What Riverbanks Society does
Mission
The Riverbanks Society is a south carolina corporation organized to provide financial support for the richland-lexington riverbanks park district and its activities.
As stated on its FY2025 Form 990.
Programs
The society functions solely to support the efforts of riverbanks zoo and garden, a governmental entity that owns and operates a public zoo and botanical garden. The society provides funds to riverbanks derived from membership sales and fundraising efforts. Funds provided supplement and enhance the value and offerings of the zoo and garden. The society makes additional small grants to further conservation efforts when so directed by riverbanks.

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 $17M to $7.8M (−54%).
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.
94% of RIVERBANKS SOCIETY’s revenue is contributions — more reliant on donations than three-quarters of its peers (74% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 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.
Who funds it, year by year
2017 → 2023: the base broadened from 4 funders to 8 funders, grant income rose $44k → $109k.
8 of 20 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 5% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

How long its funders stay
50% of RIVERBANKS SOCIETY's funders are still giving 3 years after their first grant; 80% 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
97% of RIVERBANKS SOCIETY's grant income comes from South Carolina funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $511k arriving through sponsors registered in 8 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.
