What Altadena Heritage does
Mission
We advocate to preserve the many historic cultural resources of our foothill community and promote thoughtful rebuilding of our business districts and gathering places. Working with the Owen Brown Grave-site Committee through contract with Los Angeles County to create signage, maps, programs, educational materials, a film, and teacher training. Developing programs for community engagement through tours, art contests, lectures, marking important community anniversaries with special events programs, mapping historical context and creating and distributing brochures, newsletters, books, and maps.
As stated on its FY2025 Form 990.

The organization over time
Each line starts at 100 in 2023, so what you read is the shape rather than the size: 150 means half as much again as 2023, 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 2023 to 2024, from $263k to $253k (−4%).
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: 2023 88% · 2024 3% · 2025 87%. Grants only. Government contracts and fees sit inside program revenue.
99% of ALTADENA HERITAGE’s revenue is contributions — more reliant on donations than three-quarters of its peers (64% for the typical peer).
Surplus & reserves

Who funds it, year by year
2021 → 2023: the base held at 1 funder, grant income fell $135 → $85.
1 of 1 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 100% 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 ALTADENA HERITAGE’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.
Where its funders are
100% of ALTADENA HERITAGE'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. Too little is directly attributable to place on a map.
Funder states come from each funder’s own filing. $333 arriving through sponsors registered in 1 state 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.
