Flood Vents for Homes in Orange Beach and Ono Island: What You Need to Know

Flood protection is a critical consideration for homes in coastal areas like Orange Beach and Ono Island. To mitigate flood damage and comply with local building codes, many homeowners install hydrostatic flood vents in enclosed areas below the Base Flood Elevation (BFE) + 1-foot freeboard. This article explains what flood vents are, why they are necessary, and how they can protect your home.

What Are Flood Vents?

Flood vents, also known as hydrostatic vents, are openings installed in foundation walls or enclosures to allow water to flow freely in and out during a flood event. This prevents water pressure from building up on the structure, which can cause significant damage to the foundation or walls. By relieving this pressure, flood vents help maintain the integrity of your home’s structure, reducing the risk of catastrophic failure.

Why Are Flood Vents Required?

Homes in flood-prone areas, such as Orange Beach and Ono Island, are subject to strict building codes to ensure they can withstand flooding. According to the National Flood Insurance Program (NFIP) guidelines, homes built below the BFE must have flood vents installed. These vents must:

• Be installed on at least two different walls of the enclosed space.
• Meet a requirement of one square inch of venting per square foot of enclosed space.
• Be installed with the bottom of the vent no more than one foot above the ground.
• Allow for automatic entry and exit of floodwater without human intervention.

How Do Flood Vents Protect Your Home?

During a flood, water exerts pressure on the foundation of a home. Without proper venting, this pressure can cause walls to crack, buckle, or collapse. Flood vents work by allowing water to flow through the enclosed area, equalizing the pressure inside and outside the structure. This reduces the risk of structural damage and provides an additional layer of protection against floodwaters.

In addition to safeguarding your home, flood vents can also help lower your flood insurance premiums. By ensuring your home is compliant with flood mitigation measures, you may be eligible for reduced premiums under the NFIP.

Types of Flood Vents

There are two primary types of flood vents:

• Engineered Flood Vents: These are designed to meet specific performance standards and are typically certified by third-party organizations like the International Code Council (ICC). Engineered vents can cover larger areas with fewer vents and are often the preferred choice for new construction.
• Non-Engineered Flood Vents: These are more basic and may require more vents to cover the same area as an engineered vent. They are commonly used in retrofitting older homes but are less efficient than their engineered counterparts.

Installation Requirements

When installing flood vents in your home, there are specific guidelines to follow:

1. Number of Vents: A minimum of two flood vents must be installed on opposite walls of the enclosed area.
2. Size: The total vent area must equal at least one square inch for every square foot of enclosed space.
3. Placement: Vents must be located no more than one foot above the adjacent ground level.
4. Automatic Functionality: The vents must allow floodwaters to enter and exit automatically without the need for human intervention.

By ensuring that your home complies with these requirements, you’ll not only protect your investment but may also reduce your flood insurance costs.

The Importance of Compliance

Homes in Orange Beach and Ono Island are vulnerable to flooding, especially during hurricane season. Ensuring that your home has proper flood venting is essential for both safety and insurance compliance. Without the proper vents, your home may not meet local building codes, and you could face increased risks of flood damage, higher insurance premiums, or both.
