Scottsdale's new Thompson Peak Dog Park keeps a third of its 3.5-acre lawn fenced off on purpose. The reason goes back to a design debate that started three years before the ribbon was cut. That debate still decides which mornings you'll find the gate locked and which lawn your dog will be sent to.
The park sits at 20199 N. 78th Place, near the southwest corner of Hayden Road and Thompson Peak Parkway. It's the closest public off-leash lawn to DC Ranch. It opened with a ribbon-cutting on Friday, Aug. 21, 2026, reported in advance by ABC15 as free and open to everyone. October is its first cool season. It's the first stretch of the year when a midday visit is comfortable, so it's a good time to learn how the place actually works.
The Surface Decision Behind Everything Else
At an open house on April 24, 2023, City of Scottsdale Parks and Recreation staff showed a conceptual plan for a 3.5-acre site with three cells, two open at a time and one closed for maintenance. The DC Ranch community's own update log describes how that meeting went. Most of the discussion was about surfaces. Wood chips and decomposed granite had been used in other cities and were found to need much less downtime than grass.
The park opened as grass. The City now describes it as 3.5 acres of grass with shade canopies, benches and water fountains. The three-cell layout follows from that choice. Grass under constant paw traffic needs time to recover, and the rotating third cell is how the City gives it that time.
Nick Molinari, Senior Director of Parks, Recreation and Human Services, explained the tradeoff at the opening, as Signals AZ reported: "The three-cell design gives dogs plenty of room to exercise while giving our staff the flexibility to maintain the turf and keep the park in great condition." The same report says the park was designed to operate like Chaparral Dog Park, where three separate play areas let one section close now and then while the others stay open.
A Long Wait for a Short Drive
The grass took a while to arrive. Scottsdale voters approved the project in the 2019 bond election. The DC Ranch update log traces the years between that vote and opening day:
- June 2023: The DC Ranch Community Council submitted comments to the City for the community at large, with construction expected to start in 2024.
- April 2024: Fencing went up at the corner, with the entrance planned from Hayden Road and a footbridge to connect the off-leash area to the existing park.
- July 2024: The City estimated completion in summer 2025.
- July 2025: The project was reported as delayed by more than two years and waiting on City staff approval and then the Development Review Board.
- May 2026: The City started construction, scheduled to finish within the year.
- August 2026: Grand opening on Friday, Aug. 21, from 8:30 to 9:30 a.m., with a City Council and Park Commission ribbon-cutting and pup cups from City staff.
The City lists the project budget at $6.1 million, funded by bonds plus General Fund dollars. That's the posted budget, not a final closeout figure. City Manager Greg Caton called the park "another example of delivering on the investments our community asked us to make," according to Signals AZ.
The Week, Read as a Gate Schedule
Because the lawns need regular care, the posted schedule matters as much as the address. The City lists year-round hours of 5:30 a.m. to 10 p.m. and a fixed maintenance window every Monday and Thursday from 8 a.m. to noon. The City's opening announcement says dog parks close during scheduled weekly maintenance for mowing, turf care and other work.
Other Scottsdale dog parks run on different maintenance days, which helps when Thompson Peak is closed:
| Dog park | Weekly maintenance window |
|---|---|
| Thompson Peak | Monday and Thursday, 8 a.m. to noon |
| Horizon | Monday and Thursday, 8 a.m. to noon |
| Chaparral | Tuesday and Friday, 8 a.m. to noon |
| Vista del Camino | No current schedule listed |
Horizon shares Thompson Peak's maintenance days, so it doesn't help on a Monday or Thursday morning. Chaparral, the park Thompson Peak was modeled on, closes on the other two weekday mornings. Dawn visits work every day. The 5:30 a.m. opening comes well before the 8 a.m. maintenance crews on Mondays and Thursdays.
The City hasn't published a calendar showing when each cell rotates out. It also hasn't posted any fall overseeding closure for Thompson Peak or its other dog parks. The weekly windows above are the only fixed closures on the books.
Two Lawns, Sorted by Energy Level
The second effect of the grass schedule is how dogs are sorted. With one cell always resting, only two lawns are open at a time. The City labels them for "Active Dogs" and "Passive Dogs." The City page gives no weight or size cutoff for either area, so the labels describe how a dog plays and leave the call to the owner.
The Rules That Apply Inside the Fence
Thompson Peak follows the same rules as Scottsdale's other dog parks. A few of them matter more at a new park, where many visitors are coming for the first time:
- Licensing and vaccinations: All dogs must be currently licensed and vaccinated. Puppies under four months aren't allowed until they've had both.
- Group limits: No more than four dogs per visitor, and an adult must accompany anyone under 16.
- The exercise area: No food or alcohol, no female dogs in heat, dogs under voice control, and any hole a dog digs should be filled.
- Behavior: Aggressive or antisocial dogs must be removed right away, and dog attacks are reported to Maricopa County Animal Care & Control at 602-506-7387.
- Outside the fence: Dogs must be on a leash no longer than six feet, under Scottsdale Revised Code Chapter 20, Section 20-32.
The full list is on the City of Scottsdale dog parks page, which also notes that the City doesn't supervise the area and that City staff will ask anyone who breaks the rules to leave. The hole-filling rule is the one most tied to the grass. Every dug patch adds to the repair work the rotating cell is there to absorb.
Getting From the Car to the Lawn
The leash rule covers the walk in. The project added parking along Hayden Road, a new restroom building, and a footbridge that links the off-leash area to the rest of Thompson Peak Park. The DC Ranch August 2026 update counts the lot at 100 spaces. The City hasn't published an as-built count to confirm that. No reporting since opening day has covered crowding or parking pressure, so nobody has shown yet how the lot holds up on a cool weekend morning.
The Sculpture at the Fence Line
The park's public art is by Scottsdale artist Shachi Kale. Axios Phoenix described the installed piece as "Woof!", a series of powder-coated aluminum panels with dog-shaped cutouts made by water jet. Kale told Axios the work was inspired by how much her dog, Buzz, loves dog parks. The City's announcement, as carried by Signals AZ, says the panels show dogs, local plant life, the mountain landscape and other elements inspired by the surrounding community. The two accounts give different panel counts.
For a DC Ranch household, a typical outing looks like this: a 5:30 a.m. start any day of the week, a late-morning visit on Tuesdays, Wednesdays, Fridays and weekends, an active or passive cell chosen by the dog's mood, and Chaparral as the backup on Monday and Thursday mornings.
