What The Horse Park at Woodside does
Mission
Unite community in shared purpose and connection for land conservation, equestrian sport, lifelong learning and fun.
As stated on its FY2025 Form 990.
Programs
The Horse Park at Woodside is a 501(c)(3) not-for-profit organization grounded in four mission pillars: horse sport, land stewardship, lifelong learning and community engagement. The park provides educational, recreational and competitive equestrian offerings that encourage the growth and development of youth and adults. The park's full use annual memberships (individual, family and farm options) and annual access day use memberships (individual) grant access to equestrian amenities such as arenas, the cross-country course, the exercise track and trails. The community membership (non-equestrian) allows individual access to enjoy park public spaces and trails. The park provides equestrian membership discounts to support educational programs such as the us pony club. We currently have ~800 memberships.

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.
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 $6.5M to $9.3M (+43%).
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: 2021 6% · 2022 5%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

From the IRS filings of THE HORSE PARK AT WOODSIDE’s funders (the co-funder graph). 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
THE HORSE PARK AT WOODSIDE leans on a few funders — its largest provides 57% of grant income and the top three 81%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
93% 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 THE HORSE PARK AT WOODSIDE.
Largest funder’s share by year: 2017 44% · 2018 94% · 2019 77% · 2020 37% · 2021 41% · 2022 62% · 2023 74% — 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
70% of THE HORSE PARK AT WOODSIDE's funders are still giving 3 years after their first grant; 78% 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
93% of THE HORSE PARK AT WOODSIDE's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $423k that is directly attributable, 75% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $5.3M arriving through sponsors registered in 9 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.
