Oregon Administrative Rules › Chapter 632 - DEPARTMENT OF GEOLOGY AND MINERAL INDUSTRIES › Division 5 - TSUNAMI INUNDATION ZONE › Section 632-005-0020 - Definitions

Current through Register Vol. 63, No. 7, July 1, 2024
(1) In addition to
			 the definitions in ORS
			 455.447, the following
			 definitions shall apply unless another definition is clearly indicated by
			 context:
(a) "Board" means the Governing Board
			 of the Department of Geology and Mineral Industries.
(b) "Capacity" means the maximum allowable
			 occupants that may be served in the facility or structure in accordance with
			 applicable laws or other authority.
(c) "Competing interests and other
			 considerations" means any well-founded consideration that is reasonably related
			 to balancing or management of tsunami risks. It includes, but is not limited
			 to, scientific data regarding tsunami risks and mitigation measures such as
			 evacuation strategies.
(d)
			 "Consultation" means information provided by the department to a prospective
			 developer during information transfer under ORS
			 455.447 and OAR 632-005-0060. It
			 includes, but is not limited to, printed material; references to scientists,
			 engineers, or others with expertise in matters relating to tsunami hazards;
			 reports summarizing information known about the site or surrounding area;
			 information derived from field visits; and recommendations regarding potential
			 mitigation measures. Consultation is not binding.
(e) "Department" means the Oregon Department
			 of Geology and Mineral Industries.
(f) "Developer" means local governments,
			 districts, or other persons proposing to develop new essential facilities,
			 hazardous facilities, major structures, or special occupancy structures that
			 are addressed by ORS 455.446 to
			 455.447 and these
			 rules.
(g) "Exception" means a
			 board order under ORS
			 455.446(1)(d)
			 and OAR 632-005-0080  allowing the siting of a facility or structure that would
			 otherwise be prohibited by ORS
			 455.446(1)(a).
			 An exception is not a land use or building codes approval.
(h) "Mitigative construction strategy" means
			 a design plan that reasonably provides for evacuation to higher floors or
			 unhindered site evacuation with a reasonable expectation of safety in the event
			 of a tsunami.
(i) "Mitigative
			 terrain modification" means landscaping that can reasonably be expected to
			 mitigate tsunami risk for the site in question. It may include, but is not
			 limited to, placement of fill on the site, berms or other protective features
			 around the site, or ground armoring to limit tsunami erosion beneath or around
			 facilities or structures. In this context, ground armoring does not necessarily
			 include sea wall construction.
(j)
			 "New," when referring to a facility or structure, means that application for
			 land use or building permit or change in use approval was made on or after the
			 effective date of these rules.
(k)
			 "Risk" means the threat to people posed by a tsunami hazard for the proposed
			 use of a site.
(l) "Tsunami hazard"
			 means, as determined by scientific expectation, the size of the tsunami, the
			 kind of tsunami action, including velocity, and the estimated recurrence
			 frequency of the tsunami event for a given site.
(m) "Tsunami inundation zone" for the purpose
			 of these rules means the area subject to tsunami inundation as depicted on maps
			 adopted under OAR 632-005-0030  of these rules and intended for the
			 implementation of ORS
			 455.446 and ORS
			 455.447.
(n) "Water-dependent" means a use or activity
			 which can be carried out only on, in, or adjacent to water areas because the
			 use requires access to the water body for water-borne transportation,
			 recreation, energy production, or source of water.
(o) "Water-related" means uses which are not
			 directly dependent upon access to a water body but which provide goods or
			 services that are directly associated with water-dependent land or waterway
			 use, and which, if not located adjacent to water, would result in a public loss
			 of quality in the goods or services offered. Except as necessary for
			 water-dependent or water-related uses or facilities, residences, parking lots,
			 spoil and dump sites, roads and highways, restaurants, businesses, factories,
			 and trailer parks are not generally considered dependent on or related to water
			 location needs.
