and welcome to the July edition of “Keep Things Flowing”, the
monthly newsletter presented by Storm Water Consulting.
In this month’s
newsletter Steve reviews a Sediment and Erosion Control workshop
that he attended earlier in the month, we answer another frequently
asked question and we provide you with some updates from the
month I attended a Sediment and Erosion Control Plan workshop. The
workshop was presented by Grant Witheridge and was part of
Stormwater Queensland’s Winter School.

was attended by approximately 20 participants, which included
Council officers (from various Council’s throughout Queensland), civil
engineers, civil drafters, engineering technologists and graduate
engineers. The workshop focused on the process behind the preparation
of sediment and erosion control plans, which included:
engineers we are often responsible for locating and sizing
treatment areas on a site. The civil design works are then undertaken
to ensure runoff from the development is directed into these areas.
Often the treatment areas provided as part of the sediment and
erosion control plans are converted into the final stormwater
treatment for the site once construction is completed. It would
therefore be highly beneficial if the developer could rely on one
consultant to provide both the sediment and erosion control plan
and the stormwater management plan. At the very least a good
understanding of the preparation process behind the sediment and
erosion control plan will benefit the developer. By attending this
workshop I have learnt how to prepare sediment and erosion control
plans and I aim to prepare these plans for future projects.
I plan to
develop my property which is located adjacent to Brisbane City
Council’s Overland Flow Flood Planning Area. As my property is not
located within the Overland Flow Flood Planning Area, do I have to
consider the overland flow in the area and do I have to meet the
requirements of the Flood Overlay Code?
property is not located within the Overland Flow Flood Planning
Area (and no other Flood Planning Areas) the Flood Overlay Code is
not required to be met. However, it should be understood that the Overland
Flow Flood Planning Area is not representative of the actual flood
prone land and is only indicative that there is an overland flow
issue in the area. The overland flow needs to be further assessed
by a hydraulic engineer. Given that there is overland flow in the
area (although it may not be on the subject property) the
development should still be designed to meet the requirements of
the Flood Overlay Code in order to provide a safe and sustainable
have recently found that Brisbane City Council is tightening up on
the trafficable access requirement for developments. In some cases
a stormwater emergency management plan is not an acceptable method
of addressing the trafficable access requirement and development
has been refused. It is critical that we ensure access to the
development property is not cut off during a flood event.
this month SPEL announced that they have gained approval for their
SPELFilter in Logan City Council.

of their software (v6.2).
