(a) Upon the expiration of the established maintenance period for the base course, the surface course shall be constructed using either asphalt concrete, bituminous mix or portland concrete cement. Specific material and thickness recommendations shall be determined by the City Engineer based upon traffic conditions.
(b) The Planning Commission may recommend to City Council that the surface course requirements be waived in cases where streets within a proposed subdivision plat connect to a public road whose surface is of lesser material than that required by these Regulations and where no specific plan, within two (2) years of approval of final plat, exists for upgrading said public road surface. Streets within the proposed subdivision shall meet or exceed the surface material of said public road. Waiver may not be granted where the proposed density meets or exceeds medium-low density residential as defined in these Regulations.
