LAPLACE - Two months after Hurricane Isaac brought two to four feet of storm surge into hundreds of homes, St. John Parish residents can soon expect answers as to why.

Days after the storm, Sen. David Vitter asked the Corps of Engineers to investigate if the protection around New Orleans sent floodwater elsewhere.

Many Laplace residents think it did, since their flood maps show the parish should only flood once every 500 years.

The Louisiana Water Resources Council is conducing the independent review of the Corps' levees, and Sen. Vitter's office expects to have answers by the end of the month.
