Notwithstanding any other provision of law, each grant of aid under Chapter 5 (commencing with Section 13000) shall be increased in the amount of two dollars ($2), as a basic need of the recipient. Grant increases provided pursuant to this section are specifically intended to assure that the tax shift provisions of the Property Tax Relief Act of 1972 will not work a hardship on welfare recipients. Such grant increases shall not replace, but are in addition to any other grant, including any cost-of-living adjustment or any grant for special needs for which recipients affected by this section are or may become eligible.
