Organized community input and public participation on behalf of New York State through the New York Rising Community Reconstruction Program - aiming to provide rebuilding and revitalization assistance to communities damaged by Hurricane Sandy and Irene and Tropical Storm Lee. Specifically Sustainable Long Island worked as part of a consultant team focusing on the areas of Oceanside/Island Park/Harbor Isle/Barnum Island; The City of Long Beach; Lido Beach/Point Lookout; and The Village of Atlantic Beach/Atlantic Beach Estates/East Atlantic Beach.
The first program described on its most recent Form 990-EZ.

From the IRS filings of Sustainable Long Island Inc’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.

Sustainable Long Island Inc leans on a few funders — its largest provides 100% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% 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 Sustainable Long Island Inc.
Largest funder’s share by year: 2017 100% · 2020 100% — broadly stable.
“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.
Where its funders are
100% of Sustainable Long Island Inc's grant income comes from New York funders.
Funder states come from each funder’s own filing. $5 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.
