Problem #2: Rapidly Vanishing Shoreline March 2009 January 2010 app. 150 feet of beach width (app. 100 feet of that was PUBLIC BEACH) 20 feet of beach width left (and the erosion continues) No major hurricanes during this 9-month period. Erosion this rapid has no precedent in recent history.
The Solution (Part 1): Free the Pier 1-16-1995
Proposed Project Dredge sand from PBB Fishing Pier and deposit it on the Gulf-side shoreline where public beach areas have eroded. Solves two problems simultaneously: • Removes unwanted sand from pier area • Restores the PBB fishing pier to an operative condition as a recreational fishing venue • Re-establishes lost revenue for the PBB and the Town of Dauphin Island • Restores the habitat quality of Pelican Island by eliminating foot traffic access by humans, pets and predators • Deposits desperately needed sand in crisis areas • Helps to mitigate the severe erosion affecting the most “in-crisis” areas on the Gulf-side shoreline • Initial steps toward restoring submerged public beach areas • Homes will be saved
Interim Shoreline Stabilization:Proposed Phases & Funding • Phase 1 • Dredge sand from under fishing pier, pump or dump onto eroded Gulf-side public beach areas • Finance with DIPOA-Corps settlement funds + GoMESA gas royalty funds (no taxpayer dollars) • Phase 2 • Pump/dredge sand from north shore and/or get Corps to start dumping channel-dredged sand closer to island • Finance with CIAP gas royalty funds (no taxpayer dollars) • Phase 3 • Dr. Douglass’ long-term plan (details unknown at present) • Funding source to be determined
Phase 1: Sand Source (proposed) Present Past (and Future)
Phase 2: Sand Source 1 (proposed) Some sand could be harvested from the West End north shore where massive overwash “sand fans” have land-locked private fishing and boating piers. Note that land ownership has not changed. The south shore submerged lots, in their original dimensions and locations (e.g., a 100 ft. x 100 ft. lot at a point 200 ft. south of the road) are still owned by the deed-holders, who continue to pay property taxes on the lots even though submerged. Likewise, the north shore lots retain their original deeded dimensions. The overwash sand has not legally increased the size of the north shore lots.
Diagram from the 1978 Corps of Engineers report on the effects of ship channel dredging Phase 2: Sand Source 2 (proposed) If channel-dredged sand was deposited closer to the island, sand would migrate naturally onto the beaches. This could serve as an on-going beach renourishment and maintenance program.
Restoration Phase 1 (sand from fishing pier) Restoration Phase 2 (sand from north shore and/orchannel-dredged sand dumped closer to island) Interim Solution Implementation (proposed) 2009 tide line 2004 tide line Feb 2010 tide line (approximations)
