I have a layer named 'Landuse' in TOC. Symbology type is 'Unique value" for the field 'Landuse', for example:

• Residential
• Commercial
• Public
• Recreational
• Etc.

Is there any way to automatically remove Commercial (for example) since actually there is no 'Commercial' polygon in 'Landuse' layer by existing tool or by Arcpy coding? P.s: Because there are many unique values in the 'Landuse' layer, and I have to do it many times, so that I dont want to do it manually.
