1.0 Introduction
Backer
This Environmental Management Plan (EMP) has been prepared on behalf of Contrast Constructions Pty Ltd
to manage potential environmental impacts in relation to the approved redevelopment of the Peregian Beach
Caravan Park located at 215-219 David Low Way, Peregian.
The approved development involves the upgrading of the current tourist accommodation facilities by
constructing commercial buildings (restaurant/retail/offices) and accommodation units and beach shacks to
replace the current caravan park. The development also incorporates an approximately 20m service and
buffer area to the adjacent Noosa National Park.
As a condition of approval, an EMP is to be prepared that outlines management strategies to implement
during the construction and operational phase of the development to reduce the risk of environmental harm.
This EMP has been developed with general reference to the following:
Ecological Assessment, June 2007 by Natural Solutions;
Stormwater Management Plan / Sediment and Erosion Control Plan, December 2010 by Simmonds &
Bristow;
Ecological Restoration Plan, June 2010 by RPS;

pment Approval
The preparation of the EMP is in response to Condition 69-71 of the Development Approval for a
Reconfiguration of a Lot (ROL) application for the site, issued by the Sunshine Coast Regional Council
(SCRC). The prepared EMP is to address relevant environmental issues in relation to the construction and
operational phase of the development.
Construction and operational works for the approved development need to be undertaken in accordance with
the EMP to ensure the development's impact on the environment is minimal, the environmental values of the
site are protected and enhance, and the development is ecologically sustainable.
Statutory Obligations
In addition to the condition requirements outlined in the Development Approval for the site, the development
has obligations and responsibilities under numerous pieces of legislation and policies at the federal, state
and local levels. The EMP has been prepared to assist the development in meeting these obligations. Table

5. At the completion of the investigation, the Site Manager shall notify the complainant and Council in
writing of the results of the investigation and, if necessary, the nature and timing of any proposed
mitigation measures.
The Site Manager shall ensure that the Complaints Log is completed and all supporting documentation and
correspondence (e.g. initial complaint, complainant acknowledgement, complaint investigation report and
complainant notification etc) is retained.
& Data Management
Reporting will be required during the construction and operational phase of the development with specific
reporting requirements detailed further for each EMP element. Generally, reports must be kept of the key
environmental performance indicators, monitoring results, corrective actions, environmental incidents and
complaints, reports to management, and any reports required by law such as regulated waste tracking.
Any record or document required as an outcome of this EMP or issued by a regulatory authority must be
kept at the site office / Contrast constructions pty ltd Property office for a period of 5 years, and be available
to an authorised person. Any daily and weekly records or logs must be kept for a period of 3 years and are
then kept in the form of an annual summary after that period.
The site shall undergo regular audits to assess the compliance of management techniques as required under
this EMP. Frequency of audits is further detailed for each EMP element. The audit shall be undertaken by
an independent Environmental Officer and reports shall be submitted to the Site Manager and forwarded to
SCRC, as appropriate.
Environmental audits are to confirm that the proposed actions are appropriate and are to assess the
effectiveness of actions to achieve environmental protection. Each element of the EMP is to be assessed
relative to the Performance Criteria for the Element. Environmental audits may also identify areas that
require improvements or changes to work processes or management techniques used on the site. In cases
where changes to work process or management techniques are identified, the EMP is to be amended and
submitted to Council for approval.
The Site Manager shall perform regular inspections of the site works to identify areas that require
improvements and periodic review of environmental performance and continual improvement. Periodic
reviews of environmental performance and procedures are required to ensure the system used is still
effective, and identify opportunities for improvement. The Construction Forman will schedule periodic
meetings with operational staff to discuss and record improvement opportunities, keeping up-to-date with
industry guidelines.

Ground disturbance kept to the minimum required for construction;
Suitable ground coverage with remnant grass (undisturbed state), erosion blankets (short term disturbance) or reseeded grass
(longer term after disturbance); and
Lack of surface erosion.
Implementation Strategies The Construction Foreman shall provide temporary control measures as required during the course of the work to prevent soil
erosion, scouring, sediment transport and deposition;
n Install all temporary control measures as outlined in the Stormwater Management Plan / Sediment and Erosion Control Plan
(Appendix A) and identified in associated drawings prior to the commencement of bulk earthworks. Sequence of installation to occur
as described in Table 9 of the Stormwater Management Plan / Sediment and Erosion Control Plan. Recommended control measures
include:
Ups/ope storm water flow diversion
Construct a perimeter bank stabilised with erosion mats (e.g. jute mesh anchored by cold anionic bitumen emulsion) along the
upslope (eastern) edge of the development to divert flow around the building site, and onto grassed or stabilised surfaces on the
edge of the building site; and
Install geo-logs/straw wattles within the building site upslope of areas of high disturbance or high erosion hazard to direct flow
onto grassed or stabilised ground. Ensure secure pegging of geo-logs to prevent flow under the log. The edge of the log needs
to overlap the stable or grassed surface.
Site entry and exit points
Install an access path of crushed rock leading into the site, and directly to the stockpile area. Rock pads should be at least 15 m
long and 200 mm thick, with an underlying layer of geo-fabric. Use cattle ramps as part of the structure to allow 2 complete
rotations of the largest tyre leaving the site; and
110114_PR20517_EMP.doc Page 12
Page 17
"DJ Environmental Management Plan
Peregian Beach Caravan Park
- Install a high pressure water hose that can reach the rock pad, to remove cohesive mud.
Designated on-site stockpiles
Have a designated site for stockpiling excavated earth, building sand and building materials. Ensure that the stockpiles have
designated covers with pegs to protect them from wet weather, and are sufficiently distant from kerbside drains;
Install a geo-log upslope of stockpile area to divert flow around the stockpile;
Install a sediment fence down-slope of stockpile area to collect sediment; and
At the end of each day, or before the onset of rain, cover and securely peg stockpiles.
Downslope sediment controls
Install geo-textile sediment fences on the lower slopes of the building site. Posts should be minimum of 2m spacing; the base
should be buried at least 200 mm below ground. The fences should be concave upslope to bund stormwater, while allowing
lateral overflow down-slope;
Stabilise ground that accommodates overflow from the sediment fences to avoid rill development (refer to 'Maintaining
groundcover';
Direct overflow into down-slope sediment fence. Use filter socks as a final barrier to contain suspended sediment. Overflow from
the filter socks will be into the terminal wetland. Use water from the terminal wetland to irrigate ground cover (refer to
'Maintaining groundcover);
Install a sediment curtain in the terminal wetland to contain any fine sediment in overtopped stormwater; and
Install temporary downpipes from newly constructed roofs.
Maintaining groundcover
Maintain existing grass cover as much as possible. Reduce damage to grass cover by limiting vehicle movements to work areas
and designated access tracks;
Cover disturbed ground under erosion blanket, secured with pegs and with the edge buried below the soil surface;
Reseed disturbed soils that will be left bare, using hydromulch or equivalent. Irrigate reseeded area daily for four weeks to
establish the grass surface; and
Lay turf in areas where concentrated flow is expected (e.g. at the overflow of sediment fences).

EXECUTIVE SUMMARY Simmonds and Bristow were commissioned by Contrast Construction Pty Ltd (for the Scanlon Property Group Pty Ltd) to develop a Stormwater Management Plan (SWP) and Sediment Erosion Control Plan (SECP) for the proposed Essence of Peregian development. There are two previous versions of this plan, which represent the original plan (2009) and a modified plan for the operational works application (2010). Subsequent to these plans it has been decided that this development will be developed in stages. This revision represents Stage 1 of the development, which will include the construction of the commercial and hotel precincts (with the residential units being built at a later date). As such the SECP and SWP presented in this document are a reduced version of the existing plan to accommodate the reduced scope of the Stage 1 development. In all other respects, the SECP and SWP presented in the earlier versions (November 2009, December 2010) are the same. The SWP for the Stage 1 development describes the management of stormwater from the commercial area, the hotel, the upslope sources beyond the development area, and from stockpiled soil stored on the Stage 2 area. This SWP provides computer model outputs (MUSIC 4) that demonstrate compliance of the design stormwater quality with the required guideline standards. These standards were agreed at the Joint Experts Conference, and are consistent with loads reductions required by the Queensland Water Quality Guidelines (DERM 2009). Plans that describe the stormwater treatment train (Appendix A) and outputs from computer modelling used to support the stormwater design (Appendix B) are appended. These plans show the proposed site layout, the location of bioretention trenches, wetlands, building areas, plumbing layout, and the structure of bioretention trenches and wetlands within the development area. Procedures for maintaining stormwater treatment units (Appendix D) and implementing the Sediment and Erosion Control Plan are attached as Appendix C and Appendix E. These procedures describe how to control erosion, and minimise off-site exports of sediment and nutrients from the proposed development area during the construction and post-construction phases. A plan for monitoring water quality to demonstrate compliance with water quality objectives has also been included. 02011 Simmonds & Bestow Ply Ltd Pacific Plumbing - Scanlon Property Group Pty Ltd J-1109-155 - 8 September 2011 I ICLIEN T FILESIContrasl Constnuoonsl/ 109-155c - Essence of Pee an SCEP Stage I Updale\090utput DocumentsU I I09.155c SMP Scanlon Property G`oup_SECP_ge_ta_110905 doc

1. INTRODUCTION
Simmonds and Bristow have been commissioned by Contrast Construction Pty Ltd (for the
Scanlon Property Group Pty Ltd) to revise the Stormwater Management Plan (SWP) and
Sediment Erosion Control Plan (SECP) for re-development of the Peregian Caravan Park as
the Essence of Peregian. This revision addresses Stage 1 of the development only, and does
not reiterate discussion of receiving water quality and soils information as these were previously
described in sufficient detail (SCEP, Simmonds and Bristow, 2010)
The revised plans for the Stage 1 development describe two development phases. The
construction phase, when building activity disturbs the ground surface, is described by the
SECP. The maintenance phase, when the commercial and hotel development is fully built and
operational, is described by the SWP. The plans are intended to protect the environmental
values of receiving waters by minimising the hydraulic disturbance and loads of contaminants in
run-off from the development site.
The SECP for the Stage 1 development has adopted the existing erosion hazard and risk
assessment for the development site (SCEP, Simmonds and Bristow, 2010). The SECP
provides information on managing the erosion and off-site export of soil from the development
site, and identifies the personnel responsible for establishing and maintaining all erosion and
sediment control measures.
The SWP for the Stage 1 development describes the stormwater treatment train, which has
been reduced to managing stormwater from the commercial area, the hotel precinct, and
overland flow from upslope sources. It is proposed that stormwater from these sources will be
channelled through treatment units before release into the receiving waters of the Noosa
National Park. The SWP is based on assessments and MUSIC computer modelling of likely
changes to annual stormwater sediment and nutrient loads from the proposed Stage 1
development. The plan also provides information on managing the stormwater treatment train,
and the personnel responsible for this management.
The plans are prepared in accordance with the Queensland Best Practice Environmental
Management Guidelines 2009. References were also made to the following guidelines:
• Introductory Erosion and Sediment Control Guidelines for Queensland Councils;
• Erosion & Sediment Control: A decade of lessons learnt; and
• Controlling stormwater pollution on your building site.
This report directly follows from the revised SWP and SECP (J-1005-310: Essence of Peregian:
Stormwater Management Plan; Sediment and Erosion Control Plan, Simmonds & Bristow,
December 2010). The SWP for the Stage 1 development addresses only stormwater from the
commercial precincts, which are to be routed directly into the Constructed Wetland C2 (the
southern wetland).

3. LOCAL ENVIRONMENT
The site, surrounding land use, existing topography and stormwater flow direction were
described in the conceptual Stormwater Management Plan (Simmonds and Bristow, 2009)
The receiving environment for stormwater runoff is remnant native wet-heath vegetation that
grows along the western boundary as an extension of the Noosa National Park (Natural
Solutions, 2007). For this development it was proposed at the Joint Experts Conference that
the long term median water quality targets for stormwater entering the receiving environment
should be the values listed in Table 1. These long term targets do not apply to individual
measurements from runoff events, or to construction phase monitoring. The low pH target for
stormwater reflects the naturally low pH character of the wallum/tannin stained receiving waters.
Table 1: Water Quality Objectives
Indicator Water Quality Objectives
Suspended Solids 15 mg/ L
Total Phosphorus 35 pg/L
Total Nitrogen 350 pg/L
pH 5-7
These outcomes can also be compared with the Water Quality Objectives for loads reductions
required by the Queensland Water Quality Guidelines (DERM 2009)(Table 2). The loads
reductions water quality design objectives are important because stormwater flow is
intermittent, with most export of sediment and nutrients occurring during a few short rainfall
events each year. Management needs to cover those few rainfall events, and design objectives
for annual load reductions need to accommodate for high stormwater-flow events.

4. SITE FEATURES The planned Stage 1 development seeks to change part of the site from a caravan park to commercial, retail and restaurant uses. The remainder of the site will be developed as visitor accommodation during the Stage 2 development. The proposal for Stage 1 is a commercial development that will face David Low Way, and provide a street level frontage of retailing and restaurant services, with an accommodation module on the upper level of the building. The proposal includes car parking spaces and motor cycle bays located under the accommodation and commercial buildings. The objectives with regard to the conserving and utilising the landscape and ecological features of the site are described in the conceptual Stormwater Management Plan (Simmonds and Bristow, 2009). They include utilising existing native vegetation, topography, natural buffers to the wetlands adjacent to the national park and aspect in building design. The intensity of stormwater flows will be mitigated by one (1) large underground water storage tank for the commercial building. The captured water will be reused for non-potable domestic purposes (laundry, toilets) or for irrigation of the gardens. Stormwater will also be directed through a treatment train consisting of a Bio-retention Trench, and a Constructed Wetland System with a gabion wall diffuser adjacent to the Noosa National Park. This treatment train is designed to achieve the median water quality objectives listed in Table 1 and Table 2. 02011 Simmonds & Bristow Pty Ltd Paofic Plumbing - Scanlon Property Group Pry Ltd J-1109-155 - 8 September 2011 I CUENTFit FSCo.*a$l Cunsbuceons\11041S5c - Essence o1 Perepen SCEP Siege I Up0e4109_OubW Doo,,w sU-110-155c_SMP_Scanbn Properly Group_SECP_9ep_710905 me Page 4 of 21

J-1 105-310-07b - Rev 1 Sep 2011, Stormwater Management Control Areas Stage 1 Only;
Plans that are directly relevant to the Stage 1 development are listed in Appendix A as follows:
The Site Location (Drawing 01) and the Bio-retention Basin and Wetlands Plan (Drawing 02)
show site boundaries of the Essence of Peregian in relation to the Noosa National Park to the
west, and urban development to the north, south and east.
The Essence of Peregian development will install water sensitive urban design features to
ensure that water quality entering the Noosa National Park meets the required guideline
concentrations (Table 1). These features will capture and hold stormwater in a Rainwater Tank
and on the land, the stored rainwater will be used for domestic purposes within the commercial
complex, or for irrigating the gardens to ensure stable ground cover. Stable ground cover is an
important feature of erosion risk management.
Stormwater will be piped directly into a Bio-retention Trench (Drawing 03, Drawing 04) which is
a depression storage designed to infiltrate stormwater into the ground. This features will be
installed within fill platforms placed over the existing landscape, hence acid sulphate soils will
not be excavated and disturbed. The fill platforms in the design plans have a minimum height
of 3.3 m, which is above the 100 year ARI flood level identified for the nearby Lake Weyba (RL
2.05m AHD) (Brown, 2007). After passing through the Bio-retention trench, stormwater will flow
through a constructed wetland system (Drawing 05).
Overland flow will be diverted, via catch drains, into the Bio-retention trench (Drawing 06,
Drawing 07) for treatment by the Bio-retention trenches and constructed wetlands.
Overflow from the rainwater catch tank will be piped directly to the constructed wetland.
The development site does not fall within the flood hazard area nominated by the Noosa
Council (Brown, 2007). The stormwater treatment train is designed to accommodate the most
intense stormwater event encountered during a 5 year interval described by the ARI records
(202 mm/hour over a 5 minute period) (Australian Government, Bureau of Meteorology).
5.1. MANAGEMENT OF OVERLAND FLOW OF STORMWATER
This sub-section describes the treatment train (Drawings 02, 06 and 07) used to
manage stomiwater flowing through the Essence of Peregian development. The
treatment train is designed to keep stormwater within the landscape of the proposed
development site. There are three treatment units in the design treatment train:

Page 83
Vegetated Buffers
Vegetated buffers provide stable groundcover, thereby minimising the erosion potential
of the landscape surface. Vegetation includes grassed surfaces and deep rooted
vegetation. Energy from rainfall is dissipated over a broad, stable surface, and shallow
sheet-flow of accumulated stormwater is slowed by the rough surface provided by the
vegetation. The soil binding capacity of the plant roots, and the capacity of the plants to
assimilate nutrients from infiltration water, provides the first step of the treatment train.
Stormwater flows from the vegetated buffers into Bio-retention Trenches or directly into
the Constructed Wetland System.
Bio-retention Trenches
The Bio-retention Trenches are generally dry, but during a stormwater flow the trenches
may contain accumulated water to a depth of 200 mm, and 150 mm shortly thereafter
when the trench is dewatering. The trenches are designed to allow passive infiltration of
stormwater through the substrate of the trenches, and into the adjacent soil. The
infiltration rate is designed to allow effective assimilation of nutrients by grasses in the
trenches, which evapo-transpire some of this water, and filter off suspended solids
during the process.
Flow out of the Bio-retention Trenches is underground, with collection of filtered water in
a gravel layer that exits the trench through a Low Flow Underdrain Pipe. Flow out of the
Bio-retention Trenches during high flow will primarily be through, and across, the crest of
the gabion weirs. Maximum flow depths over the weir crests in the 100 year local runoff
event are estimated to be less than 25 mm, assuming minimal flow losses through the
gabion weir walls due to long term blockage. Outflow is towards the Constructed
Wetland System.
Constructed Wetland System.
The Constructed Wetland System features permanent water bodies that provide a final
polishing step to stormwater flowing through the treatment train. Suspended solids
settle out within the standing water, and the flora and fauna within the constructed
wetlands assimilate nutrients. Pollutants that may enter the Constructed Wetland
System are contained, diluted by the large volume of water in the standing water body,
and collect in sediment at the base of the wetland system or at the water margin. The
processed stormwater in the water column can exit the Constructed Wetland System
through the gabion diffuser wall.
The Constructed Wetland System provides an ecological barrier to pest flora entering
the Noosa National Park. By maintaining local plants within the Constructed Wetland
System, and removing weeds, the Constructed Wetland System is designed to work as
an ecological barrier.
5.2. PROPOSED TREATMENT TRAIN
This sub-section describes the proposed treatment train for stormwater management
associated with the operating phase of the developed site (after construction is fully
complete). The treatment units include a Rainwater Tank, Vegetation Buffers,
Bioretention Trenches and the Constructed Wetland System used to manage
stormwater. The treatment train sequence is shown in Appendix B as follows:

Commercial Section
1) Direction of flow from the Commercial area (hotel, restaurant roof, tank) into Wetland
C2
2) Direction of flow from the South balance (overland flow) and Commercial area
(restaurant podium) into Bio-retention Cl,
3) Direction of flow from Bio-retention C1 into Wetland C2.
Stormwater that has passed through all these treatment units enters the receiving node
(Appendix B). The design stormwater quality passing through the treatment units, as
well as into the receiving node, were modelled using MUSIC Version 4.
5.3. MODELLING OF THE STORMWATER TREATMENT TRAIN
Results of MUSIC modelling showed that there will be a decrease in stormwater runoff
from the Stage 1 development area. Loads of sediment, total nitrogen and total
phosphorus will be substantially removed from stormwater before entering the Noosa
National Park from the Stage 1 development area (Appendix B).
There will be an 84% reduction in stormwater entering Noosa National Park, from 6
MUyear to 0.9 MUyear. The annual load of total suspended solids from the
undeveloped commercial area is about 1000 kg/year, whereas the annual load from the
developed site is 140 kg/year (Appendix B). Likewise, annual loads for total nitrogen
and total phosphorus are also expected to be an order of magnitude lower than the
present load from the existing caravan park site (Appendix B).
Water Quality predictions from the MUSIC model (Appendix B) indicate that
contributions of total suspended solids, nitrogen and phosphorus in treated stormwater
from the developed site (Table 3) comply with the required water quality objectives
(Table 1 and Table 2). The median design concentrations are expected to be below the
required water quality objectives, and 90% of the time this should be the case (refer to
receiving node results listed in Appendix B).
The predicted maximum concentrations of suspended solids, nitrogen and phosphorus
in extreme stormwater flows might temporarily exceed the guidelines (Appendix B), but
the design concentrations (Table 3) will be improved from the existing water quality in
the terminal wetland measured after a stormwater flow event (refer to Table 3 in
Simmonds and Bristow, 201OErrorl Reference source not found.). The MUSIC
modelling indicated that the treatment train for the Essence of Peregian development will
improve the water quality of stormwater entering the terminal wetland.

The Noosa River: Environmental Values and Water Quality Objectives state that the
environmental values associated with the Noosa River Wetlands include aquatic ecosystem
protection, and cultural and spiritual values. Because Noosa National Park is a protected area,
these values require a high level of protection (level 1 protection).
During the construction of the Essence of Peregian Stage 1 development, there is a hazard that
disturbed soil might be carried into the wetland by stormwater. Mobilisation of stockpiled
sediment is of particular concern, but this hazard can be easily managed. In particular, fine
sediment mobilised by stormwater will potentially carry nutrients into the wetland. The likely
consequence of this is increased nutrient availability to weeds, with potential negative
consequences for the adjacent Noosa National Park ecosystem.
Assessment of the Queensland Best Practice Environmental Management Guidelines (DERM,
2009) checklist (Table 5), shows that overall there is a high erosion hazard for this site. This
hazard is directly affected by soil type (particularly imported fill on lower slopes), the need to
reshape the ground surface to construct structures, and the anticipated duration of site
disturbance being 3 to 6 months. The hazard is greater during the wet season between
November and July when the average monthly rainfall is expected to be above 100 mm.

Extent of site disturbance 2 11 or up to 15
Total Score 11 -15 High Erosion Risk
By implementing sediment and erosion controls, it is possible to moderate the erosion hazard.
This includes protective covering of disturbed soils (particularly on erosion prone parts of the
landscape, and when rain is expected), promptly revegetating soil that is planned to be
stockpiled in the Stage 2 area (in anticipation of future development), scheduling work to avoid
the highest rainfall risk period, installing upslope diversion of runoff away from soil disturbance,
and installing purpose built sediment control traps down-slope of the soil disturbance.
The SECP has identified construction site best practices for managing sediment erosion and
control. A daily site check-list will be used to ensure that building contractors are cognizant of
and performing the required management actions. This check-list is attached in Appendix C.
The SECP also coordinates stormwater management with construction milestones, for effective
implementation of sediment erosion and control measures during the construction phase.
The plan layout of the SECP in the proposed development area is shown in Drawing J-1005-
310-08 (Appendix E), which shows where erosion management structures need to be placed
during construction activities. Slope-related erosion hazard areas within the development site
were identified from the topographic map (Drawing J-1005-310-09 in Appendix E), and
represent control points within the construction site where particular care will be needed. The
management actions for controlling erosion of the site, and movement of sediment and nutrients
from the site, are described in Table 6. The detail management plans for sediment and erosion
control are described in Appendix E.

8. ENVIRONMENTAL IMPACT ASSESSMENT
The environmental impact of stormwater from the development was assessed using the
accepted solutions for managing stormwater quality in South East Queensland. The Water
Sensitive Urban Design Deemed to Comply Solutions for South East Queensland (henceforth
termed "the Solutions") outlines a seven step process for selecting and designing stormwater
management solutions, to achieve the stormwater management outcomes required by DERM
(2009). The Solutions identify acceptable solutions for "common" development scenarios to
meet design objectives, which are:
1) Stormwater Quality: Limiting the quantity of pollutants by adopting a best practices pollutant
load reduction approach, with consideration of the local climate.
2) Waterway Stability: Controlling the magnitude and duration of stormwater flows, to prevent
exacerbated in-stream erosion downstream of the development.
3) Frequent Flow: The hydraulic disturbance of in-stream ecosystems is similar to the pre-
development condition, which is achieved by capturing the initial portion of runoff from
impervious areas.
The proposed Essence of Peregian development will be in the Sunshine Coast Regional
Council jurisdiction, which is in the North Coast climate region of South East Queensland. The
proposed development type is residential land use, with a scenario of residential development
greater than 2 lots up to 20 lots. The residential development scenario can include commercial
development of high-density, multiple dwelling buildings at a scale of <_ 12,500 m2. This
scenario applies to the 6,970 m2 commercial node of the "Essence of Peregian" Stage 1
development.
The site details of the Essence of Peregian Development are presented on the annotated site
details plan (Appendix C), and summarized in Table 8.
Table 8: Site Details of the Essence of Peregian Development
Site Detail Description
Existing topography The average grade is 12% across the Stage 1 development area and 3 6%
across the entire development (Stage 1, Stage 2 & Stage 3), with a preferred
flow pathway from east to west across the development.
Existing Drainage Characteristics There are no significant existing drainages in the proposed development area.
Proposed Discharge Points and A proposed stormwater drainage has been designed for this development
Invert Levels (refer to plan drawings in Appendix A).
Soils The surface and sub-surface soils of the proposed development area include
imported fill. silty-clay, silty-sand, and fine sand. The surface soils are acidic,
with low nitrogen concentration and very low salinity. Acid sulphate soils may
occur in the sub-surface, but these soils will not be excavated or disturbed
because additional fill will be placed over them.

Development details (site layout, sub-catchments, conceptual earthworks and conceptual
drainage) are provided as plan drawings in Appendix A (drawing numbers J-1005-310-01 to
05). Specifications of the site layout (roof area, balance area) are given in Appendix B. The
south sub-catchment (drawing J-1005-310-07 & J-1005-310-07b) will feature a designed
treatment train that flows from the Stage 1 development toward the Constructed Wetland
System and the receiving node of the receiving waters next to the Noosa National Park.
The Solutions state minimum sizes of Rainwater Tanks, Bio-retention systems and Constructed
Wetlands that are required to meet the Queensland Development Code Mandatory Part 4.2 and
4.3, and the stormwater quality objectives outlined in the Best Practice Environmental
Guidelines - Urban Stormwater. The stated dimensions proposed for the Essence of Peregian
development are listed in Table 9.

The Rainwater Tank is sized appropriately for the commercial building, with ample volume to
satisfy the non-potable water use requirement of the Qid Development Code MP 4.3. The
surface areas represented by the Bio-retention Trenches (0.6 % of the catchment area) and the
Constructed Wetland System (3.2 % of the catchment area) are less than the WSUD Deemed
to Comply Solutions (1.1 % and 6 % respectively).
It is possible to design a stormwater treatment train outside the prescribed parameters,
provided that the Best Practice Environmental Management Guidelines - Urban Stormwater and
the planning requirements of the assessment authority are followed. A carefully designed
stormwater treatment train has been proposed by the Stormwater Management Plan, and has
been supported by detailed MUSIC modelling (Section 5).
In summary, the Environmental Impact Assessment indicated that the proposed Essence of
Peregian Stage 1 development will have negligible consequences resulting from total
suspended solids, total nitrogen and total phosphorus entering Noosa National Park. The
treatment train for the SWP has been designed to minimise the effects of rainfall and
stormwater erosion of the landscape, retain rainwater collected on roofs and hard surfaces for
irrigation and commercial use, and direct remaining overflow through Bio-retention Trenches
and the Constructed Wetland System. Detailed MUSIC modelling identified that the proposed
development will achieve the required water quality objectives (Appendix B). Suspended solids
and total nutrients will be removed early in the treatment sequence (Appendix B). It is predicted
that the maximum concentrations of pollutants in stormwater during extreme events (Appendix
B) will be substantially less than concentrations presently measured in stormwater entering the
terminal wetland from the existing caravan park site (Table 3Errorl Reference source not
found.)

9. MONITORING AND EVALUATION OF WATER QUALITY AGAINST TARGETS
A draft water quality monitoring program has been developed to measure the performance of
the proposed stormwater treatment train against targets (Table 1). The objective of the
monitoring program is to quantitatively show whether or not the nominated water quality targets
are being met.
The key water quality indicators are total suspended solids, total nitrogen, total phosphorus and
pH (Table 1). Other relevant water quality parameters include microbiological parameters
(faecal coliforms, Escherichia colt), chemical and physical parameters (dissolved oxygen,
turbidity), and herbicides if they are used within the development site. The following water
quality indicators are recommended (Table 10):
• Microbiological: Faecal coliforms, Escherichia coli
• Physical: Biological Oxygen demand, dissolved oxygen, suspended solids, turbidity,
pH;
• Chemical: Total suspended solids, total nitrogen, total phosphorus; and
• Herbicides: If herbicides are used to control weeds on the development site, then
they should be included in the suite of water quality indicators.

It is recommended that the water quality of the terminal wetland is represented by four (4)
sampling points per sampling event (i.e. 4 spatial replicates): two (2) from the Constructed
Wetland System and two (2) more from the heath on the west of the terminal wetland (adjacent
to Noosa National Park). The recommended sample points are indicated in Table 11, which
lists the location of sample points during the construction phase and the operational phase.
Monitoring needs to commence during the construction phase, and continue during the
operational phase.

Water Quality Monitoring During Construction
During construction, monthly monitoring for the parameters described in Table 10 is
recommended from sites 3 and 4 (Table 11). Additionally, it is recommended that the
suspended solids concentration of stormwater is measured at sites 5 to 9 during stormwater
events, with collection of four (4) stormwater samples flowing onto the construction site, four (4)
more stormwater samples flowing from the construction site into the terminal wetland, and a
rain-gauge is installed on site to indicate the intensity of rainfall during a stormwater event
(Table 11).
Inflow and outflow water needs to be collected as paired samples within a short time frame, with
each pair representing the same phase of stormwater activity. The volume of stormwater
generated in the catchment can be calculated by the area of catchment and the intensity of
rainfall during the event. The proportionate change in the suspended solids loads in stormwater
flowing over the construction site will provide a measure of the sediment being generated from
the construction site.
Herbicide monitoring in stormwater entering and leaving the construction site should be
performed when applications are known to occur, rather than routinely. Some herbicides have
a short residence time, so arrangements may need to be made with the laboratory for rapid
courier service and turnaround time. The monitoring schedule is listed in Table 12
The temporal frequency of stormwater monitoring during the construction phase is listed in
Table 12.
Water Quality Monitoring During Routine Operation of the Essence of Peregian
Sampling should be performed at sites 1 to 4. The temporal sampling frequency is
recommended at monthly intervals for the first 12 months, with quarterly sampling thereafter
(Table 12). This temporal frequency is intended to show the proportional improvement from the
existing water quality condition in response to improved stormwater management associated
with the new development. Seasonal variations can be identified from the quarterly samples.
Herbicide monitoring is as described for the construction phase.

10. CONDITIONS AND LIMITATIONS The data contained in this volume has been commissioned by Contrast Construction Pty Ltd to support a Development Application for Operational Works associated with the development known as 'Essence of Peregian' located at 215-219 David Low Way, Peregian Beach. In preparing this report, Simmonds and Bristow has, in part, relied on survey data, flood level data, calculations and previous reports prepared by Council and external consultants to support the original development application, and the preparation of Joint Experts Reports for the court ordered mediation process associated with the preparation of the negotiated approval conditions. While reasonable precautions have been taken to validate the data provided before its incorporation into modelling and design procedures, the absolute accuracy of such data cannot be guaranteed with certainty and may vary over time as site conditions change. As such, it is anticipated that minor changes may be required on site to allow the recommendations of this plan to be implemented effectively. Minor or temporary changes to accommodate on-site conditions during the construction phase should be made in consultation with a suitably qualified and experienced professional engineer or qualified sediment and erosion control specialist. Any proposed permanent changes required to the layout, geometry, depth and/or volume of bio- filtration basins and/or wetland elements as a result of any site conditions that are different to those assumed and modelled during design, should be referred back to the designer, or to a suitably experienced and qualified stormwater management consultant, and resubmitted to Council for compliance re-cert ifi cation and approval. The Stormwater Management Report contained within this report comprises of all constituent parts of the report in full, including the text, calculation summary and appended drawings. If additional copies of this report are required, separate sections or individual pages must not be copied in isolation. Except for archival and record keeping purposes, this report should not be copied and stored in any electronic media or passed onto other parties without the express written permission of Simmonds & Bristow. No part of this report may be copied or used for any other purposes other than the purpose stated in this report. 02011 Simmonds & Bestow Ply Ltd Pacific Plumbing - Scanlon Property Group Ply Ltd J-1109-155 - 8 September 2011 I %CLIENTFILES1Conuast Construcoons11109-155c - Essence of Pemggan SCEP Stage I Updateb9 Output Ooc,nnenlsU-1109-155c_SMP_Sunbn Properly Gmup_SECP_ge_tn_ 110905.doc Page 17 of 21
