1994-2003

Water and housing, and their accompanying conflicts, dominated the decade. The 1990 census showed a 3-fold increase in residents, to 6,670, gained through annexation and development of land.

In 1996, the Oro Valley Water Utility was created through the purchase of private water companies. More water company purchases would follow, allowing the town to better control its water resource while accumulating rights to Central Arizona Project water.

In 1997, to halt a battle over development, the Pima County Supervisors spent $1 million to buy 300 acres of Honeybee Canyon. At the same time, the Town of Tortolita was incorporated in September 1997. Oro Valley officials fought against this new town on its western edge, and eventually Tortolita was dissolved.

In 1998, Pima County and Oro Valley entered an agreement to generate money for the creation of Riverfront Park. It opened in 2000, the same year Oro Valley purchased the Naranja Townsite that today is the site of major recreational investment and activity.

Institutions opened, to include the U.S. Post Office on La Canada in 1998, the Oro Valley Branch of the Pima County Library in 2002, and the Coyote Run transit service – now Sun Shuttle – in 1996. Wilson K-8 School, Ironwood Ridge High School and Painted Sky Elementary School all opened during the 10-year span.

Ventana Medical Systems, now Roche Tissue Diagnostics, opened its doors in Oro Valley’s Innovation Park in 2001. Today, Roche is the community’s largest private employer.
