Heritage resources include: “buildings, bridges, engineering works and other structures; cultural landscapes such as historic parks, gardens or streetscapes; culturally significant areas, including indigenous traditional use areas and sites with archaeological or palaeological significance. These can be managed by municipal, provincial or federal authorities.” (City of Calgary). Buildings, landscapes and features that are at least 25 years-old and have standalone significance, may qualify for listing on the City’s growing inventory of historic resources. They are evaluated by Heritage Calgary, a civic partner, according to a Council-approved evaluation system. When listed on the inventory, historic resources are recognized for their heritage significance and are referred to as heritage sites. Historic resources are not subject to development or demolition restrictions unless designated (legally protected) in cooperation with a property owner.
