All streets under the jurisdiction of the city shall be classified by the city and the classification shall determine the standards to which the streets must be constructed. If the proper classification of any street is unknown, or if a new street is proposed for construction, the city shall review the existing or proposed street and thereafter establish a classification using the criteria listed in § 153.008 for local, collector, and arterial streets, or according to the city’s “Future Land-Use Plan.”

(B) Measurement of pavement width for streets shall be made from back-to-back of the curbs. Measurement of pavement width for alleys, where curbs are not required, shall be from edge to edge.
