To improve water quality within Keokea Gulch, 7.4 acres of its riparian corridor have been protected. The project area was fenced off with feral ungulate fencing, and 3,000 native plants were planted. This alone reduces sediment loads by 9.7 tons, nitrogen loads by 75.5 pounds, and phosphate loads by 15.3 pounds annually. As an added benefit, R-1 wastewater is being used as irrigation.

The Keokea Gulch Riparian Corridor Rehabilitation Project is conducted through partnerships between the Maui County Office of Innovation and Sustainability, the Hawaii Department of Health Clean Water Branch, the Central Maui Soil and Water Conservation District, Haleakala Ranch, and Maui Environmental Consulting, LLC.
