Artificial turf cost in Northern Colorado: two yards the same size can need different work

01Why does the ground under the lawn matter so much?

Because much of Northern Colorado sits on clay, and turf is only as flat and dry as the base under it.

• The Colorado Geological Survey calls expansive soil “Colorado’s most significant geologic hazard” (CGS).
• Federal soil surveys rate the Nunn and Weld soils, common around the Larimer foothill towns, Longmont and Frederick–Dacono, as limited by shrink-swell, while the sandier Olney, Otero, Vona and Kim soils are not flagged for it (USDA-NRCS soil survey data).
• Greeley’s water department says local soils “tend to be shallow with a layer of hard clay, sometimes just inches below the surface” (City of Greeley).
• Longmont tells residents that its “clay soils absorb water slowly” (City of Longmont).

On a quote, that shows up as how deep the digging goes, what base material goes in and how it is compacted, and how water leaves the turf area. The Colorado Geological Survey lists poor surface drainage near foundations among the landscaping problems on expansive soils, so the slope away from the house matters too.

02What does taking out the lawn involve?

Cutting out the sod and roots, hauling it away, and capping or rerouting the sprinkler zones that watered it. A thick old lawn, or a yard full of rock and roots, takes longer to clear.

03How does access change the job?

Whether a machine can reach the backyard or everything moves by wheelbarrow through a side gate; steps and slopes along the way; and how far the base material comes in and the old lawn goes out.

04What about edges and borders?

Every place turf meets a bed, concrete, a fence or a tree needs an edge that holds. Long, curving borders and many small beds add work; one open rectangle adds little.

05Do dogs, putting greens or play areas change the price?

Yes, because each asks something different of the turf and the base:

• Dog areas: the infill, the drainage under the turf, and somewhere to rinse.
• Putting greens: a shorter, denser surface, cups and fringe, and shaping the contours.
• Play areas: padding under the turf where children climb and fall.

06Does the turf product itself matter?

Pile height, face weight, backing and infill all vary, and so does the price. Some towns set minimums: Firestone’s code sets a minimum pile height, face weight and base depth, and bans crumb rubber infill (Firestone Development Code 16.6.4). Colorado has also barred installing artificial turf with intentionally added PFAS since the start of 2026 (SB24-081), so ask for each product’s PFAS documentation.

07Do HOA approval and town permits add cost?

They add steps and time more than money:

• An HOA’s architectural review needs a packet: a layout, the product sheet and a base and drainage section. Our guide to HOA approval for artificial turf lists what goes in it.
• Firestone requires a town permit before installation, with no fee for single-family homes. Greeley is drafting a permit path for front-yard turf on houses (council status report). Other towns are in our guide to artificial turf rules in Northern Colorado.
• No Northern Colorado water-provider rebate we checked pays for artificial turf; see our guide to turf rebates.

08What should I compare between quotes?

• How deep the excavation goes, the base material, and how it is compacted.
• How water drains, especially on clay.
• The product: its specification sheet and PFAS documentation.
• The edging.
• The infill, especially for dogs.
• Whether lawn removal, haul-off and sprinkler capping are included.
• Who prepares the HOA packet and any town permit.
