Our Team

In early 2020, Len Materman was appointed CEO of the San Mateo County Flood and Sea Level Rise Resiliency District, also known as OneShoreline. OneShoreline was established by State legislation on January 1st of that year as the first independent government agency in California focused on planning for and reducing the impacts of climate change on a region. These impacts have already proven to be substantial and, in key respects, will exceed those of all other California counties.  

Len recently served as the first Public Policy Practitioner in Residence at Stanford University’s Center for the American West and, together with colleagues at Stanford and UC Berkeley, he was a contributing author of two recent books on financing and implementing large-scale climate resilience. Previously, Len led a regional government agency on the San Francisco Peninsula that completed the largest multi-jurisdictional sea level rise protection effort in the state for which the agency was highlighted as a model in the Wall Street Journal, Los Angeles Times, and other major media outlets. 

Prior to his work in regional government, Len consulted to the U.S. State Department and foundations and nonprofits around the world, and he served as executive producer of a nationally-broadcast PBS documentary. During the Clinton Administration, Len served as an advisor to the Director of FEMA and as FEMA’s representative on two White House Task Forces. Before working in Washington DC, Len was the Director of Government Affairs at UC Berkeley, where he received two Chancellor’s Distinguished Service Awards. He has spoken on a range of topics at conferences from Hawaii to Chernobyl and many locations in between, and he has degrees in Political Science and Biology from UC Davis.

Lucy Dong is the Director of Finance and Administration for San Mateo County Flood and Sea Level Rise Resiliency District (OneShoreline), where she provides the financial and operational leadership critical to advancing the agency’s vital mission.

Johnathan Perisho is a Project Manager for the San Mateo County Flood & Sea Level Rise Resiliency District (OneShoreline). He has over a decade of experience working to support resilient natural systems through diverse projects including regional planning, site design and installations, pilot strategy development and monitoring, community engagement, policy, and land management.

Previously, Johnathan served as a project manager with the Watershed Conservation Authority, a state and local government JPA with territory across Los Angeles and Orange counties where he advanced multi-jurisdictional watershed planning and development for stormwater management, parks, open space, and trails. With The River Project he partnered with both the City and County of Los Angeles on residential retrofit projects for water capture, conservation, and reuse leading to development of standard plans with City of LA Bureau of Engineering, and on plans and initiatives as Design & Policy Director.

Johnathan has degrees in landscape architecture from Cal Poly Pomona and Ball State University.

Kevin Murray is a water resources professional with over 20 years of experience in planning and implementing complex, multi-benefit projects.  He worked in the public sector in San Mateo and Santa Clara Counties for the first two decades of his career, before joining a private consultant firm in Sacramento in 2024, where his work was focused primarily on the San Joaquin River system, leading the development of a Comprehensive Mitigation Plan for a suite of U.S. Army Corps of Engineers flood protection projects, and the development of riparian and freshwater marsh restoration design in the San Joaquin River National Wildlife Refuge.  Kevin was appointed Chair of the Western Region of the Bay Area Integrated Water Management Program in 2009 and has been awarded a Congressional Certificate of Special Recognition from the United States House of Representatives for “Outstanding and Invaluable Service to the Community.”  Kevin joined OneShoreline in 2026 to manage infrastructure maintenance and the flood early warning system.

With more than 15 years of experience working at the intersection of water, climate, and community, Clare Keating brings a collaborative and systems-oriented approach to her role as Project Manager at OneShoreline. Her work spans complex, multi-hazard resilience initiatives across California and internationally, addressing interconnected challenges including sea level rise, flooding, drought, water quality, and extreme heat. She has worked across public agencies, nonprofits, and private-sector partners, including work with the California Department of Water Resources, the U.S. Army Corps of Engineers, Fortune 500 companies, and global conservation organizations.

Her career reflects a consistent focus on water systems—from marine conservation and sustainable conservation finance to statewide drought resilience and water stewardship. In prior roles at Earth Genome and Arcadis, she led decision support tool development, planning efforts, and multi-benefit adaptation strategies that help agencies, utilities, and communities navigate uncertainty and align around action.

At OneShoreline, Clare supports regional shoreline adaptation planning. Shoreline resilience is both a natural progression of her work and a longstanding personal and professional focus.

Clare holds an Executive MBA from Brown University and IE Business School and a Master of Commerce in Environmental Economics from Rhodes University.
