Learn About OurCounty Actions led by the Chief Sustainability Office

The Chief Sustainability Office serves as the County lead for implementing a select sub-set of the actions outlined in the OurCounty sustainability plan. Learn about some of our ongoing implementation efforts below.

Climate Vulnerability Assessment

In 2019, OurCounty Sustainability Plan stakeholders identified the completion of a countywide Climate Vulnerability Assessment (CVA) as a top priority for plan implementation, as noted in the FY 2019/2020 Priorities Report. The Chief Sustainability Office is leading the assessment process and collaborating with a wide range of partners to complete it.

The CVA will examine the county’s social and physical vulnerability to climate hazards such as extreme heat, wildfire, and flooding — which are projected to become more severe in the coming decades. The final CVA report will highlight equity implications of the assessment findings, including how climate vulnerabilities are distributed across different communities and sub-populations within the county. CVA findings will guide a range of climate adaptation, emergency preparedness, and community resiliency efforts.

How to get involved:

The assessment process kicked off in the October of 2020 and is anticipated to be completed by summer 2021. CSO held a public workshop at the beginning of the assessment to gather initial input, and will hold a second public workshop in July to share draft findings and gather feedback. Sign up for our newsletter or follow us on social media to receive updates.

CSO has also engaged a wide variety of stakeholders in the assessment process through key informant interviews and small group discussions. The engagement process and findings will be outlined at the public workshop and in the final report.
