Community-led projects aim to improve the health of the Ala Wai watershed – Hawaii Sea Grant Community-led projects aim to improve the health of the Ala Wai watershed Honolulu, Hawai‘i—The University of Hawai‘i Sea Grant College Program (Hawai‘i Sea Grant) has awarded six grants for Green Stormwater Infrastructure (GSI) projects in the Ala Wai watershed.
These projects are part of the Ola Waikīkī project, a transformative effort aimed at improving the health of the Ala Wai Canal by improving water quality, enhancing ecosystem resilience, and engaging communities in sustainable solutions.
Green stormwater infrastructure (GSI) is a collection of design strategies that mimic nature to manage and treat stormwater and encourages water to infiltrate into the ground, minimizing and slowing the flow of runoff and removing contaminants. It encompasses a variety of nature-based solutions designed to restore natural hydrological processes.
They range from native rain gardens and tree planting to floating treatment wetlands, all of which help to filter pollutants, slow runoff, and replenish groundwater. Dr. Darren T.
Lerner, Hawai‘i Sea Grant director, noted “The pollution of the Ala Wai canal and the watersheds that feed into it have long been an issue rising to more prominence with the increased frequency of storms, and highlighting the urgent need to develop immediate solutions and strategies for the sustainable long-term management of the watershed.
The Ola Waikīkī effort and associated community-led projects incorporate community input and support real-world pilot projects that residents can see and experience. These projects provide an opportunity to demonstrate small-scale application of GSI that can eventually be scaled up into regional projects that support meaningful and impactful benefits to the environment and community.
” Ola Waikīkī is funded by Congressionally Directed Spending led by U.S. Senator Brian Schatz. The project team includes Hawai‘i Sea Grant’s principal investigator Dr. Darren T. Lerner, and co-investigators Melanie Lander, community planning and design extension agent, and Dolan Eversole, coastal processes specialist.
Community-Driven Projects Making an Impact An expert panel convened by Hawai‘i Sea Grant identified six community-led projects to demonstrate the power of local action in urban environmental restoration and stormwater management.
The six projects awarded include: Aliʻiolani Elementary School Cafeteria Rain Garden (Hawai‘i Green Growth UN Local2030 Hub) – This project will install a rain garden designed to capture approximately 80,000 gallons of rainwater annually, serving as an educational tool for students and the broader Pālolo community.
Increasing Urban Tree Canopy at Jarrett Middle School (The Outdoor Circle) – Shade trees will be planted to mitigate flooding impacts in Pālolo Valley, reduce stormwater runoff, and create an on-campus arboretum to educate students about native tree species and environmental sustainability.
M&M (Maintaining & Monitoring) the Kaimukī Rain Garden (Trees for Honolulu’s Future) – Enhancing an existing rain garden on 11th Avenue, this project will explore the effectiveness of various groundcover plants and engage volunteers in hands-on sustainability practices.
Pālolo Hongwanji Sustainable Community Hub (Trees for Honolulu’s Future) – A suite of green stormwater infrastructure solutions, including rain barrels and rain gardens, will be implemented to intercept and treat stormwater before it reaches Pālolo Stream and the Ala Wai Canal.
Pu‘uhonua: Distributed, Scalable Phytoremediation (Grow Good Hawai‘i & Iolani School) – Floating wetlands featuring native Hawaiian plants will be deployed in the Ala Wai Canal to improve water quality, enhance biodiversity, and explore cost-effective ecological restoration methods.
Restoring Roots at Puʻu o Kaimukī Mini Park (808 Cleanups) – Erosion control and native biodiversity restoration will be prioritized to reduce runoff, promote traditional ecological knowledge, and engage volunteers in creating a more resilient urban ecosystem.
By leveraging community knowledge, hands-on participation, and strong partnerships, these initiatives are a first step toward long-term water quality improvement and urban resilience in Honolulu. For more information on these projects or to get involved, please visit: https://seagrant. soest.

The full ASPECT NOFO (DE-FOA-0003647) posted September 4, 2026, eleven days later than the Notice of Intent predicted. The real document splits $58 million across two topic areas with anticipated award counts of 0-7 and 0-3, a cost share that jumps from 20 percent to 50 percent mid-project, a mandatory five-page concept paper due October 9, and a university eligibility restriction that decides team structure before anyone writes a word.
Read articleThe Humana Foundation's first 2026 slate funded 13 nonprofits and five university research teams around senior and veteran emotional health, with awards from $150,000 to $3 million concentrated in Texas, Florida, and Kentucky. A second health equity slate is planned for fall 2026. Here is what the portfolio structure reveals about how this funder decides, and how aging-services and behavioral health organizations should position.
