Rep. Bost Discusses Flow Frequency Study Impacts on Flood Insurance and Levee Systems

Concerns Over Flow Frequency Study Impacts

• ⚠️ Rep. Mike Bost expresses significant concerns from constituents regarding the potential impact of a flow frequency study on flood insurance and levee certification.
• 💡 His district in southern Illinois is protected by three NAGO waterways, making levee systems critically important for safeguarding farmlands, homes, and communities.

Economic Impacts on Agriculture

• 🚜 The study's potential to affect the 50-year flood accreditation for agricultural levee districts could lead to substantial financial losses, estimated at $1 to $2,000 per acre.
• 💰 This translates to a potential loss of $15 to $30 million per acre for agricultural regions, impacting an already struggling industry.

Urban Area Flood Protection

• 🏙️ For urban areas like the Metro East, losing 500-year accreditation could result in a 20-30% drop in property values, amounting to $3.6 to $5.4 billion.
• 🏢 This impacts critical infrastructure, including major interstates and refineries, and protects approximately 150,000 people and $18 billion in property values.

Symbiotic Relationship: Navigation and Flood Control

• 🚢 Navigation improvements and flood control are described as a symbiotic relationship, working together to maintain usable waterways.
• 🌊 Structures like revetments and dikes protect levees from scour, while levees prevent rivers from flooding extensively, ensuring the channel remains functional.

Funding Challenges for Levee Maintenance

• 📉 A potential loss in property values due to the study could decrease the property tax base, reducing funds available for levee maintenance and operation.
• 🛠️ This financial strain could compromise the safety and effectiveness of levee systems, as districts rely on these funds for ongoing upkeep and repairs.
