Mission:

To promote the use of the Common Ground Best Practices by encouraging stakeholders to accept and fulfill their shared responsibility in damage prevention; to welcome all stakeholders within our region and encourage their participation on this committee; to educate both committee members and non-members regarding Common Ground Best Practices; to identify issues concerning damage prevention within our region and attempt to construct practices to resolve them; to exchange ideas and information with other Regional CGA Committees. When a new damage prevention practice is created, the committee may forward the practice onto the appropriate CGA Committee for their consideration as a best practice. Our committee's efforts in damage prevention will help eliminate damages to underground facilities, interruption to vital services, safety risks, accidents and fatalities.
