According to the charter, the board of commissioners must set (by ordinance) regulations governing all purchases and public improvements. The board also must set the minimum cost of acquisitions and public improvements that triggers the requirement for formal sealed bids. The municipality may reject any bids.
Based on written recommendation of the city manager, and by unanimous resolution of those at the meeting, the board may authorize non-competitive contracts if it is clearly to the advantage of the city not to contract with competitive bidding.
The charter authorizes the board of commissioners to delegate by ordinance to the city manager the authority to enter into binding contracts on behalf of the city, without specific board approval, in routine matters and matters not having substantial long-term consequences (fiscal year expenditures less than $10,000).
The board may establish (again, by ordinance) all purchasing and contract procedures not addressed in the charter or other legislation.
