Profile
Diamond Valley is the town created on 1 January 2023 when Black Diamond and Turner Valley amalgamated into a single municipality. It sits on Highway 22, the Cowboy Trail, where the prairie gives way to the foothills, about forty-five minutes south-west of Calgary and minutes from the Kananaskis boundary.
The two former towns retain distinct characters. Turner Valley is where Canada’s first major oil field was discovered in 1914, and the industrial history is still visible in the landscape and the museum sites. Black Diamond carries more of the retail and the main-street activity. The Sheep River runs through both.
New construction here is small in scale. There is no large master-planned community and no volume builder programme of the kind found in Okotoks or High River; what exists is infill, small subdivisions, custom builds on serviced lots and acreage development in the surrounding Foothills County. Buyers come for the setting and the mountain access rather than for selection.
Commute note: Approximate drive to downtown Calgary via Highway 22 and Highway 22X. Okotoks is roughly 20 minutes east. Off-peak roughly 45 minutes, peak roughly 60 minutes.

We separate an operating facility from funded construction, a developer announcement and a long-range plan. A sales map shows intended land uses; it does not guarantee a builder, tenant, school, road, opening date or uninterrupted view. Written information for the exact phase and lot takes priority over this profile.
Diamond Valley is in a limited-availability stage. Remaining opportunities may be tied to one builder, one housing format, a quick possession or a final phase.
Buyer check: Ask for a dated inventory sheet, release map and written lot-hold terms.
Foothills School Division and Christ the Redeemer: Local schools serve the town; confirm the designated school for a specific address.
Buyer check: Run the exact address through both applicable school-board finders before removing conditions.
The profile identifies Kananaskis Country access, Diamond Valley main street, Foothills School Division and Christ the Redeemer, Sheep River valley and pathways, Oilfields General Hospital. Travel times and access should be tested from the exact phase and at the time of day you expect to use them.
Buyer check: Separate open facilities, funded construction and long-range plan symbols on the sales map.
The street beside a lot can change as later phases, collector roads, commercial parcels and multi-family sites are developed. A landscaped sales-centre route may not be the permanent route.
Buyer check: Request the approved phase plan and current land-use map for every parcel beside and behind the lot.

They amalgamated on 1 January 2023 to form the Town of Diamond Valley. The place names remain in everyday use and in addresses, and each former town keeps its own core, but there is now one council, one administration and one set of bylaws. Because the amalgamation is recent, confirm current tax rates, utility rates and service levels directly with the town rather than relying on older figures for either former municipality.
Yes, but not in the way you would in Okotoks or High River. There is no large master-planned community and no showhome parade. What is available is custom construction on serviced town lots, occasional small subdivision phases and acreage building in the surrounding Foothills County. If you want builder selection and a finished community, this is the wrong town; if you want to build in the foothills near Kananaskis, it is one of the best positioned.
Roughly 45 minutes to an hour to downtown Calgary via Highway 22 and Highway 22X, and about 20 minutes east to Okotoks for larger retail. It is a two-lane highway commute through open foothills country, so drive it in winter before you commit.
Diamond Valley is in a limited-availability stage. Remaining opportunities may be tied to one builder, one housing format, a quick possession or a final phase. Ask the developer or builder for a dated inventory sheet before planning around a specific home or possession date.
This profile does not treat a master-plan symbol as an opening commitment. Ask which schools, parks, shops, roads and facilities are open, funded, under construction or still conceptual.
Current town tax and utility rates following the 2023 amalgamation. Flood mapping for the Sheep River and any tributary near the lot. Wildfire exposure and FireSmart requirements, and what they mean for insurance. Designated public and Catholic schools for the specific address (CBE and CCSD school finders), and whether any on-site school is open or only planned. Whether a lot is fully serviced by the town or requires well and septic. Also request the approved plan for neighbouring parcels, because future roads, commercial uses and building heights can affect noise, traffic, privacy and views.
