For Immediate Release: March 9, 2023 

Edmond McDavis III Appointed Director of Tennessee Delta Alliance

MEMPHIS, TENN – (March 9, 2023) Edmond McDavis III was recently appointed Director of the Tennessee Delta Alliance, an organization which oversees environmental and beautification efforts for the Great River Road National Scenic Byway. The group is also working towards establishing a water-based regional affiliation for Keep America Beautiful, to service the counties of Dyer, Lake, Lauderdale, Shelby and Tipton. For 16 years, McDavis has served in various roles supporting local affiliates for Keep Tennessee Beautiful. 

TDA is funded through a grant with the Tennessee Department of Transportation. The grant supports Governor Clement’s Executive Order #23 (1965), establishing a Mississippi River Parkway Commission for Tennessee. The Alliance is part of the University of Memphis’ Center for Regional Economic Enrichment.

“I am excited to work for the Alliance in this important role, to benefit the communities of West Tennessee.,” McDavis said. “Caring for the region in and around the Mississippi River, one of the world’s major river systems, protects water quality and the environment, and improves the experience of those visiting West Tennessee.”

The Alliance has recently been building partnerships with local officials to deliver on the group’s goals of enriching communities. Communities in the Alliance’s five county service area will receive additional grant support, volunteer engagement, fundraising, and education.

The Alliance was recently awarded a $20,000 Cigarette Litter Prevention Program Grant from Keep America Beautiful. Grant funds will be used to install cigarette receptacles in public areas within the Alliance’s five counties service area. This spring, the Alliance will host a series of cleanups at boat ramps and parks in Dyer, Tipton, Lake, and Shelby counties. Fall cleanups are additionally being planned and event details will be announced as available.
