Wetland Fill Permits Florida Keys Monroe County

A wetland fill permit is one of the most complex and sensitive environmental approvals in Monroe County. The Florida Keys contain a variety of wetland and surface water types — including mangrove shorelines, transitional wetlands, buttonwood wetlands, and freshwater wetlands — all regulated at the local, state, and federal level.

Glen Boe & Associates has managed wetland fill permit applications throughout the Florida Keys since 1984. We understand the regulatory framework, the agency expectations, and the mitigation requirements that are typical for fill projects in Monroe County.

When Is a Wetland Fill Permit Required?

A permit is required any time fill material — including clean earthen fill, rock, or other material — is placed in a wetland or surface water in Florida. Common situations requiring fill permits include:

• Filling wetland areas on residential or commercial lots to create upland buildable area
• Placing fill for access roads or driveways that cross wetland areas
• Fill or grading that affects tidal wetlands
• Site preparation that involves filling low-lying areas with wetland vegetation

Agencies Involved

U.S. Army Corps of Engineers (ACOE) — Section 404 The ACOE regulates the discharge of fill material into waters of the United States under Section 404 of the Clean Water Act. Wetland fill projects require ACOE authorization, which may be provided through a Nationwide Permit for smaller, low-impact projects or an individual permit for projects with greater potential impacts.

Florida Department of Environmental Protection (FDEP) — Environmental Resource Permit FDEP issues Environmental Resource Permits for wetland fill projects in Florida. The ERP review evaluates impacts to wetland functions and values, and typically requires a mitigation plan to offset unavoidable wetland impacts.

Mitigation Requirements Wetland fill projects that cannot avoid or minimize impacts to wetland resources are typically required to provide mitigation — most commonly through the purchase of mitigation bank credits. Glen Boe & Associates identifies applicable mitigation banks, calculates mitigation requirements, and coordinates the mitigation process as part of the permit application.

Local Permits Monroe County and municipal jurisdictions may have additional requirements for fill activities. We coordinate local permitting requirements as part of our full-service approach.

Our Approach

Wetland fill applications require careful documentation of existing wetland conditions, detailed impact calculations, and a well-prepared mitigation plan. Applications that are incomplete or inadequately documented result in agency requests for additional information — adding months to the permitting timeline.

Glen Boe & Associates prepares thorough, well-documented wetland fill permit applications from the start. Our team has worked with ACOE and FDEP reviewers in the Florida Keys for over 40 years. We understand what these agencies need to see and how to present projects in a way that moves efficiently through the review process.
