The Olmsted Linear Park Alliance (OLPA) is a public-private partnership founded in 1997. Its mission is to implement a master plan adopted by the city of Atlanta, DeKalb County and Fernbank, Inc. Work on five segments—Oak Grove, Shadyside, Virgilee, Dellwood and Springdale —has given the parks back to the public for the enjoyment of all. The last segment, Deepdene, is almost complete. Already, neighbors and visitors are walking the paths along the restored creek bed and appreciating the native plants returning to life with the removal of the non-native invasive species.
