1. (a) Construction plans requiring approval by the executive director may include the following, as determined by the executive director:

   1. (1) a topographic map of the dam site with contour intervals of not to exceed five feet. A plan of the dam shall be superimposed on this map showing the location of spillways, outlet conduit, cutoff walls, and other structures;
   2. (2) a profile of the dam site taken on the long axis of the dam and a profile of each spillway along its long axis. The profile shall also show the location of the outlet conduit and spillway. A log showing the classification of materials encountered below the surface as shown by test pits or borings should be included;
   3. (3) a cross section of the dam at maximum section showing complete details and dimensions;
   4. (4) detailed plans showing sections of outlet conduits, control works, and spillways. These sections should be of sufficient number and detail to delineate clearly all features of the structure; and
   5. (5) the indicated location of all permanent instrumentation. All pressure cells, settlement plates, piezometers, slope indicator casing or other devices shall also be noted.

2. (b) Construction plans shall be accompanied by specifications which may include, but are not limited to, the following:

   1. (1) the requirements for the various types of materials to be used in the construction of all pertinent works;
   2. (2) a specified time of completion, i.e., a requirement that the contractor's bid contain a time of completion;
   3. (3) a provision to the effect that plans and specifications shall not be substantially or materially altered without prior written approval of the executive director.
3. (c) Other engineering reports and additional information are sometimes prepared and may be required by the executive director for review. These reports, applicable to the type of structure (earthfill, rockfill, or concrete) in question, may include details such as geology of the project site and vicinity, location and logs of test borings, pits and shafts, results of field and laboratory tests on structural and foundation materials; seepage studies, and stability analyses of embankments, spillways, retaining walls, etc. Additional information required may include recommendations concerning embankment slopes, crest width, berms, core trench depths, moisture-density and strength requirements, minimum compressive strength for concrete, construction sequence procedures, and/or techniques for excavations and embankments, and types of compaction equipment, borrow excavation techniques, and sequence of fill placement.
