Thinking about replacing your lawn with a xeriscape, but not sure what it’s going to cost? You’re not alone — it’s the first question almost every Denver homeowner asks. After building xeriscapes across the Denver metro, here’s what projects actually run and what drives the price up or down.
Average Costs: 💰 Average Xeriscape Costs in Denver
Most full professional installs in Denver run between $8 and $20 per square foot. That covers design, materials, labor, and drip irrigation setup. If you’re new to xeriscaping, start with our guide to xeriscaping in Denver.
A small front yard around 500 sq ft typically costs between $4,000 and $8,000. A larger lot pushing 2,000 sq ft or more will usually run $15,000 to $30,000+, depending on how much hardscape is involved.
What Drives Cost: 🪨 What Drives the Price Up
The biggest cost factors are hardscape elements — flagstone patios, concrete pavers, boulders, and custom fencing. Plants are actually one of the cheaper parts of a xeriscape build — especially if you’re using native or native-friendly plants, which can help save money by requiring less water. It’s the labor and materials around them that add up.
Water can be the most expensive ongoing cost as it relates to your landscaping, and switching to a xeriscaping landscape can help save you both time, as it requires less maintenance, and utility costs, as drought-tolerant plants require less water.
Soil prep is another thing people overlook. Denver’s clay soil needs serious amendment before anything goes in. Skipping it is the number-one reason xeriscape projects struggle in year one, so it’s worth getting right from the start.
💧 Xeriscaping Water Costs
Beyond the cost of completing your xeriscape project are the ongoing costs of maintaining your landscape. That’s where xeriscaping shines. While some projects may be deployed without additional water augmentation (i.e., just what Mother Nature gives us), many Denver xeriscapes rely on drip irrigation systems to provide a little additional support while still dramatically reducing water waste compared to sprinkler systems and grass.
Recent updates in 2026 from the Denver Post highlight that several metro area cities, including Denver, Thornton, and Aurora, are implementing stricter watering restrictions this season due to persistent drought conditions. These new regulations underscore the growing importance of shifting toward water-wise landscaping to ensure long-term resilience and compliance with local conservation mandates.
In Denver, xeriscaping typically saves homeowners between 50% and 75% on their outdoor water use. Since outdoor irrigation can account for half of a Denver household’s annual water consumption, this translates to a massive reduction in both environmental impact and monthly utility costs.
Key Savings Statistics for Denver
Data from local studies and Denver Water highlights the following average savings:
-
Gallons Saved: You can save roughly 19 to 33 gallons of water per year for every square foot of Kentucky bluegrass turf you replace with xeriscape.
-
Annual Volume: One Denver-area case study showed a homeowner saving approximately 133,000 gallons per year by fully converting a traditional turf lawn.
-
Cost Efficiency: While xeriscaping has an upfront cost, the estimated savings on water bills are roughly $0.36 per square foot annually.
Financial Incentives and Rebates
Denver Water and local organizations provide several programs to offset the initial investment:
| Program | Benefit | Details |
| Xeriscape Incentive | Up to $2,000 | For qualifying projects that replace water-intensive turf. |
| Turf Replacement | Up to $750 | Discounts for removing at least 200 sq. ft. of Kentucky bluegrass. |
| Garden In A Box | Discounted Kits | Professionally designed, low-water plant kits that are “plant-by-number.” |
Why the Savings Are So High in Colorado
Traditional Kentucky bluegrass requires about 18,500 gallons of water per month for a 5,000 sq. ft. lawn during a typical Colorado summer. In contrast, a well-designed xeriscape uses native plants adapted to Denver’s semi-arid climate (averaging only 15–17 inches of precipitation per year) and requires little to no supplemental water once established.
Note: Much of the savings (up to two-thirds) actually comes from upgrading to drip irrigation, which is roughly 90% efficient compared to the 50–70% efficiency of traditional spray heads.
Most homeowners don’t realize money is available to help cover the cost. Denver Water and several surrounding municipalities offer lawn-replacement rebates ranging from $1 to $3 per square foot for qualifying xeriscaping projects. On a 1,000 sq ft yard, that’s potentially $1,000 to $3,000 back. You have to apply before the project starts — so look into this early.
In Denver, the $2,000 xeriscape incentive is primarily managed through two channels: direct turf-removal programs for residential homeowners and the Landscape Transformation Assistance Program (LTAP) for larger properties or HOAs.
Since you are managing a landscaping LLC, these requirements are particularly relevant for both your own projects and the guidance you provide to clients.
1. Residential Turf Removal (Resource Central Partnership)
Denver Water partners with the nonprofit Resource Central to offer a “Lawn Replacement Program.”
-
Rebate Amount: Generally $500 to $750 in discounts for turf removal or “Garden In A Box” kits. (Some surrounding municipalities offer the full $2,000, so it is worth checking the specific water provider for each job site).
-
Minimum Area: You must remove at least 200 square feet of living, water-intensive turfgrass (Kentucky bluegrass).
-
Plant Coverage: The new design must include at least 50% plant coverage at maturity.
-
Prohibited Materials: Artificial turf, water features, and strictly hardscaped areas (rock-only) do not qualify.
-
Timing: Applications typically open in early March (now) and are awarded on a first-come, first-served basis.
2. Landscape Transformation Assistance Program (LTAP)
For commercial properties, public spaces, or “Small Landscapes” (under 7,000 sq. ft.), Denver Water offers a more robust incentive.
-
Incentive Amount: Up to $2,000 for residential projects or $10,000 for small landscapes, covering up to 50% of project costs (design, materials, and labor).
-
Pre-Approval is Mandatory: You must submit an Initial Intake Form and receive approval before breaking ground.
-
Irrigation Requirements: You must provide a plan showing how the irrigation will be modified (typically switching to high-efficiency drip systems).
-
Approved Plants: Plants must be selected from an approved “water-wise” list suitable for the Denver-metro climate.
| Feature | Resource Central (Residential) | LTAP (Small Landscape/HOA) |
| Max Incentive | ~$750 | Up to $10,000 |
| Min Square Footage | 200 sq. ft. | Up to 7,000 sq. ft. |
| Typical Pay-out | Discount/Service Credit | Reimbursement Check/Credit |
| Planting Rule | 50% coverage at maturity | 50% coverage at maturity |
| Pre-Inspection | Required (Photos) | Required (Site Consultation) |
Important for 2026 Projects
-
The “First-Come” Rule: Funding for these programs is strictly limited. Denver Water usually exhausts its budget by late spring/early summer.
-
Documentation: Ensure you have “before” photos of a green, maintained lawn. Most programs will deny a rebate if the grass is already dead or replaced by dirt/weeds before the application is reviewed.
Is It Worth It: ✅ Is It Worth It
Most Denver homeowners who make the switch see water bills drop 40 to 60 percent during summer months. Add in zero mowing, no fertilizing, and minimal seasonal upkeep — most projects pay for themselves within a few years.
Denver’s semi-arid climate makes maintaining a traditional lawn an uphill battle every summer. A well-built xeriscape just works with the environment instead of fighting it.
