1. Introduction
vT Consulting Engineers has been commissioned by Verve Building Design & Concepts to
prepare this engineering services report and stormwater management plan. The development
is located at 3 Garnet Street, Cooroy QLD 4563 (Lot 14 on RP845961). The site locality is
illustrated in Figure1.1. This report is being submitted to support the Development Approval
for the proposed Supermarket Development for Noosa Regional Council’s (NRC)
consideration.
The following report will detail civil engineering requirements for the development.

By: MRS Revision No.: C
a. Existing Topography
The site is currently developed, accommodating several sheds, a low-set timber house and
concrete paving, covering a total of approximately 91% of the site. The balance of the site
(277m2) is landscaped with a mixture of turf, paving and several medium sized trees.
The site grades evenly from a level of approximately RL115.0 in the south east corner on
Garnet Street down to approximately RL111.5 in the north west corner in Wimmer’s Lane to
the rear. A detailed survey has been conducted on this site by Saunders Havill Group Pty Ltd,
dated 20 March 2015. Refer to Appendix A for current survey plan. The site is bounded by
commercial buildings with a hotel complex opposite in Garnet Street. A residential dwelling
exists to rear of the western neighbouring property entering on to Wimmer’s Lane at the rear.
b. Proposed Land Use
The proposed development involves a new supermarket development and associated car
parking (including basement).
Refer attached Appendix B for proposed layout plans and details.
2. Erosion and Sediment Control
Using the Noosa Sediment and Erosion Control Assessment form in Appendix C, it is
considered that the erosion risk proposed by the site is low as the proposed development
involves an area of land which will only be exposed for a minimal amount of time during the
earthworks required for service trenching and constructing the building basement, platform
and car-parking. The trenches will only be exposed while the services are being installed and
then will be covered by the proposed building works. To further mitigate the impact of the
development construction an Erosion and Sediment Control Plan has been prepared and is
included in Appendix B. Appendix D shows the International Erosion Control Association
Australasia standard drawings and control notes applicable to this development.
The construction contractor is responsible for ensuring that soil and debris does not leave the
site as well as the confines of the construction zone and is not deposited on external roads or
existing in-use areas due to the proposed earthworks and construction activity.
Acid Sulphate Soils
The local council is listed in Table 4: Acid sulphate soils-affected local government areas in
State Planning Policy April 2016 (SPP 2016) and therefore this development application
requires compliance with the SPP 2016 acid sulphate soils development objectives.
Acid sulphate soil testing is typically conducted in areas with reduced levels of less than 5.0m
Australian Height Datum (AHD) as stated in SPP 2016. This policy also states that
developments below 20.0m AHD that involve a Material Change of Use or operational works

are required to be assessed against the SPP 2016 acid sulphate soils development objectives.
As the lowest point on this site is an approximate level of RL111.5m, we believe the
probability of acid sulphate soil being present is low and therefore testing would not be
necessary.
The requirements for Acid Sulphate Testing will be confirmed by a geotechnical engineer prior
to the detailed design stage of this proposed development.
Land Disturbing Activities
Important causes/issues of erosion for this site would consist of the following:
Precipitation and consequent run-off
Stripping and removal of topsoil
Removal of fill
Other earthwork operations
Heavy vehicle use on site
Wind erosion
The proposed development is a short construction period which will be programmed so that
the shortest period of time elapses between ground cover removal and restoration.
Erosion and Sediment Control Measures
Sediment control filter fabric will be securely placed around the perimeter of the construction
site. This will ensure sediment is trapped before being released into the catchment. Refer
Appendix D.
An ESC measure will be provided at any vehicular access points to the site. Construction and
maintenance details are given in Appendix D. A temporary construction entrance will be
provided from Garnet Street for access during construction.
A filter sock sediment trap will be utilized on all downstream stormwater inlets. Refer
Appendix D for construction and maintenance details.
No clearing will be undertaken unless preceded or accompanied by installation of adequate
run-off and sediment control measures, as described above.
Following practical completion of the project a minimum of 70% coverage of all soil with
ground cover (i.e. topsoiling and seeding) will be provided within 30 calendar days.
During the construction phase spraying of water will be used with care to act as a dust
suppression method.
Monitoring and Maintenance Programs
Water discharge from the site will adhere to a total suspended solid content of less than 50
milligrams per litre and a pH range of between 6.5 and 8.5 at all times. If the pH of the

flocculated water is not achieved than pH adjustments will be required. This could possibly be
done by a dosing of lime.
Site personnel will inspect all erosion and control measures at least at the following
frequencies:
Daily during construction works,
Weekly when construction works are not happening,
Within 24 hours of expected rain, and
Within 18 hours of an impacting rainfall event.
All erosion and sediment control measures that have an order of efficiency below 75% will be
corrected by the end of that working day.
Staging of ESC Measures
The design of the proposed erosion and sediment control treatment devices is to be
confirmed during detailed design and following confirmation of the construction sequences
for the development. The proposed treatment measures will be designed in accordance with
the International Erosion Control Association Australasia standards and standard drawings to
ensure that the proposed works minimise any impact on the downstream water quality.
3. Earthworks
For the purpose of this proposed development earthworks will be conducted for constructing
the new proposed building basement, platform and carparks. Excavation on site will be
required for the building basement, platform and service trenches. Any excess cut will need
to be removed from the site by the contractor.
A geotechnical investigation will be undertaken and a report will be prepared for the site prior
to starting the detailed design stage of the development to ensure that the earthworks and
erosion control measures are designed to suit the site conditions.
4. Roadworks
The proposed development fronts onto both Garnet Street and Wimmer’s Lane. Road works
will be limited to line-marking and crossovers.
5. Stormwater Drainage
As indicated by Cooroy & Lake Macdonald Natural Resources Overlay (Map OM3.5 (Part))
shown below, the site is located outside the Lake Macdonald water supply catchment.

Site
Figure 5.1: Lake Macdonald Water Supply Catchment Adjacent to Site
The site currently hosts a stormwater easement for a 525 diameter pipe which traverses from
Garnet Street to Wimmer’s Lane at the rear. It is proposed to upgrade this pipe to 750
diameter and reroute it around the proposed building, to the vicinity of the existing sewer line
through the property and back to the existing manhole in Wimmer’s Lane. It is anticipated
that this will require 2 sag gullies in Garnet Street to accommodate the capture of surface
stormwater flow from a Q100 event. Calculations are shown in Appendix G.
a. Stormwater Quality Management
State Planning Policy
The State Planning Policy April 2016 applies for stormwater quality management and
management of new or expanded non-tidal artificial waterways applies to development that is

stormwater treatment measures for the proposed development. Selection and testing of
stormwater management options was undertaken in accordance with MUSIC Modelling
Guidelines prepared by Water by Design (2010).
The MUSIC model was set up using the site catchment area which was further split to include
roof areas, road areas and ground areas in accordance with the MUSIC Modelling Guidelines
prepared by Water by Design (2010).
The stormwater quality treatment train used in the MUSIC model is shown in the figure below.

used if the alternative product does become approved for use. Based on these discussions it is
assumed that subject to their approval, council may accept a change in the proprietary
product used.
d. MUSIC Model Results
Using the MUSIC software the treatment train for the catchment areas was designed to
comply with the water quality objectives (WQO). It was determined that the water quality
objectives for the proposed development where met as shown in the table below:

Table 5.5: Stormwater360 Water Quality Treatment Results
As shown by the above results, the proposed stormwater treatment train adopts best practice
stormwater treatment and will achieve the required Water Quality Objectives.
e. Stormwater Quantity Management
Noosa Regional Council Policy requires that a development ensure non-worsening of
stormwater flows up to and including Q100 stormwater events. The proposed development
will not have a larger impervious area than the existing developed site and hence will not
require a stormwater detention system to mitigate the effects of any additional runoff.
f. Maintenance
Construction Phase Management Plan
Potential construction phase impacts include the following:
Sedimentation and erosion
Management of contaminated soils and materials on the site Construction Material (such
as cement)
General
The objective of the Construction Phase Management Plan is to comply with the requirements
of the Queensland Environmental Protection Act 1994 and Environmental Protection (Water)
Policy 2009 so that the environmental values of effected receiving waters are maintained or

enhanced. In essence the purpose of the Plan is to prevent polluted stormwater being
discharged to the local waterways.
Performance Indicators
The management is not being effective when any of the following occur during the
construction phase of the project.
The required water quality objectives are not achieved,
Contaminated water is released off site.
Construction Phase Management of Sedimentation and Erosion
A sediment and siltation fence will be erected around the property boundary to ensure that
sediment is not washed off site and onto adjacent properties or roads. Entry and exit from
the site will be restricted to a single stabilised location to minimise the rise of onsite transport
of silt sediment or mud. It is anticipated that a layer of crushed rock will provide the
necessary stabilisation of the access route. If required a specific bunded wash down area will
be provided for the cleaning of plant before leaving the site and all wash down waste water
will be collected. In the event that debris or sediment leaves the site it will be cleaned.
Management of Contaminated Soils Materials
There are no contaminated soils materials fill on the site. The site is not listed on the public
contaminated site’s register.
Management of Imported Materials
Any material imported to the site including construction materials will be stockpiled in a
location where it cannot contaminate the stormwater system or stormwater runoff.
Complaint Response
The contractor will erect signage at the entrance to the works with contact information,
including afterhours contact numbers. The contractor will properly deal with all complaints.
Monitoring and Reporting
All sediment and erosion control devices will be checked daily and after rainfall events by the
construction site supervisor. Defective or full devices will be cleaned and repaired as
required. Regular inspections and maintenance of the storm water system will be carried out
by the property owner. The civil components (structural and erosion) are to be assessed by a
suitably qualified engineer as required.
Lifecycle cost assessment
There will be no abnormal capital or recurrent costs for the proposed stormwater strategy.

NOTES
This Plan has been prepared from a combination of field survey
and existing records for the purpose of showing the physical
features of the land to assist in designing future development, and
should not be used for any other purpose.
The title boundaries shown hereon were not verified or marked at
the time of survey, but were determined by existing title
dimensions and occupation (where available), not by field
measurement. As such, these dimensions could be out of date
and incorrect by modern standards. This plan should not be used
for building to boundary, or to prescribed set-backs, without further
boundary survey.
Services shown hereon were located where possible by field
survey. If not able to be so located, known services have been
shown from the records of the relevant authorities or service
providers where available and have been noted accordingly on
this plan. All services shown by records only will need verification
prior to, or during work on site.
Prior to any demolition, excavation or construction on site, the
relevant authority should be contacted for:
* Verification of all services plotted from records only, and
* Possible location of any services altered since this survey was
completed or any new services installed either on or adjacent to
the site.
Before starting any demolition, excavation or construction on
the site, the relevant person should make an independent and
updated enquiry of "dial before you dig" and any relevant
service providers to ascertain the existence of further
services (if any) and the accurate location of those not able to
have been surveyed at the time of preparing this plan.
* No responsibility can be accepted by Saunders Havill Group Pty
Ltd, for any damage caused to any underground service or any
loss or injury so suffered if enquiry and verification have not been
completed in accordance with this note.
** This note is an integral part of this plan/data. Reproduction of
this plan or any part of it without this note being included in full will
