For Class III dams

A fillable EAP form is available for developing an EAP or the EAP can be developed following the ICODS guidelines above.
(Download an EAP fillable form template 144KB MS Word File)
(Example of a completed fillable EAP as 720KB PDF)

For Class II dams

The ICODS guidelines may be used to develop the EAP. Or, it is possible that the fillable EAP form could be used to develop an EAP for a Class II dam.  However, you must discuss the applicability of the fillable EPA with Dam Safety staff prior to developing the EAP.

   FEMA flood maps are available to the public, and you can print your own "FIRMette" using this service. A "FIRMette" is a FREE 8.5" X 11" flood insurance rate map of your respective geographic area. You can also purchase entire FIRM panels and/or copies of Flood Insurance Studies (FIS). Persons requiring assistance may call MSC Customer Service at 1-877-336-2627.
GIS Flood Map Data

As more communities are remapped using Geographic Information Systems (GIS), FEMA will make GIS floodplain maps available through the FEMA Flood Map Store mentioned above. Until this map modernization effort is closer to completion, the GIS compatible floodplain datasets should be obtained from the FEMA Flood Map Store. Once this remapping effort is closer to completion our office will begin to incorporate the ability to download GIS compatible files from this site. For the present, our office can photocopy sections of FEMA floodplain maps & make them available for pick-up or by surface mail.
