BASE FLOODmeans the flood having a 1% chance of being equaled or exceeded in any given year.
COASTAL HIGH HAZARD AREAmeans an area of special flood hazard extending from offshore to the inland limit of a primary frontal dune along an open coast and any other area subject to high velocity wave action from storms or seismic sources. The area is designated on a FIRM as Zone V, V1-30, VE.
DEVELOPMENTmeans any man-made change to improved or unimproved real estate, including but not limited to building or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations or storage of equipment or materials. [US Code of Federal Regulations, Title 44, Part 59]
FLOOD INSURANCE RATE MAP (FIRM)means an official map of a community on which FEMA has delineated both the areas of special flood hazard and the risk premium zones applicable to the community.
FLOOD INSURANCE STUDY (FIS)means an examination, evaluation and determination of flood hazards, and if appropriate, corresponding water surface elevations or an examination, evaluation and determination of flood-related erosion hazards.
FLOODWAYmeans the channel of the river, creek or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. [International Building Code, Chapter 2, Section 202]
FUNCTIONALLY DEPENDENT USEmeans 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. [US Code of Federal Regulations, Title 44, Part 59] Also [Referenced Standard ASCE 24-14]
HIGHEST ADJACENT GRADEmeans the highest natural elevation of the ground surface prior to construction next to the proposed walls of a structure. [US Code of Federal Regulations, Title 44, Part 59]
HISTORIC STRUCTUREmeans any structure that is:
(1) Listed individually in the National Register of Historic Places (a listing maintained by the Department of the 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) Preservation programs which have been approved by the Secretary of the Interior; or) Individually listed on a state inventory of historic places in states with historic
(4) Individually listed on a local inventory of historic places in communities with historic preservation programs that have been certified either:
(a) By an approved state program as determined by the Secretary of the Interior or
(b) Directly by the Secretary of the Interior in states without approved programs. [US Code of Federal Regulations, Title 44, Part 59]
NEW CONSTRUCTIONmeans structures for which the start of construction commenced on or after the effective date of the first floodplain management code, regulation, ordinance, or standard adopted by the authority having jurisdiction, including any subsequent improvements to such structures. New construction includes work determined to be substantial improvement. [Referenced Standard ASCE 24-14]
RECREATIONAL VEHICLEmeans a vehicle which is:
(1) Built on a single chassis;
(2) 400 square feet or less when measured at the largest horizontal projection;
(3) Designed to be self-propelled or permanently towable by a light duty truck; and
(4) Designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use. [US Code of Federal Regulations, Title 44, Part 59]
SPECIAL FLOOD HAZARD AREAmeans the land area subject to flood hazards and shown on a Flood Insurance Rate Map or other flood hazard map as Zone A, AE, A1-30, A99, AR, AO, AH, V, VO, VE or V1-30. [Base Code, Chapter 2, Section 202]
START OF CONSTRUCTIONmeans the date of issuance for new construction and substantial improvements to existing structures, provided the actual start of construction, repair, reconstruction, rehabilitation, addition, placement or other improvement is within 180 days after the date of issuance. The actual start of construction means the first placement of permanent construction of a building (including a manufactured home) on a site, such as the pouring of a slab or footings, installation of pilings or construction of columns. Permanent construction does not include land preparation (such as clearing, excavation, grading or filling), the installation of streets or walkways, excavation for a basement, footings, piers or foundations, the erection of temporary forms or the installation of accessory buildings such as garages or sheds not occupied as dwelling units or not part of the main building. For a substantial improvement, 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. [Base Code, Chapter 2, Section 202]
STRUCTUREmeans, for floodplain management purposes, a walled and roofed building, including a gas or liquid storage tank that is principally above ground, as well as a building, other than a gas or liquid storage tank that is principally above ground and affixed to a permanent site, as well as a manufactured home on foundation. For the latter purpose, the term includes a building while in the course of construction, alteration or repair, but does not include building materials or supplies intended for use in such construction alteration or repair, unless such materials or supplies are within an enclosed building on the premises.
SUBSTANTIAL DAMAGEmeans 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 market value of the structure before the damage occurred.
SUBSTANTIAL IMPROVEMENTmeans any repair, reconstruction, rehabilitation, addition or improvement of a building or structure, the cost of which equals or exceeds 50% of the market value of the structure before the improvement or repair is started. If the structure has sustained substantial damage, any repairs are considered substantial improvement regardless of the actual repair work performed. The term does not, however, include either:
(1) Any project for improvement of a building required to correct existing health, sanitary or safety code violations identified by the Building Commissioner and that are the minimum necessary to assure safe living conditions.
(2) Any alteration of a historic structure provided that the alteration will not preclude the structure's continued designation as a historic structure. [Base Code Section 1612.2]
SUBSTANTIAL REPAIR OF A FOUNDATIONmeans when work to repair or replace a foundation results in the repair or replacement of a portion of the foundation with a perimeter along the base of the foundation that equals or exceeds 50% of the perimeter of the base of the foundation measured in linear feet, or repair or replacement of 50% of the piles, columns or piers of a pile, column or pier supported foundation, the Building Commissioner shall determine it to be substantial repair of a foundation. Applications determined by the Building Commissioner to constitute substantial repair of a foundation shall require all existing portions of the entire building or structure to meet the requirements of 780 CMR. [As amended by MA in 9th Edition BC]
VARIANCEmeans a grant of relief by a community from the terms of a flood plain management regulation. [US Code of Federal Regulations, Title 44, Part 59]
A variance from this FP Bylaw must meet the requirements set out by State law and (1) may only be granted if a good and sufficient cause and exceptional non-financial hardship exist; 2) the variance will not result in additional threats to public safety, extraordinary public expense, or fraud or victimization of the public; and 3) the variance is the minimum action necessary to afford relief. |
VIOLATIONmeans the failure of a structure or other development to be fully compliant with the community's flood plain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in § 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. [US Code of Federal Regulations, Title 44, Part 59]
ZONE AEmeans area of special flood hazard with water surface elevations determined.
ZONE AOmeans area of special flood hazards having shallow water depths and/or unpredictable flow paths between one and three ft. (Velocity flow may be evident; such flooding is characterized by ponding or sheet flow.)
ZONE VEmeans area of special flood hazards, with water surface elevations determined and with velocity, that is inundated by tidal floods (coastal high hazard area).
