The primary objective of this study was to identify the overland flow paths within the entire Liverpool LGA, a total area of some 317 km2. In this context, overland flooding is considered separate from mainstream flooding within the LGA which has been investigated in most of the major catchments in the LGA including the Georges River, Cabramatta Creek, Anzac Creek, Kemps Creek, South Creek, Badgerys Creek and the Nepean River. The Stage 1 study represents the first significant attempt to map major overland flow paths within the LGA and quantify associated flood risk to property. By defining the major flood behaviour for overland flooding across the LGA, sub-catchments were ranked in terms of flood risk and prioritised for further detailed assessment. The Liverpool Overland Flow Path Study Stage 2 (BMT WBM, 2008) and Stage 3 (BMT WBM, 2010) investigated in further detail the flooding associated with the highest priority sub-catchments identified in the initial Stage 1 scoping study. Following the Stage 1, 2 and 3 studies, it was determined that a broad scale overland flooding investigation was required within the urban catchment area with the purpose of re-prioritising affected catchments for future detailed studies. This is the objective of the current study, representing Stage 4 of the Liverpool Overland Flow Path Study. The study has been commissioned by Liverpool City Council with funding assistance and technical support from the NSW Office of Environment and Heritage (OEH). #Model Development The primary objective of the Stage 4 Study is to identify major overland flow paths within the urban areas of Liverpool LGA. This characterisation of the existing flood behaviour in the urban environments is achieved through the development of detailed hydrologic and hydraulic models, as was completed for the Stage 2 and Stage 3 studies. A detailed two-dimensional (2D) hydraulic model of the study area was developed using the TUFLOW software. The models have developed to simulate overland flow paths only without the representation of the local underground stormwater drainage system. In the context of the overland flow path study, high resolution topography is necessary to suitably represent available flow paths and water levels, such that infrastructure like roadway/gutters that are expected to convey significant urban drainage. The model has been developed using 2m resolution Digital Elevation models (DEMs) derived from the NSW Land & Property Information (NSW LPI) LiDAR dataset acquired in 2013. The model includes a detailed representation of the land use distribution within the catchment. This distribution considers the different surface roughness types which affect the response to rainfall and movement of overland flow through the catchments. These areas are delineated by the use of aerial photography and cadastral data to identify different land uses, such as vegetated floodplains, paved areas, roads, and urban properties. No detailed calibration of the model was undertaken for specific flood events experienced previously in the catchments. However, the modelled overland flow paths have been compared with the outputs of the detailed Stage2 and Stage 3 modelling which included full stormwater drainage network modelling. The comparisons with the previous detailed modelling outputs confirmed the Stage 4 overland flow path modelling provided a good representation of flow behaviour. Accordingly, the model is considered suitable to identify the remaining key overland flood risk areas within the study area. #Flooding Behaviour The simulation of existing design event conditions is required to determine the nature and extent of the existing flood problem. The modelling incorporated a range of storm durations in order to identify the critical durations across the catchment producing the highest overland flow response. The simulated durations included 15 minutes, 30 minutes, 45 minutes, 1 hour, 90 minutes, 2 hours, 3 hours, 4.5 hours, 6 hours, and 9 hours. The key study output is the mapping of the peak 1% AEP design flood conditions across the study area. The peak design flood depth and inundation extents are mapped over detailed aerial imagery to identify the location of key overland flow paths. Areas of significant existing development affected by overland flooding have been identified as key “hot-spot” areas. A key objective of the Study is the identification of these hot-spot areas for further detailed assessment as required. A number of recent development areas were identified that have been constructed subsequent to the LiDAR data acquisition. Through the development of these new urban areas, overland flow paths have been considerably modified. Details of post-development topography have not been available in a suitable electronic format for inclusion in the models. Accordingly, the modelled overland flow behaviour using the LiDAR data is now superseded in these areas. Key hot-spot areas were initially investigated in detail in the Stage 2 and Stage 3 studies. The Stage 4 study has identified only limited additional development with any significant overland flooding risk. It is considered in many of these areas, the overland flood risk would be further reduced when the performance of existing drainage infrastructure is taken into consideration. Nevertheless, the overland flow path mapping is indicative of a 100% blocked condition for the local sub-surface stormwater drainage network and accordingly identifies development areas susceptible to flooding from system blockages.

A map of the high ecological value waterways and water dependent ecosystems for the Liverpool LGA was prepared by the Science Division of the Department of Planning, Industry and Environment, with input layers and support for the map provided by the former NSW Department of Primary Industries-Fisheries and Department of Industry-Crown Lands and Water. The basis for the map arises from Science Division inputs to strategic planning processes. For example, the map has been included in the Land Use and Infrastructure Implementation Plans for the Wilton (Wilton2040, page 22) and Greater Macarthur (interim plan, page 36) Priority Growth Areas. This map was specifically developed for input to Local Government Local Strategic Planning Statements to support Council’s delivery of Strategy 25.1 of the Greater Sydney Region Plan. The map shows areas where waterways and water dependent ecosystems are defined as high ecological value, based on definitions, guidelines and policies under the Environment Protection and Biodiversity Conservation Act 1999, Biodiversity Conservation Act 2016, Fisheries Management Act 1994 and Water Management Act 2000. Water dependent ecosystems are defined as wetlands, and flora and fauna that rely on water sources (including groundwater). The map represents an overlay of 39 indicators being used by the State Government to define high value, however, not all 39 indicators will be present in any one LGA (see Attachment 1 below). For example, there are 24 indicators making up the map for the Liverpool LGA. It should also be noted that the individual indicators have not been ground-truthed and it is recommended that field assessments and/or a comparison to local mapping be undertaken prior to any decisions being made. The map was created by initially placing a 1 ha (to correspond with a lot size) hexagon grid over the LGA, and attributing the grid with the area, length and/or frequency of occurrence of high value water dependent ecosystems. The purpose of the map is to identify strategic planning priorities for protecting and improving the health of high value waterways and water dependent ecosystems in the LGA. Once identified, the priorities can be used as a basis for identifying aquatic biodiversity refugia, stream rehabilitation efforts and setting management targets and/or land use planning controls that would protect or improve the health of waterways and water dependent ecosystems so they provide the essential services and functions expected of a cool blue-green corridor.

Bewsher Consulting Pty Ltd was originally commissioned by Liverpool City Council, in\r conjunction with Fairfield City Council and the Department of Land and Water\r Conservation (now the Department of Infrastructure, Planning and Natural Resources),\r to undertake a floodplain management study for Cabramatta Creek.\r \r A number of working papers were prepared during the course of the study and a draft\r main report issued in May 1999 [Bewsher Consulting, 1999].\r \r The draft report was not finalised at the time, largely due to uncertainties associated\r with a major highway proposal (referred to as the WSO project in this report) that\r bisects the Cabramatta Creek catchment. The proposed highway and associated\r compensatory flood mitigation works has a significant impact on Liverpool Council’s\r detention basin strategy – in particular, whether or not an earlier proposal to construct a\r large multi-purpose basin in the middle of the catchment, known as Basin 22, would\r be feasible.\r \r By late 2002 many of the uncertainties regarding the proposed WSO and Basin 22 had\r been resolved. Subsequently, Liverpool and Fairfield Councils requested that the draft\r Cabramatta Floodplain Management Study be updated.\r \r This floodplain management study and plan is based on the previous draft report\r submitted in May 1999, updated where appropriate to account for changes that have\r occurred since this time.\r \r Bewsher Consulting has been assisted by Don Fox Planning (town planning advice), the\r University of NSW Water Research Laboratory (hydraulic modelling), Nelson Consulting\r (environmental matters) and Southern Aerial Surveys (aerial mapping).\r \r The study was overseen by both Liverpool Council’s floodplain management committee\r and Fairfield Council’s floodplain management committee. These committees consisted\r of Councillors and staff from both Councils, community representatives, and officers\r from other organisations, such as the Department of Land and Water Conservation\r (now DIPNR), State Emergency Services and the Department of Urban Affairs and\r Planning.\r \r

Principal Outcomes\r

The outcomes of this study include:\r \r - a comprehensive set of aerial photography and detailed contour mapping of the\r catchment;\r - revised flood information in the form of maps showing flood contours and flood\r extents for a range of flood events, in digital format for incorporation into both\r Councils’ GIS computer systems and as hard copy plans;\r - a comprehensive assessment of floodplain management measures, including a\r review of planning controls, flood mitigation works and other measures to reduce\r potential flood problems within the catchment;\r - a range of working papers on specific issues investigated throughout the study,\r which have been progressively presented to the floodplain management\r committees;\r - the Main Report (this document) which summarises the working papers that have\r been undertaken, and presents an overall outline of the floodplain management\r study and the recommended floodplain management plan; and\r - an Executive Summary which provides a concise summary of the study and\r recommended floodplain management plan.\r

Flood Behaviour\r

Flood behaviour has been analysed using the RAFTS hydrologic model to simulate\r flows throughout the creek systems, and the RMA-2V two dimensional hydraulic model\r to simulate the extent and depth of flooding within the catchment. Both models were\r calibrated to floods that were recorded in August 1986 and April 1988. These models\r provide the necessary tools to assess the impact of catchment development,\r compensatory flood mitigation works, and other potential flood mitigation works to\r alleviate existing flooding problems.\r \r The floodplain has been divided into three flood risk precincts (high, medium and low)\r as part of the updated study. Different development controls are also proposed for the\r catchment depending on the type of development and the flood risk precinct that the\r development is located. These controls are included in a planning matrix to be attached\r to Flood Risk Management Development Control Plans that have been proposed for\r both Liverpool and Fairfield Councils.\r \r A flood damages database of potentially flood affected properties has been prepared as\r part of the study. The database provides details of those properties likely to be\r inundated in different sized floods and allows the quantification of potential flood\r damages. Key results from the database indicate that:\r \r - 2,838 residential homes and 218 commercial/industrial buildings would be flooded\r above floor level in the PMF;\r - In the Liverpool LGA, 74 homes and 80 commercial/industrial buildings would be\r flooded above floor level in the 100 year flood;\r - In the Fairfield LGA, 50 homes and 24 commercial/industrial buildings would be\r flooded above floor level in the 100 year flood;\r - The predicted flood damage in the 100 year flood is $16M for Liverpool, and $4.8M\r for Fairfield.\r

Community Consultation\r

Community consultation has also been a major component of the study. This has\r included liaison with community groups and authorities, regular presentations to both\r Councils’ floodplain management committees, two community newsletters and\r questionnaires, two public meetings, and the intended public exhibition of the draft\r Main Report and Executive Summary.\r \r \r

The Floodplain Management Plan\r

A recommended floodplain management plan showing preferred floodplain\r management measures for Cabramatta Creek is presented in Table 11.1 and also\r shown on Figure 11.1. The preferred measures have been determined from a range of\r available measures, after an assessment of the impacts on flooding, as well as\r environmental, social, and economic considerations.\r Recommended options that modify flood behaviour include:\r \r - a revised detention basin strategy for Liverpool City Council;\r - three other detention basins to provide compensatory flood storage for the proposed\r WSO highway;\r - a further detention basin on Brickmakers Creek at Amalfi Park and/or channel\r improvement measures downstream of Amalfi Park;\r - channel works, culvert amplification, and creek rehabilitation works in Brickmakers\r Creek, between Homepride Avenue and Elizabeth Drive;\r - improved flood access along major arterial roads;\r - a package of works in the Elizabeth Drive/Tresalam Street area; and\r - the preparation of bushland management plans and the clearing of rubbish and\r debris from the creek waterways.\r \r Recommended options that modify property include:\r \r - voluntary house raising;\r - flood proofing individual buildings; and\r - controls on new development through a planning matrix approach, which provides\r guidance on appropriate land uses and other development controls.\r \r Recommended options that modify people’s response to flooding include:\r \r - a flood awareness program;\r - improved flood warning system and emergency response management; and\r - the preparation of flood action plans.\r

Timing and Funding\r

Timing of the proposed works will depend on each Council’s overall budgetary\r commitments, and the availability of funds from other sources. Funding will be\r available through a number of sources, as identified in Table 11.1. Components of the\r Plan will be able to be carried out directly by either Liverpool Council or Fairfield\r Council, whilst other components that affect both Council areas will need to be carried\r out jointly.
