Areas such as garages are not considered livable space. The term "private garage" means an accessory building designed or used for the storage of: 1) Single-family: Not more than four automobiles owned and used by the occupants of the building to which it is accessory and in which no business, commercial service or industry is carried on; 2) Multiple-family: Provided that on a lot occupied by a multiple-family dwelling, the private garage may be designed and used for the storage of 1½ times as many automobiles as there are dwelling units in the multiple-family dwelling. Geologic And Geotechnical Definitions Geologic and geotechnical terms. Active fault. The term "active fault" means a seismic (earthquake) fault displaying evidence of greater than four inches of surface displacement along one or more of its traces during the Holocene time (approximately 10,000 years ago to the present). Active landslide. The term "active landslide" means a landslide which is known to have moved or deformed and which has not been proven to be stable by a geotechnical investigation. Aquifer. The term "aquifer" is defined as a saturated permeable geological unit that can transmit significant quantities of water under ordinary hydraulic gradients. Aquifer recharge. The term "aquifer recharge" area means an area that has soils and geological features that are conducive to allowing significant amounts of surface water to percolate into groundwater. Area of deformation. See "zone of deformation." Critical acceleration. The term "critical acceleration" means the minimum amount of ground acceleration during seismically induced ground movement required to induce liquefaction or other forms of ground disruption. Critical facilities. The term "critical facilities" means: 1) Lifelines such as major communication, utility and transportation facilities and their connection to emergency facilities; 2) Essential facilities, such as: a) Hospitals and other medical facilities having surgery and emergency treatment areas; b) Fire and police stations; c) Tanks or other structures containing, housing, or supporting water or other fire suppression materials or equipment required for the protection of essential or hazardous facilities, or special occupancy structures; d) Emergency vehicle shelters and garages; e) Structures and equipment in emergency-preparedness centers; f) Standby power generating equipment for essential facilities; g) Structures and equipment in government communication centers and other facilities required for emergency response; h) Hazardous facilities such as structures housing, supporting or containing sufficient quantities of toxic or explosive substances to be dangerous to the safety of the general public if released; or i) Special occupancy structures, such as: i) Covered structures whose primary occupancy is public assembly (capacity greater than 300 persons); ii) Buildings for schools through secondary or day care centers (capacity greater than 50 students); iii) Buildings for colleges or adult education schools (capacity greater than 50 students); iv) Medical facilities with 50 or more resident incapacitated patients, but not included above; v) Jails and detention facilities; j) All structures with occupancy greater than 5,000 persons; k) Structures and equipment in power-generating stations and other public utility facilities not included above, and required for continued operation; l) Unique or large structures whose failure might be catastrophic, such as dams holding over ten acre-feet of water. Debris flow. The term "debris flow" means a mass of rock fragments, soil, and mud which, when wet, moves in a flow-like fashion. Debris flows will follow a confined channel, but may alter course if present on an alluvial/debris fan surface. Engineering geologist. The term "engineering geologist" means a geologist who, through education, training and experience, is able to assure that geologic factors affecting engineering works are recognized, adequately interpreted and presented for use in engineering practice and for the protection of the public. This person shall have: 1) At least a four-year degree in geology, engineering geology, or a related field from an ABET-accredited college or university; 2) At least three full years of experience in a responsible position in the field of engineering geology; and 3) A Utah State Professional Geologist's or Professional Engineer’s license. Engineering geology. The term "engineering geology" means the application of geological data and principles to engineering problems dealing with naturally occurring rock and soil for the purposes of assuring that geological factors are recognized and adequately interpreted in engineering practice. Fault. The term "fault" means a fracture in the earth's crust forming a boundary between rock or soil masses that have moved relative to each other (also see "active fault"). Fault scarp. The term "fault scarp" means a steep slope or cliff formed directly by movement along a fault. Fault trace. The term "fault trace" means the intersection of the fault plane with the ground surface. Fault zone. The term "fault zone" means a corridor of variable width along one or more fault traces. Geotechnical report. The term "geotechnical report" means a technical report or study prepared by a geotechnical professional who is qualified in the field of expertise examined and analyzed in such a report. A person shall be considered "qualified" upon presentation of credentials providing recognition in the professional field, an academic degree from an accredited college or university in geology, geotechnics and/or geotechnical engineering. Landslide. The term "landslide" means a general term for the down slope movement of a mass of soil, surficial deposits or bedrock. Liquefaction. The term "liquefaction" means a process by which certain water saturated soils lose bearing strength because of ground shaking and increase of groundwater pore pressure. Liquefaction potential categories depend on the probability of having an earthquake within a 100-year period that will be strong enough to cause liquefaction in those zones. High liquefaction potential means that there is a 50 percent probability of having an earthquake within a 100-year period that will be strong enough to cause liquefaction. Moderate means that the probability is between ten percent and 50 percent, low means that the probability is between five percent and ten percent, and very low means less than five percent. Natural hazard. The term "natural hazard" means any hazard listed in section 108-22-2, including, but not limited to, liquefaction, surface fault rupture, rock fall, debris flow, flood, tectonic subsidence, landslide and other hazards. Natural hazard map. The term "natural hazard map" means any map that has been published by a qualified professional or applicable governmental agency, which contains the best available information, as determined by the county engineer, and which delineates a potential natural hazard. Natural hazard study area. The term "natural hazard study area" means any area identified on any natural hazard map or within any natural hazard studies or reports as having potential for being a natural hazard. In addition, the county engineer has discretion to identify a natural hazard study area as a new hazard or potential hazard becomes known. Rock fall. The term "rock fall" means the gravity-induced drop of a newly detached segment of bedrock or perched rock of any size from a cliff or steep slope. Structure designed for human occupancy. The term "structure designed for human occupancy" means any residential dwelling or any other structure used or intended for supporting or sheltering any use or occupancy which is expected to have occupancy rate of more than 2,000 person-hours per year. Zone of deformation. The term "zone of deformation" means the zone along a fault in which natural soil and rock materials are disturbed as a result of movement along the fault. Gf-Gz Definitions Glare. The term "glare" means light, originating from a direct artificial light source, or any light reflected off a reflective surface, that causes visual discomfort or reduced visibility. Grade, finished. The term "finished grade," or any of its variations, means the final slope of the ground after being altered from natural grade. Grade, natural. The term "natural grade," or any of its variations, means the slope of the ground as it existed immediately prior to any grading or recontouring done as part of or in anticipation of approval of a land use permit. Gross acreage. See "acreage, gross." Guest house. The term "guest house" means a separate dwelling structure located on a lot with one or more main dwelling structures and used for housing of guests or servants and not rented, leased, or sold separate from the rental, lease or sale of the main dwelling.
