Code for the Planet: San Francisco

Participants will work in small, mentored teams with California watershed, GIS, and environmental-monitoring datasets to prototype open-source tools that support water replenishment, fire stewardship, community-led research, and public-sector decision-making. Technical and non-technical participants are welcome, with mentors supporting engineering, cybersecurity, program management, design, storytelling, and open-source collaboration. Projects will be developed in shared repositories with documented data sources, methods, and deployment guidance so that public agencies, Tribal partners, researchers, and environmental organizations can continue adapting the work after the event. Example project tracks Environmental GIS: Use responsible AI and prompt engineering to make California stewardship and Tribal GIS data easier to map, interpret, and use. Water and fire stewardship: Build open-source monitoring and decision-support tools for water replenishment, watershed health, wildfire risk, and land restoration. Secure open-source infrastructure: Prototype cybersecurity workflows and reusable reference architectures for environmental tools used by public-sector and community organizations. Why attend Learn how AI, GIS, open data, and cybersecurity can support environmental stewardship Contribute directly to open-source projects with real public-interest applications Work alongside engineers, educators, community organizations, and Tribal partners Hear from environmental, responsible AI, and public-sector technology leaders Explore pathways into civic technology, environmental monitoring, and open-source careers Meet students, builders, mentors, and community-rooted organizations across Oakland and the East Bay Students, emerging technologists, educators, designers, engineers, storytellers, nonprofit teams, and members of the general public are encouraged to participate. No prior open-source experience is required. Free to attend. The event will include live captions, wheelchair-accessible space, livestream access, and a quiet breakout area. 🕰️ Program Agenda: 9-9:30am: Check-in + breakfast 9:30-10am: Welcome + challenge overview 10-10:30am: Agency and environmental dataset presentations 10:30-11am: Project tracks walkthrough 11-11:30am: Technical onboarding 11:30-12pm: Team formation 12-3pm: Build session 3-4pm: Mentor support + project refinement 4-5pm: Project demos Check out our recent hackathons ✉️ Email any questions to [email protected]
