The Council shall establish, by ordinance, the procedures for
the purchase and sale of personal property. Such ordinance may provide
for centralized purchasing on behalf of the city. The ordinances shall
also provide the dollar limit within which purchases of personal property
may be made without the necessity of securing competitive bids, and
the dollar limit within which purchases may be made without the necessity
of Council approval. No purchase of personal property shall be made
unless a sufficient unencumbered appropriation is available to pay
that part of the cost thereof which will be due for payment during
the fiscal year in which the purchase is made.
An officer or employee of the city who intends to have business dealings with the city, whereby he may derive any income or benefits, other than such as are provided as remuneration for his official duties or employment, shall file with the Clerk a statement under oath, setting forth the nature of such business dealings, and his interest therein. The statement shall be filed with the Clerk not less than 10 days before the date when action may be taken by the Council or any other agency of the city upon the matter involved. The statement shall be spread upon the proceedings of the Council for the meeting at which it is received and published in full therewith. In each case where the type of dealings with the city is on a continuing basis, involving more than one or a sequence of transactions described in the statement, each such statement shall stand for and apply to such transactions for a period of one year, and may be renewed at the end of each one-year period for so long as such transactions continue. Each such renewal shall be spread upon the proceedings of the Council and published as in the case of the original statement. In the event that the interest of any officer or employee of the city in any business dealings with the city changes at any time, he shall file a statement thereof as herein required, which statement shall also be spread upon the proceedings of the Council and published as herein required. Approval of any such business dealings shall require a concurring vote of at least five members of the Council, not including any member who is disqualified under Section
4.5 (h) of this charter. Any business dealing made in violation of this section shall be void.
