Hawaiʻi County Launches Waikōloa Evacuation Traffic Study with Meeting

County officials disclosed the new study at the end of December, saying the effort is funded through a U.S. Department of Housing and Urban Development Community Development Block Grant for hazard mitigation and will be carried out by KLD Associates for Hawaiʻi County Civil Defense. Officials plan to use the work to identify congestion points, test traffic flows under evacuation scenarios, and propose actionable changes to roads, signage, and planning that reflect local needs.

The project will analyze current evacuation corridors, including primary access via Waikōloa Road and the designated emergency route on Hulu Street, and will incorporate projections of population growth to estimate future demand on those routes. Study results are intended to produce recommendations that prioritize safe, equitable evacuations and address the specific needs of vulnerable populations.

The County cited lessons from the 2021 Mana Road fire evacuation as a key motivation for the study. That event highlighted how rapidly evolving emergencies can strain limited roadway options and challenge residents with mobility or transportation limitations. County leaders say they want the study to capture neighborhood-level knowledge so recommendations reflect on-the-ground realities rather than theoretical models alone.

A public meeting will kick off the engagement phase on Jan. 9, 5 to 7 p.m., at the Waikōloa Village Association Golf Banquet Room, 68-1792 Melia St. Residents are invited to attend to share local observations about traffic patterns, pinch points, and community needs. The County has emphasized that public input will shape models and final recommendations, especially measures intended to assist older adults, people with limited mobility, and households without ready access to private vehicles.

For Waikōloa Village and surrounding communities, the study could lead to tangible changes over time: revised evacuation routing, targeted infrastructure upgrades, clearer signage, and coordination with emergency services to reduce evacuation times and confusion. Because the project is funded as hazard mitigation, recommended changes may be eligible for federal support, increasing the chance of implementation.

The study also reflects broader concerns about emergency preparedness on the Big Island as development and demographic shifts intersect with wildfire and other hazards. Officials say next steps after the Jan. 9 meeting will include data collection, traffic modeling, draft recommendations, and further public outreach as the County refines proposals for safer, more resilient evacuation systems.
