PDF. file import?

[lgswe]

My client sent me a pdf. file of a large industrial lot that is showing many new building additions and roadways. The client wants me to show where the new office building I'm designing will be placed on the lot. I also have a dwg. file of the survey of the lot showing only the elevation data and other items pretaining to the land survey (no buildings or roadways). My thought was to copy the pdf file into it's own CA file. I then would trace over roadways and other pertinent info I need from the pdf. file and then copy the cad lines into the industrial lot dwg. file which I downloaded into another CA file. To me this seemed like the best way for me to go about getting info off the pdf. file and into the dwg. file. The problem that I'm having is that when trying to move around in the pdf. file to trace my lines it is unbelievely slow and I think I have a decent computer setup. I checked the size of the pdf. file after importing it to CA and it's about 2.5 megs. The pdf. file before importing was 1.2 megs. Is there a better way to go about getting the info I need from the pdf. file to the dwg. file? I had seached to see if this has been brought up before and found a thread where the sloweness was noted, but it wasn't quite the same situation. It would be great if I had a dwg. file of the industrial lot, but that doesn't seem possible at this time.
