Our new Sustainability Dashboard captures performance on 30 sustainability metrics for all 20 cities in San Mateo County and the county’s unincorporated areas in 11 categories: Agriculture and Food, Built Environment, Energy, Climate Action, Ecology and Biodiversity, Economy, Health and Well-Being, Social Equity, Transportation, Waste Management and Water.

Data often lags behind the year it’s available, and the metrics shown represent results tallied in 2019, 2020 and 2021. The sources of data are shown on each data display and on each spreadsheet. Realizing that local jurisdictions have made progress since then, we have offered all cities the opportunity to include a short narrative to explain results and provide some context. We look forward to comparing progress when we collect data again.

Affordable Housing

The Regional Housing Needs Assessment (RHNA) is state-mandated assessment of future housing needs for all income levels within a region, conducted every eight years. Every jurisdiction (city or unincorporated county) within the region must plan for its RHNA allocation in the Housing Element of its General Plan. The Association of Bay Area Governments (ABAG), a regional planning agency incorporating local governments in the nine Bay Area counties, including San Mateo County, offers a variety of tools and resources via its Regional Housing Technical Assistance (RHTA) Program to support jurisdictions as they complete their Housing Element updates. You can contact ABAG directly at housingta@bayareametro.gov to learn more.

For more information about Housing Element compliance incentives as well as noncompliance consequences, please see this one-page document from ABAG.
