Kan. Admin. Regs. § 5-41-1 - Channel changes; plans and specifications
Plans for a channel change shall include the following:
(a) A general location map or aerial
photograph, showing the present alignment of the stream, location of the
proposed channel change, section lines, property lines with names and addresses
of adjoining landowners, drainage area, a north arrow, a bar scale, and any
other prominent features;
(b) a
detailed plan view of the project with stationing shown, including as many
other views as necessary to fully describe the project;
(c) a profile drawing along the centerline of
the proposed new channel. This profile shall extend five times the channel
width upstream and an equivalent distance downstream from each end of the new
channel. The stationing shown on the plan view shall correspond to stationing
on the profile drawing. This drawing shall show the present ground surface, the
present stream bed, and the grade line of the proposed new channel;
(d) cross sections of the existing stream at
locations immediately above and below the proposed channel change. The location
of these cross sections shall be described and shown on the plans. The
elevations of the top of the existing banks and bottom of the channel shall be
shown;
(e) at least one permanent
bench mark conveniently located for use after construction, except for grassed
waterways constructed for the purpose of conveying runoff without causing
erosion or flooding. The location, description, and elevation of the permanent
bench mark, to which all elevations are referred, shall be shown on the plans.
The designer shall reference the project bench mark to the current national
geodetic vertical datum, to a tolerance of plus or minus 1/2 foot on all
channel changes involving perennial streams and where detailed floodplain data
are available. Project datum shall be acceptable on all other channel changes;
and
(f) a cross-sectional drawing
of the proposed new channel, including dimensions.
