Natural Hazards Mitigation PlanCity of Glendale, CaliforniaAppendix E – GlossaryBuilding codeCode officialCommunity RatingSystem (CRS)Computer-AidedDesign And Drafting(CADD)ContourCoseismic ruptureCritical facilityDebrisDebris impact loadsDebris flowDebris lineDeformationDesign floodDigitizeRegulations adopted by local governments that establish standards forconstruction, modification, and repair of buildings and otherstructures.Officer or other designated authority charged with the administrationand enforcement of the code, or a duly authorized representative, suchas a building, zoning, planning, or floodplain management official.An NFIP program that provides incentives for NFIP communities tocomplete activities that reduce flood hazard risk. When thecommunity completes specified activities, the insurance premiums ofpolicyholders in these communities are reduced.A computerized system enabling quick and accurate electronic 2-Dand 3-D drawings, topographic mapping, site plans, and profile/crosssectiondrawings.A line of equal ground elevation on a topographic (contour) map.Ground rupture occurring during an earthquake but not necessarilyon the causative fault.Facilities that are critical to the health and welfare of the populationand that are especially important following hazard events. Criticalfacilities include, but are not limited to, shelters, police and firestations, and hospitals.(Seismic) The scattered remains of something broken or destroyed;ruins; rubble; fragments. (Flooding, Coastal) Solid objects or massescarried by or floating on the surface of moving water.Debris ––Loads imposed on a structure by the impact of floodborne debris.These loads are often sudden and large. Though difficult to predict,debris impact loads must be considered when structures are designedand constructed. See Loads.A saturated, rapidly moving saturated earth flow with 50 percent rockfragments coarser than 2 mm in size which can occur on natural andgraded slopes.Line left on a structure or on the ground by the deposition of debris. Adebris line often indicates the height or inland extent reached by floodwaters.A general term for the process of folding, faulting, shearing,compression, or extension of rocks.The greater of either (1) the base flood or (2) the flood associated withthe flood hazard area depicted on a community’s flood hazard map, orotherwise legally designated.To convert electronically points, lines, and area boundaries shown onmaps into x, y coordinates (e.g., latitude and longitude, universaltransverse mercator (UTM), or table coordinates) for use in computerapplications.2006 PAGE E - 2
Natural Hazards Mitigation PlanCity of Glendale, CaliforniaAppendix E – GlossaryDisplacement timeDurationEarth flowEarthquakeEngineeringgeologistEpicenterErosionErosion hazard areaEssential facilityExpansive soilExtentExtratropicalcycloneThe average time (in days) which the building's occupants typicallymust operate from a temporary location while repairs are made to theoriginal building due to damages resulting from a hazard event.How long a hazard event lasts.Imperceptibly slow-moving surficial material in which 80 percent ormore of the fragments are smaller than 2 mm, including a range ofrock and mineral fragments.Vibratory motion propagating within the Earth or along its surfacecaused by the abrupt release of strain from elastically deformed rockby displacement along a fault.A geologist who is certified by the State as qualified to apply geologicdata, principles, and interpretation to naturally occurring earthmaterials so that geologic factors affecting planning, design,construction, and maintenance of civil engineering works are properlyrecognized and used. An engineering geologist is particularly neededto conduct investigations, often with geotechnical engineers, of siteswith potential ground failure hazards.The point at the Earth's surface directly above where an earthquakeoriginated.Under the National Flood Insurance Program, the process of thegradual wearing away of landmasses. In general, erosion involves thedetachment and movement of soil and rock fragments, during a floodor storm or over a period of years, through the action of wind, water,or other geologic processes.Area anticipated to be lost to shoreline retreat over a given period oftime. The projected inland extent of the area is measured bymultiplying the average annual long-term recession rate by thenumber of years desired.Elements that are important to ensure a full recovery of a communityor state following a hazard event. These would include: governmentfunctions, major employers, banks, schools, and certain commercialestablishments, such as grocery stores, hardware stores, and gasstations.A soil that contains clay minerals that take in water and expand. If asoil contains sufficient amount of these clay minerals, the volume ofthe soil can change significantly with changes in moisture, withresultant structural damage to structures founded on these materials.The size of an area affected by a hazard or hazard event.Cyclonic storm events like Nor'easters and severe winter low-pressuresystems. Both West and East coasts can experience these non-tropicalstorms that produce gale-force winds and precipitation in the form ofheavy rain or snow. These cyclonic storms, commonly calledNor'easters on the East Coast because of the direction of the stormwinds, can last for several days and can be very large – 1,000-milewide storms are not uncommon.2006 PAGE E - 3
