Construction of detention pond set for November
LAFAYETTE — A $5 million drainage project to address long-running flooding issues in Carencro is set to begin in November, the results of a search for solutions that dates back to the 1990s.
The U.S. Army Corps of Engineers project involves building a large retention pond to hold back water during heavy rains and clearing and digging out of about 2 miles of the Beau Bassin Coulee that runs through the city.
“It’s almost 20 years that they have been looking at it,” Carencro Mayor Glenn Brasseaux said.
The mayor said Beau Bassin Coulee drains about 80 percent of the city.
In November, crews are set be begin building the retention pond, which is expected to be complete by April, according to information from the corps.
The contract for the second phase — clearing and digging out the coulee — is expected to be awarded early next year, according to the corps.
Brasseaux said the retention pond will help, but clearing out the coulee will have the biggest impact.
Lafayette city-parish government has a related project to clear out the Beau Bassin Coulee for another half-mile outside the city limits of Carencro.
Carencro and the surrounding rural areas have had ongoing flooding problems.
More than 400 homes took on water during the last major flood in the area, in March 2012.
Brasseaux said some of that flooding would have happened regardless of how well Beau Bassin Coulee drained, because the rain came too fast — more than 10 inches in the just a few hours.
“Even if it had been cleared out, you still would have had flooding,” he said.
Brasseaux said the coulee project would make a similar flooding event less severe and should go a long way toward addressing the more routine flooding that can happen after just a few inches of rain.
Carencro has put up about $1.8 million for the $5 million project.
