Overview of the Acquisition Process
The Hawai‘i Agribusiness Development Corporation (ADC) is advancing towards acquiring the Wahiawa Dam and spillway, a critical infrastructure project with a repair cost exceeding $60 million. The ADC board recently approved a $4.9 million purchase of the remaining land necessary for the acquisition from Sustainable Hawai‘i LLC, owned by attorney Howard Greene, and Dole Food Co. This acquisition is part of a broader initiative to take over an irrigation system that extends from Wahiawa to the North Shore, with a completion deadline set for June 30, 2026.
Safety and Environmental Concerns
The Wahiawa Dam, over 120 years old, has been flagged for its hazardous condition, holding the second-lowest federal safety rating and the highest hazard rating. Recent heavy rains from the Kona storms raised water levels dangerously close to the dam's brim, prompting evacuations of thousands of residents downstream. Dole Food Co. has faced criticism for neglecting safety standards, with state officials noting that the company has not adequately addressed issues related to the dam's spillway and embankment stability.
Environmental assessments have revealed contamination concerns, including lead and fuel residues on the land being acquired. However, ADC officials have indicated that these findings will not halt the acquisition process.
Financial Implications and Future Prospects
The financial burden of repairs has escalated, with initial estimates of $21 million rising to $43 million as requested by Governor Josh Green. Dole estimates that restoring the irrigation system could cost around $35 million, with an annual maintenance bill of $2.5 million. Despite these costs, Dole's consultants have suggested that a restored system could become self-sustaining, potentially generating revenue through irrigation services and hydropower generation.
The irrigation system currently serves approximately 9,500 acres and has the potential to expand to 17,000 acres if restored. This could yield an annual income of about $1 million from irrigation services.
Official Statements & Responses
ADC board chair Jayson Watts emphasized the responsibility that will fall on the agency post-acquisition, stating, “Come July 1, this is going to be your responsibility, and the life and property.” Meanwhile, ADC senior executive assistant Mark Takemoto noted the importance of moving forward with the acquisition despite environmental concerns, asserting, “It’s of benefit to the state to acquire.”
Criticism & Opposition
Some board members expressed skepticism regarding Dole's commitment to addressing the dam's safety issues. Wes Yoon, the only board member to vote against the acquisition, criticized Dole for not adhering to prior remediation plans. Additionally, concerns have been raised about the potential financial implications of maintaining such an aging infrastructure.
What's Next
The ADC is expected to finalize negotiations with Dole and Sustainable Hawai‘i LLC in the coming weeks, with a request for final approval of the terms anticipated in May 2026. The state aims to ensure the dam's safety and restore the associated irrigation system to mitigate risks and enhance agricultural productivity in the region.
