What’s Next? • Continue responding to service requests with isolated spot repairs (i.e. pothole patching) • Consider machine patching, dig outs, or other surface treatments • Review the “Preservation” routes • Re-Evaluate the common road segments between 2015 and 2017 • Committee’s thoughts and recommendations?
