Capital projects include those major projects that reduce flooding risks and damages by increasing stormwater conveyance capacity in bayous and drainage channels, or by excavating stormwater detention basins. Stormwater detention basins reduce flooding risks and damages during heavy rain events by safely storing excess stormwater and slowly releasing it back to the bayou when the threat of flooding has passed.

Maintenance projects are repair projects aimed at returning flood damage reduction channels and other infrastructure to its designed condition by:

  • Repairing sinkholes, slope failures and other damage caused by erosion
  • Removing sediment that can reduce stormwater conveyance capacity

Smaller maintenance projects grouped together under one construction contract are often given both individual Project Identification Numbers and an umbrella number that begins with the letter “Z,” since there is often more than one watershed involved in the group. “Z-packages” have numbers such as Z100-00-00-X223.

This map does not include flood damage reduction studies or projects in other preliminary phases; smaller maintenance projects performed by Flood Control District work crews; or completed construction projects.
