002.01 An engineer
shall prepare all plans and specifications assisted by qualified engineering
geologist, geotechnical engineers, geologists, and other specialists as
necessary. Plans and specifications submitted to the Department shall be as
detailed as they would be for submission to contractors bidding on the
work.
002.02 Detailed
specifications or references to standard specifications for both materials and
construction aspects shall accompany the plans. The specifications shall be
those currently acceptable and normally used by design and construction
professionals. Material specifications are those specifications which will
cover the materials proposed to be used. Construction specifications are those
specifications describing how the work (construction, enlargement,
reconstruction, alteration, abandonment, breach, or removal) is to be
accomplished, the sequence of procedures to be followed, the limitations, and
the desired results.
002.03 Plans
for construction, enlargement, reconstruction, alteration, abandonment, breach,
or removal of a dam shall conform to the following:
002.03A Be made on sheets with minimum
dimensions of 11 inches by 17 inches and maximum dimensions of 22 inches by 34
inches and shall have adequate margins on all sides.
002.03B Be of such clarity and with distinct
characters of such size as to retain clarity and resolution when reduced to 11
inches by 17 inches. Characters shall not be smaller than one-tenth inch on the
11 inches by 17 inches drawings and two-tenths inch on the 22 inches by 34
inches drawings.
002.04
Plans shall include the following information:
002.04A A map showing the outside limits of
the reservoir water line at maximum storage elevation and at normal storage
elevation, the dam location, the government subdivisions in which the dam and
reservoir are located including the quarter section, section, township, range,
and county; the location and name of any and all streams which are the source
of water or on which the dam is located and, if applicable, the location of any
pump or diversion facility used to provide water to the reservoir.
002.04B The latitude and longitude of the
intersection of the dam centerline with the natural stream channel. Latitude
and longitude must be referenced to the North American Datum of 1983.
002.04C The course of the stream or
watercourse and the drainage area boundary upstream from the proposed or
existing dam.
002.04D The area,
time of concentration and runoff curve number of the drainage basin.
002.04E The elevations, dimensions,
materials, and maximum capacities of all spillways. Elevations shall be
referenced to the North American Vertical Datum of 1988.
002.04F All pertinent hydrologic and
hydraulic data. For each design storm analyzed, indicate the following:
002.04F1 The design rainfall and runoff
amount,
002.04F2 The recurrence
interval,
002.04F3 The peak inflow
into the reservoir,
002.04F4 The
maximum discharge from each spillway,
002.04F5 The peak reservoir elevation and
flow velocity in the auxiliary spillway, and
002.04F6 The results of the auxiliary
spillway stability analysis.
002.04G A topographic map of the dam site and
the return area to the natural channel from all conduits and spillway(s). The
map must be derived from on site or photogrammetric survey and show 2-foot
contour intervals or less.
002.04H
A topographic map of the reservoir within the reservoir area. The map must be
derived from on site or photogrammetric survey and show 2-foot contour
intervals or less.
002.04I A table
showing the reservoir surface area and incremental and cumulative reservoir
storage at 2-foot elevation intervals and at the crest elevation of the
drawdown, principal and auxiliary spillways, other outlets and the top of dam
elevation.
002.04J The cross
sections listed below, with all elevations referred to in the cross sections
referenced to the North American Vertical Datum of 1988 or an assumed
benchmark.
002.04J1 The valley along the
centerline of the dam showing the profile of the top of the dam and the
original ground line;
002.04J2 A
maximum cross section perpendicular to the dam centerline and other
cross-sections or views to clarify construction details;
002.04J3 Other cross-sections, profiles or
plan views showing the location and elevations of the drawdown works, spillways
and other components.
002.04K If there are multiple owners or there
are easements appurtenant to the land where the dam and reservoir are located,
a plan of survey showing the boundary line of each ownership and easement. The
plan of survey shall include labels to indicate separate ownerships or
easements. This drawing must agree with the information provided in the
application described in Chapter 4.001.04 of these rules.
002.04L The certificate of the engineer
responsible for design of the facility. Examples of engineer's certificates are
available on the Department's web site. The engineer's certificate shall
include a designation of the hazard classification for the dam. The certificate
shall be on the first sheet of the drawings.
