The U.S. Army Corps of Engineers New York District will proceed with the restoration of two intertidal salt marsh
sites, the Joseph Medwick Park in Carteret, N.J., and the Brooklyn Union
Gas site in Staten Island
, N.Y. Both sites were selected as restoration
projects to compensate for unavoidable impacts resulting from the dredging
and deepening of the Arthur Kill Channel in the New York and New Jersey
The Corps and the Port Authority of New York and New Jersey, along with
state and local agencies, are deepening the channels in the Port as part
of an overall harbor improvement program. In addition to ensuring a safe,
efficient Port, the harbor improvement program is designed to maintain a
healthy, diverse, and sustainable environment through the creation,
enhancement, and restoration of aquatic, wetland, and upland habitat. The
program also includes the construction of artificial fishing reefs and the
capping of existing brownfields and landfills in the region.
As part of the harbor improvement program, the Corps is working in
cooperation with the Hudson-Raritan Estuary project to evaluate measures
that would address environmental degradation and other related water
resource and sediment problems and needs, including environmental
restoration and protection. The Corps is also identifying mitigation
measures for sites that may be negatively impacted by the channel
deepening. "The deepening of the harbor channels is a large scale project
that may produce unavoidable environmental impacts," Polo said. "We work
hard not only to minimize the impacts, but also to replace the habitat or
ecosystem that is affected by the deepening project
Both the Medwick Park and Brooklyn Union Gas sites involve the clearing,
excavation, and disposal of phragmites or common ferns, followed by
grading and planting of native wetland species. The goal is to restore
the environment by re-establishing tidal flow to both sites thereby
improving water and sediment quality and promoting the return of native
fish and wildlife. The restoration initiatives will also improve air
quality and ultimately improve recreational opportunities for area
The Joseph Medwick Park project information:
Removal of approximately 29,300 cubic yards of material followed by
grading and replanting of approximately 14 acres.
Removal of existing phragmites and debris, as well as the removal and
disposal of soils.
Regrading of the marsh to achieve elevations favorable to the growth of
desirable species for the site, such as various Spartina grass.
Limited placement of clean soil and the replanting of native wetland
265,000 Spartina Alterniflora bulbs in the low marsh zone
1,200 containers of Ivy Frutescens
2,000 Spartina Patens bulbs in the supratidal zone, as well as many
The Brooklyn Union Gas site project information:
Removal of approximately 32,200 cubic yards of materials and the grading
and replanting of around nine acres.
Removal of phragmites and debris, regrading the marsh surface to promote
the growth of Spartina grass, and the limited placement of clean soil.
Replanting of native wetland species on the site will include:
o 196,891 square feet of Spartina Alterniflora in the low marsh area.
o 4,175 square feet of shrubs in the high marsh area.
o 27,660 square feet of Herbaceous plants in the maritime zone, as well
as many other plantings.
The $3.3 million contract for the Joseph Medwick Park project was awarded
on Sept. 29, 2005 to the Dawson Corporation of Clarksburg, New Jersey.
The construction contract
for the Brooklyn Union Gas site was awarded on
Sept. 28, 2005 to the New York Concrete Corp in the amount of $5.3
million. Construction for both projects is expected to be completed in
the spring of 2006.
