Section 15-1963. Formation of district with federal aid

1.  The department may proceed of its own motion to form such district
  and to authorize the proposed work as though petitions therefor had been
  filed as provided in sections 15-1911 and 15-1913  or  15-1931.  It  may
  negotiate   with   the  federal  government,  investigate  the  proposed
  district, study such plans of and reports on the proposed improvement as
  it may find to be available and shall prepare a written  report  thereon
  describing the proposed district, the proposed work, the fixation of the
  district  boundaries,  giving estimates of the cost of the various parts
  of the work which may be a charge against  the  state  or  the  property
  owners in the district and including a determination of enhancements and
  an  apportionment of costs of such a project. Such report shall be filed
  and notice of such filing and of a hearing thereon given as provided  in
  sections 15-0903, 15-1913 and 15-1931.
    2.  After  the final hearing the department shall determine whether it
  is to the public interest to form the district and to proceed  with  the
  work  and, in general terms, what lands will be benefited thereby. These
  matters shall be embodied in a written order, which shall, if the action
  is favorable, form the district, authorize entry  into  agreements  with
  agencies  of the federal government and the doing of whatever is needful
  to carry out the project, all as elsewhere specified in title 19 of this
  article.  Certified copies of the determination and order shall be filed
  and notice of such filing given. Thereupon  such  determination  may  be
  reviewed as provided by section 15-0905, except that the proceedings for
  such  review  must  be  initiated  not  later  than  ten days after such
  filings; otherwise such determination  shall  be  considered  final  and
  conclusive and in due course it shall be recorded. The district shall be
  held  to  have  been  formed  on  the date of such final order, but such
  formation shall not be  effective  until  such  order  shall  have  been
  recorded.
