After years of fierce debate, a large-scale Southern California development project seems to have finally moved past its tallest hurdle: protecting one of the world\u2019s oldest trees. Jurupa Valley, the Riverside County city of more than 100,000, in the sprawling Inland Empire east of Los Angeles, has been bitterly divided for years over the fate of a specific Palmer\u2019s oak that rests in a rocky wash of (currently) open land. The tree, thought to be at least 13,000 years old, is not only historic; it\u2019s also considered culturally vital to the Gabriele\u00f1o Band of Mission Indians\u2019 Kizh Nation.<\/p>

Rio Vista, an incoming residential and light industrial development near the base of the Palmer\u2019s oak, has drawn loads of local dissension during public comments and meetings over the past several years. The project, spread across some 918 acres, calls for around 1,700 residential units, as well as a business park, a new school and other community additions like parkland and open space.<\/p><\/div>

At its closest, the business park would come within 450 feet of the tree.<\/p><\/div>

Some in Jurupa Valley, including anti-development groups and preservation-minded nonprofits, argued that the large project would not only encroach on the tree\u2019s needed habitat but that the resultant underground water use could kill the tree entirely. The Palmer\u2019s oak species, Quercus palmeri, is known for its low height, prickly leaves and ability to grow as a scraggly, almost bush-like tree in arid regions. Like the King Clone that clings to life out in the Mojave Desert, Palmer\u2019s oaks use deep and widespread roots to stay in place and take in whatever water may be available.<\/p><\/div>

In 2024, a consortium of groups, including the Center for Biological Diversity, sued the city of Jurupa Valley in an effort to better protect the historic Palmer\u2019s oak, which the center says is perhaps the oldest known living plant in the state of California. The groups called for a 100-acre preserve to be maintained around the site of the tree.<\/p><\/div>

Now, some 18 months later, city and conservation groups have come to an agreement on a slightly reduced plan, with almost 55 acres of open space set to be protected around the ancient tree. The development\u2019s nearest border will also be moved from 450 feet out to 1,000 feet away from the Palmer\u2019s oak. As part of an earlier agreement, the Kizh Nation will receive 500 acres of land in the same area.<\/p>

Development has been a\u00a0flashpoint for many Inland Empire communities in recent years as warehouses and fulfillment centers spring up alongside new housing, often in what was once arid and rural or semi-rural land. Some communities have embraced the growth, citing the need for affordable housing and jobs, while others have cautioned against development on cultural and ecological grounds, arguing at times that large developments can further exacerbate climate and public health issues.\u00a0<\/p><\/div>

\u201cI\u2019m relieved that we can steer development away from an oak that\u2019s so special it can\u2019t be found anywhere else in the world,\u201d said Aruna Prabhala, a senior attorney at the Center for Biological Diversity, in a news release. SFGATE reached out to the mayor and mayor pro tem for the city of Jurupa Valley, as well as Rio Vista\u2019s developer Richland Communities, but did not hear back before publication.\u00a0<\/p><\/div>
