4.8 Benefits of BI restoration on longevity of system(s)<br />
With several major restoration projects in place, the post-restoration estimated YOD for several<br />
<strong>barrier</strong> <strong>isl<strong>and</strong></strong> systems in Louisiana have been extended by years to decades. This increase in<br />
<strong>isl<strong>and</strong></strong> longevity throughout the system is a direct benefit of the restoration projects. Further,<br />
with the increase in both frequency <strong>and</strong> intensity of major hurricanes over the past twelve years<br />
(<strong>and</strong> similar projections into the future), in the absence of the restoration <strong>and</strong> protection program,<br />
it is expected many of these <strong>isl<strong>and</strong></strong>s would have disappeared much sooner than original<br />
projections.<br />
5.0 Future Plans<br />
Future plans for Louisiana‟s <strong>barrier</strong> <strong>isl<strong>and</strong></strong>s include additional projects, continuation of<br />
systemwide monitoring, <strong>and</strong> the development improved management of borrow material,<br />
management of relevant sediment <strong>and</strong> geophysical data, <strong>and</strong> overall underst<strong>and</strong>ing of sediment<br />
management requirements to support the sediment needs of the <strong>Coastal</strong> Master Plan.<br />
5.1 Projects<br />
In addition to the “Future Projects” listed in Section 2, the <strong>Coastal</strong> Master Plan identifies <strong>barrier</strong><br />
<strong>isl<strong>and</strong></strong> restoration projects in four main groupings. These projects are listed as: Isles Dernieres<br />
Barrier Isl<strong>and</strong> <strong>Restoration</strong> (from Raccoon Isl<strong>and</strong> to Wine Isl<strong>and</strong>); Timbalier Isl<strong>and</strong>s Barrier<br />
Isl<strong>and</strong> <strong>Restoration</strong> (from Timbalier Isl<strong>and</strong> to Belle Pass); Belle Pass to Caminada Pass Barrier<br />
Isl<strong>and</strong> <strong>Restoration</strong>; <strong>and</strong> Barataria Pass to S<strong>and</strong>y Point Barrier Isl<strong>and</strong> <strong>Restoration</strong>. In addition to<br />
these projects, 8 of the 13 projects that Louisiana has proposed for consideration as part of<br />
NRDA Early <strong>Restoration</strong> are <strong>barrier</strong> <strong>isl<strong>and</strong></strong> projects:<br />
1) Cheniere Ronquille<br />
2) Gr<strong>and</strong> Isle Bayside Breakwaters<br />
3) West Gr<strong>and</strong> Terre Beach Nourishment<br />
4) West Gr<strong>and</strong> Terre Stabilization<br />
5) Barataria Basin Barrier Shoreline – Caminada Headl<strong>and</strong><br />
6) Caillou Lake (Whiskey Isl<strong>and</strong>)<br />
7) Ch<strong>and</strong>eleur Isl<strong>and</strong> <strong>Restoration</strong><br />
8) Shell Isl<strong>and</strong> <strong>Restoration</strong><br />
These projects will be prioritized for development <strong>and</strong> for construction in the near future.<br />
5.2 Monitoring<br />
As discussed above in Section 3.1, the BICM program has provided an extremely useful baseline<br />
of <strong>barrier</strong> <strong>isl<strong>and</strong></strong> condition. Now that we have this tremendous tool, there is a need to continue<br />
this effort to assess how the <strong>isl<strong>and</strong></strong>s continue to change over time. The CPRA will continue<br />
BICM with a second increment of data collection over the next 5 years, referred to as BICM2<br />
(Figure 14).<br />
