The St. Johns River Water Management District Governing Board agreed to split the cost of an $8 million lagoon study with the U.S. Army Corps of Engineers. The study will take five years and is designed to conclude with a list of improvements the groups would ask Congress to pay for starting in 2008. This could mean hundreds of millions of dollars for the lagoon in the future. The project is one part of the larger Everglades restoration that is planned to restore waterways and wetlands throughout Central and South Florida that were damaged in the past by Corps Construction Projects.
