The Benjamin Franklin Parkway rehabilitation project focuses on the preservation treatment of the tree plantings on two central medians of a grand boulevard in the City of Philadelphia designed by French urban planner Jacques Gréber (1882-1962). The site is owned by the Fairmount Park Commission, City of Philadelphia and was listed on the National Register of Historic Places in 1985. The project area is located in the 2000 through 2200 blocks of the Benjamin Franklin Parkway.

The decline and loss of the original, formally-spaced allée of double red oak (Quercus rubra) tree plantings stimulated a planning and implementation project that replaced these character-defining features. In many landscape preservation projects where replacement is an issue, public resistance to the removal of mature canopy trees has been an obstacle to a preservation treatment plan. In this case, however, public education was an integral part of a plan in which diseased and dying trees were removed and new trees, of mixed species, were planted in a specially formulated soil that promoted health and vigor and increased longevity.
