The adverse impacts from sheet flow on the state controlled road network are prevented
SWC Response
The development does not result in adverse impacts from sheet flow on the state controlled
road network. All runoff will be directed into the waterway on the eastern side of the site.
RFI Item
Existing stormwater drainage infrastructure on state controlled roads is not interfered with
or damaged such as through concentrated flows, surcharging, scour, or deposition; and the
quality of stormwater discharging onto the state controlled road is not reduced through
erosion and sedimentation.
SWC Response
The development marginally increases the velocity at a single cross-section in the hydraulic
model. The velocity at XS20 is increase by .03m/s. This increase is considered to have a
negligible impact on any potential erosion and scouring and no impact on state controlled
roads is expected.
