Southlands Development – Stage 3 (Lot 9) Community Fact Sheet April 2021 Orica has owned land at Southlands since 1980, and in recent years has subdivided and sold some of this prime industrial land for industrial and warehouse use servicing Port Botany and the Sydney Metropolitan Area. Orica will continue to hold a small amount of land to accommodate infrastructure for Orica’s ongoing Botany Groundwater Cleanup Project. There is demand for industrial land in the Botany area and Orica decided to develop the Southlands site consistent with its industrial zoning. Orica is keen to see the vacant land turned into productive space. What is Southlands? Southlands is an approximately 18 hectare site situated directly south-west of the Botany Industrial Park fronting McPherson Street, Banksmeadow. The site lies entirely within the Bayside Local Government Area. It is zoned IN1 (general industrial), and is located approximately 1 km away from the Port of Botany and 500 m north of the northern shores of Botany Bay. Lot 9 at McPherson Street was created as a compensatory flood storage basin as part of Southlands Remediation and Redevelopment Project in 2016. Southlands Lot 9 Stage 3 Development In 2019, Orica applied for State Significant Development approval for Lot 9 of the Southlands site (also known as 28 McPherson Street, Banksmeadow). Lot 9 is the location of the compensatory flood storage basin. Orica sought development approval for a warehouse development comprising warehouse buildings and hardstand/car parking constructed on a suspended concrete platform above the existing compensatory flood storage basin. The development includes easements benefiting Orica around the perimeter of the suspended concrete platform and beneath it. Lots 10 and 11, in which infrastructure associated with the Botany Groundwater Cleanup Project is located, are unaffected by the development and will be retained by Orica. Southlands Development Project Fact Sheet – Stage 3 (Lot 9), April 2021 available at www.orica.com/Botany General Southlands Development – Stage 3 (Lot 9) These easements and lots will allow Orica to continue to monitor and maintain the infrastructure and the compensatory flood detention basin. The easements also provide space for future groundwater monitoring and remediation works if required. Key features of the Master Plan: Industrial development over new suspended deck The public exhibition of the Environmental Impact Statement (EIS) was published by the Department of Planning Industry and Environment in April 2020. Project Approval was granted in April 2021. Orica does not plan to implement the development; that will be done by a prospective future purchaser. Key Points of the Proposed Development • The proposed development does not propose to concrete over the top of the Southlands compensatory flood storage basin. • A suspended concrete platform will be constructed above the compensatory flood storage basin. • The flood-mitigating function of the compensatory flood storage basin will not be adversely affected by the development. • Access beneath the elevated concrete platform will be restricted to authorised persons. This will be controlled by a fence and locked gates. • The proposed development will not materially affect Botany Groundwater Cleanup Project. Southlands Development Project Fact Sheet – Stage 3 (Lot 9), April 2021 available at www.orica.com/Botany General Southlands Development – Stage 3 (Lot 9) • The perimeter of the suspended concrete deck is designed with setbacks on all sides, which will allow service vehicles to be driven around the perimeter (e.g., for maintenance, investigation or remediation). • The height of the suspended concrete platform is designed with 2.5 m head clearance to allow vehicles such as a small push-probe rig under the platform should investigation or remediation activities such as coring and well installation be required. Initial Concept Plan - Cross Section Synergy with Orica's Ongoing Groundwater Cleanup Activities Southlands plays an important role in the Orica Botany Groundwater Cleanup Project. Development of the site has been planned and implemented to enable: • Ongoing operation and maintenance of the groundwater containment system installed along the Southlands McPherson Street boundary; • Ongoing hydraulic and chemical monitoring; and • Potential for future application of other groundwater remediation technologies.
