1 INTRODUCTION
1.1 Background
Bligh Tanner Pty Ltd was commissioned by RPS Project Management c/- Lutheran Services to prepare
this site based stormwater management plan for the proposed Cooroy Care Farm project at 10 & 22
Rose Gum Road and 521 Elm Street, Black Mountain, Cooroy.
The purpose of this site based stormwater management plan is to support a Development Approval
submission. It describes the stormwater strategy for the site and considers erosion and sediment control
and stormwater management (water quality and hydrology).
This stormwater management plan has been prepared in accordance with the requirements for Site
Based Stormwater Management Plans as outlined in the State Planning Policy and Noosa City
Council’s CityPlan.
Key details about the site are listed in Table 1 below.

1.2 Locality Plan
The site is located approximately 4 km due northwest of Cooroy City Centre at 10 & 22 Rose Gum Road
and 521 Elm Street, Black Mountain, Cooroy Q4563. The site fronts on to Elm St and Rose Gum Road.
The eastern side of the site is Yurol State Forest and the west is private property. North of Rose Gum
Road is a railway corridor.
The southern side of the site is bordered by the Bruce Highway. The area proposed for development is
confined by the riparian zone associated with the existing creek through the site.
The site location is shown in Figure 1 below.

2 THE SITE
2.1 Proposed development
RPS, BVN and the design team have developed a masterplan for the Cooroy Care Farm development.
The proposed development consists of a multi staged development for an 80-100 bed facility comprising
of dementia care, transitional care and a respite facility. The current masterplan is included in Appendix
A. The project will be delivered in stages although these are yet to be fully defined. Please refer to
indicative staging in Appendix B.
2.2 Existing and Surrounding Land Use
The site consists of three large rural lots with small self-sufficient houses. There is a railway corridor to
the north and Bruce Highway to the south, however it is anticipated that the site will not impact either of
these assets.
2.3 Topography
The site is generally steep with grades mostly between 10-15%. The site is partially located at the crest
of the road and falls to the creek/gully at the rear of the properties. The highest point of the site is 126m
AHD, and falls away to 111m AHD at the back of the site. There is an existing dam with an overflow
spill point in the centre of the site and a further minor gully in the SE corner. Survey of the site is
included in Appendix C.
2.4 Existing Services
There are currently no existing services on site. Existing lots are self-sufficient
2.5 Vegetation
The site is mostly clear of undergrowth with larger trees remaining. The majority of vegetation is located
around the existing creek/gullies which run through the site. The proposed development will retain, as
far as practical, existing vegetation.
2.6 Soils
No information on site soils was available at the time of writing. A detailed geotechnical investigation
would be completed as part of detail design.
2.7 Flooding
The entry to the site is on a ridgeline and is not subjected to flooding from adjacent lands. The rear of
the building footprint appears to be set back from the creek corridor and outside of the available Noosa
City Council flood mapping extents.

3 STORMWATER MANAGEMENT STRATEGY
3.1 Existing Drainage and Legal Point of Discharge
The site forms part of the Lake McDonald catchment.
Dial Before You Dig, Council records (Noosa City Council IntraMaps), survey data and site records
indicate that there is no piped stormwater drainage system through the site. Given there is no potable
water service, the drainage for the existing houses is presumed to be via rainwater tanks before
discharging to the rear of the site.
It is considered that the legal point of discharge of the site is the existing creek at the rear of the site.
Two smaller gullies currently run through the site as per Appendix D and are considered the appropriate
stormwater discharge points. Catchments (at the development boundary) are calculated to be 2.9ha and
0.9ha for the western and eastern gullies respectively.
3.2 Stormwater Quantity Strategy
It is estimated that the fraction impervious of the site would increase from 5-10% up to 50% after the
proposed development (7.5 ha total development area). This increase would generate an increase of
stormwater runoff discharge from the site. To mitigate the possible adverse impacts created by this
runoff increase, some form of flow control / detention would need to be implemented.
Based on an analysis using the probabilistic rational method (QUDM 2013), the current peak site
discharge under a 1% AEP storm event is estimated to be 3.4 m³/s, and the 20% AEP site discharge is
2.3 m³/s.
The development should ensure that there is no change to these peak flows resulting from increased
impervious surfaces and more efficient drainage systems, however given the site’s location in relation to
the waterway at the rear of the site, the requirement for stormwater detention needs to be explored
further in liaison with the local authorities.
As the architectural and landscape design is still in development at the time of preparing this report, the
detailed design of the stormwater system will occur in due course. It is recommended that water
management be incorporated into the architectural and landscape design, potentially in the form of:
▪ Rainwater tanks
▪ Permeable pavement/surfaces
▪ Landscaping which slows and detains runoff.
▪ Integrated water management
The grade and vegetated nature of the site lends itself to use of swales/surface stormwater
management to maximise the amenity and environmental sustainability.
3.3 Stormwater Quality Strategy
The site is greater than 2500 m² in area. As such, it is above the threshold in the State Planning Policy
(SPP) for requiring compliance with stormwater quality provisions.
There are likely some simple and effective ways that the development might be able to minimise
impacts on stormwater quality while enhancing the amenity of the development, including the use of
permeable paving, using self-watering street trees along the road frontages, and directing roof and
pavement runoff into gardens and landscape areas.
During the detailed design stage, sufficient detail will need to be provided to demonstrate that the
proposed development works comply with the SPP requirements. The pollutant target objectives are
summarised in Table 2 below.

RPS Project Management c/- Lutheran Services Page 5 of 10
PF80 - Cooroy Care Farm
28 May 2018 Ref. No. 2017.0616
Table 2 Water Quality Pollutant Targets
Indicator Objective
Total Suspended Solids (TSS) 80% reduction in average annual load of pollutants leaving the
developed unmitigated scenario compared to the developed mitigated
scenario
Total Phosphorus (TP) 60% reduction in average annual load of pollutants leaving the
developed unmitigated scenario, compared to the developed mitigated
scenario
Total Nitrogen (TN) 45% reduction in average annual load of pollutants leaving the
developed unmitigated scenario, compared to the developed mitigated
scenario
Gross Pollutant 90% reduction in average annual load of pollutants leaving the
developed unmitigated scenario, compared to the developed mitigated
scenario
Based on the Deemed to Comply solutions in the State Planning Policy the total area designated for
vegetated stormwater treatment devices would be in the order of 1.5% of the 7.5ha development
(approx. 1,125sqm), although this figure is likely to be considerably reduced through the utilisation the
strategies listed above.
3.4 Stormwater Harvesting
Stormwater harvesting is anticipated to occur through the use of rainwater tanks and the existing dam.
Rainwater tanks will provide the majority of potable water requirements for the site and the existing dam
is expected to meet the non-potable water needs. The catchment to the existing dam is approximately
1.7ha. Refer to Appendix D for catchment details.
For further details refer to the engineering services report titled, “PF80- Cooroy Care Farm, Water
Supply & Wastewater Servicing dated 25th October 2017”.
3.5 Bruce Highway Hydraulic Analysis
The Bruce Highway Hydraulic Analysis Report (September 2010) prepared for Department of Transport
and Main Roads by GHD indicates that the Bruce Highway overtops in larger rainfall event with the
possibility to restrict access to the site in the Probable Maximum Precipitation Design Flood (PMPDF).
The key findings of the report relevant to our site are as follows:
• The Bruce Highway road shoulder (RL 117.5) will likely overtop to a depth of approximately
0.6m ( RL 118.07) in the Extreme Event (Probable Maximum Precipitation Design Flood
PMPDF)
• The properties above the highway (along Blueberry Drive) are likely flood affected at RL 113-
115. There is no mention of downstream properties being affected in the report.
• No overtopping of the highway is noted in storms up to the 100yr ARI storms (RL 112.13 max.
i.e. 5m freeboard below the road shoulder)
• There is access in a north direction along the Bruce Highway in all events.
A copy of the GHD Hydraulic Analysis can be provided on request.

28 May 2018 Ref. No. 2017.0616
Figure 2: Location of Flood Heights Referenced in GHD Hydraulic Analysis
3.6 Overland Flow from Dam
It is anticipated that there will be a requirement for an area above and below the dam to allow for a
swale/channel to convey the overland flows in larger rainfall events. Preliminary calculations show that
these swales would be in the vicinity of 4.5m to 6.0m wide for above and below respectively at a depth
of approximately 350mm.
The Palliative Care Building is currently located within this overland flow path so it is intended that the
existing channel will be required to be diverted away from the building.
3.7 DRNME Response -Taking or Interfering with Water
The conditions received from DRNME state that the stormwater connections do have the potential to
trigger the requirement for a water licence to be obtained.
Since it is expected that the connection works are minor in nature, they may be able to be undertaken
using the Riverine Protection Permit Exemption Requirements.
This will confirmed during the detailed design stage when the layout and quantity of earthworks/clearing
is further resolved.

3.8 Erosion and Sediment Control Practices
Stormwater run-off from land development and infrastructure development sites has a high potential to
cause water contamination and/or environmental harm. This is regulated under the EP Act 1994.
Under S440ZG it is an offence to unlawfully deposit a prescribed water contaminant to waters.
Prescribed contaminants are listed in Schedule 9 of the Environmental Protection Regulation 2008 (EP
Reg), and include: ashes, clay, gravel, sediment, stones and similar organic or inorganic matter, as well
as building and construction materials and waste.
Under S 319 persons in Queensland carrying out activities which may cause environmental harm must
comply with the ’general environmental duty’ (GED). This requires that all reasonable and practicable
measures must be adopted to prevent and minimise environmental harm. Although not being able to
demonstrate compliance against GED is not an offence, demonstrating that all reasonable and
practicable measures have been adopted is a defence for offences such as water contamination. For
instance, under chapter 10, s493A of the EP Act, where a person deposits a prescribed water
contaminant to waters or causes unlawful environmental harm, it is a defence to demonstrate
compliance with the GED. Demonstrating that all reasonable and practicable measures have been
conceived and implemented should encompass:
▪ thorough and ongoing site assessments
▪ consideration of, and adaptation for site specific erosion risk factors including topography, soil
type, climate and season
▪ design, installation, operation, management, maintenance and monitoring of control measures
as identified in the erosion and sediment control plan.
3.9 Erosion and Sediment Control Strategy
Erosion and sediment control will be addressed in detail prior to the construction stage. Best
management practices will be adopted and key elements of the erosion and sediment control strategy
will include:
▪ Minimising the duration of disturbance
▪ Close site supervision and inspection of ESC measures
▪ Sediment management using:
− Filter fences and sediment fences
− Sediment basins
− Dust/erosion suppressant polymers
− Regular use of water truck
− Controlled stockpile, entry and exit points.

4 CONCLUSIONS & RECOMMENDATIONS
▪ The development site is not affected by flooding from any source however there are several
existing overland flow paths which run through the site.
▪ The Bruce Highway Hydraulic Analysis prepared by GHD for DTMR indicates that the highway
has safe egress in all rainfall events up to the 1% AEP with overtopping only expected in the
PMPDF. In the event of this extremely rare flooding safe egress is available along the Bruce
Highway in a northerly direction.
▪ The Legal Point of Discharge for the Site is to the existing creek/gully at the rear of the site
▪ Stormwater quality management is proposed, given the site is above the 2500 m 2 threshold in
the State Planning Policy SPP Code: Water Quality.
▪ The development would need to implement a flow control / detention strategy to mitigate the
possible runoff increase generated by the works.
▪ A detailed Erosion and Sediment Control Plan would be required to be implemented for
construction.
▪ The vegetated and sloping nature of the site suggests the use of swales to maximize amenity
and environmental sustainability

5 FUTURE CONSIDERATIONS
Once the landscape and architectural plans are further resolved, the next steps to progress the
stormwater strategy are to consider the following items (addressed at a high level in this report) in more
detail:
▪ Determine preferred discharge points
▪ Assess catchments
▪ Assess areas for stormwater reuse/harvesting
▪ Calculate stormwater detention volume requirements
▪ Calculate stormwater treatment requirements
▪ Complete preliminary design of stormwater network
