About the Missouri Common Ground Alliance
We promote communication among responsible parties to identify and encourage the use of Best Practices for underground facility damage prevention for public safety and welfare.
We accomplish this through promoting effective communication of Best Practices for the prevention of underground facility damage and heightened safety initiatives to all responsible parties and stakeholders.


About the Missouri Common Ground Alliance
We work cooperatively with excavators, utilities, insurance companies, One Call, government agencies, engineering, agriculture, and many other groups. We seek to inform and educate through dynamic and practical training. By promoting the use of best practices, we serve as a catalyst for change through innovative and impactful education and advocacy.
As a recognized leader in damage prevention nationwide, our group works tirelessly to save lives in Missouri and beyond through outside-the-box solutions and answers to problems facing excavators and utility companies. In addition to training and education, the Missouri Common Ground Alliance participates in outreach initiatives and supports members in local efforts to improve public safety regarding underground utilities and facilities.
