MORGANZA TO THE GULF HURRICANE PROTECTION PROJECT
SUMMARY OF PROJECT FEATURES
COMPLETED PROJECTS:
Lower Point-aux-Chenes Hurricane Levee Reach J – Segment 1:
This project consists of a 2.8-mile levee segment, connecting to
existing TPCG (Terrebonne Parish Consolidated Government) Drainage
Levees in the Point Aux Chenes area. It was initially constructed
to a +8 foot elevation providing interim protection to the
communities of lower Terrebonne. This project was completed in
April, 2008. Immediately after Hurricane Gustav, the TLCD lifted
this levee by an additional two feet. Current elevation is
approximately +10.
CURRENT PROJECTS:
Reach H
– Segment 3 (2.8 miles):
This project consists of a 2.8 mile levee segment below Bush Canal
in the Chauvin area. It will intially be constructed to a +10 foot
elevation providing interim protection to the community of Chauvin
and the Lake Boudreaux area. This project is currently in the
construction phase with an estimated completion date of April 2009.
Lower Point-aux-Chenes Hurricane Levee Reach J – Segment 2:
This
project consists of a 5.5-mile levee section, connecting to the
floodgate on Humble Canal to the northern end of Levee Reach J –
Segment I on Bayou Pointe-aux-Chenes. This levee, as part of the
Morganza to the Gulf Hurricane Protection System will provide
protection to the communities of Montegut and lower Terrebonne.
This project is in the design phase and scheduled for construction
to commence in
March
2009.
Reach H-2 Levee: This levee reach
begins at Placid Canal and continues south parallel to Bayou Little Caillou for approximately four miles. This levee will connect Levee
Reach H-3 with the floodgate at Bayou Little Caillou. This levee
will be constructed in June, 2009 with an estimated project cost of
$15 Million.
Bush Canal Floodgate: This floodgate
will be constructed at the intersection of Bush Canal and Bayou
Terrebonne. This structure will consist of a 56’ floodgate with
three-45’ Tainter gates. This structure will connect Reach H with
Reach I, and will be constructed in December, 2009, with an
estimated cost of $40 Million.
Placid Canal Floodgate: This structure
will be built in Placid Canal between Levee Reaches H-3 and H-2,
along Bayou Little Caillou. This structure will be a 56’ floodgate,
and will provide protection to the communities of Chauvin and Dulac.
This structure will be built in December, 2009 and has an estimated
cost of $18 Million.
Bayou Pointe-aux-Chenes Floodgate: This
project is a 56’ sector gate and other associated improvements near
the intersection of Bayou Pointe-aux-Chenes and the Cut Off Canal
and will ultimately provide protection to the communities of
Pointe-aux-Chenes, Montegut and lower Terrebonne and Lafourche.
Construction of this structure will provide a closed system of
protection to the lower Pointe-aux-Chenes area. This project is in
the design phase
with the structure
construction commencing
in
December
2009.
The estimated cost of this structure is $15 Million.
Houma Navigation Canal Access Road and Bridges:
The LA DOTD is responsible for designing two replacement bridges
(Mayfield Road Bridge and DOTD’s HWY 3011 bridge) and an Access Road
for the HNC Lock. This work, once complete, will assist the Corps in
moving materials and equipment to the project site once authorized
for construction. The cost of these efforts is estimated to be $15
Million, and is scheduled to begin construction in December, 2009.
Reach J – Segment III:
This levee reach is approximately 1.3 miles in length,
beginning at Island Road, and ending at the end of Highway 665 in
Pointe-aux-Chenes, following TPCG Forced Drainage Levee 4-3B. It
will provide protection to the community of Pointe-aux-Chenes.
This levee was lifted approximately two feet under emergency
declaration immediately following Hurricane Gustav.
Reach E: This reach is approximately 3.5 miles long, and parallels Falgout
Canal from Bayou Dularge to the Houma Navigational Canal. The levee
would be just South of the parish road. The first lift will be built
to an elevation of +10.
Reach F:
This reach is approximately 3.5 miles long, and will parallel the
Houma Navigation Canal south from Falgout Canal Road to Bayou Grand
Caillou, and then from Bayou Grand Caillou to the Houma Navigational
Canal structure site. It will be built to an elevation of +10.
Reach G:
This reach is approximately 4 miles long, and proceeds east ward
from the Houma Navigation Canal Structure site. This levee generally
proceeds east until it intersects with La Hwy. 57. It follows this
highway for a short distance before terminating at levee reach H1.
The initial lift will be built to an elevation of +10.
