Al, the data used to generate the contour lines comes from the 1/3 arc second National Elevation Dataset (NED13) which is a standard used on most topo maps. The choice of interval doesn't mean it will be more "accurate", just that there are more lines. For my 2012 map I used the 1/9 arc second National Elevation Dataset (NED19), which is much higher resolution LIDAR data. But I found that it made very messy contour lines that cluttered the topo map, so I have gone back to NED13 on this map.
Guy, here's a map of the same area at the same resolution (6 feet/pixel) showing tax parcels. These come from the state's parcel database. I have created labels that show BLOCK/LOT. Don't know if this will help you, but it was pretty easy to make using data I already had. It is a kmz file containing TIFF images, which seem to be cleaner than the JPEG files I used for the topo.
