<br />* Error in survey
<br />This survey was conducted on July 29th and 30th, 1986.
<br />Although points lw-P. through I5W-R are higher than the mean
<br />average, this data still illustrates no subsidence has
<br />occurred. The eight points in this area are consistently .32
<br />feet higher than the mean elevation. It is evident an error
<br />in measuring the height of instrument or height of rod is the
<br />discrepancy.
<br />The points HW11 through HW21 illustrate that no subsidence has
<br />occurred along Y.ighway 151. The small changes can be
<br />attributed to the ground settling.
