Community Construction Management Plans

Our Community Construction Management Plans (CCMP) outline how the public can provide ongoing input into construction decisions that help to avoid, minimize, and/or mitigate the effects of construction activities on historic and other properties. The plans also guide the actions of our hired construction contractors, describe best management practices they are to follow, and provide opportunities for WSDOT to keep the public informed and gather input that improves our construction practices.
