Drainage requirements for developments

Stormwater and design requirements

We have a stormwater drainage policy to control:

• the manner in which proposed developments discharge their stormwater runoff
• unnecessary surface flows
• overburdening of existing infrastructures

Assessment of engineering design plans and calculations by Council is only necessary if specifically requested by us through a development’s Legal Point of Discharge, Planning Permit Conditions or otherwise. We generally assess engineering plans under the following circumstances:

• Internal drainage systems where an On-Site Detention, Pump or Pressurised System is required. Additionally, where Council deems a development may pose a flood risk to an adjoining property, assessment of the drainage design plans may be required.
• Where a development’s Legal Point of Discharge or Planning Permit Conditions requires the construction of a new Council asset, submission of detailed engineering design plans, prepared by a suitably qualified Civil Engineer, is required (e.g. new barrel drains, footpaths, or Right of Way constructions etc).

To apply, please complete the relevant form:

• Engineering Plan Check Application - both Internal and Civil Works
• Engineering Plan Check Application - Internal Works
• Engineering Plan Check Application - Civil Works

Please attach all design plans, calculations, endorsed Condition 1 plan, and any other relevant supporting documentation.
