The number of people the Environment Agency can contact in times of flooding has gone down - despite a drive to get people to sign up to a dedicated hotline.
The figures were revealed at a meeting of the Boston Town Area Committee on Wednesday when Flood Reslience Advisor Rachael McMahon spoke to councillors.
She told how the percentage of people who could be contacted by landlines supplied by the phone companies had gone down from 49 per cent to 48 per cent (a total of 7,903 down to 7,720).
The number of people who have registered for floodline has gone up by 67 from 2,576 to 2,643 - a total of only 16 per cent of the16,029 properties at risk.
However, there are still 5,550 properties at risk with no contact details.
In a presentation on the Floodline Rachael said: “It’s had fantastic coverage.
She added: “We’re getting support and we’re getting business time to different organisations but for whatever reason people are choosing not to register.”
The main increase in registrations took place in the Fenside ward, where there were 23 new contacts between April and June – this was attributed to a flood warden presence in the area.
This was followed by the Central ward with 16 new registrations and Witham ward with six.
She said Floodline had visited 30-plus local groups and attended 25-plus events and meetings.
Future plans include getting further coverage along with increasing flood wardens and Emergency Planning Groups in areas around Boston to promote the system.
There was also plans to align activities with a nationwide flood campaign taking place at the beginning of November.
