(a) In counties having a population of 1,000,000 or more, the electors may authorize the township board to contract with one or more municipalities in the township or with the county within which the township is located to furnish police protection in the unincorporated area of the township.

(b) The township board may declare the unincorporated area of the township a special police district for tax purposes. Proof of the declaration authorizes the county clerk to extend a tax upon the special police district in the amount specified in the annual township tax levy, but not to exceed a rate of .10% of the value of taxable property as equalized or assessed by the Department of Revenue.
