Reflections on OneShoreline’s First 5 Years

Over the past decade, it has become increasingly clear that climate change presents a transformative challenge for San Mateo County. Our region has already been severely affected by drought, wildfire, extreme storms, and coastal erosion. Sea level rise threatens more people, property, and infrastructure here than in any other county in California. Recognizing the urgency of these challenges, all 20 cities and the County came together in 2019 to support State legislation establishing the first climate-focused government agency in California – the San Mateo County Flood and Sea Level Rise Resiliency District, better known as OneShoreline – and committed three years of start-up operating funds. With this unified financial and political support, OneShoreline opened its doors five years ago this month.

While it was envisioned that we would focus on aligning and building resilience to future conditions, two needs quickly caught our attention: addressing flooding caused by atmospheric rivers and ensuring that new private development and public infrastructure projects incorporate resilience. Our priorities reflect all these challenges, and because they are increasing, we are obliged to secure stable funding to both continue this work long-term and leverage outside funding.

To achieve resilience, we must plan for it together. Following a public process that received over 500 comments from public agencies, private developers, engineers, environmental organizations, and community members, in June 2023 the OneShoreline Board adopted Planning Policy Guidance to Protect and Enhance Bay Shoreline Areas of San Mateo County. We applaud the cities that have chosen to incorporate portions of this template text into their general plans, specific plans, zoning ordinances, and development agreements, and we strongly encourage all cities to update their policies so that new developments can function for their intended lifespan and contribute to community resilience without having to undergo costly retrofits in the future. Other key assets that make our communities livable are stormwater and wastewater systems, roads, parks, marinas, and utilities. Like private developments, these need to be planned with future conditions in mind yet are largely still planned by looking in the rear-view mirror. To address this, OneShoreline is now developing a countywide Planning Policy Guidance for Resilient Public Infrastructure. New climate data and staff from multiple agencies will contribute to the development of this document, which we intend to release for public comment this fall and bring to OneShoreline’s Board for adoption early next year.

A core concept behind the creation of OneShoreline five years ago and our work since then – that all of us are in this together – is relevant whether resilience is built near Highway 1 along the Pacific, Highway 101 along the Bay, or Skyline Boulevard through the hills. While there are several resilience projects underway or even completed, some of which are listed on the Projects page of our website, a new State requirement aims to ensure multi-jurisdictional coordination through guidelines established by the California Coastal Commission and Bay Conservation and Development Commission (BCDC). While this may seem like a concern only for our shoreline communities, in reality it has far-reaching implications for anyone who drives on one of these highways, relies on PG&E’s electrical or natural gas transmission lines, utilizes water from the SFPUC, or sends waste to a water treatment plant. For cities that wish to meet this requirement and align with their neighbors, OneShoreline is here to help. Last month, we applied for grant funding to do this planning on behalf of two cities and we are in discussions with several other cities at this time. 

As this newsletter arrives in your inbox, we are about to experience a few days of precipitation. While (so far) this winter has brought relatively little rain, we all know that a single atmospheric river, especially one coinciding with a high tide, can flood our streets, businesses, and homes. OneShoreline is helping to address this issue by securing 5-year environmental permits to enable jurisdictions and Caltrans to remove debris from several flood-prone creeks and under roadways, and our Flood Early Warning System and collaboration with the ISeeChange platform for citizen input help to inform storm response as well as resilience project planning.

Thank you for your engagement and support over the past five years. OneShoreline’s mission is to transform the county most vulnerable to the water-related impacts of climate change into the most resilient. This will take all of us working together, and I hope you agree that in five short years, we are off to a good start. As we look ahead, we recognize that much, much more work remains. Your engagement is invaluable, so please reach out to me or OneShoreline’s dedicated Board members with your ideas for how we can build a more resilient region.
