A new digital planning tool is helping authorities to estimate the ground risk and cost of developing brownfield sites in Greater Manchester. <\/strong><\/p>\n\n\n\n

The Brownfields Ground Risk Calculator is designed to understand and communicate the scale of risk and cost associated with brownfield ground conditions.<\/p>\n\n\n\n

It shows the scale at which potential brownfield sites are expected to be affected by soil or groundwater contamination.<\/p>\n\n\n\n

It also evaluates geotechnical hazards, such as land stability and ground gases which can affect building design, and estimates the costs required to mitigate the risks.<\/p>\n\n\n

The calculator has been developed by scientists at the British Geological Survey (BGS) in collaboration with partners Greater Manchester Combined Authority (GMCA), Gateshead Council and the Environment Agency.<\/p>\n\n\n\n

The tool supports a range of uses and the Environment Agency will use the calculator to contribute to its understanding of the scale of regulatory effort required for land contamination risk management by its staff, over the next five years.<\/p>\n\n\n\n

BGS geoscientist, Dr Darren Beriro, says the tool has potential to help other local authorities in the UK to meet housing targets and protect green spaces more efficiently.<\/p>\n\n\n\t\t\t

He said: \u201cWhen developing post-industrial brownfield land, historic contamination often needs to be remediated to ensure the land will be safe, often at a significant cost to the developer or land owner.<\/p>\n

\u201cA closer look at brownfield sites in central Manchester for example, shows that some land is likely to be more expensive per hectare to remediate than others.<\/p>\n

\u201cWe know that decisions made early in the planning process can affect the viability of building new homes. These are likely to be more critical given the potential impact of COVID-19 and the pandemic on budgets and the housing sector.<\/p>\n

\u201cBy making the tool more widely available, we can help more public bodies, developers and land owners make informed decisions, early on.\u201d<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/blockquote>\n\t\t\t\n\n\n

The calculator works by using over thirty publicly available environmental datasets published by BGS, the Environment Agency and The Coal Authority.<\/p>\n\n\n\n

The conditions it considers go beyond those expected for typical developments, and are referred to as ‘abnormal’.<\/p>\n\n\n\n

Using the data, it produces a \u2018ground risk score\u2019 and remediation cost estimate for each site, and presents it in a geographical information system (GIS).<\/p>\n\n\n\n

Greater Manchester Combined Authority is working with the Greater Manchester Local Enterprise Partnership to support the \u2018Build Back Better\u2019 campaign, an initiative which sets out to build back the economy and create a better opportunity for a strong and successful recovery following the COVID-19 pandemic.<\/p>\n\n\n\t\t\t

Murray Carr, Director of Land and Property for Greater Manchester Combined Authority, said:<\/p>\n

\u201cWe have over 4,000 development sites in our existing housing land supply pipeline and a significant majority are on previously developed brownfield land and in sustainable locations. Due to the industrial legacy, there will be sites with contamination challenges.<\/p>\n

\u201cAssessing the viability of brownfields sites and likely risk from contamination will support the delivery of new homes across Greater Manchester, our partnership working with Homes England, the development industry and regulators such as the Environment Agency.\u201d<\/p>\n

\u201cOur strategy centred on the creation of new homes and regeneration in places such as town centres is more than bricks and mortar. It’s about reducing inequalities, improving the lives of our residents, and post COVID-19 it\u2019s building upon existing work to help us all to \u2018build back better\u2019.\u201d<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/blockquote>\n\t\t\t\n\n\n\n\n
