Hi, Welcome to OpenStreetMap.

Sorry but your landuse=residential area covers a lot of other different types of areas. Thus I've removed it. The tag landuse=residential is used when mapping land areas used only as residential.

The boundary line for Marlborough is here:- https://www.openstreetmap.org/relation/3411516.

If you could explain what you hoped to achieve maybe I could help.

Regards Bernard.
