Marana residents will see an extension of The Loop trail from the Canyon Del Oro Wash to the west side of Interstate 10, thanks to a routine bank protection project.

The Marana Town Council unanimously approved a development agreement last Wednesday between the Pima County Flood Control District and a private developer to build bank protection along the north side of the CDO Wash between Thornydale Road and I-10. This area cannot be developed without securing infrastructure that prevents flooding and erosion.

Because the CDO Wash is a regional water course, the county’s Flood Control District is involved in establishing bank protection. And because the land in question is privately owned by Alta Vista Communities, they are splitting the cost with the county.
