Temporary bund installed (where required) to
prevent stormwater runoff from entering bulk of
system. Bund keyed into batters of bioretention
and crest level higher than pits and weirs.

 

Temporary protective covering (filter cloth + 25
mm topsoil + turf) installed within bunded area.

OPTION 3 - SEDIMENT BASIN AND
BIORETENTION FUNCTION

Continuous sediment fences installed around
perimeter of filter media and top of batter

Sediment basin installed upstream of bioretention
in accordance with either (including hydraulic
structures):

* WSUD Technical Design Guidelines for SEQ
(SEQHWP)

+ Local erosion and sediment control guidelines or
Best Practice Erosion and Sediment Control
(IECA, 2008)

Suitable access provided to sediment basin for
clean out
