WASHINGTON — The green floater, a freshwater mussel native to the waters of Southern Appalachia, is now formally considered at risk of extinction due to the loss and fragmentation of its aquatic habitat. 

The U.S. Fish and Wildlife Service determined the green floater, historically found in 10 eastern U.S. states, is likely to become endangered due to existing and emerging threats. The service is proposing to list the mussel as threatened under the Endangered Species Act

The green floater is still found in its native range in North Carolina, Tennessee, Virginia and West Virginia. It is considered locally extinct in Alabama and Georgia. 

While the species has strongholds in places, green floaters are rare in nearly 80 percent of the watersheds where they naturally occur. More than 75 percent of the nation’s native freshwater mussel species are endangered or threatened, considered to be of special conservation concern, or presumed extinct, according to USWFS.

The newest road to nowhere

The former “missing link” of the Foothills Parkway. The “road to nowhere” in Bryson City, North Carolina. Blount County, Tennessee, has its own unfinished road project, without the catchy nickname: the Pellissippi Parkway Extension.This proposed 4.4-mile stretch of four-lane highway would lengthen State Route 162, known as Pellissippi Parkway, from where it ends at Old Knoxville Highway (State Route 33) to East Lamar Alexander Highway (State Route 73/U.S. 321) in Maryville.

The project, which would impact 56 properties and cost at least $60 million, is not without controversy. Citizens Against the Pellissippi Parkway Extension, “believe(s) this interstate highway is not needed, wastes state resources and will have negative impacts on the area along the route and on the quality of life in Blount County as a whole,” according to the group’s website, saveitdontpaveit.org. Besides loss of farmland, residences and businesses, CAPPE’s concerns include sprawl, traffic, water and air quality, noise, economic impact and the destruction of wildlife habitat and increased rates of roadkill.

State and local government officials, however, maintain the Pellissippi Parkway Extension will address needs such as “limited mobility options in Blount County and Maryville, poor local road network with substandard cross sections (with narrow lanes, sharp curves, and insufficient shoulders), lack of a northwest/east connection east of Alcoa and Maryville, safety issues on roadways in the area, and traffic congestion and poor levels of traffic operation on major arterial roads and intersections,” according to the Record of Decision signed by the Federal Highway Administration on Aug. 31, 2017.

The Pellissippi Parkway Extension has been part of the Knoxville regional transportation planning vision since 1977, according to a 2010 Draft Environmental Impact Statement, and has a long, storied history -- complete with a 2002 lawsuit from CAPPE, seeking to stop it. Nothing has happened publicly, however, since the Record of Decision selected a preferred route for the new stretch of road, which would cross Old Knoxville Highway, Wildwood Road, Brown School Road, Sevierville Road and Davis Ford Road before terminating near Morning Star Baptist Church in Maryville.
