Washington Revised Code Title 86. Flood Control § 86.15.176. Service charges authorized--Disposition of revenue

The supervisors may provide by resolution for revenues by fixing rates and charges for the furnishing of service to those served or receiving benefits from a flood control improvement including public entities, except as otherwise provided in RCW 90.03.525. The service charge shall be uniform for the same class of benefits or service. In classifying services furnished or benefits received the board may in its discretion consider the character and use of land and its water runoff characteristics and any other matters that present a reasonable difference as a ground for distinction. Service charges shall be applicable to a zone or participating zones. The disposition of all revenue from service charges shall be in accordance with RCW 86.15.130.
