(A) Authority. This chapter is adopted pursuant to the powers granted by 65 ILCS 5/1-2-1, 11-12-12, 11-30-2, 11-30-8, and 11-31-2.
(B) Purpose. This chapter is adopted for the following purposes:
(1) To prevent unwise developments from increasing the flood or drainage hazard to others;
(2) To protect new buildings and major improvements to buildings from flood damage;
(3) To protect human life and health from the hazards of flooding;
(4) To lessen the burden on the taxpayer for flood control projects, repairs to flood-damaged public facilities and utilities, and flood rescue and relief operations;
(5) To maintain property values and a stable tax base by minimizing the potential for creating flood blight areas;
(6) To make federally subsidized flood insurance available for property in the village; and
(7) To provide for the orderly growth and development of an environment that is especially sensitive to changes from human activity.
(A) All new development proposals in the special flood hazard areas shall be reviewed and approved by the responsible village official.
(B) This review is to ensure the following:
(1) New development will not change the flow of flood or other surface drainage waters so that other properties become more susceptible to damage;
(2) New developments will not create special hazards or nuisances when flooded; and
(3) New buildings and major improvements to existing buildings will not be subject to damage by the base flood.
For the purpose of this chapter the following definitions shall apply unless the context clearly indicates or requires a different meaning.
ASC or AREA OF STATE CONCERN. That portion of riverine SFHAs where permits are required. The ASC for the village is generally identified as such on the Area of State Concern Map of the village identified in Title XVII of this code of ordinances.
BASE FLOOD or 100-YEAR FLOOD. The flood having a 1% probability of being equaled or exceeded in any given year. The base flood elevation at any location is as defined in § 151.04 below.
BUILDING. A structure that is principally above ground and is enclosed by walls and a roof. The term includes a gas or liquid storage tank in order that such tanks will be constructed to the same flood damage protection standards. The term also includes recreation vehicles and travel trailers which have been installed on a site for more than 180 days.
DEVELOPMENT.
(1) Any manmade change to real estate, including:
(a) Construction, reconstruction, or placement of a building or an addition to a building valued at more than $1,000;
(b) Drilling, mining, installing utilities or facilities, construction of roads, bridges, or similar projects valued at more than $1,000;
(c) Construction or erection of levees, walls, or fences;
(d) Filling, dredging, grading, excavating, or other nonagricultural alterations of the ground surface;
(e) Storage of materials; or
(f) Any other activity that might change the direction, height, or velocity of flood or surface waters.
(2) DEVELOPMENT does not include:
(a) The maintenance of existing building and facilities, such as reroofing or resurfacing roads;
(b) Repairs made to a damaged building that do not change the building’s exterior dimensions and that are valued at less than 50% of the value of the building before the damage occurred; or
(c) Gardening, plowing, and similar agricultural practices that do not involve filling, grading, or construction of levees.
FLOOD. A general and temporary condition of inundation of normally dry land areas from the overflow, the unusual and rapid accumulation, or the runoff of surface waters from any source.
FLOODWAY. That portion of the SFHA required to store and convey the base flood. If not prohibited, building or placing obstructions in a floodway will increase flood damages to other properties.
FPE or FLOOD PROTECTION ELEVATION. The elevation of the base flood, plus 1 foot, at any given location in the SFHA.
MOBILE HOME. Includes mobile homes, manufactured homes and pre-fabricated buildings.
SFHA or SPECIAL FLOOD HAZARD AREA. Those lands within the jurisdiction of the village that are subject to inundation by the base flood. The SFHAs of the village are generally identified as such on the flood insurance rate map of the village identified in Title XVII of this code of ordinances.
(A) This chapter’s protection standard is the base flood according to the best data available to the State Water Survey’s Floodplain Information Repository. Whenever a party disagrees with the best available data, that party may finance the detailed engineering study needed to replace existing data with better data and submit it to the State Water Survey.
(B) The base flood elevation for the SFHAs of the village shall be as delineated on the 100-year flood profiles in the Flood Insurance Study of the village prepared by the Federal Insurance Administration identified in Title XVII of this code of ordinances.
