Dear John,<br />
Please find the following response to your email dated 10 September 2009<br />
The upstream in-channel <strong>flood</strong> <strong>level</strong> taken prior tothe Bristol Frome entering the culvert is given in<br />
the following table (from our Halcrow 2008 model):<br />
Reference Node Fr0_wade<br />

Street culvert<br />
entrance<br />
100y FL (mAOD) 8.89<br />

Please note that the results of the Dove Lane FRA model are more conservative <strong>and</strong> those have<br />
been used in our <strong>Flood</strong> Map. Although we are unable to provide this <strong>data</strong> you could contact Buro<br />

In addition, please find a <strong>flood</strong> depth map attached <strong>for</strong> the 1 in 1000 year <strong>flood</strong> event on the Bristol<br />
Frome at the location in question. (There is no predicted <strong>flood</strong>ing in the 1 in 100 year <strong>flood</strong> event<br />
as the culvert is expected to have the capacity.)<br />
