The level of service standard to determine what is acceptable or unacceptable traffic flow on streets shall be based on a volume to capacity ratio. City streets shall maintain a LOS of “D,” as defined by the Highway Capacity Manual (2000 Edition), during the p.m. peak hour of the day. A lesser standard may be accepted for local street intersections or driveway access points that intersect with collector or arterial streets, if alternative signalized access is available and these intersections are found to operate safely. (Ord. 1919 § 6, 2004)
