Florida’s Coastal Real Estate: Engineering for Sea-Level Rise

Florida’s Coastal Real Estate: Engineering for Sea-Level Rise

As the premier provider of civil engineering, structural engineering, and environmental engineering services in Florida, JRH Engineering & Environmental Services is leading the charge to future-proof coastal properties against rising seas.

With NOAA projecting 10–12 inches of sea-level rise by 2050 and $619 billion in Florida property value at risk this century, innovative engineering solutions are no longer optional – they’re essential for preserving investments and protecting communities.

The Rising Tide: Threats to Florida’s Coast

Accelerating Sea-Level Risks

• 8 inches of sea-level rise since 1950 (NOAA)

• 61% increase in flood damage costs projected over 30 years

• 7% price discounts for exposed Miami properties (Harvard Study)

Despite these risks, coastal development continues unabated, with 87% of vulnerable areas overlapping FEMA floodplains.

Regulatory Shifts Driving Change

Florida’s 2024 Building Code now mandates:

• 1-foot freeboard above Base Flood Elevation (BFE) for all homes

• 2-foot elevation for critical infrastructure

• Coastal A-Zone requirements matching V-Zone standards

Structural Engineering Solutions for Resilient Foundations

Raised Foundation Systems

JRH implements three proven strategies for coastal properties:

1. Flood-Resistant Raised Slabs

• 12+ inches above BFE with helical pile support

• Geopolymer concrete resisting 2,500 psi hydrostatic pressure

• Integrated capillary breaks preventing moisture intrusion

2. Elevated Pile Foundations

• 8–15 ft clearance for storm surge protection

• Carbon fiber-reinforced breakaway walls

• Scour-resistant footings embedded below erosion depth

3. Hybrid Coastal Systems

• Combining elevated living spaces with:

• Submerged utility cores

• Permeable ground floors

• Tidal buffer zones

Civil Engineering Strategies for Community Resilience

Stormwater Infrastructure Overhaul

Per the South Florida Water Management District’s 2024 Resiliency Plan:

• Atlas 14-compliant drainage (500-year storm capacity)

• Living shorelines replacing 40% of seawalls

• AI-powered flood sensors in critical corridors

Site-Specific Solutions

• Permeable pavements reducing runoff by 60%

• Bio-swales with salt-tolerant vegetation

• Modular pump stations for rapid water displacement

Why Licensed Structural Engineers Are Non-Negotiable

Regulatory Compliance

Florida’s Structural Engineering Recognition Program (SERP) requires engineers to demonstrate:

• 5+ years of coastal project experience

• NCEES certification for high-risk structures

• Advanced load modeling for wave forces and debris impact

Technical Expertise

Licensed engineers deliver:

• FEMA P-55 compliant foundation designs

• ASCE 7-22 wind/flood load calculations

• Scour prevention systems for vulnerable soils

Final Thought

With 1 in 3 Florida properties projected to face chronic flooding by 2050, engineering resilience is the smartest investment coastal owners can make.

As the premier provider of civil engineering, structural engineering, and environmental engineering services in Florida, JRH Engineering combines cutting-edge technology with decades of coastal expertise.

From Miami high-rises to Keys cottages, we’re engineering a future where Florida’s coastlines thrive – no matter what the tides bring.
