Information Required

2. Provide a detailed Erosion and Sediment Control Management Plan, prepared by a
CPESC or RPEQ, which includes information on, but not limited to:
        2.1. Staging of the works and how each stage will be stabilised immediately after
        being completed;
        2.2. How areas that are not part of the final cut/fill pad but will be disturbed as part
        of the works (access tracks, manoeuvring areas, etc.) will be stabilised in the short
        and long term;
        2.3. How “dirty” water will be managed;
        2.4. How “clean” water will be diverted from the destabilised area;
        2.5. How will diversion drains be stabilised, namely the ones that divert clean
        water;
        2.6. Maintenance regime of the proposed controls;
        2.7. Where the topsoil will be stockpiled and how it will be stabilised.

3. Provide CPESC or RPEQ certification that all proposed E&S controls, for each of the
proposed construction stages, have been sized in accordance with relevant standards
and legislation, and suitable contingency measures will be available onsite, or able to
be deployed to site prior to being required.

Response

An Erosion and Sediment Control plan accompanies this response. Note that the control
measures outlined in the report have been depicted on drawing 1995-C1101.

Issue
Building pad levels and building envelopes.
Information Required
4. Update the earthworks plan (DWG 19553-C1100A) to include minimum building pad
levels in order to demonstrate compliance with Condition 35.
5. Update the earthworks plan to show building envelopes and the current level of the dam
top-of-embankment on Lot 8 and demonstrate compliance with Condition 32(d) of DA
approval RAL19/0018.

4. Building pad levels have been added to drawing 19553-C1100 and confirm compliance
with condition 35, ie above 1% AEP.
5. Building envelopes have been added to drawing 19553-C1100 – lot 8 building envelop
has been amended to ensure it is above the dam top of embankment.
6. Lot 8 Building envelop has been amended so it does not encroach into the enlarged
dam. Note an additional building pad has been added for a storage shed on this lot.

Issue
Condition 7 of DA approval RAL19/0018 requires that: “A plan of the subdivision
overlaid on a current aerial photo must be prepared by a registered cadastral surveyor and
submitted to Council prior to the issue of an operational works approval.”
Information Required
7. Provide a plan that complies with the requirements of condition 7 of DA approval
RAL19/0018.
Response
7. A current aerial photo has been added to the plan of subdivision drawing 19553-C1002.
A letter certifying this plan has been provided by the Surveyor and accompanies this
response.

Issue
Conditions 11 and 26 of DA approval RAL19/0018 require that a “site-specific
geotechnical investigation for each approved lot” is prepared, including but not limited to
information on the location of the effluent disposal area.
Information Required
8. Provide a geotechnical report that complies with the requirements of conditions 11 and
26 of DA approval RAL19/0018.
Response
Individual geotechnical reports for each lot are attached to this response . We also provide
a copy of the effluent disposal report for the site which identifies the areas for disposal for
each lot/building pad.


Issue
Conditions 12d. and 12f. of DA approval RAL19/0018 require that the operational works
application includes details for: “street lighting, signage, linemarking and underground
services”; and “maintenance of suitable access (pedestrian and vehicle) to 21 Wilgee
Court during the construction phase of the works”, respectively.
Information Required
9. Provide detailed plans that comply with the requirements of conditions 12d. and 12f. of
DA approval RAL19/0018.
Response

Page 4

9. Streetlighting and underground services are shown on the electrical and NBN drawings
accompanying this response. Signage and linemarking are shown on the civil drawings
however we believe that no intersection markings or signage is necessary at the
intersection of Wilgee Court and Cordwood Drive. A note has been added to the drawings
to state that access to the existing house at 21 Wilgee Court is to be maintained at all
times. It should be noted that the existing concrete driveway is located within the future
verge area of the Wilgee Court extension so this can generally be retained until the new
road is completed. A temporary connection between the driveway and Wilgee Court will be
provided as necessary during construction of the road.

Issue
Condition 13 of DA approval RAL19/0018 requires that the operational works application
includes details for “a new intersection must be constructed joining proposed Road 1 with
Lake MacDonald Drive.”
Information Required
10. Provide detailed plans that comply with the requirements of condition 13 of DA
approval RAL19/0018, specifically with regards to signage, linemarking and services
(underground and overhead).
Response
10. Linemarking and signage details for the intersection of Road 1 and Lake Macdonald
Drive have been added to drawing 19553 – C1208. Lighting details have been provided on
the electrical plans.

Issue
Condition 17 of DA approval RAL19/0018 requires that the operational works application
includes details for concrete bin pads.
Information Required
11. Provide detailed plans that comply with the requirements of condition 17 of DA
approval RAL19/0018.
Response
11. Concrete Bin pads have been added to the drawings – refer 19553-C1200

Issue
Condition 22 of DA approval RAL19/0018 requires drainage easements over all
flowpaths conveying discharge from roads.
Information Request
12. Amend the engineering plans and provide supporting calculations to show drainage
easements over the 1%AEP flow width for all stormwater discharges from new or
proposed roads onto the new lots. Additional Easements are considered necessary for
Lot 1, Lot 2, Lot 3, Lot 9, Lot 15 and Lot 16.

Response

Page 5

12. Amended plan 19553-DG-CAT shows the location of easements over the 1%AEP flow
paths for all stormwater discharges from new and proposed roads onto the new lots. The
flow widths have been determined from the previous flood modelling undertaken for the
site plus an allowance of 3m width each side of the extent of flow.

Issue
No information has been provided to demonstrate compliance with conditions 39, 40, 43,
44 and 45 of DA approval RAL19/0018.
Information Required
13. Advise if compliance with the conditions 39, 40, 43, 44 and 45 of DA approval
RAL19/0018 will be undertaken by separate application for operational works or if the
current application will be amended to include compliance with the afore mentioned
conditions.
Response
13. Landscaping plans are attached to this response and we ask that these be assessed
as part of this application.

Issue
Condition 52 of DA approval RAL19/0018 requires that the applicant submits “any

Response
14. Energex have no objections to the civil works proposed – refer attached
correspondence. A copy of the landscaping and rehabilitation plans have been sent to
Energex and we await their response.

Issue
Advisory note 8 of DA approval RAL19/0018, requires a preliminary Construction
Management Plan to be submitted with the Operational Works application.
Information Required
15. Provide a preliminary Construction Management Plan in accordance with the
requirements of advisory note 8 of DA approval RAL19/0018.
Response
15. Preliminary Construction Management Plan attached. A more detailed plan will be
provided prior to the prestart meeting by the appointed contractor.

Issue
The submitted plans indicate 1 in 2 cut and fill batters on road reserve.

Page 6

Noosa Council’s Planning Scheme Policy 05 notes: “For roads where major earthworks
are required, wider road reserves are required. Road Reserves are to be 3.0m from top of
cut
batter and 3.0m from toe of fill batter.”
Information Required
16. Demonstrate how batters on Road Reserve are to be reasonably maintained if these
are to be turfed.
17. Demonstrate compliance of the proposed design with Council’s Planning Scheme
Policy 05.
Response
16. As shown in the landscaping plans provided all batters steeper than 1 in 4 will be
mulched and planted out.
17. As discussed with Mark Lewis due to the steepness of the site it is not possible to
provide road reservice widths that fully contain the road batters without adversely
impacting on the lot layout. As such is has been agreed that easements in favour of
Council will be provided in the front of the new lots where the road batter extends across
the property boundary. These easements are shown on the revised plans.

We trust the above is satisfactory. Should you have any queries regarding this
matter, please contact the undersigned.

Yours faithfully,
