1. INTRODUCTION
This report, the Stormwater Management Plan, details the proposed stormwater
management strategies for the proposed Unit development.
The stormwater Strategy is designed in accordance with the Noosa Council’s Stormwater
Planning Policy as well as the State Planning Policy.
2. SITE DESCRIPTION AND PROPOSED USE
The site is currently a vacant block of land of 594m2 . It is proposed (see Appendix A for
design drawings) that three units be constructed on site. When combined with paved
areas there is an approximate 455m2 of impermeable surface
The site is to be used for private residences to Appendix A for drawings detailing the
proposed location of Units.
3. PAVEMENT RUNOFF TREATMENT AND INFILTRATION
The runoff from all pavement areas shall be directed through a system of stormwater pits
and pipework to the LPOD identified as the Noosa Council Stormwater System, via the
Kerb and Channel in Willam Street.
4. STORMWATER QUANTITY
The rainfall data has been calculated as per QDUM and shows a non-worsening volume
of 6m3 of stormwater. Therefore, the stormwater design includes a 2000l detention tank
in each unit.
The minimum detention volume per unit shall be 2000L. Larger tanks may be used for
water harvesting and re-use, however, 2000L shall be made available for detention
volume in each tank.

Should the developer decide, there is enough room and fall to have the entire detention
tank underneath the driveway. Should this option be taken by the developer Lindsay
Consulting will provide and design drawing for an underground vessel tank.
Roof water shall be directed to the detention tank.

basin. It is essential that the gypsum is spread evenly over the entire surface for efficient treatment of the turbid water. DAM TO BE SPECIFIED ON SWMP/ESCP
Generally the gypsum should be applied at a rate of about 32 kgm per 100 cubic metres of detained turbid water, as per the adjacent table.

METHOD OF TESTING THE STORMWATER MAINTENANCE PROGRAM SHOULD ENSURE THEIR INTEGRITY IS RETAINED, ESPECIALLY WHERE CONSTRUCTED WITH STRAW
BALES. IN THE CASE OF BALES, THIS MIGHT REQUIRE THEIR REPLACEMENT EVERY TWO TO FOUR MONTHS.
The stormwater detained in the sediment basin will be tested at a suitable location that will be decided upon at the site. The sample should be taken at a location that has adequate
access so no sediment is resuspended while the testing is being conducted. 2. TRENCH THE CHECK DAM 200 MM INTO THE GROUND ACROSS ITS WHOLE WIDTH. WHERE ROCK IS USED, FILL THE

DAM.
METHOD OF DEWATERING
The sediment basin can be dewatered as soon as the water quality criteria met (refer table below). A pump is to be used to decant the basin with a floating inlet to prevent the
settled sediments from being removed from the basin. The pumping must cease prior to the settled sediments being drawn into the intake pipe, it is essential that materials from
the sediment layer are not discharged in the pumping process. STABILISE STOCKPILE
