Agenda 2
How LGPAC & CRF input has influenced : • Objectives Hierarchy • 9 Design Concepts • 3 Build Scenarios 3
Example – Impact of Community Input Date Consultation Impact of your input Activity • Shaped development of 9 concepts Jun 2012 LGPAC Mtg #1 • Informed site design Sep 2012 Community • Input considered by municipalities Workshop #1 • Revised objectives framework Nov 2012 Community • Directly shaped specific objectives Workshop #2 • Direction on 9 concepts Feb 2013 LGPAC Mtg #4 • Informed development of 3 scenarios • Design direction for 3 scenarios (eg. Apr 2013 Community Workshop #3 estuary discharge) • Community interests/questions/ concern Apr 2013 Public Meeting provided direction in assessment of 3 build scenarios 4
Objectives Hierarchy Control Odour Consider truck traffic Minimize impacts noise Examples of things we heard from LGPAC and CRF that influenced the evaluation framework Future proofing Design for including climate change population growth and disasters 5
Objectives Hierarchy Establish Create a place connections to the people want to live surroundings Examples of things we heard from LGPAC and CRF that influenced the evaluation framework Recover water, Water energy, nutrient conservation resources Protect and enhance the environment 6
9 Design Concepts 2 3 4 6 7 8 9 1 5 Control Focus on Multi-use to leverage Odour costs / value infrastructure for amenities Examples of things we heard from LGPAC and CRF that influenced the development of the 9 Design Concepts Connect the Public community to education Reduce the waterfront A tourist nuisances attraction for (noise, dust) the North Shore 7
3 Build Scenarios Ecology (Concepts 1, 7, 8) • Regenerative design 1 3 2 • Passive onsite habitat • Urban garden Integrated Resource • Tiered greenery Recovery (Concept 4) • On -site IRR, but not Examples of things LGPAC trucking off site members told us they thought were • Feed the energy the most appealing in the 9 design requirements of the industrial community concepts, that then influenced the 3 Build Scenarios Flexibility (Concept 3) Additional uses / Cost-effectiveness (Concepts 6, 9) • Adaptability • Office space • Accommodate • Multi -purpose community space future population • Artist studios and incubator industries growth / technology • Complementary businesses • Smaller footprint • Sustainable from a cost perspective 8
Overview of Structured Decision Making (SDM) Process used by Metro Vancouver for evaluating alternatives Graham Long Compass Resource Management Structured-Decision Making Workshop May 31, 2013
Objectives for this workshop • To introduce and discuss the methodology being used by Metro Vancouver to create and evaluate potential alternatives • To clarify how LGPAC / CRF input has been used and will be used in future • To engage participants in weighting exercises that help explore and communicate preferences to Metro Vancouver • To provide an update on the current status of the project and to seek further input on key trade-offs for the three Build Scenarios 10
Overview of Structured Decision Making (SDM) “… a formalization of common sense for decision problems which are too complex for informal use of common sense." Ralph Keeney 11
Overview of Structured Decision Making (SDM) • Based on decision analysis principles that date back to the 1940s • One of many variants on a theme • Multi-attribute trade-off analysis • Multiple account evaluation • Kepner Tregoe is another variant 12
Overview of Structured Decision Making (SDM) All these methods rely in some way on: • Defining a context – what‟s the decision all about? – w hat are the “must haves” or “must not haves”? • Defining objectives (the things that matter) • Developing alternatives • Evaluating the impact of alternatives on objectives – Some techniques use weighting to assist in this 13
Overview of Structured Decision Making (SDM) Example: buying a truck Alternatives Objectives and measurement scales 14
Overview of Structured Decision Making (SDM) What’s different about SDM? • Less focus on using pre- defined weights to automatically select a „winner‟ • More focus on using structure to inform discussion • Uses multiple weighting techniques to help understand and communicate what people prefer and why • Ultimately, uses structure as a prop to debate 15

Lions Gate SWWTP Must haves include: • Ability to treat wastewater from the North Shore to secondary standard as defined by the Wastewater Systems Effluent Regulations under the federal Fisheries Act, and as committed to in Metro Vancouver’s Integrated Liquid Waste and Resource Management Plan, approved by the Minister in 2011. • Must be in service by Dec. 31, 2020 • Meet the four goals of: 1. Secondary treatment 2. Sustainability 3. Integrated Resource Recovery 4. Community Integration 17
