Diamond Valley is a town in the Calgary Metropolitan Region of Alberta, Canada within Foothills County. It is at the intersection of Highway 22 (Cowboy Trail) and Highway 7. It was established through the provincially approved amalgamation of the former towns of Black Diamond and Turner Valley on January 1, 2023.
Black Diamond and Turner Valley incorporated as villages on May 8, 1929 and February 23, 1930 respectively.[2] After nearly 26 years as a village, Black Diamond incorporated as a town on January 1, 1956.[2] Turner Valley incorporated as a town on September 1, 1977 after 47 years of village status.[2]
The thought of amalgamating the towns of Black Diamond and Turner Valley first surfaced in the mid-1980s. Turner Valley withdrew from the discussions after Alberta Municipal Affairs completed a feasibility report on the amalgamation in 1986.[3]
The possibility resurfaced in 2006 when the towns initiated discussions on a possible amalgamation of the two municipalities.[4] The discussions culminated in a plebiscite held on October 15, 2007, concurrently with their municipal elections, in which the question asked of voters was "Do you support an amalgamation of the Town of Black Diamond and the Town of Turner Valley to form one municipality?"[5] The results of the plebiscite were 66% of Turner Valley voters were in favour of amalgamation, while 71% of Black Diamond voters were against amalgamation.[5]
A third amalgamation investigation began in early 2016 through a joint request of Black Diamond and Turner Valley for a provincial grant to undertake a feasibility study.[6] Following negotiations and engagement, the two town councils decided to proceed with an amalgamation application in September 2021.[7] The name of the amalgamated municipality was proposed to be the Town of Diamond Valley.[7] Among over 200 name suggestions, Diamond Valley received the majority of responses in a survey of three shortlisted suggestions; the other two being Sheep River and Black Valley.[7] The proposed effective date of the amalgamation was January 1, 2023.[8] On May 25, 2022, the Government of Alberta approved the amalgamation application with the municipality name and effective date as originally proposed.[9] On November 28, 2022, both towns voted for their new town's first mayor and council with Turner Valley's current mayor Barry Crane being elected Diamond Valley's first mayor.[10]
