1.            Preamble

Erosion and sediment control on building sites

Builders must not pollute the environment. The Environmental Protection Act provides for
penalties for persons or entities causing environmental harm.

Soil erosion on building sites can be a major source of sediment pollution (environmental
harm) in our watercourses. A single building site can lose up to four truckloads of soil in one
storm. Washed from the sites into stormwater drains, this sediment can cause flooding and
also affects the water quality and the fish stocks in our creeks, lakes and the Noosa River
system.

Preventing sediment run-off from building sites is one of a number of ways that Council and
industry are improving our watercourses.

Effective on-site erosion and sediment control provides the following benefits—


      A better looking, more marketable site;
      Improved wet weather working conditions;
      Reduced stockpile losses;
      Less mud and dust problems;
      Reduced clean-up costs;
      Fewer public complaints;
      Better public image;
      Cleaner watercourses; and
      Better fishing and swimming in our nearby watercourses.
