The Task Forces work product, entitled the Common Ground Study, provided a guide to underground utility damage prevention best practices in use throughout

If we can improve upon what you see here in order to do so, your input in helping us do so would be most appreciated. Common Ground Alliance 4 Best Practices Version 1.0 April 2003 Homeland S
