Introduction The Moreland Stormwater Management Plan (SWMP) provides a strategic framework to protect stormwater quality throughout the municipality, thereby protecting local and downstream waterways that receive stormwater run-off. The SWMP has been developed in accordance with the Urban Stormwater Best Practice Environmental Management Guidelines (Stormwater Committee, 1999), utilising an integrated approach involving the various organisations having a role in stormwater management. Volume 1 of the SWMP provides a summary of the key stormwater issues in the municipality and recommendations on how to respond to these issues. Volume 2 contains detailed background information to support the strategic recommendations contained in Volume 1. The two volumes have been designed to act as ‘stand-alone’ documents and therefore contain some similar sections where appropriate. The aim of the Moreland Stormwater Management Plan is to improve the environmental management of stormwater in the City of Moreland in order to protect and enhance local and downstream waterways that receive stormwater run-off. This aim is supported by the strategies and actions contained in the SWMP. The SWMP is a component of a long-term vision for the City of Moreland, which includes water sensitive urban development. This comprises development in which natural hydrological features are retained, water sensitive urban design principles are consistently utilised, and water conservation and recycling technologies are built into buildings and homes. 1.1 What is Stormwater Run-off? Our cities are characterised by extensive areas covered by hard, impervious surfaces, such as bitumen, concrete and buildings. This aspect of urbanisation has major and far-reaching effects on local hydrology. In particular, much less water can be absorbed by soils and there is less vegetation to use and retain run-off. As a result of increased amounts of urban run-off during storm events, flooding and overloading of the sewerage system can occur. The potential for the incidence of urban flooding to increase in the future also needs to be assessed in light of such factors as ageing infrastructure, urban intensification and climate change. The traditional response to managing stormwater run-off was to focus primarily on the efficient conveyance of stormwater away from urban environments. This focus on stormwater conveyance has serious consequences on environments receiving stormwater run-off. Effects include increased scouring of streambeds and banks, down-cutting of channels and loss of aquatic and riparian vegetation. In addition, the activities and land uses occurring in the urban environment release a range of pollutants that are efficiently transported by stormwater run-off to receiving environments. Common pollutants include heavy metals and oils from major roads, D:\687303898.doc Page 1 Moreland Stormwater Management Plan: Vol 1 - The Strategy sediments from building and construction sites, and various contaminants from household related activities (including paint residues, dog faeces and litter). While individually these contaminants may not have significant impacts, their cumulative effects are serious threats to the quality of waterways. In contrast to the traditional approach to stormwater described above, the current focus of stormwater management is on measures to store and retain stormwater, trap and remove gross pollutants, and improve the quality of stormwater discharged to receiving waterway environments. Furthermore, stormwater is increasingly recognised as a valuable resource that has the capacity to be harvested, thereby reducing the overall amount of stormwater run-off as well as reducing demands on water supply reservoir. 1.2 Why Prepare a Stormwater Management Plan? The City of Moreland has a frontage to many waterways, including the Merri, Moonee Ponds, Edgars and Merlynston Creeks. In addition to performing important drainage functions, these waterways provide the community with a range of other values, including the provision of habitats for a variety of plant and animal species, recreational opportunities, sites of cultural significance, and increased market value of adjacent properties. These waterways and their associated values have the potential to be seriously degraded by stormwater run-off. Council has a long-standing commitment to natural resource conservation and environmental protection, including the rehabilitation and maintenance of the local waterways. In addition to actively supporting organisations such as the Merri Creek Management Committee and the Moonee Ponds Creek Coordination Committee, Council has already developed a number of strategies that either directly or indirectly address issues related to the quality of local waterways (see Section 4.2). The SWMP is a key initiative of Council that strengthens and builds on these existing strategies. Importantly, the SWMP is part of a metropolitan wide program initiated in 1998 by Melbourne Water, EPA and MAV to facilitate the improved environmental management of stormwater through development of stormwater management plans by councils across the greater Melbourne area. 1.3 Purpose of the Moreland Stormwater Management Plan The purpose of the Moreland Stormwater Management Plan is to: identify current responsibilities, practices, procedures and obligations for stormwater management in the City of Moreland; identify the main values of receiving water environments and the main threats contributing to poor water quality; articulate objectives to protect and enhance water quality; and outline strategies aimed at protecting and improving the quality of stormwater and receiving water environments. D:\687303898.doc Page 2 Moreland Stormwater Management Plan: Vol 1 - The Strategy 2. Development of the Moreland Stormwater Management Plan The Moreland Stormwater Management Plan (SWMP) has been prepared in accordance with the methodology contained in the Urban Stormwater Best Practice Environmental Management Guidelines (Stormwater Committee, 1999), henceforth referred to as the Guidelines. 2.1 Methodology The preparation of the SWMP entailed a three-phase process: The first phase of the project involved meeting with key stakeholders, data collection, and field inspections. The second phase focused on the identification of the environmental, amenity, economic, hydraulic and cultural values of the waterways, and the land use activities posing a threat to these values. An assessment and ranking process of this information was then undertaken to confirm the key threats to stormwater receiving environments and establish priorities for addressing those threats. The final phase of the project involved the identification of management options to address prioritised stormwater quality issues, including actions, responsibilities and timing. The process is summarised in Table 2.1 below. Table 2.1: The Stormwater Management Planning Process Stage Consultation Stage 1: Preliminary Activities 1. Establish commitment to the project 2. Agree to project framework and scope 3. Define problems and information requirements Stakeholder briefing Interview stakeholders Undertake site inspections Stakeholder workshop to discuss issues Working group meeting to confirm values and threats Stakeholder workshop to review priorities and potential actions Stage 2 Risk Assessment 1. Identify stormwater threats 2. Identify values of receiving environments 3. List stormwater issues/activities in order of importance (i.e., threat x value = priority) Stage 3 Development of Stormwater Management Plan 1. Consider strategy options to address priority risks 2. Develop list of recommendations based on cost effectiveness, capability, opportunity 3. Establish responsibilities, costs and review Working group meeting to review recommendations D:\687303898.doc Page 3 Moreland Stormwater Management Plan: Vol 1 - The Strategy 2.2 Stakeholder Involvement PPK Environment & Infrastructure was commissioned by Council to develop the Moreland Stormwater Management Plan in close consultation with Council, Melbourne Water, and Environment Protection Authority Victoria (EPA). Council’s Conservation Planner was responsible for overall project management and final editing of the document. A number of other organisations were involved in the preparation of the SWMP, including the Merri Creek Management Committee and the Moonee Ponds Creek Coordination Committee. Overall development of the SWMP was directed by a Steering Committee consisting of representatives of Council and a representative of Melbourne Water. Regular ongoing input and feedback to the SWMP was provided by the project Working Group. The individuals involved in these groups are presented in Table 2.2.

The risk of losing values as a result of these stormwater related threats depends on the scale or severity of the threat and the sensitivity of the receiving environments to that threat. The aim of this process was to identify areas where the risk of damage is greatest. This process is represented in Figure 2.1 Figure 2.1: Determining Risk Threat Value from stormwater pollution or flows: - scale or severity - likelihood or frequency of receiving environment: - sensitivity; and - significance Threat x Value RISK of losing environmental/amenity value The risk assessment process is based on the approach prescribed in the Guidelines (Stormwater Committee, 1999), involving the following components: undertaking field investigations, literature reviews and discussions to identify discrete reaches along the main waterways and catchments to define ‘investigation’ areas; undertaking field investigations, literature reviews and discussions to identify values along the waterways; identifying potential threats (i.e., activities and actions that do or could have an impact on stormwater quality); confirming the threats and values with stakeholders; considering the transmission efficiency of the drainage system to identify the potential likelihood and ease that a potential threat could impact on stormwater values (i.e., how readily a contaminant could be transported into the waterways); ranking the threats and values on a scale of high, medium and low and confirming these values with stakeholders; D:\687303898.doc Page 5 Moreland Stormwater Management Plan: Vol 1 - The Strategy correlating the threats and values to identify the levels of risk on a scale of high, medium and low; and transferring the risks to priorities (e.g., 1=high, 2=medium and 3=low) and confirming these priorities with stakeholders. As discussed above, the protection and enhancement of waterway values is the overriding objective of the SWMP. For the purposes of the SWMP, waterway values are grouped into five categories, as indicated in Table 2.3. Table 2.3: Stormwater Values Value Environment Amenity Economic Hydraulic Cultural Category Examples Physical Natural stream profile, stable stream banks Ecological Stands of intact remnant vegetation, large habitat area Recreation Areas where people can walk, cycle, picnic or play sport Landscape Areas that are acknowledged for their picturesque landscape Indirect Areas that add value to adjacent properties such as suburban lakes, parks and recreational facilities Flood Protection Areas that provide an important drainage function and provide protection from flooding Significance Areas that contain sites which have been recorded as being of cultural and heritage significance (Aboriginal and European) One of the first steps in the risk assessment process involved assessing receiving water environments to identify their associated values. The ranking criteria utilised in this assessment are listed in Table 2.4. It should be noted that the assessment of cultural values was limited in scope as it is based on recorded sites, which are low in number. The Moreland City Plan (Municipal Strategic Statement) identifies the need for additional strategic work to be undertaken to increase the level of knowledge of cultural heritage sites in the municipality. Table 2.4: Criteria for Ranking Values Value Environment (physical) Environment (ecological) Amenity (recreation) Amenity (landscape) Ranking Criteria H: Natural channel and stream form and native riparian vegetation M: Modified channel stream form and scattered riparian vegetation L: Concrete lined channel and little or no riparian vegetation H: Intact stand of remnant vegetation and important fauna habitat M: Intact vegetation corridor linking fauna habitat areas L: Little or no habitat value H: Community open space/parks within the stream corridor area with high levels of use M: Linear reserves with bike/walking paths contained within the stream corridor L: No public access or recreation facilities within the stream corridor H: Open space with vegetation cover within the stream corridor area M: Linear reserves with some vegetation contained within the stream corridor L: Limited reserve and vegetation cover within the stream corridor D:\687303898.doc Page 6 Moreland Stormwater Management Plan: Vol 1 - The Strategy Value Economic Hydraulic (flood protection) Cultural Ranking Criteria H: Significant value adding to adjoining private property M: Positive impact on value adding to adjoining property L: Neutral or negative impact on property values to adjoining property H: High levels of flood protection provided by the reach’s stream and floodplain and/or flood management assets. M: Moderate levels of flood protection provided by the reach’s stream and floodplain and/or flood management assets L: Low levels of flood protection H: Sites within the waterway corridor assessed as having high educational or cultural/heritage significance in research reports M: Other identified cultural/heritage or educational sites documented L: Surveyed sites with no cultural/heritage or educational values or unsurveyed sites with only potential heritage values. The identification of threats was another key component of this stage of the risk assessment. Threats were assessed in terms of whether they would result in sedimentation (e.g. sand and soil), litter (e.g. rubbish and dumping), nutrients (e.g. fertilisers), pathogens (e.g. sewage and bacteria), toxicants (e.g. herbicides, pesticides, petrol and oil), de-oxygenating material (e.g. leaf matter) and changes in flow (e.g. increase in the volume and velocity of stormwater). The next phase of the risk assessment process involved reviewing the identified stormwater-related threats in order to determine the potential risks to the values of receiving environments and priorities for management responses. The main considerations in this phase were: the transmission efficiency of drains carrying the pollution or flow threats; the significance of receiving water values; and the sensitivity of those values to the threats identified. This process of determining priorities is illustrated in Figure 2.2.

City of Moreland – Context The City of Moreland was formed in 1994 following the amalgamation of the former Cities of Coburg, Brunswick and part of the former City of Broadmeadows. This section provides an overview of the key physical characteristic of the municipality. For further details refer to Volume 2. 3.1 Location Located in Melbourne’s northern region, the City of Moreland has an area of approximately 51 square kilometres, and is bounded by the Merri Creek and Elizabeth Street to the east and the Moonee Ponds Creek to the west. Park Street, Brunswick forms the City’s southern boundary, and the Western Ring Road forms the northern boundary. 3.2 Land Use and Development The City of Moreland's population in the year 2000 was estimated to be 137,055 people. The municipality is largely developed with a diverse pattern of land use. The area south of Moreland Road is characterised by a mixture of residential, industrial and commercial land use. The central and northern areas of the municipality are principally residential, except for the major retail centres of Glenroy and Coburg, and significant areas of manufacturing industry in North Coburg and Fawkner (Moreland Municipal Strategic Statement, 2000). Strip shopping, office and other commercial activities are particularly concentrated along Sydney Road, Lygon Street and Melville Road. Major areas of open space in the municipality include the Northern Golf Course and Northern Memorial Park in Glenroy, Gilpin and Clifton Parks in Brunswick, and significant tracts of linear open space along the Merri Creek and Moonee Ponds Creek. Figure 3.1 shows the key physical characteristics and land uses of the City of Moreland. D:\687303898.doc Page 9 Moreland Stormwater Management Plan: Vol 1 - The Strategy Figure 3.1: City of Moreland D:\687303898.doc Page 10 Moreland Stormwater Management Plan: Vol 1 - The Strategy 3.3 Waterways As a developed urban municipality, the City of Moreland has a well-established drainage system. Stormwater is collected via various sizes of drains and pipes and ultimately discharged into one of the open waterways in the municipality. Sydney Road broadly divides the City of Moreland into two main drainage catchments. The eastern section drains to the Merri Creek, while the western section drains to the Moonee Ponds Creek. In total, the Merri Creek is about 80 kilometres long and the catchment drains an area of slightly less than 400 square kilometres. Prior to entering the City of Moreland, the creek flows between the Cities of Whittlesea and Hume. The Merri Creek is joined from the east by Central Creek in Reservoir, then by the Merlynston Creek north of Carr Street in North Coburg. The Merri Creek then flows into Coburg Lake and, between Newlands Road and Murray Road, is joined by the Edgars Creek. The Moonee Ponds Creek is another of the northern tributaries of the Yarra River, with a catchment covering an area of 139 square kilometres. After entering the urban fringe, the creek flows through the suburbs of Glenroy, Pascoe Vale, Strathmore, Essendon, Brunswick, Ascot Vale, Kensington and North Melbourne. Moonee Ponds Creek joins the Yarra River at Appleton Dock. The majority of the creek’s length along the western boundary of the municipality has been altered for flood management purposes. The most significant change to the Moonee Ponds Creek occurred in the 1960s with the construction of the Tullamarine Freeway. As a result of freeway construction works, the creek was realigned in three sections and concrete-lined from upstream of Pascoe Vale Road to Mt Alexander Road. The management of the stormwater system, waterway corridors and their components involves a variety of agencies. Melbourne Water manages the waterways and associated beds and banks, and owns some related land beyond the banks. Council and neighbouring councils (Darebin, Hume, Moonee Valley and Melbourne) manage open space land beyond the top of the stream banks, which are often held as reserves. EPA has a regulatory role through the development and administration of policies, including State Environment Protection Policies. The Yarra Catchment Implementation Committee has a role under the Catchment and Land Protection Act. The Merri Creek Management Committee and Moonee Ponds Creek Coordination Committee are involved in assisting with the management of the waterway corridors, although they have no statutory powers or responsibilities. All are important stakeholders within the spectrum of waterway corridor management. The main waterways in the City of Moreland are shown in Figure 3.2. To facilitate the development of targeted management strategies, stormwater receiving environments were segmented into locations based on similarities with respect to their environmental characteristics, the form of the waterway at that location, and the type of surrounding land use. These segmented locations (i.e. subcatchments) are illustrated in Figure 3.2. Furthermore, the Moonee Ponds and Merri Creeks were divided into the following reaches: D:\687303898.doc Page 11 Moreland Stormwater Management Plan: Vol 1 - The Strategy a) Reaches of the Moonee Ponds Creek: MO1 - from the Western Ring Road to Devereaux Street, Glenroy; MO2 - Devereaux Street to Pascoe Vale Road, Pascoe Vale; MO3 - Pascoe Vale Road to Morrow Street, Pascoe Vale South; MO4 – Reynard Street to Moreland Road; and MO5 - Moreland Road to Park Street. b) Reaches of the Merri Creek: ME1 - Mahoneys Road to Hare Street, Fawkner; ME2 - Hare Street to Bakers Road, Coburg North; ME3 - Bakers Road to Bell Street, Coburg; and ME4 - Bell Street to May Street, Brunswick East.

Stormwater Management Framework Melbourne Water is the regional drainage authority and therefore plays a major role in stormwater management. Council also plays an integral role in stormwater management as the provider and manager of the local drainage system. There are a number of other State Government agencies and local organisations that are stakeholders in stormwater management. This section provides a summary of these stakeholders and their activities, as well as a summary of existing initiatives that are in place to assist in the management of stormwater in the City of Moreland. Further details are included in Volume 2. 4.1 Roles and Responsibilities 4.1.1 Statutory Authorities Those with key responsibilities for stormwater management in the City of Moreland include the following: Moreland City Council (Council) – Council has maintenance responsibilities for local drains (generally catchments <60 hectares), and is responsible for waste collection, litter control, street cleansing, park maintenance and associated activities. It is also primarily responsible for undertaking forward planning and administering development control through planning permit assessment, building permit assessment and local laws. Melbourne Water Corporation (Melbourne Water) – Melbourne Water has responsibility for managing regional drainage and flood mitigation (generally catchments >60ha), waterway management, water quality protection and the consideration of planning matters referred under Section 55 of the Planning and Environment Act (1987). Environment Protection Authority Victoria (EPA) – EPA is responsible for the protection of the quality of Victoria’s environment through the administration of the Environment Protection Act (1970), the development of State Environmental Protection Policies, enforcement and the establishment of programs to encourage the use of best practices in achieving required environmental standards. It is also responsible for administering the Victorian Stormwater Action Program. Department of Infrastructure (DoI) - DoI is responsible for developing the State planning system and policies, including the framework in which councils develop and implement their own planning schemes. In addition, it incorporates the Office of Local Government, Building Control Commission, and is responsible for the planning and coordination of major infrastructure, including transport (through agencies such as VicRoads and the Public Transport Corporation). Victorian Stormwater Advisory Committee (VSAC) – Formerly known as the Stormwater Committee, VSAC was established in 2000 to guide the implementation D:\687303898.doc Page 14 Moreland Stormwater Management Plan: Vol 1 - The Strategy of the Victorian Stormwater Action Program, including the allocation of $22.5m to councils over three years (1999/2000 – 2001/2002) for urban stormwater projects. Yarra Catchment Implementation Committee – The committee is one of five catchment implementation committees established by the Catchment & Land Protection Board across the Port Phillip Region. Its function is to implement the Yarra Catchment Action Plan (1999), which addresses issues including water pollution, loss of native vegetation, waterway degradation, soil degradation and flooding issues across the catchment. 4.1.2 Non-Statutory Bodies Merri Creek Management Committee (MCMC) – An incorporated association, MCMC is a voluntary collaboration between key agencies along the Merri Creek corridor which, through the employment of staff, seeks to add value to the management efforts of its members. Formed in 1989, its primary purpose is to ensure the environmentally sensitive development and maintenance of the Merri Creek and adjoining catchment areas. Moonee Ponds Creek Coordination Committee (MPCCC) – MPCCC is currently an unincorporated association operating according to a Memorandum of Understanding between signatory parties, including Council. MPCCC focuses on promoting the restoration and revegetation of the Moonee Ponds Creek corridor. 4.2 Policies And Practices Key legislative requirements, policies and practices that have direct and/or indirect impacts on stormwater management in the City of Moreland include the following: Victoria Planning Provisions (DoI, 2000) – The Victoria Planning Provisions form the basis of all planning schemes, including the Moreland Planning Scheme, through the identification of standard zones, overlays, provisions and definitions. It also addresses strategic planning issues of State importance. Section 15 of the State Planning Policy Section (SPPF) includes a policy regarding the protection of water quality. State Environment Protection (Policy Waters of Victoria) (Vic Govt, 1998) Developed by the EPA under the Environment Protection Act (1970) the SEPP seeks to protect water quality across the State. It includes a number of schedules, including Schedules F6 and F7, which prescribe objectives and standards for water quality in Port Phillip Bay and the Yarra catchment respectively. Specifically, the schedules require relevant agencies (including councils) to ensure that contaminants in run-off, including litter, are prevented from adversely affecting beneficial uses. Port Phillip and Westernport Regional Catchment Strategy (Port Phillip CALP, 1998) - The strategy is a major mechanism through which the CALP Board continues to supply advice to the State Government on the condition of land and water in the region. The strategy includes an action to develop and implement the Stormwater Initiative and complete stormwater management plans for all councils in the metropolitan area by 2003. D:\687303898.doc Page 15 Moreland Stormwater Management Plan: Vol 1 - The Strategy Yarra Catchment Action Plan (EPA, 1999) - The plan identifies the Merri Creek subcatchment as one of six priority sub-catchments for action. It also generally identifies the need for stormwater management plans. Best Practice Environmental Management Guidelines for Urban Stormwater (Stormwater Committee, 1999) - Developed by Melbourne Water and the Stormwater Committee, the Guidelines establish stormwater quality objectives to assist in determining the level of stormwater management necessary to meet the SEPP (Waters of Victoria) requirements. The Guidelines also include a methodology for councils to follow in developing stormwater management plans. Moreland Planning Scheme (Moreland City Council, 2000b) - Developed in accordance with the Victoria Planning Provisions, the new scheme includes state planning policies, local planning policies, a municipal strategic statement, as well as land use zone controls and overlay provisions (including Environmental Significance Overlays for Moonee Ponds and Merri Creeks). The local section incorporating the Municipal Strategic Statement and Local Policy identifies long-term directions for land use and development in the City of Moreland, including protecting water quality and the overall amenity of waterway environs. While the scheme contains a number of provisions that refer to stormwater related issues, there is no overall policy relating specifically to stormwater. Standard Permit Conditions – Council has adopted a suite of standard planning permit conditions (refer to Volume 2 for details), several of which relate to stormwater matters, including stormwater drainage requirements, requirements for oil and silt traps and lot drainage requirements. However, there are no specific stormwater conditions. Local Laws - Council has developed a number of local laws including those relating to the use of public places, littering, responsible animal management and the removal of dog excrement from public places (see Volume 2 for details). However, there are no specific stormwater laws, nor any relating to sediment control or off-site impacts of construction. Moreland Litter Trap Action Plan (Allison Partners, 1998) – Commissioned by Council, the plan includes an analysis of the sources of litter within the municipality and the structural litter trap measures that should be implemented to reduce litter loads to the Moonee Ponds and Merri Creeks. Moreland Waste Management Strategy (Moreland City Council, 1998e) – The strategy outlines a plan for the improved management and reduction of solid wastes. It stresses the importance of preventing litter from entering waterways and recommends a range of measures to minimise wastes in the municipality. Moreland Litter Strategy (Moreland City Council, 1997c) – The strategy was prepared within the broad framework of Victoria’s Litter Reduction Strategy and is a ‘Council and Community Plan for reducing litter’ in the City of Moreland. It recommends a range of measures to reduce littering. D:\687303898.doc Page 16 Moreland Stormwater Management Plan: Vol 1 - The Strategy 5. Stormwater Values & Threats in the City of Moreland Effective stormwater management requires an assessment of waterway values and the stormwater related threats to those values in order to identify the greatest risks and priorities for future action. The following provides a summary of the stormwater values, threats and priorities in the City of Moreland. Further details are contained in Volume 2. 5.1 Receiving Environment Values In order to develop strategies to protect and enhance the values of receiving water environments, the key values of receiving environments were identified and ranked according to the significance of their attributes. The identification of values is based on information collected during the preliminary stages of the project. A detailed discussion of this information is included in Volume 2. It is important to identify the full range of values associated with stormwater receiving environments so that appropriate management techniques can be developed to respond to the needs of specific areas. To aid in the assessment, values have been grouped into the five following categories: environmental, amenity, economic, hydraulic and cultural values (presented earlier in Table 2.3). It should be noted that in this exercise values were assessed as a current snap shot of existing conditions and that changes to values over time are recognised as inevitable. This means that while potential values (i.e. future values) cannot be estimated or assessed here, they are by no means ignored or discounted. Instead, it is recognised that an essential element of the future review of the SWMP will be a re-consideration of values (and threats) to take into account a contemporary picture of elements which constitute the risk assessment process. That contemporary assessment of values will be key to determining appropriate actions and their priority in the future review of the SWMP. Moonee Ponds and Merri Creeks are the ultimate receiving waters within the City of Moreland, as the other waterways in the municipality are tributaries which flow into these creeks. The values both within and along the creeks vary considerably, as demonstrated in Figure 5.1 and Table 5.1. Those areas identified as having the highest level of significance include: Westbreen Creek generally adjacent the Northern Golf Course in Glenroy; Merri Creek generally between Parker Reserve and Bell Street; Jackson Reserve and Edgars Creek; and Merlynston Creek generally adjacent to Wallace Reserve, Glenroy. In addition to high amenity and economic values, each of these locations is considered to have either high environmental or cultural values.

D:\687303898.doc Page 19 Moreland Stormwater Management Plan: Vol 1 - The Strategy 5.2 Threats to Receiving Environments 5.2.1 Water Quality Considerable water quality monitoring data has been gathered for Melbourne’s waterways which indicates that water quality is adversely effected by stormwater run-off from urban areas. With respect to the Merri and Moonee Ponds Creeks and their tributaries, water quality data has principally been collated by EPA, Melbourne Water and community groups. Examples of common stormwater related threats, their sources and impacts are presented in Table 5.3. Table 5.3: Common Threats to Stormwater Category Impacts Typical Sources Typical Components Pathogenic organisms Closure of beaches, human infection, illness and disease Sullage, sewer overflows, animals Faecal coliforms, bacteria, viruses Oxygen depleting substances Low dissolved oxygen, odours, stress to aquatic life Sullage, sewer overflows, animal wastes, grass and leaf litter Organic matter Toxicants including metals and salts Bio-accumulation, death of aquatic life Cars, car parks, roads, processing industries, spills, atmospheric deposition Pesticides, herbicides, petroleum products, lead, zinc Sediment, including suspended solids and turbidity Muddy water, siltation, smothering of aquatic life Stream erosion, construction sites, roads, sand transport Silt, sand, gravel, clays Litter Mainly visual, interferes with aquatic life Commercial areas, fast food outlets, plant debris Paper, plastic, leaves, dead vegetation Nutrients Promotes plant and algal growth, bluegreen algal blooms Sullage, sewer overflows, animals, STP discharges Phosphorus and nitrogen Flow Increased volume or velocity of flows can scour or erode receiving waters. Increased freshwater volumes can affect estuarine or marine environments. Increased stormwater runoff Volume, frequency, velocity Source: Pat Condina & Associates, as presented in Stormwater Committee (1999). 5.2.1.1 Merri Creek EPA has monitored one site on the Merri Creek at Cole Street, Coburg and two sites on the Moonee Ponds Creek at Bent Street in Essendon and in Devereaux Street, Oak Park. All sites have failed to meet the SIGNAL score requirements set-down in Schedule F7 of the SEPP for the Waters of Victoria (EPA, 2000). The SIGNAL index is a biotic index that uses the sensitivity of families of aquatic invertebrates to various types of pollutant as a guide to waterway health. There have been more than eleven studies completed on water quality in the Merri Creek system. These include one-off snapshots of the health of the waterway, as D:\687303898.doc Page 20 Moreland Stormwater Management Plan: Vol 1 - The Strategy well as reports based on long-term monitoring over several years, with a focus on physio-chemical rather than biological aspects. The Merri Creek and Environs Strategy (Merri Creek and Environs Steering Committee, 1999) provides an overview of the studies, including Mitchell and Dunn (1993) and others. The strategy indicates that non-point sources of pollution (including urban run-off) are dominant contributors to stormwater pollution in the creek and highlights the following: high levels of heavy metals exist in both Merri and Edgars Creeks; concentrations of nutrients remain high throughout Merri Creek, with the Craigieburn Treatment Plant likely to be a major source; organic pollution has reduced over the past twenty years, but there still appears to be parts of Merri and Edgars Creeks that receive some organic pollution; salinity levels in parts of the Merri Creek often exceed EPA’s objectives (it is not known if this is a natural feature of the catchment or a result of rising water tables); and turbidity, and possibly suspended solids, periodically exceeds EPA objective levels. Finlay, McGann and Roy (1997) undertook a study of the entire length of Merri Creek and concluded that water quality in the Merri and Edgars Creeks generally declines downstream along the waterways. Much of the decline was attributed to changing land use, with upper catchment agricultural areas having high nutrient problems, the ‘industrial areas’ of the stream corridor, particularly around Campbellfield, demonstrating a rise in heavy metal pollution, and the lower residential areas showing some problems possibly associated with inadequate sewerage disposal and diffuse source pollution via the stormwater system. The upper parts of Merri Creek in the City of Moreland are impacted heavily by industrial development within the neighbouring City of Hume. This issue has received particular attention in the City of Hume’s Stormwater Management Plan (Hume City Council, in prep.). Finlay, McGann and Roy (1997) also identified a number of Melbourne Water drains known as sources of pollution, including: Ainslie Road and Somerset Road Drains (heavy metal pollution); and Campbellfield Creek Diversion Drain/Fawkner East Drain. 5.2.1.2 Moonee Ponds Creek Water quality data for Moonee Ponds Creek has been collected since 1977 at a site adjacent to Mount Alexander Road. The data indicates that the water quality has improved, particularly for E-Coli and BOD (biological oxygen demand) levels. This improvement has been attributed to the implementation of the sewering program. While this is a positive outcome, the creek is still subject to a number of threats. The most recent study (Pettigrove and Ho, 1996) describes a number of water quality issues along Moonee Ponds Creek, including high heavy metal concentrations in sediments and high nutrient levels. In particular, the creek had extremely high levels of cadmium and chromium. The source of these high levels is unknown and requires further investigation. Possible sources contributing to the heavy metal loads include road run-off, the historical uses of the area (such as by D:\687303898.doc Page 21 Moreland Stormwater Management Plan: Vol 1 - The Strategy the electro-plating industry), leaking sewers, and old landfills (for example, Kingsford Smith Ulm Reserve). 5.2.2 Summary of Sources of Water Quality Threats The City of Moreland is an almost fully developed urban area with a small number of known point sources of pollution, mainly from industrial areas. It suffers from many non-point (diffuse) sources of stormwater contamination generated from a range of activities and land uses. The most common stormwater threats in the City of Moreland are associated with the following: Major land subdivision and development activities Building and construction activities Other agency operations Concrete industry Operation of sewerage system Industrial areas Residential areas Major roads Commercial operations Council operations The following two figures map locations in the municipality where stormwater threats have been identified - Figure 5.2 identifies EPA investigation areas associated with pollution events and Figure 5.3 indicates the location of a range of threats in the municipality identified through the SWMP risk assessment process. A comprehensive list of threats is provided in Volume 2. D:\687303898.doc Page 22 Moreland Stormwater Management Plan: Vol 1 - The Strategy Figure 5.2: Stormwater Investigations (EPA) in the City of Moreland D:\687303898.doc Page 23 Moreland Stormwater Management Plan: Vol 1 - The Strategy Figure 5.3: Stormwater Threats in the City of Moreland. D:\687303898.doc Page 24 Moreland Stormwater Management Plan: Vol 1 - The Strategy 5.2.3 Priority Threats Stormwater threats to the values of receiving water environments were prioritised through the risk assessment process outlined in Section 2.3. This process is based on the Urban Stormwater Best Practice Environmental Management Guidelines (Stormwater Committee, 1999). The highest priority threats in the City of Moreland are depicted in Table 5.2. Table 5.4: Summary of Key Threats Activity Impact Location Development Sediment into drains Pentridge (ME3) Riverwalk (MO1) Gowanbrae (MO1) Increase in impervious area and resultant increase in stormwater run-off flows All reaches Building Increase in impervious area and resultant increase in stormwater run-off flows All reaches Operation of Sewerage Systems Illegal connections to stormwater system All reaches Leaking or damaged sewers (nutrients) All reaches Sewer overflow structures (emergency relief structures) All reaches Storage of drums/other materials near drains ME3 Motor vehicle industry repairs ME3 Uncontained on site spills ME3 Residential Invasive weeds All reaches Roads Construction or reconstruction of roads All reaches Resealing works: lack of clean-up, excess material often washed into drainage system All reaches Use of major roads by heavy vehicles All reaches Car parking facilities All reaches Disposal of cigarette butts ME3 Disposal of fast food waste All reaches Disposal of ATM receipts All reaches Existing street trees which are categorised as environmental weeds All reaches Application of fertilisers etc. to major open space areas All reaches Industrial Commercial Council Operations The assessment indicates that the City of Moreland experiences similar problems facing other municipalities in the inner to middle ring suburbs of Melbourne. The opportunity to respond effectively to stormwater pollution is constrained by a developed urban environment where floodplains have historically been alienated for various forms of development, thus limiting opportunities for stormwater treatment wetlands. In addition, as the City of Moreland is a substantially developed municipality, there are only limited opportunities to utilise the planning scheme and planning conditions to regulate development and improve stormwater outcomes. D:\687303898.doc Page 25 Moreland Stormwater Management Plan: Vol 1 - The Strategy Common to many of the threats identified in the risk assessment process is a lack of general awareness of the stormwater system and its management. The operation of the urban stormwater system is largely invisible because most stormwater is collected and transported to waterways by an established underground drainage network. As a result, there is a poor level of understanding of the threats posed to stormwater quality and the impact of those threats on waterway environments. D:\687303898.doc Page 26 Moreland Stormwater Management Plan: Vol 1 - The Strategy 6. Management Strategies As discussed in the previous section, the water quality of the main waterways within the City of Moreland is generally considered to be poor to moderate due to the impacts of a range of urban run-off contaminants. As a result, the emphasis of the SWMP is on recommended actions that address known problems in the expectation that their introduction will mitigate negative impacts on water quality. The SWMP incorporates a number of strategies to address priority stormwater threats in the municipality. These strategies are grouped into two broad categories: Issue Specific Strategies, which target specific land uses and activities; and General Management Strategies, which apply generally to stormwater issues throughout the municipality. Each strategy is supported by an objective and an associated suite of actions designed to achieve the objective. This includes details on responsibilities and estimated costs. Each action is assigned a priority level from the list of priorities contained below in Table 6.1. Table 6.1: Timing for Strategies Rank Priority Timing 1 High Commence implementation immediately, preferably before the end of 2001/2002. 1+ High Commence implementation immediately, preferably before the end of 2001/2002 and then on an ongoing basis. 2 Medium Commence implementation in the short term, preferably before the end of 2002/2003. 2+ Medium Commence implementation in the short term, preferably before the end of 2002/2003 and then on an ongoing basis. 3 Low Commence implementation in the medium term, preferably before the end of 2004/2005. 3+ Low Commence implementation in the medium term, preferably before the end of 2004/2005 and then on an ongoing basis. Indicative costings have been identified for most actions. However, there are circumstances where an action could be part of or combined with another action in the SWMP. These actions have been cross-referenced to avoid the duplication of costs. There are also instances where actions are part of existing programs, strategies and commitments and are funded by other means. They are identified as follows: n1 - Negligible cost and funded through existing operational budget. n2 - Funded under other programs (Litter Strategy, Drainage Strategy etc). n3 - Existing commitment funded from within existing operating budget. D:\687303898.doc Page 27 Moreland Stormwater Management Plan: Vol 1 - The Strategy 6.1 Issue Specific Strategies The SWMP incorporates a number of strategies that specifically target the following land uses and activities: Subdivision and development; Residential areas; Commercial areas; Industrial activities; Sewerage system; Roads and car parks; and Specific structural treatment measures to address particular problems associated with land uses and activities. 6.1.1 Subdivision and Development Context As the City of Moreland is a heavily developed urban municipality there are limited opportunities for new major developments. There is, however, some major new redevelopment in the City and many smaller infill developments associated with former school sites, past industrial land uses and dual occupancy developments. Social and demographic change in the City of Moreland is generating pressure for redevelopment of older established areas. The average size of households (people per dwelling) in the municipality is declining, resulting in more intensive development in order to accommodate a static or marginally increasing population. Increased volumes of stormwater run-off generated by increased impervious areas have also been identified as one of the most significant threats to stormwater quality in the City of Moreland. Infill development and redevelopment can collectively result in considerable construction activity that, if not properly managed, can significantly impact stormwater quality. The risk assessment process has identified the potential for sediments to enter drains from development and redevelopment in the municipality. The former Pentridge Prison site, Riverwalk Estate and Gowanbrea have been identified as particular areas of concern. In addition to sedimentation, other problems can result due to poorly managed building sites, including cement and building litter being released into the stormwater system. Careful planning and management is required to minimise the negative impacts of construction on stormwater quality. Increased awareness of the potential impacts of construction activity, supported by appropriate controls (for example, planning and building controls and local laws), will assist in addressing problems associated with subdivision and development. While management programs should be targeted at larger redevelopment sites, attention should also be directed at minimising the impacts of building and construction related activities on stormwater quality across the whole municipality in order to address the collective impacts of numerous smaller development projects. D:\687303898.doc Page 28 Moreland Stormwater Management Plan: Vol 1 - The Strategy Objective To incorporate stormwater protection measures in the planning, design and construction phases of subdivision and development activity, so as to minimise adverse impacts on the quality of stormwater and receiving water environments in the City of Moreland.

MCC EPA 1+ n3 D9 Facilitate demonstration projects including best practice stormwater management techniques. MCC MW 2+ n1 No. Action D1 6.1.2 Residential Areas Context While established residential areas are not considered to be a significant source of stormwater contamination, the growth of home help and domestic service industries has focussed attention on their potential contribution to stormwater pollution. Domestic service industries include carpet cleaning, roof cleaning, garden maintenance, and car repair and servicing. Some of these activities use chemical cleaning and lubricating agents and many operators are unaware of the impact that discharge of wastes to stormwater can have on receiving water environments. D:\687303898.doc Page 29 Moreland Stormwater Management Plan: Vol 1 - The Strategy In addition, simple everyday activities in residential areas can have cumulative impacts on local waterways. For example, car washing on the streets or paved driveways can generate significant quantities of detergents and associated nutrients for transport to local waterways. Other pollutants identified as threats from the residential sector include dog faeces, weed seeds from domestic gardens, dust from brick cutting, and wastes from paint brush cleaning disposed to the stormwater system instead of the sewer. Lawn clippings, exotic leaf litter and pruning products can also generate large amounts of organic material, with some material having the potential to enter the stormwater system and affect downstream water quality. Organic material (twigs, grass clippings and leaves) makes up the largest proportion (about two-thirds) of gross pollutants carried by stormwater (Allison et. al., 1997). These materials contribute significantly to the biological oxygen demand in receiving waters (Wong, Breen and Lloyd, 2000). At certain times of the year much of the vegetative material entering the stormwater system is from leaf litter contributed by exotic trees. In an older municipality such as the City of Moreland, with street tree plantings of London Planes and other exotic trees, this can cause impacts on the nutrient load transported to receiving waterbodies during autumn. The size of the problem is currently not well defined (see Allison, 1996). In addition, vegetative material also carries weed seed. Of particular concern is the transport of Desert Ash seed, which is a serious weed invading waterway riparian zones. The parks and open spaces (as well as many private properties) in the municipality contain Desert Ash trees of a mature age, each producing large quantities of seed capable of being transported to stream banks. The narrow width of many older streets and laneways in the municipality (such as those founds in parts of Brunswick) can create difficulties for the efficient collection of garbage and recyclables, with consequent impacts on the generation of litter and its carriage into the stormwater drainage network. Objective To raise the awareness of the issues associated with stormwater and its management in order to facilitate positive behavioural changes and an overall decrease in impacts on receiving water environments from the residential sector.

MCC car washing industry 1+ $10k 6.1.3 Commercial Areas Context The major threats to stormwater quality from activities in commercial areas in the City of Moreland arise from issues such as litter, run-off from car parking areas, spillages from private and public rubbish bins and rubbish dumping. In particular, the Sydney Road and Lygon Street commercial areas are key locations where these types of problems occur due to the nature and density of development. Common problems include the failure to regularly empty commercial rubbish skips, inappropriate storage of goods (including cooking oils and wastes) at the rear of commercial premises and display of goods on footpaths where packaging and other materials can find their way into the stormwater system. Furthermore, these areas are heavily trafficked by motor vehicles and pedestrians. Pollution from vehicles, spills from waste collection activities and poor waste management practices by shopkeepers can result in pollutants entering the stormwater system through local drains. Stormwater threats can be minimised through improved community (including residents, shoppers, traders and waste transporters) awareness, supported by the appropriate design and location of litterbins and stricter regulation. While it is important to implement these programs in all commercial areas, they should focus in particular on major commercial areas (such as Lygon Street and Sydney Road), and on those activities identified through the risk assessment process as posing the D:\687303898.doc Page 31 Moreland Stormwater Management Plan: Vol 1 - The Strategy greatest threats, including the disposal of cigarette butts, fast food wrappers and ATM receipts.

MCC & EPA - 2 See ED12 No. Action C1 D:\687303898.doc Page 32 Moreland Stormwater Management Plan: Vol 1 - The Strategy 6.1.4 Industrial Activities Context A number of stormwater threats have been identified in the industrial areas of the City of Moreland, including Trade Place, Newlands Road and the Bakers Road area, all in North Coburg. In particular, poor waste disposal and storage practices can have an adverse impact on stormwater. The major threats are generally associated with discharges from the motor vehicle repair and concrete industries. Spills associated with automotive repair activities (such as those around Bakers Road) result in oil and solvents being washed into the stormwater network. Other important issues include poor disposal of waste products (oils, etc), spillages and illegal dumping. These threats are often found in areas where small groups of small-scale industrial businesses have established and where site management practices are not well implemented. The promotion of improved environmental practices within industrial areas, supported by enforcement activities, will aid in reducing the impacts of industrial related activity on stormwater quality. While such programs should be implemented in all industrial areas, they should target the North Coburg industrial area and focus on priority threats (including storage of drums near drains, discharges from the automotive repair industry and control of spills).

Sewerage System Context The metropolitan sewerage system is designed to quarantine and treat sewage in a safe manner, without adverse impact on the environment. Damaged sewers or illegal connections of stormwater pipes to the sewerage network can result in detrimental releases to the environment and can exacerbate wet weather sewer overflow problems, which ultimately impact on the health of receiving waters. Already the Merri Creek Basin has the highest number of wet weather spills within Melbourne’s sewerage system, primarily from Yarra Valley Water’s system, but also from Melbourne Water’s Merri Creek Main Sewer. The frequency of spills is not compatible with EPA’s objectives articulated in SEPP Schedules F6 and F7 and the Memorandum of Understanding with Melbourne Water. Given this, Melbourne Water is undertaking investigations which may lead to a number of works (including a possible Merri Creek Diversion Sewer) to address this issue. While it is anticipated that any such works would relieve capacity problems and reduce spills from their current levels, it would still be necessary to protect the wet weather capacity of the sewerage system by ensuring that stormwater connections to sewer are eliminated. This issue is typically more common in older residential areas. In addition, there are isolated instances of connection of some household wastewater to the stormwater system. Objective To minimise connections of stormwater to the sewerage system and consequent potential for wet weather overflows to the waterways, and minimise instances of household wastewater discharge to stormwater.

MCC - 1 n1 No. Action S1 S4 6.1.6 MWC MCC MWC Roads and Car Parks Context Roads are a significant source of stormwater pollution. In addition to the local road network, the City of Moreland is traversed or bordered by some of Melbourne’s major road links (including Sydney Road, Bell Street, the Western Ring Road and City Link). The use and management of these transport links has implications for stormwater management. Much of the oil, grease, sediment, litter, tyre rubber and associated wastes that collect on roads are transported into the drainage system and receiving environments, damaging the health of those environments, often with cumulative detrimental effects. In addition, brake-sand used by trams can also be washed into the stormwater system, with consequent impacts on receiving water environments. Council is committed to the continued development of an integrated transportation system (see the Moreland Integrated Transportation Strategy), including achieving a modal shift in transport to decrease negative environmental impacts associated with some forms of transport. Reductions in use of the more intensive modes of D:\687303898.doc Page 35 Moreland Stormwater Management Plan: Vol 1 - The Strategy transport (particularly automobiles) will ease some of the road related pressures on waterways. It is also possible to reduce the incremental, cumulative effects of road vehicle use through the improved design of roads, road verges, median strips and carparks. Lack of available space for treatment measures in road verges, however, is a significant constraint in highly developed areas like the City of Moreland.

A thorough assessment should be undertaken in order to most effectively identify needs and develop a program of well-researched and cost effective works. Structural stormwater treatment methods involve building structures (such as litter traps, porous pavements or wetlands) to reduce run-off volumes or remove pollutants after they have entered the stormwater system. While in some cases structural treatment measures may be the most effective means of protecting stormwater quality, other additional measures such as community education, planning controls and/or changes to operational practices, should still be pursued to address problems at their source. In some cases, although there is evidence of pollutants entering waterways from the drainage system, the source of these pollutants is unknown. Before structural treatments are installed, it is necessary to first identify the source of pollutants to ensure the most effective structural treatment measures are undertaken. The intensely developed nature of the municipality limits the space available for installation of stormwater protection treatments such as wetlands and sediment ponds. Accordingly, it is critical that source control measures are adopted to minimise the discharge of contaminants into the stormwater system. Objective To ensure that receiving water environments are protected from increased stormwater flows and pollutants that have already entered the stormwater system through the use of structural treatment devices. Strategy No. Action W1 Undertake an annual review of the implementation of works recommended in the Litter Trap Action Plan (Allison & Partners 1998).

As a result, there is a need to carefully identify organisational responsibilities, coordinate management responses and capitalise on the expertise that can be shared between organisations. This involves the establishment and continued effective use of communication mechanisms within and between Council and other relevant agencies to facilitate best practice stormwater management. Many of the land use activities and associated stormwater quality issues in the City of Moreland are not confined to the City of Moreland alone, but apply more generally throughout much of the Melbourne metropolitan area. Council will continue to advocate that these issues be addressed through peak bodies and agencies (including EPA, DoI and Melbourne Water) operating at the State and regional levels. Objective To establish a cooperative approach to stormwater management in the City of Moreland between Council, Melbourne Water, EPA, other relevant agencies, adjacent councils, the community and businesses.

PAR4 6.2.2 Respons ibility Planning/Development Assessment Context The planning process can play a leading role in achieving effective stormwater management in relation to new developments requiring approval. This can be achieved through recognition of stormwater as an issue in the Municipal Strategic Statement, the clear articulation of policies in the Local Planning Policy Framework, the application of appropriate zones and overlays and the assessment of development applications. While the Moreland Planning Scheme contains a number of provisions that refer to stormwater related issues, there is currently no overall policy statement relating specifically to stormwater, or for waterways and streams in general. Similarly, Council’s suite of standard planning permit conditions does not include conditions relating to sedimentation, run-off and litter control during the subdivision and construction stages. While planning can play an important role in stormwater protection, it cannot be relied upon as the sole source of regulation. The ability to implement change through the planning system is limited due to the substantially developed nature of the municipality and the fact that many developments occur without the need for planning permits. However, within these basic constraints, changes to the building control system and the development and implementation of appropriate local laws can assist in protecting stormwater from the impacts of construction. It is important D:\687303898.doc Page 40 Moreland Stormwater Management Plan: Vol 1 - The Strategy to note, however, that while Council has the ability to introduce local laws, changes to the building system and the State Planning Framework must be implemented by the State Government. Council officer contacts with builders and renovators provide an important opportunity to raise the awareness of stormwater management issues during the crucial building and construction phase. It is important, therefore, for Council staff to be trained and educated in best practice stormwater management. In addition, there are a number of annual and permanent building industry events and display centres that can be used to educate owner-builders, renovators, and trades people on best practice stormwater management. Objective To establish a framework that recognises and promotes best practice stormwater management through effective statutory and strategic planning, the adoption of coordinated assessment processes, and the establishment and implementation of appropriate permit conditions.

See ENF5 Operations of Council and Other Agencies Context Council and service authorities have responsibility for a range of operations that can have a direct impact on stormwater, including drainage, waste collection, street cleansing, road maintenance and open space management. It is important that these activities are conducted in a manner that minimises their environmental impact and protects stormwater quality. There are a range of methods by which Council can improve its operations in order to avoid or reduce negative environmental impacts. A key opportunity in this regard is through the training of Council’s operations staff, as well as staff in the contracts administration areas (in order to facilitate the identification of water quality related issues as part of the specification development stage). This training can be implemented through Council’s induction program for new employees, as well as through relevant specialised training courses. Council also plays an important leadership role in the area of environmental management. This leadership role involves promoting best practice techniques and practices through a variety of methods, including innovative demonstration projects.

Raising general awareness of key stormwater issues is fundamental to achieving effective stormwater management. It is critical that education initiatives be targeted and include Council staff, local schools, and the wider community. Council is committed to environmental education and has achieved success in this area with a range of initiatives. These initiatives include partnerships with the private sector and close networks with Moreland schools and community groups. For example, Council has supported CERES throughout its development as a regional environmental education centre. CERES has a number of water and stormwater related initiatives established on site, and additional opportunities are currently being explored. Council’s programs on energy and waste education through the highly successful Footprints program provide a model upon which stormwater education in local schools can be based. In addition, Council’s partnership with CitiPower provides another example of a successful environmental educational program. Council has worked with CitiPower over recent years to development the Sustainable Energy House (located at CERES) as a valuable educational asset for the community. It is important that these initiatives be built on and expanded to include stormwater issues.

ED14 6.2.6 Respons ibility Water Quality Initiatives Context The existing data on water quality for metropolitan Melbourne waterways indicates that water quality is adversely affected by stormwater run-off from urban areas. The water quality of the main waterways within the City of Moreland is poor to moderate due to the impacts of a range of urban run-off contaminants. Only by addressing these known water quality problems can improvements be made to stormwater quality. It is important that efforts continue to be directed at improving the knowledge base relating to water pollutants and their sources. This knowledge is critical to the development of appropriate and effective initiatives to improve water quality. There is scope for increasing the level of water quality monitoring undertaken in the City of Moreland to assess progress made in water quality improvements (through, for example, expanding the WaterWatch program). Objective To address identified water quality issues with specifically targeted actions and resources, and to increase the knowledge base of the pollution sources impacting on stormwater and water quality.

While Council has responsibilities for the provision and management of services across a range of functional areas, it is only one of a number of agencies having a role in stormwater management. Accordingly, implementation of the SWMP will require a partnership approach between Council, Melbourne Water, EPA, other agencies, adjacent councils, businesses and the wider community to ensure that stormwater quality is improved and protected. It is important that organisations nominated in the SWMP as having the lead role in implementing an action be assisted by those organisations that are nominated in a support role. To ensure that the SWMP strategies remain current and targeted, actions should be audited annually, with a comprehensive review completed after three years,. D:\687303898.doc Page 48 Moreland Stormwater Management Plan: Vol 1 - The Strategy Objective To implement the SWMP in a cooperative manner and ensure that the SWMP remains responsive to stormwater management issues as they change over time.

Conclusion By commissioning and adopting the SWMP, Council has strengthened its commitment to improving and protecting local waterways and surrounding environs. The SWMP provides a detailed strategy for effective stormwater management throughout the City of Moreland, thereby complementing and building upon Council’s existing environmental strategies and programs. The challenge is for all stakeholders, including the general together to implement the recommendations of the SWMP to and enhancement of the important environmental, economic, and hydraulic values of Merri Creek, Moonee Ponds Creek tributaries. 7.1 community, to work aid in the protection recreational, cultural and their respective Measuring Success Ultimately the success of the SWMP can be gauged by changes to water quality in local waterways. In assessing these future changes the impacts of upstream and adjacent councils must also be accounted for. The actions recommended in the SWMP cover an array of issues and a range of Council functions and stakeholders, including responsible agencies, community and industry groups, and the wider community. The success of the SWMP can therefore be demonstrated by a diverse range of outcomes, including: Improved Management and Internal Coordination, as evidenced by regular meetings of the Moreland Stormwater Quality Committee and the development of implementation plans by those Council departments with accountabilities for the SWMP’s actions. Improved Urban Design, as evidenced by the increased use of water sensitive urban design in new development projects. Improved Development & Construction Practice, as evidenced by better site environmental management and a reduction in the volumes of soil, litter, particulates, and other wastes from construction sites entering the stormwater system. Ongoing Improvements in Community Awareness, as evidenced by reduced littering and an increase in on-site detention and the re-use of stormwater. Improved Commercial and Industrial Practice, as evidenced by reductions in dumping, overflow of garbage bins and the accidental or deliberate discharge of wastes and contaminated run-off to stormwater. Improved Stormwater Quality discharged from the City of Moreland into the Merri and Moonee Ponds Creeks and their respective tributaries. The above provides a strong set of parameters through which the success of the SWMP can be assessed. Council, in conjunction with the community, can take these further by developing a set of key performance criteria against which the implementation of the SWMP can be measured. D:\687303898.doc Page 50 Moreland Stormwater Management Plan: Vol 1 - The Strategy 7.2 Monitoring and Review The SWMP provides a framework for achieving improved stormwater management and details specific actions for implementation. While priority actions are identified in the SWMP, it is envisaged that priorities will change over time due to changing circumstances. Accordingly, Council and other stakeholders will regularly update priority actions on an annual basis in accordance with budget planning activities, with a comprehensive review of the SWMP undertaken in three years. 7.3 Funding The implementation of the SWMP will require a substantial commitment in funding by Council and other stakeholders. While the SWMP provides estimated costs to implement the various actions, these will need to be considered in the context of broader responsibilities and the ability of Council and others to access funds. A summary of all actions recommended in the SWMP and their associated estimated costs is presented in Table 7.1. In total, the allocation for implementation of these actions over the 2001/02 – 2004/05 financial years is estimated as follows: FY2001/02 $322,000 FY2002/03 $406,000 FY2004/05 $191,000 Various funding sources are available, most notably the State Government’s allocation of $22.5 million over the next three years for urban stormwater projects. Many actions recommended in the SWMP qualify for funding under this program and it should be investigated as a source to support SWMP implementation. Other sources of funding are available and should also be pursued, particularly where joint funding opportunities exist under various programs (such as Pride of Place Funding, Recreation Grants, and Infrastructure and Environmental Improvement Grants through EPA, EcoRecycle, the DoI and other agencies).
