   The final plat shall conform to the dimensions for all lines, angles, and curvatures, with functions used to describe all boundaries, including the perimeter survey of tracts, streets, alleys, easements, areas to be reserved for public use, and other important features. Error of the closure of boundary-line surveys shall not exceed one in 10,000 (one foot for each 10,000 feet of perimeter survey). Angular error shall not exceed plus or minus 20 seconds. Lot lines are to show dimensions in feet and hundredths, and when an angle occurs in any lot line between lot corners, the measurement of the angle shall be shown in degrees, minutes, and seconds. The area of each lot is to be shown individually in square feet.
   (B)   An identification system for all lots and blocks.
   (C)   True angles and distances to the nearest established street lines and official monuments (not less than 3), which shall be accurately described in the plat by location, size, and elevation.
   (D)   Municipal, township, county, or section lines accurately tied to the lines of the subdivision by distances and angles.
   (E)   Accurate location of all monuments, which shall be placed at all block corners and angle points, and at intermediate points as shall be required by the city. The monuments shall be of a permanent character, as determined by the city engineer, and installed in such a manner that they may be found by a licensed surveyor. All U.S.G.S., state, county, city, or other official benchmarks, monuments, or triangulation stations in or adjacent to the property shall be preserved in a precise position.
   (F)   Accurate outlines and legal descriptions of any areas to be dedicated or reserved for public use, or for the exclusive use of property owners within the subdivision, with the purposes indicated thereon.
   (G)   Protective covenants shall be lettered on the final plat or appropriately referenced thereon.
