HB 1846 and HB 2205: What Hawai‘i’s Proposed Coastal Erosion Bills Mean for SMA Permits

HB 1846 and HB 2205: What Hawai‘i’s Proposed Coastal Erosion Bills Mean for SMA Permits

Erosion is not a new phenomenon along Hawai‘i’s shores, but a pair of bills currently moving through the state legislature could dramatically change how homeowners and developers respond to it. House Bills 1846 and 2205 would establish regional shoreline mitigation districts and allow limited, carefully conditioned shoreline hardening for private properties facing erosion. While the measures aim to give residents more tools to protect homes and condos, agencies worry the changes could put public beaches at risk. Here’s a look at what’s being debated and how it might affect your next Special Management Area (SMA) permit.

Why Lawmakers Want New Tools for Erosion

Residents from erosion‑plagued areas like Kahana on Maui and the North Shore of O‘ahu have spent years watching beaches shrink and sandbags fail. Under existing law, private shoreline hardening structures – seawalls, revetments and groins – are largely prohibited because they accelerate beach loss. State agencies already have emergency permitting authority, but it’s typically reserved for public infrastructure, not private homes.

HB 1846 would create regional shoreline mitigation districts and require properties within them to prepare coordinated coastal erosion and sediment management plans. The idea is to streamline review for erosion‑control projects that span multiple parcels instead of forcing owners to go through the permit process individually. HB 2205 would shift the current ban on private shoreline hardening to a “minimization” approach, allowing emergency permits for limited protective measures with conditions and a five‑year timeframe. Supporters say the bills provide relief for property owners who are losing land quickly, while opponents argue they could weaken hard‑won protections for beaches.

What This Means for SMA Permits

If enacted, these bills could influence the permitting landscape for coastal projects in several ways:

  • Regional coordination: Applicants might be required to participate in shoreline mitigation districts and file joint sediment management plans. This could simplify review for multi‑property projects but also adds another layer of documentation.
  • Emergency measures: Limited shoreline hardening, such as groins or temporary revetments, could receive emergency approval. SMA applications would still need to demonstrate compliance with Hawai‘i Revised Statutes §205A and county rules, but the timeline for protective work might shorten.
  • Stricter scrutiny on long‑term impacts: Even if private hardening is allowed, agencies will likely scrutinize plans for cumulative impacts on public access and beach ecology. Expect to supply detailed environmental narratives, drainage analyses and mitigation strategies.

The bills are currently deferred in committee but could resurface later this session. In the meantime, anyone planning a renovation or new build near the coast should prepare as if the current rules remain in effect. That means gathering extensive documentation – including architectural concepts, site plans, wastewater designs, maps and a lengthy narrative demonstrating compliance – and being ready for a multi‑agency review.

Preparing Your Coastal Project for the Future

Whether or not HB 1846 and HB 2205 become law, shoreline builders should take proactive steps to design for resilience and stay ahead of evolving regulations:

  1. Document everything: SMA applications require charts, maps and lengthy narratives. Commercial projects often need a 150‑plus‑page Environmental Assessment. Start compiling surveys, environmental data and preliminary design drawings early to avoid delays.
  2. Design for adaptation: Consider building setbacks, elevating structures and incorporating living shoreline features like dunes or vegetation. These measures reduce erosion risk and may make it easier to secure permits if limited hardening is allowed.
  3. Engage neighbors: Many coastal projects span multiple parcels. Coordinate with adjacent owners to develop regional mitigation plans, especially if the legislature ultimately requires them.
  4. Monitor legislative changes: Bills can move quickly in Hawai‘i’s short legislative session. Stay informed about amendments that could affect SMA requirements, emergency permitting or environmental review.
  5. Consult professionals: Architects, engineers and environmental scientists play critical roles in designing sustainable coastal projects. Shoreline Consulting doesn’t employ these professionals in‑house, but we maintain relationships with trusted experts who can join your project team as needed.

How Shoreline Consulting Hawai‘i Can Help

Navigating Hawai‘i’s SMA permitting process is complex even without legislative upheaval. Our team prepares the site plans, wastewater designs, environmental narratives and other documentation required for both minor and major permits. We coordinate with county planning departments, the state Office of Planning and Sustainable Development, the Department of Land and Natural Resources and cultural practitioners to help your application move smoothly through review. For commercial developments, we work with your engineers and architects to develop the 150‑plus‑page Environmental Assessment and ensure your design meets environmental and cultural standards. Because we monitor legislative proposals like HB 1846 and HB 2205, we can adjust your permit strategy quickly as rules evolve.

We do not have engineers or architects on staff, but we partner with experienced professionals to deliver architectural design and project management services. Our goal is to streamline approvals so you can focus on bringing your coastal project to life.

Looking Ahead

Sea level rise and intensified storm patterns will continue to challenge Hawai‘i’s shorelines. Whether lawmakers ultimately permit limited shoreline hardening or maintain the current ban, it’s clear that property owners and developers must adapt. Proactive planning, resilient design and early engagement with experts will remain critical. If you’re contemplating a remodel, new construction or erosion control project near the ocean, now is the time to start the SMA permitting process.
