Such BFE data shall be adopted by reference per Section 41-37 (Ord. of 8-28-1995, § 5.4, eff. 8-28-1995) Sec. 42-94a.

No encroachments, including fill, new construction, substantial improvements and other ~5) developments shall be permitted unless it has been demonsh•ated through hydrologic and hydraulic analyses, performed according to standard engineering practice, that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base ,Flood.
