2.2 Previous Land-use, Topography and Drainage

The site is currently vacant land and was previously used as a temporary depot for the machinery
used for the upgrade of the Bruce Highway. The site predominantly drains from north to south, with
an approximate slope of 4%.

2.3 Proposed Land-use

The overall site area is approximately 8243m2, with the area of the proposed new development
utilising the entirety of the site. The proposed development for a highway service centre includes
the service station bowsers, fast food outlet, service station, children’s play area, services, truck
parking and associated carparking and landscaped areas.

A Site Plan is located in Appendix A for further detail.

3.0 WATER QUALITY AND TREATMENT OBJECTIVES
This SMP will demonstrate how the proposed stormwater management strategy complies with the
requirements of the Noosa Shire Council (NSC) and the State Planning Policy (2014), in terms of
demonstrating how the relevant stormwater pollutant reduction objectives will be met. Discharge
from the site must achieve pollutant load reduction targets (Table 1) and be demonstrated through
use of the appropriate modelling software.

                      Table 1 – Pollutant Reduction Targets for South East Queensland
          Pollutant Type                                   Reduction Objective
   Total Suspended Solids (TSS)     80% reduction in average annual load of pollutants
   Total Phosphorus (TP)            60% reduction in average annual load of pollutants
   Total Nitrogen (TN)              45% reduction in average annual load of pollutants
   Gross Pollutants (GP)            90% reduction in average annual load of pollutants
