Supervisor Hilda L. Solis Leads Effort to Protect San Gabriel Valley Mountains National Monument

The San Gabriel Valley Mountains are a County treasure that spans over 340,000 acres of land. Open spaces create a unique and special quality of life, and in that spirit, today the Board of Supervisors passed a motion, authored by Supervisor Hilda L. Solis, to save this National Monument following President Trump’s recent executive order re-examining national monuments created since 1996. Approximately 25 currently designated monuments are potentially impacted.

“The San Gabriel Mountains are visited by millions of people that come from near and far to enjoy this breathtaking natural gem. The designation of a National Monument was meant to preserve and enhance the natural, historic, and scenic resources of the San Gabriel Mountains and the valley,” said Supervisor Hilda Solis. “Many community organizations and advocates were instrumental to the appointment of the Mountains as a National Monument. We cannot have decades of hard work signed away with a stroke of a pen.”

During her time in Congress, Supervisor Solis was a leading advocate to preserve the San Gabriel Mountains, ensuring a designated stream of funding that would enhance conservation efforts and improve hike trails, install restrooms, and provide other amenities to allow future generations to enjoy the Mountains.

Today’s motion is another step forward in the Supervisor’s efforts to protect this National Monument. This motion directs the County’s D.C. Legislative Advocates to send a five-signature letter to the Los Angeles County’s congressional delegation, requesting support and legislation to protect the National Monument status of the San Gabriel Mountains as designated by then-President Barack Obama in 2014.

“We strongly support the protection of all national monuments and the San Gabriel Mountains. Thank you Supervisor Solis for your leadership in Congress,” said Amy Wong, Coalition Coordinator for the San Gabriel Mountains Forever. “These mountains represent 70% of our open space in the County and 30% of our drinking water. An attack on one national monument is an attack on all national monuments.”
