Originally published in 2008, the BPESC has been periodically updated to ensure that the document remains current and continues to serve as an essential reference for best practice ESC planning and management within Australia.
The 2025 version captures a range of updates, user feedback, and amendments made since the original publication in 2008.
This version provides an up to date, user friendly resource that reflects current terminology and climate changes.
Key changes to the 2025 version include:
- Consolidation into a single document (no longer 3 books)
- Inclusion of Appendix P within the main document
- Updated rainfall terminology consistent with the Bureau of Meteorology and Australian Rainfall and Runoff
- Updated and additional rainfall design values
- Updated rainfall erosivity (R-factors) values
- Consistent sediment control standard
- Additional guidance regarding soil binders, Type B basin dewatering and stockpile management
- Revised soil loss limit for catchments greater than 10,000m2
Books 4-6 remain unchanged at this stage but may be revised in the future to align with the update introduced in this edition.
