Public Meetings and Listening Posts (a type of traveling open house) provided opportunities for the general public to hear about recent findings, ongoing technical studies, and the decision-making process. These meetings also provided the public with opportunities to comment on the project.  See the Public Meeting Materials tabs below and click on the heading to learn more.

As an additional forum for public input,  DOT&PF created an open advisory committee of interested/affected community members and local/regional interest group representatives. This group, the Stakeholder Sounding Board (SSB), met to discuss project issues and share concerns directly with DOT&PF.

The SSB was an advisory committee of community members and local/regional interest group representatives. The purpose of the group was to provide a regular forum to discuss the Sterling Highway Supplemental Environmental Impact Statement preliminary alternatives with the community and other interested stakeholders. Meetings were facilitated and conducted in a workshop format.

To encourage participation of all interested parties in the SSB, notices of meetings were sent to all (350+) property owners and residents of Cooper Landing, Cooper Landing business owners, and the more than 2,000 people on our project mailing list. While participation on the SSB was open to anyone, DOT&PF identified the following list of organizations, agencies, interest groups, and others who may be impacted by the project to ensure that they are receiving information and encourage them to participate in the process.
