Excavating questions, answered by experts

In most areas, you will need a permit for excavation work, even if the project only involves grading or yard leveling. Excavation permits help protect the topography in your area and can avoid issues with poor drainage. In most cases, your excavation company will know whether or not permits are required and will even pull them and close them out for you before and after the job. You can also verify whether permits are necessary by calling your local building department and explaining the proposed project.

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.

Drilled wells have a pipe sticking up that’s covered in a plastic or metal casing. On the other hand, a dug well will look like a big hole in the ground and is more similar to what you’d see in a fantasy or Western movie. If you want to be sure, contact the city for documentation on your property’s construction and excavation history. 

The cost to dig a trench ranges from $400 to $1,200 per 100 linear feet, depending on the soil, depth, and width. Plan to spend $5 to $12 per linear foot for trenching (it’ll be on the higher end if you have rocky soil). Renting a trencher costs $100 to $250 per hour, depending on the type of trencher. 

Yes, an excavation company is the best option for land grading and yard leveling. General landscapers might be able to tackle these projects, but an excavation company will do a better job because they’re used to operating the necessary heavy machinery. Landscapers might opt to do the work manually, which takes much longer and could cost you more in labor fees. Finally, excavation companies will understand local regulations and know when you need permits to legalize the work, while a landscaper might not.
