Dense topographic data for a lot.

I've got Home Designer Architectural 2014 and a desire to buil a house on a steep hillside. I need topographic data for this.

In this program, I can import data about the topography of a lot in the form of a .gpx file. Google Earth can export a map of pins (but not a shape) to a data file that can be converted to .gpx, but placing those pins manually at a useful density would take forever and I'm not sure that Earth has sufficient elevation resolution.
So where can I get this data? Are there USGS maps with high enough resolution? An app that can plot X, Y, and Z coordinates while I walk around the lot?
Ideally I'd like everything to be accurate to within a foot, but I'll take the best I can get.
