This may be applicable from a range of aspects that have an impact upon the State reservation drainage system, for example:

  • Increasing the impervious surface area to be drained, i.e. new dwellings, driveways and subdivisions.
  • Construction of new stormwater infrastructure within the State road reservation.
  • Relocation or modification of existing stormwater infrastructure within the State road reservation.

Depending on the impact to the State road reservation, one or two separate approvals may be required:

  • If no works are required within the State road reservation, only a stormwater discharge consent letter is required.
  • If works are required within the State road reservation for drainage, a service works permit and stormwater discharge consent letter will be required.

Applications must include a drainage plan, including catchment area, pre & post development flows and preliminary drainage designs for any area discharging to the State road reserve or modification of the existing highway drainage system.

Note that the flood protection criteria vary across each of the State road categories, to determine which criteria is applicable, please refer to the Department’s Technical Specification T8, which can be located: https://www.transport.tas.gov.au/roads_and_traffic_management/contractor_and_industry_information/professional_service_specifications

Applications must be received by the Department of State Growth at least 20 business days before your expected start date for works, to allow enough time to assess your application.

2Step 2 - Works are required within the State road reservation for drainage
