Pavement Management Overview
The functions of the Pavement Management staff are to perform inventory and compile data of the Town's system of roadways and to formulate pavement surface treatment recommendations and schedules.  The Pavement Management staff also monitors the construction of surface treatment projects for the Town, and represents the Town on the regional (PAG) Pavement Management Team.

The 2010/2011 ARRA1 funding provided money for overlays on sections of Tangerine Road, Rancho Vistoso Boulevard, Naranja Drive and Lambert Lane thus improving the pavement condition on 16.5 lane miles of pavement.  Our routine surface treatment program helped preserve the Town's systems of roads using advanced techniques on roughly 36 lane miles of Oro Valley pavement.
