Divers from NOAA and one of the project construction subcontractors, Marine Resources Inc., are working on a number of pre-construction tasks to ready the site for restoration. These mobilization activities include:

1) removal of benthic biota from the 14 restoration sites and
transplanting them to adjacent areas;

2) installation of approximately 9 mooring points on the bottom that will anchor the construction barge in place over the site;

3) establishing a mooring point in deeper water in case the barge needs to move away from the sensitive reef area during severe weather;

4) marking the perimeter of the work zone with distinctive exclusion buoys to alert the public to avoid the area for safety reasons;

5) removing recreational mooring buoys from the work zone (These will be replaced once the restoration is completed).

Weather delayed the work barge and both the installation of the mooring points and the loading of the barge in Port St. Lucie. A media and NOAA leadership site visit was scheduled for May 30th. The delay in the arrival of the work barge caused cancellation of the media componet of the trip. The media visit has been rescheduled for June 25th. NOAA's new General Council, James Walpole was given a tour of the Wellwood restoration site.

The final step of mobilization, the “test pour” of tremie concrete, was conducted May 31 by Underwater Engineering Services, Inc. The "test pour" took place on the storm anchorage location away from Molasses Reef to determine if there were any concrete mix or turbidity issues.

An Underwater Engineering Services Inc. diver is sent down to correctly place the concrete mixing tub on the bottom. This precautionary practice insures there is no damage to fragile marine resources and that the tub settles in a level position for the test pour of tremie concrete.
