§ 151.049  INTERSECTIONS.
   Streets shall intersect as nearly as possible at an angle of 90 degrees and no intersection shall be at any angle of less than 60 degrees. Street curb intersections shall be rounded by radii of at least 20 feet. When the smallest angle of street intersection is less than 75 degrees, the City Council may require curb radii of greater length. Wherever necessary to permit the construction of a curb having a desirable radius without reducing the sidewalk at a street corner to less than normal width, the property line at the street corner shall be rounded or otherwise set back sufficiently to permit the curb construction. No lot or other parcel of land which abuts on and has access to either a collector or a minor street shall have a service drive, curb cut or other means of access to an arterial street within 50 feet of the right-of-way of any street which intersects the arterial street on the side on which the lot or parcel is located.
(Prior Code, § 7.5)
§ 151.050  HORIZONTAL AND VERTICAL STREET CURVES.
   (A)   A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets. Where there is a deflection angle of more than ten degrees in the alignment of a street, a curve with a radius adequate to ensure safe sight distance shall be made. The minimum radii of curves provided shall be required.
   (B)   Every change in grade shall be connected by a vertical curve constructed so as to afford a minimum sight distance of 200 feet, the sight distance being measured from a driver’s eyes, which are assumed to be four and one-half feet above the pavement surface, to an object four inches high on the pavement.
   (C)   Profiles of all streets showing natural or finished grades, drawn to an approved scale, may be required by the city.
(Prior Code, § 7.6)
§ 151.051  STREET GRADES AND ELEVATIONS.
   (A)   All streets shall be designed so as to provide for the discharge of surface water from the pavement and from the right-of-way by grading and drainage. For adequate drainage, the minimum street grade shall not be less than 0.5%. The city shall not approve streets which will be subject to inundation or flooding. All streets must be located at elevations which will make them flood-free in order that portions of the subdivision will not be isolated by floods.
   (B)   Where flood conditions exist, the city shall require profiles or elevations of streets in order to determine the advisability of permitting the proposed subdivision activity. Fill may be used in areas subject to flooding in order to provide flood-free streets if the fill does not increase flood heights. Drainage openings shall be designed so as not to restrict the flow of water and thereby increase flood height.
(Prior Code, § 7.7)
§ 151.052  WIDTHS AND GRADES.
   Right-of-way widths, pavement widths and grades shall be:
