Notable achievements

Permanent protection of Kānewai Spring

Through partnership with Trust for Public Land and community action, Kānewai Spring and its surrounding estuary were conveyed to community stewardship, securing long-term protection for the site and enabling ongoing restoration and public access.

Hydrology repair funding and engineering partnership

MFHC worked with State representatives and the DLNR Engineering Branch to secure and direct more than $1.5 million toward reconnection and repair work at Kalauhaʻihaʻi, and collaborated on trenchless drilling and other engineering solutions during 2023–2024 to restore mauka-to-makai freshwater flow.

Expanded financial and operational capacity (2024)

Recent fiscal filings show materially increased contributed support and net assets, enabling MFHC to raise capital for stewardship (including approximately $300,000 for site work) and to serve roughly 800 program participants annually through volunteer restoration, school programs, and cultural workshops.
