Stormwater drainage
Stormwater runoff from any subdivision and/or individual site must be directed to a lawful discharge point. There must be:
- no net increase in peak flows of stormwater runoff from any site during weather events from Q2 to Q100 storm rating
- no adverse impact external to the site either from redirection, concentration and/or increase in flood levels.
Our City Plan Land Development Guidelines and the Queensland Urban Drainage Manual provide information for engineers and stormwater designers to help with the planning, design and management of urban stormwater drainage systems.
Building sites
Stormwater runoff from building sites must also be collected and directed to a lawful discharge point. For stormwater associated with building work, please refer to the Building Code of Australia. For stormwater associated with City of Gold Coast services, please refer to our Land Development Guidelines.
Stormwater drainage associated with building works that connect to Council's system requires an Operational Works (OPW) application, except for the following:
- property drainage other than connection to the existing concrete kerb and channel
- existing stormwater pit or inter-allotment drain where the catchment drainage is less than 500 square metres.
The design of the proposed drainage system for the building must:
- not adversely affect the upstream drainage
- ensure the downstream drainage system is capable of adequately catering for the discharge of the additional flow produced as a result of the building or structure.
