cycle 1

The Sabine Refuge Marsh Creation Cycle I project is intended to strategically create marsh in large, open water areas to block wind-induced saltwater introduction and freshwater loss. In addition, CS-28-1 will increase nourishment in adjacent marshes while reducing open water fetch (distance a wave can travel) and the erosion of marsh fringe.

Cycle I constructed 214 acres of marsh within the shallow, open water area within retention dikes.  The perimeter of the created marsh was planted with smooth cordgrass.  Dredged slurry obtained from the Army Corps of Engineers’ dredging of the Calcasieu River Ship Channel was placed in the containment area.

Upon consolidation of the dredged material, the southern containment dike was degraded and breached to allow for water movement, and to restore the area to more natural conditions.  Prior to the placement of the dredged material, trenasses (small, man-made bayous) were constructed in the project area.  These trenasses facilitate natural conditions and allow estuarine organisms to access the created marsh.  This project is part of five cycles over a 10-year period, with each cycle requiring individual construction approval.


The Sabine Refuge Marsh Creation Project is located in the Sabine National Wildlife Refuge, west of LA Highway 27, in large, open water areas north and northwest of Brown’s Lake in Cameron Parish, Louisiana.

Priority Project List 8 funded $5.9 million to complete construction of a permanent pipeline and one cycle of marsh creation.  Engineering analyses at the time indicated that the construction of a temporary pipeline would be more cost effective.  Therefore, a temporary pipeline was utilized for Cycle I.  However, further analysis determined that a permanent pipeline would be advantageous.  In 2004, additional funds for engineering and design, and construction were approved for Cycles II and III.  Funds for Cycle II include the construction of a permanent dredged material pipeline.

Construction of the Cycle I site was completed on February 26, 2002.

This project is on Priority Project List 8.

The Sabine Refuge Marsh Creation Cycle I’s three sponsors include:

  • Federal Sponsor: U.S. Army Corps of Engineers
  • Federal Sponsor: U.S. Fish and Wildlife Service

Aerial View One

Substantial areas of interior emergent marsh on Marsh Island have been converted to open water, primarily because of Hurricane Lili (2002).  Areas targeted under this project are those with the greatest historical land loss and within close proximity to East Cote Blanche Bay.

This project is designed to re-create brackish marsh habitat in the open water areas of the interior marsh primarily caused by hurricane damage.  Based on 2007 aerial photography analysis, approximately 197 acres of marsh will be nourished and 165 acres of open water will be restored to interior emergent marsh habitat.  The loss rates for the interior ponded areas are estimated to be reduced by 50 percent.  This project provides a synergistic effect with CWPPRA’s Marsh Island Hydrologic Restoration (TV-14), a project constructed in December 2001.


This project is located in the Teche/Vermilion Basin at the east end of Marsh Island Wildlife Refuge southeast of Lake Sand in Iberia Parish, Louisiana.

The Louisiana Coastal Wetlands Conservation and Restoration Task Force approved funding for Engineering and Design at their February 2005 meeting.  The U.S. Environmental Protection Agency and the Natural Resources Conservation Service, working through the Louisiana Department of Natural Resources, completed the Engineering and Design of this project, and construction began in March 2010.

Prior to implementation of the Coastwide Nutria Control Program in 2002, fur trapping activity had declined drastically for over 10 years because of weak market demand and low prices.  In coastal Louisiana, this decline has resulted in overpopulation of nutria and serious damage to coastal wetlands from nutria herbivory.  Mature nutria are very prolific, leading to a high population.  Without significant annual harvest, nutria can cause significant damage to marshes and swamps in coastal Louisiana.  Annual aerial surveys from 1993 to 2001 have indicated that approximately 100,000 acres have been impacted coastwide.

This project’s objective is to significantly reduce the damage nutria herbivory causes to coastal wetlands.  The Coastwide Nutria Control Program is designed to remove about 400,000 nutria annually.  The control program consists of an incentive payment program to encourage nutria harvesting.  Nutria harvest locations are recorded in an effort to compare harvest levels and occurrence of herbivory damage.  The program is implemented by the Louisiana Department of Wildlife and Fisheries.

Project Area

This project is located throughout the coastal zone of Louisiana.  The program area includes all basins and coastal parishes located south of Interstates 10 and 12.

The Coastwide Nutria Control Program was selected for Phrase 1 (engineering and design) funding at the January 2002 Louisiana Coastal Wetlands Conservation and Restoration Task Force meeting (Priority List 11).  Phase 2 (implementation) was approved during the April 2002 Task Force meeting and began in November 2002 with the 2002-03 Louisiana trapping season.  Over the first eight years of program implementation, nutria harvest has averaged 321,354 per year.  Acres damaged by herbivory has decreased from about 100,000 acres to about 8,500 acres since the program began.  The approved funding for this project is $36.7 M with a total estimated cost of $68.0 M.

This project is on Priority Project List 11.

The Coastwide Nutria Control Program’s two sponsors include:

  • Federal Sponsor: Natural Resources Conservation Service
  • Local Sponsor: Coastal Protection and Restoration Authority

Louisiana Smart Growth Summit 2015


Program Book

CWPPRA learns about a more liveable Louisiana

The Center for Planning Excellence, also known as CPEX, is a non-profit organization with a centrally focused mission of creating a more livable Louisiana by innovation of planning, policies, and community evolution.  CPEX’s primary efforts include coordinating and creating highly functional communities which incorporate the local cultural personality of urban, rural, and regional areas.  CPEX, founded in 2006, has participated in more than 20 Louisiana cities, towns, and parish planning efforts; while having leveraged over $5.5 million from communities statewide.  The Center for Planning Excellence hosted its 10th Louisiana Smart Growth Summit at the Shaw Center for the Arts on November 3rd and 4th in Baton Rouge, Louisiana.

The CWPPRA public outreach staff had the opportunity to further learn about planning, leadership, and development trends pertaining to issues regarding Louisiana’s future.  Anthony Foxx, Secretary of the United States Department of Transportation and 2015 keynote speaker, delivered highly insightful theories on the most beneficial methods of travel for both humans, as well as the surrounding environment.  In addition to Anthony Foxx, CPEX also hosted more than 50 other speakers and panelists including headline speakers such as Chris Leinberger, President of Locus; Peter Calthorpe, Principal of Calthorpe Associates;  Rons Sims, former Deputy Secretary of U.S. Department of Housing and Urban Development; Chuck Marohn, President of Strong Towns; and John Fregonese, President of Fregonese Associates, Inc.  While the utilization of technology toward smart development is significant, manipulating a community and its natural environment to reach the maximum potential of convenience, health, and safety is the ultimate goal.

CWPPRA strives to continue fulfilling projects which offer the most beneficial results to Louisiana, while logically assessing methods of least environment disturbance.

CWPPRA introduces “Sid the Restoration Squid”

The CWPPRA public outreach staff attended the LSU-LA Sea Grant event, Ocean Commotion, on October 27th, 2015 at the LSU Pete Maravich Assembly Center in Baton Rouge, Louisiana.  Ocean Commotion is an interactive, educational experience in which approximately 2,200 local K-8 students, teachers, and chaperons are able to learn the significance of the coastal regions, as well as the ocean in which Louisiana so heavily relies upon.  This event creates a connection between students and the coast by providing the opportunity to become “hands-on” with activities that generate relativity, interests, and curiosity in Louisiana’s passive shoreline environments.  In order for future generations to effectively protect our oceans, coastlines, and wetlands, learning about the importance and benefits of each is essential to continued health and survival.

CWPPRA was among the 71 exhibitors present and eager to provide a positive and impactful learning experience.  To accurately portray the importance of aquatic, coastal regions, the CWPPRA staff utilized an ocean character, Sid the Restoration Squid, whose six unique legs represented a different restoration method.  The six restoration methods presented include barrier island restorations, marsh creations, shoreline protection, hydrologic restoration, freshwater and sediment diversions, and terracing.  Each leg consisted of a distinct craft material that would correspond with a restoration method, in which students would assemble and personalize their own squid.  Each student’s personal squid was accompanied by an explanation guide of CWPPRA’s efforts to restore, protect, and/or create Louisiana’s wetlands.

World Wetlands Day 2014



HOUMA, La. – Monday, February 3rd was World Wetlands Day at the Bayou Terrebonne Waterlife Museum. The day was filled with activities for students in grades 3-6, teaching them about different functions and values of wetlands in Louisiana. The Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) Public Outreach team attended the event.

The primary focus of CWPPRA’s activity was to teach the students about the variety of wetland habitats and how each is important to Louisiana. Students learned about swamps, marshes, and barrier islands as well as techniques used by CWPPRA to preserve these areas.

Students participated in an activity called “Where the Wild Things Belong,” where the goal was to place the bean bag depicting a native species to Louisiana in the correct habitat. Approximately 240 students attended the Waterlife Museum throughout the day.
