§ 15-1923. Plans and estimates.

The department may make a study of the works necessary to drain the
district and prepare maps, plans, estimates and reports showing a
complete system of drainage therefor, the estimated cost of the various
ditches and other works and parts thereof and the boundaries of the land
which will be served by and therefor should contribute to the cost of
each structure. These estimates of costs shall be made on the assumption
that no drainage work has ever been done in the district. In addition
the department may show on the plans any drainage work which has
heretofore been done in the district, may estimate the cost of those
works on the same basis used for the estimate of the cost of the
proposed system and in similar manner may determine the boundaries of
the land served by the existing ditches.
