NESTED CONCEPTS (GRAPHIC): How do we change what we are doing on and to the landscape? Everything comes down to one question: What is the number for the line item in a local government annual budget for community investment in maintenance and management of stream systems?


“The idea that nature provides “ecological services” is not intuitively understood by the public, elected representatives and asset managers. Because the concept is abstract, it requires a leap of faith for buy-in at an operational level in local government where numbers matter. This challenge accentuates the need for effective communication tools. The Nested Concepts graphic helps local governments move past the rhetoric and focus their attention on achieving desired outcomes through a sustained and affordable investment in restoration of streamside protection zones,” stated Kim Stephens.

CASCADING CONCEPTS (GRAPHIC): “Visualize a Monday night meeting of a municipal council and reflect on how councils make decisions. Their mindset is all about what happens at the parcel scale. This is the driver for creating an over-arching mind-map to explain the Ecological Accounting Process in terms they understand,” stated Tim Pringle, EAP Chair


“It is amazing that we have been able to produce a methodology that defines what a stream is, can find the value of the stream using impartial BC Assessment data, and add to that a riparian assessment that looks at the 30m zone and a further 200m upland area to evaluate the water balance condition and what is happening to water pathways,” stated Tim Pringle. “How concepts are explained is crucial. What is easily understood and measured gets implemented. The use of cascading concepts as a mind map helps us cut through the rhetoric to provide audiences with meaningful context and content.”

TWIN PILLARS OF STREAM SYSTEM INTEGRITY (GRAPHIC): “There are many factors that influence stream degradation. There is not a single smoking gun. Sure, impervious area is the main culprit. But you can trash a stream just as badly by deforestation of the riparian zone as you can by paving over the headwaters with a mall,” stated Dr. Chris May, a Washington State local government leader


“We figured out that you can do all you want with stormwater runoff to restore the water balance, but you still are not going to restore the aquatic resources to where they need to be unless you actually jump into the streams and riparian areas and do restoration there. So that is what I did. My leadership position as Division Director at Kitsap County allowed me to put science into practice. We learned through experience that you cannot do just stormwater or restoration. You have to do both. Also, working at multiple scales and multiple levels is really key,” stated Chris May.

Green Infrastructure Community-of-Practice is the online home for EAP, the Ecological Accounting Process, which is an initiative of the Partnership for Water Sustainability for British Columbia


“Commencing with a launch announcement by the BC Minister of Environment in 2005, this community-of-practice has served an important function as the home for green infrastructure in British Columbia. Originally created to support the work of the Green Infrastructure Partnership, the community-of-practice now has a dual focus in supporting two interconnected initiatives, that is: EAP, the Ecological Accounting Process: and Asset Management for Sustainable Service Delivery in BC, which is led by Asset Management BC,” stated Mike Tanner, Waterbucket Chair.

DEMONSTRATION APPLICATIONS: A 6-year program of applied research between 2016 and 2022 to test, refine and mainstream the methodology and metrics for EAP, the Ecological Accounting Process, a “made in BC” strategy for community investment in stream systems and other natural commons


“Thirteen local governments in five sub-regions of the Georgia Basin / Salish Sea Bioregion participated in the EAP program. The sequencing of the 9 case studies proved consequential and sometimes game changing. While the methodology and metrics are universal, each situation is unique. Understanding what each partner needed as an outcome from the project became a critical consideration in the building blocks process. EAP evolved as one big idea led to the next one. The 19 big ideas are transformative in their implications for why and how local governments would implement Sustainable Drainage Service Delivery,” stated Kim Stephens,

DEMONSTRATION APPLICATION OF ECOLOGICAL ACCOUNTING PROCESS: Bertrand Creek in the Township of Langley, completed in 2022


“The Langley Ecological Services Initiative is about compensating rural parcel owners who are willing to set aside areas of their land to protect and/or enhance riparian and woodland assets. The Township posed the question: Is ‘payment for ecological services’ part of an Asset Management Strategy? The Township turned to EAP for a method to find the financial value as well as the worth of these streamside assets. This provides the Township and the community with a defensible asset management approach that is about the asset that will be tied up for the ecological purposes,” stated Melisa Gunn.

DEMONSTRATION APPLICATION OF ECOLOGICAL ACCOUNTING PROCESS: Bings / Menzies Creek in the Municipality of North Cowichan, completed in 2022


The protected stream corridor for Bings Creek is the central feature around which urban development has taken place in this century. Strata parcel development is a dominant land use. It replaces native vegetation from 60% or more of the parcel area with hard (impervious) surfaces and alters what remains. This scale of landscape alteration has a material impact because it short-circuits pathways by which water would naturally reach the Bings Creek channel. “This conclusion is validated by the streamflow history as recorded by the Bings Creek gauging station,” stated Dave Preikshot.

DEMONSTRATION APPLICATION OF ECOLOGICAL ACCOUNTING PROCESS: Saratoga Miracle Beach in the Comox Valley Regional District, completed in 2022


“The Saratoga Miracle Beach study area within the Comox Valley Regional District (CVRD) is defined by its water assets. The presence of wetlands differentiates the Saratoga Miracle Beach EAP Project from other EAP case studies and added a new dimension to the EAP analysis. The CVRD anticipates using this work, together with the Master Drainage Plan and flood mapping work, to inform the development of new regulatory tools and to assist in communicating the value of these natural assets to the public during future community engagement,” stated Darry Monteith.

HOW WE CHANGE WHAT WE ARE DOING ON THE LANDSCAPE: Synthesis Report on EAP, the Ecological Accounting Process, a BC Strategy for Community Investment in Stream Systems (released by the Partnership for Water Sustainability, June 2022)


“In 2016, the Partnership embarked upon a 6-year program of applied research to evolve EAP through a 3-stage building blocks process of testing, refining, and mainstreaming the methodology and metrics for financial valuation of stream systems. The program involved 9 case studies and 13 local governments and yielded 19 “big ideas” or foundational concepts. The program goal was to answer the question, how much should communities budget each year for maintenance and management of stream systems,” stated Tim Pringle.

ASSET MANAGEMENT FOR SUSTAINABLE SERVICE DELIVERY: “Provide a consistent, reliable level of service that saves $millions over time and builds community resilience in an increasingly risky climate,” wrote Kim Fowler of the Regional District of Nanaimo (Winter 2023 issue of Asset Management BC Newsletter)


“How do you do a budget if you don’t know what assets you have, their condition and when they need to be replaced? Climate change is increasing risk by damaging assets. And while the focus of your asset management plan should be integration with your long-term capital budget, don’t overlook the ‘master asset management plan’, otherwise known as your Official Community Plan (OCP). They set the locations and standards of future growth in your community, and as a result, set the core infrastructure needs and their associated costs,” stated Kim Fowler.
