Few places truly expose the gap between Edmonton’s potential and its land use decisions quite like Rossdale Flats. Immediately below downtown, beside the North Saskatchewan River and within sight of the Legislature, an operating water treatment plant occupies some of the city’s most strategically located land. Its presence raises a question that Edmonton should be prepared to answer: does this remain the best long-term use of an irreplaceable central location?
From an urban land economics perspective, allowing a substantial industrial utility footprint to remain indefinitely - without a transparent assessment of the alternatives - would be a sin against the real estate gods. A serious city with worthwhile potential should regularly examine whether yesterday’s infrastructure decisions still serve tomorrow’s ambitions, particularly where the opportunity extends well beyond the boundaries of a single property.
Rossdale’s industrial history is understandable and undeniable. Water treatment began at the site in 1903, when access to the river and the engineering requirements of a growing settlement shaped infrastructure decisions. Today, the Rossdale EPCOR facility remains one of Edmonton’s two drinking water treatment plants, and the broader EPCOR site also includes electrical substations. Any transition would therefore involve considerably more than clearing a building and offering the land for redevelopment. These facilities provide essential services, and their replacement would require substantial planning and investment. However, the fact that a location served Edmonton well a century ago does not establish that it should retain the same function forever, especially in light of how the City has grown. Infrastructure planning should respond to the changing city around it, including the increasing importance of central land, public access and the relationship between downtown, the southside, and the river valley.
Urban land economics begins with scarcity. Edmonton can expand its boundaries, but it cannot manufacture another central riverfront beside its downtown. Locations combining proximity to employment, natural amenities, heritage and established neighbourhoods are inherently limited. That scarcity creates opportunity cost, which is the value of the best alternative forgone when land remains committed to its existing use. At Rossdale, that cost cannot be measured solely through the expense of operating the plant or the potential proceeds from selling land. It also includes the public spaces, cultural destinations (including indigenous cultural destinations), appropriately located housing and commercial activity that might otherwise become possible. Those alternatives could generate benefits for surrounding neighbourhoods and the wider city over decades. An honest assessment must account for the value Edmonton receives from the current use alongside the value it may be giving up.
The principle of highest and best use provides a disciplined way to examine that trade-off. In real estate analysis, a proposed use must be legally permissible, physically possible, financially feasible and maximally productive. A desirable address does not satisfy those tests by itself, and an attractive architectural rendering certainly does not establish financial feasibility. At Rossdale, alternatives would need to account for flood conditions, heritage protection, archaeological sensitivity, infrastructure requirements and actual market demand. The same discipline should apply to the existing use. Continued utility operation may prove to be the strongest option over a particular planning period, but that conclusion should emerge from an examination of the evidence. A century of operation demonstrates longevity; whether the arrangement remains economically justified requires an assessment of future costs and benefits.
Another important consideration is how different land uses influence the properties and activities around them. Successful urban developments generate value through proximity. Residents support nearby businesses, cultural destinations attract visitors, and welcoming public spaces encourage people to spend more time in an area. Together, those activities can support investment and strengthen the connection between neighbourhoods. An industrial utility delivers an essential regional service, but its contribution to public street life is necessarily and incredibly limited. At Rossdale, this matters more than most areas because the location could play a greater role in connecting downtown with the river valley, building pedestrian connectivity along the river valley and Walterdale bridge, and providing greater cohesion between downtown and the waters edge. The City’s River Crossing initiative already recognises this potential through a vision combining housing, heritage, gathering spaces and improved public access. That work creates a foundation for a wider conversation, although it should not be mistaken for a plan to relocate the operating water treatment plant.
The strongest objection to relocation is also the most obvious: replacement infrastructure could be extraordinarily expensive. Water treatment depends on suitable river access, transmission connections, storage, pumping capacity and reliable operations. Moving facilities elsewhere could introduce environmental impacts, affect other communities and increase costs for ratepayers. Those concerns deserve a rigorous response. They also make the timing of investment decisions particularly important. Money already spent cannot be recovered by retaining a facility indefinitely, while future capital spending represents a choice among competing options. EPCOR’s flood protection work at Rossdale illustrates the continuing investment required to protect essential infrastructure in this location. Flood exposure must therefore form part of any long-term comparison, with the same scrutiny applied to potential redevelopment. The relevant question is which arrangement delivers the greatest overall value while maintaining reliable service.
Rossdale also requires a definition of value that extends beyond development returns. The Flats have longstanding significance to Indigenous peoples and include the Traditional Burial Grounds and Fort Edmonton Cemetery. Any future vision must respect that history and provide for meaningful involvement by Indigenous rights holders in shaping the outcome. Burial protection, cultural recognition and public stewardship should influence what uses are considered appropriate and where development could occur. These responsibilities are fundamental to determining a credible future for the area. A project could perform well financially and still fail Edmonton if it disregarded the significance of the land or compromised the river valley’s public value. The opportunity is to establish a future that brings economic activity, cultural recognition and public access into a coherent plan.
Edmonton should commission and publish a long-term alternatives assessment that brings utility engineering, municipal planning, Indigenous priorities and independent economic analysis together. It should examine continued operation, a smaller utility footprint, phased relocation and opportunities to release portions of the site as assets reach the end of their useful lives. Each option should identify costs, service implications, public benefits and a realistic timeline, allowing future investment decisions to be made with a clear understanding of their consequences. Rossdale helped build Edmonton, and its next chapter deserves the same level of ambition that shaped its original infrastructure. No serious city should allow an inherited industrial footprint on irreplaceable central land to escape that examination. The real estate gods may forgive the original location, but continuing indefinitely without testing a better future would be considered the greatest sin.
