The computer support organization for the Jefferson Parish Administration is comprised of the Electronic Information Systems Department (EIS), the Management Information Systems Department (MIS), and the Geographic Information Systems Department (GIS). These departments are complemented by contract vendor firms. In a cooperative effort, they serve the Administrative and Legislative computer user community by maintaining computer hardware and software, developing software applications, and providing computer user training to Parish employees.

The MIS Department supports the financial system, the payroll system, and the utility billing system. It provides programming support for off-the-shelf applications, as well as in-house custom-written applications. MIS also provides support for all installed hardware, including network equipment, servers, PCs, terminals, printers, etc.

The GIS Department is responsible for the implementation and support of the Geographic Information System. This system contains information on parcels, buildings, streets, water lines, sewer lines, drainage lines and canals, waterways, land elevations, and political boundaries within unincorporated Jefferson Parish. The GIS Department can produce maps showing various combinations of this information. This information is available to the public for the cost of reproduction. The GIS Department can be contacted at (504) 736-6720.
