Officials from the Environment Agency have raised concerns over plans to improve a Shropshire paragliding centre.
The scheme includes replacing the old farm buildings which are currently used as classrooms at the Melverley centre.
The site is in a flood-risk area, and the enviornment agency is concerned visitors could become trapped when water levels rise.
Councillors are due to discuss the scheme at a meeting on Tuesday.
Planning experts are backing the scheme saying it will be good for tourism.
