In support of UCLA’s Sustainable LA Grand Challenge, the Center for Climate Science and the UCLA Water Resources Group organized a two-part workshop series investigating how more local stormwater can be harnessed to decrease the Los Angeles region’s dependence in imported water. The workshops were co-hosted by the Institute of the Environment and Sustainability and the Luskin Center for Innovation. Support for the series was provided by the Office of Interdisciplinary and Cross Campus Affairs.

Workshop 1: Understanding Local Stormwater Capture Potential

The first workshop in the LA’s Water Resource Future Series was held on February 19, 2016. UCLA faculty and Los Angeles region region water managers, planners, and scientists explored the state of stormwater management and planning, the potential to connect surface hydrology and groundwater modeling tools to quantify infiltration, potential ecosystem benefits of stormwater capture, and strategies to incentivize increased capture and infiltration of stormwater. The program consisted of talks and panel sessions by invited speakers, each followed by Q&A periods and discussion by all attendees.
