Maui Businesses Face Heightened Flood Risk in South Kīhei and Other Areas

A recent "kona low" storm has left significant sediment accumulation in drainage systems, elevating the risk of flooding in several Maui areas, most notably South Kīhei. The Maui Emergency Management Agency (MEMA) has issued flood advisories, signaling the need for immediate business continuity planning and risk mitigation.

The Change

MEMA has identified South Kīhei as an area with a high risk of flooding, directly attributable to sediment buildup from a recent "kona low" storm. While cleanup efforts are underway to restore drainage capacity, the elevated flood risk remains. Other areas designated as having a moderate risk of flooding include ʻĪao, East Molokaʻi, Lahaina, and East Maui. These advisories are in effect due to the immediate aftermath of the storm and the ongoing, though incomplete, drainage restoration efforts, suggesting that any further significant rainfall could trigger flooding incidents.

Who's Affected

Small Business Operators

Operations in South Kīhei and the moderate-risk zones face direct threats from flooding. This could lead to temporary business closures, damage to inventory and equipment, and disruption to customer access. For businesses that rely on consistent foot traffic or deliveries (e.g., restaurants, retail shops, service providers), even minor flooding can result in significant revenue loss. Insurance claims may increase, potentially driving up future premiums. Staffing could also be impacted if employees are unable to reach their workplaces.

Real Estate Owners

Property owners and landlords in South Kīhei and the identified moderate-risk areas face potential property damage, including structural issues, water damage to interiors, and damage to landscaping. Accessibility to properties could be compromised for both tenants and maintenance personnel. This situation could lead to increased insurance premiums, a need for expedited repairs, and potentially temporary loss of rental income if properties become uninhabitable or inaccessible. Developers and property managers need to factor these risks into ongoing projects and tenant relations.

Tourism Operators

Hotels, vacation rental owners, and tour operators in affected zones are particularly vulnerable. Flooding can disrupt guest transportation, making it difficult for visitors to reach their accommodations or participate in planned activities. Properties themselves could sustain damage, impacting guest experiences and leading to cancellations or lost bookings. For vacation rental operators, managing guest expectations and ensuring safe access during flood advisories is critical. Any significant disruption could also impact the perception of Maui as a safe and reliable destination.

Second-Order Effects

Persistent flooding in key commercial and residential areas on Maui can lead to increased demand for flood insurance, potentially making it more expensive and difficult to obtain for businesses and homeowners. This, in turn, can deter new investment and development in high-risk zones. Furthermore, repeated disruptions to small businesses could lead to reduced local employment opportunities, impacting the broader Maui economy and potentially increasing reliance on tourism-dependent sectors. For tourism operators, the perceived risk of weather-related disruptions could influence booking decisions, especially if cancellations become frequent. Higher operational costs for businesses due to repeated flood-related damages and insurance could also trickle down to consumers in the form of higher prices.

What to Do

Given the immediate advisories and potential for recurrent flooding following storm events, businesses and property owners in South Kīhei and other moderate-risk areas should take proactive steps. The current situation requires vigilance and readiness rather than immediate, drastic action, thus warranting a "watch" status. Businesses should monitor official advisories and prepare for potential disruptions.

Specific Guidance:

  • Small Business Operators: Review and update your business continuity and emergency preparedness plans. Ensure key documents and inventory are stored in areas safe from potential flooding. Confirm your business insurance coverage details, particularly regarding flood damage and business interruption. Maintain communication channels with suppliers to understand potential supply chain impacts.
  • Real Estate Owners: Inspect properties for drainage issues and clear any debris that could exacerbate sediment buildup. Secure outdoor property and assess any immediate vulnerabilities. Communicate proactively with tenants about potential risks and MEMA advisories. Review property insurance policies.
  • Tourism Operators: Assess the accessibility of your accommodations and tour departure points. Prepare guest communication protocols for weather-related disruptions and cancellations. Ensure your operational plans account for potential transportation challenges. Coordinate with local authorities on any necessary advisories or evacuation procedures.
