Zoning values are added to the base score when "Include Zoning in Scores" is toggled on. The scenario sliders never lower a parcel's existing zoning value. Sliding to Special Decision, Overlay, or By-right raises each parcel's value to that scenario's level only if its current zoning scores below it.
