This plan of Fairmount and vicinity, drawn in 1839 by Frederick Graff, Sr., shows a birds-eye view of the same details as the isometric view created by his son four years later. The largest, eastern basin of the reservoir had not yet been divided into two. The South Garden was just one year from completion; because of the lack of detail, the plan for the North Garden appears to have been little more than a proposal. The bed of the Philadelphia and Columbia Railroad is shown bracketed by Pennsylvania Avenue.
