This ASDDR provides confirmation that the SSD_ 7709 Mod1 Proposal stormwater systemmeets the requirements and principles set out in the approved Stormwater DesignDevelopment Report (SDDR) . The ASDDR confirms the following design principles andoperational requirements of the stormwater management for the proposed facility: • Management of stormwater quantity • Management of stormwater quality; and • Flooding Considerations. The consent authority is the DPIE. The proposed facilities are located within theMoorebank Intermodal Precinct West precinct (MPW Precinct), originally approved underSSD_ 7709, dated 11 November 2019. The Mod1 approval was granted by DPIE on 24December 2020. The engineering design for this project and included in this report has been completed andcoordinated with the MPW Precinct wide Stormwater Management Strategy and WaterSensitive Urban Design (WSUD) requirements as detailed in the approved SDDR (referCostin Roe Consulting report Co13455.07-02a.rpt) required of SSD 7709 conditions ofconsent (CoC) B4, B5, B6 and associated conditions to CoC B28 . Reference to AnnexureB should be made for confirmation of compliance with the conditions of consent. Revision B of this ASDDR incorporates the drainage engineering aspects of the JNDCwarehouse expansion. ## B DEVELOPMENT SITE ### B.1 Proposed Development The proposed development comprises two sites with automated facilities known as JanusRegional (JR) and Janus National (JN) . Both sites are adjacent and situated with the centralthird of the MPW Precinct, with JR to the north and JN to the south. The site’s comprise landareas of 14.5 Ha for JR, and 11.5 Ha for JN. The proposed Warehouse and DistributionFacility will comprise State-of-the
