Section 384.7 - Capital improvements fund1. A city may establish a capital improvements reserve fund, and may certify taxes not to exceed sixty-seven and one-half cents per thousand dollars of taxable value each year to be levied for the fund for the purpose of accumulating moneys for the financing of specified capital improvements, or carrying out a specific capital improvement plan.2. The question of the establishment of a capital improvements reserve fund, the time period during which a levy will be made for the fund, and the tax rate to be levied for the fund is subject to approval by the voters, and may be submitted at any city election upon the council's motion, or shall be submitted at the next regular city election upon receipt of a valid petition as provided in section 362.4.3. If a continuing capital improvements levy is established by election, it may be terminated in the same manner, upon the council's motion or upon petition. Balances in a capital improvements reserve fund are not unencumbered or unappropriated funds for the purpose of reducing tax levies. Transfers may be made between the capital improvements reserve fund, construction funds, and the general fund, as provided in rules promulgated by the city finance committee created in section 384.13.
