When archaeologists are planning a major project, there are several ways they can keep the public informed. Letters are sent to all involved landowners requesting permission to access the land and conduct investigations. These are usually followed up with visits to each household before any field work is undertaken. Press releases to local TV and newspapers keep people informed about what is going to happen in their community. Agencies such as the Department of Transportation hold public meetings where new construction plans are presented and the public has a chance to review the proposals. Often, the public are able to provide important information about unreported archaeological or historical resources that may be impacted by the project.
