What We Do

The Open Space Authority offers nature-based solutions to growth and climate change, protecting open spaces, wildlife habitats, trails, water resources and agricultural lands. We connect people to nature through accessible preserves, free nature events and guided activities, environmental education and a robust Urban Grant program, while engaging communities through volunteer programs, partnerships and more.

Investing in Nature

The Open Space Authority is funded primarily through a $24 per year parcel tax (referred to as Measure T) and a $12 per year parcel benefit assessment (referred to as District 1) to help make the benefits of nature available to all. For every $1 invested in nature, we leverage $3 in public and private partnership funds for conservation, restoration and recreation projects.
