HISTORICAL MAPS CAN HELP UNLOCK AN EXPLOSIVE LEGAC
12 June 2008, 5:19pm
As East London sees a controlled explosion on the biggest World War II bomb to be found in the city for 30 years, Landmark Information Group is making a new layer of historical mapping available to help track unexploded ordnance (UXO) such as this.
It is estimated that as many as 10% of the bombs dropped during WWII did not explode, leaving behind a risky legacy for anyone involved in property development and the related environmental due diligence industries. In particular, major construction sites using machinery at substantial depths stand a chance of unearthing an unwelcome memento from the war – especially on urban, brownfield developments.
David Mole, MD Landmark Environment, says: “We believe that more than 21,000 sites may contain unexploded bombs. Those cities worst hit by bombing during the war present the biggest risk, including London, Plymouth, Bristol, Manchester and Birmingham. Crucially, Landmark has been able to unlock this data by digitising thousands of maps at a scale of 1:2,500 and cross referencing with known ruin sites from World War II.”
New historical aerial photography flown by the Royal Air Force between 1944 and 1951 is also now available for key cities and installations across the UK. This allows users to identify WWII bomb damage, thereby indicating additional areas of potential risk. This database has been created by digitising photography made available by the British Library and supported by Landmark’s own archive.
“This is all valuable intelligence for property developers who may face an increased risk of detonating one of the thousands of unexploded bombs in the country,” adds David. “Incidents such as this one at Sugar House Lane in East London1 - where a digger clearing ground for the 2012 Olympics unearthed the 1,000kg device - demonstrate the need for robust information on potential UXO risks. We expect to see an increasing demand for robust desk study reports on topics such as this.”
Historical Aerial Photographs are available from £10 via the Envirocheck website www.envirocheck.co.uk. For further information on Landmark’s historical map archive and other land and property search information, please call 0844 844 9952 or visit www.envirocheck.co.uk

Each month we select a hot topic and a leading figure in the industry to write about it.HAVE WE REALLY LEARNT THE LESSONS FROM LAST YEAR’S FLOODS?
Flooding costs associated with extreme weather, both financial and emotional, have increased considerably over the last decade, and experts have predicted this trend is set to continue.
Paul Livett, Chairman of GroundSure looks into how increasing the use of flood risk information in property transactions can help to ensure both residential and commercial transactions are conducted on a truly informed basis, with buyers being made aware of environmental risks prior to purchase.
Over 2.2 million homes and small businesses in the UK are located in areas considered at risk of flooding, and the Association of British Insurers (ABI) has said that 570,000 of these face a high risk of flooding. The floods in June and July last year left approximately 48,000 households… More…
