East Honolulu Watershed Management Plan

The EHWMP will be prepared in accordance with the State Water Code Chapter 174C, HRS and the City and County of Honolulu Ordinance Chapter 30, ROH. This is one of eight district water management plans that together will comprise the Oahu Water Management Plan.
