Primary frontal dune definition

Primary frontal dune means a continuous or nearly continuous mound or ridge of sand with relatively steep seaward and landward slopes immediately landward and adjacent to the beach and subject to erosion and overtopping from high tides and waves during major coastal storms. The inland limit of the primary frontal dune occurs at the point where there is a distinct change from a relatively steep slope to a relatively mild slope.

The inland limit of the primary frontal dune occurs at the point where there is a distinct change from a relatively steep slope to a relatively mild slope.” Figure 1, taken from the May 6, 1988 Federal Register, illustrates the Primary Frontal Dune limit described above. 44 CFR subsection 60.3(e)(7) of the NFIP regulations requires that participating communities prohibit manmade alterations of sand dunes in VE Zones which would increase potential flood damage. Thus, expansion of a VE Zone via the PFD expands the dune areas protected by 60.3(e)(7).

FEMA also included a new section in 44 CFR Part 65, requiring that the storm-induced erosion cross-sectional area of 540 square feet serve as the basic criterion to be used in evaluating whether a primary frontal dune will act as an effective barrier during the 1-percent-annual- chance flood (see Event-Based Erosion report, Topic 37). The guidance in Appendix D for primary frontal dunes as it pertains to 44 CFR Parts 59, 60,and 65 described above, needs some clarification (which is addressed in some detail in Critical Topic
