What are the impacts?                      SEE FACT SHEET 2



Soil, sediment and litter from building sites can be major
sources of stormwater pollution, and can cause:
•    negative impacts on recreational fishing and
     the seafood industry
•    sediment build-up within waterways which
     can lead to weed growth
•    loss of valuable topsoil
•    significant public safety problems when washed

•    blocked drains and water sensitive urban design
     features leading to flooding and increased
     maintenance costs to the community
•    significant harm to the environment of freshwater
     and marine systems through the loss of valuable
     seagrass habitat for marine creatures
•    public health issues from increased algal blooms
•    reduced recreational opportunities due to increased
     turbidity

Erosion and sediment control on residential building sites                                                   SEE FACT SHEET 2



Principles of effective stormwater pollution control include:
•    sensible site planning
•    diversion of up-slope water (where appropriate)
•    stabilised site entry/exit point
•    minimisation of site disturbance and duration of
     disturbance
•    installation of sediment controls along the lower
     edge of the site
•    appropriate location and protection of stockpiles
•    early connection of roofwater downpipes
•    trap on-site run-off from tool, paint and concrete
     washing and brick, tile and concrete cutting
•    continual monitoring and maintenance of all
     control measures
•    compaction of backfilled trenches
•    revegetation and stabilisation of the site
•    development and implementation of Erosion
     and Sediment Control Management Plans                                                                                      ✓
     when appropriate.                                          Control measures in place on a residential building site
