For the past twenty years the Tejido Group along with the College of Architecture, Planning & Landscape Architecture at the University of Arizona has been fortunate enough to have had the opportunity to develop and implement interdisciplinary design and planning studios in an array of cultural and environmental contexts. This Spring semester, Pima County, AZ. gave us the opportunity to participate in a wonderful project in Tucson along the Santa Cruz river corridor. The five mile long site presented our design team an array of critical environmental and social issues with which to contend, i.e., uncontrolled growth, economic stagnation, transportation inefficiencies, a dearth of healthy natural habitat and recreational opportunities, environmental degradation, as well as diminishing sense of place. Consequently, the primary intent of this project focused on the development of a sustainable urban living prototype for Pima County. A prototype that approaches sustainability across an array of dimensions: economic, environmental, cultural, aesthetic, and functional. Our master plan strives to encourage intelligent nodal development along the Santa Cruz river corridor in which dense, walkable mixed-use urban nodes are combined with strategically placed conservation easements that preserve, revitalize and interconnect the many unrealized / underutilized natural, cultural and economic amenities existing throughout the area.
