Monitoring                   n   Monitoring recommended in the Stormwater Management Plan / Sediment and Erosion Control Plan (Appendix A), including:
                                         Monthly water quality monitoring of rainwater tanks associated with each beach shack (microbial, nuisance organisms, pH, toxic
                                         chemicals, surface films);
                                         Monthly water quality monitoring of underground rainwater tanks (microbial, nuisance organisms, aesthetics, clarity and colour, toxic
                                         chemicals and debris);
                                         Monthly inspections of garden surfaces and vegetated buffers for bare patches;
                                         Monthly inspections of the bioretention trenches for disturbances to trench floor, and the accumulated debris, litter and silt drapes;
                                         Monthly inspections of the high flow outlet weir grate in bioretention trenches for blockages or detritus build-up;
                                         Monthly inspections of the bioretention trenches for vegetation cover and weeds;
                             Maintaining pipe infrastructure
                                         Inspect flows entering and exiting pipe-work during flow events;
                                         Daily inspection for evidence of leaking pipe-work;
                             Maintaining the constructed wetland system
                                         Monthly inspections of the wetland system for accumulated debris and litter and weeds;
                                         Monthly water quality monitoring (total suspended solids, total phosphorus, total nitrogen, pH);
                                          Twice yearly soil pH testing of gardens and vegetated buffers;
Reporting / Responsibility   Reporting
