2 Overview 1. Introduction to Floodplain Maps 2. Federal Floodplain Mapping Guidelines Series 3. Stakeholder Engagement 4. Hazard and Risk Assessment 5. Next Steps 2

3 Introduction Natural Resources Canada is providing technical support and expertise to the National Disaster Mitigation Program administered by Public Safety Canada. National Disaster Mitigation Program $200M Risk Assessments Flood Mapping Mitigation Planning Investments 3

4 Floodplain Maps Promote information on flood hazards Enable community preparedness and disaster mitigation planning Empower citizens and property owners Inform emergency management practices General public awareness Land use planning Necessary condition to enable insurance Investments in infrastructure Used in emergency management cycle 4

5 Floodplain Maps Inundation Maps Show floodwater extents Used for emergency management and other rapid-production uses 5

6 Floodplain Maps Hazard Maps Engineering Maps showing extents of different floods Can include depths and velocities 6

7 Floodplain Maps Risk Maps Show risks of flood hazard to socioeconomic values Used to identify consequences of flooding 7

8 Floodplain Maps Awareness Maps Communicate flood information to public Can include historical information and advice 8

9 Guidelines Series The Federal Floodplain Mapping Guidelines Series documents are being published to inform consistent practices for floodplain mapping in Canada. Collaborative Interoperable Evergreen Local Accessible Adaptable Voluntary 9

10 Guidelines Series Objectives Recognize provincial/territorial roles and responsibilities for flood mitigation Provide basis for further specification by provinces & territories Inclusive and take regional considerations into account Encourage sharing and dissemination of flood hazard information Serve all floodplain mapping practitioners and stakeholders The Guidelines are not standards they are recommended common practices. 10

11 Guidelines Series 11

13 Stakeholder Engagement Ongoing engagement since 2015 Workshops, consultation meetings, teleconferences/webinars, conferences, and contracts Technical Working Group 160 members across Canada representing all levels of government, academia, industry, consulting, and other stakeholders Ongoing consultation Federal Flood Mapping Committee Representatives from NRCAN, PS, ECCC, DND, DRDC, NRC, INAC, and INFCAN Studies and reports Research and private consultants 13

14 Hazard and Risk Assessment Flood Hazard: a potentially damaging flooding event that may cause the loss of life or injury, property damage, social and economic disruption, or environmental degradation. Flood Risk: the combination of the likelihood and the consequence of a Flood Hazard. 14

15 Hazard and Risk Assessment Risk Assessment Documents: 1. Flood Risk Assessment Guidelines Series document In progress 2. Guidelines and Database of Flood Vulnerability Functions Annex to Flood Risk Assessment document In progress 3. Risk Based Land Use Guide Published by NRCan (2015) Addresses flooding and other hazards 15

16 Hazard and Risk Assessment 16

17 Hazard and Risk Assessment National Risk Profile for Canada The objective of this initiative is to design a sustainable approach for national risk assessment: top-down risk assessment methods (national scenario-based planning; capability assessment; and critical infrastructure interdependence); bottom-up municipal level assessments (submitted under the National Disaster Mitigation Program and local hazard mapping and modelling initiatives). 17

18 Hazard and Risk Assessment The National Risk Profile aims to design and pilot a sustainable approach for National Risk Assessment: Part 1: National Risk Profile Document Part 2: Structure and Governance Model 18

19 NRP System NRP Document Flood Maps Hazard and Risk Assessment Chapter 1: Capability-based planning Chapter 2: Communitybased planning Chapter 3: Hazard/Risk Modelling Regional Profiles All-hazards Risk Assessment National Risk/Resilience Aggregation Process NDMP Risk/Resilience Common Input Templates NDMP Risk/Resilience Toolkit National Flood Mapping Guide lines National Disaster Mitigation Program 19

20 Next Steps Consultation on the Federal Floodplain Mapping Guidelines is ongoing: CRHNet 2017 March 2018 Flood Risk Assessment Workshop Contracts with consultants Consultations with Provinces / Territories Engaging Indigenous communities 20

21 Conclusion The Federal Floodplain Mapping Guidelines Series is laying the groundwork for a more resilient future by promoting common approaches to floodplain mapping across Canada. 21
