| AVERAGE RECURRENCE INTERVAL
(ARI) |
| The long-term average number of years between the occurrence
of a flood as big as (or larger than) the selected event.
For example, floods with a discharge as great as (or greater
than) the 20-year ARI flood will occur on average once
every 20 years. |
|
| BASIX |
| The Building Sustainability Index is a web-based planning
tool designed to assess the potential performance of new
homes against a range of sustainability indices: landscape,
stormwater, water, thermal comfort and energy. |
|
| CARBON DIOXIDE (CO2) |
| Carbon dioxide is the most significant greenhouse gas,
not because it is the strongest but because it is released
in such vast quantities, mainly as a result of burning
fossil fuels (coal, oil, and gas). Concentrations in the
atmosphere have risen rapidly (by 30%) since the industrial
revolution. |
|
| CARBON DIOXIDE EQUIVALENT (CO2-E) |
| Greenhouse gas emissions which include other gases
(for example methane) are often measured in tonnes of
carbon dioxide equivalent, which means the equivalent
amount of CO2 emissions which would have the same effect.

|
| GREENHOUSE GAS EMISSIONS |
| Greenhouse gases absorb heat and warm the lower atmosphere,
although they make up very little of it by volume (less
than 1%). In the absence of greenhouse gases the average
global temperature would be about -18oC, and the earth
would be uninhabitable. However, since industrialisation
the concentration of greenhouse gases has been rising,
mainly as a result of burning fossil fuels (coal, oil
and gas). CO2 levels, for example, have increased by 30%.
This is causing the climate to change, and the global
temperature to rise. The more common greenhouse gases
are carbon dioxide (CO2) and methane. |
|
| GREYWATER |
| Domestic wastewater excluding toilet waste but may
include wastewater arising from a hand basin, kitchen,
bath, shower and laundry. |
|
| MACROPHYTE ZONE |
| An area of plants such as rushes and reeds that improve
water quality by trapping fine particles and nutrients
such as nitrogen and phosphorus. |
|
| MASTERPLAN |
| An interpretation of the planning controls and urban
design principles for a site setting the framework for
future development. |
|
| MODERATE INCOME HOUSING |
| Housing that is affordable to those households on incomes
between $45,000 and $68,000 per year (2003 dollars). |
|
| NatHERS |
| The Nationwide House Energy Rating Scheme is a software
application that simulates the energy consumption of a
house design. Developed by the CSIRO in consultation with
Australian governments, NatHERS provides a rating of between
0 and 5 stars to show the potential of a house to be energy
efficient. The rating is based on a detailed computer
simulation of the house using hourly weather data. A rating
of 0 represents a poorly performing house, while a rating
of 5 is excellent. |

|
| OHS&R |
| Occupational Health, Safety and Rehabilitation. |
|
| POTABLE WATER |
| Water that is drinkable. |
|
| RIPARIAN CORRIDOR |
| A riparian corridor is the land directly adjacent to
or surrounding a natural or artificial waterway, including
rivers, intermittent or permanent creeks and streams,
wetlands and lakes. The corridors provide a crucial link
between land and water ecosystems. |
|
| RTA |
| Roads and Traffic Authority. |
|
| STAKEHOLDER |
| Any individual or group that has a vested interest
in the success of an organisation in delivering intended
results and maintaining the viability of the organisation’s
products and services. For example, the local community
is a stakeholder in a major construction development.
Stakeholders influence programs, products, and services. |
|
| TERRESTRIAL |
| Living or growing on land rather than in water or air. |
|
| TRIPLE BOTTOM LINE (TBL) |
| The concept of considering not just the economic value
a corporation creates, but also how its activities impact
society and the environment. |
|
| WATER SENSITIVE URBAN DESIGN
(WSUD) |
| WSUD refers to the design principles that aim to reduce
the impact of interactions between the urban built form
(including urban landscapes) and the urban water cycle
as defined by the three urban water streams of potable
water, wastewater and stormwater. |
