When Luann Barker and her husband moved to Citrus County three years ago, they traded the beaches of South Florida for a different kind of beach outside their front door. They live in Inverness Village 4, a Citrus County neighborhood that was somehow built with no drainage system. Years of erosion have turned roads that were never paved into deeply scarred sand pits. It’s so bad that neighbors in Inverness Village 4 just lost another modern convenience: mail delivery. In a May 3 letter to neighbors, the U.S. Postal Service described the roads as impassable.
