Nancy Steele: Monumental Change in the San Gabriel Watershed

Nancy Steele: Monumental Change in the San Gabriel Watershed

Thursday, April 23, 2015 - 8:30am




Grace T. Black Auditorium, El Monte, CA


The San Gabriel Valley is home to about 1.8 million people and benefits from its proximity to the Angeles National Forest, the headwaters of the San Gabriel River and its 640 square mile watershed. On Oct. 10, 2014, President Barack Obama designated 346,177 acres of existing federal lands, about half of the Angeles National Forest, as the San Gabriel Mountains National Monument. What are the opportunities and challenges that come with the Monument designation?

Other big changes are underway in the Watershed, including transportation investments like the Gold Line Extension that bring development, people and businesses to the Valley compliance planning to meet the new stormwater permit, and the ongoing water supply situation exacerbated by the fourth year of the drought. What does all this mean for the people and wildlife who share the watershed?

This symposium will present opportunities for dialogue on the changes that are coming, and ways of addressing the impacts on social, economic, and environmental health of this large and populous region.
