If you want to discharge stormwater onto the State road reservation, you will require approval from the Department of State Growth.
This may be applicable from a range of aspects that have an impact upon the State reservation drainage system, for example:
Depending on the impact to the State road reservation, one or two separate approvals may 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.
Drainage discharge consent is required under Section 17B (1) of the Roads and Jetties Act 1935 for the concentration and discharge of drainage in the State road reservation.
You will need to fill in and submit an application:
Drainage works relate to the construction of new and/or modification of existing drainage infrastructure within the State road reservation.
