Council provide Stormwater Point of Discharge to accommodate a single dwelling with no more than 40% site coverage.
Development with site coverage greater than 40% will require the provision of a Stormwater Detention System with a volume capable of retarding the 10 year ARI flow from the development site back to a 5 year ARI pre-development value.
Water Sensitive Urban Design principles (WSUD) can be incorporated into the drainage design to reduce the site outflow to the required 5 year ARI pre-development value.
Where a site is subject to a Planning Permit for development, the discharge location may be subject to alteration. All Planning Permit conditions must be complied with to the satisfaction of the Engineering Services Manager.
