*3.1. Overall RAF Structure*

The RAF is structured in two resilience dimensions, namely "Integration of NBS in the city" (Dimension I) and "Operation and services of NBS" (Dimension II). A set of 10 resilience objectives is proposed in the RAF. Dimension I considers four objectives and 12 criteria. Dimension II considers six objectives and 13 criteria. A set of 71 metrics is proposed, divided in 34 metrics for Dimension I and 37 metrics for Dimension II. In Dimension I, 24 data based and 10 procedure based metrics are proposed. In Dimension II, 25 data based, three procedure based, and nine model based metrics are considered. Figure 1 presents the RAF dimensions, objectives, and criteria.
