Coastal Flood Adaptation Strategy

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

Meetings and workshops have been hosted in 2016, 2017, and 2018. Review the most recent Open House materials from April 2018.

Learn about the public consultation that has taken place and hear stories from our residents. Take a look at our 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 the five project phases and ensures we develop a set of preferred strategies that are robust, transparent and defensible.

  • Phase 1: What matters most and who is affected? expand
  • Phase 1: What matters most and who is affected?

    (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.

  • Phase 2 and 3: What can we do and what is acceptable expand
  • Phase 2 and 3: What can we do and what is acceptable

    (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
  • Phase 4: How will we do it?

    (Spring 2018 – Winter 2018/19) 

    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.

  • Phase 5: Reporting back expand
  • Phase 5: Reporting back


    In this phase, the final reporting and visual materials for broad dissemination are developed and delivered through broad communications.

    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.

To learn more about coastal flooding and the roles different components of the flood control system play in protecting our lands from flooding, see the CFAS Primer Part 1: Coastal Flooding in Surrey, or watch a short video on Coastal Flood Management in Surrey.
