“Through the multi-year strategy to maintain and enhance the lower catchment of Brooklyn Creek, the Town of Comox and its collaborators have provided a working example of understanding the worth of the creekshed, its hydrology, and ecological systems. This effort confirms the need for similar investment in other catchments of the creekshed,” stated Tim Pringle. “The EAP analyses have described what the Town’s residents and key intervenors think the Brooklyn creekshed is worth. The understanding gained will be shared with other local governments.”

At Parksville 2019, Marvin Kamenz elaborated on three building blocks in the evolution of the Town’s incremental process for implementing changes in development practices: lower Brooklyn Corridor, North East Comox, and new areas tributary to the middle Brooklyn Corridor. “The Town of Comox recognizes that ecological services are core municipal services,” stated Marvin Kamenz. “For the middle reach of Brooklyn Creek, we changed the approach to stormwater management in mid-project to focus on the protection and enhancement of the ‘Package of Ecological Services’.”

“The ecological accounting process (EAP) provides metrics that enable communities to appreciate the worth of natural assets. These resources provide numerous public benefits in the form of ecological services,” stated Tim Pringle. “EAP also calculates the dollar value of the land occupied by the natural commons, thus providing a basis for budgeting maintenance and enhancement expenditures. The natural commons has a corollary – the constructed commons.”

“Development of the Ecological Accounting Process (EAP) began in 2015. The EAP vision was first unveiled in Beyond the Guidebook 2015. This was the third in a series that builds on Stormwater Planning: A Guidebook for British Columbia, released by the provincial government in 2002,” states Kim Stephens. “Beyond the Guidebook 2015 introduced the notion of the ‘twin pillars’ – that is, EAP and the Water Balance Methodology – for asset management strategies that achieve the goal of ‘sustainable watershed systems’.”

“EAP offers some insights on the importance of considering the natural commons as systems that residents, property owners and local governments rely on, but understand only to a limited extent,” stated Tim Pringle. “The commons are those resources in the community that are shared by and available to all residents and property owners. From a human settlement point of view, the reality of the commons provides a way to understand the social realities of managing ecological systems. EAP helps communities calculate what ecological services are worth.”

“The ‘worth’ of a creekshed (i.e. small watershed) is defined in terms of a package of ecological services made possible by the hydrology. More specifically, hydrology means the three pathways by which rain reaches the stream and ecological services refers to the benefits that streams provide to us. This includes flood and erosion regulation, nutrient cycling, habitat, groundwater recharge, etc. The way we have historically developed and drained land has disconnected hydrology from ecology,” stated Kim Stephens.

“Green infrastructure can be cheaper and more resilient than gray infrastructure alone—and it can produce substantial benefits beyond what the balance sheets measure,” states Andrew Steer, President and CEO, World Resources Institute. “These nature-based solutions can help us meet the infrastructure investment gap in a cost-effective manner, while lifting up local communities with benefits in their backyards. We’re at a climate inflection point, and in the midst of an infrastructure crisis. Now more than ever, the world must tap into nature’s wealth.”

“The economic return to the community through this project will far outweigh the costs. For example, the restored site will have tremendous potential to absorb floodwaters and provide resiliency to buffer the effects of climate change from more frequent and severe rain storms, sea-level rise, and storm surge events. This will mitigate the flooding-related costs to Courtenay, which have been in the ballpark of $500,000 per event,” stated Tim Ennis.

Bonnie Keeler reviewed 1,200 scientific studies on increasingly popular green infrastructures such as urban forests, parks, rain gardens, and wetlands and found in a recent paper that it’s unclear how well any of them stack up against “gray” solutions like concrete storm sewers and air conditioning. “There is a huge interest in expanding funding for green infrastructures,” she said. “But we don’t have a tool to understand their value.”

“The concept of natural capital and natural assets can be a challenge to integrate effectively into asset management practices. EAP deals with a basic question: what is a creekshed WORTH, now and in future, to the community and various intervenors? The EAP demonstration application process has been a fruitful journey for the project team and collaborators. Along the way, our collective thinking evolved. We broke new ground with EAP. Insights and understanding that we gained are shared in the Primer on the Ecological Accounting Process,” stated Tim Pringle.
