Code Assessment - 12 Eenie Creek Rd (RESOLVED DRAFT)

11        NOOSA PLAN 2020, SECTION 9.4.8



          Water Quality and Drainage Code
Applies because: Works code named as a benchmark in Table 5.5.10.
The proposal is an internal fit-out of an existing building together with a new frontage treatment on a
developed, fully serviced and generally flat site. The outcomes of this code are addressed on that basis.
