A. 
Whereas:
(1) 
The Federal Emergency Management Agency has identified special flood hazard areas within the boundaries of Harford County, Maryland. Special flood hazard areas are subject to periodic inundation which may result in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare. Structures that are inadequately elevated, improperly floodproofed, or otherwise unprotected from flood damage also contribute to flood losses.
(2) 
Harford County, by resolution, agreed to meet the requirements of the National Flood Insurance Program and was accepted for participation in the Program on March 2, 1983. As of that date, or as of March 2, 1983 the initial effective date of the Harford County Flood Insurance Rate Map, all development and new construction as defined herein are to be compliant with this chapter.
(3) 
The Maryland General Assembly, in MD. Code Ann., Land Use Article, Title 4, has established as policy of the state that the orderly development and use of land and structures requires comprehensive regulation through the implementation of planning and zoning control, and that planning and zoning controls shall be implemented by local government in order to, among other purposes, secure the public safety, promote health and general welfare and promote the conservation of natural resources.
B. 
It is the purpose of these provisions to promote the public health, safety and general welfare, and to:
(1) 
Protect human life, health and welfare;
(2) 
Encourage the utilization of appropriate construction practices in order to prevent or minimize flood damage in the future;
(3) 
Minimize flooding of water supply and sanitary sewage disposal systems;
(4) 
Maintain natural drainage;
(5) 
Reduce financial burdens imposed on the community, its governmental units and its residents, by discouraging unwise design and construction of development in areas subject to flooding;
(6) 
Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
(7) 
Minimize prolonged business interruptions;
(8) 
Minimize damage to public facilities and other utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges;
(9) 
Reinforce that those who build in and occupy special flood hazard areas should assume responsibility for their actions;
(10) 
Minimize the impact of development on adjacent properties within and near flood-prone areas;
(11) 
Provide that the flood storage and conveyance functions of floodplains are maintained;
(12) 
Minimize the impact of development on the natural and beneficial functions of floodplains;
(13) 
Prevent floodplain uses that are either hazardous or environmentally incompatible; and
(14) 
Meet community participation requirements of the National Flood Insurance Program as set forth in the Code of Federal Regulations (CFR) at 44 C.F.R. § 59.22.
This chapter shall apply to all special flood hazard areas within the jurisdiction of Harford County and identified in Section 131-3.
A. 
For the purposes of this chapter, the minimum basis for establishing special flood hazard areas and base flood elevations is the Flood Insurance Study for Harford County, Maryland and incorporated areas dated April 19, 2016, or the most recent revision thereof, and the accompanying Flood Insurance Rate Map(s) and all subsequent amendments and revisions to the FIRMs. The FIS and FIRMs are retained on file and available to the public at the Department of Planning and Zoning.
B. 
Where field surveyed topography or digital topography indicates that ground elevations are below the closest applicable base flood elevation, even in areas not delineated as a special flood hazard on the FIRM, the area shall be considered as a special flood hazard area.
C. 
To establish base flood elevations in special flood hazard areas that do not have such elevations shown on the FIRM, the Floodplain Administrator may provide the best available data for base flood elevations, may require the applicant to obtain available information from federal, state or other sources, or may require the applicant to establish special flood hazard areas and base flood elevations as set forth in Section 131-10, Section 131-11 and Section 131-12 of this chapter.
These provisions are not intended to repeal or abrogate any existing laws or regulations, including Subdivision Regulations, Zoning Laws, Building Codes, or any existing easements, covenants or deed restrictions. In the event of a conflict between these provisions and any other law, the more restrictive shall govern.
In the interpretation and application of this chapter, all provisions shall be:
A. 
Considered as minimum requirements;
B. 
Liberally construed in favor of the governing body; and
C. 
Deemed neither to limit nor repeal any other powers granted under state statutes.
Notes referencing publications of the Federal Emergency Management Agency refer to the most recent edition of those publications, are intended only as guidance and do not bind or alter the authority of the Floodplain Administrator to interpret and apply these provisions.
A. 
The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur, and flood heights may be increased by man-made or natural causes. These provisions do not imply that land outside of the special flood hazard areas or uses that are permitted within such areas will be free from flooding or flood damage.
B. 
These provisions shall not create liability on the part of Harford County, any agent, officer or employee thereof, the Maryland Department of the Environment (MDE) or the Federal Emergency Management Agency (FEMA), for any flood damage that results from reliance on these provisions or any administrative decision lawfully made hereunder.
Should any section or provision of this chapter be declared by the courts to be unconstitutional or invalid, such decision shall not affect the validity of the provisions as a whole, or any part thereof other than the part so declared to be unconstitutional or invalid.
Unless specifically defined below, words or phrases used in these provisions shall be interpreted to have the meaning they have in common usage and to give these provisions the most reasonable application.
ACCESSORY STRUCTURE

FIRMs that have been prepared in digital format or converted to digital format are referred to as digital FIRMs (DFIRM).
FLOOD INSURANCE STUDY (FIS)
The official report in which the Federal Emergency Management Agency has provided flood profiles, floodway information and the water surface elevations.
FLOOD OPENING
A flood opening (non-engineered) is an opening that is used to meet the prescriptive requirement of 1 square inch of net open area for every square foot of enclosed area. An engineered flood opening is an opening that is designed and certified by a licensed professional engineer or licensed architect as meeting certain performance characteristics, including providing automatic entry and exit of floodwaters; this certification requirement may be satisfied by an individual certification for a specific structure or issuance of an evaluation report by the ICC Evaluation Service, Inc. (NOTE: See NFIP Technical Bulletin #1, "Openings in Foundation Walls and Walls of Enclosures.")
FLOOD or FLOODING
A general and temporary condition of partial or complete inundation of normally dry land areas from:
A. 
The overflow of inland or tidal waters, and/or
B. 
The unusual and rapid accumulation or runoff of surface waters from any source.
FLOOD PROTECTION ELEVATION
The base flood elevation plus 2 feet of freeboard. Freeboard is a factor of safety that compensates for uncertainty in factors that could contribute to flood heights greater than the height calculated for a selected size flood and floodway conditions, such as wave action, obstructed bridge openings, debris and ice jams, climate change and the hydrologic effect of urbanization in a watershed.
FLOOD PROTECTION SETBACK
A distance measured perpendicular to the top of bank of a watercourse that delineates an area to be left undisturbed to minimize future flood damage and to recognize the potential for bank erosion. Along nontidal waters of the state, the flood protection setback is:
A. 
100 feet, if the watercourse has special flood hazard areas shown on the FIRM, except where the setback extends beyond the boundary of the flood hazard area; or
B. 
50 feet, if the watercourse does not have special flood hazard areas shown on the FIRM.
FLOOD ZONE

B. 
Zone AE and Zone A1-30: special flood hazard areas subject to inundation by the 1-percent annual chance (100-year) flood; base flood elevations are determined; floodways may or may not be determined. In areas subject to tidal flooding, the limit of moderate wave action may or may not be delineated.
C. 
Zone AH and Zone AO: areas of shallow flooding, with flood depths of 1 to 3 feet (usually areas of ponding or sheet flow on sloping terrain), with or without BFEs or designated flood depths.
D. 
Zone B and Zone X (shaded): areas subject to inundation by the 0.2-percent annual chance (500-year) flood; areas subject to the 1-percent annual chance (100-year) flood with average depths of less than 1 foot or with contributing drainage area less than 1 square mile; and areas protected from the base flood by levees.

FLOODPROOFING CERTIFICATE
FEMA form that is to be completed, signed and sealed by a licensed professional engineer or licensed architect to certify that the design of floodproofing and proposed methods of construction are in accordance with the applicable requirements of Section 131-32B of these provisions. (NOTE: FEMA Form 086-0-34 is available online at http://www.fema.gov/library/viewrecord.do?id=1600.)
FLOODPROOFING OR FLOODPROOFED
Any combination of structural and nonstructural additions, changes or adjustments to buildings or structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitary facilities, structures and their contents, such that the buildings or structures are watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy. (NOTE: State regulations at COMAR 26.17.04.11(B)(7) do not allow new nonresidential buildings in nontidal waters of the state to be floodproofed.)
FLOODWAY
The channel of a river or other watercourse and the adjacent land areas that must be reserved in order to pass the base flood discharge such that the cumulative increase in the water surface elevation of the base flood discharge is no more than a designated height. When shown on a FIRM, the floodway is referred to as the "designated floodway."
FREE-OF-OBSTRUCTION
A term that describes open foundations (pilings, columns or piers) without attached elements or foundation components that would obstruct the free passage of floodwaters and waves beneath structures that are elevated on such foundations. (NOTE: See NFIP Technical Bulletin #5, "Free-of-Obstruction Requirements.")
FUNCTIONALLY DEPENDENT USE
A use which cannot perform its intended purpose unless it is located or carried out in close proximity to water; the term includes only docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers and ship building and ship repair facilities, but does not include long-term storage or related manufacturing facilities.

LETTER OF MAP CHANGE (LOMC)
A Letter of Map Change is an official FEMA determination, by letter, that amends or revises 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 NFIP 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 FEMA to revise the effective FIRM.
LICENSED
As used in these regulations, licensed refers to professionals who are 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.
LIMIT OF MODERATE WAVE ACTION (LIMWA)

LOWEST FLOOR
The lowest floor of the lowest enclosed area (including basement) of a building or 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 the purposes of these regulations, the market value of a building is determined by a licensed real estate appraiser or the most recent, full phased-in assessment value of the building (improvement) determined by the Maryland Department of Assessments and Taxation.
MARYLAND DEPARTMENT OF THE ENVIRONMENT (MDE)
A principal department of the State of Maryland that is charged 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 STRUCTURE
Any structure that is used or intended for use for a mixture of nonresidential and residential uses in the same structure.
NATIONAL FLOOD INSURANCE PROGRAM (NFIP)
The program authorized by the U.S. Congress in 42 U.S.C. §§ 4001-4129. The NFIP makes flood insurance coverage available in communities that agree to adopt and enforce minimum regulatory requirements for development in areas prone to flooding (see definition of "special flood hazard area").
NEW CONSTRUCTION
Structures, including additions and improvements, and the placement of manufactured homes, for which the start of construction commenced on or after March 2, 1983, the initial effective date of the Harford County Flood Insurance Rate Map, including any subsequent improvements, alterations, modifications and additions to such structures.
NFIP STATE COORDINATOR
See Maryland Department of the Environment.
NONTIDAL WATERS OF THE STATE
See "waters of the state." As used in these regulations, "nontidal waters of the state" 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 26.17.04 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 tidal and nontidal waters of the state is the tidal wetlands boundary.
PERSON
An individual or group of individuals, corporation, partnership, association or any other entity, including state and local governments and agencies.
RECREATIONAL VEHICLE
A vehicle that is built on a single chassis, 400 square feet 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.
REPETITIVE LOSS
A building covered by a contract for flood insurance that has incurred a flood-related damage on 2 separate occasions during a 10-year period ending on the date of the event for which a second claim is made, in which the cost of repairing the flood damage on the average equals or exceeded 25% of the market value of the building at the time of each such flood event.
SPECIAL FLOOD HAZARD AREA (SFHA)
The land in the floodplain subject to a one-percent or greater chance of flooding in any given 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 V1-30. The term includes areas shown on other flood maps that are identified in Section 131-3.
START OF CONSTRUCTION
The date the building permit was issued, 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 the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers or foundations or the erection of temporary forms; nor does it include the installation on the property 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.
STRUCTURE
That which is built or constructed; specifically, a walled and roofed building, including a gas or liquid storage tank that is principally above ground, as well as a manufactured home.
SUBSTANTIAL DAMAGE
Damage of any origin sustained by a building or structure whereby the cost of restoring the building or structure to its before damaged condition would equal or exceed 50% of the market value of the building or structure before the damage occurred. Also used as "substantially damaged" structures. [NOTE: See "Substantial Improvement/Substantial Damage Desk Reference" (FEMA P-758).]
SUBSTANTIAL IMPROVEMENT
Any reconstruction, rehabilitation, addition or other improvement of a building or structure, over a 5 year period, the cumulative cost of which equals or exceeds 50% of the market value of the building or structure before the start of construction of the improvement. The term includes structures which have incurred repetitive loss or substantial damage, regardless of the actual repair work performed. The term does not, however, include either:
A. 
Any project for improvement of a building or 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 a historic structure, provided that the alteration will not preclude the structure's continued designation as a historic structure.
[NOTE: See "Substantial Improvement/Substantial Damage Desk Reference" (FEMA P-758).]
TEMPORARY STRUCTURE
A structure installed, used or erected for a period of less than 180 days.
UTILITIES
A public or private service owned and operated for the benefit of the public, including but not limited to, gas lines, electrical and telephone systems, sewer and water lines, sewage pumping stations, electrical transmission lines and interstate pipelines.

VIOLATION
Any construction or development in a special flood hazard area that is being performed without an issued permit. The failure of a building, structure or other development for which a permit is issued to be fully compliant with these provisions and the conditions of the issued permit. A building, structure or other 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 of the state.
WATERS OF THE STATE
(See Environment Article, Title 5, Subtitle 1, Annotated Code of Maryland.) Waters of the state include:
A. 
Both surface and underground waters within the boundaries of the state subject to its jurisdiction;
B. 
That portion of the Atlantic Ocean within the boundaries of the state;
