Transcription

1 Resilient Cities nd World Congress on Cities and Adaptation to Climate Change Beyond the Storm: Risk-Based Processes and Tools to Enable Better Understanding and Management of Climate Change Risks June 3-5, 2011

2 City of Toronto, Canada Thermosyphon Foundations Coquihalla Highway Vancouver Wastewater Quesnell Bridge Edmonton Portage la Prairie Water Treatment Plant Sudbury Roads Ottawa Buildings Placentia Water Resources Toronto Culverts and Dams 1

3 Toronto: August 2005 Storm TOTAL $547 Million Toronto has 154 large culverts 2

4 Climate Change Risk Drivers and Challenges Drivers Safety: avoid harm to citizens & staff; Customer Service; Cost avoidance: damage from extreme weather credit & insurance risk rating of City & taxpayers; Legal liability of organizations and individuals; and Evidence of due diligence Challenges Inadequate data on localized future climate; Existing design codes and standards may be less applicable; Procurement & contracting policies; Infrastructure turnover and age; and Consumer behaviour and public expectations 3

5 Project Scope and Objective Scope - Climate change risk is a subset of environmental risk Enterprise Risk Environmental Risk Climate Change Risk Risks from Extreme Weather Events Climate Change Risk Assessment Process & Tool (screening level) Engineering Vulnerability Risk Assessment Adaptive Actions by City Operations Residual Risks Purpose of project - develop a process and tool for screening & prioritizing all environmental risks - first application climate change risks 4

6 Climate Change Infrastructure Engineering Vulnerability (PIEVC) Study Objectives To assess the risk of destruction, disruption or deterioration of civil infrastructure due to changing climatic conditions To understand climate change and account for it in design and retrofitting of Canadian public infrastructure To develop or revise policies, standards and tools to guide professional engineers in their day-to-day practice 5

7 Climate Change Risk Assessment (CCRA) Tool International benchmarking Process is based on ISO & aligns with ISO Risk Assessment Process Current practices from City divisions Leading environmental and climate risk assessment practices 1. Establish the Context 2. Risk Identification 3. Risk Analysis 4. Risk Treatment 6

8 Assets and Services Assessed Risk Sources Extreme Freezing Rain Extreme Rain Extreme Heat Freeze/Thaw Cycle Extreme Snowfall Extreme Cold Extreme Wind Transportation Services Infrastructure Asset Management & Programming Expressway and Structures Urban Traffic Control Systems Business Systems Plant Installation and Maintenance Road Operations High Priority Assets and Critical Services Roads, Bridges, Culverts, Inspection, Maintenance and Construction Traffic Controls Signals, RESCUE Operation; Traffic Control Systems; Business Continuity and Emergency Preparedness Plan Road Operation Equipment, Staff Health and Safety; Winter Maintenance; Road Repairs; Street Sweeping Service; Inspections and Patrolling; Investigations 7

10 Capacity Building for City Assets and Services Knowledge Professional Development Operationalize Climate Change Risk Directing Reform Facilitating Reforms Knowledge : Gathering the knowledge. This information may be technical or non-technical. Professional Development: Equipping individuals with the understanding, skills and access to information that enables them to perform more effectively. Operationalize Climate Change Risk: The review and improvement of management structures, processes and procedures. Directing Reform: Incorporating what we have learned into codes and standards. Facilitating Reform: Involves using facilitative industry reforms that use financial incentives and disincentives to achieve desired outcomes. 9

11 Benefits of the CCRA and PIEVC Tools Identifies nature and severity of risks to assets and services Optimizes more detailed engineering analysis Identifies most obvious vulnerabilities and controls and assessment of risk rating Ensures consistency and accountability due diligence through a structured, documented approach Recommends new designs, retrofitting, rehabilitation and best practices in operation and maintenance Recommends review and adjustment of codes, standards and engineering practices Demonstrates climate change adaptation leadership Provides a mechanism for communicating climate change risk 10
