Xeriscape or New Sod for a Sun City Georgetown Yard
Xeriscape or new sod in Sun City Georgetown: the three grasses Sun City allows, why new sod clashes with the two-day watering rule, and the rebates.
For most Sun City Georgetown yards, a xeriscape or a smaller lawn surrounded by planted beds is easier to get right than a full yard of new sod. Sun City allows only three lawn grasses, and new sod needs more water than Georgetown's two-day watering schedule allows unless the city grants a short variance.
The choice turns on three rule books before taste: the Sun City Texas Design Guidelines, Georgetown's watering rules, and Texas A&M AgriLife Extension's grass guidance.
What grass does Sun City allow in a lawn?
Sun City allows three lawn grasses. The Sun City Texas Community Association's design guidelines, approved May 21, 2026, state: "Permitted lawn grasses are hybrid Bermuda, hybrid Buffalo, and hybrid Zoysia."
The same section rules out the two grasses most Central Texas lawns are planted with: "Common Bermuda and St. Augustine grasses are prohibited because they are highly invasive." Artificial turf is not allowed in Sun City either, though the guidelines say the review committee, ModCom, will consider putting greens in rear yards.
What counts as a xeriscape in Sun City?
Sun City defines a xeriscape as a design that "will require 50% or less of the normal amount of irrigation as a turf-based design." A yard covered in gravel does not qualify. The guidelines require "differing color and texture for planted areas and inert areas" with "no extensive areas of a 'desert' or 'barren' appearance," and they let ModCom limit gravel, rock and cacti.
A xeriscaped Sun City yard is built from zones. Each zone is an inert or planted area of 100 to 500 square feet, a front or rear yard should have at least three of them, and at least one zone in each yard must be planted. Allowed bed materials include hardwood mulch, river rock, crushed stone, decomposed granite and granite pebbles. Our xeriscape design and installation work is laid out the same way, so the plan reads as a landscape rather than a gravel lot.
Can new sod take on Georgetown's watering schedule?
New sod is hard to establish on Georgetown's normal schedule. As of October 26, 2026, the City of Georgetown's water utility page says customers can follow "the two-day-per-week outdoor watering schedule and other Drought Stage 1 restrictions," with no irrigation on Mondays and none between 9 a.m. and 7 p.m. on any day.
Texas A&M AgriLife Extension's sod installation guide says, "In weather above 80 degrees F, new sod may need watering daily until it is well rooted," and recommends keeping the soil moist to a depth of 3 to 4 inches. Two days a week does not meet that.
Georgetown's answer is an irrigation variance. The city's askGTX article on irrigation variances says anyone "replacing existing sod" must apply, that a variance is "valid for 14 days from approval," that replacement projects "must cover at least 200 square feet," and that the city needs "three to five business days for processing." The same article warns: "Irrigation variances are not guaranteed during declared drought stages." Top dressing, seeding and aeration do not qualify.
Planting beds have an easier path. The city allows drip irrigation on your watering day within the 14-hour window, and hand watering with a hose or bucket is allowed any day, at any time.
If you keep a lawn, which grass suits Sun City?
All three allowed grasses handle Central Texas, with different tradeoffs. AgriLife's turfgrass selection guide says bermudagrass is "highly drought and traffic tolerant but requires full sunlight," and that buffalograss "does well as a low-maintenance lawn grass from Central to West Texas." Zoysiagrasses, the same guide says, "are drought-tolerant but tend to turn brown sooner than bermudagrass during an extended drought."
Zoysia also has newer research behind it. AgriLife's zoysiagrass management guide reports that a 2023 and 2024 study at the Dallas AgriLife Research and Education Center found Palisades zoysiagrass "can be maintained at acceptable levels at 48 percent ETo," a measure of water need. The same guide says warm-season grasses should be planted in late spring or early summer and that "late fall sodding or seeding can reduce the establishment success rate," which is a reason to plan a fall project around beds and leave the sod for spring. Our lawn replacement page covers how we match the grass to sun and shade.
How does Sun City approval work for a yard change?
Most landscape changes in Sun City need an application to ModCom before work starts. The guidelines tell homeowners to check the No-Paperwork List first, then submit an application for anything not on it.
| Step | What the guidelines say |
|---|---|
| Review | ModCom "aims to respond to the homeowner within 30 days, and will respond within 60 days of the submission." |
| Scope | "No more than three projects may be addressed in an application." |
| Start | Work must start within 120 days of approval. |
| Finish | Work must be completed within 60 days after it begins. |
Approval from ModCom does not replace the city's rules. The guidelines say Sun City homeowners "must adhere to all current City of Georgetown residential watering rules for irrigation of their landscapes."
Are there rebates for converting a lawn in Georgetown?
Yes, for Georgetown water customers. The city's Texas Grown Native Landscaping rebate covers converting irrigated turf to Texas native plants, up to $3,000 a year, and it requires the city's pre-approval before work begins. For fiscal year 2027, the city says residential customers can qualify for a combined total of $5,000 in rebates.
Smaller rebates apply to the irrigation itself: up to $150 for a smart controller and up to $75 for an irrigation check-up by a licensed irrigator. A city rebate and a ModCom approval are separate applications, so plan for both. When a conversion means moving spray zones to drip, our irrigation repair crew handles the valve and zone work the guidelines call for, including keeping lawn and drip on separate valves.
What we recommend for most Sun City yards
A hybrid plan usually fits best: a modest lawn of one of the three allowed grasses where you actually use it, and the rest in planted and inert zones on drip. That plan meets the guidelines, stays inside the two-day schedule once established, and avoids betting a whole yard of sod on a variance during a drought stage. B&B Landscaping & Masonry designs and builds these yards across Georgetown and Sun City, and we will walk the property with you, sketch the zones and help you assemble the ModCom application.
