Hui o Ko`olaupoko proactively implements projects in the Ko`olaupoko moku (Makapu`u to Kualoa) that address land-based pollution/watershed health as they impact water quality and the receiving waters of Waimanalo, Kailua and Kane`ohe Bay.
Projects are prioritized using a variety of tools including the Watershed Restoration Action Strategy (Kailua Bay Advisory Council, June 2007) and Ko'olaupoko Urban Sub-basin Action Plan and other scientific documents. In concert with active, on-the-ground restoration, HOK conducts monitoring for baseline water quality conditions, project effectiveness and assist with volunteer data collection.
Hui o Ko`olaupoko projects include but are not limited to Watershed Restoration & Stormwater Management
Due to human interaction with the island environment, the native ecosystem has been significantly altered over the course of thousands of years. For example, invasive plants and animals dominate our forests; the path of streams has been altered through dams, diversions, channelization and/or flood mitigation projects; stream banks are eroding; impacts from livestock grazing and agricultural practices; impairment of aquatic specie migration, etc. All of these activities cumulatively impact water quality along all reaches of the stream.
Most of Hui o Ko`olaupoko projects focus on riparian (stream corridor) restoration. HOK works with various landowners and agencies to restore the land back to its native ecosystem.
Watershed restoration activities include:
- Fencing to keep out nuisance animals
- Land clearing and weeding to remove invasive plant species
- Replanting with native vegetation
- Erosion control practices
HOK works with community volunteers who dedicate their time to restore and maintain some very beautiful and special restoration project sites.

Stormwater is the result of precipitation in which the water that does not infiltrate into the ground becomes surface water runoff that enters into streams and the ocean, in many cases, via the storm sewer system. However, when stormwater flows along an impervious surface (a hard, non-absorbing surface such as asphalt or concrete) it picks up a multitude of pollutants along the way. Pollutants include oil and grease, heavy metals, sediments, trash/debris, fertilizers, pesticides, pet waste, etc. On Oahu, stormwater runoff is usually routed off the land and into the nearest storm drain or stream and then dumped, untreated, directly into the ocean.
In a natural system, stormwater either infiltrates into the ground or is absorbed by vegetation. Hui o Ko`olaupoko aims to treat our precious rain water as a resource rather than a waste. HOK implements projects that mimic natural systems - capturing, storing and infiltrating stormwater, which recharges our ground water aquifer and prevent polluted runoff from entering our streams and ocean.
HOK works with private landowners to design and implement projects on their properties that help to capture and infiltrate stormwater using 'Low-Impact Development' technologies and native landscaping.

Hui o Ko`olaupoko offers monthly opportunities for volunteering and education such as stream restoration, native garden maintenance, water quality monitoring and public presentations. Participants at every event are educated on the health of the watershed, sources of pollutants and opportunities to take individual action for watershed health and ocean protection.
