The draft EA for the proposed Master Plan Supplement evaluated potential impacts resulting
from implementation of an alternative that would reclassify 30 acres USACE-owned property at
the Appalachia Bay Recreational Area which was inadvertently omitted from the 2016 Master
Plan Revision. Pursuant to National Environmental Policy Act (NEPA) requirements, the EA also
evaluated anticipated impacts from a No Action alternative.
The proposed reclassification would change the current land use classification for the 30
acres from High Density Recreation to an Environmentally Sensitive Area classification. The
acreage consists of frequently flooded forested habitat immediately adjacent to Keystone
Reservoir. The proposed reclassification more accurately defines the management objectives
for this area, as it is limited to low impact recreational activities due to reoccurring flooding, and
considered sensitive habitat. Additionally, the proposed action would meet regional goals
associated with good stewardship of land and water resources, regional recreation goals, and
would allow for continued use and development of project lands without violating national
policies or public laws.
Comments, suggestions, and questions on the proposed repairs and additions can be
mailed to the attention of Mr. Craig Hilburn, Wildlife Biologist, 700 W. Capitol Avenue, Little
Rock, AR 72201, or emailed to: David.C.Hilburn@usace.army.mil.
