topo map of NJ
(OP)
I just relocated to NJ, work with ... small land development firm. They use USGS map to determine storm drainage areas.
I am trying to find topo map of NJ with contours at least every 5'.
Does anybody knows website where I can download such map?
Thank you!

New Jersey - All counties are covered by LiDAR data with a vertical accuracy of 13-18.5 cm which supports 1-2 foot contours. Most of this data is available on the USGS National Elevation Dataset (NED) or CLICK websites.

Lidar is a fairly good alternative; but, it also has its issues. One would need a processor to establish a bare ground model and then have the correct tools (ARCGIS or ?) to use it for hydrology.
You can always check with the Flood Control District or Transportation Department to see if they have more detailed mapping available at a small cost.
