What Ridge to Reefs Inc does
Mission

As stated on its FY2024 Form 990.
Programs
Supporting sustainable agriculture - developing and helping farmers implement low cost sustainable technology. Examples include efforts in puerto rico after hurricane maria in 2017 and continuing to the present as well as efforts to support and assist sustainable agriculture in the city of baltimore and palau.
$244,223 spent$234,802 earned by the program25% of program spendingBaltimore compost collective - engages baltimore teenagers with positive employment opportunities and training in workforce skills, food access programming, farming and community-scale composting. Youth gain guided, hands-on experience managing a small-scale composting operation. Compost they create is used to grow fresh produce. Healthy, locally produced food in the urban landscape addresses critical food deserts and builds resilient communities. Baltimore compost collective's operation is more than traditional methods applied in the urban landscape; they're innovating new and better ways to boost food production in community gardens and finding creative ways to repurpose additional sources of waste into healthy effective fertilizer.
$195,378 spent$187,841 earned by the program20% of program spendingRestoration coordination - coordinating and implementing watershed plans. This includes writing proposals, working on policy changes, coordination of interagency efforts, local communities and municipalities to ensure that implementation efforts are successful. This has included tracking down on-going sources of pollution and working with the appropriate agencies to see the issues are resolved. Places where we have been doing this work include the guanica watershed in sw puerto rico, vatia watershed in american samoa and places like the sassafras river, an agricultural watershed on the eastern shore of maryland and the st. Marys river in southern maryland where the watershed is experiencing tremendous growth due to a naval base realignment which if not well managed will threaten the health of the river.
$195,378 spent$187,841 earned by the program20% of program spendingHelping build more resilient communities - helping communities build more resilience including rainwater harvesting and solar energy. This includes designing and building several off-grid solar walk-in refrigerators in puerto rico as well as a mobile unit and designing and implementing solar water filtration and pumping projects for agriculture, resilience and health facilities.
$146,534 spent$140,881 earned by the program15% of program spendingWatershed planning - work with local communities and stakeholders to create watershed plans to help improve the protection and restoration of water and ecosystems within specific watersheds (the area draining to someplace people care about - a river, a bay, a coral reef). Communities help to define the goals and strategic projects and actions are defined as well as potential responsible parties, the expected costs and benefits. One of ridge to reefs goals is to perform at least one watershed planning project a year - examples have included the culebra watershed action plan (in draft), the la parguera green infrastructure plan and the cabo rojo watershed plan being initiated in 2013 and the vatia watershed plan completed in 2019. Our emphasis has been to support the implementation of watershed plans not just their creation - we support the creation of these plans by assisting with funding proposals, policy and behavior change, implementation of restoration practices and helping build the skill set of local groups and municipalities for continued implementation and protection efforts.
$97,689 spent$93,921 earned by the program10% of program spendingGreen infrastructure - recreates natural systems to perform ecosystem functions within the urban environment - this includes bioretention practices, bio-filters, urban tree planting to reduce stormwater runoff and practices that include urban agriculture and green roofs. The practices help perform phytoremediation, restore urban soils and ecosystem function where it is most needed. Ridge to reefs, with its partners, implemented 8 green infrastructure projects in the last two years including bioretention, rain gardens, woodchip bioreactors, p-filters, rainwater harvesting and a sand biofilter. Over fiftteen thousand plants, mostly native, were planted in these projects to restore ecosystem function and reduce pollution and help cleanse contaminated stormwater runoff. We worked with local communities, landscape architects, engineers and developers to integrate these practices into their sites. Locations for this work included la parguera and tamarindo beach in culebra both in puerto rico, west maui in hawaii and the eastern shore of maryland and the st. Mary's river watershed in southern maryland.

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 2021 to 2022, from $55k to $292k (+435%).
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: 2020 7% · 2024 15%. Grants only. Government contracts and fees sit inside program revenue.
17% of RIDGE TO REEFS INC’s revenue is contributions — more earned-revenue than three-quarters of its peers (97% for the typical peer).

Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 4 funders to 6 funders, grant income fell $297k → $268k.
8 of 23 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 13% 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 RIDGE TO REEFS 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.
How concentrated its funding is
RIDGE TO REEFS INC leans on a few funders — its largest provides 56% of grant income and the top three 69%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
83% 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 RIDGE TO REEFS INC.
Largest funder’s share by year: 2017 51% · 2018 88% · 2019 93% · 2020 76% · 2021 71% · 2022 27% · 2023 42% — diversifying over time.
“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
22% of RIDGE TO REEFS INC's funders are still giving 3 years after their first grant; 39% 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
RIDGE TO REEFS INC draws 90% of its grant income from funders outside Maryland, across 8 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $265k arriving through sponsors registered in 6 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.
