This is Session #10 of the ‘Stormwater Fundamental’ series in 2024, focussing on Development Assessment. Within Australia, development applications are commonly required to demonstrate how ‘post construction’ (or ‘operational phase’) stormwater quality targets will be achieved. Stormwater quality management plans/ reports (and associated information) are subsequently prepared in support of development applications – and submitted to local government (and/ or other regulatory authorities) for assessment and, if appropriate, approval. Development Assessment personnel subsequently have the challenging task of undertaking a rapid review of technical information (including reporting, drawings and modelling files) to determine whether the proposed strategy (and associated SCMs) is appropriate – and provide suitable development approval conditions. The session will focus on the following key areas (for both proprietary and non-proprietary SCMs): – Modelling ‘tricks’ that are commonly applied that will exaggerate the performance of SCMs, and how to quickly identify them – Design, implementation, and management mistakes that are commonly made that invariably lead to the poor function of SCMs (including several ‘real world’ examples) – Approval conditions to consider applying to support the appropriate long-term function of SCMs proposed as part of new development. The 45-minute session will include a short presentation by Ocean Protect’s Harout Tcherkezian and Brad Dalrymple, followed by Q&A with attendees. A certificate of CPD can be provided to attendees upon request.
