FEMA Mitigation Best Practices: U. S. Army Corps of Engineers Digs in to Help Carencro   [open pdf - 375KB]

This document is part of the Federal Emergency Management Agency (FEMA) Best Practices Portfolio. "The FEMA Best Practices Portfolio consists of mitigation stories submitted by individuals and communities that describe measures they have taken to reduce the loss of life and property from disasters. These Best Practices are meant to provide ideas and concepts about reducing losses and to encourage others to evaluate their own risk and consider mitigation as a long-term solution to reducing that risk." This Best Practice Story is about flood mitigation efforts in Carencro, Louisiana. "Lush, green Lafayette Parish in Louisiana is surrounded by an abundance of water from lakes, swamps, marsh basins, bayous, and other streams that require constant management. Carencro, a small suburb of Lafayette, sits on the northern tip of the Parish within the Carencro Bayou. Its excess water is drained primarily through the Coulee Beau Bassin, Lantier Coulee, the Coulee Mine (covering more than 30,000 acres) and smaller coulees through the bayou into the Vermilion River. Coulee is a French term for 'flowing' or 'running' in reference to drainage of waterways or streams. While the community is enhanced by the beauty of its natural environment, all that water plagued the more than 8,000 residents of Carencro for many years with major flooding. […] While the study's final report had found that cleaning the coulees was an absolute necessity, it would not be sufficient to alleviate the problem adequately. Ultimately it was decided that, in addition to clearing the coulees of refuse and blockage that had built up over the years, a detention pond should be constructed to hold excess water that would slowly disperse into the coulees and on to the bayou.
