Sec. 6-300 FLOODPLAIN DISTRICT 6-301 Purpose and Intent (A) This ordinance is adopted pursuant to the authority granted to all localities by Va. Code §

15.2 – 2280, as well as the authority specifically granted to the City in its Charter. The purpose of these provisions is to prevent: the loss of life and property, the creation of health and safety hazards, the disruption of commerce and governmental services, the extraordinary and unnecessary expenditure of public funds for flood protection and relief, and the impairment of the tax base by: (1) regulating uses, activities, and development which, alone or in combination with other

existing or future uses, activities, and development, will cause unacceptable increases in flood heights, velocities, and frequencies;

(2) restricting or prohibiting certain uses, activities, and development from locating within districts subject to flooding;

(3) requiring all those uses, activities, and developments that do occur in flood-prone districts to be protected and/or flood-proofed against flooding and flood damage; and,

(4) protecting individuals from buying land and structures which are unsuited for intended purposes because of flood hazards.

6-302 Applicability (A) These provisions shall apply to all privately and publicly owned lands within the jurisdiction

of the City of Alexandria and identified as being in a floodplain as designated in the Flood Insurance Study and as shown on the Flood Insurance Rate Maps prepared by the Federal Emergency Management Agency (FEMA) dated June 16, 2011.

(B) The floodplain district regulations in Section 6-300 are adopted in compliance with floodplain management criteria set forth in regulations promulgated by FEMA.

(C) This section shall be applicable to all applicants for building permits in the floodplain area. (D) All buildings for which a building permit shall have been duly and regularly issued by the

director of building and mechanical inspections on or before May 24, 1977, which permit has not expired, may be completed without the necessity of complying with the floodplain district regulations in Section 6-300, but after completion, any such building or structure and the land on which it is situated shall be subject to all the provisions of said section.

(E) All preliminary site plans which have been duly and regularly approved on or before May 24, 1977, and which have not expired, may be completed without the necessity of complying with the floodplain district regulations in Section 6-300, but after completion, any building or structure on said site plan together with the land included in said site plan shall be subject to all the provisions of said section.

(F) All final site plans which have been duly and regularly approved and released on or before May 24, 1977, and which have not expired may be completed without the necessity of complying with the floodplain district regulations in Section 6-300, but after completion, any building or structure on said site plan together with the land included in said site plan shall be subject to all the provisions of said section.

(G) Any building or structure which is in existence on or before June 15, 2011, or for which a preliminary or combination site plan, building permit or subdivision approved on or before June 15, 2011, continues in force and effect shall not be deemed a nonconforming use provided, that any such building or structure which, following June 15, 2011, is the subject of substantial improvement shall comply with the floodplain regulations in effect at the time of such improvement.

Should any uncertainty occur with respect to the definition of any word, term or phrase used in this section, the applicable definitions set out in 44 CFR 59.1, as amended, shall apply. (A) A Zone. An area of the one hundred (100)-year flood as shown on the Flood Insurance

Rate Map. This zone is also referred to as the Approximated Floodplain District. (B) AE Zone. An area shown of the 100-year flood on the Flood Insurance Rate Map for which

corresponding base flood elevations have been provided. This zone is also referred to as the Special Floodplain District.

(C) Base flood. The flood having a one percent chance of being equaled or exceeded in any given year. May also be referred to as the 100-year flood.

(D) Base flood elevation (BFE). The FEMA designated 100-year water surface elevation as shown on the Flood Insurance Rate Map that corresponds to the base flood.

(E) Basement. Any area of a building (including parking) having its floor subgrade (below ground level) on all sides.

(F) Development. Any man-made change to improved or unimproved real estate, including, but not limited to, the construction of buildings or other structures, the placement of manufactured homes, the construction of streets, the installation of utilities and other activities or operations involving paving, filling, grading, excavating, mining, dredging or drilling, the storage of equipment or materials.

(G) 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 (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.

(H) Flood/flooding. (1) A general and temporary condition of partial or complete inundation of normally dry land

areas from: (a) the overflow of inland or tidal waters; or, (b) the unusual and rapid accumulation or runoff of surface waters from any source. (c) mudflows which are proximately caused by flooding as defined in paragraph (1)(b) of

this definition and are akin to a river of liquid and flowing mud on the surfaces of normally dry land areas, as when earth is carried by a current of water and deposited along the path of the current.

(2) The collapse or subsistence of land along the shore of a lake or other body of water as a result of erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly caused by an unusually high water level in a natural body of water, accompanied by a severe storm, or by an unanticipated force of nature such as flash flood or an abnormal tidal surge, or by some similarly unusual and unforeseeable event which results in flooding as defined in paragraph (1)(a) of this definition.

(I) Flood Insurance Rate Map (FIRM). An official map of a community, on which the FEMA Federal Insurance Administrator has delineated both the special flood hazard areas and the risk premium zones applicable to the community. A Flood Insurance Rate Map that has been made available digitally is called a Digital Flood Insurance Rate Map (DFIRM).

(P) Freeboard. A factor of safety usually expressed in feet above a specified flood level for purposes of floodplain management. “Freeboard” tends to compensate for the many unknown factors that could contribute to flood heights greater than the height calculated for a selected size flood and floodway conditions, such as wave action, bridge openings, and the hydrological effect of urbanization in the watershed.

(Q) Highest adjacent grade. The highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure.

(R) Historic structure. Any structure that is: (1) listed individually in the National Register of Historic Places (a listing maintained by the

Department of Interior) or preliminarily determined by the Secretary of the Interior as meeting the requirements for individual listing on the National Register;

(2) certified or preliminarily determined by the Secretary of the Interior as contributing to the historical significance of a registered historic district or a district preliminarily determined by the Secretary to qualify as a registered historic district;

(3) individually listed on a state inventory of historic places in states with historic preservation programs which have been approved by the Secretary of the Interior; or,

(4) individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified either by an approved state program as determined by the Secretary of the Interior or directly by the Secretary of the Interior in states without approved programs.

(S) Lowest floor. The lowest floor of the lowest enclosed area (including basement). A parking structure that is below grade on all sides is considered a basement and therefore the lowest floor. An unfinished or flood resistant enclosure, usable solely for parking of vehicles, building access or storage, in an area other than a basement area (the enclosure is not below grade on all sides) is not considered a building's lowest floor; provided, that such enclosure is not built so as to render the structure in violation of the applicable floodproofing non-elevation design requirements of this Section 6-300.

(AA) Special Flood Hazard Area (SFHA). The land in the floodplain subject to a one percent or greater chance of being flooded in any given year as designated on the official Flood Insurance Rate Map for the City of Alexandria.

(BB) Start of construction. The date a building permit is issued, provided that the actual start of construction begins within 180 days of the permit issuance date. For new construction, the actual start of construction means the initial placement of permanent construction of a structure on the site, such as the pouring of footings or a slab, the installation of piles, the construction of columns or any work beyond the state 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, or the installation of streets or walkways, or excavation for a basement or for footings, piers or foundations, or the erection of temporary forms, or the installation of accessory buildings, such as garages or sheds not occupied as dwelling units and 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 the alteration affects the external dimensions of the buildings.

(CC) Structure. For flood plain management purposes, a walled and roofed building, including a gas or liquid storage tank, that is principally above ground, as well as a manufactured home. “Structure'' for insurance coverage purposes, means: (1) A building with two or more outside rigid walls and a fully secured roof, that is affixed to a

permanent site; (2) A manufactured home (also known as a mobile home), is a structure: built on a

Page 22: DOCKET ITEM Text Amendment #2011-0004 -3-ld-1I Floodplain ...dockets.alexandriava.gov/fy11/031211ph/di5.pdf · 11101€ 104040. OIlIER FLOOD AREAS 20000 010000(0.24.01110401000000

Page 5 of 12

permanent chassis, transported to its site in one or more sections, and affixed to a permanent foundation; or

(3) A travel trailer without wheels, built on a chassis and affixed to a permanent foundation, that is regulated under the community’s floodplain management and building ordinances or laws.

For the latter purpose, “structure” does not mean a recreational vehicle or a park trailer or other similar vehicle, except as described in paragraph (3) of this definition, or a gas or liquid storage tank.

(DD) 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 percent of the market value of the building or structure before the damage occurred.

(EE) Substantial improvement. Any repair, reconstruction, rehabilitation, addition or other improvement of a building or structure, the cost of which equals or exceeds 50 percent of the market value of the building or structure immediately before construction of the improvement is commenced, or any restoration of a building or structure which has incurred substantial damage; provided, that the term does not include:

(1) Any improvement of a building or structure that is necessary to correct existing violations of state or local health, sanitary or safety code specifications which have been identified by appropriate officials of the state or city and which are the minimum necessary to assure safe living conditions; or

(2) Any improvement of a "historic structure," as defined in this section, so long as the improvement does not preclude the structure's continued designation as a "historic structure."

(FF) Violation. The failure of a structure or other development to be fully compliant with the City of Alexandria’s floodplain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in 44 CFR Sec. 60.3(b)(5), (c)(4), (c)(10), (d)(3), (e)(2), (e)(4), or (e)(5) is presumed to be in violation until such time as that documentation is provided.

6-304 Description of Floodplain Districts (A) The various floodplain districts shall include the Special Flood Hazard Areas described

below. The basis for the delineation of these districts shall be the Flood Insurance Study and the Flood Insurance Rate Maps for the City of Alexandria prepared by FEMA, Federal Insurance Administration, dated June 16, 2011, and any subsequent revisions and amendments thereto. (1) The Special Floodplain District shall include those areas identified as an AE Zone on the

Flood Insurance Rate Map for which 100-year base flood elevations have been provided.

(2) The Approximated Floodplain District shall include those areas identified as an A Zone on the Flood Insurance Rate Map. In these zones, no detailed flood profiles or elevations are provided, but the 100-year floodplain boundary has been approximated. For these areas, the 100-year flood elevations and floodway information from federal, state, and other acceptable sources shall be used, when available. Where the specific 100-year flood elevation cannot be determined for this area using other sources of data, such as the U.S. Army Corps of Engineers Flood Plain Information Reports, U.S. Geological Survey Flood-prone Quadrangles, etc., then the applicant for the proposed use, development and/or activity shall determine this elevation in accordance with FEMA-approved hydrologic and hydraulic engineering techniques. Hydrologic and

hydraulic analyses shall be undertaken only by professional engineers or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect currently-accepted technical concepts. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough review by the Director of Transportation and Environmental Services.

(B) The delineation of any of the floodplain districts may be revised by the City of Alexandria where natural or man-made changes have occurred and/or where more detailed studies have been conducted or undertaken by the U.S. Army Corps of Engineers or other qualified agency, or an individual documents the need for such change. Updates to the delineation of the floodplain districts require approval from both the City of Alexandria and the FEMA Federal Insurance Administration.

(C) Any uncertainty on the floodplain district map, or Flood Insurance Rate Map, with respect to the boundary of any floodplain district, either A or AE Zone, shall be determined by the Director of Transportation and Environmental Services by scaling and computation from the map or by land survey information.

6-305 Administration (A) The Director of Transportation and Environmental Services shall be responsible for the

administration of the floodplain management regulations set forth in this Section 6-300. He or she shall be responsible for the review of all proposed uses and development to determine whether the land on which the proposed use or development is located is in a floodplain, and that the site is reasonably safe from flooding.

(B) An applicant must apply for a permit and issuance of the permit is required prior to the start of any development within the Special Flood Hazard Area.

(C) No site plan, subdivision plat or building permit application which proposes to construct or make substantial improvements within any floodplain district shall be approved by any agency of the City of Alexandria without certification by the Director of Transportation and Environmental Services that the plan, plat or permit application meets the requirements of this Section 6-300. The Director of Transportation and Environmental Services shall insure that all other required permits related to development in the floodplain from state or federal governmental agencies have been obtained.

(D) All applications for new construction or substantial improvement within any floodplain district, and all building permits issued for the floodplain shall incorporate the following information: (1) The base flood elevation at the site. (2) The elevation of the lowest floor (including basement). (3) For structures to be floodproofed (nonresidential only), the elevation to which the structure will be floodproofed. (4) Topographic information showing existing and proposed ground elevations.

(E) The Director of Transportation and Environmental Services may require information from the applicant, including, but not limited to, an engineering study of the floodplain. Upon a determination that the land on which the proposed use or development is located in a floodplain, the Director of Transportation and Environmental Services shall determine whether such use or development may be permitted in accordance with the provisions of Section 6-306 through 6-308 or requires the approval of a variance as set forth in Section 6-311.

(F) The Director of Transportation and Environmental Services shall be responsible for the collection and maintenance of records necessary for the City’s participation in the National Flood Insurance Program. Base flood elevations may increase or decrease resulting from physical changes affecting flooding conditions. As soon as practicable, but not later than six

months after the date such information becomes available, the Director of Transportation and Environmental Services shall notify or require the applicant to notify the FEMA Federal Insurance Administrator of any change in base flood elevation or the boundaries of any Special Flood Hazard Area depicted on the City’s Flood Insurance Rate Map by submitting technical and scientific data to FEMA for a Letter of Map Revision.

6-306 Special Regulations Within the boundaries of any A or AE Zones in any floodplain district as shown on the Flood Insurance Rate Map, buildings or structures and their extensions and accessory buildings or structures maybe be constructed or substantially improved only in accordance with the following requirements of this Section 6-300 and all other applicable provisions of law. (A) The elevation of the lowest floor, including the basement, for any new residential building or

any extension to a residential building shall be at least one foot above the base flood elevation.

(B) The elevation of the lowest floor, including the basement for any new nonresidential building or structure and any extension or accessory to a nonresidential building shall be at least one foot above the base flood elevation. Nonresidential buildings located in all A or AE zones may be floodproofed in lieu of being elevated provided that all areas of the building components below the elevation corresponding to the base flood elevation plus one foot are watertight with walls substantially impermeable to the passage of water, and use structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effect of buoyancy. In no event shall any floor below at least one foot above the base flood elevation be used for human or animal habitation, food storage or food preparation.

(C) All new and replacement public utilities, water mains and sanitary sewers shall be designed to minimize or eliminate infiltration and exfiltration and to insure their structural integrity under flood conditions to the satisfaction of the Director of Transportation and Environmental Services.

(D) Water heaters, furnaces, electrical distribution panels and other critical mechanical or electrical installations shall not be installed below the base flood elevation. Separate electrical circuits shall serve areas below the base flood elevation and shall be dropped from above.
