Quick Answer
For flash flood evacuations, the best high ground locations are typically at least 10-15 feet above the surrounding terrain and at least 100-200 feet away from any bodies of water. Avoid areas with steep slopes that could lead to landslides or mudslides. Elevated areas with a clear path to higher ground are ideal.
Identifying High Ground Locations
When searching for high ground locations, look for areas with a consistent elevation gain of at least 10-15 feet above the surrounding terrain. This could be a natural ridge, a hill, or even a man-made structure like a bridge or an embankment. Avoid areas with loose or unstable soil, as they could lead to landslides or mudslides.
Assessing Safety and Accessibility
When evaluating a high ground location for flash flood evacuations, consider its safety and accessibility. Look for areas with a clear path to higher ground, avoiding areas with steep slopes, loose soil, or bodies of water. A safe and accessible location should have a consistent elevation gain of at least 10-15 feet above the surrounding terrain and be at least 100-200 feet away from any bodies of water.
Preparing for Flash Floods
In the event of a flash flood warning, quickly identify a high ground location and assess its safety and accessibility. Stay away from low-lying areas, such as riverbanks, streams, and low-lying valleys. Use a map or a GPS device to locate the nearest high ground location and follow a safe and clear path to reach it. If you are unable to find a safe location, stay in a sturdy building or a hard-topped vehicle with the windows closed.
