The following actions should be taken when constructing roads. • Prior to preparation of plans for road construction or widening, investigate the relevant permit requirements (e.g. is work occurring near a waterbody). • Carry out site inspections with all interested parties prior to the preparation of road construction or widening plans on roads of high and medium conservation value. This will ensure that the most appropriate methods to minimise vegetation loss will be included and will assist to plan the rehabilitation of the site after works are completed. • Conduct an assessment to determine impacts on environmental and other values (REF or EIS) prior to road construction or widening works being carried out. The environmental assessment should involve Council staff from design, planning and works walking the entire route to identify significant roadside vegetation and other environmental considerations. The process should, among other things, identify: o all construction activities and where they will take place, including stockpiles and dump sites, site sheds, machinery storage and turn around points, vehicle parking sites, access roads; o sites of environmental or cultural significance that are not to be disturbed; and o the location and type of erosion and sediment control measures. • Consider modifying the design to reduce vegetation loss (e.g. different alignments, pavement and shoulder widths, use of kerb and channel); • Plan the construction phase to occur at the optimum time of year to minimise impacts (e.g. erosion). To minimise erosion, undertake (where appropriate) construction works in stages so as to expose the smallest work area for the shortest time; • Prior to commencement of works: o identify all boundaries and use fencing, barricades or other markers to delineate these; o inform all workers and contractors of permit conditions; and o train workers and contractors in erosion control, vegetation removal and vegetation protection measures prior to commencement of works. • Apply general principles during road construction that will assist in protecting roadside vegetation: o Stay within limits of construction (disturbance) zones; o avoid using or storing heavy machinery on all native roadside vegetation where possible; o keep construction machinery out of high and medium priority roadside vegetation sites; o keep machinery, equipment or material on designated storage places clear of native trees, shrubs and grasses, and use designated turning circles. Use of areas supporting native vegetation by machinery, equipment or material can damage the groundcover vegetation and cause soil compaction, which damages tree roots; © E C O L O G I C AL AU S T R AL I A P T Y L T D 48
