Noosa Lot 4 Early Learning Centre RFI Response 12.04.23 · MCU22/0094

As requested by Council, the plans have been prepared with additional information supporting the
location, size and general features of on-site stormwater management. The SMP demonstrates the
stormwater quality and quantity treatment measures for the site, ensuring it’s appropriately managed
across the site. Ultimately, the SMP demonstrates how the proposed bioretention device is sufficient
to service the site with consideration to flows and discharges.

ITEM 2
Concern is raised in relation to the amenity and safety aspects (given the use and presence of small
children) of the end-of-line bioretention device. The device set-down and degree of retaining wall use
appears to conflict with Tables 8 and 9 of the Bioretention Technical Design Guidelines (Water by Design,
2014). Regardless of the guideline requirements, specific care should be taken given the proposed use,
to ensure the design outcome does not present a hazard to children.
Information Required
1. Provide an updated SWMP and preliminary engineering plans, which:
    a. achieves a higher level of landscape integration by minimising bioretention system surface set-
        down relative to surrounding areas and minimises retaining walls consistent with the allowances
        specified in the Bioretention Technical Design Guidelines (Water by Design, 2014);
    b. includes a safety risk assessment that demonstrates that the design does not pose an
        unacceptable risk to children without fencing being required;
    c. gives greater consideration to the use of at-source bioretention devices within the car parking
        areas.
2. Clarify how users can safely exit a vehicle parked in space 13 given the proximity of the bioretention
    device and retaining wall.

Our Response
Please refer to Attachment 1 – Amended Architectural Plans and Section 2 of this letter.

In response to Council’s concern associated with the amenity and safety aspects of the bioretention
system, the design of this system has been revisited so that a timber look bridge, arbour, and
balustrades have been proposed with the predominant purpose of establishing a convenient and safe
pedestrian linkage between the key pedestrian and cycle pathway/easement along the western side
of the site and the Early Learning Centre.

A raised garden bed with seating incorporated is proposed around the bioretention device, acting as
both a physical and visual barrier between the device and movement areas. The redesigned
bioretention and associated treatments achieves a greater integration with the surrounding
landscape features, all whilst improving on vehicle and pedestrian safety. Moreover, the amendments
establish clear and legible movement paths, ensuring that manoeuvring, access and egress can be
achieved in an efficient and safe manner.

ITEM 3
Condition 53a of the reconfiguration approval (RAL18/0023) requires 10 metres of planting to the front
of the site:
    a. Local native plant species suitable for the location in mulched garden beds within the lots that
         from to Hofmann Drive and the future extension of Hofmann Drive that are 6m wide to the

                                                    4
