Sea Level Rise Strategy

With its ongoing Sea Level Rise Strategy project, Miami-Dade County is identifying and developing financially-feasible mitigation and adaptation strategies to prepare for sea level rise and coastal storms. This includes analyzing multiple "adaptation pathways" and quantifying the economic cost of inaction.

  • Impacts of sea level rise

    Miami-Dade County is located in a unique geographical area as it is surrounded by major bodies of water such as the Atlantic Ocean, Biscayne Bay and many rivers, lakes and canals. Rising sea levels lead to other issues including:

    Coastal erosion. Sea level rise is increasing coastal erosion rates.

    Storm surge. Sea level rise can increase the height of storm surge.

    King tide flooding. Sea level rise is causing King Tides to happen more frequently, last longer and extend farther inland.

    Urban flooding. Urban flooding can be caused by short-duration, very heavy rain events. Urbanization creates large areas of impervious surfaces (such as roads, pavement, parking lots and buildings) that heavy downpours can exceed the capacity of storm drains and cause floods.

    Saltwater intrusion. Rising sea levels cause saltwater to "intrude" further landward into the freshwater Biscayne Aquifer, increasing the vulnerability of the region’s drinking water to saltwater intrusion. Additionally, rising sea levels push salt water further into the Everglades, potentially causing loss of wetland plants and habitat.

    Infrastructure impacts. Due to higher water levels in Biscayne Bay, it takes longer to drain roadways when it rains, and some low-lying roads are directly inundated by high tides. Additionally, rising sea levels increase the flood risk for buildings near the coast.

    Socioeconomic impacts. Flooding can damage property, interrupt business and increase insurance costs.

    Preparing for and adapting to climate change impacts

    As Miami-Dade County works to reduce its carbon footprint and stop fueling climate change, it must also prepare for the impacts that we know are unavoidable including sea level rise. The County is working to strengthen infrastructure, plan for more resilient communities, enhance natural protections and promote economic resilience through policies and task forces.

    The Office of Resilience works with a network of community, academic and government partners to educate the County about resilience initiatives and opportunities. For more information or to schedule a presentation, email
  • Partner initiatives

    Miami-Dade County’s longstanding commitment to address climate-related impacts is demonstrated by its leadership and partnerships with several key initiatives.
    The Sea Level Rise Strategy project will integrate these and other ongoing complimentary efforts. It will also build upon previous studies conducted by the County and incorporate city, state and federal plans for addressing sea level rise within Miami-Dade.
  • Get involved

    A second and final round of workshops will take place in July, after the first round happened in April.

    Take this online survey to express your views about the social, environmental and economic impacts of sea level rise. Your suggestions will be considered in the County's upcoming sea level strategy.

  • Project goals

    The final report from Arcadis U.S. will provide guidance on several key questions:
    • What are the impacts of sea level rise on the County?
    • What strategies will work to adapt to rising sea levels?
    • What strategies are best suited for different neighborhoods?
    • What are the benefits and trade-offs of different adaptation strategies?
    • What projects and policy changes can be implemented in the short term?
    • What decisions does our community need to make to prepare for sea level rise in the long term?
