with the owners' names so far as they can be learned, that will be affected
thereby, and such other information as they may have collected that will
tend to show the correctness of their findings.

An. Code, sec. 81D. 1912, ch. 656, sec. 4.

87. The Board of County Commissioners shall consider this report at
their first meeting. The engineer and other two viewers being present. If
the viewers report that the drainage is not practicable or that it will not
benefit the public health, or any public highway, or be conducive to the
general welfare of the community, and the Board of County Commissioners
shall approve such finding, the petition shall be dismissed at the cost of
the petitioners. If the report of the viewers is favorable to the project and
the Board of County Commissioners shall so find after hearing all the
evidence, they shall make such recommendations as they think proper to
the viewers, and direct them to make a complete survey, plans and specifica-
tions, and estimate of cost for the tiles, drains or levees, or other improve-
ments, and fix a time when said engineer and viewers shall complete and
file their final reports, not exceeding sixty days, unless extended by the
commissioners in writing.

An. Code, sec. 81E. 1912, ch. 656, sec. 5.

88. The engineer and viewers shall have power to employ such assist-
ants as may be necessary to make a complete survey of the drainage district,
and shall enter upon the ground and make a survey of the main drain or
drains and all their laterals. The line of each ditch, drain or levee shall
be plainly and substantially marked on the ground. The course and distance
of each ditch shall be carefully noted and sufficient notes made, so that it
may be accurately platted and mapped. A line of levels shall be run for
the entire work and sufficient data secured from which accurate profiles and
plans may be made for each of the proposed drains or levees. Frequent
bench marks shall be established along the line, on permanent objects, and
their elevation and full description recorded in the field books and their
location shown on the map. If it is deemed expedient by the engineer and
viewers, other levels may be run to determine the fall from one part of the
district to another. If no old water course, ditch or channel is being
widened, deepened or straightened, it shall be accurately cross-sectioned, so
as to compute the amount of cubic yards saved by the use of such old
channel. A drainage map of the district shall then be completed, showing
the location of the ditch or ditches and other improvements, and the bound-
ary, as closely as may be determined by the records, of the lands owned by
such individual landowner within the district. The location of any rail-
roads or public highways and the boundary of any incorporated towns or
villages within the district shall be shown on the map. There shall also be
prepared to accompany this map a profile of each levee, drain or water
course, showing the surface of the ground, the bottom or grade of the pro-
posed improvement and the number of cubic yards of excavation or fill in
each mile or fraction thereof, and the total yards in the proposed improve-
ment and the estimated cost thereof, and plans and specifications and the
cost of any other work required to be done.
