Great Rivers Habitat Alliance (GRHA) was founded in 2000 in order to directly combat the growing consumption of the 100-year Confluence Flood Plain through commercial development. Primarily comprised of St. Charles County flood plain land owners, GRHA tackles the policies permitting wholesale flood plain development and encourages thoughtful alternatives.
Since 2000, GRHA has made progress increasing the awareness of policy makers and the public about flood plain developments and levee construction efforts.
GRHA relies on support from those interested in preserving Missouri’s Big River Floodplains and Wetlands. Consider supporting GRHA by becoming a member.
