Operating Guidance 9-13: Operating Guidance for Designation of Zone VE based on Wave Runup Height

Main Content
The purpose of this document is to provide additional guidance on Zone VE designations. For all new detailed coastal studies started in Fiscal Year 2011 or later, it is recommended that Zone VE only be mapped for areas subject to wave runup where the 2-percent wave runup elevation is at least 3 feet higher than the stillwater elevation. Where runup heights are less than 3 feet, the runup zone should be mapped as Zone AE. The existing depth criterion for wave runup zones should continue to be used to determine the inland limit of Zone VE if the runup height criterion for Zone VE is met.
