(A) All changes of grade shall be connected by vertical curves of a minimum length in feet equal to 20 times the algebraic difference in the rate of grade for arterials and industrial streets; for collector and local streets, 15 times.
(B) Minimum vertical visibility shall conform to the Ohio Department of Transportation's regulations in effect on the date of the approval of the preliminary plat.
(C) Longitudinal grades should be provided to facilitate surface drainage. A minimum grade for the usual case is 0.5%, but a grade of 0.30% may be used where there is a high-type pavement accurately crowned and supported on firm subgrade. Street grades shall not exceed 3% within 100 feet of an intersection.
