History

2021
2021
In September 2021, the Open Space Authority received multiple funding awards totaling over $16 million from the State of California for the protection of North Coyote Valley open space lands. One month later, the Open Space Authority and partners permanently protected sixty acres of prime farmland in the middle of Coyote Valley to establish sustainable, local climate-smart agricultural practices within the Coyote Valley Conservation Program Area. In November 2021, San José City Council voted unanimously to approve zoning changes to Coyote Valley that will protect it from urban sprawl. And in the following month, the Santa Clara County Board of Supervisors voted unanimously to strengthen protections for Coyote Valley’s natural and working lands through amendments to the County's General Plan, zoning ordinance, and zoning map. These collaborative actions prioritized Coyote Valley for agriculture, open space, and natural resources protection over sprawl development.
