Kalihi Stream flows through a rural/urban, low income, high immigrant, residential, small business community. The stream is heavily impacted by runoff, green waste, residential and small business debris, riparian gardeners, and other pollutants. These land use practices affect both Kalihi and Kamanaiki streams and ultimately add to the problems of siltation, turbidity and suspended solids in Keehi Lagoon.
Objectives/Goals: The project intends to improve the waters of Keehi Lagoon through the restoration of a section of Kalihi Stream and the establishment of a nonpoint source pollution education and community action program. The contractor is developing a monitoring plan to tract the progress of the project’s restoration and outreach efforts and is working with local teachers in developing a curriculum that includes information on nonpoint source pollution and will use the restoration site as an outdoor classroom. The Polluted Runoff Control Program recently participated with PTP and the City and County of Honolulu in an island-wide watershed model contest for high school and intermediate school students.
