           INTRODUCTION

Bax Engineering has been commissioned by Michael and Judy Klobas to assess the existing stormwater
drainage system and provide a stormwater management plan for the proposed residential development as
shown on the Chris Clout Design plans C0.0 to 7.0; located at 8 Stevens Street, Sunshine Beach Queensland
(Lot 696 on SP279875). The plan is in response to the Noosa Council information request (MCU18-0001) which
requires the development to collect and discharge/infiltrate stormwater and ensure sufficient capacity is
provided in the existing infiltration system. The plan will also demonstrate the existing stormwater easement
along the eastern rear boundary is no longer required.

The site (as identified in Figure 1) covers an area of 506m2 and falls to the east at a slope of approximately 7%.
Any existing runoff from the site currently flows to an open swale and engineered grated drain formed as part
of the shared concrete driveway. Catchment flows are then diverted in to an underground infiltration tank
system via a field inlet pit. It is noted that any calculations have been based on the site area only and no
external catchments have been considered.
