CA Gov't Code Section 53329.5

(a)

The owners of three-fourths of the area of lands taxed or liable to be taxed, or their agents (who shall declare under penalty of perjury that they are such owners or agents), shall not be required to present sealed proposals or bids when the legislative body calls for bids preparatory to letting a contract or contracts to do work financed pursuant to this chapter, but may, within 10 days after the publication of the notice of the award of the contract, elect to perform the work and enter into a written contract to do the whole work at prices not exceeding the prices specified in the bid of the bidder to whom the contract was awarded, and all work done under the contract shall be subject to any regulations as may be prescribed by the legislative body.

(b)

If the owners elect not to perform the work and not to enter into a written contract for that work within 10 days of publication of the notice of the award of the contract, or to commence the work within 15 days after the date of the written contract entered into between the owners and the legislative body, and to continue that work with diligence to completion, as determined by the legislative body, a contract shall be entered into by the legislative body with the original bidder to whom the contract was awarded at the prices specified in his or her bid.

(c)

If, in the opinion of the legislative body, the public interest will not be served by allowing the property owners to enter into a contract in accordance with subdivision (a), the legislative body may so provide in the resolution of intention adopted pursuant to Section 53321.
