Coastal living comes with many perks—beautiful views, ocean breezes, and easy water access. But for homeowners in Edgewater and Cape St. Claire, the risk of flooding is a major concern. Heavy rains, storm surges, and rising water levels can damage homes and outdoor structures, especially decks.
A well-built, elevated deck can protect your outdoor space from flood damage, making it more durable and resilient in extreme weather. Whether you’re building a new deck or modifying an existing one, raising it above flood-prone areas is a smart investment.
Understanding Flood Risks in Coastal Maryland
Flooding in Edgewater and Cape St. Claire can happen due to heavy rain, hurricanes, or coastal storm surges. Low-lying properties near the Chesapeake Bay and its tributaries are particularly vulnerable. High tides and water runoff can quickly lead to standing water that weakens traditional deck foundations.
Local building codes often require elevated structures in flood zones. Ensuring your deck meets these guidelines not only protects your property but can also lower insurance costs.
Benefits of Raising Your Deck in Coastal Areas
- Reduces Water Damage – Elevating a deck keeps the structure above floodwaters, preventing wood rot, warping, and decay.
- Prevents Erosion – Higher decks protect the foundation from soil erosion caused by frequent flooding.
- Extends Deck Lifespan – Water-resistant materials combined with an elevated structure increase durability.
- Increases Home Value – A properly built elevated deck is a desirable feature for coastal homebuyers.
- Enhances Outdoor Views – Raising the deck offers better vantage points for enjoying waterfront scenery.
Choosing the Right Materials for a Flood-Resistant Deck
Using weather-resistant materials is essential for long-term performance.
| Material | Benefits | Considerations |
| Composite Decking | Moisture-resistant, won’t rot or warp | Higher upfront cost |
| Pressure-Treated Wood | Affordable, widely available | Requires frequent sealing and maintenance |
| PVC Decking | 100% waterproof, durable | Can be slippery when wet |
| Aluminum Decking | Rust-proof, withstands extreme weather | Expensive, industrial appearance |
| Concrete Piers | Strong foundation, resists erosion | Requires professional installation |
Key Considerations When Raising a Deck
Flood Zone Regulations
Local ordinances in Edgewater and Cape St. Claire may dictate how high decks need to be elevated. Checking with local authorities ensures compliance with FEMA guidelines and floodplain management rules.
Choosing the Right Elevation Height
The deck should be built above Base Flood Elevation (BFE). This height is determined based on historical flood data and anticipated water levels during storms.
Structural Support & Foundations
A raised deck needs a strong foundation to handle high water levels and potential storm surges. Common options include:
- Concrete piers for maximum durability.
- Helical piles for soft, sandy soil.
- Flood-resistant footing materials to prevent shifting.
Drainage & Water Flow Management
Proper drainage prevents water from pooling beneath the deck. Solutions include:
- Sloping the ground away from the deck.
- Installing French drains.
- Using permeable pavers under the deck.

FAQ: Raising Your Deck in Flood-Prone Areas
How high should my deck be to prevent flooding?
Decks should be built above Base Flood Elevation (BFE), typically at least one foot higher than projected flood levels.
Do I need a permit to raise my deck in Edgewater or Cape St. Claire?
Yes, most coastal areas require permits and inspections to ensure compliance with local floodplain regulations.
Can I elevate an existing deck, or do I need to build a new one?
In some cases, an existing deck can be lifted and reinforced. However, extensive modifications may require new construction.
What type of foundation works best for raised decks?
Concrete piers, helical piles, and reinforced footings provide the best stability against water movement and erosion.
How do I protect my deck from saltwater damage?
Use corrosion-resistant fasteners and marine-grade sealants to extend the life of your deck in a salt-air environment.
Does raising my deck increase home value?
Yes! A flood-resistant, elevated deck is an attractive feature for buyers looking for long-term protection in coastal properties.
Are composite decks better than wood for flood-prone areas?
Yes, composite and PVC decking offer superior moisture resistance compared to traditional wood options.
What maintenance is required for an elevated deck?
Regularly check for loose fasteners, inspect drainage, and apply protective coatings to prevent wear and tear.
