5.0     STORMWATER DRAINAGE

The site currently grades to the rear towards Project Avenue. It is proposed to discharge site runoff
to the existing stormwater gully pits located in Project Avenue.

The proposed layout will produce an increase in impervious areas over the existing and this will
cause an increase in site runoff. It is proposed to provide on-site detention via a tank located under
the proposed service station shop.

Site stormwater runoff from the carpark, roof and ground areas will be treated for quality with
Stormwater 360 Stormfilter cartridges and filter baskets fitted to field inlets. The filter cartridges will
be located within the proposed detention tank.

The hardstand under the fuel canopy and the tanker filling are during filling operations will be
directed to a separate sump.

Concept civil engineering plans have been prepared and are enclosed in Appendix C of this report
to illustrate anticipated servicing arrangements for the proposed development. It should be noted
that these plans are preliminary only and will be subject to confirmation during detailed design.

Additional details for stormwater management can be found in the site based Stormwater
Management Plan B16239CR002 prepared by Lambert & Rehbein (SEQ) Pty Ltd.
