How to read the Tax Assessment Page and Fema Flood zone

[John Moon]

Hey team,

I have a question on how to read the data from the assessment website. 

For http://tax1.co.monmouth.nj.us/cgi-bin/m4.cgi?distr...

What does these mean?

Sale Information - Book, NU# Page

Additional Information - Addl Lots, Land Desc, Bldg Desc, Class4Cd

Also how do you know if the house is in the flood zone? I don't know how the FEMA flood map is supposed to be read..
