TEC Threatened Ecological Communities TSC Act Threatened Species Conservation Act 1995 PAGE v Mount Victoria Village Safety Upgrade REF Technical Paper – Biodiversity Assessment Executive summary Background Roads and Maritime proposes to construct safety works along the Great Western Highway at Mount Victoria, approximately 15 kilometres southeast of Lithgow and approximately five kilometres northwest of Blackheath. The proposed works extend from Browntown Oval, to the east of the village and continues just west of Mount York Road with approximately 2.3 kilometres of safety enhancements. The main features of the proposal include: • Widening the highway shoulders by up to about three metres on each side of the road. • Moving the highway about 20 metres to the north east between Mount Piddington Road and Hooper Street to improve the road alignment. • Upgrading six intersections, including: – Dedicated right turn bays at Harley Avenue, Mount Piddington Road, Kanimbla Valley Road and Selsdon Street. – Dedicated left turn bay at Mount York Road with the use of line marking. – Basic right turn at Victoria Falls Road. – Left in /left out only at Hooper Street and Cecil Road with the use of appropriate sign posting and line marking. • Providing a new service road to improve and provide safe access to private properties on the southern side of the highway between Cecil Road and Mount Piddington Road. • Providing a pedestrian refuge in the central median near Selsdon Street and improved connectivity through additional pedestrian pathways within the proposal area. • Building four retaining walls up to 5.5 metres high and up to 230 metres long. • Building two new culverts and upgrading existing drainage infrastructure. • Providing water quality basins at potentially three locations. • Temporary construction facilities, including construction compounds and stockpile sites along its length. • Tie-ins with the existing pavement and highway levels at the end of each section. This report details the methods and results of a biodiversity assessment prepared to identify the extent and potential magnitude of ecological impacts associated with the proposal. The report addresses the requirements for assessment of significance under the NSW Environmental Planning and Assessment Act 1979 (EP&A Act) and the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). Existing environment The study area is located within the South Eastern Highlands and Sydney Basin bioregions (Interim Biogeographic Regionalisation for Australia, 2012). The study area is located entirely within the Hawkesbury-Nepean Catchment Management Area (CMA) and traverses the Mid Coxs River and Gorse River Subcatchments. The region is important for biodiversity because it provides a variety of landforms, aspects and microhabitats that support a high diversity of plants and animals.
