Here is the average height above ground for the new site.

Also Nate, Al is working to get you the rest of the information.

Antenna Height Above Average Terrain Calculations -- Results
<https://www.fcc.gov/encyclopedia/antenna-height-above-average-terrain-haat-calculator>
Input Data    Latitude      *42° 41' 15"* North
    Longitude   *92° 25' 10"* West    (NAD 83)

    These coordinates convert to NAD 27 coordinates of
      42° 41' 15.06", North, 92° 25' 09.34" West (NAD 27).

    Height of antenna radiation center above mean sea level: *306* meters
AMSL

    Number of Evenly Spaced Radials = *36*       0° is referenced to True
