Assembly Bill 459 proposes amendments to the current law regarding county public works notice and competitive bidding thresholds. The bill raises the notice threshold from $5,000 to $10,000 and the bidding threshold from $25,000 to $50,000, with provisions for these amounts to be adjusted every five years based on inflation. Additionally, the bill introduces exceptions to the bidding requirements for public works aimed at providing housing for individuals placed on supervised release as sexually violent persons, as well as for improvements constructed by private individuals and donated to the county.

The bill also renumbers and amends existing statutes to clarify the bidding process and the conditions under which contracts may be awarded. Specifically, it stipulates that contracts exceeding the new bidding threshold must be awarded to the lowest responsible bidder, while those below the notice threshold can be let as the board directs. The legislation aims to streamline the bidding process for county public works projects while ensuring that certain exceptions are clearly defined.
