PLANNING & ENVIRONMENT COMMITTEE MEETING AGENDA                                       11 JULY 2017

       e  Joy, C (Water Studies P/L, 1996) Impact of Land Use on the Quality of Surface Runoff
          Quality in the Lake MacDonald Catchment, A Planning Scheme Review Project, Noosa
          Council.

       This document does not appear to be available online and as such, it was not available for
       review. Despite this, numerous studies on the typical values associated with urban runoff
       have been completed, most notably the following work, the results of which are utilised to
       calibrate MUSIC:
       e  Fletcher, T., Duncan,H., Poelsma, P. & Lloyd, S. (2004). Stormwater flow and quality,
          and the effectiveness of non-proprietary stormwater treatment measures — a review and
          gap analysis.
       The seminal work by Fletcher et al. (2004) noted that undeveloped catchments in Southeast
       Queensland have concentrations typical to that of Figure 1. It should be noted that the
       median Event Mean Concentrations (EMC) for natural bush area, as a surrogate for an
       undeveloped catchment) substantially exceed the nominated targets associated with the
       POD. It should be noted that the values in Figure 1 are derived from numerous sites and in
       some cases, were established based upon a smaller dataset.
                           Table 2.35 EMC and DWC Estimates for South-East Queensland for use in EMSS.
