(a) Drawings. The construction drawings shall be made with India ink or some other equally substantial and distinct material from which clear and legible prints may be obtained. Freehand linear drawings shall not be attempted, nor should other principles of good surveying, engineering or draftsmanship be offended. The sheets upon which the construction drawings are made shall measure either 22 by 36 or 24 by 36 inches. A poorly drawn or illegible plan is sufficient cause for rejection.
(b) Title. The title of the plan shall contain the name of the subdivision, road or street names, township, county and location plat. Space shall be provided on the title sheet or the first sheet of the plan for approval by the proper authorities.
(c) Typical Sections. The typical sections shall meet the specifications as set forth by the City Engineer. Curb and gutter shall be required as part of any road or street construction if, in the opinion of the City Engineer, such type of construction is deemed desirable.
(d) Plan and Profile Views.
(1) The plan view shall be drawn to a scale of 1 inch to 50 feet; 1 inch to 80 feet; 1 inch to 100 feet. The scale of 1 inch to 100 feet shall be used only with the approval of the City Engineer or his representative in advance of the plan preparation. The plan view shall show the proposed road, street, or alley alignment, right-of-way and pavement widths, center lines, bearings, stationing, curve of radius data, existing and proposed drainage. Any other significant feature or factor shall also be shown on the plans. The center line of road, street or alley construction shall coincide with the center line of the right of way. Any changes from same shall be at the discretion of the City Engineer.
(2) The profile view shall have a horizontal scale of 1 inch to 50 feet; 1 inch to 80 feet; 1 inch to 100 feet; a vertical scale of 1 inch to 5 feet; 1 inch to 6 feet; 1 inch to 10 feet. The horizontal scale of 1 inch to 100 feet and vertical scale of 1 inch to 10 feet shall be used only with the approval of the City Engineer in advance of the plan preparation. The existing and proposed center line profile, elevations, gradient, existing and proposed drainage lines and vertical curves shall be shown. The maximum street gradient shall be seven percent (7%), the minimum street gradient shall be 0.30 percent. Any change from same shall be with the approval of the City Engineer. When establishing road, street or alley gradients, fullest consideration shall be given the abutting property.
(3) Vertical curves shall be used at all points on the gradient where the algebraic difference is one percent (1%) or greater. The minimum length of any vertical curve shall be 100 feet.
(4) The minimum non-passing sight distance shall be 200 feet on vertical curves.
