1 Metro Vancouver Sustainability Breakfast April 14, 2016 Matt Osler, P.Eng. Sr. Project Engineer City of Surrey

2 About Surrey Population: 500,000 + Growing at 1,000 + people per month 1/3 of land in Agricultural Land Reserve Highest population density in City Centre

3 Community Climate Action Strategy Mitigation Mitigating the release of GHG emissions to minimize future climate change Adaptation Adapting or preparing for the unavoidable impacts of climate change +

4 Surrey s Climate Adaptation Strategy Working with ICLEI Canada: Local Governments for Sustainability Building Adaptive, Resilient Communities (BARC) 2011 Council Report Advisory Team Top 10 Actions Implementation work plan Risk Management Framework Likely social, economic, and environmental impacts of climate change 2011 Background Research Risk Assessment Staff Working Groups Strategy Development Stakeholder Engagement

5 Surrey s Climate Adaptation Strategy Six sectors: Implementation: Flood Management and Drainage Infrastructure Lead and Supporting Departments Role or Jurisdiction Health and Safety Ecosystems Sectoral Goals Actions Tools or Supporting Policies Urban Trees Agriculture and Food Security High Priority Actions High Level Cost Categories

6 Climate Projections & Key Risks Climate Projections: More variable weather patterns Warmer average temps and extreme heat days Changes to precipitation; likely wetter winters, dryer summers Sea level rise Some Key Risks: Flooding and drainage issues Tree mortality and ecosystem change Viability of agriculture, food insecurity Water shortages Energy insecurity Damage to infrastructure Urban-w ild land interface fire risk Urban heat island and heat stress Disease vectors and health issues Sample Impact Statement: Increase in frequency and duration of flooding within low lying floodplains due to reduced system drainage resulting from sea level rise and more intensive precipitation events

7 Sustainability Actions Identified lead departments and tools, as well as 11 actions for immediate implementation:

8 Engineering Decisions & Context

9 Observed Impacts and Short Term Actions Street Trees Increased watering requirements for trees. Flooding More frequent surface ponding and flood incidents in Crescent Beach. Year Total # of Decommissioned Trees Mortality Rate % % %

10 Engineering Planning Process The 10 Year Servicing Plan included a new component in the Drainage Utility for Climate Change investigations & strategy development.

11 Key directions: Flooding & Drainage Collaborate with stakeholders to develop a Regional Flood Management Strategy Fraser Basin Council Facilitating Lower Mainland Flood Strategy Update planning and development standards for floodplains Incorporate Climate Change Impacts in Capital Projects Reduce risk and increase resilience and flexibility

12 Sea Level Change relative to 2000 [m] Background Changes in Provincial Guidelines Provincial reports regarding the estimated costs to address the impacts of sea level rise and other coastal hazards in Surrey ($1.6 billion); and Change in Provincial dyke design standards (2011). 5 4 Recommended Curve for Sea Level Rise Policy in BC

13 Serpentine, Nicomekl & Campbell Rivers Climate Change Floodplain Review - Phases 1 & 2 Dyke Integrity / Likelihood of Breach under extreme water levels Low / Likely Moderate / Unlikely High / Very Unlikely Infrastructure Impact from 200 yr. return Water Level Sea Dams: Bridges: Dry Dry Compromised Compromised Wet Wet

16 City Impact Graphics Coastal Flood Protection Strategy Launching a 3 year public and stakeholder engagement to determine how we want to address sea level rise.

17 Development of a Coastal Strategy 2016 Council Endorsed Development of Visioning and Consultation Process Develop options for flood protection through stakeholder engagement 2017 Evaluate draft options and refine options with stakeholders 2018 Present preferred Coastal Strategy for Council s consideration. Secure funding partners for Coastal Strategy.

18 Maintaining Momentum on Implementation Not everything under the banner of adaptation Risk Management and Design Guidelines Alignment with higher and lower level plans Linking with Regional efforts Engage Stakeholders to make integrated infrastructure decisions
