Atlantic Beach is a coastal community of 13,000 people in Duval County, Florida. As the name implies, it has a beach and the nearby ocean affects every aspect of life, including the infrastructure. Atlantic Beach’s biggest subdivision, built in the early 1960s, didn’t really take that into account.
“The majority of Royal Palms’ storm sewer system (which also serves a large drainage area north of the subdivision) is corrugated metal pipe (CMP),” says Public Works Director Rick Carper, “and the salt, tidal influence, and sandy soil have caused major problems, like leaks, corrosion, subsidence, and even collapses.” In fact, the city was shocked that it had spent $200,000 on spot repairs, with no end in sight. So, Atlantic Beach embarked on a $3.2 million storm sewer rehabilitation project.
