Rio Hondo Group News

What is the Rio Hondo Group?

Many of you may be wondering what the Sierra Club Rio Hondo Group is. The Angeles Chapter of the Sierra Club, which consists of Los Angeles and Orange Counties, is broken down into 16 geographic groups. The communities composing the Rio Hondo Group are Brea, Diamond Bar, Rowland Heights, Hacienda Heights, Fullerton, La Habra, La Habra Heights, Buena Park, La Mirada, Norwalk, Pico Rivera, Downey, and Whittier. Most of these communities are near the Puente / Chino Hills and are in both Los Angeles and Orange Counties.

Because of its proximity to the Puente/Chino Hills, many of the group's conservation activities involve the hills. The group is active in the Puente/Chino Hills Task Force, which is working to preserve the wildlife corridor running from the western edge of the hills in Whittier to the Cleveland National Forest near the 91 Freeway. The group has also been involved in efforts to save West Coyote Hills in Fullerton and sponsors outings in the local area.

The Rio Hondo Group has meetings on the second Monday of every month except December. Our meetings alternate between excom meetings which deal with group level decision-making, and general meetings which are open and generally feature a guest speaker on varied topics such as trips, the environment, native plants, hiking, etc. Please check this web site for upcoming activities.

Welcome to our new members in Hacienda Heights, Rowland Heights, and Diamond Bar!

In April, 2018 the Angeles Chapter Executive Committee added Sierra Club members in zip codes 91745, 91748, and 91765 to the Rio Hondo regional group. We invite you to join in our local outings and meetings in Brea and, if you are interested, to volunteer on one of our committees.

Group Activities - Rio Hondo Group is active with the local Sierra Club political and conservation committees in addition to our outings and monthly programs.  We could use more volunteers who like our activities and would like to help protect our environment. Please join us by contacting an Executive Committee member or attending one of our meetings.

Political Action News


The national election had some pretty amazing results for the Angeles Chapter and its political endorsements.  Every one of these victories puts someone in Congress who believes that climate change is real, and intends to address it. After the votes were certified in California it appears that all 6 of our endorsements for state offices were elected, all 19 of the Congressional races within the Angeles Chapter were won by our endorsed candidates, 18 of the 19 candidates we endorsed for State Assembly won, and 5 of the 7 endorsees for State Senate won.

The changes could clear the way for new mining, oil and gas drilling, and development . . .
