What Marin County Bicycle Coalition does

As stated on its FY2025 Form 990.
Programs
SAFE ROUTES TO SCHOOLS PROGRAM: MCBC's Safe Routes to Schools program empowers thousands of Marin students and families to walk and bike safely through hands-on bicycle education, traffic-safety instruction, encouragement events, and family engagement. Working in partnership with public and private schools, we provide age-appropriate training, assemblies, workshops, rodeos, and volunteer-supported activities that build lifelong healthy transportation habits. Our team also surveys travel patterns, produces educational materials, and collaborates with local agencies to improve the safety of routes to and from school--helping reduce traffic, increase youth confidence, and make every trip to school safer and more joyful.
$666,915 spent64% of program spendingCORY'S RIDE: Cory's Ride removes barriers to cycling for Marin youth by providing bikes, gear, training, mentorship, and community-building experiences for students who otherwise lack access to safe, reliable transportation. Participants receive ongoing instruction, leadership development opportunities, and support to confidently ride to school, work, and activities. Centered around empowerment and equity, the program helps young people build independence, improve fitness, strengthen social connections, and open new pathways to education and opportunity. Cory's Ride reflects MCBC's belief that every young person deserves the freedom and benefits that bicycling can bring.

We help agencies plan and implement bike/pedestrian projects, advise on master plans, and advocate for infrastructure that provides riders of all ages and abilities. Our team analyzes project proposals, mobilizes community input, and brings forward data-driven recommendations that improve intersections, corridors, and transit access. Through outreach, education, and public engagement, we champion a transportation system where choosing to bike is safer, easier, and more accessible for everyone.

We promote responsible riding, support trail maintenance and restoration projects, and champion new opportunities for family-friendly and beginner-accessible routes. Through community events, educational programming, and collaborative planning efforts, MCBC strengthens the connection between people and nature while protecting environmental resources. Our work supports a thriving trail community and ensures Marin remains a national model for balanced, sustainable recreation.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $401k to $553k (+38%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 46% · 2018 44% · 2019 40% · 2020 40% · 2021 30% · 2022 5% · 2023 5% · 2024 6% · 2025 13%. Grants only. Government contracts and fees sit inside program revenue.
63% of MARIN COUNTY BICYCLE COALITION’s revenue is contributions — more donation-reliant than the typical peer (48% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 9 funders to 21 funders, grant income rose $86k → $384k.
9 of 38 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 46% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of MARIN COUNTY BICYCLE COALITION’s funders (the co-funder graph). Top 30 of 38 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
MARIN COUNTY BICYCLE COALITION has a broad base — no single funder exceeds 22% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
68% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund MARIN COUNTY BICYCLE COALITION.
Largest funder’s share by year: 2017 29% · 2018 23% · 2019 34% · 2020 19% · 2021 28% · 2022 34% · 2023 39% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
43% of MARIN COUNTY BICYCLE COALITION's funders are still giving 3 years after their first grant; 66% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
MARIN COUNTY BICYCLE COALITION draws 52% of its grant income from funders outside California, across 11 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $775k arriving through sponsors registered in 7 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
