The contour data that available from USGS is reportedly configured for you to set at any interval within GIS.

Many cities and counties have had their own topo and planimetric maps made. I have frequently seen contour levels down to one or two feet on the old ones.
In Minnesota, the maps are frequently done as ½, ¼, or 1/8 section. Those are old fashioned now, as the up to date cities are working with Lidar data.

Subject: 4 ft contour maps?
Does
anyone know of local topo maps with 4 ft contour intervals? Specifically, I'm looking for info on the area within the Cucamonga Peak
(CA) 7.5' Quad. I came across an uncited reference to such a map, but I can't find anything.
