Mon Louis Island Tip Restoration

With sediment analyses and watershed management plans completed and a permit received from the U. S. Army Corps of Engineers in March, the NFWF GEBF-funded restoration of the erosion-impacted northern tip of Mon Louis Island began in early July. A temporary access channel was dug on the shoreward side of the 1995 shoreline footprint, with material side cast. A 1,400-foot continuous rock breakwater was constructed from south to north as the access channel was refilled. With breakwater construction completed in early September, dredge activities commenced. Sandy material was hydraulically pumped from the Fowl River Open Water Disposal Area behind the breakwater to an elevation of +3.5 NAVD88 to create a suitable substrate for marsh creation and completed over a one-week period. In mid-September, dredges moved to the Fowl River navigation channel where maintenance dredging of the neglected and shallow channel to depths of eight to 11 feet was undertaken with funding through a State Deepwater Horizon Impact Grant to refill the FROWDA borrow pit. Dredging operations were completed in October. Final grading, planting, and tidal creek creation will be undertaken in three to six months, in late winter to spring, when placed material has consolidated.

Addressing Immediate Threats to northern Mon Louis Island – Shoreline Stabilization and Habitat Creation
Awaiting final permitting by the U. S. Army Corps of Engineers to begin the bidding process for construction, a plan has been developed by Thompson Engineering that will result in restoration of the receding shoreline and creation of approximately four acres of salt marsh habitat on northern Mon Louis Island, south of and adjacent to the mouth of East Fowl River. The first step in the process will be the construction of a rock breakwater positioned roughly along the 1995 footprint of the island. A 50 foot-wide, temporary access channel will be constructed just leeward of the breakwater footprint with material side cast on the leeward side to allow construction of the +3.1 NAVD88 breakwater using #4 riprap with 1:2 slope and seaward toe protection. As the breakwater construction progresses from south to north, the temporary channel will be replaced. When breakwater construction is complete, dredging activities will commence.

Suitable sandy material (approximately 40,000 cubic yards) will be “borrowed” from the permitted, near shore USACOE Fowl River Open Water Disposal Area and hydraulically pumped over and behind the breakwater above grade to create approximately four acres of marsh substrate.

To mitigate the depression left after borrowing, Sen. Bill Hightower identified a funding source, an Alabama Deepwater Horizon Incident Grant of $800,000 that was subsequently secured, to finance dredging of the shallow Fowl River Navigation channel. Material dredged from the channel will be beneficially used to replace material borrowed from the disposal area and avoid negative environmental impacts. In this case, only one dredge mobilization and demobilization will be necessary to accomplish marsh creation fill and channel maintenance dredging, representing significant cost savings for accomplishing both tasks.
