Dear Noel,
RE: Comments regarding suitability of proposed waterway retention for proposed RAL at 25
Pavilion St, POMONA QLD 4568.
Please find herein my comments regarding the suitability of the proposed design for the waterway
retention at 25 Pavilion St, POMONA. My comments are made with reference to the revised POD
provided as Attachment 1 and in my opinion accord with the outcomes of the site meeting held on
Monday 20th December of which yourself, myself and Amanda Turner (Noosa Council Senior
Environment Officer) were in attendance.
The revised layout retains the cleared swale drain which is mapped as a waterway south of the
onsite dam and replaces the in line dam with a bio retention basin; Lot 600, which will be dedicated
to Council as drainage reserve.
It was agreed at the onsite meeting that the historical flow path associated with the mapped waterway
was likely to have flowed in a north westerly direction either past or partly through the dam and then
north along the western perimeter of the dam. This general alignment can be identified on the POD
which shows contours reflecting such. Given the current mapping does not reflect this, it was agreed
that the assumed historical flow path external of the proposed Lot 10 BLE should be captured in
covenant and rehabilitated. This enables the overflow from the bio retention basin to continue to be
discharged to the west where it would be captured in the existing north south aligned conveyance
flow path that will be positioned immediately adjacent to the basin.
The proposed covenant and rehabilitation design, inclusive of the bio basin, results in a 10-40m wide
riparian corridor being reinstated through the site which is an excellent biodiversity outcome for the
local area and will support the future rehabilitation prospects of downstream areas as they are
development overtime. The initiative also supports the even more significant biodiversity outcome
associated with the extensive revegetation and rehabilitation of the Riparian Protection Area in the
far west of the site. The revised layout is therefore unequivocally supported.
Note , the rehabilitation palette of the covenant area and bio basin should reflect the local regional
ecosystems in the area applicable to the underlying geology and also be cognisant of not
exacerbating bushfire risk and or storm damage to future lots.
Should you have any queries regarding this matter please do not hesitate to contact me.
Sincere regards,
