Coastal Flood Adaptation Strategy

News & Updates

CFAS is Now Complete!

In 2016, the City embarked on a journey to develop a Coastal Flood Adaptation Strategy (CFAS) to help Surrey prepare for a changing climate and increase the resilience of its coastal communities. We are pleased to announce that CFAS is now complete!

On November 4, 2019 Council approved the Final Strategy Document for CFAS. Our thanks to the more than 2,000 residents, stakeholders, partners and international experts that contributed to this innovative, participatory, community-driven project.

Join us at the CFAS Wrap-up Event on Thursday, November 28, from 5 to 7pm, at the Rotary Field House, 2197 148 St. We will be celebrating the hard work and community participation that has been at the core of CFAS.

Surrey Wins Climate & Energy Action Award for CFAS

On September 25, 2019, the City of Surrey was awarded the Climate & Energy Action Award by the Community Energy Association for its leadership on climate resilience. The award acknowledges the leadership shown by the City in developing Coastal Flood Adaptation Strategy (CFAS).

About CFAS

As the climate changes, coastal areas everywhere can expect more frequent and severe flooding from storm surges and sea level rise. In Surrey, over 2,500 people will be affected in residential areas and neighbourhoods in and around Crescent Beach, Panorama/Gray Creek, Cloverdale, Inter-River Area, Colebrook, Mud Bay, Nico-Wynd/Crescent Road and Semiahmoo First Nation. The coastal floodplain area spans 20% of Surrey’s land.

To help our coastal communities become more resilient, the City is developing a Coastal Flood Adaptation Strategy (CFAS) for Surrey’s coastal floodplain area. CFAS takes a participatory, community-driven planning approach directly engaging residents, stakeholders, and other partners, including First Nations, community and environmental organizations, business associations and groups, senior governments, farmers, the agricultural community, and neighbouring jurisdictions to identify short, medium and long-term options to adapt.

Public Consultation & Workshops

CFAS has been engaging with residents, stakeholders and partners since 2016. The results of this participatory planning process are summarized in the project Engagement Report for Phases 1-3. Highlights of the engagement efforts so far include:

  • 100,000+ Social Media Impressions
  • 1,750+ online surveys completed
  • 500+ worksheets completed
  • 200+ Surrey Youth Engaged
  • 200+ Community Conversations
  • 8 Pop-up Project Outreach Stations throughout Surrey
  • 7 Technical workshops
  • 5 Crescent Beach Workshops
  • 3 Sector Based Focus Groups
  • 3 Project Advisory Group Workshops
  • 2 Project Open Houses
  • 2 Coastal Site Tours

The April 2018 Open House summarized the findings of Phase 2 and 3, and a subsequent update is available in the 2018 CFAS Year End Update Presentation. A final project Open House will be scheduled in 2019.

To hear stories from our residents and stakeholders, see the CFAS YouTube Playlist.


Learn about the 10 options developed for adapting to coastal flooding in Surrey. The options cover Crescent Beach, Semiahmoo Bay and Mud Bay/Cloverdale.


The CFAS project is broken into five phases illustrated below along with a general project timeline. The inclusive, participatory approach is the foundation in each of the five project phases and ensures we develop a set of preferred strategies that are robust, transparent and defensible.

    Collapse/Expand All
  • Phase 1: What matters most and who is affected? expand
  • (Summer 2016 – Spring 2017) 

    This phase developed hazard communication materials to communicate current and future flood risks across the study area to all stakeholder group.  A series of workshops, an online survey and an open house helped identify preliminary community values to support the evaluation of flood protection alternatives.

    CFAS Phase 1


  • Phase 2 and 3: What can we do and what is acceptable expand
  • (Fall 2017 – Winter 2018) 

    In this phase, adaptation options are envisioned, refined and evaluated. This is a highly technical phase to assess the appropriateness of a wide range of adaptation options across engineering, economic, social, cultural and ecological indicators. Adaptation strategies are being refined with stakeholder and partner input. A project Advisory Group of more than 30 organizations was established to assist in refining strategies and refining options.

    CFAS Phase 2 and 3

  • Phase 4: How will we do it? expand
  • (Spring 2018 – Summer 2019) 

    In this phase, a small number of robust, broadly supported adaptation strategies with phasing are refined into preferred strategies based on cost, funding and partnerships.

    Also as part of this phase, working closely with potential partners, City of Surrey submitted a $76.6M funding request to the federal government, under the Disaster Mitigation and Adaptation Fund to implement priority coastal flood adaptation works.

    On May 24, 2019, the Government of Canada confirmed a $76.6M investment to help implement a comprehensive flood adaptation strategy that will increase flood resilience and protect over 125,000 residents, homes and businesses who are at high risk of coastal flooding. This funding will help build, rehabilitate and expand 13 infrastructure assets in Surrey and surrounding communities.

    To close out phase 4, a Draft Strategy Document for the Surrey Coastal Flood Adaptation Strategy was endorsed by Council in July 2019.

    CFAS Phase 4 process


  • Phase 5: Reporting back expand
  • Fall 2019 – Winter 2019

    In this phase, the Draft Strategy Document for the Surrey Coastal Flood Adaptation Strategy was shared with the public for feedback.

    The Final Strategy Document for the Surrey Coastal Flood Adaptation Strategy was endorsed by Council in November 2019.

    The final project materials will be circulated and a wrap-up event will be hosted on November 28, 5–7pm at the Rotary Field House.


    CFAS Phase 5



In Surrey lowlands, multiple components of a flood control system work together to manage coastal flooding. The animation below illustrates how the land is at a higher risk of being flooded when high ocean levels coincide with heavy rainfall, together putting a strain on the flood control system.
