Section 2. Definitions.
For the purposes of this ordinance, 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 3 of this ordinance.
Base Flood Elevation (BFE)- The elevation in relation to mean sea level of the crest of the base flood.
Basement- That portion of a building having its floor sub-grade (below ground level) on all sides.
Building- A walled and roofed structure, including gas or liquid storage tank, that is principally above ground, 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 facility which is critical to the health and welfare of the population and, if flooded, would create an added dimension to the disaster. Damage to these critical facilities can impact the delivery of vital services, can cause greater damage to other sectors of the community, or can put special populations at risk.
Examples of critical facilities where flood protection should be required include: emergency services facilities (such as fire and police stations), schools, hospitals retirement homes and senior care facilities, major roads and bridges, critical utility sites (telephone switching stations or electrical transformers, and hazardous material storage facilities (chemicals, petrochemicals, hazardous or toxic substances).
Development- Any man-made 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 channel modifications or any other activity that might change the direction, height, or velocity of flood or surface waters.
"Development" does not include routine maintenance of existing buildings and facilities, resurfacing roads, or gardening, plowing, and similar practices that do not involve filing, grading, or construction of levees.
Existing Manufactured Home Park or Subdivision- A manufactured
home park or subdivision for which the construction of facilities for servicing the lots on which the manufactured homes are to be affixed or buildings to be constructed (including, at a minimum, the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads) is completed before the effective date of the floodplain management regulations adopted by a community.
Expansion to an Existing Manufactured Home Park or Subdivision- The preparation of additional sites by the construction of facilities for servicing the lots on which the manufactured homes are to be affixed (including the installation of utilities, the construction of streets, and either final site grading or the pouring of concrete pads).
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.

SFHA- See definition of floodplain.
Start of Construction- Includes substantial improvement and means the date the building permit was issued, ills, provided the actual start of construction, repair, reconstruction, rehabilitation, addition placement or other improvement, was within one hundred eighty (180) days of the permit date. The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of colunins.or any work beyond the stage of excavation or placement of a manufactured home on a foundation. For a substantial improvement, actual start of construction means the first alteration of any wall, ceiling, floor or other structural part oaf a building whether or not that alteration affects the external dimensions of the building.

This ordinance's protection standard is the base flood. The best available base flood data are listed below. Whenever a party disagrees with the best available data, the party shall finance the detailed engineering study needed to replace the existing data with better data and submit it to the FEMA and IDNR/OWR for approval prior to any development of the site.
A. The base flood elevation for the floodplains of (name of all studied rivers, creeks and streams) shall be as delineated on the 100-year flood profiles in the countywide Flood Insurance Study of McLean prepared by the Federal Emergency Management Agency and (date of Flood Insurance Study).
B. The base flood elevation for each of the remaining floodplains delineated as a "A Zone" on the countywide Flood Insurance Rate Map of McLean County, Illinois shall be according to the best data available from federal, state or sources. Should no other data exist, an engineering study must be financed by the applicant to determine base flood elevations.

K. cooperate with state and federal floodplain management agencies to coordinate base flood data and to improve the administration of this ordinance;
L. maintain for public inspection base flood data, floodplain maps, copies of state and federal permits, and documentation of compliance for development activities subject to this ordinance;
M. perform site inspections to ensure compliance with this ordinance and make substantial damage determinations for structures within the floodplain, and
N. maintain the accuracy of floodplain maps including notifring IDNR/OWR and/or submitting information to FEMA within six months whenever a modification of the floodplain may change the base flood elevation or result in a change to the floodplain map.
Section 5. Development Pennit.
No person, firm, corporation, or governmental body not exempted by law shall commence any development in the floodplain without first obtaining a development permit from the (title of local official responsible for this ordinance). The (title of local official responsible for this ordinance) shall not issue a development permit if the proposed development does not meet the requirements of this ordinance.
A. The application for development permit shall be accompanied by:
1. drawings of the site, drawn to scale showing property line dimensions;
2. existing grade elevations and all changes in grade resulting from excavation or filling;
3. the location and dimensions of all buildings and additions to buildings;
4. the elevation of the lowest floor (including basement) of all proposed buildings subject to the requirements of Section 7 of this ordinance, and
5. cost of project or improvements as estimated by a licensed engineer or architect. A signed estimate by a contractor may also meet this requirement.
B. Upon receipt of an application for a development permit, the (title of local official responsible for this ordinance) shall compare the elevation of the site to the base flood elevation. Any development located on land that can be shown by the base flood elevation. Any development located on land that can be shown by survey data to be higher than the current base flood elevation and which has not been filled after the date of the site's first Flood Insurance Rate Map is not in the floodplain and therefore not subject to the requirements of this ordinance. Conversely, any development located on land shown to be below the base flood elevation and hydraulically connected, but not shown on the current Flood Insurance Rate Map, is subject to the provisions of this ordinance.
The (title of local official responsible for this ordinance) shall maintain documentation of the existing ground elevation at the development site and certification that this ground elevation existed prior to the date of the site's first Flood Insurance Rate Map identification.
The (title of local official responsible for this ordinance) shall be responsible for obtaining from the applicant copies of all other federal, state, and local permits, approvals or permit-not-required letters that may be required for this type of activity. The (title of local official responsible for this ordinance) shall not issue a permit unless all other federal, state, and local pemiits have been obtained.
