The Papago Park/City Boundary project is a collaborative effort between the cities of Scottsdale and Phoenix to commission a work of art which serves both as a boundary marker for the two cities as well as an entrance into Papago Park, an 890 acre desert park in southeast Phoenix.
Pinto and Martino’s approach to the project centers around Papago Parks identity as a major historic and ecological boundary marker within the valley. The design consists of seven 16 foot high vertical markers sited around a 240 foot long wall with seven branches radiating from its center referencing a tree of life form. The piece is made from stacked and mortared field stone in a manner similar to the parks historical W.P.A. ramadas. The markers serve as axis for directing viewers to municipal, historical and natural sites in the valley -- they also align with the Summer Solstice, the longest farming day of the year. The wall structure, which forms the stem of the plant, functions as a water-harvesting devise and aqueduct. Run-off from summer storms is captured and diverted through a channel in the wall onto each of the seven farming terraces which are planted with native plants.
