1 INTRODUCTION
This Site Based Stormwater Management Plan (SBSMP) has been prepared for the proposed
Townhouse Development at 101-105 Eumundi Noosa Road, Noosaville.
This SBSMP has been prepared to investigate the effects the development will have on stormwater
quantity and quality.
The objective of this SBSMP is to ensure that there is no adverse impact by the development on
the environmental value of the receiving waters during the construction and operational phases
of the development. This SBSMP will also provide recommendations to ensure that the post-
development peak outflow conditions are not greater than the pre-development peak outflow
conditions.
In order to achieve this objective, this SBSMP:
1. Describes the environmental setting of the development site and precinct;
2. Describes the nature of the proposed development as it relates to stormwater quality;
3. Calculates the peak flows for both pre and post-development conditions;
4. Calculates the detention volume required to achieve the pre-development outflow in the
post-development state; and
5. Identifies potential sources of contaminants and describes the management techniques
designed to be employed on the site to achieve the water quality objectives.
The proposed development has been assessed against the following guidelines and planning
documents:
1. State Planning Policy 2017 (SPP 2017);
2. Urban Stormwater Quality Planning Guidelines 2010;
3. The Queensland Urban Drainage Manual (QUDM); and
4. The Noosa Council Planning Scheme.

4 EXISTING DRAINAGE PATTERNS
4.1 Existing Infrastructure
Data obtained from the detailed survey and as-constructed information obtained from Noosa
Council’s interactive mapping show the following existing drainage infrastructure:
1. An existing 225mm to 450mm dia stormwater pipe running parallel to the south eastern
boundary of the site within Lots 45, 46 and 62 on SP132578 and Lots 42-44 on SP144002;
2. An existing gully pit located within the south east corner of the site with a 225mm dia.
stormwater connection to the existing 300 dia pipe within Lot 46 SP132578;
3. An existing stormwater structure located at the north-western corner of the site within the
driveway access of Lot 61 on RP69404, with a kerb adaptor connection to Eumundi Noosa
Road.
Refer to Figure 4.1 for the existing stormwater infrastructure and drainage patterns, Appendix A
for the Detailed Site Survey and Appendix C for the Noosa Council Interactive Mapping data.

4.2 Existing Drainage Patterns
Data obtained from Noosa Council’s records and detailed site survey indicate that the site has
the following drainage patterns:
Roofwater Runoff
1. The existing commercial building roofwater appears to travel underground and connect
into the existing structure located within the driveway access of Lot 61 on RP69404. Hence,
the roofwater from the existing commercial building was discharged to the Eumundi Noosa
Road kerb and channel.
2. A review of the street frontage of the site along Eumundi Noosa Road indicated that there
is no kerb outlet for Lot 1 on RP849431. Hence, it is assumed that roofwater from the
existing residential building is discharged to the ground or to the existing underground
stormwater infrastructure at the rear of the site via downpipes.
Surface Runoff
1. Surface runoff from the rear portion of Lot 1 on RP230931 generally sheet flows towards
the adjacent site on Lot 61 on RP69404, north and east of the site.
2. Surface runoff from the front portion of Lot 1 on RP230931 generally sheet flows towards
the Eumundi Noosa Road kerb and channel.
3. Surface runoff from Lot 1 on RP849431 generally sheet flows south east towards Lot 46 and
62 on SP132578.
External Catchment
1. There appears to be no external catchment entering the site.
4.3 Lawful Point of Discharge
If the proposed development maintains pre-development flow conditions, the lawful point of
discharge for the proposed development is the existing stormwater drainage infrastructure within
Lot 46 and 62 on SP132578, southeast of the site and the Eumundi Noosa Road kerb and channel.
In consideration of the site characteristics, surrounding topology and stormwater drainage
infrastructure, the aforementioned proposed lawful point of discharge is considered to be
compliant with the criteria for lawful point of discharge outlined in Section 3.9.1. of QUDM 2017
as per below:
i) The location of the proposed discharge point is under the lawful control of the local
government or other statutory authority from whom permission to discharge has been
received.
ii) The post development discharge will not cause an actionable nuisance, nor environmental
or property damage, as it is intended to implement measures to account for any change to
the existing flow characteristics.
iii) Authority to discharge over affected properties will not be required as the proposed
development will discharge directly into the existing waterway and will be maintained as
per existing drainage conditions.
Refer to Section 5 outlining the Stormwater Quantity aspects of this site and Appendix D for the
Water Quality and Drainage Code.

5 STORMWATER QUANTITY
A roof and allotment drainage system is to be designed to comply with:
1. AS/NZS 3500.3:2015 - Plumbing and Drainage Part 3: Stormwater Drainage;
2. The Queensland Urban Drainage Manual (QUDM), and;
3. The Noosa Council Engineering Design Standards – Roads, drainage and earthworks.
5.1 Rational Method Assessment
The Rational Method has been used to calculate the peak discharges from the site under the
existing (pre development) and proposed (post development) conditions.
5.1.1 Design Storms
As defined in the Noosa Council’s Planning Scheme the following design storms were adopted:
1. Minor Drainage System: 10 year ARI statistical flood (Q10 storm);
2. Major Drainage System: 100 year ARI statistical flood (Q100 storm).
5.1.2 Rainfall Intensity
Rainfall intensities for this study were obtained from the Australian Bureau of Meteorology.
5.1.3 Times of Concentration
Times of concentration (tc) were calculated as defined in the QUDM. Refer to Table 5-1 for the
adopted tc’s and Appendix E for tc calculations.
Table 5-1 – Adopted tc values

5.1.5 Peak Flows
Refer to Table 5-3 for a summary of the predicted minor and major discharge rates for pre and
post development conditions and Appendix E for the Rational Method calculations.

Post development C 0.020 0.024 0.036 0.045 0.054 0.066 0.073
The proposed development will result in an increase in impervious surface areas and will
consequently increase stormwater runoff peak flow rates in Catchments A and B.
Hence, it is proposed to utilise an on-site detention (OSD) system to mitigate the stormwater
runoff of the proposed development prior to discharging to the existing stormwater infrastructure
within Lot 46 and 62 on SP132578, southeast of the site.
Catchment C will result in a decrease in stormwater runoff peak flow rates. Therefore, no
detention is required to mitigate Catchment C. However, a rainwater reuse tank has been
proposed which will provide some mitigation.
Refer to Section 5.3 for the XPSTORM Modelling analysis of the site, Appendix E for the Stormwater
Quantity Calculations, Appendix F for the Concept Site Levels and Drainage Plan and Section 6 for
the Stormwater Quality Management Plan.
5.2 Proposed Drainage Patterns
The proposed drainage patterns are as follows (Refer to Appendix F):
Roof Catchment:
1. Runoff from the roof catchment of Townhouse Units 1-8 will flow via downpipes to a
rainwater tank located at the northwest corner of the site for rainwater reuse with
overflow discharging to the Lawful Point of Discharge within the Eumundi Noosa Road kerb
and channel.
2. Runoff from the roof catchment of the rest of the site will flow via downpipes an internal
drainage system, where it will be directed to the detention basin located at the southeast
corner of the site prior to discharge to the Lawful Point of Discharge within Lot 46 and 62
on SP132578.
Ground Catchment:
1. Surface runoff from the ground level hardstand and landscaping areas will be collected by
various stormwater pits connected to the internal drainage network, where it will be
directed to the detention basin located at the southeast corner of the site prior to
discharge to the Lawful Point of Discharge within Lot 46 and 62 on SP132578.
Refer to Appendix F for the Concept Site Levels and Drainage Plan.

5.3 Downstream Pipe Infrastructure Considerations
The existing 225 to 450mm diameter stormwater line traversing the rear of Lots 45, 46 and 62 on
SP132578 and Lots 42-44 on SP144002 has been modelled within PC DRAINS to determine its
capacity to take post-development mitigated flows from the development. The subsequent
longitudinal sections and calculations table have been exported from PC DRANS and outlined
within the drainage plans attached in Appendix F.
It was determined from the results of PC DRAINS modelling that the downstream stormwater
drainage infrastructure has capacity to convey up to 67L/s from the proposed development.
Subsequent XPSTORM detention modelling has taken this capacity into account.
5.4 XPSTORM Modelling
5.4.1 Intensity Frequency Distribution
The IFD data and temporal patterns used for the XPSTORM modelling has been obtained from the
Bureau of Meteorology for the following coordinates:
Latitude -26.406
Longitude 153.050
Refer to Appendix G for a copy of the BOM IFD data table.
5.4.2 Initial and Continuing Losses
Initial and continuing losses were approximated based on the storm losses obtained from ARR Data
Hub for the aforementioned coordinates. Refer to Table 5-4 below for the adopted initial and
continuing losses.
Table 5-4 – Adopted Initial and Continuing Losses
Designation Initial Loss Continuing Loss
Impervious Areas 0.0 0.0
Pervious Areas 25.0 2.5
5.4.3 On-site Detention
In order for the post-development stormwater discharge conditions to match the pre-development
conditions, it is proposed to incorporate an open detention basin with a maximum storage volume
of 254kL. The detention basin is to be located above ground within the southeast corner of the site.
The proposed OSD basin will have the following properties:
Specified base area = 223m2;
Specified internal depth = 1.15m;
Low flow orifice diameter = 0.14m;
Overflow weir pit elevation from base of tank = 1.03m;
Required basin volume = 230kL; and
Provided basin volume = 256kL.
Site Based Stormwater Management Plan
Proposed Townhouse Development at 101-105 Eumundi Noosa Road, Noosaville
Page 11
20169 - SBSMP/2
Page 11
The detention basin will be designed to contain all flows up to a Q20 storm event. Storm events
exceeding Q20 will be expected to sheet flow across the boundaries at or less than pre development
flows.
Refer to Appendix F for the Concept Site Levels and Drainage Plan which details the proposed on-
site detention system.
5.4.4 Comparison of Peak Flows at Lawful Point of Discharge
The pre-development and post-development mitigated peak mean/median flow rates were
compared for the catchment and are shown in Table 5-5 below.

The XPSTORM hydraulic modelling has demonstrated that the proposed mitigation implemented will
maintain pre-development flows (or less) for all design storms at the LPD located within Lot 46 and
62 on SP132578, southeast of the site. The modelling has also demonstrated that post-development
mitigated flows up to Q20 can be conveyed through the 225 to 450mm diameter stormwater line
traversing the rear of Lots 45, 46 and 62 on SP132578 and Lots 42-44 on SP144002.
Refer to Appendix H for the pre-development XPSTORM results, Appendix I for the post-
development XPSTORM results and Appendix J for the XPSTORM post-development mitigated
results.

6 STORMWATER QUALITY
The following section of the report will outline the potential contaminants and proposed solutions
to be incorporated during the construction and operational phases of the proposed development.
6.1 State Planning Policy Assessment
The purpose of this sub section is to determine if State Planning Policy (SPP 2017) stormwater
quality requirements, as set out by the Department of Environment and Resource Management, will
be triggered for this development. Refer to Table 6.1 for the State Planning Policy Checklist for
stormwater quality.
Table 6.1 – State Planning Policy Checklist
Material Change of Use (MCU) Y/N?
MCU for an urban purpose that involves premises ≥ 2500m 2 Y
AND
Will result in 6 or more dwellings
Y
OR
Will result in impervious area greater than 25% of the net developable area.
Y
The development has been assessed against the latest State Planning Policy 2017 (SPP 2017). The
proposed development will entail the material change of use for urban purposes, which will involve
a land area greater than 2,500m2. Consequently, State Planning Policy 2017 (SPP 2017) is triggered.
Hence, tertiary stormwater quality treatment is warranted for this development in accordance
with the State Planning Policy 2017 (SPP 2017).
6.2 Construction Phase
Sediment generated during the construction phase shall be dealt with in accordance with an
Erosion and Sediment Control Plan and kept on site during the construction phase.
Erosion and Sediment Control (ESC) Measures such as silt fences, diversion drains, drainage
structure protection and dust control (clearing) will be implemented. Silt fences are to be erected
along the boundary of the site and around the construction area. These fences are to be cleaned
by the contractor when the capacity is reduced by 25%. Where possible, disturbance to the existing
surface is to be limited to the immediate work area. The existing ground cover is not to be stripped
until the contractor is ready for earthworks to begin.
Stockpiles and construction materials are not permitted to be stored within the road reserve and
should be contained using silt fences. Diversion drains are to be provided at upstream catchments
to reduce flows to earthworks areas. In any areas where flows could enter adjacent properties
temporary stabilisation is to be provided.
All ESC measures are to be provided as soon as earthworks have commenced and staged to suit
construction. The contractor is responsible for this action. A temporary construction exit is to be
located at each entry point to the site and will be determined based on the stage of works being
completed. The contractor is to ensure all dust tracked onto surrounding roads is immediately swept
to remove silt/dust.
All new stormwater pits are to be protected from sediment infiltration by wrapping new pits and
grates in geofabric or covering appropriately with timber board. Silt fences are to remain in place
during the maintenance period until the site is established (80% ground cover).

6.3.2 Proposed Treatment Train
The proposed treatment train has been modelled using the following methodology:
1. Roofwater from Building 1 will be collected by a 15kL rainwater reuse tank with overflow to
the Eumundi Noosa Road kerb and channel.
2. Roofwater from the rest of the proposed development will be collected by the internal
drainage network which will subsequently direct flow to the end-of-line bio-retention basin
for treatment.
3. Surface runoff from the hardstand areas and landscaping areas will be collected by various
pits. The internal drainage networks will subsequently direct flow to the end-of-line bio-
retention basin for treatment.
All runoff described above will then discharge to the lawful point of discharge. A Concept Site
Levels and Drainage Plan of the proposed internal drainage network detailing the treatment train
assets is included in Appendix F. Refer to Table 6.5 for details of the proposed treatment train
assets.

6.3.3 Pollutant Export Modelling
Following the definition of water quality objectives for the site and an assessment of the treatment
options suitable for the development, the most appropriate treatment scheme for the site was
identified. The impact of the stormwater management strategy on the quality of stormwater runoff
discharged from the site has been assessed using the pollutant export model, Model for Urban
Stormwater Improvement Conceptualisation (MUSIC).
6.3.4 MUSIC Modelling Parameters
The MUSIC model was set up in accordance with the Water-By-Design MUSIC Modelling Guidelines
for South East Queensland to the parameters listed in Table 6.5 and Table 6.6. Refer to Figure 6.1
for source node areas.

Should operational requirements change, this plan is required to be amended to suit. Substantial
changes may require resubmission to the local authority. Following completion of construction, this
plan is to be incorporated into the total-site management practices.

Information from the Noosa Council Flood Hazard Overlay Map confirms that the site is unaffected
by flooding and inundation.
Refer to Appendix L for the Noosa Council Flood Hazard Overlay Map.

8 CONCLUSION
The proposed Townhouse Development at 101-105 Eumundi Noosa Road, Noosaville has been
assessed for its impact on the quantity and quality of stormwater drainage.
If the proposed development maintains pre-development drainage patterns, the lawful points of
discharge are the stormwater drainage infrastructure within Lot 46 and 62 on SP132578, southeast
of the site and the Eumundi Noosa Road kerb and channel, west of the site.
No external catchments have been identified.
Onsite detention will be provided in the form of a detention basin to attenuate post development
peak flow rates and ensure non-worsening of flooding to properties and infrastructure adjacent to,
and downstream of the subject site. The detention basin will be designed to contain all flows up to
a Q20 storm event. Storm events exceeding Q20 will be expected to sheet flow across the
boundaries at or less than pre development flows. The volume and configuration of the on-site
detention system will be confirmed during detailed design stage.
Sediment generated during the construction phase shall be dealt with in accordance with an
Erosion and Sediment Control Plan to be kept on site during the construction phase.
The proposed development triggers the State Planning Policy 2017 (SPP 2017). The water quality
objectives (WQO’s) for South East Queensland have therefore been achieved by treating the roof
and surface stormwater runoff via a bio-retention basin and a rainwater tank for rainwater reuse,
prior to discharging to the Lawful Points of Discharge.
The subject site is not affected by flooding.
