Hamilton Army Airfield Wetland Restoration

I found more information on the Hamilton Army Airfield Wetland Restoration project. These quotes are from the executive summary of the project.
"There are three project objectives: (1) create a diverse array of wetland and wildlife
habitats that benefit a number of threatened, endangered and other species, (2) reduce inwater disposal of dredged material and beneficially reuse dredged materials as feasible,
and (3) facilitate the base-closure and reuse process."

"Alternatives considered
1. No action
Under the No Action Plan, a Federal project would not be constructed to restore habitat in
the study area boundaries. Pumps would continue to remove runoff water from the
airfield. The environmental benefits of the proposed project would not be realized.
2. Natural Sedimentation to restore Wetlands at the Airfield and Navy Ballfields
This would result in 668 acres of habitat.  Once outboard levees are breached, tidal
sedimentation would fill the tidal portions of the project.
3. Reuse of Dredged Material to restore Wetlands at the Airfield and Navy Ballfields
This would result in 668 acres of habitat.  Dredged material would used to accelerate
marsh establishment and raise elevations for seasonal wetlands.
4. Natural Sedimentation to restore Wetlands at the Airfield, Navy Ballfields, and
SLC Property
This would result in 988 acres of habitat.  Once outboard levees are breached, tidal
sedimentation would fill the tidal portions of the project.
5. Reuse of Dredged Material to restore Wetlands at the Airfield, Navy Ballfields
and SLC Property.
This would result in 988 acres of habitat.  Dredged material would used to accelerate
marsh establishment and raise elevations for seasonal wetlands."


"Selected Plan
Alternative 5, Wetland Restoration at the Airfield, Navy Ballfields and SLC Property Via
Beneficial Reuse of Dredged Material, was selected because it creates a natural gradient
of habitats from upland through mudflat, without internal levees and water control
structures. The plan will restore 570 acres of salt marsh habitat, considered especially
valuable due to its scarcity, and benefit Federally listed threatened and endangered
species that depend on salt marsh habitat. This alternative offers the best option for
sustaining ecological functions over time and meets the habitat objective of 80 percent
tidal and 20 percent non-tidal habitats. 10.6 million cy of dredged material will be
beneficially reused to raise elevations to support the tidal and seasonal marsh restoration.
Both the Corps and the non-Federal sponsor, SCC, support Alternative 5 because it
maximizes environmental benefits and is most consistent with regional plans.
The plan includes infrastructure features, including perimeter levees, to support the
wetland habitat areas. To import dredged materials, a hydraulic off-loader mounted on a
barge would remove material from barges (scows) positioned in the off-loading area.
Dredged materials would then be transported through a pipeline in a water slurry onto the
site. The plan includes a moniring and adaptive management plan"
