Results from the San Diego Regional Climate Assessment Report (2018), part of the California 4th Climate Change Assessment, have been integrated into a case study in Regional Water Planning for Climate Resilience, a recent report by the American Planning Association (APA). The San Diego case study discusses integrated water management practices and multi-hazard planning.
Researchers from the California-Nevada Applications Program (CNAP), a NOAA RISA team, led the San Diego Regional Assessment, one of nine regional assessments in the California 4th Assessment, which appraised vulnerabilities and impacts on multiple sectors throughout the San Diego region. Robert Leiter, a respected planner in the San Diego region and a contributing author of the San Diego Regional Assessment, worked with APA collaborators to integrate Assessment findings into the APA report.
The case study highlights San Diego’s strategies in recent decades to build a more secure water supply in a region with limited local supply from precipitation, high natural climate variability, and possible reductions in local and imported water supplies under future climate change. The case study concludes planners can generate support and understanding of adaptation efforts by fostering community outreach that uses the San Diego Regional Assessment, emphasizing implications for water resources and public safety. Additionally, the San Diego case study advocates stronger collaborations amongst management professionals and integrating climate adaptation and resilience into the region’s Hazard Mitigation Plan. Finally, the case study challenges planners to adopt a “regional greenprint” planning process to protect resources and quality of life in the San Diego region.
