- Flood insurance is mandatory for structures in Special Flood Hazard Areas
- Floodway – In the floodway, communities must prohibit encroachments, including fill, new construction, substantial improvements, and other development within the adopted floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in ANY increase in flood levels within the community during the occurrence of the base flood discharge.
- BFE – Base Flood Elevation, the computed elevation to which floodwater is anticipated to rise during the base flood is the 100-year flood elevation
- 100-year flood(Base Flood) – is the flood that has a 1% chance of occurring or being exceeded in any given year.
As per Drainage Ordinance O-112-2007:
“Any structure, enclosed on three or more sides, built on property in the one hundred (100) year Flood Zone shall be elevated so as to insure the lowest floor of such structure is located at a minimum of (1’) foot above the base flood elevation height for that area at that time.” Attached garages, carports, and porches shall be located at a minimum of six (6”) inches above the base flood elevation height.
