Agricultural properties are not assessed until a connection to WSSC service is made. They are then assessed at the rate(s) and term(s) in effect at the time of connection. Once the property is connected to WSSC water and/or sewer lines, it is assessed at the base rate for actual pipe abutment up to a maximum of 150 feet for each connection. However, agricultural properties with more than one connection will not be assessed for more than 300 feet.

The connected agricultural property above has 450 feet of street frontage, but only 325 feet is abutted by WSSC lines. Therefore its assessment for 325 feet would be as follows: first 150 feet at base rate, remaining 175 feet is placed in an agricultural-exempt status.
