For the purposes of this chapter, the following definitions are adopted:
BASE FLOOD: The flood having a one percent (1%) probability of being equaled or exceeded in any given year. The base flood is also known as the 100-year flood. The base flood elevation at any location is as defined in section 11-1-3 of this chapter.
BASE FLOOD ELEVATION (BFE): The elevation in relation to mean sea level of the crest of the base flood.
BUILDING: A structure that is principally aboveground and is enclosed by walls and a roof including manufactured homes, prefabricated buildings, and gas or liquid storage tanks. The term also includes recreational vehicles and travel trailers installed on a site for more than one hundred eighty (180) days per year.
CRITICAL FACILITY: Any public or private facility which, if flooded, would create an added dimension to the disaster or would increase the hazard to life and health. Examples are public buildings, emergency operations and communication centers, healthcare facilities and nursing homes, schools, and toxic waste treatment, handling or storage facilities.
DEVELOPMENT: A. Any manmade change to real estate including, but not necessarily limited to:
1. Demolition, construction, reconstruction, repair, placement of a building, or any structural alteration to a building;
2. Substantial improvement of an existing building;
3. Installation of a manufactured home on a site, preparing a site for a manufactured home, or installing a travel trailer on a site for more than one hundred eighty (180) days per year;
4. Installation of utilities, construction of roads, bridges, culverts or similar projects;
5. Construction or erection of levees, dams, walls, or fences;
6. Drilling, mining, filling, dredging, grading, excavating, paving, or other alterations of the ground surface;
7. Storage of materials including the placement of gas and liquid storage tanks; and
8. Channel modifications or any other activity that might change the direction, height, or velocity of flood or surface waters.
B. "Development" does not include routine maintenance of existing buildings and facilities; resurfacing roads; or gardening, plowing, and similar practices that do not involve filling, grading, or construction of levees.
FEMA: Federal emergency management agency.
FLOOD: A general and temporary condition of partial or complete inundation of normally dry land areas from the overflow, the unusual and rapid accumulation, or the runoff of surface waters from any source.
FLOOD FRINGE: That portion of the floodplain outside of the regulatory floodway.
FLOOD INSURANCE RATE MAP: A map prepared by the federal emergency management agency that depicts the floodplain or special flood hazard area (SFHA) within a community. This map includes insurance rate zones and may or may not depict floodways and show base flood elevations.
FLOOD PROTECTION ELEVATION OR FPE: The elevation of the base flood plus one foot (1') of freeboard at any given location in the floodplain.
FLOODPLAIN AND SPECIAL FLOOD HAZARD AREA (SFHA): Are synonymous. Those lands within the jurisdiction of the village, the extraterritorial jurisdiction of the village, or that may be annexed into the village that are subject to inundation by the base flood. The floodplains of the village are generally identified as such on the countywide flood insurance rate map of Sangamon County, Illinois, prepared by the federal emergency management agency and dated May 3, 2004. "Floodplain" also includes those areas of known flooding as identified by the community.
FLOODPROOFING: Any combination of structural or nonstructural additions, changes, or adjustments to structures which reduce or eliminate flood damage to real estate, property and their contents.
FLOODPROOFING CERTIFICATE: A form published by the federal emergency management agency that is used to certify that a building has been designed and constructed to be structurally dry floodproofed to the flood protection elevation.
FLOODWAY: That portion of the floodplain required to store and convey the base flood. The floodway for the floodplains of Horse Creek and Henkle Branch shall be as delineated on the countywide flood insurance rate map of Sangamon County, Illinois, prepared by FEMA and dated May 3, 2004. The floodways for each of the remaining floodplains of the village shall be according to the best data available from federal, state, or other sources.

SFHA: See definition of Floodplain And Special Hazard Area (SFHA).
SUBSTANTIAL DAMAGE: Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damage condition would equal or exceed fifty percent (50%) of the market value of the structure before the damage occurred regardless of actual repair work performed. Volunteer labor and materials must be included in this determination.
SUBSTANTIAL IMPROVEMENT: Any reconstruction, rehabilitation, addition, or improvement of a structure, the cost of which equals or exceeds fifty percent (50%) of the market value of the structure before the improvement or repair is started, "substantial improvement" is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include either: a) any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions or b) any alteration of a structure listed on the National Register of Historic Places or the Illinois Register of Historic Places.
