Plans to divert a stream near Eagle Close on the Harlands Estate, Uckfield, are before Wealden Council.
The scheme has been submitted by Torres de mar Investments in a bid to prevent gardens eroding during floods.
The proposal is to cut a new channel to link the small Chalybeate Spring, near Mallard Drive/Eagle Close, with the more western Framfield Stream.
Torres de mar Investments built the Harlands Estate and owns the field the channel would cross. The planning application says it is currently scrubland and not in use.
It also says: “The new channel will be approximately 40-50 metres in length … and will divert a significant amount of flow to the Framfield Stream away from the rear of the houses at Eagles Close.
“This would change a small area of this field from being an open field to a watercourse.”
A couple, who live in Eagle Close, have formally supported the application saying they would be pleased to see any re-routing or diversions to the stream to reduce continued erosion to the bank which has led to destabilisation of their boundary fence and patio.
The planning application says spoil excavated from the ditch would be spread along the banks of the relief ditch with no noticeable increase in elevation of the land. “Therefore no additional flood risks will be created.”
