Log in to see the plans as drawnSediment basin sizing has been calculated using the procedure outlined in Appendix B of IECA
guidelines and the soil loss equation (RUSLE) in Appendix E. Individual spreadsheet calculations
are attached for each of the above catchments at the back of this report – ATTACHMENT A.
Note that whilst area 2 & 4 ultimately discharge to the same location each area will have its own
sediment basin/containment area, although it may also be possible to utilise the existing dam in lot
9 for this purpose.
It is not proposed to construct sediment basins for individual lot house pads and driveways.
3. Conclusions and Recommendations
As outlined above, the majority of the site is considered a low erosion risk. Notwithstanding
sediment basins will be constructed and maintained during the bulk earthworks operations where
possible and as outline in the design plans.
