Jerome, What projection do you have set on your county map? Is is in state plane? If so your coordinates are in decimal degrees and the linear units for the state plane are US Survey Feet.  What you will need to do is open up a blank MXD and set the data frame projection to geographic, world, WGS 84.  Then display your xy data here and export the XY event layer to a shapefile.  Once you have done this you can then use the Project tool to project the shapefile you just made to the correct projection.  This should properly project your coordinates. The the problem with not having any attributes in the table maybe an illegal character in one of your field headings. Make sure your headings don't have special characters or spaces. The one that often catches you out is - as this does not throw an error you just get an empty table. regards Anthony ... View more

George: I was able to add 2010 FEMA BFEs and XS lines to the map. I will try some of the interpolation tools. Thanks again. - Jerome ... View more

Hi Jerome; Take a look at the Flood Planning Map ( http://solutions.arcgis.com/state-government/help/flood-planning/workflows/ ) if you have not already done so.  It can be used to identify which homes are at risk based on the flood elevation level.  Use the DEM to create flood impact areas for each flood level using the Create Flood Impact Area tool.  Then instead of using the Public Infrastructure layer or Facility Site Points you could use your address points (after they have been geocoded) as an input layer into the Create Flood Impact Plan tool. This tool will overlay the address points with the flood impact areas to identify which homes will be flood at each flood level.  Hope it helps. - Walt ... View more

Thank you very much. I will start downloading a DEM and try this technique! ... View more
