Call 811!

Building a deck? Planting a tree? Installing a mailbox? Please call 811 before you begin any digging project. Every digging job requires a call – even small projects like planting trees or shrubs. If you hit an underground utility line while digging, you can harm yourself or those around you, disrupt service to an entire neighborhood and potentially be responsible for fines and repair costs. Whether you are a homeowner or a professional excavator, one call to 811 gets your underground utility lines marked for free. Protect yourself and those around you – call 811 every time.
