Boundary: Assessed values are the City’s assessment-roll figures for taxation and are not sale prices, asking rents, vacancy or availability; Alberta does not publish transaction prices. LiDAR heights are roof-surface elevations above the lowest ground point at the building perimeter and can differ from architectural heights. Storey equivalents are derived at 3.9 m per storey and are not floor counts. Distances are straight-line. Permit descriptions are the City’s records at retrieval and do not establish current use, tenancy or availability. Read the methodology.
