San Juan Bay Estuary Program Assesses Vulnerability and Targets Adaptation Measures
The Puerto Rico Climate Change Council brought together numerous experts in 2010 to assess potential climate impacts and vulnerability in Puerto Rico’s State of the Climate Report. Among numerous climate risks, the report details several climate threats to the San Juan Bay Estuary Program, one of 28 National Estuary Programs (NEPs) from around the country. Active members of the Puerto Rico Climate Changes Council, the San Juan Bay Estuary Program (SJBEP) decided to follow-up the report with a risk determination and vulnerability assessment for the San Juan Bay estuary. SJBEP worked with the EPA’s Climate Ready Estuary Program to undertake a comprehensive vulnerability assessment and identify adaptation strategies. SJBEP used the EPA’s Being Prepared for Climate Change Workbook process to catalog climate related vulnerabilities through community workshops, stakeholder meetings, and exercises.
In order to better understand climate concerns and experiences, SJBEP engaged the environmental justice communities that live and work around the bay through workshops and on-site discussions. The completed vulnerability assessment better prepares the San Juan Bay Estuary Program to undertake action to adapt to a changing climate. The report represents a first step for the SJBEP. The vulnerability assessment will help inform the development of a future adaptation plan that identifies appropriate adaptation strategies. Meanwhile, the vulnerability assessment has encouraged the estuary program to pursue measures to improve the resiliency of coastal wetlands and coral reefs.
|How Did They Do It?||Applicable EPA Tools|
|Conducted vulnerability assessment with extensive stakeholder engagement process
Being Prepared For Climate Change Workbook helps develop a vulnerability assessment and risk-based climate change adaptation plan to reduce the most pressing risks.
|Identified highest likelihood and highest consequence risks for non-point and point source pollution
EPA Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) can help users create climate scenarios and assess the coupled effects of climate and land-use change on water quality.
|Used this information to inform management plans and implement resiliency measures
Synthesis of Adaptation Options for Coastal Areas Guidebook can assist in identifying adaptation options to protect coastal areas from storm surge and inundation concerns.

San Juan utilized climate projections to determine the threat likelihood and vulnerability of climate risks. To see another example of how a coastal community assessed downscaled vulnerability to potential climate threats view the Southwest Florida Salt Marsh Vulnerability and Adaptation Plan. Many coastal communities in the pacific islands and elsewhere may also have to deal with other challenges including saltwater intrusion and sea level rise; for another coastal sea level rise case, view MD SLAMM Model.
