Windward Community College Low Impact Retrofit

HOK and Windward Community College (WCC) have partnered to install approximately 3,000 square feet of rain gardens and native vegetation in front of Hale 'Imiloa. This Low Impact Retrofit (LIR) is designed to capture storm water run-off from over 18,000 square feet of impervious surface from the roof, road and parking lots. The rain gardens trap and infiltrate the storm water run-off before it has a chance to carry pollutants into nearby Kea'ahala Stream and Kāne'ohe Bay.

Construction of the site began the week of March 10th, 2014 with excavation and formation of the rain garden basins and berms. Planting of native species took place during the first week of April. Students, Professors and community members helped install 2,000 native plants on the site.

Long term maintenance of the project will be conducted by HOK with considerable support from community volunteers and WCC's Sustainability Club. Volunteers will help to remove weeds and invasive species from the site as well as prune native vegetation and maintain the structural integrity of the downspouts and water collection basins while learning about the importance of capturing and infiltrating storm water to prevent pollution.
