What is Sustainable Foster City? It's the holistic strategy that seeks to protect, maintain, and grow the economic and natural resources in Foster City and allow all community members to pursue an enhanced quality of life. The strategy is based on the principles of sustainability, which focuses on three components: the stewardship of and respect for the environment and natural resources of a community; increasing and deepening the social equity among people in the community, including the education and health; and strengthening the economic and financial prosperity of the community, or simply stated, Economic Development, Environmental Sustainability, and Social Equity and Engagement.
