Relating To Adaptation Pathways Planning.
SB1598 would require the Hawaii Climate Change Mitigation and Adaptation Commission, working with state and county agencies, to develop and periodically update regional adaptation pathways plans to address sea level rise, coastal erosion, flooding, and groundwater inundation. The bill is aimed at vulnerable private and public development in shoreline areas, including residential, commercial, industrial, resort, and infrastructure uses, and it contemplates a sequence of adaptation measures over time, such as nature-based solutions, flood-proofing, elevation, armoring, zoning changes, and eventual relocation when triggers are met.
The bill also directs the commission to create a framework for identifying high-risk, high-value coastal areas, to prepare at least one regional plan for each county, and to complete the planning process framework by December 31, 2026, with county plans due by December 31, 2030. It requires culturally informed, community-engaged planning and alignment with state and county hazard mitigation, climate adaptation, general, and community plans. The measure includes a $2 million appropriation in each of fiscal years 2025-2026 and 2026-2027, to be expended by the Department of Land and Natural Resources for planning purposes.
SB1598 would add a new section to chapter 225P, Hawaii Revised Statutes, establishing a formal state planning mandate for sea level rise adaptation pathways. It would expand the commission’s responsibilities, require participation by specified state and county agencies, and direct county planning authorities and the Department of Land and Natural Resources to help implement the plans through existing shoreline setback, special management area, land-use, and state-land enforcement authorities. The bill would also add statutory definitions for adaptation measure, adaptation pathway, adaptation pathways plan, and adaptation trigger, and it would appropriate general funds to support the planning work.
Based on the bill text and the absence of recorded committee testimony or votes in the provided materials, the overall sentiment appears supportive and policy-driven, with the measure framed as a proactive response to well-documented climate risks. The findings emphasize protecting vulnerable communities, public trust resources, and taxpayer dollars, suggesting the bill is intended as a coordinated adaptation and resilience initiative rather than a controversial regulatory overhaul. No recorded opposition or amendment debate is available in the provided context.
The main potential points of contention are likely to be the scope of state and county coordination, the possibility of future relocation of private and public development, and the use of public funds for planning rather than immediate physical protection. The bill also raises land-use and property concerns by tying adaptation planning to zoning, shoreline setbacks, special management areas, and possible restrictions on armoring, which could draw concern from property owners, developers, and some local governments. At the same time, environmental, cultural, and coastal resource advocates would likely support the bill’s emphasis on managed retreat, community engagement, and protection of beaches and dunes.
