Our Process
A Resilience Roadmap
By the end of 2026, the One Water Honolulu Plan will support implementation of the City and County of Honolulu’s Climate Ready O’ahu strategy, to prepare and safeguard people, ʻāina, and infrastructure, by providing a holistic water management plan and a 30-year Capital Improvement Program of multi-benefit projects to build resilience in our island’s infrastructure and natural systems.
The One Water Plan is a collaborative roadmap that focuses on how to implement the resilience strategy, recognizing that most climate impacts involve water—too much or too little of it.
Dive into O’ahu’s Water story
Several current planning efforts can be leveraged to support One Water Solutions across O’ahu.
There is a wide range of potential stakeholders to consider when building resilience across our infrastructure and for our communities.
Guided by a Collaboration Framework
A key component of One Water Honolulu is the Collaboration Framework, which provides a structured approach for action-oriented solutions and joint decision-making.
It recognizes that climate change impacts can only be mitigated by collaboratively working together within City and state agencies, large landowners, developers, organizations, consultants, and the community.
Collaboration is so essential to achieving climate resilience that it was institutionalized in City Ordinance 20-47, which created the One Water Panel of eight City Departments that will extend progress across future administrations and ensure continuity in purpose and long-term results.
Developing One Water Projects
Through the Collaboration Framework, the One Water Panel and its partners will coordinate infrastructure development, including identifying priority projects and developing project scopes and budgets.
The panel will also maintain a multi-year infrastructure investment strategy for the identified projects through the City and County’s annual Capital Improvement Program budget, implement associated policies and regulations, and pursue partnerships between agencies, developers, and the community.
