What is Winchester Hills, Utah like?

Winchester Hills is an unincorporated acre-lot community roughly six miles north of the center of St. George, reached from two exits on State Highway 18.

Unusually for a neighborhood this size, Washington County has published a community general plan for it, which means several things on this page come from the county rather than from a listing. The plan was adopted in 2011, so treat it as authoritative about the development’s history and cautious about anything current.

The county records a drainage problem from the start

This is the thing a buyer would not otherwise hear, and it comes straight from the county’s plan.

The development began in 1980, with the first of nine phases recorded that April. At the time the county did not require paved roads — the developers paved them anyway, as a selling point, which the plan notes worked. But the county also did not require curb and gutter, and the plan says plainly that curb and gutter alongside the paved streets “would have eliminated many of the flooding problems that have existed since the development began.”

The same plan calls it, overall, a very desirable development. Both things are true, and that is exactly how I would want it described.

What to do with that: on any specific lot here, ask where water goes in a storm. Look at the grade, look at where the road sheds, and ask the neighbors — they will know, because this is a forty-five-year-old pattern rather than a hypothetical. Whether you need flood insurance in Washington County is the next question, and the answer is address-specific rather than community-wide.

An inspection should look at drainage, grading and any evidence of past water intrusion. What a home inspection should look for in southern Utah is the baseline.

Acre lots, and nearly built out

The plan describes nine phases and 347 lots of approximately one acre, with some larger lots since divided, bringing it to somewhat more than 366 lots.

It also says something buyers rarely get told: aside from some adjacent trust land that could potentially be developed, Winchester Hills is very near build-out.

That is because of what surrounds it. The plan gives the boundaries as St. George on the south, Bureau of Land Management land on the east, Institutional Trust Land on the north, and Snow Canyon State Park plus private land within St. George on the west.

Being hemmed in by public land is the most valuable thing about this community and nobody markets it. It means the open ground around you is not a future subdivision in most directions. In a county growing as fast as this one, that is rare and it is worth real money — and it is a different proposition from buying next to private land that happens to be empty today.

Whether St. George is growing too fast is the context that makes this matter.

The soil and the aquifer

The plan describes the soil as essentially a blow sand layer sitting above the Navajo Sandstone aquifer, from which most of the county’s culinary water is produced.

Two reasons that matters to a buyer.

Blow sand behaves differently from the clay soils elsewhere in the county. Whether the soil in St. George is bad for foundations covers the problem soils here, and the useful point is that soil is a per-lot question rather than a city-wide one. Ask about the soil report.

Sitting above the county’s main culinary aquifer is relevant to how waste water is handled on acre lots, and to why the county cares about what happens on the surface here. Ask what your specific property is on for water and sewer, and get it in writing rather than assuming. Whether there is enough water in southern Utah is the wider backdrop.

Steep ground to the north

The plan notes that most of the land to the north and north-east is steep hillside, including a bluff area on the trust land.

If you are looking at a lot against that ground, the usual hillside questions apply — drainage from above, slope stability, and retaining structures. What to check before buying a house on a hillside in this county covers them.

Unincorporated means county, not city

No city government. Washington County rules, county permitting, county services.

Your building permit comes from the county, and what you may do with an acre — a shop, animals, a second dwelling — is a county zoning question. Ask before you buy if any of that is part of the plan.

Emergency response comes from a district rather than a city department. On acre lots north of the city that is worth asking about, because it affects insurance as well as response.

Roads are paved, which the plan credits to the original developers rather than to any requirement. Ask who maintains them now and what that costs.

Who it suits

Buyers who want an acre, genuine space between houses, and the near-certainty that public land is not going to become a subdivision.

People who want to be close to Snow Canyon State Park. That is the amenity here, and it is a better one than any clubhouse.

Anyone comfortable with county rather than city services, and who will do the drainage homework on the specific lot.

Buyers who want 1990s-era housing stock on real ground rather than new construction on a small lot.

Who it does not

Anyone who wants to be in town. This is a drive from St. George for everything, up Highway 18.

Anyone who wants an amenity set. There is none — the state park and the space are the amenities.

Anyone who skips the drainage question. The county has put it in writing; ignoring it would be a choice.

Anyone wanting new construction. The community is near build-out, so what exists is largely what there will be.

What I actually see

Buyers who come for the acre and the quiet and never read the county’s plan, which is free and says more than any listing.

The flooding line in particular is the kind of thing that only appears in a document nobody opens. It does not mean every lot floods — it means the development was built without the drainage infrastructure that would have prevented it, and that the county has been aware of the consequence for decades. On a specific lot that is answerable, and the answer should affect what you offer.

The other thing I see is people underestimating the drive. An acre six miles north of town up a state highway is lovely and it is not convenient, and those two facts do not cancel out.

What to do next

Read Washington County’s community general plan for Winchester Hills — it is public and it is short. Then on any lot you like, ask where the water goes in a storm, get the soil position, and confirm with the county what you may build.

I am Kelsey Earl, a Realtor with Keller Williams South Valley, and on an acre lot I would rather spend an afternoon on drainage than a decade on a wet basement. Send me a parcel in Winchester Hills and we will start with the grade.

Nearby

Dammeron Valley further north is the other unincorporated acreage option, on water shares and septic rather than near the city. Foremaster Ridge is the larger-lot option inside St. George, and Kayenta in Ivins — written up as a post — is where people go for space with architecture attached.

Everything is on the neighborhoods page.

Note: The development history, phase and lot counts, boundaries, soil description, build-out assessment and the drainage observation above are taken from the Washington County General Plan for the Community of Winchester Hills, adopted in 2011 — so they are authoritative about the development’s history and fifteen years old as a description of current conditions. Lot sizes, home sizes and prices circulating on listing sites are not from the county and no figures appear here. Confirm current zoning, utilities and road maintenance with Washington County.
