Most properties are subject to front foot benefit charges if they are abutted by WSSC water and/or sewer lines. However, there are certain properties abutted by WSSC water and/or sewer lines which are exempt from FFBC charges. There are other properties whose FFBC charges are suspended until a change occurs in the property’s classification, use or designation or the property connects to WSSC lines.
