B. Streets shall be required to intersect one another at right angles or as near to a right angle as practicable in each specific case;

C. Where necessary to give access to or permit a satisfactory future subdivision of adjoining land, streets shall extend to the boundary of the property and the resulting dead-end streets may be approved without a turnaround, provided the control of access across such dead-end street shall be vested in the city. In all other cases, a turnaround having a minimum radius of fifty feet shall be required;

D. Whenever a major street or state highway intersects any other street or highway, the property lines at each block corner shall be rounded with a curve having a radius of not less than thirty feet. At all other intersections, the property line at each block corner shall be rounded with a curve having a radius of not less than twenty feet. In either case, a greater curve radius may be required if streets intersect other than at right angles;

E. The centerline curve radius on all streets and highways shall conform to accepted engineering standards of design and shall be subject to approval by the city engineer but shall be not less than five hundred feet for major streets, three hundred feet for secondary streets and two hundred feet for minor streets;

F. No street or highway shall have a grade of more than twelve percent unless, because of topographical conditions or other exceptional conditions, the city engineer determines that a grade in excess of twelve percent is necessary. No grade shall be less than thirty-hundredths percent;

G. Reserved strips controlling the access to public ways or minimizing values for special improvement assessments will not be approved unless such strips are necessary for the protection of the public welfare or of substantial property rights or both, and in no case, unless the control and disposal of the land comprising such strips is placed definitely within the jurisdiction of the city under conditions approved by the city council;

H. All streets and highways shall be graded and paved to cross-sections and grades approved by the engineer approved by the city council. The subdivider shall improve the extension of all subdivision streets, highways or public ways to the intercepting paving line of any county road, city street, or state highway. Minimum structural design shall be six-inch Type 2 aggregate base, two-inch asphalt concrete. (Ord. 90-1 (part), 1990)
