In 1997 the idea of restoring the banks of the Santa Cruz river was born.
Now, 16 years later, work has begun.
Voters passed a $14 million bond issue for the project but the recession and federal dollars set it back a few years.
But ground has been broken, the plans on the table, the money approved and the need to restore he ecosystem agreed on.
"Things will look a lot different with an additional 10,000 new trees and shrubs," Deirdre Brosnihan, the Project Manager.
The project is called Paseo de las Iglesias and it will change a lot of things around the river.
It will gather and protect the wildlife, lizards and native vegetation.
There will parking, restrooms and several additional miles of The Loop, a bike and pedestrian path encircling Tucson.
The first phase is a mile and a half from Silverlake to Ajo. But future projects will extend the bank restoration and preservation from Ajo to Camino del Cerro.
