Artificial turf in Columbine, CO, for established back yards on flat clay lots.

Work between the patio, trees and fence.

A putting green does not need to take over a suburban back yard. Choose the putting line that matters, then leave room for walking and other uses. A pet area can be separate, particularly when its cleanup routine differs from how you want to use the lawn.

Show us existing patio edges and low spots. A turf installation should account for those conditions; it does not fix moving paving or structural ground problems.

Columbine crosses a county line.

Confirm the parcel’s county before checking land-use, grading or drainage requirements. Use the current documents for your own neighborhood association rather than a nearby Columbine community with a similar name.

Bring any written conditions to the visit and ask for the turf area, preparation, edging and disposal to be clear in the price. That makes different layouts easier to compare.

Clay over fill, graded flat half a century ago.

The USDA maps the Columbine area as Denver-Urban land complex on 0 to 2 percent slopes (USDA). The Denver soil, about 65% of the unit, is 33.5% clay at the surface over subsoil of about 50% clay, with slow drainage and high shrink-swell. Another 20% of the unit is mapped simply as urban land: the cut, fill and disturbed ground left when these subdivisions were mass-graded in the 1960s and '70s.

That is why patios heave, flatwork cracks and low spots pond. It also means nobody can say what's under a given yard without looking, because fill of unknown compaction can sit anywhere. So the free visit includes a look at the ground itself, and the base is designed around what turns up.

The lots are flat, with almost no natural fall, and decades of sprinkler water have been soaking into that clay. Turf needs no sprinklers at all, so that water stops.

Many Columbine water bills come straight from Denver Water.

Columbine is split among several Denver Water distributors. Columbine Water and Sanitation District is a Total Service distributor: Denver Water owns the system, reads each meter and bills each customer directly. Southwest Plaza Metropolitan District is Total Service too (Denver Water), and Southwest Metropolitan Water and Sanitation District, another distributor, serves homes across western Arapahoe, eastern Jefferson and northern Douglas counties (Southwest Metro Water).

Stage 1 allows two assigned days a week, outside the 10 a.m. to 6 p.m. window, with no watering in rain or high wind and none running onto pavement. Single-family violations go from a warning to $250, then $500, then $1,000, and on 26 August 2026 the board called an end to the lawn season: from 1 October, sprinklers and lawn watering stop entirely (Denver Water).

Don't wait on a rebate. The $750 turfgrass-removal discount run through Resource Central closed to new applications in March 2026, and it funds a living ColoradoScape rather than turf (Denver Water). The state's Turf Replacement Program stopped taking applications in March 2025, and homeowners couldn't apply to it directly anyway (Colorado Water Conservation Board).

No town hall. The county line first, then your HOA.

Columbine is unincorporated and the county line runs through it: Jefferson County governs most of it and Arapahoe County the eastern part (Wikipedia). Settle which side your parcel is on before you ask anyone about grading. The two counties have written the question differently, and the same back yard gets a different answer.

On the Jefferson side the office is Planning & Zoning and the threshold is published: land disturbance under half an acre, 21,780 square feet, is permissible without a grading permit, and a backyard pad is nowhere near that (Jefferson County). The performance standards apply whether or not a permit is required, so they shape the job anyway. Section 16 holds grading and erosion control at least 7 feet from your property boundaries and at least 25 feet from an occupied structure off your lot, wants flatwork or a foundation an excavation could affect underpinned or otherwise protected against settlement, and takes a letter from a Colorado registered professional engineer before a setback is waived (Jefferson County). So we plan the pad, the fall and the edges to sit inside them.

On the Arapahoe side there is no number to look up. Its Land Development Code, dated 12 May 2026, says no land disturbance shall occur on any property without first obtaining a GESC permit unless the GESC Manual exempts it, and leaves which projects need one to that separate manual (Arapahoe County). The code defines land disturbance as purposeful alteration of existing ground contour by excavation, grading, filling or removal of ground cover vegetation, which is what a turf base is. Ask Public Works and Development whether yours is exempt, and keep the answer.

A putting green is the open question on the Jefferson side. The county requires a Miscellaneous Permit for sport courts, and its list runs from basketball and pickleball courts through playground equipment and swimming pools to golf courses and other outdoor sports and recreation areas, with setbacks and height limits set by your zone district (Jefferson County). It never names putting greens. Put that question to Planning & Zoning in writing before you fix where a green goes.

For most homes the approval that matters comes from the neighborhood association. Columbine Knolls, Columbine West, Columbine Hills, Burning Tree, Leawood, Wynetka Ponds and the rest each run their own architectural committee, and Southwest Metro even keeps an HOA outreach page of newsletter copy for the associations it serves (Southwest Metro Water).

On a detached house, state law bars an association's design guidelines from ruling out nonvegetative turf in the back yard (SB23-178), so the committee's say is over the front yard and the details. Common ground is another matter; our guide to HOA turf rules explains where the line falls.
