FLASHBACK TO 2010 FROM RAIN TO RESOURCE WORKSHOP: “The Water Balance Model is a response to the need to quickly test alternative green infrastructure techniques prior to implementation,” stated Jim Dumont


“The WBM allows the user to quickly establish the existing, or the predevelopment, base line that will become the standard used to measure the performance of future development scenarios during the planning and design of a project. This allows the user to test various methods to establish the easiest and best ways to achieve the most desirable vision of the future for the Site, the Development, or the Watershed,” stated Jim Dumont.

A CALL TO ACTION: “Without integrated and proactive green resilience strategies, cities risk wasting time and money on adaptation projects,” warns Steve Winkelman in a report released by the Adaptation to Climate Change Team (ACT) at Simon Fraser University (Nov 2017)


“Strategically packaging projects for multiple funders and investors can attract more money and accelerate implementation based on policy and investor priorities, such as – critical infrastructure resilience, business continuity, reduced operating and capital costs, disaster prevention, affordable housing, health, and habitat protection,” stated Steve Winkelman.

CASE FOR GREEN INFRASTRUCTURE: “Revitalizing the natural hydrological system can also aid the absorption of floodwaters,” notes Dr. John Jacob, Texas A&M University


US cities situated next to large bodies of water, including Boston, Houston, and Milwaukee, are making plans to build water-absorbent green spaces that also serve as recreational spots – instead of installing more industrial concrete walls – to stem rising floodwaters. “The focus of Community Engagement and Risk Communication is to help Texas coastal communities go beyond emergency response to achieve long-term resilience to hazards,” said Dr. John Jacob.

DESIGN WITH NATURE: “Developing a more thorough understanding of the community’s natural assets aligns with the city’s overall asset management efforts,” stated Courtenay CAO David Allen


“We’re very pleased to have been selected for a natural asset pilot project here in Courtenay, and it puts us on the leading edge nationally for this approach,” noted David Allen. “We’ve already seen the effects of several floods in low-lying areas in recent years, and it makes sense to maximize the potential of our natural environment to reduce the potential impact of these events on residents and businesses.”

GREEN CITY, CLEAN WATERS: Philadelphia is in Year #7 of a 25-year program to create a citywide mosaic of green infrastructure and restore the water balance


Benjamin Franklin, Philadelphia’s favorite son, described his city’s stormwater problem well: By “covering a ground plot with buildings and pavements, which carry off most of the rain and prevent its soaking into the Earth and renewing and purifying the Springs … the water of wells must gradually grow worse, and in time be unfit for use as I find has happened in all old cities.”

FLASHBACK TO 2006: “The Design with Nature Game Show gets workshop participants thinking about real things, on the ground, so that they can begin to see how use of the Water Balance Model will help them,” explained Richard Boase


The Design with Nature Game Show was one of the features of the training workshop hosted by UBC-Okanagan University.“It is fascinating to see how excited and ‘into it’ people get after a few minutes. The irony is that the grand prize is one hour of personal tutoring by me by phone. Just imagine what they would be like if there was a real prize! It just goes to show how important it is to make a computer modeling workshop fun. If people have fun, they will get more out of the day and perhaps some of the philosophical stuff will actually stick,” stated Richard Boase.

The Nature of Cities: “Instead of aiming at control, we must embrace uncertainty and redefine principles of design to acknowledge the complexity of hybrid ecosystems,” stated Marina Alberti, University of Washington


“I suggest that if we are to understand ecosystems in which humans are the key players, we need a paradigm shift in the way we study these ecosystems,” wrote Marina Alberti. “As ecosystems are increasingly dominated by human action, they move toward a new set of feedback mechanisms. Their state is unstable. We can drive them to collapse or we can consciously steer them toward outcomes we desire.”

Green Infrastructure & A Tale of Two American Cities: Philadelphia and Chicago


“Instead of expanding our infrastructure, we put together a plan to price, value, reuse, recycle, infiltrate, transpire or otherwise manage, every drop of rainwater we could. We started to invent the millions of ways to reduce the amount of rainwater that arrived at our sewer inlets. The goal was to consider rainwater as a commodity and a resource—if it enters a sewer drain it becomes a costly waste product,” explained Howard Neukrug. “There is no single formula for success—and we still don’t know whether ultimately we will succeed.”

Reflections on Balancing Green & Grey: “The smart thing is to work with nature and learn as much as we can from it,” observed Torgny Holmgren, Executive Director, Stockholm International Water Institute


“The relationship between humans and the rest of nature is not always easy. We have entered the Anthropocene – an era in which our species has emerged as a major force of nature,” stated Torgny Holgren. “This is particularly visible in relation to water, where human interventions occur throughout the hydrological cycle: Change in land use alters evaporation which in turn can change atmospheric movements of moisture and cause droughts or floods in distant river basins.”

Los Angeles County has a bold plan to use green infrastructure to supplement water supply


The county is currently developing a plan to meet 20 percent of L.A.’s current demand. “We get a lot of our water from outside of Los Angeles, from northern California, Colorado, and it is getting more and more expensive,” said Dr. J.R. DeShazo. “It’s getting less reliable, and the water quality from some of those external supplies is getting worse.” Advocates hope to build support for green infrastructure designed to capture and store a largely untapped resource that could help quench the county’s constant demand for water – and provide multiple benefits for L.A.’s communities.
