Floodplain Zoning Explained: Diagrams, Sketches and Examples for Geography

📚 Quick Study Guide

• 🌍 Definition: Floodplain zoning is a land use management tool used to restrict or permit development in areas prone to flooding.
• 🌊 Purpose: To minimize flood damage to property and protect human lives.
• 📝 Regulations: Often involves building codes, elevation requirements, and restrictions on certain types of development.
• 📊 Flood Maps: Zoning decisions are typically based on flood maps created by agencies like FEMA (in the US).
• 📐 Base Flood Elevation (BFE): The elevation to which floodwater is anticipated to rise during a base flood (100-year flood).
• 🏘️ Examples: Regulations might prohibit building new homes in high-risk zones or require existing structures to be elevated.
• 💡 Benefits: Reduces flood insurance costs, protects the environment, and promotes sustainable development.
