Managing the Retreat from Rising Seas — San Diego, California: ReWild Mission Bay

In San Diego, California, the city and various stakeholders are evaluating different land-use and planning alternatives to conserve and restore migrating wetlands in Mission Bay as a part of local decisionmaking processes. Mission Bay in San Diego was previously a 4,000-acre wetlands complex located near the mouth of the San Diego River. Since the 1950s and 60s, Mission Bay’s natural resources have been altered by climate change and human activities, and today only one percent of the original wetlands — 40 acres — remain.

To conserve and restore Mission Bay, San Diego Audubon and other partners started an initiative called “ReWild Mission Bay” that evaluated different alternatives for protecting wetlands through a feasibility study. One of the feasibility study’s alternatives aims to relocate Campland on the Bay, an existing RV campground on land owned by the city, inland. By moving Campland on the Bay inland, the city could address wetland migration while providing community resilience and environmental benefits. The alternative to relocate the location for Campland on the Bay, if implemented, would be aligned with and build on other local planning efforts to convert a part of the surrounding Mission Bay Park into a regional amenity that accommodates both public and private uses.

In July 2019, the San Diego City Council approved a lease extension and expansion for Campland on the Bay that has delayed any potential implementation of the ReWild Mission Bay wetland alternatives until after the term of the lease expires. Proponents of the City Council’s decision are in favor of maintaining this existing land use to support the maintenance of affordable travel accommodations. The ongoing work in Mission Bay can serve as an example for other coastal jurisdictions addressing the tradeoffs raised in land-use and planning efforts for coastal retreat and the challenges that can arise in balancing competing stakeholder interests to achieve both human and environmental priorities. ReWild Mission Bay also shows how nongovernmental stakeholders can conduct planning processes to help government agencies make decisions about long-term land uses and restoration activities.

  

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. Each case study tells a different story 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.
