Stormwater management at Marine Corps Base Hawaii is a critical part of the base's environmental stewardship. The MCBH has implemented a variety of methods to manage stormwater runoff, including the construction of infiltration basins, swales, vegetative swales, and culverts. These features capture, filter, and slow the runoff, preventing pollutants from entering the native water of Hawaii and helping to reduce flooding. MCBH has a comprehensive Stormwater Management Plan (SWMP) in place that outlines best management practices and strategies to reduce the impacts of stormwater runoff for construction, industrial, and commercial locations.
