Mission Plaza

November 14th SLO Creek Restoration!
The SLO Creek Restoration Project at Mission Plaza is a three-year community-driven effort led by ECOSLO in partnership with Creek Lands Conservation and the City of San Luis Obispo.
This collaborative restoration initiative focuses on revitalizing a key stretch of San Luis Obispo Creek that flows through Mission Plaza—one of the city’s most visible and cherished public spaces.
Throughout the project, volunteers will help remove invasive plant species that threaten native habitat, implement erosion control measures to stabilize creek banks, and plant a diverse mix of riparian native plants and trees. These efforts will improve water quality, enhance wildlife habitat, strengthen bank stability, and restore the ecological health of the creek corridor.
ECOSLO will coordinate quarterly volunteer workdays over the next three years, creating consistent opportunities for community members to participate in hands-on environmental stewardship. By combining ecological expertise with community engagement, this project aims to create a cleaner, more resilient creek ecosystem that will provide lasting environmental and educational benefits for years to come.
This event is made possible by the Harold J. Miossi Charitable Trust!

SLO County Library
995 Palm Street, San Luis Obispo
Question the Cup: The Truth About Compostable Plastics in SLO County
That compostable cup might not be as green as you think!
Join ECOSLO for an educational presentation exploring what compostable plastics are, how they're made, and why they should go straight to landfill instead of becoming compost in San Luis Obispo County. We'll begin with an introduction from Nia Starr, Sustainability Coordinator at ECOSLO, who will break down the differences between conventional plastics, bioplastics, and compostable plastics, including the materials they're made from and what it actually takes for them to break down. Ashley Kuder from the San Luis Obispo County Integrated Waste Management Authority (IWMA) will explain how our local green waste collection and processing systems work, what materials are accepted in green bins, and why compostable plastics cannot be processed through our local system.
Come with questions and leave with a better understanding of greenwashing, waste disposal, and how to make more informed choices about sustainable packaging.
