Coastal cities face increasing natural disaster risks. Developing a green infrastructure network can reduce coastal vulnerability by connecting green spaces. Only a few researchers have examined practical guidelines for a green infrastructure network in coastal cities. Therefore, the purpose of this study is to build a green infrastructure network by integrating potential evacuation routes and green spaces in a coastal city. The Haeundae District in South Korea was chosen as the study site. We constructed a green infrastructure network using space syntax and GIS network analysis. The results of this study showed that first, we created an integrated green infrastructure network by building evacuation route networks and urban ecological networks. Second, we evaluated the evacuation function and flood risk. Finally, we proposed green infrastructure network planning for coastal disasters, including hub and corridor design. This study can contribute to establishing strategies to reduce vulnerability in coastal cities. This figure shows the green infrastructure network planning for coastal urban area in this study. [Display omitted] •The green infrastructure network in a coastal city can minimize natural disaster risks.•Disaster prevention parks can provide emergency shelters and ecological network hubs.•39.8% of the green infrastructure networks of Haeundae are high-potential evacuation routes.•Areas with a runoff index of 0.7 or higher are most vulnerable to coastal disasters.
