Surrey Climate Change Planning
Priority Actions:
“Conduct detailed analysis on Surrey-specific climate impacts, including timelines and extent of sea level rise and its related effects on flood construction levels and floodplain designations”

Surrey CFAS Process• Many stakeholders
– Farmers and agricultural community– Residents, businesses, community
groups– Environmental and recreational
groups– Infrastructure operators and owners– Semiahmoo First Nation
![Page 7: January 23, 2019 FBC Flood & Environment Workshop · •What gets measured gets managed –Partnered with Ducks Unlimited and Friends of Semiahmoo Bay to secure grant funding and](https://reader035.vdocument.in/reader035/viewer/2022070800/5f0212707e708231d4026efd/html5/thumbnails/7.jpg)
Approach & Process• Participatory, values‐based, iterative
![Page 8: January 23, 2019 FBC Flood & Environment Workshop · •What gets measured gets managed –Partnered with Ducks Unlimited and Friends of Semiahmoo Bay to secure grant funding and](https://reader035.vdocument.in/reader035/viewer/2022070800/5f0212707e708231d4026efd/html5/thumbnails/8.jpg)
Process Flexible to fill data gaps• More engagement = more questions!• Data on land assets exceeded marine asset data• What gets measured gets managed
– Partnered with Ducks Unlimited and Friends of Semiahmoo Bay to secure grant funding and collect information
– Funding Partner (FCM MCIP) wanted more than data, required recommendations for action and risk assessment
– Reserved >10% of budget for communication

Adaptation Through CollaborationCollaboration• Across region with Fraser Basin Council and MV• Across City departments• Across external groups through a project
advisory group• Post secondary institutions and global experts• Community Charrettes and community groupsBroad engagement• Libraries, public spaces, school district, contests
Sector based engagement • Agriculture, environment, infrastructure focus
groups• Education – Green Shores & PIEVC workshops• Local tours with diverse stakeholders to discuss the
issues and build understanding• Online through web based information, surveys,
social media, videos

Implementation Challenges
• Trade‐offs in implementing solutions• Regulations that preserve the status quo• Lack of integration in coastal regulation across jurisdictions
• Need a robust process to resolve based on values

• Existing freshwater habitat poses constraint• Existing land rights poses constraint (Agricultural
Land Reserve, Highway dedications, Railway lands etc.)
