Water Resources


Water law in Hawai‘i has historically been a multilayered issue involving both legal and cultural considerations. Knowledge of local laws and regulations related to real estate, land use, and zoning laws, while also taking into account Native Hawaiian traditions and the state’s rich history are key in advising this area of law.

Our firm has been at the forefront of the development of water rights law in Hawai‘i since before statehood. We help landowners, water system owners, and developers of surface and groundwater sources navigate the unique regulatory and political regime governing water rights in Hawai‘i.

What We Do
