Harris County, Texas established a voluntary home buyout program through the regional government agency, the Harris County Flood Control District (HCFCD), that can serve as an example for other local jurisdictions considering retreat from coastal and riverine flood-prone areas. The buyout program is focused on risk reduction and flood mitigation best practices, where once bought out, properties are returned to open space uses to restore their natural beneficial flood retention functions. HCFCD has developed an effective communication and outreach strategy to educate the public and encourage program participation. Historically, properties have been acquired with grants from the Federal Emergency Management Agency’s Hazard Mitigation Assistance program, Department of Housing and Urban Development’s Community Development Block Grant program, and local funding from a dedicated ad valorem property tax (i.e., a tax based on a property’s assessed value). Other state, regional, and local jurisdictions considering managed retreat could implement a similar comprehensive buyout model that operates in both a pre- and post-disaster context to reduce flood risks and engages the community throughout the entire process. This case study is one of 17 case studies featured in a report written by the Georgetown Climate Center, Managing the Retreat from Rising Seas: Lessons and Tools from 17 Case Studies.

The New York City Department of Environmental Protection (NYC DEP) offers flood mitigation buyouts within the NYC watershed, in cooperation with the state, through a Flood Buyout Program that can serve as a model for other coastal and riverine jurisdictions considering retreat. These buyouts are part of a comprehensive flood hazard mitigation program that relies on scientific studies termed Local Flood Analyses (LFA). LFA enable NYC DEP to identify solutions to reduce flooding, which may involve buyouts, and then to fund and implement recommended projects. NYC DEP’s buyouts are primarily funded by local sewer and water bills and may be supplemented by grants from the Federal Emergency Management Agency. Notably, NYC DEP administers a Land Acquisition Program — in addition to its Flood Buyout Program — with a focus on conserving land within the NYC watershed to protect water quality. This dual approach to both buyouts to mitigate flood risk and open space acquisitions to enhance water quality is a unique model that other state and local governments can replicate to achieve co-benefits through land acquisitions. Collectively, NYC’s multiple programs and projects can provide an example for other land-use planners and decisionmakers on how managed retreat through buyouts can be supported through a science-based, comprehensive approach that aims to maximize floodplain hazard mitigation and community resilience. This case study is one of 17 case studies featured in a report written by the Georgetown Climate Center, Managing the Retreat from Rising Seas: Lessons and Tools from 17 Case Studies.

The Los Cerritos Wetlands Oil Consolidation and Restoration Project (project) provides an example of how public-private land swap arrangements can be aligned with environmental restoration and protection plans, and used to advance long-term visions for managed retreat. The Los Cerritos Wetlands Complex, located in Long Beach, California, has faced decades of degradation from human activities and development. Much of this remaining wetlands area is privately owned and used to conduct oil operations. The proposed project would transfer 154 acres of privately owned wetlands to public ownership as part of a land swap arrangement. Specifically, as a part of the land swap, the 154 acres currently used for oil production will be exchanged for five acres of wetlands currently owned by the Los Cerritos Wetlands Authority. The land swap will facilitate restoration of a major portion of the wetlands via a mitigation bank, increase public access, and reduce the oil production footprint and consolidate operations. The land swap plan also involves a number of environmental and social tradeoffs, however. These considerations can provide lessons and recommendations for other local governments studying land swaps as a legal tool to facilitate retreat in coastal areas. This case study is one of 17 case studies featured in a report written by the Georgetown Climate Center, Managing the Retreat from Rising Seas: Lessons and Tools from 17 Case Studies.

In February 2019, the State of Hawaii Office of Planning, Coastal Zone Management Program (CZMP), published a report: Assessing the Feasibility and Implications of Managed Retreat Strategies for Vulnerable Coastal Areas in Hawaii (report). CZMP drafted the report in response to a request for the state to evaluate the potential for a managed retreat program in Hawaii. In developing the report, CZMP designed and implemented a three-phased approach that consisted of conducting background research; evaluating how retreat could apply in four different area typologies; and convening an interdisciplinary symposium to engage experts and stakeholders. As a result, CZMP concluded that it is not currently possible for Hawaii to develop a step-by-step plan to implement managed retreat for areas in the state threatened by sea-level rise and other coastal hazards; however, the report contains recommendations for potential next steps , including assembling an interdisciplinary committee to work towards achieving a statewide consensus about a managed retreat vision and efforts to formulate a retreat strategy. Both Hawaii’s three-phased approach and the final report provide helpful examples of how one state designed and implemented a comprehensive process led by its CZMP to evaluate the potential for retreat.

The harborside city of Punta Gorda, Florida has responded to the threat of coastal storms and climate change impacts with two different plans - a Climate Adaptation Plan and a local comprehensive plan - to promote, manage, and protect the city’s natural resources and plan for development in a way that minimizes risks to people and property and conserves ecosystems. The Adaptation Plan is unique because it was developed through a “citizen-driven process” designed to identify effective local responses to climate change and includes a variety of adaptation options that enjoy broad community support, including managed retreat or “planned relocation.” The city incorporated the Climate Adaptation Plan into its comprehensive plan to ensure that climate change is considered in land-use decisionmaking efforts. In 2019, the city released an update to its Adaptation Plan that identifies the city’s progress to date and future adaptation actions the city could consider implementing. Punta Gorda provides a useful example of how effective community engagement can enhance adaptation planning and build community support for managed retreat strategies and how adaptation plans can be used to inform future land-use decisions to ensure safer, more resilient development.

Quinault Indian Nation (QIN), a federally recognized tribe located in Washington state, is currently implementing a phased relocation plan as part of a managed retreat strategy in response to the impacts of sea-level rise, flooding, and concerns about the increased likelihood of tsunamis and storm surges attributed to climate change. In 2017, QIN adopted the Taholah Village Relocation Master Plan that outlines a vision and development plan for relocating a portion of QIN living in the Lower Village of Taholah to a higher ground location in the Upper Village Relocation Area. The Master Plan contains eleven chapters covering the history and the need to relocate, goals and principles of the plan, and different aspects of the Upper Village blueprint including appropriate community facilities, housing, infrastructure, culture, sustainability, and resilience. It also sets forth implementation steps for the project through phasing, necessary regulatory changes, and funding. QIN developed the Master Plan with significant community input. The community engagement processes and sustainable planning strategies can provide transferable lessons for other state and local jurisdictions considering similar questions of strategic planning for coastal retreat and relocation, even on a smaller scale. This case study is one of 17 case studies featured in a report written by the Georgetown Climate Center, Managing the Retreat from Rising Seas: Lessons and Tools from 17 Case Studies.

This report, produced by the Georgetown Climate Center, features 17 case studies about how states, local governments, and communities across the country are approaching questions about managed retreat. Together, the case studies highlight how different types of legal and policy tools are being considered and implemented across a range of jurisdictions — from urban, suburban, and rural to riverine and coastal — to help support new and ongoing discussions on the subject. These case studies are intended to provide transferable lessons and potential management practices for coastal state and local policymakers evaluating managed retreat as one part of a strategy to adapt to climate change on the coast. The case studies in this report were informed by policymakers, practitioners, and community members leading, engaging in, or participating in the work presented in this report. This report was written to support Georgetown Climate Center’s Managed Retreat Toolkit, which also includes additional case study examples and a deeper exploration of specific legal and policy tools for use by state and local decisionmakers, climate adaptation practitioners, and planners.

Louisiana Strategic Adaptations for Future Environments (LA SAFE) is a community-based planning and capital investment process that will help the state fund and implement several projects, including for managed retreat, to make its coasts more resilient. In 2016, Louisiana’s Office for Community Development–Disaster Recovery Unit received a nearly $40 million grant from the U.S. Department of Housing and Urban Development through the National Disaster Resilience Competition and additional state and nongovernmental funds to implement LA SAFE. The grant will support the design and implementation of resilience projects to address impacts in six coastal parishes that were affected by Hurricane Isaac in 2012. The state partnered with the nonprofit Foundation for Louisiana to administer LA SAFE and facilitate an extensive, year-long community engagement process that will result in implementation of ten funded projects across the six parishes. By contemplating a regional, rather than a parish-specific, approach to addressing coastal risk, LA SAFE provides a model that other states and local governments may consider when making long-term adaptation and resilience investments, including for managed retreat. This case study is one of 17 case studies featured in a report written by the Georgetown Climate Center, Managing the Retreat from Rising Seas: Lessons and Tools from 17 Case Studies.
