Owings Mills-based Carroll Tree Service Inc., has been awarded a contract to prune and preserve Elm trees at the National Mall in Washington, the firm announced Monday.
The terms of the contract were not disclosed.
The Baltimore County commercial tree care company was tapped by Annapolis Junction-based Corman Construction, which was hired by the National Park Service to restore the reflecting pool.
Carroll will work to preserve the trees throughout the project, which is scheduled to be completed by spring 2012.
