Willoughby City As part of the Get the Site Right Campaign Council will be conducting a one-day inspection blitz of building sites across our area on 20 May to check pollution is being disposed of properly. Builders and home renovators are being urged to stop run-off from their building sites polluting waterways and green spaces that Sydneysiders increasingly rely on for recreation and enjoyment. Willoughby City is home to the Middle Harbour estuary and Lane Cover River, important tributaries to the spectacular Sydney Harbour. If sediment runoff from building sites gets into our local waterways, it not only affects water quality but harms marine plants and animals.
