Nature-based adaptation strategies use natural systems—like dunes, wetlands, and eelgrass beds—to reduce coastal hazards while protecting coastal access and supporting biodiversity. In March 2026, the Coastal Commission adopted new guidance on Nature-Based Adaptation Strategies through a Coastal Act lens, building on the Commission’s 2024 Sea Level Rise Policy Guidance, which outlines a range of adaptation approaches, including nature-based solutions.

By working with natural coastal processes, these strategies help protect communities from hazards while supporting habitats, recreation, scenic resources, water quality, and carbon sequestration. Because they can adjust to changing conditions with fewer impacts on communities and natural resources, nature-based approaches are increasingly recognized as resilient responses to sea level rise. The new guidance explains the key principles the Commission will use to evaluate planning and permitting actions, along with available permitting pathways, Coastal Act review considerations, and important design and implementation guidance.
