The intent of this project is to rehabilitate a portion of the Santa Cruz River and adjacent areas by designing strategies that operate on a variety of levels. This approach works in a range of scales benefiting both the environment and the community by implementing eco-responsive design. Expansion of the Interstate 10 has divided Tucson, creating a barrier between the two sides of the highway and resulting in limited connectivity. The plan functions to reconnect the separated sides and enhance access through transportation hubs, greenways, and trails. The addition of mixed use development encourages people to inhabit the site, creating a cultural center for activities and festivals which in turn will stimulate local businesses. The plan integrates a nature and urban creating a symbiotic relationship between the two. Greenways serve as protected corridors for both human and wildlife circulation to and from both natural and developed areas. Ultimately the Santa Cruz Master Plan revitalizes a disturbed riparian corridor while also creating a sustainable urban prototype in the arid southwest.
