Good afternoon Andrew,

Thank you for providing the additional information we requested on the Cooroy mixed-use development. | have
reviewed the documentation and am satisfied that stormwater management, setbacks to the minor watercourse
and general treatment of the riparian corridor are in accordance with the Seqwater Development Guidelines. There
are a few points that were made informally (in emails) or touched upon in reports that I’d like to confirm regarding
both the riparian buffer and the pump station, and also some uncertainties around the proposed pump station in
the absence of a report addressing this particular element of the proposal. To address these areas, | can provide the
following advice / recommendations:

¢ Seqwater supports the 20m average setback and riparian buffer width for all uses to the minor stream on
the subject site. The 10m additional buffer strip affords important additional protection to the watercourse
and riparian vegetation, given the high impact nature of some uses proposed. The response letter prepared
by Saunders Havill Group (Keira Grundy, dated 20 November 2014) and the Ecological Assessment Report
(EAR -prepared by Saunders Havill Group, dated 24 June 2014) both make brief reference to weeding and
revegetation of the 20m riparian buffer area, however no Rehabilitation and Weeding Management Plan
has been provided with the application material. The Landscape Masterplan (Prepared by Saunders Havill
Group, dated 10 February 2014) makes reference only to weeding in the riparian buffer area and planting in
the additional 10m buffer strip.

Given the degraded state of the existing riparian buffer (as evidenced in the aforementioned environmental
advices) and the high impact nature of some of the proposed uses within a drinking water supply
catchment, Seqwater considers it appropriate for a staged rehabilitation plan, including select and
controlled weeding and revegetation to be developed for the existing riparian buffer. This should occur in
addition to the proposed planting in the 10m buffer strip. It is recommended that a Rehabilitation and Weed
Management Plan is prepared by a qualified professional at the appropriate stage of development and
approved / endorsed by Council prior to development commencing on the site. Seqwater requests a copy of
any such plan for review when available.

e The Water and Sewerage Network Analysis (prepared by GHD, dated November 2014) mentions that it does
not cover internal site servicing. No report specifically addressing the private pump station required on site
has been prepared, therefore no information exists as to the capacity, maintenance or emergency response
measures associated with this infrastructure. Seqwater recommends the preparation of an Inspection and
Maintenance Schedule and an Emergency Response and Contingency Plan for the pump station.. This

should be endorsed / approved by the relevant authorities (Council, DEHP). Seqwater requests a copy of any
such plan for review when available.

e Should the location of the proposed on-site sewerage pump station change, Seqwater requires that this
facility maintains at least a 50m setback from the surveyed high bank of the watercourse on the site.

« Seqwater strongly supports provision of at least 25% and up to 50% more emergency storage capacity at
the pump station, than that required by the SEQ Sewer and Water Code.

e Seqwater requests to be included ona notification register in the event of any overflow / spill / other
sewage discharge event

Many thanks for your consultation in relation to the proposed development. If there is any further advice or
clarification you require, please contact me directly.

Kind regards,

Leah Snerling Senior Land Use Planner

Hi Leah

The proposed pump station is shown on drawing P003 and is about 50m from the stream/ waterway.

Also please find attached the sewer and water analysis report that has more information on the proposed pump
station. The pump station would have a warning system in the event of an emergency and we are proposing to have
emergency storage that is 25-50% larger than is required by the SEQ Sewer and Water Code. Also in the event that
both pumps stop working, the owner could stop all uses on site.

Please do not hesitate to contact me should you require any further information.

Kind Regards,

Andrew van Tonder
