Hurricane and Storm Damage Risk Reduction System, Lake Pontchartrain & Vicinity - Jefferson Parish |
Official Project Name
Hurricane and Storm Damage Risk Reduction System, Lake Pontchartrain & Vicinity - Jefferson Parish
Location
Lake Pontchartrain and Vicinity (LPV) – Jefferson Parish is located the greater New Orleans area between the Mississippi River and Lake Pontchartrain in Jefferson Parish. The structural features being built by the Corps will reduce the risk associated with a storm surge that has a one percent chance of occurring in any given year, or a 100-year storm surge. The total construction value for LPV-Jefferson Parish is an estimated $500 million.
Purpose
The project is designed to reduce risk to residents within the project area. Structural features being built by the Corps will reduce the risk associated with a storm surge that has a one percent chance of occurring in any given year, or a 100-year storm surge. The total construction value for LPV-Jefferson Parish is an estimated $500 million.

Status
Prior to the 2011 hurricane season, all HSDRRS projects in Jefferson Parish had features in place to defend against the 100-year storm event; however construction at the Causeway, West Return Floodwall, and fronting protection work at Elmwood and Suburban pump stations will continue through 2012.
Benefit to the Community & Project Features
No Information at this time.
Authority
The Lake Pontchartrain, LA, and Vicinity Hurricane Protection Project (LPVHPP) was authorized by the Flood Control Act of 1965 and the Water Resources Development Acts of 1974, 1986, 1990, and 1992.
The HSDRRS includes five parishes and consists of 350 miles of levees and floodwalls; 73 non-Federal pumping stations; 3 canal closure structures with pumps; and 4 gated outlets. Following Hurricane Katrina, Congress fully authorized and funded the Hurricane and Storm Damage Risk Reduction System (HSDRRS) for southeast Louisiana.
Scope
Project features in East Jefferson include: a 3.5 mile floodwall along the Jefferson-St. Charles Parish line; 10 miles of an enlarged levee along the Jefferson Parish Lakefront including four vehicular floodgates and floodwalls connecting the four Jefferson Parish lakefront pump stations to the lakefront hurricane protection levee alignment. Also included are two breakwaters in Lake Pontchartrain at two of the lakefront pump station discharge channels.
