3/11/2016: The U.S. Army Corps of Engineers, St. Louis
District proposes to construct the Boston Bar Bi-Op Project as part of its commitment to comply with
Endangered Species Act requirements as part of our operation of the Regulating
Works Project. The proposed action
includes the removal of three existing dikes, notching an existing pile dike, construction
of a new side channel enhancement dike (SCED), and creation of sandbar habitat
adjacent to Boston Bar using dredge disposal material from future channel
maintenance dredging that would occur within the immediate vicinity. Fill
material would include approximately 2,114 cubic yards of quarry run limestone
consisting of graded “A” stone for the new SCED and the removal of over 58,000
cubic yards of rock for removal and notching of the existing dikes. Boston Bar is located along the left descending bank of the
Middle Mississippi River between River Miles 7.6 and 10.2, in Alexander County,
Illinois, approximately 1.5 miles northwest of Cairo, Illinois, and 22.5 miles
southeast of Cape Girardeau, Missouri.
Expiration date:
