Bill Summary · SB 1559

Legislative bill overview

SB 1559 establishes or modifies Hawaii's dune restoration programs and policies to protect and rehabilitate coastal sand dunes. The bill has passed initial legislative hurdles and was referred to three House committees (Higher Education, Water and Land, and Finance) for further review before being carried over to the 2026 session.

Why is this important

Coastal dunes provide critical natural buffers against erosion, storm surge, and sea-level rise—increasingly vital as Hawaii faces climate-related threats. Dune restoration also protects ecosystems, recreation areas, and infrastructure while potentially reducing long-term coastal management costs. Without proactive dune protection, Hawaii communities face accelerated property loss and environmental degradation.

Potential points of contention

  • Funding mechanisms: The Finance Committee referral suggests questions about how dune restoration will be funded—through general appropriations, user fees, or public-private partnerships
  • Land access and private property: Dune restoration may require access to or restrictions on private coastal properties, raising concerns about property rights and compensation
  • Competing priorities: Budget constraints may pit dune restoration against other environmental or infrastructure projects, especially given the carry-over to 2026
