Figure 1-1: Cross-sectional views of the 100-year floodplain
Figure 1-1. The illustration above shows three views of a hypothetical 100-year floodplain along a channel and the effects of encroachment. The three views include a cross-sectional view with no development, a cross-sectional view with existing and new development (causing the flood elevation to rise), and a perspective view of the encroachment with increased chance of flooding in the flood fringe.
