In order to accomplish the purposes for which the district is created, the board of commissioners may:
(13) Whenever any work is to be let under the provisions of this Chapter, the contract for which will exceed the value of two thousand dollars, the board of commissioners of the district shall proceed to provide through the department of public works, proper specifications for the performing of said work, which specifications shall receive the approval of the board of commissioners of the district. After the adoption of the specifications thus approved the board of commissioners of the district shall advertise for bids to do the work according to the plans and specifications prepared by the department of public works, which advertisement shall appear once a week for the full term of thirty days in a newspaper of Jackson Parish, as well as any other paper or papers in the discretion of the board of commissioners. Such advertisement shall state the place where the bids will be received, the time and place where the bids will be opened, and a general outline of the work expected to be performed. Every bid shall be accompanied by a certified check of the bidder in an amount equal to five percent of the amount of the bid, which check shall be forfeited to the board of commissioners of the district, should the bidder to whom such contract is awarded fail to enter into the contract required within ten days after notice to do so from the board of commissioners awarding the work. The checks of all unsuccessful bidders shall be returned after the contract is awarded. All bids submitted shall be addressed to the Board of Commissioners of the Jackson Parish Watershed District and shall be publicly opened and read at the time stated in the advertisement. The governing authority of the district may reject any and all bids, if, in its opinion, it is to the best interest of the district to do so, but whenever a contract is awarded, unless for cause which in its discretion is deemed sufficient, it shall be awarded to the lowest responsible bidder. The bidder to whom such contract is awarded shall be required to furnish bond of a surety company authorized to do business in Louisiana, or other good and solvent surety, in the sum equal to one-half of the amount of the contract awarded, conditioned that such work shall be performed in accordance with the plans and specifications of the Department of Public Works and the terms of the contract, and containing such other stipulations and provisions as may be required by the authority granting the contract. The awarding of the contract to a successful bidder will be binding upon both, even though for some cause there should be no signing of the actual contract.
