Army Corps of Engineers, Huntington District
Burgess & Niple (B&N) was retained by the U.S. Army Corps of Engineers (USACE), Huntington District, to inventory, evaluate, and develop mitigation alternatives for aquatic and terrestrial resources potentially impacted by proposed lock extensions at the Greenup Locks and Dam on the Ohio River near Greenup, Kentucky. Preliminary analyses under the USACE’s Ohio River Main Stem Study identified the Greenup Locks and Dam as a high priority for capacity upgrades. B&N carried out these tasks in support of an Environmental Impact Statement (EIS) for the proposed lock extensions at Greenup and the J. T. Myers Locks and Dam.
The study area encompassed 166 acres of USACE property and approximately 2.5 miles of the Ohio River. Aquatic inventories included aquatic habitat delineation,electrofishing and mussel surveys. Terrestrial investigations included cover type delineation, plant inventories, and live sampling of birds and small mammal populations. Habitat Evaluation Procedure (HEP) protocols were used to quantify baseline and projected habitat values for each of the proposed project alternatives.
Aquatic mitigation alternatives proposed by B&N included construction of submerged rock dikes, protected shallows, and near bank cover structures. Terrestrial mitigation strategies included reforestation of areas impacted by dredge spoils, restoration of open field areas using native grasses and forbs, and riverbank restoration using bioengineering techniques.
