Existing cross runway designation Environmental Incident Airshed Any event or impact on the environment involving Perth Airport and/or its contractor’s actions or assets that is A geographical area within which the air frequently is capable of: confined or channeled, with all parts of the area thus being • causing harm to the environment or any person or property, subject to similar conditions of air pollution. • causing pollution, and/or Airside • coming to the attention of an environmental regulatory agency. The movement area of an airport, adjacent terrain and building or portions thereof, access to which is controlled. Estate Approaches The grounds and tenancies associated with the Perth Airport land holdings. The course to be followed by an aircraft in approaching for a landing or in joining a traffic pattern. Eulerian model Apron Defines specific reference points in a gridded system that monitors atmospheric properties, including temperature, A defined area on a land aerodrome intended to pressure, chemical concentration of tracers, over time. accommodate aircraft for loading and unloading passengers, mail or cargo, fuelling, parking or maintenance. Events per year (EY) Average Return Interval (ARI) Used as the measure of the rarity of a rainfall events that are likely to occur once or more than once per year. E.g. A measure of the rarity of a rainfall event. e.g. 1 in 50 year, two EY is used to indicate a rainfall event that is likely to 1 in 100 year etc. It is defined as the average, or expected, occur two times per year or more. value of the periods between exceedances of a given total rainfall accumulated over a given duration. Periods Excavator between exceedances are random. A machine used for excavating soil or sediment material Baseline and may include a backhoe excavator, bulldozer, dredge or other similar equipment. A specific value or values that can serve as a comparison or control a basic standard or level; guideline. Fauna Bio-accumulative The animals of a given region or period considered as a whole. The accumulation within living organisms of toxic substances occurring in the environment. Flora Bund The plants of a particular region or period, listed by species and considered as a whole. An embankment of earth or a wall constructed of brick, stone or concrete to form the perimeter of a compound Grade separation that will prevent lateral movement of the material Method of aligning a junction of two or more surface contained within the embankment or wall. transport axes at different heights (grades) so that they Corridor will not disrupt the traffic flow on other transit routes when they cross each other A restricted path along which an aircraft must travel to avoid hostile action, other air traffic, etc. Gaussian model Declared Rare Flora In probability theory and statistics, a Gaussian process is a particular kind of statistical model where observations occur The flora protected under theWildlife Conservation Act in a continuous domain, e.g. time or space. In a Gaussian 1950 (State) due to it being rare, in danger of extinction, or process, every point in some continuous input space is otherwise in need of special protection associated with a normally distributed random variable. 392 New Runway Project | Preliminary Draft Major Development Plan May 2018 Appendices General Aviation (GA) Landside Refers to all flights other than military and scheduled airline That portion of an airport not designated as airside and to flights, both private and commercial. which the general public normally has free access. Greater Perth Living Stream Used to describe Perth’s Greater Capital City Statistical A constructed or retrofitted waterway that mimics Area (GCCSA), a geographical area designed to represent the characteristics of a natural stream. Water quality the functional extent of Western Australia’s capital city. improvement is achieved by aquatic vegetation and natural Greater Perth consists of the area defined by the Perth biological processes helping to oxygenate the water and Metropolitan Region, with the City of Mandurah and the removing nutrients plus non-nutrient contaminants. Pinjarra Level 2 Statistical Area of the Shire of Murray Movement Greenfield Area Either a take-off or a landing by an aircraft. An undeveloped or agricultural tract of land that is a potential site for industrial or urban development. Movement areas That part of an aerodrome to be used for the surface Ground Disturbing Activities movement of aircraft, including the manoeuvring areas The disturbance of earth or waters involving machinery and aprons. including clearing, excavation, backfilling and compacting, but excludes geotechnical investigations, surveying, N65 Contour fencing and rehabilitation works. N65 contour map for Perth Airport illustrates the average number of events per day over 65 decibels dBA for a Ground-based particular area. This corresponds to an outdoor sound Located on the ground as opposed to in an aircraft or in level of 65 decibels dBA and an indoor noise level of airspace. approximately 55 decibels dBA. Habitat Tree Native Vegetation Mature native tree containing hollows that may be suitable Any local indigenous plant community containing for habitat of native fauna. throughout its growth the complement of native species and habitats normally associated with that vegetation type Hardstand or having the potential to develop these characteristics. A hard-surfaced area on which heavy vehicles or airplanes It includes vegetation with these characteristics that can be parked. has been regenerated with human assistance following disturbance. It excludes plantations and vegetation that Hydraulics has been established for commercial purposes. Study of the motion of liquids using the laws of physics. Noise Contour In this case, flow in open channels, pipes, weirs and another stormwater infrastructure. Developed by the [then] Commonwealth Department of Infrastructure and Transport to illustrate the average Hydrology number of events per day that exceed a certain sound Study of the stormwater runoff generated by rainfall in level. connection with geography and geology. e.g. An asphalt Noise Event road generates more runoff per square meter than a lawn does. An event begins when the noise level exceeds a certain threshold value set in the noise monitor (which will be Initial Ground Disturbing Activities above the background noise level) and ends when the The disturbance of earth or waters involving machinery noise level drops below it. including clearing and excavation to a depth of 0.5 metres, Phytophthora but excludes geotechnical investigations, surveying, excavation in excess of 0.5 metres, backfilling, compacting, A group of fungi of the genus Phytophthora, which cause a fencing and rehabilitation works. serious plant disease. Lagrangian model Pollution Takes the perspective of a finite element or so-called ‘air The direct or indirect alteration of the environment to parcel’. Over time both the position and properties of this its detriment or degradation, to the detriment of an air parcel are calculated according to the mean wind field environmental value, or is of a prescribed kind from an data. The path along which air parcel travels is called its emission (as defined by theEnvironmental Protection Act trajectory. 1986 (State)). New Runway Project | Volume B: Environment, Heritage and Traffic Assessment 393 Appendices Precinct A space or place of definite or understood limits. Priority Flora Flora that is recognised by the Department of Biodiversity Conservation and Attractions as being under threat and in urgent need of further study; but is not yet declared rare flora under theWildlife Conservation Act 1950 (State). Priority Flora is divided into Priority 1, Priority 2, Priority 3 and Priority 4 listings, with Priority 1 being the flora most under threat. Receptor Various devices that receive information, signals etc Retention Storage An area that will store water until it has infiltrated into the ground and/or evaporated. Step-Change A significant change, especially an improvement Taxiway A defined path on an aerodrome established for the taxiing of aircraft and intended to provide a link between one part of the aerodrome and another. Water level indicator A round steel post with a flat marked gauge plate of white background and black one-centimetre increment gauge markings each with a total nominal length of two metres. Watercourse A river, creek, gully, brook or irrigation channel that contains or has contained water, but excludes wetlands. Wetland Land that is permanently, seasonally or intermittently waterlogged or inundated with water, but excludes watercourses. Windrow Line of stockpiled material, such as soil or vegetation. 394 New Runway Project | Preliminary Draft Major Development Plan May
