A case study of the development of an urban drainage master plan for Orleans Parish, Louisiana is presented. The Parish, which occupies an area of approximately 98,000 acres, lies entirely below sea level, protected by levees along the Mississippi River and Pontchartrain Lake. The existing drainage system consists of more than 227 miles of canals and culverts, and 19 major pumping stations. The preparation of the master plan was accomplished in four phases: the development of a computer model to stimulate the operation of the existing system, the selection of the planning storm, the identification of deficiencies in the existing system and formulation of alternative improvement schemes, and the selection of proposed improvements and development of an implementation program.
