Maui Businesses Face Increased Risk of Infrastructure Disruption and Operating Costs Following Record Rainfall

·6 min read·👀 Watch

Executive Summary

Maui County experienced its second wettest season in 30 years, with rainfall significantly exceeding average and causing widespread flooding in the 2025-2026 wet season. This recurrence of extreme weather necessitates a review of business continuity plans and insurance coverage for potential future disruptions and increased operational expenses.

  • Small Business Operators: Potential for physical damage, supply chain delays, and increased insurance premiums.
  • Real Estate Owners: Risk of property damage, increased maintenance costs, and potential for flood zone designation changes.
  • Tourism Operators: Disruption to visitor experiences, potential damage to properties, and increased operational costs for repairs and mitigation.
  • Agriculture & Food Producers: Risk of crop damage, soil erosion, and potential impact on livestock and water management systems.
  • Investors: Increased operational risk for businesses in vulnerable areas, potentially impacting asset valuations and investment portfolios.
  • Action: Watch insurance policy terms and local infrastructure resilience reports.

Watch & Prepare

Medium Priority

Past flood events, especially if recurrent, necessitate review of business continuity plans and insurance coverage, which is a planning activity.

Watch insurance policy terms and conditions for flood coverage, deductibles, and payout limitations. Monitor local county and state infrastructure resilience reports for updates on drainage improvements and flood mitigation projects triggered by increased weather events. Assess current business continuity plans against potential extended disruptions. If insurance coverage is found to be inadequate or business continuity plans lack sufficient detail for prolonged outages, begin the process of revising policies and plans within the next 90 days.

The Change

Maui County recorded its second wettest season in the last three decades during the 2025-2026 wet season, with rainfall totals ranging from 100% to 250% of the historical average across significant portions of the island. This period of extreme precipitation, driven by Kona Low storms and contributing to catastrophic flooding statewide, highlights a pattern of increased weather volatility.

Who's Affected

Small Business Operators Small businesses, including restaurants, retail shops, and service providers, face heightened risks of physical damage from flooding, sustained operational disruptions due to damaged infrastructure (roads, utilities), and increased insurance premiums as insurers reassess flood risk. Supply chain reliability could also be compromised by weather-related transportation delays.

Real Estate Owners Property owners, developers, and landlords must consider the increased potential for flood damage to commercial and residential properties. Repeated extreme rainfall events can stress existing drainage systems, increase maintenance costs for flood mitigation, and potentially lead to re-evaluation of flood zone designations by regulatory bodies, impacting future development and property values.

Tourism Operators Hospitals, hotels, vacation rentals, and tour companies are vulnerable to disruptions that directly impact visitor experience and safety. Damage to facilities, road closures affecting access, and potential cancellation of tours can lead to revenue loss. Furthermore, increased insurance costs and the expense of implementing enhanced flood protection measures will likely affect profit margins.

Agriculture & Food Producers Farmers and food producers are exposed to challenges such as crop loss due to waterlogged fields or flash floods, soil erosion, and potential contamination of water sources. Livestock may also be at risk. The increased frequency of heavy rains could necessitate significant investments in drainage infrastructure and revised planting strategies.

Investors For investors, this pattern of extreme weather suggests increased operational and physical risk for businesses located in flood-prone areas on Maui. This could translate to higher insurance costs, potential for business interruption losses, and ultimately impact the financial performance and valuation of companies in sectors heavily reliant on physical infrastructure or tourism.

Second-Order Effects

Increased frequency of extreme rainfall events and subsequent flooding can trigger a chain reaction within Hawaii's isolated economy. Elevated risks lead to higher insurance premiums and potentially increased demand for flood mitigation infrastructure, such as improved drainage and seawalls. These costs often fall back on property owners and businesses, increasing operating expenses. This can, in turn, put upward pressure on prices for goods and services. For tourism operators, increased costs and infrastructure challenges could affect pricing, potentially impacting visitor volume or shifting demand to less affected regions. For local small businesses, higher operating costs and potential supply chain disruptions can squeeze already thin margins, impacting their ability to expand or even maintain current operations.

What to Do

This period of heightened weather volatility requires a proactive approach. While no immediate hard deadline exists, businesses across Maui and the state should view these recent events as a strong signal to reassess their preparedness for extreme weather.

All Affected Roles: Monitor local government reports on infrastructure resilience projects and any updates from meteorological services regarding future weather patterns. Review insurance policies specifically for flood coverage, deductibles, and payout limitations. Assess business continuity plans to ensure they account for extended utility outages and transportation disruptions. Prioritize securing digital assets and developing remote work capabilities where feasible.

Investors: Pay close attention to companies reporting significant weather-related disruptions or increased insurance costs. Consider how recurring extreme weather events might factor into long-term risk assessments for portfolio companies operating in vulnerable regions.
