Resiliency Project
State and local mitigation strategies to address road and stream crossing
vulnerability to inundation, erosion, and deposition-related damage.
Identify and prioritize both pre- and post-disaster projects.

Vermont Emergency Relief and Assistance Fund Incentives
Incentives for River Corridor
and Floodplain Protection
1. Support river and
floodplain data collection
2. Assist with planning
and implementation
3. Increase State and Fed
cost share and grants to
municipalities to adopt
river corridor and
floodplain protections
4. Link disaster recovery
cost share funding to
municipal protections
