For capital expenditures and for the payment of indebtedness or rent, a governing body may, in addition to the levy and appropriation required under the provisions of §§ 22.1-94 and 22.1-95, levy a special county tax, a special district tax, a special city tax or a special town tax, as the case may be, on all property subject to local taxation. Such levy or levies shall be at such rate or rates as the governing body levying the tax may deem necessary for the purpose or purposes for which levied, except that where the tax is for raising funds for capital expenditures the rate shall not be more than $2.50 on each $100 of the assessed value of such property in any one year.
