Purpose of the Plan:

Develop a Sewage and Rainwater

Management Plan for Vancouver (SRMP) to:

• address aquatic pollution from combined

sewer overflows (CSOs) and urban

rainwater runoff

• secure adequate sewage and drainage

capacity for a growing population and

climate change

• Sewage and rainwater management services are

jointly provided by the City and Metro Vancouver:

• The City is responsible for providing sewer and drainage

services to individual properties, and managing local

collection and conveyance

• Metro Vancouver is responsible for major conveyance and

sewage treatment infrastructure.

• A high level of collaboration is required to:

1. identify infrastructure, policy and regulation options that are

optimized across the joint municipal-regional system; and

2. maximize alignment between LWMP commitments and

Vancouver sewage and rainwater management plan.

38

Pathway Definition:

“Pathways” are defined as bundled combinations of

investments, policies, programs, partnerships,

collaboration and decision frameworks that work in

concert to achieve objectives and milestone

performance targets through time.

Part II – Pathway Development

39

Consultants pathway development

approach will include:

• Use of value-based thinking and objective setting;

• Shared learning amongst stakeholders;

• A structured process, using the necessary decision

making tools (eg. consequence tables, visual

representations etc.);

• Assess the performance of exploratory pathways

against performance criteria aligned with objectives

Part II – Pathway Development

40

Consultants pathway development

approach will include:

• Development of a financial model to inform

performance;

• Co-develop a preferred pathway through a shared

understanding of impacts and potential trade-offs;

and

• Identify uncertainties and develop processes,

methods or clear triggers, to be captured as actions

within the Plan to manage these uncertainties.

Part II – Pathway Development

41

Key Plan Components

1. Vision

2. Detailed implementation and financial strategy

3. Actions with timeline and milestones

4. Recommended changes to, or new, policy and regulations

Known Knowledge and Data Gaps

• Modelling

– No detailed City-wide model – under development

– Detailed modelling progressed in areas that are high priority for area planning (e.g. Cambie, Broadway)

• Monitoring

– Limited to 13 rain gauges, 37 flow locations, and 10 CSO flow locations

– Water quality data for CSO and stormwater outfalls

• Sewer Asset Management

– Draft Risk Based Decision Making Framework

– Level of Service Target not Established
