During the February 2014 floods, Basingstoke Borough Council opened an emergency centre to deal with the crisis in its catchment area. Combining OS base mapping with the Council’s Local Land and Property Gazetteer as well as partner data gave a detailed picture of the flood situation to allocate resources effectively.
What were the challenges?
- Co-ordinating emergency response to an immediate flood situation.
- Identifying flooding hotspots – including river flooding and groundwater flooding.
- Creating a data sharing platform on which information could be updated and monitored.
- Allocating emergency resources to best effect.
What was the solution?
OS base mapping, together with the Council’s Local Land and Property Gazetteer (LLPG), was merged with data from a number of partners, including Hampshire Fire and Rescue; Hampshire Constabulary; Hampshire County Council; the Armed Services; Environment Agency and Scottish & Southern Energy. Control room staff then had an overview of the flood situation which greatly helped with tactical decision making.
What were the outcomes?
- Resources could be allocated precisely where needed.
- The changing situation was easily monitored and updated in real time by people on site.
- Overlaying flood plain data identified further properties and areas at risk of flooding.
- Sharing data with emergency services and other partners enabled joint access to common information, and a co-ordinated emergency response.
- Helped to identify 86 homes needing evacuation. 12,000 sandbags were distributed and 41 million litres of water tankered away.
