Dear Sir/Madam
Re: MCU21/0156 ~ Lot 80 & 81 RP71151 & Lot 1 RP130594
89, 91 & 93 Eumundi Noosa Road, Noosaville
We have reviewed Noosa Council’s request for information dated 6 January 2022 and provide our response to
the Engineering related items.
Item 6: Traffic
“With regard to item 10b of the information Request, the raised median in Eumundi Noosa Road should extend
6m south of the proposed driveway in order to appropriately inhibit movements to left turns only.”
Response
Please refer to our updated Driveway & Access Plan – SCG Drawring No. 31131 – C6.1 Rev A, which
includes the extension of the raised median on Eumundi-Noosa Rd to be 6m South of the proposed
Driveway access to inhibit vehicle movements to left turns only.
Item 8: Waste Collection Vehicle (WCV)
“With regard to Item 10d of the Information Request, some elements have not been addressed. The bin area is
located to the rear of the site and the refuse truck has travel through the site to access, which is not ideal for
residents of the site. There has not been demonstration of where a refuse truck can pass a car in the main parking
aisle, having regard for the kerb build outs and first level building overhangs (for a truck moving along the aisle to
the bin area, a car travelling in the other direction needs to be able to pass the truck somewhere). Also, there has
been no assessment or proposed arrangements for how the bins will be operated (240 litre bins at remote
locations of the site, 1100 litre bins at the collection point, and max 60m bin travel by residents).
With regard to Item 10e of the Information Request, the proposal plan still needs further resolution in relation to
details of grades and levels, primarily in relation to how the flat garages will satisfactorily interact with the steeper
parts of the main access driveway, the 1:10 grade at the refuse collection area, and grades of up to 1:6 on the
pedestrian route.”
Response
There is ample sight distance for vehicles travelling along the main driveway with numerous queuing areas
between kerb indents including, maneuvering back into a garage if a WCV is entering the site as another
option. Regardless we have provided an excerpt view of a car passing (exiting site) an entering WCV. This
is shown on our revised Driveway and Access plan drawing No. 31131-C7.1 RevA.

With regards to Item 10c of the previous information request, we are satisfied that the proposed driveway
grades satisfy both AS2890.1-2004 and AS2890.2-2022 (Off Street Commercial Vehicle Parking). Detailed
design will be completed and submitted as part of the Operational Works application.
We don’t consider the 1 in 6.6 grade in a small section of pedestrian access paths as being unsafe.
However a series of steps could be included if Council deemed it necessary which can be conditioned a an
Operational Works required work.
Item 9: Fill Levels
“The plans indicate the areas to be filled, but the figures presented on the plans are the same for existing and
finished ground levels.”
Response
SCG Drg. No. 31131 C3.1 provides numerous spoil levels across cut/fill levels of the points.
Item 10: Stormwater
“The proposed bioretention/detention basin is surrounded by retaining walls and sits approximately 2.3m below
the adjacent pavement levels. This creates significant difficulties for access to and maintenance of the basin.”
Response
Refer to updated Stormwater Management Plan SCG Drg. No. 31131 – SW1.1 Rev A, which includes a
1.5m wide maintenance access ramp from the driveway down to the proposed bio retention/detention basin
area.
Item 11: Stormwater
“A significant portion of the site is proposed to be discharged to Eumundi-Noosa Rd even though none of the
existing site falls in this direction. An assessment of the impact of this change on the drainage in Eumundi-Noosa
Rd is required.”
Response
We have assessed the capacity of the Eumundi Noosa Rd Kerb and channel in accordance with Section
7.4 of QUDM 2017 & Aust Roads Guide to Road Design Part 5A Section 5.3, using a 3m flow width for the
10 Yr ARI (10% AEP). We confirm the Kerb and channel can safely convey the proposed post development
10% AEP catchment flows in addition to the existing catchment whist maintaining a 4m wide flood-free
trafficable lane on Eumundi Noosa Rd.
Item 12: Stormwater
“The SWMP does not include allowance for Climate change.”
Response
Refer to section 6.5 of the revised Stormwater Management Plan (No. 31131(SWMP).RevA) which now
includes climate change considerations for the 1% AEP event at year 2100. A copy of the revised plan is
included.
If you require any further information, please do not hesitate to contact our office.
