Community overview
Solstice Foothills was launched as Rio 1900 and later rebranded
Harvard Investments confirms this is the same long-planned Goodyear development that was previously processed publicly as Rio 1900 and earlier known as King Ranch. The new name signals a more defined identity, but the land-planning history still matters because many public references remain tied to the earlier project names.
The project is being positioned as a future desert community with trail connectivity, a walkable commercial core, outdoor-focused amenities, and a distinct market position from neighboring Estrella.
Why this page matters
It separates verified public information from the details that are still pending so buyers do not mistake planning vision for active inventory.

Solstice Foothills planning case moves forward publicly
City materials and coverage describe a rezone from King Ranch PAD to Solstice Foothills PAD plus a minor General Plan amendment involving 31 acres.
Rebrand to Solstice Foothills
Harvard formally introduces the Solstice Foothills name and frames it as a new chapter for the same long-evolving Goodyear land holding.
Infrastructure first, homes later

Amenities & plan vision
What the future community is planned to include
Trails and outdoor living
Harvard's vision centers on trail connectivity, the Gila River corridor, and outdoor wellness. Hill Companies says Solstice Foothills is expected to help establish standards for the El Rio Trail in the West Valley.
Parks and open space
Solstice Foothills planning coverage references a 30-acre public community park, five neighborhood parks, local pocket parks, and a 3-mile El Rio Linear Park.
Commercial core
Harvard says the vision includes a walkable commercial core intended to support convenience and neighborhood connection.
Water-conscious design
Developer messaging repeatedly emphasizes Sonoran-desert responsiveness, water efficiency, restrained turf use, and shared amenities designed to reduce private water-intensive features.
Important: these are planned features from developer and planning sources, not a promise that every amenity is already built or currently open.
Need a buyer-side strategy?
Track the community early instead of waiting for a builder sales pitch
Cinda Rose helps buyers monitor future community releases, compare nearby new-construction options, and get positioned before pricing, lot releases, and builder incentives start moving.
Schools
School district information is still planning-stage
What city documents say
Goodyear planning materials reference coordination with Liberty Elementary School District and Buckeye Union High School District, tied back to earlier King Ranch planning agreements.
Future school sites
One city attachment says the Solstice Foothills concept proposed two elementary schools within the community boundaries.
What buyers should assume for now
Final attendance boundaries are to be confirmed. Buyers should verify school assignments directly before contract, during the sales process, and again before close if the project is still years from delivery.
Why representation matters
Why buyers should bring their own agent to a builder sales office
The builder's onsite team represents the builder. A strong buyer's agent changes the experience by helping you compare options objectively, protect your leverage, and stay informed from contract through completion.
Builder relationships without losing your own advocate
Cinda Rose works with West Valley builders and understands how builder sales teams operate, but her role is to represent you — not the builder. That means helping you compare communities, read incentive offers carefully, and avoid rushing into a contract on the first visit.
Contract, incentive, and upgrade guidance
Builder contracts are detailed, builder-favoring documents. Cinda helps buyers understand timelines, upgrade decisions, financing pressure points, warranty language, and which incentives are real value versus marketing noise.
Third-party inspections at key construction milestones
Cinda encourages independent inspections at meaningful stages such as pre-drywall, final phase, and other milestone points appropriate to the builder's process. That extra layer of oversight matters in new construction just as much as it does in resale.
Ongoing build updates while your home is being completed
For out-of-area and busy buyers, Cinda stays engaged during construction with regular check-ins, phase-by-phase updates, and photos or videos from the site when possible, so clients can follow progress from contract through walkthrough and closing.
Build-time expectations
What to expect on timing
Because Solstice Foothills is still in the planning stage, there is no community-specific builder timeline yet. For buyer education, a typical production new build in the West Valley is often around six months, but that can stretch longer depending on lot release timing, plan complexity, options, permits, utilities, weather, and builder workload.
For this particular community, the bigger timing question is not just construction speed — it is when active sales begin. Current verified sources point to infrastructure first and homes later, with first move-ins expected closer to 2030 than today.

FAQ
Questions buyers are likely to ask about Solstice Foothills
Was Solstice Foothills previously known by another name?
Yes. Harvard Investments says Solstice Foothills is the current name for the same Goodyear master-planned community previously known as King Ranch.
Is Solstice Foothills selling yet?
Not based on currently verified public sources. No official sales site, builder release, model opening, or pricing sheet was found during this research.
Who is building homes there?
That is still to be confirmed. The developer has indicated the community may feature some of the same builders found in Estrella plus specialty builders, but no builder names are officially published yet.
What amenities are planned?
Public sources point to parks, trails, a Gila River / El Rio trail connection, a walkable commercial core, outdoor-oriented amenities, and a planned resort-style community center concept. These are planning-stage features and should be treated as future plans until delivered.
What schools would serve the community?
City documents reference Liberty Elementary School District and Buckeye Union High School District planning coordination, plus two proposed elementary school sites, but final school assignments are still to be confirmed.
How long will it take before buyers can move in?
Current verified reporting points to infrastructure activity before homebuilding, with first homes expected around 2030. Once builders begin selling, an individual home's construction timeline will still depend on plan, lot, builder, and options.
Why should I bring my own agent if I visit a builder sales office?
The builder's sales staff works for the builder. Bringing your own agent gives you an advocate for contract review, incentives, lot and plan comparison, inspections, communication, and issue escalation throughout the build.
Where is Solstice Foothills located and how is the commute to Phoenix?
Solstice Foothills is in South Goodyear, Arizona, between Estrella Parkway and 187th Avenue with the Gila River as its northern edge, adjacent to the Estrella community. Regional access is tied to Estrella Parkway, Cotton Road, Interstate 10, and the future SR 30 / Loop 303 interchange.
Are there HOA or CFD fees at Solstice Foothills?
HOA dues, community facilities district (CFD) assessments, and tax disclosures have not been published yet. Because the community is still in the planning stage, buyers should expect these details to be released with the builder sales launch and should verify them before contract.
Can I reserve a lot or get on a list for Solstice Foothills now?
No public lot releases, reservation lists, or VIP programs have been announced. Cinda Rose tracks land planning, builder announcements, and phase releases for buyers who want early notice, and can help compare Solstice Foothills against Goodyear communities that are already selling today.
