Canada Bay Flood Management Conditions

2. Driveway & Car Park Design Longitudinal sections through both edges and centre of the proposed driveway/vehicular crossing from the centre line or the crest of the road Saint Georges Crescent, whichever level is greater to the basement floor and loading bay shall be prepared by a suitably qualified engineer demonstrating compliance with the scraping provisions for the B99 vehicle and the Heavy Rigid Vehicle (HRV) as stipulated in AS/NZS2890.1 and AS2890.2. The longitudinal sections shall include: i. All changes in levels and gradients e.g. lip of gutter, gutter invert, kerb layback, edge of footpath and at the property boundary. ii. Footpath crossfall shall have a maximum of 2.5% graded…

1. Overland Flow Impact The submitted architectural plans and stormwater management report have not clearly demonstrated or assessed whether any existing upstream catchment overland flow during the 1% AEP storm event may impact the proposed finished floor level and basement floor protection. Accordingly, a detailed hydrologic and hydraulic assessment prepared by a suitably qualified engineer shall be provided to demonstrate that the proposed development incorporates adequate protection measures for both the building and basement against potential 1% AEP overland flow impacts. It is recommended that the Applicant’s engineer considers the upstream catchment, including any existing stormwater…
