Certain areas of Baltimore City are subject to periodic inundation that results in loss of life and property, risks to health and safety, disruption of commerce and governmental services, and extraordinary public expenditures for flood protection and relief.
Flood losses and associated losses are created by structures inappropriately located, inadequately elevated, or otherwise unprotected and vulnerable to floods or erosion or by development that increases flood or erosion damage to other lands or development.
The biological values of floodplains, particularly tidal and non-tidal wetlands, can be adversely affected by floodplain development.
Baltimore City has the responsibility under the Flood Hazard Management Act of 1976, Title 5, Subtitle 8 of the State Environment Article, to control floodplain development in order to protect persons and property from danger and destruction and to preserve the biological values and environmental quality of the watersheds or the portions of watersheds under its jurisdiction.
Baltimore City has the responsibility under the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973 to adopt and enforce floodplain management regulations that, at a minimum, meet the requirements of 44 Code of Federal Regulations Parts 55-77 et seq., in order to participate in the National Flood Insurance Program and remain eligible for federally subsidized flood insurance, federal disaster relief, and Federal and State financial assistance.
Baltimore City contains densely developed tidal shorelines that are and will continue to be in high demand. The science behind climate change acknowledges that sea-level rise and coastal flooding will impact current and future development along the shoreline. Floodplain regulations are meant to protect people and property while making the City more resilient to the impacts from natural disasters and climate change.
It is, therefore, the intent of the Mayor and City Council by this Division I:to protect human life and health;
to minimize public and private property damage;
to encourage the utilization of appropriate construction practices in order to prevent or minimize flood damage in the future;
to protect individuals from unwittingly buying lands and structures that are unsuited for intended purposes because of the flood hazards;
to protect water supply, sanitary sewage disposal, and natural drainage;
to reduce financial burdens imposed on the community, its governmental units, and its residents by preventing the unwise design and construction of development in areas subject to flooding;
to provide for public awareness of the flooding potential; and
to provide for the biological and environmental quality of the watersheds or the portions of watershed located in Baltimore City.
This Division I provides a unified comprehensive approach to floodplain management that addresses the requirements of the following Federal and State programs concerned with floodplain management:the National Flood Insurance Program and the President’s Executive Order 11988 of May 27, 1977, on floodplain management;
the State Waterway Construction Permit Program;
the State Wetlands Permit Program;
the U.S. Army Corps of Engineers’ Section 10 and Section 404 Permit Programs; and
the State Coastal Zone Management Program.
The degree of flood protection required by these regulations 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 regulations do not imply that land outside of the special flood hazard areas or uses that are permitted within those areas will be free from flooding or flood damage.
These regulations shall not create liability on the part of the City of Baltimore, any of its officers or employees, the Maryland Department of the Environment (MDE), or the Federal Emergency Management Agency (FEMA) for any flood damage that results from reliance on these regulations or any administrative decision lawfully made hereunder.

The City must establish a Floodplain District and an official floodplain map to include all areas subject to inundation by floodwaters.
The bases of this delineation must be, at a minimum, the data contained in the most recent Flood Insurance Study for Baltimore City, and illustrated in the Flood Insurance Rate Map. The Flood Insurance Rate Map illustrates both the most recently adopted Special Flood Hazard Areas and the Flood Resilience Area.
The base-flood elevation, as determined in the Flood Insurance Study, is graphically delineated on the official floodplain map.
Where field-surveyed topography or digital topography indicates that ground elevations are above the base-flood elevation in a Special Flood Hazard Area, then the area is considered in the Special Flood Hazard Area until FEMA issues a Letter of Map Change.
Where field-surveyed topography or digital topography indicates that ground elevations are below the closest applicable flood-protection elevation, even in areas not delineated on the FIRM as a Regulated Flood Hazard Area, the area is considered to be a Regulated Flood Hazard Area.
The Floodplain District is an overlay on any zoning district, as provided in the Zoning Code of Baltimore City.

The Floodplain District comprises the subdistricts set forth in this section.
In all floodplain districts, the flood-protection elevation is calculated as follows:In the tidal floodplain areas, it is the height and geographic extent of the 0.2% annual chance flood in the tidal area plus freeboard.
In the non-tidal floodplain areas, it is the extent of the 0.2% annual chance flood, and the height of the 1% annual chance flood plus freeboard.
The Floodway is that part of the Floodplain District that is reserved to convey a base-flood discharge so that the cumulative increase in the water surface elevation of the base-flood discharge is no more than the height designated by FEMA in the Flood Insurance Study.
The Floodway Fringe comprises those lands within the Floodplain District that:are subject to inundation by a base flood; and
lie beyond the Floodway (where a floodway has been determined), or in areas where detailed study data, profiles, and base-flood elevations have been established.
The Floodway Fringe appears on the Flood Insurance Rate Map as Zone AE.
The Approximated Floodplain comprises those lands within the Floodplain District that:are subject to inundation by a base flood; and
lie in:areas for which a detailed study has not been performed, but a base floodplain boundary has been approximated; or
areas that are subject to shallow flooding.
A base-flood elevation must be established after consideration of any flood elevation and floodway data available from Federal, State, or other sources.
The Approximated Floodplain appears on the Flood Insurance Rate Map as Zones A and AO.
The Coastal Floodplain, also referred to as tidal floodplain, comprises those lands within the Floodplain District that:due to high tides, hurricanes, tropical storms, and steady onshore winds, are subject to coastal or tidal inundation by a base flood; and
lie in areas where detailed study data are available.
The Coastal Floodplain appears on the Flood Insurance Rate Map as Zones A and AE, and includes areas encompassed by transects delineated by FEMA in the Flood Insurance Study. (In Zone AE, a designation on the FIRM indicating “Limit of Moderate Wave Action” refers to the landward limit of waves of 1.5 feet or more in height.)
The Coastal High Hazard Area is the area within a special flood hazard area extending from offshore to the inland limit of a primary frontal dune along an open coast and any other area that is subject to high velocity wave action from storms or seismic sources. This area is designated on FIRMs as velocity zones V, VO, VE, or V1-30, and includes areas encompassed by transects delineated by FEMA in the Flood Insurance Study.
The Coastal High Hazard Area appears on the Flood Insurance Rate Map as Zones V and VE.

Regulated Flood Hazard Areas in the nontidal floodplain are designated on the FIRM as “Special Flood Hazard Areas”.
The flood elevations for these areas correspond to the base-flood elevations specified in the Flood Insurance Study.
Regulated Flood Hazard Areas in the tidal floodplain are designated on the FIRM as Zones AE, V, VE, and X.
The flood elevations for Zones V and VE are as shown in the Flood Insurance Study’s Table 4 {“Transect Data”}, under the column heading “Zone Designation and BFE”.
The flood elevations for Shaded Zone X (“areas of 0.2% annual chance flood”) and for Zones A and AE are those shown in the Flood Insurance Study’s Table 4 {“Transect Data”}, under the column heading “0.2% Annual Chance”.
To establish flood elevations for Regulated Flood Hazard Areas that do not have these elevations shown on the Flood Insurance Rate Map or in the Flood Insurance Study, the Floodplain Manager may:provide the best available data for flood elevations;
require the applicant to obtain available information from Federal, State, or other sources; or

This section applies to any property owner requesting mapping changes.
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.
A Letter of Map Amendment is 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.
A Letter of Map Revision is 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.
A Conditional Letter of Map Revision is a formal review and comment as to whether a proposed flood protection project or other project comply 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; on submission and approval of certified as-built documentation, a Letter of Map Revision may be issued by FEMA, to revise the effective FIRM.
If a proposed development is contingent upon a map change, no permits will be issued for the development until the Letter of Map Revision (LOMR) has been issued by FEMA.

If the proposal involves more than 5 lots or more than 5 acres and the base-flood elevation has not been determined for the land area, the developer must determine the base-flood elevation and delineate that flood elevation on the plan. If hydrologic and hydraulic engineering analyses are submitted, they must be certified in accordance with the requirements of the Maryland Department of the Environment and the Federal Emergency Management Agency.
All plans must be certified by a licensed professional engineer or professional architect and reviewed by the Department of General Services to assure that:all proposals are consistent with the need to minimize flood damage;
all necessary permits have been received from the State Water & Science Administration and appropriate Federal agencies;
all public and private utilities and facilities (including sewer, water, telephone, electric, gas, etc.) are located, constructed, and floodproofed to minimize or eliminate flood damage;
adequate drainage is provided to reduce exposure to flood hazards;
during a base flood, at least 1 access point provides safe vehicular access to and egress from the subdivision or new development; and
adequate measures have been taken to minimize adverse environmental impacts of the proposed development.
