Agricultural Resource Management

Dear Water Users and Lessees,

We recognize that the COVID-19 pandemic has led to anxiety and confusion around the world and in our islands. Our hearts and thoughts go out to each one of you during this time of uncertainty.

The Agricultural Resource Management Division will remain open, with limited staff per the Governor’s message to do our part to flatten the curve. However, our Irrigation workers will continue operating the irrigation systems, for as long as we have healthy workers and safe conditions.

These precautionary measures are being taken to help limit the spread of the virus and to support the people of our state during this time of crisis. If you need further assistance, please do not hesitate to call us or leave a message at (808) 973-9473 and someone will assist you as soon as they are able to.? Thank you for your patience and understanding.


The Agricultural Resource Management Division administers the development and management of key agricultural resources.

Land and water are two ingredients essential to sustaining agricultural operations. In recognition of Hawaii’s limited land and water resources, the State Department of Agriculture is charged with preserving these important resources to ensure the viability of Hawaii’s diversified agricultural industry.

Through its Agricultural Resource Management Division, the department operates the State’s Agricultural Park Program. The major objective of this program is to assist people who are interested in leasing land for farming ventures by providing irrigation water, reasonably priced farmland with infrastructure and facilities to encourage competition within the industry.

The program is composed of three separate sub-programs:



  • East Maui Water Systems Improvement Project
    In 2018, the Hawai?i State Legislature appropriated funding for capital improvement project (CIP) funding for plans, design, and construction for irrigation and water delivery systems in East Maui to support agricultural purposes.? The legislative intent was to primarily support the small farmers in East Maui in furtherance of the State’s goals of food security and self-sufficiency.In May 2019, the Hawai?i Department of Agriculture and its Project Team introduced the East Maui Water Systems Improvement Project (Project) to the community, and specifically the East Maui community.? Phase 1 of the Project entailed the Project Team meeting with key stakeholders to gather relevant input to identify and assess potential projects for HDOA’s consideration.? During this phase, we also conducted site visits of potential projects and held two public meetings to update the community and gather additional input.Based upon the community engagement, the Project Team conducted site assessments for the potential projects, taking into consideration the feasibility of completing each proposed project based upon a matrix of key factors.? The Project Team prepared a prioritization matrix to assist HDOA in determining which proposed projects should proceed to the design phase.? We are currently in the design and regulatory process phase to ensure timely use of the CIP funds.This process is detailed in the East Maui Water Systems Improvement, Proposed Project Summary Report dated December 16, 2019: you have any questions, please contact Janice Fujimoto with HDOA at 808-973-9473 or via email at [email protected]. or Dawn Chang with Kuiwalu at [email protected].
