Ask a newer Jarrell resident what there is to do in July and you tend to get a shrug and a drive to Georgetown. Ask someone who has been through a couple of Sonterra summers and you get a specific answer keyed to specific addresses. The town of 6,800-plus runs on a compact weekly rhythm anchored by the Sonterra Municipal Utility District calendar, a handful of park venues off Sonterra Boulevard and CR 313, and a slowly reshaping I-35 frontage that will look different by the time school starts. This is that rhythm, mapped by street address.
The July And August Week, By The Date
Sonterra MUD confirmed summer programs are open for registration, and the neighborhood venues at 401 Fighting Seabees Run and 510 Sonterra Boulevard are doing most of the heavy lifting on the community-event side. A few of the dated anchors residents can actually put on the fridge:
- Fri, Jul 24 — Movie Night 2, Cars, 8:00 PM at 510 Sonterra Blvd
- Sat, Jul 25 — Rising Country Stars of Texas Concert, 6:00 PM at 1600 CR 305
- Tue, Jul 28 — Happy Hour at The Lucky Penny, via the Jarrell Chamber
- Sat, Aug 1 — Movie Night 3, How to Train Your Dragon, 6:45 PM at Fighting Seabees Run
- Mon, Aug 3 — Bake Boss: Session 3, 9:00 AM at 510 Sonterra Blvd
- Tue, Aug 11 — Metro Area Job Fair through the Chamber
- Wed, Aug 19 — August Networking Luncheon through the Chamber
That's five nights and two daytime blocks in a rolling four-week window, most of them free or low-cost, all inside the 76537 ZIP. The Chamber's July calendar also lists a City Council meeting on Aug 4, which matters more to residents than it sounds — this is when the water and parks conversations happen out loud.
The Two Addresses Doing Most Of The Work
If you're new to Jarrell, two coordinates cover roughly 80% of what the community calendar points you toward.
510 Sonterra Blvd is the Sonterra Pool and Splashpad, the aquatic hub run by Sonterra MUD Parks and Recreation. It's the venue for Movie Night 2 and Bake Boss, and it opens for the season every Memorial Day weekend. The main amenity center around it stacks two pools, splash pads, a playscape, a kid's soccer field, skateboard pump tracks, a BMX course, and crushed granite trails inside the Sonterra master-planned community footprint.
401 Fighting Seabees Run is the second engine — the park hosting the How to Train Your Dragon movie night on Aug 1 and, earlier in July, the FIFA World Cup Semi-Finals watch party on the 15th. This is the address to know if your kids ask what's happening on a Saturday and you don't want to drive south.
Beyond those two, Sonterra MUD's facility list quietly includes seven more park and rec addresses — 200 Azurite Drive, 100 Bronze Cove, 1617 CR 313 (where the Triple Threat Basketball Camp Session 2 ran Jul 18), 601 Sonterra Blvd, 320 and 113 Limestone Terrace, plus the pool. Most residents only use two or three of them. The other five are the reason Sonterra MUD posted a Recreation Supervisor role earlier this spring — the district is staffing up to program space that's currently underused.
The Stage 2 Water Notice Changed The Backyard Calendar
One quiet piece of context every resident with a lawn should know: Stage 2 Voluntary Water Conservation has been in effect since Oct 2, 2025, per the City of Jarrell. Voluntary is doing a lot of work in that sentence. It is not an ordinance you can be fined under today, but it's the framework the city and Sonterra MUD are using to shape what "normal" summer irrigation looks like this year.
Practically, that changes two things about a July weekend. First, the community splash pad at 510 Sonterra Blvd carries more of the load for kid cooldown, because filling a home kiddie pool at 2:00 PM in triple digits is exactly the pattern Stage 2 asks residents to soften. Second, the weekend-morning routine tilts earlier — mow, water, done before 10:00 AM — which is why the 9:00 AM Bake Boss slot on Aug 3 and the 6:45 PM movie start on Aug 1 both make sense the way they're scheduled. Sonterra MUD's own advisories reinforce the same message.
If you moved here in the last 12 months, this is the piece that isn't obvious. Jarrell's summer schedule is bent around the water calendar, not the other way around.
What's Actually Opening At Exit 275
Two development anchors on the I-35 corridor are worth knowing about because they'll reshape the drive between now and next summer.
Walmart at 860 FB Schwertner Rd. According to a Texas Department of Licensing and Regulation filing reported in May, Walmart is building a new 174,579-square-foot store on FB Schwertner Rd with a construction timeline running September 2026 to August 2027 and a project cost estimated at $12.2 million. The nearest existing Walmarts today are in Georgetown and Belton. For residents who currently drive 17 miles south to Wolf Ranch or an even longer haul up to Belton for a grocery run, the August 2027 target is the timeline that matters. Between now and then, expect construction traffic on FB Schwertner and the frontage road at the exit.
Solana Ranch, north of town. The 9,000-acre planned community from DMB Development, first surfaced by the Austin Business Journal in early 2023 on the former Michaux family ranch, is still moving. DMB's Herrington told reporters late last year the company was working through engineering studies for wastewater, power, water, and internet, planned to begin outreach to homebuilders in early 2026, and was targeting the first pieces of the community to open in late 2026. At full buildout, the project could reach 40,000 to 50,000 residents — roughly the current population of Hutto for comparison. Split between Williamson and Bell counties, it sits between Georgetown and Temple, which puts most of its early impact on the same I-35 corridor Jarrell commuters already use.
Neither project changes what to do this weekend. Both change the answer to "what will Exit 275 look like when my kid starts kindergarten," and that's a question a lot of Sonterra residents are quietly asking.
A Working Weekend Template
Put together, the calendar and the venues suggest a template that keeps a Jarrell weekend inside the ZIP code without the drive to Round Rock:
- Saturday morning before 10:00 AM — yard work and any home watering, per Stage 2 guidance.
- Saturday late morning — splash pad at 510 Sonterra Blvd, or the trails and pump track around the main Sonterra amenity center.
- Saturday early evening — concert night if the date lines up (Rising Country Stars on Jul 25 at 1600 CR 305), or movie night at Fighting Seabees Run when scheduled.
- Sunday — one of the quieter park addresses on the Sonterra MUD list (100 Bronze Cove and 200 Azurite Drive are the least crowded), plus grocery pickup planned around the current Georgetown or Belton run until the FB Schwertner store opens.
The pattern is more useful than any single event. Once you know that Sonterra MUD is the operator behind most of what shows up on the community calendar, that Fighting Seabees Run is where the family-programmed nights land, and that Stage 2 is shaping the daytime routine, the summer stops feeling scattered. It starts feeling like a schedule you can actually plan around.
That's the Jarrell most listings pages don't show you.
