**WSSC Front Foot Benefit Charges**
In the year following completion of water and/or sewer main construction by WSSC, property is assessed a WSSC Front Foot Benefit Charge (FFBC), as required by law, to repay funds borrowed to finance construction. WSSC’s FFBC appears on the property tax bill for a predetermined number of years, depending on bond issue (presently 30 years), but may be paid off in full at any time. WSSC’s FFBC is determined by multiplying the property’s assessable footage by the rate per foot for the appropriate classification -- rates change yearly. Irregularly shaped lots are assessed using average footage of neighboring properties. In areas designated by County Governments as Service Area 5 or 6, WSSC places the assessment in hiatus (suspends) until such time as County policy will allow service. In Service Areas 1 through 4, existing houses with satisfactory well and/or septic systems will be granted an exemption from the assessment until the property owner requests service from a WSSCbuilt water main or sewer line. Upon connecting (hook-up) to the WSSC-built water and/or sewer mains, any and all property not previously assessed becomes immediately subject to FFBC.
