Flood Risk Reduction Programs
Flood Protection and Floodplain Management
DEC works with communities throughout the state to find ways to reduce or protect against loss of life and property damage caused by flooding. DEC has floodplain management and protection programs that focus on:
- Structural and nonstructural flood damage reduction methods
- Sustainable floodplain management programs
- Administering local regulations and building standards for flood damage prevention in communities participating in the National Flood Insurance Program
Coastal erosion is a naturally occurring process that results in the loss or displacement of land along the coastline, which is continually changing natural protective features such as beaches, dunes, bluffs and nearshore areas.
DEC has two programs focused on the protection of coastal erosion: Coastal Erosion Hazard Area (CEHA) permit program and the United States Army Corps of Engineers (USACE) Civil Works Program. CEHA regulates and issues permits for activities within New York State's coastal erosion hazard areas. DEC also works with USACE to study coastal erosion problems along NYS coastlines and to develop coastal erosion solutions.
The Dam Safety program is responsible for regulatory dam safety inspections, technical review of proposed dam construction or modification, monitoring remedial work for compliance, monitoring owner dam safety activity, and emergency preparedness for owners and communities.
