NEW ORLEANS - In backyards across the city, pools sit unmaintained, serving as breeding grounds for mosquitoes, and posing health and safety threats to children. By law, pools shall be maintained in a clean and sanitary condition, in good repair with a functioning filtration system, and completely surrounded by a six-foot high fence with gates that are self-closing and self-latching. There are at least 61 unmaintained pools, by the city's count, and many have languished in disrepair for over a decade while owners work the city's code enforcement adjudication process to their advantage.
