BACKGROUND

4

• Challenges identified in July 2021 GVS&DD Board Report• Constructability; solids-treatment capacity; schedule constraints; and cost increases• Compliance with regulatory deadline ~2034 (4 years late)• Estimated costs =$6.7B in 2021 dollars; $10.4B with escalation and risk reserve

• Recommending Revised Design Concept to address challenges• Committees: LWC – November 4; FIC – November 10• GVS&DD Board – November 26

Page 6: Rendering -freshwater wetlands and tidal channels Iona

REVISED DESIGN CONCEPT

6

• Concurrent construction of digesters and compact-footprint secondary treatment process (Membrane Bioreactor or Aerobic Granular Sludge)

• Offer capital cost savings in the order of 10%• Flexibility to validate performance and costs in preliminary design• Address commercial considerations as part of due-diligence

• What’s not changing• Tertiary level wastewater treatment • Odour control • Resource recovery opportunities• Ecological restoration projects• Iona Beach Regional Park integration

Iona Beach Regional Park Impacts and Benefits

16 of 53

Page 17: Rendering -freshwater wetlands and tidal channels Iona

• Concurrent digester construction • Eliminates trucking sludge off-site • Protects desired Musqueam views• Net gain in park land, including

~ 18 ha transfer from GVS&DD

TREATMENT PLANT LAND REQUIREMENTS

17

Revised Design Concept layout requires ~3 ha of MVRD park land

Draft VisionMetro Vancouver regional parks are protected, resilient, and adaptable, connecting people to

nature, with benefits for all

43 of 53

Page 44: Rendering -freshwater wetlands and tidal channels Iona

DRAFT GUIDING PRINCIPLES

16

Sustainable Nature has inherent value and its protection for future generations is the foundation of what we do

Interconnected Our work nurtures the essential connection between people and natureReconciliation-focused Relationships with Indigenous Peoples are strengthened as we journey

together along the reconciliation pathwayInclusive Equity is integral to what we do, as we create an inclusive

environment for allCollaborative By working with others, we collectively steward the land to improve

the region’s livability and ecological healthKnowledge-based Decision-making is informed by data and science, and seeks to

incorporate Indigenous ways of knowingAdaptive Through learning, innovation, and evaluation, we sustain a culture of

adaptive management

44 of 53

Page 45: Rendering -freshwater wetlands and tidal channels Iona

DRAFT GOALS

17

1. The region’s important natural areas are protected in perpetuity2. First Nations have an active role in the planning and stewardship of

regional parks3. Everyone has the opportunity to benefit from exceptional experiences

in nature4. Regional parks adapt to change and contribute to regional resiliency5. Regional parks are sustainably managed and well-maintained to

ensure the safety of visitors and integrity of ecosystems
