(A) All changes in street grades shall be connected by vertical curves of a minimum length in feet equivalent to the algebraic difference in the percent of grade times a K factor, such K factor to be derived as follows:
Design Speed | K Factor | |
Crest Curve | Sag Curve | |
20 | 10 | 15 |
25 | 15 | 20 |
30 | 30 | 35 |
35 | 45 | 45 |
(B) No vertical curves shall be required on minor streets or collector streets where the algebraic difference in percent of grade is less than 2%.
