Chapter 5
Flood Design Criteria
Publication: Climate-Resilient Infrastructure: Adaptive Design and Risk Management (MOP 140)
Abstract
This chapter depicts coastal flooding components and summarizes special flood hazard areas. Prior to calculating flood loading within coastal locations, the design flood event’s anticipated depth of floodwater and wave action must be determined. The design flood elevation (DFE) is used to obtain flooding depths and calculate certain flood loads based on local topography. The chapter discusses the DFE standards. DFE criteria are often developed during conceptual or predesign phases for a project and are subject to cost-benefit and sensitivity testing. The DFE should, at a minimum, conform to stakeholder requirements, industry standards, model codes, and other regulatory requirements. The DFEs are determined by applying freeboard to the base flood elevation. Per FEMA and ASCE, freeboard is a factor of safety, expressed in ft above a flood level.
