INCORPORATING GREEN INFRASTRUCTURE INTO OUR CITIES: “How can we move from viewing green infrastructure in terms of ‘nice to have’ extras, to putting green infrastructure at the center of how we value and invest in the infrastructure we need for vibrant, resilient cities?” – a question posed by Jan Cassin, Water Initiative Director, Forest Trends Foundation (July 2019)


“Green infrastructure reduces risks to gray infrastructure from hazards such as flooding and wildfire. It improves the performance and reduces the costs of operating gray water infrastructure when the two are integrated. In some cases, green infrastructure can be a more cost-effective alternative than gray. No one is currently bothering to grade our green infrastructure, yet keeping this infrastructure healthy is important to everyone in the US,” stated Jan Cassin.

Truly Sustainable Cities Are All About Balance: “Smart urban growth hailed by global organizations is not always a smart move for nature,” wrote Vitaliy Soloviy in an article posted by Sustainability Times


“Yet the successes of sustainable cities show that progress is possible. Effective planning and urban governance, as well as a focus on livability, are all essential elements of sustainable cities. Emerging sustainable technologies promise a thrilling future. Still, even the most developed sustainable cities of tomorrow will have a few things to learn from ecovillages and slow cities that have already learned to live sustainably in the now,” wrote Vitaliy Soloviy .

REALITY CHECK FOR MAINTAINING THE NATURAL WATER BALANCE IN URBAN AREAS: About 5.5% of developed land in the continental United States is covered by impervious parking lots! – a research finding by US Geological Survey


There were more than 275 million registered motor vehicles in the U.S. in 2018. Accommodating that number of vehicles requires an enormous network of parking lots, the vast majority of which are made of impervious pavement that rainwater cannot infiltrate. Until now, researchers have been unable to gauge the full extent of impervious parking lot coverage in a scientifically sound way. Findings from the model could be valuable for urban planners and watershed managers as they plan new developments or retrofit existing areas where runoff pollution is a major issue, according to James Falcone of the USGS.

Researchers Link Climate Change to Urban and Suburban Stormwater Management: “What we design now is in place for 20 or 30 years, so we should design it with future climate conditions in mind as opposed to what the past rain has looked like,” said Dr. Mitchell Pavao-Zuckerman, University of Maryland


“This work puts emphasis on what’s happening in local upland spaces that has immediate implications for the people who are living in these watersheds for future flood mitigation, but connects this to the broader issues of how increased runoff links to the health of the Chesapeake Bay,” stated Mitchell Pavao-Zuckerman. “It is really the bigger rain events where we are seeing things not work as well, and that’s concerning partly because we know that with climate change these more intense events are going to become more common.”

BREAKING DOWN SILOS: “If asset management for sustainable service delivery is so simple and logical, why are we not getting it?” asks Wally Wells, Executive Director, Asset Management BC (July 2019)


“Different generations have different perspectives because of the way they grew up which formed beliefs and thinking patterns. This message really brings to light that different audiences will resonate with different messages in different ways,” wrote Wally Wells for an article co-authored with Kim Stephens and Cory Stivell. “Good messaging is what provides an opportunity to change a perspective which in turn aspires action. So maybe the question is: Are you considering your different audiences and ‘generational ways of thinking in your messaging process and content?’ If not, why not?”

BROOKLYN CREEK ON VANCOUVER ISLAND: “The asset that we call Brooklyn Creek watershed stands testament to the power of partnerships and the value derived from those relationships,” stated Al Fraser, Town of Comox, in a session on ‘Beacons of Hope’ at the Parksville 2019 Symposium (watch on YouTube)


“My story is both a personal and collective journey in keeping with the partnership theme; and ultimately building and nurturing relationships along the way,” stated Al Fraser, Superintendent of Parks. “When I look at the definition of partnership, and put it into the context of how it applies to the Brooklyn Creek storyline, the word that resonates most with me is participation. The participation that we have seen in Brooklyn Creek, and that continues to grow, is quite staggering. What we see today is truly a natural and remarkable community asset. It is loved and cared for by many.”

MOVING TOWARDS RESTORATIVE LAND DEVELOPMENT: “It is not a sprint. We are in it for the long haul; and we all need to recognize that we are in it for the long haul. I wonder what Ian McHarg would think if he could be with us today, 50 years after he wrote Design with Nature,” stated Bill Derry when he delivered the opening keynote on behalf of Kitsap County’s Chris May, Surface & Stormwater Division Director, at the Parksville 2019 Symposium


The ‘salmon crisis’ in the 1990s was the driver for pioneer research at Washington State University that correlated land use changes with impacts on stream health. The resulting science-based understanding opened the door to the Water Balance approach to rainwater management in BC. “Data are fine, but you must be able to show decision-makers and the public that we are making a difference and being cost-effective with funding,” stated Bill Derry. “You must be able to develop and tell stories. If you can tell stories well, that is how to make the biggest difference.”

ECOLOGICAL ACCOUNTING PROCESS: “One should view EAP as representing one point along a ‘green infrastructure continuum’. It is the latest evolution in an ongoing process in British Columbia that had its genesis in the late 1980s and early 1990s,” stated Tim Pringle, EAP Chair, when providing historical context for green infrastructure ideas and practices


“EAP embodies what has been learned since 1998,” stated Tim Pringle. “EAP uses the word ‘accounting’ in the sense of taking stock and understanding the worth of ecological services as the community uses them. Holding up this mirror reflects opportunities taken or missed and risks avoided or incurred. It asks the question; how well are we doing? This is a social perspective on the natural commons and the constructed commons. Residents and property owners use and expect to use both of these assets to support quality of life and property enjoyment.”

DEMONSTRATION APPLICATION OF ECOLOGICAL ACCOUNTING PROCESS: Busy Place Creek (Sh-hwuykwselu) in the Cowichan Valley, completed July 2018


Like many small creeksheds, Busy Place Creek (Sh-hwuykwselu) lies in more than one authority with jurisdiction within the watershed. Its upland source and discharge to the Koksilah River are in Cowichan Tribes lands, including the Cowichan-Koksilah estuary, which it nourishes. The mid-reach lies in the Cowichan Valley Regional District jurisdiction (CVRD). “Selection of Sh-hwuykwselu as an ‘EAP Demonstration Application’ was made possible by CVRD willingness to participate in a program funded by the governments of Canada and British Columbia,” stated Kim Stephens.

DEMONSTRATION APPLICATION OF ECOLOGICAL ACCOUNTING PROCESS: Brooklyn Creek in the Comox Valley, completed August 2018


“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.”
