- MRGO was finally closed: Following the storm, in 2006, renowned Louisiana coastal scientists released a report detailing the impacts of the channel and recommending its closure. In this same year the MRGO Must Go Coalition – a group of 17 local and national NGOs and community organizations – was formed to advocate for the closure of MRGO and restoration of the ecosystem. Congress passed the Water Resources and Development Act in 2007, mandating the channel be closed to navigation and the Army Corps develop a plan for ecosystem restoration. By 2009, the channel was closed with a rock dam near Bayou La Loutre and a $1.1 billion surge barrier across the MRGO funnel was officially completed in 2013. These closures have moderated surface water salinity, setting the stage for large-scale ecosystem restoration.
- Advocacy resulting in impact: The MRGO Must Go Coalition worked closely with the Corps to watchdog the drafting of their congressionally-mandated ecosystem restoration plan. The groups helped define the size of the impact area, brought community concerns to the forefront and helped prioritize projects. The coalition, whose positions are captured in these 2010 and 2011 papers, successfully extended public comment period timelines and increased the number of scheduled public hearings. A record 75,000 public comments were sent to the Army Corps in support of MRGO Must Go recommendations. Some of the coalition’s recommendations were included in the Army Corps plan and others, notably, the Violet Diversion, were not.
- Restoration planning in earnest: In 2012, the final $3 billion Army Corps MRGO ecosystem restoration plan was approved and sent to the Assistant Secretary of the Army and a Programmatic Environmental Impact Statement was completed. Assistant Secretary Darcy then recommended $1.325 billion of projects to Congress for appropriations. This was an unusual move and speaks to strong public activism on the issue, since the Corps has no local sponsor for the MRGO project due to a dispute with the State of Louisiana about who is responsible for paying for these restoration projects. Despite strong public support and heavy activism, no wetland restoration projects in the plan have been funded by the Army Corps to date.
Around the same time in 2012, the State of Louisiana released their 2012 Coastal Master Plan, which recognized the impacts of MRGO and touted the benefits of proposed projects. The plan also reflected the important role played by the NGO community and included the vast majority of the MRGO Must Go Coalition’s ecosystem restoration recommendations, including many of those in the Army Corps’ plan.
The Master Plan projects are proving critical guides for current restoration efforts in the MRGO ecosystem restoration area – including funding from CWPPRA, RESTORE, and NRDA . It has served as a blueprint for the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) program. The Master Plan will also guide restoration work funded by the RESTORE Act, legislation that brings Clean Water Act penalties generated from the BP oil disaster, which directly impacted the MRGO ecosystem area in 2010, to the Gulf Coast for restoration.
In 2014, the state put forward three key MRGO projects – Golden Triangle Marsh Creation, Biloxi Marsh Oyster Reef Restoration and the Maurepas Diversion – as candidates for RESTORE Council funding. The MRGO Must Go Coalition advocated directly for these projects to decision-makers at the State of Louisiana and the RESTORE Council. The projects were approved by the Council in 2015 and will soon move into planning.
