Building homes on the Florida coast with a 10 to 20-foot unfinished smooth surfaced concrete and stone first floor that can be easily drained and cleaned out in the event of a storm surge is theoretically possible. However, there are several factors to consider:
Building Codes and Regulations: Local building codes and regulations play a crucial role in determining the construction standards for coastal areas. These codes often include requirements for flood zones, elevation levels, and storm surge protection. It's important to consult with local authorities and adhere to their guidelines when designing and constructing such structures.
Engineering and Structural Considerations: Building a raised first floor with a significant height requires careful engineering and structural design. The foundation, support columns, and walls must be designed to withstand the forces of storm surge and potential flooding. Consulting with structural engineers experienced in coastal construction is essential to ensure the safety and integrity of the building.
Drainage Systems: Implementing an effective drainage system is crucial to quickly remove water from the first floor in the event of a storm surge. This may involve designing and installing pumps, drainage channels, and other systems to efficiently remove water and prevent damage.
Maintenance and Cleaning: While the concept of an easily cleaned and drained first floor is desirable, regular maintenance and upkeep are essential. The flooring materials must be durable and resistant to water damage, and proper cleaning and disinfection procedures should be established to ensure the area is safe and habitable after a storm surge.
Accessibility and Design Considerations: Raising the living space to higher floors means accessibility becomes a concern. Ensuring there are safe and convenient ways to access the upper floors, such as stairs or elevators, is important for residents, especially in the case of elderly or disabled individuals.
Cost Considerations: Constructing a raised, storm-surge-resistant first floor can be more expensive due to the additional engineering, materials, and construction requirements. It's important to factor in the increased costs associated with such design choices when planning a project of this nature.
It's worth noting that the feasibility and practicality of implementing this design concept would depend on several variables, including the specific location, site conditions, and individual project requirements. Consulting with architects, engineers, and local experts who specialize in coastal construction is crucial to ensure compliance with regulations and the safety of the structure in the face of storm surges.
