Twenty Castle High School students and their teacher, Sheila Cyboron, Vice-Principal Winona Enesa, School Administrative Services Assistant Cory DeJesus, and the maintenance staff, will participate in the Kawa Stream Adopt-A-Stream project, in collaboration with City and County of Honolulu.

            The goal is to establish a hands-on project to promote the long-term environmental stewardship of the City-owned portion of Kawa Stream.  This small educational test project not only promotes volunteer stream cleanups and pollution prevention education, but also demonstrates and implements erosion control practices using vegetative methods to help manage erosion and minimize herbicide use at the project site. 

            Iwalani Sato, the City’s coordinator, said, “We chose Kawa Stream because it’s on the Department of Health’s list of impaired waters in Hawaii and Castle High School is in the Kawa watershed.  Data show high levels of nutrients, turbidity, and suspended solids from the nearby cemetery, school, residential and commercial areas; and forest areas running into the stream.

Cooperating agencies are the State of Hawaii Department of Transportation Highways Division, State of Hawaii Department of Land and Natural Resources Division of Aquatic Resources, GeoTech Solutions, Hui Ku Maoli Ola, Kaneohe Neighborhood Board, Council Chair Barbara Marshall, and community-based groups in Kaneohe.

            Sato added, “The Adopt-A-Stream work days are ‘hands-on’ activities for everyday environmental heroes in our communities.  At a minimum, volunteers will remove trash from City-owned streams, pass out pollution prevention fact sheets, and stencil storm drains to remind citizens to ‘Dump No Waste, Protect our Waters … for Life’.”

The City’s Storm Water Quality Branch of the Department of Environmental Services, Division of Environmental Quality, will coordinate this Adopt-A-Stream project in collaboration with the City’s Department of Facility Maintenance, Department of Parks and Recreation Urban Forestry and the Honolulu Community Policing Team.  Anyone wishing to volunteer for the clean-ups may sign up online (
