MORE information about flood risk at the proposed £3m expansion of Upton Marina has been sent to the Environment Agency.

Marina owners Walton Marine have responded to a letter to Malvern Hills District Council from Elizabeth Hill, EA team leader for development planning, in which she said "the general principle of flood risk management as set out in the flood risk assessment is acceptable".

However, she also requested record 1947 flood levels be used to determine the project's functional flood plain, where government guidance says any development should be "wholly exceptional".

The letter stated that the agency is only likely to consider consent for modifications to flood defences if it sees redundant sections removed or capacity in-creased elsewhere on the flood plain to compensate.

Walton Marine had already sent details of flood levels seen on average once every century, a "one-in-100" event, as part of its original Environmen-tal Impact Assessment, but had to send more data via hydrological consultants Jeremy Benn Associates on one-in-five-year, one-in-10-year, one-in-25 year and one-in-50-year flood events.

The letter warned the new information could affect the extent of acceptable developable area.

Conditions aimed at pollution prevention were also requested in the letter, which states that a surface water drainage system must be agreed with the agency before work starts.

Marina manager Steve Arber said all extra information required by the agency had been sent to it and he is now awaiting a response. He said the new data had not thrown up any problems, and described the conditions as "fairly standard".
