What City Island Oyster Reef Inc does
Mission
ORGANIZATIONS PRIMARY EXEMPT PURPOSE CIORs mission is to restore the western Long Island Sound ecosystem in order to improve biodiversity, water quality, and coastal resilience by creating reefs of shells to encourage the population growth of the historically abundant oyster and other marine species around City Island. CIOR is building community awareness, promoting active stewardship, developing educational programs, collecting and sharing scientific data, promoting and supporting research, and collaborating with like-minded organizations to achieve this mission.
As stated on its FY2025 Form 990.
Programs
EDUCATION OUTREACH CIOR believes that engaging the community through educational initiatives is an important way to protect the environment into the future. We aim to educate the local community about oysters and their place as a keystone species within Long Island Sounds rich biodiversity.
$108,023 spent72% of program spendingOYSTER REEF CIOR has been funded to select two sites for oyster reefs from five potential locations around the island that were identified by an extensive survey of existing oyster populations around City Island. CIOR monitored the five sites and the data on oyster growth and mortality from those sessions was used to inform the selection of the two sites. The plans and designs for the oyster reefs at those sites are now being presented for sign-off and permitting. Now that the two sites have been selected, specially engineered structures will be put in place, and cured shell material will be added in order to promote reef formation. In addition, CIOR has partnered with local City Island restaurants to collect their discarded shells in 32-gallon bins and bring them to a curing site at the Pelham Bay Landfill. The shells are placed on the grass-covered soil on top of one another to a height of two feet and regularly turned to provide sufficient airflow. No chemicals are used in the curing process, which takes up to twelve months.

The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 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 2022 to 2023, from $8k to $322k (+3974%).
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 7% · 2025 62%. Grants only. Government contracts and fees sit inside program revenue.
99% of CITY ISLAND OYSTER REEF INC’s revenue is contributions — more donation-reliant than the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 6 reported years ran a deficit.
