This session explores the creation and implementation of the Ala Wai Watershed Special Improvement District (SID)—a pioneering approach to watershed-scale resilience that integrates cultural values, nature-based solutions, and diverse stakeholder governance. Developed through the Ala Wai Watershed Collaboration, a public-private partnership hui, the SID uses a nonprofit “Community Investment Vehicle” (CIVic) to coordinate green infrastructure, stormwater management, ecosystem restoration, and long-term financing strategies rooted in community priorities.
