Real ground. Real work.

All services

STA 4+00Know your ground

The plains, plainly explained.

Flat ground and big sky hide a lot. Here’s what shapes every dig east of Denver.

A typical plains profile, simplified. Every lot is different.

Clay that moves

Much of the Front Range plains has clay that swells when wet and shrinks when dry. Grading water away from foundations is the best defense.

About 36 inches of frost

The Denver–Aurora area commonly designs for about 36 inches of frost. Water lines go deeper; your building department sets the footing depth.

A county line through town

Strasburg and Bennett sit in both Adams and Arapahoe counties, so your parcel decides who permits your septic system.

811 before every dig

Colorado 811 asks for at least three business days’ notice. Lines you own, like power to a barn, usually aren’t marked.

STA 7+00Straight answers

Septic & sitework questions.

What is Colorado Regulation 43?

Regulation 43 (5 CCR 1002-43) is Colorado’s statewide rule for on-site wastewater treatment systems (OWTS), the legal name for septic systems. It sets the minimum standards for siting, soil evaluation, design, installation, repair and maintenance of systems up to 2,000 gallons per day.

The state sets the floor; county and district public health agencies adopt their own septic regulations on top of it and issue the actual permits. So your permit, inspections and any local extras come from your county’s health department, not from the state.

What is a soil profile test pit?

A soil profile test pit is an excavated hole where a trained technician looks at and feels the soil layers to decide what kind of septic system the ground can handle. Regulation 43 requires at least two of them for a new system.

The pits go down to any limiting layer or 4 feet below where the system’s infiltrative surface will be, whichever comes first, and at least one goes where conditions are expected to be the most limiting. The technician reads soil texture, structure and any signs of seasonal water to set the soil type and the long-term acceptance rate the design is sized on.

What are expansive clay soils, and do we have them here?

Expansive clay soils swell when they get wet and shrink when they dry out. They are common along Colorado’s Front Range, including the plains east of Denver and Aurora, though soils change from lot to lot.

The swelling can push up slabs, sidewalks and driveways and crack foundations over time. Water is what sets it off, which is why drainage and grading matter so much here.

What makes a gravel driveway last on the plains?

Shape and drainage. A gravel driveway lasts when it has a solid base, a crown so water runs off to the sides, ditches or swales to carry that water away, and culverts where it crosses a drainage.

Surface gravel only works on top of that. Without the shape, new gravel gets pushed aside, rutted and washed out.

Do I have to call 811 before digging in Colorado?

Yes. Colorado law requires anyone digging, homeowners included, to contact Colorado 811 before excavating. Colorado 811’s current guidance is to call or submit a request online at least three business days before you dig.

The service is free. Utilities mark their lines with paint or flags, and the marks are generally good for about 30 days. When we dig, we call in the locate.

What affects the cost of excavation and grading?

The main factors are access to the site, how much material is moved, the soil (clay, rock or groundwater), trench length and depth, material brought in or hauled off, utilities in the way, permit requirements and how much restoration the site needs afterward.

That’s why we look at the site before quoting. Two jobs that sound the same on the phone can be very different on the ground.
