The Draft Development Control Plan 2014 – Part 8.2 Stormwater and Floodplain Management and associated technical manuals, such as the Stormwater and Floodplain Management Technical Manual and Water Sensitive Urban Design Guidelines went on public exhibition from 18 February 2015 to the 20 March 2015 for community comment.

What is a Draft Development Control Plan (DCP)

A Development Control Plan is a document which contains a set of detailed planning and design guidelines that complements the controls of a local environmental plan (LEP).

What is the Purpose of Draft DCP 2014 – Part 8.2 Stormwater and Floodplain Management?
  • To amalgamate existing DCP Parts 8.2 Stormwater Management and 8.6 Floodplain Management into a single cohesive and comprehensive DCP Part
  • Introduce Water Sensitive Urban Design (WSUD) controls for major developments
  • Provide more flexibility in the application of flood management controls.
  • Remove all technical material into separate documents to be read in conjunction with the new DCP Part. These are the Stormwater and Floodplain Management Technical Manual and Water Sensitive Urban Design Guidelines

The draft DCP Part:

  • Updates Council’s current stormwater drainage and WSUD controls to reflect current industry standards
  • Improves readability of the Part
  • Simplifies the stormwater controls applying to all development classes
  • Incorporates Water Sensitive Urban Design into the Park
  • Improves flexibility of controls related to floodplain management

Stormwater management controls have been reviewed. Examples of changes to the controls include:

  • Drainage easement will no longer be required for minor development. Alternative systems such as an absorption or charged system will be able to be used.
  • Design requirements for on – site detention with respect to major development has been clarified and updated to industry standards.

Flood management controls have been reviewed . Examples of changes to the controls include:

  • Consideration of flood management controls are to be included in a Flood Impact Statement
  • For minor development that satisfies requirements in the Stormwater and Floodplain Technical Manual there will be no requirement for a full scale flood study to be undertaken.

Controls relating to WSUD are to be incorporated into the DCP for the first time and will apply to:

  • Land in a business or industrial zone if the development is greater than 1500sqm . This will include residential flat buildings and mixed use developments
  • Development on land for SP2 Infrastructure such as schools , hospitals and other institutions
  • Above ground car parks accommodation more than 50 car spaces
  • Land subdivision resulting in the creation of 5 or more lots

The controls include requirements for:

  • The submission of a WSUD Strategy Plan
  • Water treatment measures that will satisfy specific pollutants targets
  • Water re – use by ensuring there is sufficient rain water storage to meet 50% of the non-portable water demand of the development.
