The interim director of Upper Cumberland Development District has resigned, but not before pointing the finger of guilt at board members. “It is clear this board does not have the best interest of the agency’s employees, or those who are served throughout the Upper Cumberland region, by decisions that continue to cripple the agency financially,” said interim director Earl Carwile in his resignation letter. Carwile, a longtime employee at UCDD, was appointed Feb. 24 as its interim director by UCDD board members.
