Mā‘ili‘ili Watershed Management Plan ( 2014 )

Townscape worked with the State Department of Health Clean Water Branch to develop the Māʻiliʻili Watershed Management Plan. The goal was to formulate an environmentally holistic, community-based, and economically viable watershed management plan that addresses land-based non-point source pollution and identifies solutions to restore and protect water quality and aquatic resources in the Māʻiliʻili Watershed. The planning process followed guidelines specified by the U.S. Environmental Protection Agency and included stakeholder consultation, watershed and pollutant load modeling, GIS analysis, and extensive research. Solutions included specific priority projects for implementation. Funding for implementation is available through Clean Water Act section 319(h), with matching funds available from a settlement agreement between the City and State.
