(a) The minimum right-of-way width for minor streets shall be fifty (50) feet. The minimum right-of-way width for collector streets, industrial streets and multiple dwelling streets shall be sixty (60) feet. The minimum right-of-way width for major streets shall be 100 feet. The Commission may recommend, and Council may require, wider right of way when warranted for the welfare of the City.
(b) Streets that are obviously in alignment with others already exiting and named shall bear the names of the existing streets.
(c) Streets shall be laid out to intersect as nearly at right angles as possible.
(d) The maximum grade of streets shall be twelve percent (12%); the minimum grade shall be eight tenths percent (0.8%). Changes in grade of major and collector streets shall be connected by vertical curves of a minimum length equal to fifteen (15) times the algebraic difference between the rates of grade (in feet per hundred); one-half that minimum for minor streets. The minimum horizontal alignment standard, radii of center line curvature, shall be 500 feet for major streets, 200 feet for collector streets and 100 feet for minor streets. A tangent at least 100 feet long shall be used between reverse curves on all except minor streets; in any case, the standard used shall be adequate to ensure safe visibility.
(e) At street intersections, property line corners shall be rounded by arcs having a minimum radius of fifteen (15) feet. Street curbs or the edges of street pavements shall be rounded by arcs having a minimum radius of twenty-five (25) feet for streets twenty-eight (28) feet wide and thirty-five (35) feet for street thirty-seven (37) feet wide. These minimum radii shall be increased where the angle of intersection is less than sixty (60) degrees, or in other cases where the Commission may determine that an increase is necessary.
(f) Alleys are not permitted.
(g) Easements of not less than seven and one-half (7½) feet in width shall be provided where necessary on each side of all rear lot lines and/or alongside lot lines for poles, wires, conduits, storm and sanitary sewers, gas, water and other utility mains. Easements of greater width may be required along or across lots where necessary for the extension of main storm and sanitary sewers and other utilities, and where both water and sewer lines are located in the same easement.
