§ 3.1.3. Street Cross Flow
Latest version.
Whenever storm runoff, other than limited sheet flow, moves across a traffic lane, a serious and dangerous impediment to traffic flow occurs. Cross-flow is allowed only in case of superelevation of a curve or overflow from the higher gutter on a street with cross fall. No more than three (3) cubic feet per second for the 25 year storm shall be allowed to cross flow from the higher elevation to the lower elevation.
