The Harold J. Miossi Charitable Trust has awarded grant funding to Creek Lands Conservation and ECOSLO, with in-kind support from the City of San Luis Obispo, to support restoration of the Downtown corridor of San Luis Obispo Creek, between Chorro and Nipomo Streets. The project will focus on restoring native riparian habitat and ensuring long-term stewardship of this highly visible and beloved stretch of SLO Creek.
San Luis Obispo’s historical development is closely tied to the creek that runs through its heart. Like many urban waterways in California, SLO Creek once served as both a water source and a means of waste removal, while also posing periodic flood risks. In the 1960s, community members, led by students from Cuesta College and Cal Poly, helped spark a shift in how the creek was valued. They convinced local businesses that transforming the polluted waterway into a welcoming creek-side walking area near Mission Plaza would strengthen downtown foot traffic and commerce.
“ECOSLO was founded in response to the November 1969 ‘Fish Kill,’ when over 50,000 fish died in San Luis Obispo Creek, inspiring local students and residents to take action,” said Kendra Paulding, ECOSLO’s Executive Director. “What started as a grassroots effort has grown into decades of protecting our local habitats, and we’re proud to continue the fight for healthy habitats in SLO.”
More than 50 years later, the Harold J. Miossi Charitable Trust is investing in the future of San Luis Obispo by helping restore key sections of SLO Creek, beginning in the city’s historic core. The SLO Creek Downtown Restoration Project is a science-based partnership between Creek Lands Conservation, ECOSLO, and the City of San Luis Obispo. Restoration activities include removal of invasive non-native plants, re-establishment of native riparian vegetation, and strategic tree planting to enhance habitat quality, biodiversity, and the overall visitor experience.
Planned enhancements include interactive educational signage and docent-led walks to help residents and visitors better understand the ecological and cultural significance of SLO Creek. The project will be implemented over three years, from Spring 2026 through Spring 2029.
“Our objective is to ensure that SLO Creek remains a cherished community asset for generations to come,” said Don Chartrand, Executive Director of Creek Lands Conservation. “This project improves habitat while strengthening people’s connection to the creek and inspiring long-term stewardship.”
