Manly Lagoon Dredging Project – Review of Environmental FactorsPrepared for Manly and Warringah CouncilsLimit works to recommended standard hours i.e. during the day;Schedule noise and vibration generating works during less sensitive time periodswhere possible i.e. around times of high background noise;Use quieter work methods and equipment where possible, such as alternative lowernoise and vibration-generating plant and equipment, and ensure equipment hasquality mufflers installed;Maintain all equipment used on site;Noise shields and barriers for residences immediately adjacent to works;Consult with affected residents prior to commencement of works;Establish a register for noise and vibration complaints;If necessary, provide respite periods for affected residences; andConsult with affected schools to ensure noise and vibration-generating works are notscheduled to occur during examination periods.All feasible and reasonable measures should be undertaken to minimise construction noiseand vibration where possible. Manly and Warringah Councils should communicate withaffected residents, and Mackellar Girls High School, in the vicinity of the Lagoon prior tocommencement of works to clearly explain the duration, noise and vibration levels of theworks, and any respite periods that will be provided, as part of the Management Plan. Inparticular, dredging in the vicinity of the school during exam times should be avoided.Recommended standard hours for construction work, as reported by DECC (2009c), are: Monday to Friday 7am to 6pm; Saturday 8am to 1pm; and Sundays or Public Holidays No work.The complaints register should be made accessible to DECCW and the local community onrequest. All complaints should be documented and investigated. Manly and WarringahCouncils should ensure that there are systems in place to respond to and resolve any issuesraised. Further monitoring and mitigation measures may be required following theinvestigation of a complaint.Prior to the commencement of works, a complaints telephone line dedicated to taking callsfrom the public will be established. This will be advertised to local residents and by the useof site signage. These provisions will be advertised to the public via means of theCommunity Consultation Plan, which will be prepared by Manly and Warringah Councils.In addition, regular, subjective monitoring of noise will be undertaken by the sitesuperintendent or an independent external person. This will consist of daily checks at threelocal receptor locations, with the results of all observations being maintained in a log. Wherehigh levels are observed, or complaints are received, quantitative monitoring should beintroduced.2 July 2010 Cardno (NSW/ACT) Pty Ltd 104H:\Doc\2010\Reports.2010\Rep2580v4.doc
