Connecting CRS and Habitat Conservation
CRS was created to encourage flood loss prevention and reduction activities in communities. Those goals are also advanced by promoting natural floodplain functions. As a result, the CRS recently expanded its credits to include such floodplain protection activities. The CRS’s system of credit points now recognizes the tremendous value of the natural areas that border the nation’s rivers, lakes, and oceans. FEMA recognizes that protecting natural functions also helps prevent and reduce flood losses.
Specific CRS Credits That May Be Used to Protect Habitat
The CRS Credit for Habitat Protection guidance is designed for local officials and others who work with the NFIP and apply its floodplain construction standards, but may not be familiar with the CRS and its benefits or with the ESA and its requirements. The guidebook reviews the many good floodplain management practices that can protect habitat and help reduce and prevent flood damage.
Three types of activities are listed here along with the relevant section in the CRS Coordinator’s Manual and other useful references.
1. Public information activities
2. Mapping, Regulations and Open Space Preservation Activities
3. Restoration activities
1. Public information activities
CRS 300 Series

2. Mapping, Regulations and Open Space Preservation Activities
MAPPING

PRESERVATION
- Preserving open space in floodplains [Activity 420 (Open Space Preservation), Section 422.a. Also see the NOAA Mapping CRS Open Space tutorial and Nature Conservancy CRS Explorer]
