Ridge Restoration

Breton Ridge Restoration: Bayou Terre aux Boeufs

  • Project TypeRidge Restoration
  • Project BasinBreton-Chandeleur Basin

Breton Ridge Restoration includes the restoration of two historic ridges on either side of the Mississippi River Gulf Outlet (MRGO), Bayou Terre aux Boeufs and Bayou la Loutre.

Bayou Terre aux Boeufs stretches from Delacroix to Black Bay and has historically helped buffer storm surges for St. Bernard and Plaquemines parish communities and provided critical habitat for migratory birds and other wildlife. Severe erosion around the ridge and adjacent marsh has resulted in a loss and narrowing of the ridge. Subsidence of the ridge and saltwater intrusion has killed most of the trees on the ridge. This restoration will raise the ridge to an elevation of five feet to provide coastal upland habitat, restore natural hydrology, and provide wave and storm surge attenuation.
