Definitions: For the purposes of this section, the following definitions
are adopted:
BASE FLOOD
The flood having a 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 Subsection
(C) of this section.
BASEMENT
That portion of a building having its floor subgrade (below
ground level) on all sides.
BUILDING
A walled and roofed structure, including gas or liquid storage
tank that is principally aboveground 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 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
1.
Any manmade change to real estate including, but not necessarily
limited to:
(a)
Demolition, construction, reconstruction, repair, placement
of a building, or any structural alteration to a building;
(b)
Substantial improvement of an existing building;
(c)
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 180 days per year;
(d)
Installation of utilities, construction of roads, bridges, culverts
or similar projects;
(e)
Construction or erection of levees, dams, walls or fences;
(f)
Drilling, mining, filling, dredging, grading, excavating, paving,

buildings and facilities, resurfacing roads, or gardening, plowing,
and similar practices that do not involve filling, 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

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

a community. This map includes insurance rate zones and may or may
not depict floodways and show base flood elevations.
FLOOD INSURANCE STUDY

and, if appropriate, corresponding water surface elevations.
FLOODPLAIN AND SPECIAL FLOOD HAZARD AREA (SFHA)
These two terms are synonymous. Those lands within the jurisdiction
of the City of Lincoln, the extraterritorial jurisdiction of the City

City of Lincoln are generally identified as such on panel number(s)
17107C0145 and 17107C0165 of the countywide flood insurance rate map
of Logan County prepared by the federal emergency management agency
and dated February 18, 2011. Floodplain also includes those areas
of known flooding as identified by the community.
The floodplains of those parts of unincorporated Logan County
that are within the extraterritorial jurisdiction of the City of Lincoln
or that may be annexed into the City of Lincoln are generally identified
as such on the flood insurance rate map prepared for Logan County
by the federal emergency management agency and dated February 18,
2011.
FLOODPROOFING
Any combination of structural or nonstructural additions,
changes, or adjustments to structures which reduce or eliminate flood

the base flood. The floodway for the floodplains of Brainard's
Branch shall be as delineated on the countywide flood insurance rate
map of Logan County prepared by FEMA and dated February 18, 2011.
The floodways for each of the remaining floodplains of the City of
Lincoln shall be according to the best data available from federal,
state, or other sources.
FREEBOARD
An increment of elevation added to the base flood elevation
to provide a factor of safety for uncertainties in calculations, future
watershed development, unknown localized conditions, wave actions
and unpredictable effects such as those caused by ice or debris jams.
HISTORIC STRUCTURE
Any structure that is:
1.
Listed individually in the national register of historic places
or preliminarily determined by the secretary of the interior as meeting
the requirements for individual listing on the national register.

interior as contributing to the historic district or a district preliminarily
determined by the secretary to qualify as a registered historic district.

on or after the effective date of floodplain management regulations
adopted by a community and includes any subsequent improvements of
such structures.
NEW MANUFACTURED HOME PARK OR SUBDIVISION

(SFHA).
START OF CONSTRUCTION
Includes substantial improvement and means the date the building
permit was issued. This, provided the actual start of construction,
repair, reconstruction, rehabilitation, addition placement or other
improvement, was within 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 columns 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 of a building whether or not that alteration affects the external
dimensions of the building.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a structure whereby the
cumulative percentage of damage subsequent to the adoption of this
section equals or exceeds 50% of the market value of the structure
before the damage occurred regardless of actual repair work performed.

The term includes "repetitive loss buildings" (see definition).
SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition or improvement
of a structure taking place subsequent to the adoption of this section
in which the cumulative percentage of improvements:
1.
Equals or exceeds 50% of the market value of the structure before
the improvement or repair is started, or
2.
Increases the floor area by more than 20%.
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. This term includes structures which have incurred repetitive
loss or substantial damage, regardless of the actual repair work done.
The term does not include:
1.
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
2.
Any alteration of a structure listed on the national register
of historic places or the Illinois register of historic places.
VIOLATION
The failure of a structure or other development to be fully
compliant with the community's floodplain management regulations.
A structure or other development without the required federal, state,
and/or local permits and elevation certification is presumed to be
in violation until such time as the documentation is provided.
