Green River Levee Improvement Program
The Federal Emergency Management Agency (FEMA) de-certified all levees along the Green River in Kent. This has resulted in many property owners being required to purchase costly flood insurance. This project includes inspecting, rebuilding and improving all Green River levees as needed to protect the Kent valley from flooding. Standards varied widely when these levees were being constructed, generally during the 1930s and 1940s. The levees have protected the valley very well, and will continue to do so. However, FEMA will not accredit the levees until we provide data showing they are sound. The City's Levee Improvement Program includes:
- Conducting geotechnical inspections of all levees to identify areas needing repair
- Rebuilding any weak or substandard sections
- Removing large trees and roots that could cause damage to the levees
- Removing ivies and other ground covers that can prevent routine inspections
- Certifying the improved levees, and submitting applications to FEMA so properties are removed from the Kent valley floodplains
