Excavating questions, answered by experts

Yes, most services include site leveling and foundation work. Confirm with your contractor for specifics.

Most municipalities require excavation permits for any significant digging, especially if the excavation affects utilities or public property. However, permits for excavation depend on your local government and the scope of the project. Hire an experienced contractor for your excavation job so that they can be the ones to deal with permitting, not you. 

The easier way to find buried sprinkler lines is to use the plan from the professionals who installed the system. If you don’t have professional plans, listen for running water on your lawn when you turn on the system. You may also spot wet areas, giving you an idea of where the heads are. Once you find the sprinkler heads, you’ll likely be able to connect the dots between them, revealing the system below.

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.

You can bury underground electrical wire six inches deep—but only if you use a rigid metal electrical conduit. For rigid, non-metallic conduits, bury the wire at least 12 inches deep. If using an underground feeder cable rated for direct burial, you'll need to place it at least 18 inches deep, as it has no conduit for extra protection.
