Attachment 3 - Stormwater Management Plan 1856-SBSMP-01 v5 (December 2019) · RAL18/0023

5.0 CONCLUSION

This site-based stormwater management plan has reviewed the stormwater quality
management at the proposed development at Noosaville, Queensland.


Based on this assessment the following conclusions have been made:


· The proposed development includes Stormwater Quality Improvement Devices being
   bioretention basins and vegetated swales treating post-developed flows from the
   proposed road reserve only, in accordance with the Qld SPP (2017). The total amount
   of treatment devices are as follows:
        o    Vegetated swale (total length) = 20m
        o    Buffered area = 50m2
        o    Bioretention basin (total area) = 243m2


   In the event the individual lots created by this subdivision are developed, they will require
   SQIDs to satisfy stormwater runoff pollutant removal targets for each specific lot.

In summary, stormwater leaving the site will satisfy the pollutant removal criteria in Council’s
Planning Scheme and the Qld SPP.
