Report on meeting of the Technical Mapping Advisory Council to FEMA

from September 25-26 — USGS Headquarters, Reston, VA
Submitted by Wendy Lathrop, PLS, CFM


The focus of this meeting was to bring the 2018 Annual Report to a point where the content was complete and approved by all Council members, with the exception of technical edits. Discussions were detailed, and at times heated, as changing wording could at time alter the focus of the material, and the differing perspectives had to be aligned for a consensus. What seems like inconsequential changes do in fact alter meanings as well, and being particular about words meant reminding some of our members of distinctions between terms. For instance, there is a slight but significant difference between the phrases "1% annual chance floodplain" and "Special Flood Hazard Area." The first is defined by a particular annual probability of inundation, while the second is an area subject to a 1% or greater chance of flooding in any given year. more
