SECTION 785:25-5-3. Content of plans and specifications

(a)   The plans and specifications shall, as a minimum, include the following:

(1)   A topographic map of the dam site showing the location of spillway and outlet works. The map shall also show all contiguous property and the owners thereof. The topographic maps for low hazard dams are not required to show test borings, test pits and borrow pits.

(2)   A profile along the dam axis showing the location, elevation, depth of borings or test pits including logs or bore holes and/or test pits, provided that plans and specifications for low hazard dams are not required to contain such a profile.

(3)   A maximum cross-section of the dam showing elevation and width of crest, slopes of upstream and downstream faces, thickness of riprap, zoning of earth embankment, location of cutoff and bonding trenches, elevations, size and type of outlet conduit, valves and operating mechanism.

(4)   Area and capacity curves of the proposed reservoir.

(5)   Detailed drawings showing plans, cross and longitudinal sections of the outlet conduits, valves and controls for operating the same, and trash racks.

(6)   The discharge capacity in cubic feet per second of the spillway for each foot in water depth above the spillway crest up to the maximum high water level and the formula used in making such determinations.

(7)   Detailed plans of spillway structures, cross-section of the channel leading to and from the spillway, spillway profile, and procedures for operation of the spillway structure.

(8)   Hydrologic and hydraulic analysis report as described in the publication Hydrologic and Hydraulic Guidelines for Dams in Oklahoma, Oklahoma Water Resources Board, Dam Safety Program, August 2011.

(9)   A requirement, during the period of construction, for supervision by an engineer as required in 785:25-7-2.

(10)   A provision that the plans and specifications may not be substantially changed or changed in any material respect without prior written consent of the Board.

(11)   A provision stating in detail all matters necessary to ensure that construction is accomplished in a responsible manner and that needed control is exercised by an engineer as required in 785:25-7-2 to ensure construction of a safe structure.

(b)   The size of all plans and maps filed shall not be more than 11" x 17" and shall be drawn with an adequate number of views, in proper dimensions, and to a sufficiently large scale so that the plans and maps may be readily interpreted and studied. In addition to the plans and maps required to be filed, if plans and maps larger than 11" x 17" are submitted for review purposes, the larger plans and maps will not be retained by the Board.
