    Description

    Liverpool City Council has device counters deployed throughout the city centre to understand how the city is used. Data in this dashboard is derived from Meshed nCounters and CCTV retrofitted with an algorithm developed by University of Wollongong. The algorithm has used machine learning to identify objects in the camera viewfinder and categorise them into pedestrian, vehicle or bicycle. This transforms the CCTV into visual sensors. The nCounters generate data by counting the number of Wi-Fi signals emitted by non-identifiable mobile devices within a specified proximity and performing certain filtering and processing. No individuals are identified by either method. Both methods have advantages and limitations.Advantages of the nCounter method:Can provide insightful data on crowd sizes and individualsAn individual with one device will be counted onceThe nCounter can report the average ‘dwell time’ of the deviceLimitations of the nCounter method:individuals without devices will not be counted (for example young children or people without smart phones),if someone is carrying a smart phone which is in aeroplane mode or switched off then it will not be counted, andindividuals with multiple devices will be counted by the number of devices they have. For example, one person may have two smart phones, therefore the individual will be counted more than once.The visual sensors (CCTV) count the number of bicycles, people and vehicles in the location.Advantages of the visual sensor method:Can provide insightful data on pedestrian, vehicle and bicycle numbers,Re-uses existing common technology on city streets without further visual clutter,Does not rely on individuals carrying their own devices, so useful in areas with lower technology uptakeLimitations of visual sensor method:Individuals can be counted multiple times as they exit and re-enter the camera viewfinder,The machine learning cannot differentiate between bicycles and motorbikesData collected in this dataset can be visualised in the Liverpool City Centre activity dashboard

    Description

    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.

In broad terms, the current study has investigated what can be done to minimise the effects of flooding in the South Creek study area and recommended a strategy in the form of a recommended Floodplain Risk Management Plan. This study and plan constitute key components of the NSW Government’s floodplain risk management process as outlined in the Floodplain Management Manual. #STUDY AREA Liverpool City Council has commissioned Bewsher Consulting Pty Ltd, in association with Don Fox Planning Pty Ltd, to undertake this study and Plan for those portions of the South Creek and Thompson Creek floodplains that lie within the Liverpool LGA. The study area of this Floodplain Risk Management Study covers only a small portion of the total South Creek catchment. The South Creek catchment is a significant tributary of the Hawkesbury–Nepean River and is located about 40km to the west of the Sydney Central Business District. South Creek flows generally from south to north through the study area. The northern boundary of the study area is Elizabeth Drive, while the southern boundary is Bringelly Road and The Northern Road, approximately 7km to the south. The western boundary of the study area is South Creek’s catchment boundary with Badgerys Creek, while the eastern boundary is the catchment boundary with Kemps Creek. #DESIGN FLOWS AND FLOOD LEVELS A RAFTS model was originally established and calibrated for the entire South Creek catchment as part of the 1990 Flood Study for South Creek (Department of Water Resources, 1990) and used in the 1991 FPM Study. These results were used in the analysis of flood mitigation options for the Overett Avenue and Victor Avenue areas and have been adopted for use in the current study. A MIKE-11 model, together with a series of HEC-2 models, were originally established and calibrated for the major creeks within the South Creek catchment as part of the 1990 Flood Study. These models were then used in the 1991 FPM Study. To examine flood mitigation options for the Overett and Victor Avenue areas in more detail, a more detailed MIKE-11 submodel with additional cross-sections was established from the main South Creek model in the mid-1990s. Modelling in the study area over the years has now evolved into the ‘2003 MIKE-11’ model (established as part of this study) that covers all of the study area and includes all the flood mitigation works completed in the study area. This ‘2003 MIKE-11’ model for the South Creek and Thompsons Creek floodplains is now the best representation available for the current flood behaviour in the study area.

The primary objective of this study was to identify the overland flow paths within the entire Liverpool Local Government Area (LGA), a total area of some 317 square kilometres. 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. This preliminary options report identifies the areas of the Liverpool study catchments most susceptible to overland flooding, and identifies potential mitigation options to alleviate or reduce the flood risk: Section 1 introduces the study. Section 2 provides background information to the study. Section 3 outlines the community consultation program undertaken. Section 4 details the modelling approach and presents design flood results. Section 5 provides a summary of the flood damages assessment. Section 6 provides a review of potential floodplain management options. Section 7 details the assessment of structural options to assess “hot-spot” areas.

    Study Area\r

    Liverpool City Council (Council) has recently undertaken the Liverpool Overland Flow Study Stage 1\r (2006) which investigated overland flood risk across the entire Liverpool LGA. The study identified\r and mapped sub-catchments and overland flow paths and prioritised them in terms of flood hazard\r for future detailed study.\r \r Stage 2 of the Overland Flow Path Study, the current study, is focused on the detailed investigation\r of flooding in three of the highest priority areas identified in Stage 1. The study has been\r commissioned by Liverpool City Council with funding assistance from the NSW Department of\r Environment and Climate Change (DECC).\r The three study areas are shown in Figure 1.1 and comprise:\r \r * Area 1 - covering part or all of the suburbs of Heckenberg, Mount Pritchard, Ashcroft, Sadleir, Busby, Miller, Hinchinbrook and Green Valley;\r * Area 2 - covering part or all of the suburbs of Prestons, Lurnea and Cartwright; and\r * Area 3 - covering part or all of the suburbs of Prestons and Horningsea Park.\r \r Area 1 is situated partly within the Cabramatta Creek catchment and partly within the Green Valley\r Creek catchment. Area 2 is situated within the Maxwells Creek catchment (itself a tributary of\r Cabramatta Creek). Area 3 is situated in the Cabramatta Creek catchment also. Detailed locality\r plans for each study area are provided in Sections 5 to 7.\r

    Study Objectives\r

    The objectives of the study are to characterise existing flooding behaviour in the catchment, identify\r significant overland flow paths and flooding locations, and to propose mitigation options to reduce\r existing flood risk.\r Specifically the study aims to:\r \r * Define overland flow behaviour within the study area including flow rates, velocities, water depths\r and extent for the 5% AEP, 1% AEP and PMF events;\r * Produce high quality mapping describing the catchment flooding;\r * Quantify probable flood damages on the basis of expected flood inundation patterns; and\r * Identify potential flood mitigation options that could be implemented to reduce the flood risk.\r \r The primary objective of the study is to examine and define the overland flooding behaviour in the\r study area. This has involved the development of computer models to simulate design flood\r conditions. The results of the modelling have enabled a preliminary assessment of flood risk and\r potential damages and the identification of potential mitigation options. It is expected that these risks\r and mitigation options would be explored in further detail in floodplain management investigations\r subsequent to this flood study.

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.

    Description

    Smart Cities, Smart Liverpool, Smart Pedestrian Project Thousands of people walk through the Liverpool city centre every day and, through the Smart Pedestrian Project, the paths they take will help shape the city’s future. Liverpool City Council is counting pedestrian and vehicle movements around the city centre, collecting data from smart devices and camera-counting technology. The data is stripped of any identification and relayed and collected for analysis by researchers from the University of Wollongong. Liverpool City Council now uses this data to inform planning decisions and respond to the rising number of residents and workers making their way around the city centre every day. Liverpool City Council secured an Australian Government Smart Cities and Suburbs grant to jointly fund the project. Liverpool City Council worked with IT Integration Company Meshed and the University of Wollongong to deliver the technology. Meshed supplied the Low Power Wide Area Network and developed a Wi-Fi smart device counter. The university developed the people and vehicle-counting technology and data analysis. The technology makes use of the city’s existing CCTV cameras to capture images. No images are transmitted over the network, so there is no risk to privacy. This dataset lists the API endpoint URLs to retrieve data for the smart pedestrian project. A dashboard to view the data can be found at https://pavo.its.uow.edu.au/ Please read the API documentation as you need to provide the parameters to make any API calls. An example has been provided below that lists all the visual sensors. The API is divided in two sections: sensors, and readings (data gathered by sensors). Unless otherwise noted: * all datetimes are ISO formatted * all responses are JSON-formatted

Description

Liverpool City Council has device counters deployed throughout the city centre to understand how the city is used. Data in this dashboard is derived from Meshed nCounters and CCTV retrofitted with an algorithm developed by University of Wollongong. The algorithm has used machine learning to identify objects in the camera viewfinder and categorise them into pedestrian, vehicle or bicycle. This transforms the CCTV into visual sensors. The nCounters generate data by counting the number of Wi-Fi signals emitted by non-identifiable mobile devices within a specified proximity and performing certain filtering and processing. No individuals are identified by either method. Both methods have advantages and limitations.Advantages of the nCounter method:Can provide insightful data on crowd sizes and individualsAn individual with one device will be counted onceThe nCounter can report the average ‘dwell time’ of the deviceLimitations of the nCounter method:individuals without devices will not be counted (for example young children or people without smart phones),if someone is carrying a smart phone which is in aeroplane mode or switched off then it will not be counted, andindividuals with multiple devices will be counted by the number of devices they have. For example, one person may have two smart phones, therefore the individual will be counted more than once.The visual sensors (CCTV) count the number of bicycles, people and vehicles in the location.Advantages of the visual sensor method:Can provide insightful data on pedestrian, vehicle and bicycle numbers,Re-uses existing common technology on city streets without further visual clutter,Does not rely on individuals carrying their own devices, so useful in areas with lower technology uptakeLimitations of visual sensor method:Individuals can be counted multiple times as they exit and re-enter the camera viewfinder,The machine learning cannot differentiate between bicycles and motorbikesData collected in this dataset can be visualised in the Liverpool City Centre activity dashboard
