JKDA created three graphs for the William Penn Foundation's open space preservation and water purity initiatives in 22 counties in Pennsylvania and New Jersey. The graphs deal with the amount of change in preserved open space by county, referendums on open space preservation by local governments (far right), and comparisons in water quality in the grantmaking area and statewide (near right). JKDA also evaluated maps made by the Delaware Valley Regional Planning Commission and offered constructive suggestions for their improvement, which were successfully implemented.
