This division is responsible for the maintenance of all subsurface drainage within the city. This is essential in minimizing / eliminating street flooding. One of the problems relating to street ponding can be attributed to debris, such as leaves, grass, silt, and other objects flowing or deposited into catch basins in most areas. Maintenance consists of flushing pipes, clearing drains of debris on a regular basis, and repairing or replacing drains and drain lines on an as-needed basis to improve flow. This division also installs new drains (as need be) in an effort to alleviate flooding in problem areas. Maintenance of drainage canals and pump stations falls under the jurisdiction of the Jefferson Parish Drainage Department.
