Tres Hermanos Ranch-testTres Hermanos

Diamond Bar City Council is strongly opposed to Industry’s plans to build a massive solar facility on the Tres Hermanos 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. Diamond Bar has filed several lawsuits to protect the interest of the City and its residents challenging 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. City of Chino Hills has filed similar lawsuits. Read More

Sycamore Canyon Park Slope Erosion RepairSycamore Canyon Park Slope Erosion Repair

A series of powerful winter storms in mid-January 2017 triggered flooding, mudslides, and other destructive damage throughout California.

The slope failure undermined two of the four tiers of stairway that lead to the trail, rendering access unsafe. The County of Los Angeles, State of California, and federal government declared a local state of emergency, making the cost of the repairs associated with these severe storms eligible for reimbursement from the Federal Emergency Management Agency.
