FLASHBACK TO 2003: “Regional District of Nanaimo’s ‘Drinking Water & Watershed Protection Program’ had its genesis in British Columbia’s Stormwater Guidebook process,” recalls John Finnie
Note to Reader:
In 2002, the provincial government released Stormwater Planning: A Guidebook for British Columbia. This established a new direction for urban hydrology and drainage engineering. Introduction of the Water Balance Methodology enabled the setting of performance targets for rainfall capture, runoff control and groundwater recharge:
If we manage the runoff volume, and if we mimic the natural flow pattern in streams, then we can… prevent increased stream erosion, prevent increased risk of flooding, and protect aquatic habitat.
One of the early articles written about the Guidebook was by Geoff Gilliard. In 2003, he described how the work of two local governments had provided case study content for the Guidebook. The contribution by the Regional District of Nanaimo (RDN) is described below.
Eliminate the Root Cause of Impacts
“For most of the last century, land development in our communities has followed the same general pattern: clear the trees, put in roads and subdivisions, and direct the runoff into the nearest stream or storm sewer. But pipes carrying runoff speed the flow of stormwater, often creating erosion and downstream flooding,” wrote Geoff Gilliard in an article published in Spring 2003.
“Many local governments are under pressure to protect streamside property that is threatened by stormwater development. The new Stormwater Planning Guidebook for BC gives municipal land planners and engineers a tool to help make land development compatible with stream protection.”
“The Guidebook offers a new approach to stormwater management that eliminates the root cause of ecological and property impacts by designing for the complete spectrum of rainfall events.”
“The Stormwater Planning Guidebook uses a series of case studies to illustrate solutions to stormater problems.”

Setting Priorities for Early Action
The Regional District of Nanaimo (RDN) undertook a watershed assessment process that provided the Guidebook process with a feedback loop. The RDN case study experience was then incorporated in the Guidebook as two chapters:
- Chapter 4: Policies for Integration of Land Use Planning and Stormwater Management
- Chapter 5: Setting Priorities for Early Action
The RDN was the demonstration region for applying a Knowledge-Based Approach and testing a methodology for prioritizing action that focuses on low-cost results by getting the right people together in working sessions.
“If the right people with the right knowledge are involved at the start, a knowledge-based approach will be both time-efficient and cost-effective,” stated John Finnie in 2002. In his capacity as General Manager of Environmental Services for the RDN, he led the RDN process and was a member of the Stormwater Guidebook Steering Committee.
“To support the Guidebook process, the RDN took the lead in developing and applying the At-Risk Methodology. Through a workshop process, we integrated knowledge from each of the engineering, planning and ecological perspectives. The process identified 12 priority catchment as candidate areas for future integrated stormwater planning initiatives.”
“We may have some challenges in selling the concepts to some stakeholders. We are trying to change the nature of the way people have done things for years. So we have to provide opportunities for people to understand what we are trying to do and why.”
RDN Drinking Water & Watershed Protection Program
“In February 2003, a staff report to the Board crystallized the Action for Water vision,” recalled John Finnie in the RDN section of Beyond the Guidebook 2015. “The 2003 report is a valuable historical document, and built on what the RDN had initiated through participation in the Guidebook development process. Not only did it consolidate various directives, it identified a strategy (and associated implications) for moving forward incrementally with the regional service area for the Drinking Water & Watershed Protection Program.
“In 2008, and as the outcome of a successful referendum, the RDN became the first regional government to create a drinking water and watershed protection service area with taxation authority in an electoral area. This was the culmination of a 6-year effort. In 2012, the service area was expanded to include the municipalities within the regional district and they became active participants in the watershed function.
“Looking back, the seeds for watershed-based action in the RDN were sown in the Guidebook process which unfolded during 2001 and 2002. For this reason, we say that the RDN’s‘Drinking Water & Watershed Protection Program’ had its genesis in Guidebook process, and those seeds have flowered over time.”
