One Water Honolulu

In December 2020, the Mayor of Honolulu signed Ordinance 20-47, which implemented a One Water policy for the city and enacted an integrated resource planning and implementation approach to managing finite freshwater, wastewater, and stormwater resources. This approach sought to ensure available for long-term resilience and reliability of available water resources to meeting both community and ecosystem needs in the present and future.

The City of Honololu partnered with Carollo to serve as the technical advisor to One World One Water (OWOW) to engage and establish a One Water Panel composed of various departments within the City and County of Honolulu. Carollo developed a roadmap which lays out a foundation to guide the One Water Panel in their development of a One Water Collaboration Framework, and proceeded to lead the Panel toward development of a shared One Water vision, goals, and resilience strategies through a series of monthly workshops. Carollo continued to support the panel through 2021, guiding its formation and facilitating inter-departmental collaboration to identify and develop One Water project opportunities to promote multi-benefit projects success stories.  

The Panel continues toward its target outcomes, which include establishing a working agreement for interagency collaboration, supporting near-term opportunities, identifying key strategies on which the panel can focus, establishing the collaboration framework and integration with existing plans, and developing a space to cultivate relationships and foster partnerships.
