Floodway Profile

Screenshot of the Surcharge section with 'Default' highlighted.Although more than one profile may be displayed in the 'Profile' column, if the user assigns the "1%-annual-chance" frequency to the first profile and the "Floodway" to one of the remaining profiles, cHECk-RAS will perform NT, XS, Structure, and Floodway Checks. Note that cHECk-RAS can automatically determine if a profile contains encroachment options. Also the user cannot incorrectly specify a profile as floodway if no encroachment exists also the user cannot specify a profile as a particular frequency flood if encroachment options exist in the run.

Selecting Surcharge Values

Screenshot of the Update Default Surcharge window. Enter the Default Surcharge value in the field provided. Disclaimer in the popup window states: 'Disclaimers: It is the responsibility of the user to ensure that the appropriate surcharge value is used for a given project, based on National Flood Insurance Program, state and local requirements.'As stated earlier, a default surcharge value of 1.0 foot will be used to perform the Floodway Check unless a different surcharge value is specified by the user. To change this value:

  1. Select the desired state name/surcharge value from the 'Surcharge' list prior to running the program.
  2. Or, change the default surcharge value by double clicking on the 'Default' row in the Surcharge section and entering the desired default surcharge value
