Green Valley, Arizona

Green Valley is an unincorporated community and census-designated place (CDP) in Pima County, Arizona, United States.

[2] Green Valley is located along the western side of the Santa Cruz River at 31°51′N 111°0′W / 31.850°N 111.000°W / 31.850; -111.000 (31.8556, -111.0001).

Surrounded by copper mines, and near the cycling, hiking and birding areas of the Santa Rita Mountains, Green Valley is an unincorporated retirement community composed of 59 Homeowner Associations.

Green Valley has a borderline hot semi-arid/hot desert climate (Köppen BSh/BWh) with three seasons: a warm to mild winter with chilly nights from October through March; a hot, extremely dry summer season from April to late June; and a hot, relatively humid monsoon season from July through September.

Outside monsoon season, rainfall is uniformly scarce, having exceeded 4.0 inches or 100 millimetres only in October 2000 amongst other months.

Frosts occur 37 nights per winter on average, and daytime highs fail to top 50 °F or 10 °C on nine days.

[10] Freeport McMoRan's Sierrita mine is located in Green Valley and is one of the town's largest employers and is involved in investing in the community.

Four out of five of the recommendations suggested taking advantage the "Central Arizona Project (CAP) renewable water supplies, as well as recharge of the same".

[13] The report states, "the size of a pipeline that would convey Central Arizona Project water for direct use or recharge for the entire Upper Basin would need to be at least 72 inches in diameter.

Since 2007 the Upper Santa Cruz Providers and Users Group (USCPUG) has been working to bring all local water entities, including the Town of Sahuarita, to the same table.

It has joined with the U S Bureau of Reclamation to lay the groundwork for transportation and use of Colorado River water from the Central Arizona Project canal to greatly reduce reliance on pumping groundwater.

If a system is successfully completed, the excess pumping will be largely or fully eliminated.

The process through design and construction is expected to take several years with funding being the major challenge.

ETS – École de technologie supérieure of the Université du Québec, from Montreal, Quebec, Canada, won the competition.
