In approving a tentative map, the commission or council may grant a suspension of any of the subdivision requirements set forth or referred to in this chapter, except underground facilities which may be waived only by the council; provided such suspensions are not inconsistent with state law. A variance from the lot area, frontage, width, depth and front yard or setback requirements of the various zones set forth in this code, may also be granted by the commission or the council. If such suspension or variance is requested, a public hearing shall be conducted as provided in section 10-3-6 of this title. The time limits established in section 10-8-9 of this chapter may be extended by mutual consent of the subdivider and the commission or council as appropriate. (Ord. 1152, 4-25-1978)
