EBBSFLEET SUSTAINABILITY ASSESSMENT
// Public Realm+ Infrastructure
Engagement Draft// May 2024
One Page Design Guidance Public Realm & Infrastructure
Carbon & Energy
The primary focus is on the the delivery of Net Zero Carbon public realm and infrastructure. Such schemes should:
• Utilise renewable energy sources such as solar panels PV cells to ensure a low operational carbon demand
• Use low embodied carbon materials that are highly sustainable, renewable or made of high recycled content such as timber, GGBS concrete and recycled steel. Schemes should make reference to how materials are being manufactured, procured, transported and constructed onsite to reduce Upfront Carbon figures. Questions should be asked about what are the big ticket carbon saving materials being used, their specifications & strategies for repair, maintenance & replacement of the homes to reduce in-use embodied carbon
Water
The primary focus is to develop public realm and infrastructure to be climate resilience, and minimise water use. Schemes should demonstrate:
• Evidence of blue / green infrastructure and Sustainable Urban Drainage Systems (SuDS) that capture stormwater and mitigate flooding
• Connections to existing SuDS infrastructure, where possible
• Evidence of permeable hard landscape surfaces
• Provision of rainwater collection such as water butts to infrastructure buildings and Grey water recycling measures
Additional guidance can be found here:
• Susdrain, Delivering SuDS (including retrofitting SuDS)
• Kent County Council Drainage and Planning policy statement
• Susdrain, Water People Places
Waste & Materials
The primary focus is to construct infrastructure with circular economy sustainable and healthy materials minimise domestic waste streams. Schemes should evidence:
• Appropriately sized, easily storage provision for recycled waste streams
• Specify reused or recycled materials in dwellings and
• Demonstrate design for deconstruction or adaptability and Offsite Construction
Health & Wellbeing
The primary focus is to develop healthy neighbourhoods with active travel and low carbon and pollution infrastructure, that allow residents to be within a 5 minute walk of day to day amenities and good access to public open space.
• The public realm should be designed with a clear design hierarchy of pedestrian, cycle and public transport routes
Materials
construct public realm and economy principles, promote materials and opportunities to streams.
easily accessible and secure recycled food waste and general
recycled and responsibly sourced and landscape treatment material efficiency, high PMV, adaptability of homes with DfMA / MMC methods
• Align design proposals with the Design for Ebbsfleet Character Guide
• Align design proposals with the Ebbsfleet’s Park Design Criteria
• Align design proposals with the Ebbsfleet Public Realm Strategy
Natural Environment
The primary focus is to construct the public realm with green infrastructure that contributes to climate resilience and provides opportunities to enable residents and visitors to connect with nature and make sustainable lifestyle choices. Applicants should provide evidence of:
• Diversity of native and drought resistance species of planting
• Creation and provision of habitats in the landscape
• Soft landscaping and Tree Canopy Cover strategies in alignment with EDC’S Public Realm Strategy
• Connecting new public realm to existing
• Adoption of minimum 10% Biodiversity Net Gain and target 0.4 or greater Urban Greening Factor opportunities

Accessibility
Accessibility
Project has facilitated co-design events early in the design process to up-skill the community on design, and enable them to engage in the codesign of the project.`
Project has utilised a digital engagement platform throughout the design process to provide a portal for all briefing and community engagement activities, and to provide feedback on community proposals and ideas.
Project has included an access consultant to enable best practice accessibility within the project.
For Public Realm, the project has applied the public building section of the London Legacy Development Corporation’s Inclusive Design Standards.
Arts and Culture
Design teams has reviewed the Ebbsfleet Public Art Strategy, and integrated the Ebbsfleet public art principles into the project.
