Understanding the Miami Beach Seawall Ordinance: Resiliency Standards for Tidal Flood Protection

The City of Miami Beach has taken a significant step in addressing the challenges of tidal flooding and sea-level rise with the adoption of its groundbreaking seawall ordinance, known as the Resiliency Standards for Tidal Flood Protection. This ordinance sets a precedent for coastal resilience by mandating minimum construction standards for seawalls and other tidal flood barriers, ensuring they meet the demands of today and the future.

What Does the Miami Beach Seawall Ordinance Require?

Under this ordinance, property owners must adhere to specific requirements for new and existing seawalls:

1. Minimum Elevations:

   • New seawalls must be constructed to a minimum elevation of 5.7 feet NAVD 88.

   • If designed to allow future elevation increases, an initial height of 4 feet NAVD 88 is permitted, provided it can later be raised to meet the standard.
     
     

2. Upgrading Existing Seawalls:

   • Seawalls in disrepair or contributing to flooding must be brought into compliance within 730 days of notice.

   • This includes addressing structural deficiencies and ensuring that tidal waters do not flow onto neighboring properties or public spaces.
     
     

3. Penalties for Non-Compliance:

   • Property owners face fines of $250 per day for a first offense and $500 per day for subsequent offenses.
     
     

4. Permitting and Construction Standards:

   • Upgrades or replacements require approval from entities like the U.S. Army Corps of Engineers, Miami-Dade County, and the City of Miami Beach​​.
     
     

Why Is This Ordinance Important?

With over 53 miles of seawalls, of which 92% are privately owned, Miami Beach relies heavily on the collaboration of property owners to combat the growing risks of sea-level rise and tidal flooding. This ordinance is part of a broader effort to create a unified defense against these challenges:

• Preventing Flood Trespass: Consistent seawall heights help minimize the risk of water intrusion during high tides and storms.
  
  

• Future-Proofing Infrastructure: By requiring designs that accommodate future height increases, the ordinance ensures Miami Beach's flood barriers remain effective for decades​.
  
  

How Does This Affect Property Owners?

If you own a property in Miami Beach with a seawall, it’s essential to take action to comply with the new standards:

1. Assess Your Current Seawall:

   • Determine its elevation and condition by getting a Seawall Inspection. Non-compliance could result in penalties or mandatory upgrades.
     
     

2. Plan for Upgrades:

   • Budget for repairs or replacements that meet the ordinance’s requirements. Souffront Contractors Inc., a leader in seawall construction, offers expert services to help property owners navigate these upgrades efficiently.
     
     

3. Secure Permits and Compliance:

   • Permitting involves multiple agencies and adherence to stringent guidelines. Hiring an experienced contractor can streamline this process.
     
     

A Practical Tip for Property Owners

When planning to upgrade or replace a seawall, consider installing features like drainage systems or living shoreline elements. These additions improve durability, manage hydrostatic pressure, and can even enhance local ecosystems while complying with the ordinance​​.

Frequently Asked Question

What happens if my seawall is already compliant with the current standards?

If your seawall meets the minimum elevation of 5.7 feet NAVD 88 and is in good repair, you won't need to take immediate action. However, regular maintenance is essential to ensure continued compliance and effectiveness against future challenges​.

Miami Beach’s seawall ordinance is a vital measure for safeguarding the community against the impacts of climate change. By adhering to these standards, property owners can protect their investments while contributing to a more resilient coastal environment.
