WAT §46200: The commissioners shall prepare and certify assessment rolls which shall contain: (a) A description of each tract held in separate ownership by legal subdivisions, governmental surveys, or other bound

The commissioners shall prepare and certify assessment rolls which shall contain: (a) A description of each tract held in separate ownership by legal subdivisions, governmental surveys, or other boundaries sufficient to identify it. If any area composed of more than one tract held in separate ownership is not assessed because the land therein will not be benefited by the expenditure of the funds to be raised by the assessment, a description of the area as a whole without a description of each tract shall be sufficient. (b) The number of acres in each tract. (c) The name and address of the owner of each tract, if known, and if unknown, that fact. No mistake or error in the name of the owner or supposed owner of the property assessed, and no mistake in any other particular, shall render the assessment invalid. (d) The rate per acre of the assessment upon each tract assessed, or if no assessment is made upon any tract or area composed of more than one tract, a statement of that fact. (e) The rate per acre of the assessment upon each tract assessed for the costs of the properties that are necessary to be used in connection with the generating of electric power, or if no assessment of the costs is made upon any tract or area composed of more than one tract, a statement of that fact. (f) The total amount of the assessment as computed. (g) Any other statement which may be required by the board at the time of transmitting the plans and specifications and costs of the work for the district.
