PURPOSE OF THIS DOCUMENT The purpose of this document is to satisfy the requirements of Site-Wide Condition E2 of S73 application (20/01129/ CV) as per our intention to discharge against the varied ZONE 5 planning permission. As such this document sets out a Site-wide Green Infrastructure Strategy, in order to ensure ZONE 5 the satisfactory provision of Green Infrastructure and Open Space across the development. The aims of this Site-wide Green Infrastructure Strategy are to: ZONE 1 ZONE 3 ZONE 3 • Identify and map the key attributes that contribute to ZONE 2 green infrastructure at Purfleet-on-Thames; ZONE 1 • Establish a vision and set of overarching principles for the planning and design of green infrastructure at ZONE 2 Purfleet-on-Thames, in order to inform the development of Design Codes and Detailed Design proposals; • Identify and map potential new and enhanced assets ZONE 4 ZONE 4 ZONE 6 ZONE 6 that are required to improve the functionality of the green infrastructure network, including opportunities for landscape and habitat enhancement and provision of new green spaces; ZONE 8 ZONE 7 ZONE 8 ZONE 7 ZONE 9 ZONE 9 • Provide detailed descriptions of key habitat types, including design principles and key species; • Set out how the Green Infrastructure will be delivered across the sub-zones of the masterplan, to form a well- connected and comprehensive network. 2017 CONSENTED OUTLINE MASTERPLAN 2020 MASTERPLAN WITH UPDATED SUB FRAMEWORK LOCATIONS 5 1 INTRODUCTION PURFLEET CENTRE REGENERATION 1.2 VISION & OBJECTIVES 1.2.1.
