Quick Answer
Tree platforms may not provide adequate safety from flash floods due to their elevation and exposure to heavy rainfall run-off.
Elevation and Run-off
Tree platforms, elevated above the ground, can be vulnerable to flash floodwaters that flow rapidly downhill, often exceeding the platform’s elevation. Research suggests that a 1-inch rainfall event can generate a 1-foot rise in water surface elevation. In areas with steep terrain, this can lead to a significant increase in water flow, potentially overwhelming a tree platform.
Platform Design and Construction
A well-designed tree platform can mitigate some of the risks associated with flash flooding. A platform built at least 8 feet above the ground, with a solid foundation and sturdy supports, may offer some protection. However, even a well-constructed platform can be overwhelmed by intense rainfall or rapid water flow, particularly if it is not designed to withstand the forces of water and debris.
Safety Considerations
When building or occupying a tree platform in flood-prone areas, it is essential to consider the risks of flash flooding and take necessary precautions. This includes monitoring weather forecasts, maintaining an evacuation plan, and ensuring the platform is designed and constructed to withstand the forces of water and debris.
