RESILIENT Cedar key
Vulnerability Assessment and Adaptation Plan
Reimagining Cedar Key’s future through vulnerability assessment, community engagement, and adaptation planning for long-term coastal resiliency, including a new civic center, adaptive housing, and community-centered urban design.
Cedar Key is a historic coastal community located on the Nature Coast in Florida’s Gulf of Mexico. Despite its small population, the city remains a relevant regional location due to its historic, cultural, economic, and ecological value. Shaped by coastal economic activities, transportation, and the old Florida Railroad, Cedar Key today supports thriving aquaculture, coastal tourism, and environmental research.
However, its low-lying coastal setting and close relationship with the surrounding environment also create increasing challenges from flooding and future climate impacts, emphasizing the need to better understand vulnerabilities and plan for long-term adaptation.
Florida’s Gulf Coast faces increasing climate risks from sea level rise, stronger storms, and coastal flooding. Due to its low-lying topography and direct exposure to the Gulf of Mexico, Cedar Key is particularly vulnerable to these impacts. Rising water levels, shoreline erosion, and aging infrastructure continue to create challenges for transportation networks, utilities, homes, businesses, and the aquaculture industry that supports the local economy.
Recognizing these growing risks, the City of Cedar Key partnered with the University of Florida to develop a comprehensive Vulnerability Assessment and Adaptation Plan. The study evaluates future climate exposure, identifies vulnerable community assets and infrastructure, and provides data-driven strategies to guide long-term adaptation, strengthen resilience, and support sustainable decision-making.
What is the Study About?
Resilient Cedar Key is a multiyear collaboration with the City of Cedar Key that supports the community in adapting to climate-related challenges while preserving its historic character and economic activity. This initiative began with a comprehensive Flood Vulnerability Assessment that identifies climate risks, evaluates impacts on critical assets, and includes an actionable Adaptation Plan outlining practical strategies to enhance resilience across Cedar Key. Using innovative digital tools for community participation and translating public policy into a spatial framework for adaptation, the study envisions flood resilience as a resource to preserve and enhance Cedar Key’s spatial qualities.
Vulnerability Assessment
Adaptation Plan
Vulnerability Assessment
Evaluates exposure and sensitivity of critical assets to rainfall, tidal, and storm surge flooding.
Study Area
Structured around its complex geography and hydrologic connections, the study area is organized into six zones, each with distinct districts and community characteristics.
Critical Asset Categories
Transportation
Transportation vulnerability is concentrated along access the road from the mainland and key corridors throughout Cedar Key. Flooding along these vital connections threatens emergency response, daily mobility, and access to essential services.

Housing
Housing vulnerability occurs generally in low-lying residential areas and along the shorelines. Most of this assets are vulnerable to a Category 1 storm event.

Critical Infrastucture
A category 1 storm will heavily impact most of the community and emergency facilities. Assets at risk include the school’s western access, main pedestrian tourist and restaurant areas, post office, library, city hall, fire station, and food pantry.

Community Emergency
Community and emergency facilities are concentrated in areas with increasing flood exposure, placing essential public services at greater risk during future coastal hazards. Reducing flood impacts is to ensuring uninterrupted emergency response, public services, and community support.

Natural & Cultural Resources
Natural and cultural resources will experience a stark increase in flood exposure over time, with any extreme water level event affecting all the parks or recreational areas.

Local Economy
As tidal flooding intensifies, most of Cedar Key’s economic assets, including the shops, restaurants, and tourist spaces in the historic core, will be at high risk. The tourist area along Dock Street is highly vulnerable to moderate storm-surge events, such as a Category 1 hurricane.

Compound Vulnerability
The Compound Vulnerability Assessment synthesizes results from all critical asset categories to identify where multiple risks overlap across Cedar Key. The assessment highlights four priority areas that will guide future adaptation strategies and resilience investments.
Focus Area 1 – Downtown Cedar Key
Highest overall vulnerability across community assets, critical infrastructure, transportation, community facilities, and businesses.
Focus Area 2 – Mid Cedar Key
Combined vulnerabilities across housing, critical infrastructure, natural resources, and, most importantly, transportation connectivity.
Focus Area 3 – West Cedar Key
Primary vulnerabilities in residential areas, natural resources, and transportation access.
Focus Area 4 – North Cedar Key
Vulnerabilities centered on transportation connectivity to the mainland, housing, and local economy assets.
Adaptation Plan
Defines and prioritizes actions to reduce vulnerability, protect critical assets, and guide long-term adaptation strategies.
Adaptation Focus by Zone
Building on exposure and sensitivity analyses, the adaptation focus by zone identifies zone-specific vulnerability dynamics, guides the identification and goals of individual adaptation actions, and defines a framework for an integrated resilience system.

Spatial Framework for Adaptation Actions and Areas
The Spatial Framework provides a comprehensive vision for implementing adaptation strategies across Cedar Key. It identifies priority actions through three main strategies—infrastructure and redevelopment, waterflow neighborhoods, and green flood buffers—organized across four adaptation project areas to guide long-term resilience planning.
PROJECT 1: transportation Infrastructure
Elevating 3rd St. to protect downtown and ensure connectivity. Future sea level rise is expected to disrupt access throughout Cedar Key, particularly between State Road 24, the downtown waterfront, and surrounding neighborhoods. By 2040, portions of 1st, 2nd, and 3rd Streets are projected to experience flooding during high tides and frequent storm events. This project proposes elevating 3rd Street between A and D Streets to maintain connectivity, reduce downtown flooding, and improve access to homes and businesses. The design also incorporates a stepped transition to a publicly accessible marsh that enhances storm surge protection while supporting mangrove restoration.
PROJECT 2: mOVING CITY HALL
Relocating Civic Infrastructure to High Ground. The vulnerability assessment suggests that many civic buildings are at risk in Cedar Key. This was demonstrated recently during the historic flooding of Hurricane Idalia. This proposal explores moving civic buildings, including City Hall and other essential services, permanently to the Community Center. It also investigates alternative designs for the site, including new buildings, potential mixed-use development with housing, and landscape improvements.
PROJECT 3: MID CEDAR KEY
Restoring Hydrologic Flow. Cedar Key is an archipelago. The island needs to allow water to flow through, not around it. This project focuses on restoring water flow through the island at three vulnerable locations. The image highlights a proposed new bridge from Indiana Avenue to Cemetery access that will restore hydrologic connectivity during extreme high tide events. This study establishes a replicable approach for other vulnerable areas across the island.
PROJECT 4: WEST CEDAR KEY
Granular Adaptation to Change. Much of Cedar Key is low-lying and low-density, making small-scale adaptation and nature-based solutions essential for reducing flood risks. This project promotes land conservation, home elevation, and expanded participation in the Community Rating System (CRS) program, while encouraging strategic land acquisition and post-disaster planning to limit future development in vulnerable areas.
