Dear Ben,
Response to Council Information Request – MCU22/0171
Proposed Dual Occupancy – 128 Gympie Tce, Noosaville
The following is in response to an Information Request issued by Noosa Regional Council regarding
the above development. Items are addressed in order as per the request and as far as we are able
to respond.
INFORMATION REQUIRED
Issue - Earthworks
The submitted documentation does not contain sufficient information for Council to assess the
earthworks required to carry out the proposed development.
Council have identified that the proposed development is encumbered by Council’s Acid
Sulfate Soils overlay. The proposed works includes significant excavations below the existing
water table. The submitted documentation does not include an Acid Sulfate Soils Management
Plan.
Information Required
6. Provide additional detail demonstrating the full extent of earthworks required to carry out
the proposed development. The additional detail must be prepared by a suitably qualified
person (RPEQ – Registered Professional Engineer of Queensland) and include, but not be
limited to:
a. the full extent of cut and fill;
b. the volume of cut, fill and excess earth; and
c. demonstrate how the proposed earthworks will not undermine the structural integrity of
adjoining properties.
7. Provide a dewatering plan demonstrating how Acid Sulfate affected water encountered
during excavation will be treated and disposed of. The dewatering plan must be prepared
by a suitably qualified person.
The Engineering Plans have been amended and now include additional earthworks information.
Detailed surface modelling was carried out and cross sections provided with the original submission
and additional cross sections have been produced along with a heatmap style earthworks plan to
identify the extent and depth of excavation. The modelled surfaces have also been used to measure
the excavation quantity and this is now noted on the plan. The depth of excavation adjacent to the
side boundaries ranges, up to 2.5m below the existing surface.

It is expected that conventional ground support methods will be adequate to ensure the stability of
the adjacent structure(s) during excavation and construction of the basement. A comprehensive
geotechnical investigation has not yet been undertaken to determine the specific properties of site
soils, but it is generally expected that sand/silt and other alluvial soils will be present throughout the
excavation and below the adjoining lots. See below data/image from the Queensland Geotechnical
Database.
QGD Image – Subject Site
Driven steel sheet pile or contiguous pile retaining walls are likely to be the most suitable for this site
(depending on the presence of dense material or rock), but other methods including soil
nailing/diaphragm wall and/or internal bracing options could be suitable, particularly with the
narrow site. Shoring methods that form permanent retaining walls have obvious advantages on this
site with the space limitations and clearances to side boundaries. If dense material or rock is
encountered it is expected to be minimal and rippable. Extensive rock breaking is not expected for
this project.
The site is in close proximity to the Noosa River and tributaries. Groundwater is expected at or
about the depth of excavation and dewatering will be necessary to enable construction of the
basement. Given the narrow width of the site, proximity to the river, tidal influence and the
expected groundwater level relative to the depth of excavation, the dewatering processes should be
limited to managing inflow into the excavation area only; by local drainage and sumps/pumps.
Spears/wells to lower the groundwater beyond the site is not anticipated.
A detailed geotechnical investigation will be undertaken to inform the Operational Works and
building structural designs. We don’t consider the geotechnical conditions on site to be an
engineering constraint that warrants further investigation and cost at the MCU stage of the project.
Furthermore a detailed Acid Sulphate Soils Management Plan and comprehensive dewatering plan

that addresses water quality, will be developed following the geotechnical investigation as geological
and groundwater features are confirmed. Council will have the opportunity to review these at the
Operational Works stage of the development.
Issue – Access
There is insufficient information on the internal driveway and to demonstrate how the
internal driveway will function when a vehicle is entering and another is existing the internal
driveway.
Information Required
8. Provide additional detail on the proposed driveway and access. The detail must be
prepared by a suitably qualified person (RPEQ – Registered Professional Engineer of
Queensland) and include, but not be limited to:
a. levels and grade of the access driveway;
b. a longitudinal section extending from the centre of the formation along Mill Street
to the beginning of the downward slope of the basement ramp; and
c. c. demonstrate that a B99 vehicle will not scrape or bottom out while entering or
exiting the access driveway.
d. d. demonstrates how the internal driveway will function in the event a B99 vehicle
is entering while another is exiting
The engineering drawings previously submitted included layout plans with design surface levels and
contours, as well as a driveway long section for the basement ramp to demonstrate satisfactory
vertical clearance. A low clearance B85 vehicle model was used for the vertical clearance
assessment and due to the limited width available with the narrow lot configuration. The amended
engineering drawings now show an extended long section and additional turn paths for a B99
vehicle. A B99 can be accommodated in the basement parking spaces as shown, noting that there is
space for 2 larger cars in the front area east of the ramp. A ground conflict report is also now
included, demonstrating that a low clearance B85 vehicle maintains at least 100mm ground
clearance whilst traversing the grade change sections at the top of the ramp, and 80mm clearance at
the transitions at the bottom of the ramp. The proposal is in accordance with AS2890.1 Section 2.6
and Appendix B for a residential development.
The amended engineering drawings now include additional information to demonstrate that there
are passing opportunities within the existing and proposed driveway geometry. The existing
easement driveway section is wide enough (5.5m) to allow for 2 B99 vehicles to pass. There is also
sufficient space for a vehicle to wait in the front area to the east of the ramp whilst another vehicle
is using the ramp access. A conflict between a vehicle entering and exiting is not expected to occur
frequently.

Issue – Variation in Flood Gate between Plans
The location of the proposed flood gate is shown along the west boundary in DME Projects’
Stormwater Details (220508-05), while it is shown at the peak of the downward slope of the
driveway in Sparks Architects’ Driveway (DD 1.4).
Information Required
9. Clarify the proposed location of the proposed flood gate.
10. Provide comment discussing why the proposed location is the most suitable for the
proposed flood gate. Noting that the proposed development must not adversely affect
the existing drainage conditions of the subject site and neighbouring properties.
The amended engineering drawings show the flood gate in the location as per the Architectural
Plans. This is considered to be the most appropriate location as the flood gate installation will also
incorporate a separate strip drain to capture surface water runoff to function as the driveway
drainage system in ordinary rainfall events, discharging to the street. A very small catchment from
the easement driveway (8m2) reports to the drainage pit at the front of the subject site and is
discharged to the street. This is considered to be a cost-effective drainage outcome, minimising the
infrastructure required. There are no other external catchments impacted by the proposed works.
Issue – Flooding
The subject site is located in Council’s Flood Hazard overlay and is adjacent to the Noosa
River and Canal. Council are concerned regarding the functionality of the proposed
stormwater system and associated infrastructure during, up to and including, 1% AEP events
and at the end of the development’s lifespan. Council predict that the yearly average rainfall
will increase approximately 20% towards the end of the development’s life span (2100).
Information Required
11. Provide additional detail and comment demonstrating how the proposed stormwater
system and associated infrastructure will function during, up to and including, 1% AEP
events and when experiencing an average annual rainfall increase of 20% by the year
2100. The additional detail and comment must be prepared by a suitably qualified
person (RPEQ – Registered Professional Engineer of Queensland) and include, but not
be limited to:
a. the functionality of the proposed kerb outlet during a flood event in which the outlet
is submerged
The engineering drawings now include additional details, specifically surface levels and pipe invert
levels for the proposed drainage system. These clearly show that there is sufficient hydraulic grade
for the system to function as intended in a design event (5%AEP Roofwater and surface water). The
kerb invert level at the outlet is approx. 1.25m AHD. Noosa Council infrastructure mapping shows
underground stormwater networks to the east and west of the subject site, discharging to
appreciable open channel in Mill St and canal system in close proximity to the development site.
These both discharge directly into the Noosa River. A brief drainage assessment concludes that a
difference in water surface level of >350mm is achieved between the lowest internal drainage

structure (flood gate strip drain) and the submerged outlet in Gympie Terrace - during an event
where all drains are at capacity and overland flows are active between Gympie Terrace and Mill St.
The below images identify the flow paths and critical levels at location just before surface flows are
considered to be free draining to the river. Images show that generally there are no obstructions to
flow once water levels overtop the back of kerb and verges and can flow to the river. The water
surface level in Gympie Tce at which the internal system will cease to be 100% effective for site
catchments is RL 1.75m. This outcome does not rely on capacity of the underground network. An
increase in average rainfall will not impact on the performance of the overland flow paths identified.
If water level in Gympie Terrace exceeds RL1.75 it is likely to be a result of riverine flooding. Under
these conditions the strip drain/flood gate channel can not free drain to the street and the flood
gate will start to activate (from internal catchment runoff only). Non-return devices in the outlet
pipes will ensure that flood gate strip drain is isolated from the rest of the system and that external
flood waters do not flow back into the site.

Issue – Stormwater Management
The submitted documentation does not include sufficient information for Council to assess
how the proposed development will collect and release stormwater. The submitted
documentation indicates that a stormwater pump will be used to discharge rainwater
collected in the proposed northern strip drain to the proposed drainage outlet along Gympie
Terrace. Council is unlikely to support the use of stormwater pumps.
Information Required
12. Provide additional detail demonstrating how the rainwater collected on-site will be
controlled, collected and released without causing scour damage to neighbouring
properties and without the use of a stormwater pump. The additional detail must be
prepared by a suitably qualified person (RPEQ – Registered Professional Engineer of
Queensland) and include, but not be limited to:
a. demonstrate that all other means of basement drainage have been exhausted;
b. demonstrate how the basement will drain any incidental rainwater and rainwater
captured from the strip drain during a power failure;
c. provide additional detail on the proposed basement sump and automatic pump;
d. demonstrate how the proposed basement sump and automatic pump will discharge
to the street; and
e. demonstrate the proposed southern-most strip drain can achieve the required
minimum grade (1:200).
Roofwater and surface water catchments are generally free draining to Council stormwater
infrastructure in Gympie Terrace. A small surface catchment at the rear (north) of the site will
discharge as incidental sheet flows to Chaplain Park. This catchment is approximately 100m2 and
consists of pool, pool surrounds and pervious landscaped areas. Infiltration is expected to be high

due to the sandy soils and scouring/nuisance from stormwater flows in the park area resulting from
this development is not expected.
A small catchment (25m2) from the ramp section of the driveway cannot be free draining to the
street as it is below kerb invert level. The lower strip drain is proposed specifically for this
catchment. 1%AEP 5min peak flows will be 2.4l/s and well within the capacity of a 100mm pipe at
1% grade. This same event would deliver 693l of water to the basement sump. A 600 sq pit is
proposed as the basement sump. This has a holding capacity of around 200 litres. Typical
stormwater packaged pump stations are supplied with pumps capable of transferring >150l/m
(2.5l/s) at 2m head. See link https://www.strongmanpumps.com.au/product/storm-water-drainage-
system.
In the unlikely event that the sump pump completely fails, 1%AEP runoff could result in 10mm depth
of inundation over approximately 40m2 of the basement floor.
A 1%AEP 2hr duration storm will deliver 157mm rainfall to the catchment with peak flows of around
0.6l/s. This will deliver, 3.8m3 of water to the sump for discharge by the pump. If the pump fails this
would result in 13mm depth of inundation across the basement floor (290m2). This is not
considered to be a significant threat to life or property and can be further contained with additional
grading of the basement slab in detail design phase. The development incorporates a battery room
in the basement. This battery will run the pump during a power failure.
The final location of the sump will be determined during the structural and details design phase
however the engineering drawings have been amended to show an outlet pipe provision to the
surface level stormwater pit adjacent to the southern boundary.
We trust that this additional information is acceptable to Council and look forward to approval of
the proposed work. If you have any questions regarding this response please contact me directly.
Yours Faithfully
