1.0 INTRODUCTION
This report is lodged in support of a Minor Change application to Noosa
Council seeking to develop residential unit buildings at Lot 9 SP195871,
Serenity Close, Noosa Heads.
The proposed development represents the fourth stage of residential unit
buildings developed by Cape Bouvard over the greater Settlers Cove site with
Alta Projects’ engineers having completed stormwater design, inspection and
certification for all previous stages.
Design solutions presented in this report are consistent with those previously
adopted with minor refinements borne of experience.
1. In particular, this report addresses stormwater management issues
raised, at conditions 41 to 45 of Material Change of Use Decision
Notice 132008.175.03 dated 6 August 2019.
41. A stormwater management plan shall be prepared by a RPEQ,
specialising in stormwater and water quality management incorporating the
principles of the Environmental Management Plan for the Settlers Cove
Development (23118 DA), that demonstrates water
reuse strategies, infrastructure capacity and effective treatment methodology.
The use of rainwater harvesting tanks for irrigation purposes shall be
incorporated in the overall design plans. These plans shall be submitted to
Council for approval prior to obtaining a
Development Permit for Operational Works.
` 42. Roof runoff from any new building should be directed to a rainwater
storage system or tank (minimum 23,000 litres) that is installed to ensure
water from the rainwater storage system or tank is used for external uses
(such as watering gardens, irrigation, ornamental ponds, water features,
topping-up swimming pools, outdoor cleaning, etc) and for internal (ground
floor) use in washing machine cold taps and toilet cisterns. All rainwater tanks
are to be designed and installed in accordance with the approved Stormwater
and Water Quality Management Plan and the Queensland Development
Code (QDC) current at the time of building approval, and shall be part of the
plumbing application for approval. The location and capacity of the tanks shall
be clearly shown on the plans submitted for Building Works/Operational
Works approval and any overflow shall be directed to the stormwater
drainage system.
43. All stormwater drainage shall be collected on site and discharged so there
is no net increase in stormwater runoff from the site.
44. To ensure that polluted run-off does not enter the water table, the
adjoining waterways or Council’s stormwater drainage system, stormwater
run-off from the car parking areas and the driveways shall have the first flush
(the first 12mm of rainfall or hose-down) collected in

Section 4
a grease/oil arrestor/gross pollutant trap provided on site prior to being
permitted to discharge into the larger drainage system. All other clean
stormwater, such as roof water, can be collected on site and discharged
through a single underground drain line directly into the existing drainage
system, bypassing the grease/oil arrestor/gross pollutant trap. To this end, a
detailed maintenance plan shall be prepared for the proposed grease/oil
arrestors/gross pollutant trap, which shall be submitted to the Council for
approval prior to obtaining a Development Permit for Operational Works. The
approved maintenance plan shall be incorporated in the Community
Management Scheme for the development and a copy of this shall be
provided for Council’s records prior to commencement of the approved Use.
A Development Permit for Building Works shall not be granted until a
Development Permit for Operational Works has been issued in regard to the
drainage scheme.
45. All site stormwater drainage shall be by means of a gravity system.
2.0 EXISTING CONDITIONS
The subject site is currently undeveloped and generally supports only grasses
and sucker regrowth.
The site falls at moderate grades away from a ridge near Serenity Close
towards Private Open Space for Conservation and Waterway Protection
(POSCWP) areas to the west.
An existing boulder retaining wall along the sites western boundary separates
the development site from POSCWP areas and the adjacent access pathway to
Noosa Inlet.
The entire site consists of loose, poorly graded dune sand and as such
contains no defined overland drainage paths since rainwater infiltrates
directly through the permeable surface.
Refer detail survey at Appendix E.
3.0 PROPOSED DEVELOPMENT
The proposed development is to consist of two (2) multi storey residential
buildings with a basement carparking under and a shared driveway
arrangement. Each building is to be surrounded by extensive terraced
landscape areas, both hard and soft.

Section 5
4.0 STORMWATER TREATMENT & DISPOSAL
Treatment and disposal of runoff will be carried out in accordance with the
approved document Settlers Cove Noosa Residential High Density Environmental
Management Plan (EMP 1) by WBM Oceanics Australia.
Alta Projects engineers (formally TATE) were involved in formulation of the
overarching development approval document and EMP1 produced by WBM
Oceanics.
EMP1 recognises in particular the regimes of stormwater runoff and
infiltration which existed over the broader RHD site pre-development.
Essentially it was recognised that the RHD site lies atop a dune of poorly
graded sand with particularly high rainfall infiltration rates. As such the
natural state sees all rainfall for events up to 10 year ARI infiltrate the dune
close to where it lands and replenish the water table below with little or no
runoff.
The standing water table forms a profile similar to the shape of the dune,
albeit at a depressed scale and emerges as seepage flows adjacent Noosa inlet
at or about RL 5.0m.
The zone between RL 5.0m and the inlet was recognised as having
particularly high ecological values, supporting numerous stands of swamp
mahogany and various species of fauna. Critically it was recognised that
these ecological values were dependant on maintenance of the natural
hydrogeological regime and no nett reduction in rainwater infiltration post-
development.
Consequently, and in order to counteract the effect of significant impervious
areas being constructed, the design approach will see stormwater runoff from
roofs and hardstand areas, up to 100-year ARI infiltrated into the natural
sands via a series of Rapid Infiltration Pits (RIPs) in order to achieve no net
reduction in rainwater infiltration.
Driveway and carpark areas will be passed through a GPT/oil arrester to
remove oils and hydrocarbons prior to infiltration.
Main roofed areas from both buildings will drain to a Rainwater Harvesting
Tank with captured runoff utilized for landscape irrigation. Tank overflow
will be directed to catchment specific RIPs.

Section 6
Runoff from main landscaped areas will be intercepted and conveyed via a
landscaped swale located along the site’s western boundary to a series of RIPs
and shallow landscaped basin at the south-western corner of the site.
RIPs will be aggregated within the basin and flows greater than the 1% AEP
major design event will be directed toward the POSCWPas dispersed sheet
flow via a broad weir.
Refer to engineering drawings at Appendix A for details.
5.0 RAPID INFILTRATION PITS (RIP’s)
RIPs consist of a bottomless stormwater pit which promotes infiltration
through its base.
Crushed rock and multiple layers of geofabric and “sacrificial sand” are
installed at the base of the RIP to protect against clogging of dune sands
below.
RIPs are subject to routine inspection and maintenance by the building’s body
corporate and such maintenance is critical to their ongoing function. (refer
Maintenance Schedule at Appendix B).
RIPs have been installed on all previous stages of Settlers Cove and proven to
work very well.
Refer engineering drawings at Appendix A for RIP details.
6.0 CALCULATIONS
6.1 RIP Infiltration (100year ARI events)
Alta Projects engineers (formally Tate) were involved in
formulation of the over-arching development approval
document and EMP1.
Such involvement included construction of a prototype RIP on
the Settlers Cove site and field testing to determine infiltration
rates. Results were consistent indicating a liner relationship
between driving head and infiltration rate such that:
__________________________________________________________________________
A6107/L9/SMP/RevA/Aug 2021 Page 4 of 7
SH/pl
Brah101 Pty Ltd t/as ALTA PROJECTS
Section 7
Infiltration Rate (mm/s) = 4mm/sec + 13.6 x head (m)
Refer to Appendix C for prototype test results.
In order to model the operation of the RIP’s, a spreadsheet has
been developed and utilised for all previous stages of Settlers
Cove.
Temporal patterns for Zone 3 from the Australian Rainfall and
Runoff, Volume 2 were applied. These temporal patterns were
used in conjunction with the average rainfall intensities for the
Noosa region to create a series of design storms of varying
duration for a 100-year average return interval (ARI).
Temporal patterns were converted to flow rates by breaking
each storm event into a series of short duration storms. A
triangular flow verses time approximation was used for each
sub storm with sub storm flows then added to produce flow Vs
time for RIP inflow.
Outflow and water depth were then calculated through
iterations for the duration of the storm based on the infiltration
rate / head relationship discussed above. A factor of safety of
2.0 was applied to the observed prototype infiltration rate. Each
RIP was then sized to prevent overtopping in a 100-year ARI
storm event of any duration.
Spreadsheet model results for each building are attached in
Appendix D.
6.2 Emergency Overflow (>100year ARI events)
Emergency overflow, for events (>Q100) which cannot be
wholly infiltrated by RIPs, is to be directed to the POSCWP area
as controlled sheet flow at velocities/depths which will not
induce significant scouring.
In order to achieve this outcome RIP’s are to be aggregated in
discrete basins adjacent the POSCWP areas and behind existing
boulder retaining walls. Stone pitched weirs 3m long and at a
constant height 0.2m below surrounding bunded area will
control emergency overflow into the POSCW. The rough nature
__________________________________________________________________________

SH/pl

Section 8
of the stone pitching will also provide an “energy dissipation”
effect.
The following calculations demonstrate adequacy for lot 9: -
Running the RIP spreadsheet for 100year ARI storm of 5-minute
duration we note the following (refer Appendix D)
Qi (max) = 355 L/s at 5-minutes.
We also note that this corresponds with an available head of
3.2m (weir height above base of RIP’s) and an infiltration rate
through the RIP’s of: -
Maximum discharge outflow Qo (2.77m) = 245 L/s
Hence emergency overflow via the weir will not engage for
events <Q100 and will be contained within the designated RIP
system.
