  2. B.
    City Administered Street Construction:  Street and thoroughfare construction projects administered and constructed directly by the City shall comply with this Ordinance, except that compliance is not required for street and thoroughfare construction:  (1) that would be exempt under the standard exceptions in Section 16.210.030A of this Chapter; and (2) that will maintain, enhance, or reconstruct existing roadways, including the intersection improvements, turn lane additions, safety improvements, or new entrances, but which will not add additional through lanes.
