BACKGROUND INFORMATION -

Where is the Property Located?Map of Tres Hermanos
Tres Hermanos Ranch is 2,450 acres of undeveloped open space located within the cities of Diamond Bar and Chino Hills. Approximately 730 acres, or 30 percent of the property, is within Diamond Bar city limits; the remaining 1,720 acres are located in Chino Hills. The portion of land within Diamond Bar is located north of Grand Avenue and is visible from Diamond Ranch High School.

Who Owns the Property?
Tres Hermanos Ranch is currently held in trust by the Successor Agency to the Industry Urban Development Agency on behalf of all the taxing entities, which include the cities of Diamond Bar and Chino Hills, and the County of Los Angeles.

According to a City of Industry memorandum, the Property was owned by the City of Industry but transferred to the former Industry Urban Development Agency in the late 1970s.

Under the Redevelopment Dissolution Act of 2011, the Oversight Board is charged with and has a fiduciary responsibility to maximize the value of the property for the benefit of various taxing entities, which includes Diamond Bar, Chino Hills, and other public agencies.

At its meeting of August 24, 2017, the Oversight Board approved the Successor’s Agency’s sale of the Tres Hermanos property to the City of Industry.

What is the Proposed Use of the Property?
As recent as October 2017, Industry City Manager stated in writing that the City does not have any definitive plans for the future use of Tres Hermanos. However, an agenda item currently before the Industry City Council seeks to ratify a Master Ground Lease and four amendments for a 450 megawatt solar generating facility on the property.

What is the City's Position?
The City Council is strongly opposed and deeply concerned with the Oversight Board’s decision to approve the sale of Tres Hermanos Ranch to Industry, and the lease agreement between Industry and a private entity to develop a solar generating facility on the property.

Compounding this concern is mounting evidence of flagrant and repeated violations, inconsistencies and contradictions on the part of the Successor Agency, the Oversight Board and the City of Industry with regard to actions taken in relation to the Tres Hermanos property and the proposed development.

Misinformation and Misconceptions

Existing Land Use Designation: Falsehoods and exaggerations have been circulating regarding the number of housing units permitted on the Diamond Bar portion of the Tres Hermanos property. Only 30 of the 720 acres within Diamond Bar’s jurisdiction is designated high density residential. The remaining 690 acres are zoned either agriculture or very low density – one residence per five acres.

Phone Poll: Several individuals have reported receiving calls from an organization conducting a survey that appeared to be aimed at gauging knowledge and opinion, and even influencing support for the development of the solar project on the Tres Hermanos property. According to the reports, the narrative provided and questions asked as part of this poll were clearly biased and misleading.
