Mission

The Common Ground Alliance is dedicated to preventing damage to underground utility infrastructure and protecting those who live and work near these important assets through the shared responsibility of our stakeholders.

About Missouri 811

Missouri 811 was established as a means to protect underground facilities and assist excavators and utilities in complying with Missouri's statute and OSHA Rules 1926.651. By using the service that Missouri 811 provides, the general public's safety and the environment also are protected.

Annual DIRT Reports

CGA and its Data Reporting & Evaluation Committee uses the data submitted to DIRT to produce DIRT Annual Reports, on-line interactive dashboards, and supplemental reports and tools providing a comprehensive accounting and analysis of excavation-related damages (and near miss events) to buried infrastructure in the U.S. and Canada.
