterfront structure for Marathon residential and commercial properties:

• Dock Design & Permitting — Fixed dock design by our licensed PE, with full ACOE, FDEP, and FKNMS permit management.
• Seawall Design & Permitting — Seawall repair, replacement, and new construction for Marathon canal and open-water properties.
• Maintenance Dredging — Dredging plans, benthic surveys by our FKNMS-approved biologist, and full ACOE and FDEP permit applications.
• Boat Lifts & Davits — Design and permitting for boat lifts, davits, and boat ramps throughout Marathon.
• Wetland Fill Permitting — Full Environmental Resource Permit management for fill projects in Marathon and surrounding Monroe County.
• Benthic Surveys — Conducted in-house by our FKNMS-authorized biologist for Marathon nearshore construction projects.
• Swim & Observation Platforms — Design and permitting for residential waterfront properties throughout the Marathon area.

Marathon waterfront projects require permits from multiple agencies. As a City of Marathon property owner, your project will typically require coordination with:

• U.S. Army Corps of Engineers (ACOE) — Authorization under Section 10 of the Rivers and Harbors Act and/or Section 404 of the Clean Water Act. Depending on project scope, this may be a Nationwide Permit verification or an individual permit application.
• Florida Department of Environmental Protection (FDEP) — An Environmental Resource Permit is required for dock, seawall, dredging, and fill construction in Florida’s coastal waters and wetlands.
• Florida Keys National Marine Sanctuary (FKNMS) — Projects with potential impacts to coral or benthic resources require FKNMS coordination. Our FKNMS-approved biologist conducts any required surveys in-house.
• City of Marathon Building Department — All waterfront construction in the City of Marathon requires a local building permit. Glen Boe Associates designs all projects to meet City of Marathon building code requirements and provides your contractor with all federal and state approvals to support the local permit application.
