A proposal for tree farm production in Southwest Philadelphia

Urban Arboriculture Philadelphia is a project by Dylan Salmons, a student in Pennsylvania State University’s undergraduate landscape architecture program.  Salmons participated in a studio entitled The Urban Arboretum: From Vacancy to Hybrid Landscape, a design course inspired by Matthew Langan’s eponymous proposal for the Urban Voids competition.  The Spring 2010 studio was taught by Tim Baird with assistance from Langan, a graduate of the program.

Urban Arboriculture Philadelphia is a park design whose visual, structural, and functional elements all descend from diagonal lines dramatically cutting through the site at odd angles with the surrounding street grid.  These lines evolve into a core of water management functions, including stormwater management, irrigation for tree and plant nurseries, and newly created riparian edge communities.  Arboriculture methods featured in this project include staggering planting cycles and a modular container system for tree production that stabilizes fragile ground, streamlines transplantation, and allows the containers to be reused.
