IDAS Form 27 - Cooroibah

A scale map/sketch plan of the site and the neighbouring area identifying:   Confirmed
• the site of the proposed works on the waterway
• the names of the waterway and the catchment in which the waterway is
  located
• stream order
• where the (site) waterway joins with another, more major waterway (or
  coastal waters) downstream
• other easily identifiable geographical features adjacent to the proposed
  works
• the limit and area of impounded waters (upstream weir pool) at full
  supply level (if relevant).
GPS coordinates and zone references of the works site (GDA94                 Confirmed
preferred).
Photographs of the site and the waterway upstream and downstream of          Confirmed
the works site.
A scale plan showing the limit of and area of impounded waters at full       Confirmed
supply level.
Details of the proposed development for all applications
Justification and the benefits of the proposed waterway barrier works.       Confirmed
Assessment of lesser impact alternatives and reasons for the proposed        Confirmed
waterway barrier.
Details of the proposed waterway barrier.                                    Confirmed
Details of the structure and management of the impoundments.                 Confirmed
Details of the proposed maintenance program on the waterway barrier          Confirmed
after construction.
A statement addressing the relevant part(s) of the State Development         Confirmed
Assessment Provisions (SDAP).                                                Not applicable
Details of the waterway for all applications
A scaled plan showing a cross-section of the stream profile at the           Confirmed
proposed location.
Description of the stream morphology at the proposed location, and up to     Confirmed
1 km upstream and downstream (e.g. width and depth of stream, stream
bed substrate types, bank stability, presence of pools, rifle runs, sand
bars, etc.).
Description of the riparian habitats at and adjacent to the proposed         Confirmed
location (e.g. Intact native vegetation, presence of weeds and other
disturbances).
Description of the stream hydrology (e.g. flood frequency and height,        Confirmed
altered flow regimes due to existing waterway barriers)
• Note: for most applications involving permanent waterway barriers on
  larger waterways, specific data on stream hydrology and flood levels
  will be required.
