How I Built This Network
Ada County Highway Department
Ada County, Idaho began a proactive management plan of its rapidly growing network in 1996. Today, the County has seen the overall average network condition improve by 20 points.
How did Ada County manage its expanding network needs? We’ll learn about their innovative zone rotation approach, how they’ve expanded their treatment toolbox, and how they’ve taken a proactive look at taxpayer communication. They’ll give an insider’s look at their approach to specific preservation and recycling treatments and help agencies consider things they can do today to spread limited resources further.
Next in a growing series of “How I did it” webinars, we’ll interview Ada County Highway Department’s Scott Forrey (Pavement Management Engineer) and Lloyd Carnegie (Maintenance Manager).
