Climate vulnerability assessment finds higher flood risk at Santa Barbara Airport; runway closures could become more frequent
Summary
Consultant ESA presented a climate vulnerability assessment showing precipitation-driven runoff and creek flooding currently dominate airport flood risk; with projected climate change and sea-level rise, events that close the airport are expected to become more frequent and adaptation options will be required.
A consultant-led climate vulnerability assessment (part of a three‑phase adaptation plan) presented modeling showing that increased precipitation from climate change, combined with sea-level rise, will raise the likelihood of flooding events at Santa Barbara Airport and increase both frequency and economic impacts of runway and apron flooding.
Key findings presented by ESA: - Sea-level scenarios (2024 OPC guidance, intermediate-high risk): near-term ~0.8 ft (around 2048), mid-term ~2.5 ft (circa 2076) and long-term ~6.6 ft (circa 2130). - Precipitation changes: events that historically occurred once every 5…
