FEMA Compliance & Flood Protection Guide

Last Updated: October 13, 2026

Understanding FEMA Guidelines

The Federal Emergency Management Agency (FEMA) establishes guidelines for flood protection to reduce the risk of structural damage relative to the base flood elevation (BFE). Compliance with these guidelines is essential for ensuring safety, meeting insurance requirements, and obtaining building permits in flood-prone areas.

Dry Floodproofing vs. Wet Floodproofing

Official floodplain guidance distinguishes between dry and wet floodproofing approaches:

• Dry Floodproofing: A project-specific approach intended to limit water entry below a selected protection level. Applicability depends on building use, local rules, design, and documentation; this page does not represent a Flood Barrier Pros product as certified for that purpose.
• Wet Floodproofing: Allows floodwaters to enter and exit enclosed areas (like crawlspaces or garages) to equalize hydrostatic pressure. This reduces the risk of structural failure but requires flood-resistant materials and elevating essential utilities.

FEMA Technical Bulletin 3-93

This bulletin provides technical guidance on non-residential floodproofing permits and certifications. Key requirements include:

• Design Certification: A registered design professional must certify that the floodproofing design will meet performance standards.
• Structural Integrity: Walls and barriers must be capable of resisting hydrostatic and hydrodynamic loads.
• Operations & Maintenance Plan: A documented plan must be in place to ensure barriers are deployed correctly before a flood event.

Flood Insurance Implications

Flood-insurance treatment is determined by the insurer and applicable program rules. This page does not promise a discount. Ask the insurer what documentation it will recognize before selecting a system.

• Confirm whether a registered design professional must prepare or certify project documents.
• Confirm the required property, elevation, design, permit, installation, and maintenance records.

Documents to request

Before relying on a flood barrier, request the records that apply to the selected product and project. Availability must be confirmed; this page does not assert a product certification, test result, or project approval.

Relevant records may include:

• Manufacturer specifications and test documentation.
• Installation, deployment, inspection, storage, and maintenance instructions.
• Property-specific design and permit records where required.
