Amended Stormwater Management Plan - Revision B 10.3.21

3. SEDIMENT & EROSION CONTROL




3.1 EROSION POTENTIAL


  Based on the completed Noosa Council Erosion Hazard Assessment Form, the proposal
  is classified as a “low risk” development for erosion potential see Appendix A for a copy
  of the completed form.

  Erosion and sediment control (ESC) measures will be required to be established and
  maintained in accordance with IECA’s standards of best practice. Preparation of a
  detailed ESC plan will be completed as part of the operational works submission.



4. SITE DRAINAGE INVESTIGATION




4.1 DESIGN RAINFALL INTENSITIES

Rainfall intensities were obtained from the Bureau of Meterology’s Rainfall Intensity Duration
Data (RIFD) for Noosa Heads, Queensland.

4.2 PERFORMANCE REQUIREMENTS

The performance requirements for the stormwater system include:
   • Development to be generally in accordance with QUDM (2016);
   • Major Design Storm is 100 year ARI event (1%AEP);
   • Minor Design Storm is 10 year ARI event; and (10%AEP)

These requirements will be complied with throughout the detailed design stage.
