Section 15-1959. Corrections and revisions of assessments, determinations of drainage enhancements and apportionment of costs

1. In the  event  that  obvious  errors  or  discrepancies  should  be
  discovered  in any assessment, determination of drainage enhancements or
  general or special apportionments of cost, the  department  may  correct
  the same by filing corrected copies of the statement of such assessment,
  determination or apportionments and following the procedure specified in
  title 19 of this article.
    2.  Should  such  corrections  be made, the county legislative body is
  empowered to levy additional sums  on  or  to  give  credit  to  certain
  parcels  to  the end that the amount collected from each parcel shall be
  what it should have  been  had  an  error  not  been  made.  The  county
  legislative  body  is  also  empowered to apply to the department for an
  adjustment of assessments among the various parts into which an original
  parcel may have subdivided.
    3. The department shall file and record its findings in such cases  as
  amendments  to  the  original  or  corrected assessments, and shall give
  notice to the parties affected, but need hold no hearing thereon  unless
  such  hearing  be  demanded  by  a  party affected within ten days after
  notice is given.
    4.  None  of  the  above  proceedings  shall  be  held  to  reopen   a
  determination  of enhancements or an apportionment of cost, except as to
  the particular matter involved. Should the department at any  time  find
  that  a  former  assessment, determination or apportionment appears with
  the lapse of time or in the light of new  knowledge  and  experience  to
  have  become inequitable, it may so declare by written order and proceed
  to review the whole matter by following the full procedure laid down  in
  whichever  one  of  the  following  sections  is appropriate:   15-1919,
  15-1925, 15-1937 or 15-1939.
