About the Chelmsford Moulsham Street Conservation Area
The Chelmsford Moulsham Street Conservation Area covers about 7.1 hectares and was designated by Chelmsford City Council in 1987. Inside the boundary are 17 listed buildings, all Grade II. Part of the area lies in flood zone 3, so an extension may need a flood risk assessment.
