About the Erith Riverside Conservation Area
The Erith Riverside Conservation Area covers about 3.2 hectares and was designated by London Borough of Bexley in 1995. Inside the boundary is 1 listed building, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
