LETTER OF MAP CHANGE (LOMC)
An official Federal Emergency Management Agency determination,
by letter, amending or revising an effective Flood Insurance Rate
Map or Flood Insurance Study. Letters of map change include:
A.
LETTER OF MAP AMENDMENT (LOMA)An amendment based on technical data showing that a property was incorrectly included in a designated special flood hazard area. A LOMA amends the current effective Flood Insurance Rate Map and establishes that a specific property or structure is not located in a special flood hazard area.
B.
LETTER OF MAP REVISION (LOMR)A revision based on technical data that may show changes to flood zones, flood elevations, floodplain and floodway delineations, and planimetric features. A letter of map revision based on fill (LOMR-F) is a determination that a structure or parcel of land has been elevated by fill above the base flood elevation and is, therefore, no longer exposed to flooding associated with the base flood. In order to qualify for this determination, the fill must have been permitted and placed in accordance with the community's floodplain management regulations.
C.
CONDITIONAL LETTER OF MAP REVISION (CLOMR)A formal review and comment as to whether a proposed flood protection project or other project complies with the minimum National Flood Insurance Program requirements for such projects with respect to delineation of special flood hazard areas. A conditional letter of map revision based on fill (CLOMR-F) is a determination that a parcel of land or proposed structure that will be elevated by fill would not be inundated by the base flood if fill is placed on the parcel as proposed or the structure is built as proposed. A CLOMR does not revise the effective Flood Insurance Rate Map or Flood Insurance Study; upon submission and approval of certified as-built documentation, a letter of map revision may be issued by the Federal Emergency Management Agency, to revise the effective Flood Insurance Rate Maps.
LICENSED
Professionals authorized to practice in the State of Maryland
by issuance of licenses by the Maryland Board of Architects, Maryland
Board of Professional Engineers, Maryland Board of Professional Land
Surveyors, and the Maryland Real Estate Appraisers and Home Inspectors
Commission.

of a structure; the floor of an enclosure below the lowest floor is
not the lowest floor, provided the enclosure is constructed in accordance
with these regulations. The lowest floor of a manufactured home is
the bottom of the lowest horizontal supporting member (longitudinal
chassis frame beam).
MANUFACTURED HOME
A structure, transportable in one or more sections, which
is built on a permanent chassis and is designed for use with or without
a permanent foundation when connected to the required utilities. The
term "manufactured home" does not include a recreational vehicle.
MARKET VALUE
The price at which a property will change hands between a
willing buyer and a willing seller, neither party being under compulsion
to buy or sell and both having reasonable knowledge of relevant facts.
For these regulations, a building's market value is determined by
a licensed real estate appraiser or the building's (improvement's)
most recent, full phased-in assessment value determined by the Maryland
Department of Assessments and Taxation.
MARYLAND DEPARTMENT OF THE ENVIRONMENT (MDE)

with, among other responsibilities, the coordination of the National
Flood Insurance Program in Maryland (NFIP State Coordinator) and the
administration of regulatory programs for development and construction
that occur within the waters of the state, including nontidal wetlands,
nontidal waters and floodplains, and state and private tidal wetlands
("tidal wetlands"). Unless otherwise specified, "MDE" refers to the
Department's Wetlands and Waterways Program.
MIXED USE
Any building or structure that is used or intended for use
for a mixture of nonresidential and residential uses.
NATIONAL FLOOD INSURANCE PROGRAM (NFIP)
The program authorized by the U.S. Congress in 42 U.S.C. §§ 4001

that agree to adopt and enforce minimum regulatory requirements for
development in areas prone to flooding (see definition of "special
flood hazard area").
[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. I)]
NEW CONSTRUCTION
Structures, including additions and improvements, and the
placement of manufactured homes, for which the start of construction
commenced on or after May 15, 1985, the initial effective date of
the Talbot County Floodplain Management Ordinance, including any subsequent
improvements, alterations, modifications, and additions to such structures.
NONRESIDENTIAL
A commercial or nonhabitational or mixed-use building or
structure that does not qualify as residential. This category includes
but is not limited to: commercial, industrial, recreational, and agricultural
buildings (including grain bins and silos), churches, schools, garages,

NONTIDAL WATERS
See "waters of the state." As used in these regulations,
"nontidal waters" refers to any stream or body of water within the
state that is subject to state regulation, including the "100-year
frequency floodplain of free-flowing waters." COMAR 26.17.01 states
that "the landward boundaries of any tidal waters shall be deemed
coterminous with the wetlands boundary maps adopted pursuant to Environment
Article, § 16-301, Annotated Code of Maryland." Therefore,
the boundary between the state's tidal and nontidal waters is the
tidal wetlands boundary.

or less when measured at the largest horizontal projection, designed
to be self-propelled or permanently towable by a light duty truck,
and designed primarily not for use as a permanent dwelling, but as
temporary living quarters for recreational, camping, travel, or seasonal
use.
SITE PLAN
A plan showing the proposed development of a lot or parcel. A site plan shows existing and proposed natural features, structures, building footprints and elevations, road rights-of-way, paved areas, access, walkways, vegetative cover, landscaping, screening, and stormwater management. There are two types of site plans, major and minor, with different submittal requirements and review processes as established in the Zoning, Subdivision and Land Development Ordinance, Chapter
190 of the Talbot County Code.
SPECIAL FLOOD HAZARD AREA (SFHA)
The land in the floodplain subject to a 1% or greater probability of flooding in a year. Special flood hazard areas are designated by the Federal Emergency Management Agency in Flood Insurance Studies and on Flood Insurance Rate Maps as Zones A, AE, AH, AO, A1-30, and A99, and Zones VE and Vl-30. The term includes areas shown on other flood maps that are identified in §
70-12, Flood Insurance Rate Map use and interpretation.
START OF CONSTRUCTION
The date the building permit was issued, provided the actual
start of construction, repair, or other improvement was within 180
days of the permit date. The actual start means either the first permanent
construction, such as placement of slab, footings, piles, or columns;
or the placement of a manufactured home on a foundation. Permanent
construction does not include land clearing, grading and filling;
installation of streets or walkways; excavation; the erection of temporary
forms; or installation of accessory structures, such as garages or
sheds not occupied as dwelling units or not part of the main structure.
For substantial improvements, the 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.
STRUCTURALLY CONNECTED
Method of joining the individual members of a structure to
form a complete assembly. Connections are used to ensure the reliability
of the structure, and also used to join separate structures in order
to provide rigidity, spatial distribution of structures, and construction
of reinforced building units. Connections furnish supporting reactions
and transfer loads from one member to another and may consist of fasteners,
rivets, bolts, or welded plates.
STRUCTURE
That which is built or constructed; specifically, a walled
and roofed building. This term includes gas or liquid storage tanks
that are principally above ground, as well as manufactured homes.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a structure whereby the
cost of restoring the structure to its before-damaged condition would
equal or exceed 50% of the structure's market value before the damage
occurred. Also used as "substantially damaged" structures.
SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition, or other improvement
of a structure, the cost of which equals or exceeds 50% of the structure's
market value before the improvement's start of construction. The term
includes any repair or reconstruction of structures which have incurred
substantial damage, regardless of the actual cost of the repair work
performed. The term does not, however, include either:
A.
Any project for improvement of a structure to correct existing
violations of state or local health, sanitary, or safety code specifications
which have been identified by the local code enforcement official
prior to submission of an application for a permit and which are the
minimum necessary to assure safe living conditions; or
B.
Any alteration of an historic structure, provided that the alteration
will not preclude the structure's continued designation as an historic
structure.
TEMPORARY STRUCTURE
A structure installed, used, or erected for a period of less
than 180 days.
VARIANCE
A grant of relief from the strict application of one or more
requirements of these regulations.
VIOLATION
Any construction or development in a special flood hazard
area that is being performed without an issued permit. The failure
of development for which a permit is issued to comply with these regulations
and the conditions of the issued permit. Development without the required
design certifications, the elevation certificate, or other evidence
of compliance required is presumed to be a violation until such time
as the required documentation is provided.
WATERCOURSE
The channel, including channel banks and bed, of nontidal
waters.
WATERCOURSE ALTERATION
Includes, but is not limited to widening, deepening or relocating
the channel, including excavation or filling of the channel. Watercourse
alteration does not include construction of a road, bridge, culvert,
dam, or in-stream pond unless the channel is proposed to be realigned
or relocated as part of such construction.
