There is hereby established a special homestead exemption whereby sewer rates charged to a dwelling unit owned and occupied by a person 65 years of age or older or owned and occupied by a permanently or totally disabled person, provided that the sum of all income of all adults occupying the dwelling unit falls below $35,000 per annum, shall be 75% of the sewer rate established pursuant to this chapter. For the purposes of this section, “income” shall have the same meaning as in Section 128.03101. (Ord. 9-13A. Passed 5-20-2013.)
