For two summers now, the drive along Mountain View Corridor past 13400 South has looked the same: graded dirt, a chain-link perimeter, and a rendering on a construction sign that residents have learned not to trust too much. This month, that changes. Steel frames have gone up on the shell buildings, and for the first time the site reads as something more than a promise. At the same time, the free outdoor calendar that's carried Herriman through the warm months is down to its last two dates of the season.
Those two facts are connected in a way that's easy to miss if you only skim the city's event page or the retail announcements separately. Herriman has spent years building outdoor life faster than it built the errand-running infrastructure to support it, which is why a Target run has meant leaving the city for most residents who moved here in the last decade. This August is the first month where both timelines are visible at once: the community calendar winding down, and the retail promise finally looking like something under a roof.
Tonight Closes a Loop That's Been Open Since June
The Summer Sunset Series at J. Lynn Crane Park has run monthly since early summer, and tonight, August 10, is the safety and back-to-school readiness event, the second-to-last date on the 2026 calendar. It runs 5 to 8 p.m. at the plaza behind Herriman City Hall, the same footprint that hosted July's foam party.
The bigger date to know about is a week and a half out. On August 18, Krank-It-Up Productions and Herriman City are staging a car show at Crane Park, with load-in from 3 to 5 p.m., display running until 8:30, and awards at 7:45. It runs alongside the regular vendor market and food truck lineup that's part of the Sunset Series setup, so the plaza gets a full row of classic and modern cars on top of the usual food and shopping draws. After that, the series closes on September 14 with an inflatable fun run, and Crane Park settles into its fall rhythm.
If there's one night this month worth building an evening around, it's the 18th, not because it's flashy, but because it's the last time this summer that a car show, a vendor market, and food trucks all stack on the same block at the same hour.
What's Actually Rising at 13400 South
The Commons at Herriman Towne Center broke ground on June 27, 2025, when city officials and representatives from Elevated Property Company marked the start of construction on the 13400 South site, just west of Mountain View Corridor. The city's own account of that day describes plans for more than 200,000 square feet of retail and restaurant space anchored by a large-format store, on a site that's been zoned for commercial use for more than a decade without anything breaking ground.
The construction numbers give a clearer sense of scale than the renderings did. According to Robinson Construction's project page, the three retail shell buildings on site span roughly 215,837 square feet combined, with construction starting August 28, 2025, and substantial completion for those shells targeted for March 2, 2026. That completion date matters for reading the site today: the shells have had roughly five months to move through tenant buildout by the time this post goes up, which lines up with steel and framing finally being visible from the road this summer instead of just graded lots.
The tenants residents have been asking about longest are both confirmed. Target is the anchor. Trader Joe's announced in October 2025 that it would open its seventh Utah location here, directly adjacent to the CVS Pharmacy on site, with construction already underway at the time of the announcement and doors expected to open sometime in 2026. City communications manager Jonathan LaFollette told KSL that after eight years with the city, Target and Trader Joe's were "the most frequently wished for among residents." No exact opening date has been published for either store as of this writing, but the shells are done, the anchors are locked in, and the wait has an end point now instead of just a rendering.
The Park That Finally Grew Grass
A few blocks southeast, Mountain Ridge Park has been going through its own version of the same delay-then-arrival pattern. The city opened the 9.6-acre park along 13800 South last September with a playground, pavilion, restrooms, parking, and a walking trail, but held the grass playing fields back for a later phase. That phase is this year. The fields are now available for use, which changes what the park is actually good for: it went from a playground-with-a-view to a place you can bring a soccer ball or a picnic blanket and use the open ground.
What hasn't arrived yet is worth noting too. The city's own amenity listing for the park still shows only the grass play area, playground, restroom, pavilion, walking trail, and parking lot. No splash pad, no pickleball courts. Those are planned for a future phase without a confirmed date, so if you've been waiting on pickleball closer to home, Mountain Ridge isn't there yet.
Where People Are Actually Cooling Off Right Now
While Mountain Ridge finishes filling in, the two spots doing the heavy lifting for hot afternoons are older and smaller. Rosecrest Splash Pad, tucked north of Blackridge Elementary off Rosecrest Lane, is a quieter option with a pavilion, a few tables, and a small playground alongside the spray features. It tends to stay less crowded than the bigger city amenities, which makes it a reasonable pick for families who'd rather skip the wait.
Black Ridge Reservoir, off Ashland Ridge Drive on the south side of the city, is the bigger draw, with a sandy beach, a playground, and open water for wading or paddleboarding. Two dates are worth marking on the calendar before the season closes. Herriman's splash pads across the city run 9 a.m. to 8 p.m. between Memorial Day and Labor Day, which falls on September 7 this year, giving Rosecrest about four more weeks before it shuts down for the season. The $15 all-day parking fee at Black Ridge, which applies on Saturdays, Sundays, and holidays, runs through that same date, September 7. After that, weekend parking is free again, though the swimming season itself will be winding down by then too.
Further west, the city has also been extending trail access along Juniper Trail Drive, adding a new trailhead intended to make it easier to reach the hills trail system without parking on a residential street. It's still in progress, not yet a finished amenity, but it's one more sign that the outdoor side of Herriman keeps growing even as the retail side catches up.
Why This August Feels Different
None of these updates would mean much on their own. A car show is a car show, a splash pad is a splash pad, and a construction sign is a construction sign. What makes this particular month worth paying attention to is that Herriman's two long-running storylines, the outdoor calendar that's always been ahead of schedule and the retail buildout that's always been behind it, are finally close enough in time to watch happen together. By the time the Sunset Series wraps up on September 14, the shell buildings at 13400 South will have had roughly six months since substantial completion to fill in with tenants. Whether Target and Trader Joe's open before or after that final inflatable dash is genuinely an open question right now, but for the first time in two years, it's a question with a realistic answer instead of a rendering.
If you're weighing what a neighborhood like this looks like a year or two out, once the Commons is open and Mountain Ridge is finished filling in, that's a conversation worth having with someone who tracks this market closely. Heather Houston works with buyers and sellers across Herriman and the surrounding Salt Lake Valley, and would be glad to talk through what these changes mean for your own plans. Let's Connect.
