1. EXECUTIVE SUMMARY This Sustainability Management Plan (SMP) provides an overview of the sustainability initiatives that

have been assessed for inclusion in the proposed developments located at 40 Hall St and 34-36

Margaret St, Moonee Ponds. The stage 1 development comprises of a 13 and 23 storey apartment

building – summarised below.

Building Elements Project Details

Municipality Moonee Valley City

Classifications Class 2

Total apartments 626

Total car parks 551 + 21 motorbike parks

Bicycle parks 226

Commercial tenancies 6

Site Area 7796.60 m²

This SMP will provide a detailed sustainability assessment of a proposed design at the planning stage.

An SMP identifies beneficial, easy to implement and best practise sustainability initiatives in line with

Moonee Valley City council Sustainability framework. This includes:-

A practical approach to assessing sustainable development matters during the planning permit

application process.

The consistent inclusion of key environmental performance considerations into the planning

approvals process.

A guide to achieving more sustainable building outcomes for the long–term benefit of the wider

community.

The initiatives proposed provide a holistic approach to sustainability within the multi-residential built

environment; however a focus on indoor environment quality, energy efficiency (electrical and gas),

water efficiency and stormwater management has been applied. This report references various

sustainability frameworks, checklists and benchmarks, all of which were used to qualify and develop the

initiatives. As a result, the initiatives proposed for 40 Hall St and 34-36 Margaret St, Moonee Ponds have

been specifically tailored to the development, yet appropriately benchmarked against similar

developments to help assess the levels of sustainability proposed.

The development has achieved room layouts that promote natural ventilation and maximised natural

daylight to living areas. The layout also removes the need for air conditioning during a vast majority of

the year by controlling thermal loads in both summer and winter design conditions. This arrangement is

predominantly achieved with high performance glazing, external solar shading devices, suitable ratios of

glazing fenestration to facade area and sufficiently sized window/door openings to promote natural

ventilation.

The development provides an instantaneous domestic hot water system. Natural gas is a fuel which has

significantly lower associated greenhouse gas emissions than grid connected electricity (which generally

uses brown coal as its primary energy source).



LCE8132-015 5

This development incorporates rainwater storage for re-use within the development for toilet flushing

and also irrigation of the various landscaped areas proposed. As such, the development is shown to

have significantly reduced the reliance on mains water as compared with typical residential dwellings of

similar use.

The development will achieve a minimum average 6.0 stars, as per the requirements outlined by the

Building Code of Australia.

2. PROJECT INFORMATION

2.1 Description of Development

The stage 1 development at 40 Hall St and 34-36 Margaret Street, Moonee Ponds consists of a 13 and

23 storey residential apartment building, totalling 626 apartments, parking located in three basement

levels, storage space and bicycle racks.

Fig. 2.1 Satellite image of proposed stage 1 development location. Proposed location is shaded in blue.

The development scores well on ‘Walk Score’, achieving a rating of 98 – Walker’s Paradise. This indicates

that daily errands can be accomplished without the need of a car. This fact, coupled with the close

proximity to public transport, ensures the development is inherently sustainable, as occupants will be

significantly less reliant on cars for their primary form of transport.

2.2 Sustainability Framework

Sustainability is a term that is typically used to describe the intent to balance the elements of society,

economics and the environment. This report focuses primarily on the ecologically sustainable

development (ESD) initiatives for the proposed development and it is considered that social and

economic aspects are also addressed either directly or in-directly where relevant.

The development adopts good passive design principles and building services to achieve sustainable

outcomes using simplistic, practical, low maintenance and cost effective design concepts.

LCE8132-015 10

3.1 Indoor Environment Quality

Indoor environment quality is critical for the health and well-being of all building occupants and users.

Residential developments which have a high level of indoor environment quality typically have greater

levels of occupancy and extended occupancy periods. Indoor environment quality can be measured

utilising metrics such as air quality, lighting and noise/acoustics, as well as external views. Buildings with

higher levels of indoor environment quality have been found to promote general physical and mental

health, as well as improve productivity within workplaces.

Issues

The issues relevant to indoor environment quality 40 Hall St and 34-36 Margaret St include:

Thermal Comfort

Natural Ventilation

Daylight

External Views

Glare Prevention

Hazardous Materials and VOC

Electric Lighting Levels

Acoustics

Artificial Light Quality

Ventilation of Common Areas

The proposed initiatives aim to deal with the above issues.

Proposed Initiatives

1. For the provision of sufficient daylight, habitable rooms of single aspect are within close proximity to a

bedroom window.

All habitable spaces within the proposed development receive direct sunlight from windows in each

habitable room, ensuring that all areas receive adequate natural lighting.

2. Living rooms and private open spaces will receive a minimum of 3 hours direct sunlight between 9am

and 3pm in mid-winter.

The majority of all apartments have access to either the Eastern, Northern or Western façades, and as

such receive direct sunlight in all living areas for a minimum of 3 hours of direct sunlight per day in mid-

winter.

3. 100% of apartments have access to natural or forced cross ventilation (either directly or in-directly).

To ensure apartments which do not have access to façade cross ventilation are still provided with a high

level of indoor environment quality, it is proposed to ventilate (with 100% outside air) the

circulation/lobby areas on each floor. This will effectively result in air passing through the apartments,

via gaps in doorways, before exiting through operable window areas to balcony areas. This level of

ventilation is considered an appropriate alternative to cross ventilation, and is provided to all

apartments within the development.



LCE8132-015 11

Figure 3.1 – Forced cross ventilation to apartments

4. Windows/openings to apartments are appropriately positioned with acoustics in mind. Windows are

sealed appropriately to avoid noise transmission.

All apartment living/sleeping areas are positioned with acoustics in mind, and all windows/glazed areas

are appropriately sealed. The development is not considered to be in an area with significant acoustic

issues, with only lower level apartments likely to receive background street noise.

5. Lighting in apartments will be provided with high colour rendition index and warm white colour to

increase occupant comfort levels within apartments.

The light fittings to be installed within the apartments are to increase occupant comfort by providing

colour schemes which suit the nature of the development.

6. Apartment bathroom and kitchen exhaust to balconies for discharge to ambient in-lieu of recirculating

range hood type kitchen hood.

Apartment exhaust is to be ducted directly to balcony areas, to ensure all contaminants/odours are

removed directly from the apartment interior. The exhaust discharge will be located 1 meter away from



LCE8132-015 12

any air intake zones. According to the Australian Standards specifically AS1668.2-2012, this distance is

adequate for an airflow rate of 200L/s, which is sufficient in this scenario.

Benchmarks and Supporting Evidence

The initiatives proposed relating to indoor environment quality were formed utilising the legislative

requirements of the National Construction Code 2014. CIBSE Environmental Design Guide was used as

guidance documents.



LCE8132-015 13

3.2 Energy Efficiency

Energy efficiency is considered critical for ensuring that usage of non-renewable forms of energy is

minimised, such that continued population growth and consumption does not continually damage the

environment. Additionally, energy efficiency has a direct financial benefit, as it reduces exposure to the

rapidly increasing cost of utility supplied electricity and gas, as well as associated CO2 emissions.

Residents of energy efficient developments can enjoy reduced expenditure on power bills (in both

tenant owned areas and common areas), whilst also reducing their impact on the environment.

The development focuses on passive design features to improve energy efficiency; such features do not

consume operational energy and generally last the lifetime of the building > 50 years. Furthermore,

mechanical air conditioning systems comprising electric driven, refrigeration cycle equipment are

responsible for as much as 50% of residential greenhouse gas emissions and contribute significantly to

the issues of peak electrical demand which has a negative impact on the cost of electrical infrastructure,

cost of electricity network charges and the (in) efficiency of electrical energy generation and

transmission during these periods.

These operational effects of buildings further demonstrate the importance of passive design and access

to natural daylight and effective natural ventilation. The following pie chart demonstrates a breakdown

of energy consumption within a typical home.

Figure 3.2 – Where energy is used in the home.

Issues

The issues relevant to energy efficiency for 40 Hall St and 34-36 Margaret St include:

Operating Energy

Energy Sub-Metering

Lighting Power Density

Lighting Zoning

Peak Energy Demand Reduction

Air leakage minimised

Efficient Shading

Building Fabric enhanced over minimum BCA requirements



LCE8132-015 14

HVAC zoning

Efficient HVAC system

Efficient onsite generation of electricity

Allowance for efficient fans and pumps (e.g. VSD)

Encouraging occupants to utilise energy more efficiently



1. Preliminary modelling has indicated apartments achieve NatHERS rating greater than 6.0 Stars

(average).

Preliminary NatHERS modelling, using FirstRate V5, has been completed for the proposed development,

with results indicating that a NatHERS rating greater than 5.0 stars with an average of 6.0 star result is

achievable. This satisfies the legislative requirements for Victoria, indicating that a high performing

passive design is achievable. Refer to Section 5.2 for a summary of the preliminary modelling.

2. High efficiency lighting is provided to apartments and common areas, including automated lighting

control to common areas only.

The development is to incorporate high efficiency light fittings coupled with time switches, motion

sensors and daylight sensors where applicable, to ensure that lighting energy consumed is minimised.

3. All heating and cooling systems are to have an energy star rating of at least 3 stars.

A preference will be given to air conditioning (reverse cycle heat pump type units) with higher star

ratings throughout the design where possible. It is however expected that the passive design of the

development will lead to air conditioning run times being significantly reduced.

4. All hot water systems are to have an energy star rating of at least 5 stars

Hot water systems are to be of the instantaneous gas fired ‘condensing’ type, leading to a highly

effective and efficient domestic heating water system.

5. High efficiency lighting throughout; generally comprising of new generation T5 carparks, plantrooms

and stairwells, and LED lighting to remaining areas. All general lighting will have an efficient no less than

80 lumens / watt.

Common areas which require long hours of switched lighting are to have energy efficient fittings to

reduce lighting consumption.

6. Common areas are to incorporate daylight harvesting.

Areas where natural light can temporarily reduce/remove the need for artificial lighting are to

incorporate daylight sensing.

7. Gas metering at hot water plant to track gas consumption.

It is proposed to separately meter the hot water plant to allow for landlord gas consumption. This

allows for a better picture to be gained as to how well the plant is operating, as well as assists in

monitoring the consumption of the unit.

8. Variable speed drives and CO monitoring for car park exhaust fans to reduce fan energy consumption.



LCE8132-015 15

It is proposed to utilise carbon monoxide sensing and variable speed drives to ensure that car park

exhaust fans only operate on an as needs basis, drastically reducing fan consumption

9. Provide multi-stage pumps for potable water supply.

Potable water pumps are to be multi-stage, to reduce overall pumping energy.


The initiatives proposed relating to energy efficiency were formed utilising the legislative requirements

of the National Construction Code 2014 and the NatHERS requirements. Additionally Sustainable

Design in the Planning Process Fact Sheet and was used as guidance documents.



LCE8132-015 16

3.3 Water Efficiency

Water efficiency is deemed critical due to the growing needs of Melbourne’s population, and the

current wasteful actions of general households when it comes to potable water usage. Additionally,

water is a costly resource which is in turn becoming a financial burden.

The development St utilises high efficiency fixtures and fittings to minimise the consumption of the

water used. Additionally, the development proposes extensive metering is utilised to effectively track

consumption and manage the usage per resident.

Issues

The issues relevant to water efficiency for 40 Hall St and 34-36 Margaret St include:

Minimising Amenity Water Demand

Water Metering

Heat Rejection Water

Fire Systems Check Water Consumption



1. All fittings and fixtures are to be installed with a WELS rating of within one star of the highest

available at time of Council endorsement.

Selection of fittings, fixtures and water consuming equipment is paramount for achieving a water

efficient building. All fixtures and fittings shall be selected as low flow with appropriate Water Efficiency

Labelling (WELS) where relevant.

Shower heads with a WELS rating of not less than 3 stars (9 L/min)

Water closets with a WELS rating of not less than 5 stars (3.5 L/flush, dual flush)

Basins with a WELS rating of not less than 5 stars

The following table demonstrates the potential water savings achievable through the use of low flow

equipment:-

Total 256 L 175 L

Table 3.3– Comparison of average residential water consumption (per person)

2. All dwellings are to have separate water meters.

To better monitor water consumption, and to ensure tenants responsibly use mains water, all dwellings

are proposed to be metered.



LCE8132-015 17

3. Water from sprinkler testing is to be re-captured, and monthly tests are to be adopted in lieu of weekly.

All test water used in fire pump testing will be re-circulated and recycled in the fire storage tank. Lower

level retail sprinkler control valve test water will be collected in the detention tank for re-use. Remote

testing has a tendency to have discoloured water and will be discharged to stormwater as it is not

deemed suitable for re-use.

AS1851-2005 is to be adopted which allows for the testing of sprinkler systems to be a monthly

occurrence, in-lieu of weekly – ensuring the development reduces potable water consumption whilst

still adequately meeting Australian Standards for testing of fire safety systems.

4. Rainwater collection and re-use

It is proposed to provide a total of 70kL of rainwater storage capacity across the Stage 1 development,

allowing capture of rainwater from all rooved areas and outdoor areas. The water will then be

reticulated for re-use to serve toilet flushing to the equivalent of 325 bedrooms, and will serve

landscaped areas.


The initiatives proposed relating to water efficiency were formed utilising the legislative requirements of

the National Construction Code 2014. Additionally WELs Rating system and was used as guidance

documents



LCE8132-015 18

3.4 Stormwater Management

Issues

Due to the urban nature of Melbourne, a large proportion of the land which was once exposed soil has

now been replaced with impervious surfaces such as roads, sidewalks and roofs. Stormwater discharge

direct to Port Phillip Bay without natural filtration through plants and soil presents numerous pollution

issues, as well as causes unsafe stormwater flooding due to the large quantities of water flowing.

The proposed development is to replace an existing building and car park, which currently is providing

a minimal level of stormwater management. As such, the net result of the development from a

stormwater management perspective is a significant improvement.

The issues relevant to stormwater management for 40 Hall St and 34-36 Margaret St include:

MUSIC modelling

Watercourse Pollution

Stormwater caption


Initiatives

1. Victoria’s best practice stormwater management objectives are assessed.

As an alternative to STORM, a Model for Urban Stormwater Improvement Conceptualisation (MUSIC)

simulation was conducted, in accordance with the Melbourne Water MUSIC Guidelines. Refer to

Appendix C for the MUSIC assessment conducted for Hall St and Appendix D for the MUSIC assessment

conducted for Margaret St which include full details of the initiatives, system connections and water

catchment areas. The following Water Sensitive Urban Design elements are recommended, in order to

reduce potable water consumption and to treat and retard stormwater run-off.

Hall St proposed initiatives

8 x 5kL Rainwater Tanks to capture 100% of roof water and runoff from level 4 outdoor areas.

Rainwater tanks are to be used to be plumbed for to 174 toilets, up to level 6.

2 x 6m2 rain gardens to be located on the ground level, which are to treat runoff from the tennis

court and outdoor areas located to the east and north of the development.

Landscaped outdoor areas on the ground and level 4 to reduce overall impervious area.

Water saving fittings and appliance (WELS) are to be used.

Margaret St proposed initiatives

6x5kL rainwater tanks to capture 100% of roof water and run off from level 6 outdoor areas. The

tanks are to be located on Basement level 1.

Rainwater tanks to be plumbed for re-use to 151 toilets up to level 6.

Landscaped outdoor areas on the Ground Floor and Level 4 to minimise overall impervious area.

Water saving fittings and appliance (WELS) are to be used.


The initiatives proposed relating to stormwater management were formed utilising the legislative

requirements of the National Construction Code 2014, as well as MUSIC modelling.



LCE8132-015 19

3.5 Building Materials

The building sector is a large consumer of raw materials, and the processes used, particularly in

Australia, in constructing and transporting the materials to site is carbon emissions and energy usage

intensive. As such, the need for concise selection of building materials which are fit for purpose, and not

beyond what is considered to be required is critical.

As the scale of the development is large, and the level of building materials used is significant, the

initiatives presented in the section are essential to the outcome.

Issues

The issues relevant to building materials for 40 Hall St and 34-36 Margaret St include:

Storage for Recycling Waste

Reuse of Materials and other Recycled Materials

Embodied Energy of Concrete

Embodied Energy of Steel

Sustainable Timber

Design for Disassembly

Environmental toxicity



1. Limited usage of high embodied energy metals and materials (such as zinc, etc.).

The project will aim to minimise usage of high embodied energy metals and materials where applicable.

2. The project may substitute portland cement with industrial waste/oversized aggregate where

appropriate.

Areas of the project may incorporate industrial waste/oversized aggregate to replace the usage of

Portland cement where applicable.

3. Timber used in the project is to be re-used timber, post-consumer recycled timber or Forestry

Stewardship Council Certified where feasible.

Timber used within the project is to be FSC certified where feasible.

4. Materials used within the project are selected to be recyclable/reusable where applicable.

Construction materials are to be selected with an intention to re-use or re-cycle materials.

5. The project is to avoid the use of materials which are toxic in manufacture or use.

The project will aim to completely avoid the usage of materials which are considered toxic, and are

manufactured from such processes where toxic chemicals are used.

6. In general, products which are locally manufactured are to be sourced and implemented where feasible.

Products which are sourced from overseas are to be shipped in lieu of transportation by air where feasible.

Building materials are to be selected with transportation environmental and carbon footprint in mind, as

well as efficiency of the form of transportation. A preference will be given to locally sourced materials.



LCE8132-015 20

7. All materials selected are deemed suitable for their intended application.

The building is to be appropriately designed to ensure all materials are correctly selected and used in

the construction.

8. Materials have been selected with consideration of maintenance/durability. Materials which require

toxic/polluting/high energy using cleaning methods are minimised.

Materials are to be selected with maintenance and durability in consideration.

9. Increase percentages for recycled material usage, or commit to avoid the use of certain materials. A

construction waste minimisation plan is to be completed.


The initiatives proposed relating to building materials were formed utilising the legislative requirements

of the National Construction Code 2014.



LCE8132-015 21

3.6 Transport

Car usage within Australia is responsible for approximately 50% of total transport greenhouse gas

emissions. Additionally, the level of car usage within Melbourne greatly dominates over other forms of

transport as the most commonly used. Car usage additionally contributes to a number of noxious

airborne pollutants, which can significantly affect air quality within cities where congestion is an issue.

Consumption of limited oil resources also make car usage an unsustainable and costly form of

transport, as such, the need for suitable alternatives to be provided is critical.

The construction/residential industry can respond well to the above issues by ensuring that

developments are adequately serviced by existing or proposed public transport, and that suitable

alternative forms (such as cycling) is well accommodated for. 40 Hall St and 34-36 Margaret St provide

cycling facilities and is within a short distance of existing public transport infrastructure.

Issues

The issues relevant to transport for 40 Hall St and 34-36 Margaret St include:

Providing secure bike storage facilities

Green Travel Plan

Figure 3.6 – Walk Score for 40 Hall St and 34-36 Margaret St, Moonee Ponds



1. Secure cyclist storage is provided with 226 bike parks

Encouraging residents to utilise cycling as an alternative form of transportation.



LCE8132-015 22

Figure 3.6a: Example of proposed Basement bicycle rack location

2. Detailed information on nearest public transport options, as well as details of public amenities within

walking/cycling distance is to be provided to occupants, to reduce reliance on cars.

It is proposed to provide to occupants details of all nearby public transport, as well as nearby public

amenities within walking/cycling distance, to ensure occupants are completely aware of the facilities

which are within reach without the need for car usage. The below demonstrate that building occupants

can reach Flinders Street Station within 25-30 minutes by car and within 30 minutes by bike.



LCE8132-015 23

Figure 3.6b: The time and path to Flinders Street via car and bike, respectively.



LCE8132-015 24

3.7 Waste Management

Construction waste management is considered critical as up to 40% of landfill in Australia can be

attributed to the construction and demolition of buildings. On top of this is the on-going building

occupant waste as a result of everyday living and consumption. Managing and planning for such waste

is necessary to act on reducing the quantity of going to landfill, whilst also ensuring that materials

which can be appropriately recycled are treated separately.

The development proposes to manage waste during construction and throughout the lifespan of the

building through the setting of recycling targets, providing facilities for occupant waste separation.

Issues

The issues relevant to waste management for 40 Hall St and 34-36 Margaret St include:

Construction Waste Management Plan

Construction Environmental Management Plan

Operation Waste Management Plan

Operation Environmental Management Plan

Storage spaces for recycling and green waste

Contractor has valid ISO14001 accreditation



1. A recycling target of 70% of all demolition and construction waste is to be adopted.

A recycling target of 70% of all demolition and construction waste (by mass) is proposed to ensure that

all materials collected which are appropriate for reuse are suitably recycled, in-lieu of being disposed of

in landfills.

2. Adequate facilities for occupant waste separation are provided.

The development is proposed to include a separate general waste and recycle disposal points on the

basement level (connected to a separate garbage chutes), to allow for occupants to dispose of their

waste correctly.

3. Recycling targets are to be reviewed throughout the construction period and a waste minimisation plan

is to be completed, to ensure all recyclable material is correctly recycled/re-used.

It is proposed to periodically review recycling targets throughout the construction phase, such that any

additional recyclable materials can be disposed of appropriately.



LCE8132-015 25

3.8 Construction and Building Management

The process of delivering, commissioning and managing a sustainable building can often be

challenging. In many cases, the sustainable initiatives are heavily reliant on commissioning and

installation aspects which can be easily overlooked. Additionally, without appropriate maintenance,

systems may end up operating inefficiently or in a wasteful manner.

The development aims to set and review recycling targets and prepare a stormwater pollution reduction

strategy during construction, as well as the planning for on-going maintenance.

Issues

The issues relevant to construction and building management for [Click here to enter project code]

include:

Construction Environmental Management Plan

Contractor has valid ISO14001 accreditation

Operation Environmental Management Plan

Building Tuning

Building User’s Guide



1. A recycling target of at least 70% for all demolition and construction waste (by mass) will be adopted.

A recycling target of 70% of all demolition and construction waste (by mass) is proposed to ensure that

all materials collected which are appropriate for reuse are suitably recycled, in-lieu of being disposed of

in landfills.

2. The site will commit to regular fine tuning of building services and on-going maintenance.

Maintenance contracts will be created to ensure that all systems within the building are operating as

intended, and that no systems are operating wastefully/inefficiently.



LCE8132-015 26

4. SUMMARY OF SUSTAINABILITY INITIATIVES

Indoor Environment

Quality

Sufficient daylight will be provided to the majority of habitable rooms

of single aspect apartments.

Living rooms and private open spaces will receive a minimum of 3

hours direct sunlight between 9am and 3pm in mid-winter.

When windows are sized, the average of a room’s floor area has been

taken into consideration to balance daylight and heat gain/loss.

Executive Summary

New subdivisions and developments commonly increase stormwater flows through increasing impermeable areas. There is also the potential for a reduction in the quality of stormwater runoff due to an increase in concentration of pollutants. Each of these is addressed by this report, which integrates Water Sensitive Urban Design (WSUD) elements with the proposed landscape architecture and detailed drainage design. The development proposal at 40 Hall St in Moonee Ponds includes the construction of multi storey building for approximately 450 dwellings, 6 retails shops and recreation areas. It is proposed that the following formal Water Sensitive Urban Design elements be used to treat and retard stormwater run-off from the proposed development, whilst also reducing potable water demand:

40KL worth of Rainwater Tanks to capture 100% of roof water and runoff from level 4 outdoor areas.

Rainwater is Council’s number 1 Alternative Water Source and as such rainwater tanks are to be plumbed to for re-use to 174 toilets, up to level 6

60% of the re-use demand on the tanks can be met 6m2 worth of raingarden is to be provided to treat the outdoor areas immediately to

the east of the building A 6m2 raingarden is to be provided on the within the ground floor landscape area

capturing runoff from the tennis court. A 6m2 raingarden is to be provided on the within the ground floor landscape area

capturing approx. 500m2 of the outdoor area Landscaped outdoor areas on the Ground Floor and Level 4 minimise the overall

impervious area. Water saving fittings and appliance (WELS)

The treatment train as detailed directly improves the quality of water discharged from the site. Model for Urban Stormwater Improvement Conceptualisation (MUSIC) modelling has confirmed that the TP, TN, TSS and Gross Pollutants reduction objectives Moonee Valley City Council and Melbourne Water are achievable.

1 Introduction & Background

Millar Merrigan has been engaged by the developer to assist in the preparation of an integrated storm water management system for a development proposal at 40 Hall St in Moonee Ponds which includes the construction of multi storey building for approximately 450 dwellings, 6 retails shops and recreation areas. This forms the building to be constructed on the site which also includes the property at 34-36 Margaret Street to the west. This strategy has been prepared to deal with the development proposal at 40 Hall Street as a completely separate drainage system to the supplementary development area. For details on 34-36 Margaret Street please refer to the Integrated Stormwater Management Strategy also prepared by Millar Merrigan for this separate site.

It was suggested by Council that MUSIC Modelling be utilised in Lieu of STORM (MW) Analysis for developments on this nature, exceeding 100 bedrooms. This report has provided MUSIC modelling to that effect. Also to be considered are the objectives of the Moonee Valley City Council policies surrounding WSUD which include:

Reduce potable water consumption Re-use Stormwater where possible Reduce pollutant loading in stormwater runoff Protect surface and ground water from stormwater pollution Retard peak stormwater flows Integrate stormwater treatment measures with landscape solution

Manual for MUSIC Version 6

Reference: 18323 V4 – 01/07/2015 6

2 Proposed Strategy

The proposed development is located on approximately half a hectare and has a high fraction impervious due to its relatively large roof to site area ratio and impervious outdoor areas. A combination of WSUD elements are proposed to meet both stormwater quantity and quality objectives. A Model for Urban Stormwater Improvement Conceptualisation (MUSIC) has been prepared showing the improvement to the quality of stormwater discharging from the site. Appendix A contains the WSUD Concept Plan (18323E 01 C1) which is intended to inform the detailed design. The potential treatment opportunities can also be seen in Figure 2 below.

Figure 2 - WSUD Opportunities

The drainage concept proposed is outlined below:


Rainwater tanks are to be plumbed to for re-use to 174 toilets, up to level 6 A series of raingarden is to be provided to treat runoff from the tennis court

and outdoor areas immediately to the east and north of the building, Landscaped outdoor areas on the Ground Floor and Level 4 minimise the

overall impervious area. Water saving fittings and appliance (WELS)

Reference: 18323 V4 – 01/07/2015 7

According to Moonee Valley City Council Hierarchies their number 1 Alternative Water Source is rainwater:

1. Consider roof runoff capture and reuse Rainwater tanks enable roof runoff to be captured and reused locally with minimal infrastructure and treatment requirements. Water can be used for toilet flushing, laundry purposes and garden irrigation. Rainwater harvesting is particularly suited to reducing household and business water demand.

Although rainwater can be used for garden irrigation, washing machines and hot water systems In this case only toilets are to be plumbed for re-use. Council has also set a target for 20% of its water use to be from alternative water sources by 2020. This proposal takes a significant step in this direction. To this end it is proposed that this development take full advantage of its impervious areas, harvesting rainwater, which will in turn reduce the demand on potable water. The Model WSUD guidelines produced by Council & Melbourne Water comments on High Rise development as follows;

High rise urban development is typical of present and future residential growth within inner Melbourne. In high rise apartments, residential water demand is similar to a typical household with the exclusion of garden irrigation. The base buildings require the efficiencies of centralised hot water systems. Stormwater capture from the roof (and possible carpark/plaza/garden area) will reduce stormwater pollution. However the relatively small ratio of surface area to water demand (i.e. number of people) limits this as alternative water source. Therefore the preferred combination for high rise residential development is: • Demand management (option 1) • Reclaimed or greywater for toilet use (option 3).

In this case the re-use demand is appropriately satisfied using rainwater and reclaimed/greywater harvesting is not required

2.1 Detention

The development is required to retard stormwater on site prior to discharge into the existing council drainage system. Typically this storage volume is to be mutually exclusive from the rainwater tank storage for re-use. This premise has been applied here in line with Council and Melbourne Water Policy. Despite this it is noted that the use of rainwater harvesting tanks for re-use will provide a further level of storm attenuation as is shown by the flow reduction outlined in Appendix B. In this location it may be an option to use in-ground tanks, oversized pipes or arches which can be sourced from numerous suppliers. A sealed system should be used if groundwater infiltration is to be minimised.

Reference: 18323 V4 – 01/07/2015 8

2.2 Water Quality

The Model for Urban Stormwater Improvement Conceptualisation (MUSIC) is a program generated to determine the likely water quality of flows from specified catchment areas. MUSIC modelling has been undertaken to determine the requirements of the treatment train to be positioned around the development. Figure 3 shows the setup of the MUSIC model used and Table 1 shows the treatment train effectiveness alongside the percentage of best practice achieved. See Appendix B for further details.

Figure 3 - MUSIC model

Table 1 - MUSIC Output

Pollutant Objectives Achieved Rating %

Total Suspended Solids (TSS) 80% 80.0% 100%

Total Phosphorus (TP) 45% 63.8% 142%

Total Nitrogen (TN) 45% 65.5% 146%

Gross Pollutants 70% 90.4% 129%

Reference: 18323 V4 – 01/07/2015 9

It is clear that the best practice management objectives for load reduction/retention of TSS, TP and TN will be met using both options. Modelling has been undertaken in line with Melbourne Water Guidelines for the use of MUSIC, utilising parameters and rainfall data characteristic of the Moonee Ponds area.

2.3 Rainwater Tanks

It is proposed that 40KL worth of rainwater tanks be placed on the Basement 1 level towards the eastern end of the site as per Figure 2 and the WSUD Concept Plan (18323E 01 CF). These tanks are designed to capture 100% of the roof area including the runoff from the outdoor landscaped areas of Level 4 and are intended to be used for toilet flushing. Rainwater tanks being plumbed to internal fixtures provides re-use and treatment benefits, and will assist in attenuating flows from the site. First Flush diverters should be used on each of the tanks to minimise the ingress of fine particulates and other contaminants into the tank. The re-use of rainwater from tanks has been modelled in MUSIC. This delivers stormwater treatment through removing water from the drainage system and thus pollutants. In accordance with WSUD Engineer Procedures 2005 re-use has been estimated assuming 20L/day/person. Given that there are approximately 629 bedrooms within the development it is reasonable to assume that there will be approximately 629 occupants. This equates to a total usage of 12.58Kl/day. See Table 2 below. It is also reasonable to assume that given there are to be 581 bathrooms; there will also be 581 toilets. The re-use system will circulate rainwater up to the 6th floor. As such there will be 174 toilets connected for re-use out of potential 581. Hence, approximately 30% of the total usage is the potential re-use, coming in at 3.774 KL/day. Table 2 – Re-use Calculation

Rainwater Re-use (Toilets) 20 l/day/person

Assumed Total No. Occupants 629 persons

Total Re-use 12.58 KL/day

Re-use demand 3.774 KL/day

The reliability of the tank providing water to the internal users is estimated by MUSIC to achieve 60% which surpasses the minimum 50% recommended by WSUD Engineering Procedures 2005. Refer to Appendix B for output.

2.4 Raingardens

Raingardens, also known as bio-retention basins, provide an opportunity to bring together a variation in traditional drainage within a landscaped feature. Raingardens are an economical and efficient method to improve the quality and reduce the quantity of water leaving a site. These have been adopted as indicated in Figure 2.

Reference: 18323 V4 – 01/07/2015 10

The majority of impervious outdoor areas within the Plaza area immediately to the east of the building are to drain to a total of 6m2 of raingardens which can dispersed as the detailed design requires. Runoff from the proposed tennis court on the ground floor is to be directed west towards a 6m2 section of raingarden placed in close proximity. Approximately 500m2 of the impervious outdoor area on the ground floor is to be drained towards 6m2 of raingarden as the detailed design requires. It is suggested that this could be placed opposite the central entrance on the north side of the building as indicated inFigure 2.

Figure 4 - WSUD areas

The exact location and dimensions of rain gardens are to be determined in the detailed development plans. Care is to be taken to ensure the extended detention water level of the rain garden is below the surrounding impervious areas so that they may drain freely into through the filtration media. Overland flow paths must also be considered to ensure no detriment to downstream properties.

A typical setup can be seen in Figure 5 below and the WSUD Concept Plan (18323E 01 C1). The extended detention depth will force the permeation of water through the sandy loam filter. The system has been conservatively modelled with a low EDD of 0.1m. Coarse to fine sediments are captured at the filters surface whilst soluble nutrients such as nitrogen are taken up by plants through processes of denitrification. Finer suspended solids are captured within the filter media as the

Reference: 18323 V4 – 01/07/2015 11

water percolates through void spaces and decaying root zones. This layer has been specified at 300mm as can be seen in Appendix B. In areas where groundwater infiltration will be an issue it may be necessary to use an impervious liner surrounding the raingarden.

Figure 5 - Raingarden/Bio-retention Concept

Many species of plants are suitable for raingardens including some locally indigenous species. The proposed rain gardens are to be planted in line with the landscape designs which should consider moisture levels, nutrient uptake and upkeep. Regular maintenance and inspections will be required to ensure the longevity of the system. Where trees are to be planted within or in close proximity to raingardens it may be appropriate to partition the tree from the treatment/filtration media so as to avoid damaging the root mass during the periodic changeover of media. This would also be beneficial for tree stability.

2.5 Water Saving Products

The Water Efficiency Labelling and Standards Act (WELS) is Australia's water efficiency labelling scheme that requires certain products to be registered and labelled with their water efficiency. It allows consumers to compare the water efficiency of different products by requiring that certain products have water rating labels at the point of sale or display/advertising. This development is to adopt water efficient appliances and fittings with labelling and standards in accordance with the WELS scheme to further reduce potable water consumption. It is recommended the following WELS Ratings be adhered to as a minimum: Table 3 - WELS Rating recommendations

Fixture WELS Rating

Basins 5 Stars

Showers 3 Stars

Toilets 5 Stars

Reference: 18323 V4 – 01/07/2015 12

2.6 Groundwater

Council’s WSUD Guidelines for groundwater deals with the impact of groundwater on site discharge practices (as well as aquifer recharge and recovery). Council’s management principles for groundwater are:

Groundwater quantity – over the long term, there is to be no net change in the water quantity

Groundwater quality – water injected is to be of equivalent or greater quality to the receiving groundwater.

The existing site sees a large expanse of sealed carpark which is also minimising the migration of surface water into the soil strata. The development proposes a very high impervious percentage, which is no different to the existing situation, thereby minimising the infiltration of surface water into the subsurface soil strata from the site itself. A geotechnical engineer should be engaged to properly assess soil conditions and to assist in structural designs.

Reference: 18323 V4 – 01/07/2015 13

3 Conclusion & Recommendations

The adoption of the drainage strategy outlined in this report will ensure the BPEMG requirements to treat and retard flows are met. MUSIC modelling has been undertaken proving these targets are achievable. Items 1 (site layout) & 2 (WSUD report) of the Council Clause 22.03 Application Requirements are also satisfied by this report. Detailed design, site management and maintenance plans are to be provided as part of the permit conditions in accordance with Clause 22.03.

The key points of the drainage strategy are:

40KL worth of Rainwater Tanks to capture 100% of roof water and runoff

from level 4 outdoor areas. Rainwater is Council’s number 1 Alternative Water Source and as such

rainwater tanks are to be plumbed to for re-use to 174 toilets, up to level 6 60% of the re-use demand on the tanks can be met 6m2 worth of raingarden is to be provided to treat the outdoor areas

area capturing approx. 500m2 of the outdoor area Landscaped outdoor areas on the Ground Floor and Level 4 minimise the


The Water Sensitive Urban Design elements proposed require minimal care and maintenance and will operate effectively to remove pollutants and retard stormwater flows. For rainwater harvesting, Moonee Valley City Council applies the risk management framework set out in the Model WSUD Guidelines. The proposed strategy is in compliance with the objectives of this risk management framework.

1 Introduction & Background

Millar Merrigan has been engaged by the developer to assist in the preparation of an integrated storm water management system for a development proposal at 34-36 Margaret Street in Moonee Ponds which includes the construction of multi storey building for approximately 176 dwellings, and links to retail shops and recreation areas. This forms the building to be constructed on the site which also includes the property at 40 Hall Street to the east. This strategy has been prepared to deal with the development proposal at 34-36 Margaret Street as a completely separate drainage system to the supplementary development area. For details on 40 Hall Street please refer to the Integrated Stormwater Management Strategy also prepared by Millar Merrigan for this separate site.

It was suggested by Council that MUSIC Modelling be utilised in Lieu of STORM (MW) Analysis for developments on this nature, exceeding 100 bedrooms. This report has provided MUSIC modelling to that effect. Also to be considered are the objectives of the Moonee Valley City Council policies surrounding WSUD which include:

Reduce potable water consumption Re-use Stormwater where possible Reduce pollutant loading in stormwater runoff Protect surface and ground water from stormwater pollution Retard peak stormwater flows Integrate stormwater treatment measures with landscape solution

2 Proposed Strategy

The proposed development is located on approximately half a hectare and has a high fraction impervious due to its relatively large roof to site area ratio and impervious outdoor areas. A combination of WSUD elements are proposed to meet both stormwater quantity and quality objectives. A Model for Urban Stormwater Improvement Conceptualisation (MUSIC) has been prepared showing the improvement to the quality of stormwater discharging from the site. Appendix A contains the WSUD Concept Plan (18323E 01 C1) which is intended to inform the detailed design. The potential treatment opportunities can also be seen in Figure 2 below.

Figure 2 - WSUD Opportunities

The drainage concept proposed is outlined below:



55% of the re-use demand on the tanks can be met Landscaped outdoor areas on the Ground Floor and Level 6 minimise the


According to Moonee Valley City Council Hierarchies their number 1 Alternative Water Source is rainwater:

1. Consider roof runoff capture and reuse Rainwater tanks enable roof runoff to be captured and reused locally with minimal infrastructure and treatment requirements. Water can be used for toilet flushing, laundry purposes and garden irrigation. Rainwater harvesting is particularly suited to reducing household and business water demand.

Although rainwater can be used for garden irrigation, washing machines and hot water systems In this case only toilets are to be plumbed for re-use. Council has also set a target for 20% of its water use to be from alternative water sources by 2020. This proposal takes a significant step in this direction.

Reference: 18323 V3 – 1/07/2015 7

To this end it is proposed that this development take full advantage of its impervious areas, harvesting rainwater, which will in turn reduce the demand on potable water. The Model WSUD guidelines produced by Council & Melbourne Water comments on High Rise development as follows;

High rise urban development is typical of present and future residential growth within inner Melbourne. In high rise apartments, residential water demand is similar to a typical household with the exclusion of garden irrigation. The base buildings require the efficiencies of centralised hot water systems. Stormwater capture from the roof (and possible carpark/plaza/garden area) will reduce stormwater pollution. However the relatively small ratio of surface area to water demand (i.e. number of people) limits this as alternative water source. Therefore the preferred combination for high rise residential development is: • Demand management (option 1) • Reclaimed or greywater for toilet use (option 3).

In this case the re-use demand is appropriately satisfied using rainwater and reclaimed/greywater harvesting is not required

2.1 Detention

The development is required to retard stormwater on site prior to discharge into the existing council drainage system. Typically this storage volume is to be mutually exclusive from the rainwater tank storage for re-use. This premise has been applied here in line with Council and Melbourne Water Policy. Despite this it is noted that the use of rainwater harvesting tanks for re-use will provide a further level of storm attenuation as is shown by the flow reduction outlined in Appendix B. In this location it may be an option to use in-ground tanks, oversized pipes or arches which can be sourced from numerous suppliers. A sealed system should be used if groundwater infiltration is to be minimised.

2.2 Water Quality

The Model for Urban Stormwater Improvement Conceptualisation (MUSIC) is a program generated to determine the likely water quality of flows from specified catchment areas. MUSIC modelling has been undertaken to determine the requirements of the treatment train to be positioned around the development. Figure 3 shows the setup of the MUSIC model used and Table 1 shows the treatment train effectiveness alongside the percentage of best practice achieved. See Appendix B for further details.

Reference: 18323 V3 – 1/07/2015 8

Figure 3 - MUSIC model

Table 1 - MUSIC Output

Pollutant Objectives Achieved Rating %

Total Suspended Solids (TSS) 80% 80.6% 101%

Total Phosphorus (TP) 45% 78.5% 174%

Total Nitrogen (TN) 45% 77.4% 172%

Gross Pollutants 70% 91.5% 130%

It is clear that the best practice management objectives for load reduction/retention of TSS, TP and TN will be met using both options. Modelling has been undertaken in line with Melbourne Water Guidelines for the use of MUSIC, utilising parameters and rainfall data characteristic of the Moonee Ponds area.

2.3 Rainwater Tanks

It is proposed that 30KL worth of rainwater tanks be placed on the Basement 1 level towards the wester end of the site as per Figure 2 and the WSUD Concept Plan (18323E 01 CF). This exact location is to be confirmed during detailed design and may be shifted as required. These tanks are designed to capture 100% of the roof area including the runoff from the outdoor landscaped areas of Level 6 and are intended to be used for toilet flushing. Rainwater tanks being plumbed to internal fixtures provides re-use and treatment benefits, and will assist in attenuating flows from the site. First Flush diverters should be used on each of the tanks to minimise the ingress of fine particulates and other contaminants into the tank. The re-use of rainwater from tanks has been modelled in MUSIC. This delivers stormwater treatment through removing water from the drainage system and thus pollutants. In accordance with WSUD Engineer Procedures 2005 re-use has been estimated assuming 20L/day/person. Given that there are approximately 239 bedrooms within the development it is reasonable to assume that there will be approximately 239 occupants. This equates to a total usage of 4.78Kl/day. See Table 2 below.

Reference: 18323 V3 – 1/07/2015 9

It is also reasonable to assume that given there are to be 214 bathrooms; there will also be 214 toilets. The re-use system will circulate rainwater up to the 6th floor. As such there will be 151 toilets connected for re-use out of potential 214. Hence, approximately 48% of the total usage is the potential re-use, coming in at 2.294 KL/day. Table 2 – Re-use Calculation

Rainwater Re-use (Toilets) 20 l/day/person

Assumed Total No. Occupants 239 persons

Total Re-use 4.78 KL/day

Re-use demand 2.294 KL/day

The reliability of the tank providing water to the internal users is estimated by MUSIC to achieve 55% which surpasses the minimum 50% recommended by WSUD Engineering Procedures 2005. Refer to Appendix B for output. These tanks could potentially be positioned within the Basement 1 level or as specified by the detailed engineering design.

2.4 Raingardens

Raingardens, also known as bio-retention basins, provide an opportunity to bring together a variation in traditional drainage within a landscaped feature. Raingardens are an economical and efficient method to improve the quality and reduce the quantity of water leaving a site. These have been adopted as indicated the Integrated Stormwater Management Strategy prepared for 40 Hall Street but are not required for 34-35 Margaret Street.

2.5 Water Saving Products

The Water Efficiency Labelling and Standards Act (WELS) is Australia's water efficiency labelling scheme that requires certain products to be registered and labelled with their water efficiency. It allows consumers to compare the water efficiency of different products by requiring that certain products have water rating labels at the point of sale or display/advertising. This development is to adopt water efficient appliances and fittings with labelling and standards in accordance with the WELS scheme to further reduce potable water consumption. It is recommended the following WELS Ratings be adhered to as a minimum: Table 3 - WELS Rating recommendations

Fixture WELS Rating

Basins 5 Stars

Showers 3 Stars

Toilets 5 Stars

2.6 Groundwater

Council’s WSUD Guidelines for groundwater deals with the impact of groundwater on site discharge practices (as well as aquifer recharge and recovery). Council’s management principles for groundwater are:

Groundwater quantity – over the long term, there is to be no net change in the water quantity

Groundwater quality – water injected is to be of equivalent or greater quality to the receiving groundwater.

The existing site sees a large expanse of sealed carpark which is also minimising the migration of surface water into the soil strata. The development proposes a very high impervious percentage, which is no different to the existing situation, thereby minimising the infiltration of surface water into the subsurface soil strata from the site itself. A geotechnical engineer should be engaged to properly assess soil conditions and to assist in structural designs.

3 Conclusion & Recommendations

The adoption of the drainage strategy outlined in this report will ensure the BPEMG requirements to treat and retard flows are met. MUSIC modelling has been undertaken proving these targets are achievable. Items 1 (site layout) & 2 (WSUD report) of the Council Clause 22.03 Application Requirements are also satisfied by this report. Detailed design, site management and maintenance plans are to be provided as part of the permit conditions in accordance with Clause 22.03.

The key points of the drainage strategy are:

30KL worth of Rainwater Tanks to capture 100% of roof water and runoff from

level 6 outdoor areas. Rainwater is Council’s number 1 Alternative Water Source and as such

rainwater tanks are to be plumbed to for re-use to 151 toilets, up to level 6 55% of the re-use demand on the tanks can be met Landscaped outdoor areas on the Ground Floor and Level 6 minimise the


The Water Sensitive Urban Design elements proposed require minimal care and maintenance and will operate effectively to remove pollutants and retard stormwater flows. For rainwater harvesting, Moonee Valley City Council applies the risk management framework set out in the Model WSUD Guidelines. The proposed strategy is in compliance with the objectives of this risk management framework.
