With the NG911 GIS data model coming out, I am testing out a tool that would take your 911 street centerline layer and changes it into the NENA data model. With this tool you can match the NENA field with the corresponding field in your data. If you don’t have a corresponding field, the tool will still create the NENA field, but will leave it empty.
If anyone would like to try it out, you can get it here: https://www.dropbox.com/s/6ddywkap4dxvjis/NENA_Street_Tool.zip?dl=0
This download includes a README file which explains what you need to do.
Please remember this is still in testing, so if you have any issues please let me know. I created this tool in ArcGIS 10.3.1. I don’t know if this will work in lower versions.
