Walk the south loop at Vistoso Trails Nature Preserve on a July morning and the site still reads like what it was: fairways gone to grassland, a paved cart path threading past sand traps softened into low mounds, an empty pond bed near Vistoso Highlands Drive. Regulars know the rhythm. Dawn-to-dusk gates, three underpasses, two accessible restrooms, and a 6.2-mile eight-foot concrete loop that has looked essentially the same since the Town of Oro Valley took ownership in 2022.
That rhythm changes this year. Not because a new design was unveiled, but because a specific funding stack finally lined up. The preserve's 2026 breakthrough is a story about money and sequencing, not landscape architecture, and it explains why the pond and the ADA loop are being built together instead of one after the other.
The thesis, in one sentence
For four years the preserve has been a "coming soon" sign. What changes in 2026 is not the design ambition, which has been public since 2024, but the fact that three separate funding sources converged in a way that forces construction to start now, together, on features that would otherwise have been sequenced across a decade.
What is actually breaking ground
The Kimley-Horn design concept, led by senior project manager Rebecca Field, cleared council review last September. The scope residents will see under construction this year:
- A 2.5-acre irrigation pond near Vistoso Highlands Drive, regraded and raised from its current depth through earthwork.
- An ADA-compliant soft trail circling the pond, tied into the existing concrete loop.
- A memorial space with bike racks and benches near the pond, funded by a resident's estate gift.
- Formalized soft pathways over the routes people already walk, rather than new cuts through the desert.
- Native revegetation irrigated off the pond's water-harvesting circulation.
- Repairs to cracked and heaved sections of the existing concrete loop, plus new safety signage.
Field's team targeted the final pond design for April 2026 while working to pull it forward to February. Councilmember Mary Murphy publicly flagged the one-month slip at the September meeting; Vice Mayor Melanie Barrett pressed staff to keep this year's focus on the pond itself rather than the peripheral amenities. Construction is anticipated to begin in 2026 per Parks and Recreation Director Roslyn Epting, and the ADA trail will be built in coordination with the larger Desert Ecosystem Restoration Project rather than as a follow-on phase.
The funding stack that made "together" possible
This is the part that matters to anyone who has watched the site sit still since 2022.
The Town of Oro Valley secured a $144,500 grant from Arizona State Parks through the Recreational Trails and Off-Highway Vehicle Recreation programs. It pays for pathway repairs, new safety signage, and the ADA trail around the pond. The town's match is roughly $9,000, which puts the local contribution at 5.7% of a $153,000-plus package. That ratio is why the ADA scope moved from "future phase" to "built alongside the pond." A grant that specific, at that leverage, does not sit on a shelf.
The second source is private. A resident donated a home in memory of her brother, an avid cyclist. Once sold, the proceeds are earmarked for shaded seating, water fountains, the memorial area near the pond, decomposed-granite trail shoulders, and additional desert planting. Epting has confirmed the gift and its intended use. Field's presentation to council specifically named the memorial as resident-funded.
The third source is the town's own capital planning, which is why the pond gets built as a water-harvesting feature rather than a decorative one. Circulation partly relies on irrigation return from nearby landscaping. Charles Stack, a water-conservation engineer who lives in Oro Valley, has raised concerns at council about reclaimed and potable water use for pond fill. The design responds by using the pond to irrigate the surrounding native plantings, not the other way around, with Field citing the successful Canoe Ranch water-harvesting precedent.
Read together, the three sources answer a question residents have been asking since 2022. Why now, and why all at once? Because the state grant is ADA-specific, the private gift is amenity-specific, and the town's capital line is pond-specific. Sequencing them would forfeit the grant match and delay the estate gift's stated purpose. Building them in one construction window is the only way the money works.
What opened around the loop this year
The preserve is one anchor of a resident's week. The Rancho Vistoso Boulevard and Tangerine Road spine is the other. January 2026 alone brought 22 new business licenses in Oro Valley, and a handful of them changed the map for people who already live in the neighborhood:
| Opened / Certified | Business | Address |
|---|---|---|
| Jan. 28, 2026 | Oro Valley Coffee Roasters retail | 1551 E. Tangerine Rd. |
| Jan. 20, 2026 | The Motive AZ | 2530 E. Vistoso Commerce Loop |
| January 2026 CofO | Copper Center (Sun City Oro Valley Community Association) | 1119 E. Rancho Vistoso Blvd. |
| January 2026 CofO | Smashburger 1801 | 7625 N. Oracle Rd., Unit 145 |
| January 2026 CofO | Solana Pilates | 10355 N. La Cañada Dr., Suite 117 |
| January 2026 CofO | Kinghorn Law | Financial |
None of these are destination openings. They matter because they finish the everyday circuit. A Rancho Vistoso resident walking the Woodshade Linear Trail out to Rancho Vistoso Boulevard can now finish at Oro Valley Coffee Roasters on Tangerine instead of driving to Oracle for coffee. Sun City residents have a new indoor Community Association gathering space at the Copper Center on Rancho Vistoso Boulevard. The existing anchors residents already fold into that loop, Sahuaro Cafe in the Safeway Plaza at First and Tangerine and The Views Restaurant inside Sun City at 1555 E. Rancho Vistoso Blvd., now sit inside a denser cluster of destinations rather than isolated stops.
Where the walk reroutes this summer
Two projects will interrupt the usual patterns before the preserve construction fencing goes up.
The Vistoso Community Association begins a perimeter-wall repainting project on June 15, 2026, covering several neighborhoods and the tennis court fence at Hohokam Park. Expect staging, crew vehicles, and temporary tarping along walk-friendly stretches of Rancho Vistoso Boulevard.
The Oro Valley Water Utility's Northwest Recharge, Recovery and Delivery System is installing several miles of 20-inch transmission main, with KE&G Contracting scheduled from September 2025 through August 2026. The utility docket also lists Rancho Vistoso booster upgrades. Trench work and traffic control on any of the north-south feeder streets can shift a familiar walk by a block or two for weeks at a time.
Fiber installation from Ripple Fiber and Wyyerd Fiber, authorized by the town, continues in parallel. Not disruptive at the scale of a waterline, but visible on lawn edges throughout the year.
A revised weekly loop, drawn from the research
For a resident already dialed into the neighborhood, the practical map for the rest of 2026 looks like this:
- Morning walk on the preserve's south loop out of the 945 W. Vistoso Highlands Dr. temporary parking, with the understanding that construction staging will appear near the pond bed once the final design lands.
- Coffee at Oro Valley Coffee Roasters on Tangerine, or breakfast at Sahuaro Cafe until 2 p.m.
- Errands routed to account for repainting crews and waterline trenching along the Rancho Vistoso Boulevard corridor.
- Evening stroll on Woodshade Linear Trail or into Wildlife Ridge, Hohokam, or Honey Bee Canyon parks.
- Watch the Preserve Vistoso mailing list and Town of Oro Valley council agendas for the Kimley-Horn construction start notice.
The field guide to preserve flora and fauna, prepared by resident Jake Smith and published through Preserve Vistoso, is still the best companion document for anyone using the loop more than once a week. It becomes more useful, not less, as revegetation begins and new species establish along the pond edge.
What this year is really about
Residents have watched this preserve site since the golf course closed in 2018 and since Friends of Vistoso Trails and The Conservation Fund shepherded the 2022 donation to the town. What 2026 confirms is that a preserve of this scale, 202 acres inside a master-planned community, does not get restored on a single funding source. It gets restored when a state grant, an estate gift, and a municipal capital line all argue for the same construction window.
