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.

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.
