The BLV Group, a joint venture of three of Calgary’s most experienced sand and gravel pit operators, was awarded a contract by Alberta Infrastructure & Transportation in 2005 to recover an extensive deposit of aggregates underlying Spy Hill lands.
 

The companies in the group are BURNCO Rock Products Ltd., Lafarge Canada Inc. and Volker Stevin Contracting Ltd.The site contains an estimated 130 million tonnes of sand and gravel. The province anticipates keeping 50 million tonnes for public works alone.

​

The site was named for the upcoming Stoney Trail ring road which is anticipated to use a significant amount of gravel from this site and then serve as the primary road network to distribute the gravel to other parts of the city in the future.
