Response to Information Request - Final 21 March 2024 · MCU23/0096

 “Adamson Town Planning, specialising in providing higher order town planning advice”




provided by Council’s traffic consultant, which did not include a link road through the site
(refer email from Mr Glover dated 5 March 2019). Consequently, the GSLC installed a boom
gate to ensure that only staff could use these spaces, consistent with the above advice.

Issue - Stormwater

It is unclear how stormwater drainage to and from the proposed Performance Arts Building
and Carpark areas will be managed. The stormwater drainage system must connect to a lawful
point of discharge in accordance with the Water Quality and Drainage Code.

Information Required

10. Provide additional documentation demonstrating how stormwater to and from the
    proposed development areas will be managed and achieve lawful discharge in accordance
    with the Water Quality and Drainage Code.

Response:

TOD Consulting in association with Colliers have provided an updated Stormwater
Management Plan (SWMP) for the PAC development, which is provided as Attachment 7.

The SWMP has addressed the relevant issues under the Water Quality and Drainage Code.
This includes providing a new bio-basin to the east of the PAC to improve the treatment of
stormwater from the sealed parking areas (as shown) and for the majority of the roofed area
of the PAC. Some of the water from the roof of the PAC is to be reused onsite with
underground rainwater tanks to be provided. Further, the remainder of the roof water will be
discharged to rain gardens near the front of the PAC (refer Attachment 4).

The matter of water quality also needs to be considered in context having regard to the
existing development on the site when compared to the improvements being proposed. In
the circumstances, the proposed development will result in an improvement to the treatment
of stormwater and improved water quality outcomes for the site.

Issue – Sustainability

It is unclear how the proposed development will maximise water efficiency on site by
incorporating rainwater collection and reuse measures for non-potable purposes such as
irrigation in accordance with the Sustainable Building Design Code.

Information Required

11. Provide additional documentation addressing the requirements of the Sustainable Building
    Design Code.
