DRAFT 2012 Coastal Master Plan

145 Projects Totaling Approximately$50 Billion over 50 Years


40/49

A Closer Look: Southwest Coast

Restoration: Restore wetlands and chenier ridges whilelimiting saltwater intrusion. Maintain and increase, wherepossible, the input of fresh water to maintain a balanceamong saline and fresh wetlands.

Protection: Levees are proposed for the Lake Charles andAbbeville areas. Nonstructural measures are proposed forless populated areas. Restoration of chenier ridges andhealthy wetlands contribute additional storm protection.


41/49

A Closer Look: Southwest Coast


42/49

A Closer Look: Central Coast

Restoration: Maintain the land building capacity of theAtchafalaya region, while increasing the use of sedimentand water east to Terrebonne Parish to sustain the coastalecosystem. Rebuild barrier islands and ridges.

Protection: Levee protection is proposed for Morgan City,Houma, Franklin, and New Iberia. Nonstructural protectionmeasures are proposed for less populated areas.Restoration of the barrier islands, marshes, and ridgescontribute additional protection.


43/49

A Closer Look: Central Coast


44/49

A Closer Look: Southeast Coast

Restoration: Use sediment and water from the MississippiRiver to maintain and rebuild land. Sustain a diversity ofcoastal habitats including cypress swamps, marshes,ridges, and barrier islands.

Protection: Sustain key leveeprotection systems, such asGreater New Orleans area andLarose to Golden Meadow. Newlevees are proposed for larger, at

risk communities, such asLaPlace and Slidell.Nonstructural protectionmeasures are proposed for allparishes in the area.
