Certified Floodplain Manager (CFM) Practice Exam 2026 – Complete Preparation Guide

Wet floodproofing is a method of floodproofing that involves using water-resistant materials below the Base Flood Elevation (BFE) of a building. Strengthening building foundations (option A) is related to dry floodproofing, which involves sealing the building to prevent water entry. Elevating properties above ground level (option C) is part of another floodproofing method called wet floodproofing with relocation, which involves moving the building to a higher location. Preventing water entry into buildings (option D) is also a component of dry floodproofing. Option B is the most accurate because it specifically mentions using water-resistant materials, which is the main principle behind wet floodproofing.
