    Converted CAD shapefiles seeminlgy lacking all spatial reference

      Hello Y'all!

      My name is Adam Alsamadisi, I am a student at Rhodes College in Memphis, Tennessee, currently doing research with the Memphis Zoo. With GIS, I am currently creating an information system of the Zoo's Light, Gas, Electric, and Sanitation lines. I have taken the data from their CAD origins (.dwg) to shapefiles (polygons and polylines). I am currently projecting them with the following specifications

      Projected Coordinate System: WGS_1984_BLM_Zone_15N_ftUS
      Central_Meridian: -93.00000000
      Linear Unit: Foot_US

      Geographic Coordinate System:GCS_WGS_1984
      Datum: D_WGS_1984
      Prime Meridian: Greenwich
      Angular Unit: Degree

      Unfortunately though, it does not appear if the layer's information has any spatial significance. I am using UTM because it seems to be the only one that has accurate measurements, but as so far as matching up with ground proofed and reliable data, I'm out of luck. I have tried changing the projections, and for some reason none of the data will georectify as layers (i'm using 9.3).  Does anybody have some suggestions?
