BACKGROUND
As part of the City's storm drain maintenance program, the City's storm drain at Foster Road and Carfax Avenue was analyzed via storm drain cleaning and video assessments to identify areas in need of repair to ensure continued drainage of stormwater runoff in the surrounding area. The existing corrugated metal pipe storm drains in the area were found to be deteriorated and beyond repair, requiring replacement with corrosion -resistant reinforced concrete pipe to ensure that the City can continue to use this infrastructure to provide storm drainage for the surrounding area. The project limits are shown on the project location map included as Attachment A.
ANALYSIS
{}nSeptember 0.2O25'the City Council approved plans and specifications and granted authority k)advertise the subject project forbids(AttoohmenLB).Aoopyofd)ep jecispenificmhonsisavo|ob|eforrevevvindhePubUo Works Department. The proposed storm drain improvements include: the removal and replacement of deteriorated metal storm drain pipe with 514 feet of new reinforced concrete storm drain along Carfax Avenue at the intersection with Foster Road and easterly on Foster Road to the Lower San Gabriel River; replacement of existing storm drain catch basin and junction structures; modification of the existing storm drain catch basin; and installation of catch basin connector pipe screens tocapture trash and debris and prevent them from reaching the City'screeks and The project was advertised in the Downey Patriot on April 23. 2026 and April 30, 2026 and published in Planet Bids.

The apparent low bidder was OrangeBlue General Contractors in the amount of $409,790 followed by the second low bid of Oppenheimer National in the amount of $417,398. However, in accordance with the Proposal Bidder's Qualifications Statement for the subject project, the contractor, acting as a prime contractor for a public agency, must have completed at least three storm drain pipeline construction projects within the last three (3) years.
Neither OrangeBlue General Contractor's Bid Proposal or Oppenheimer National's Bid Proposal contained three storm drain pipeline construction projects within the last three (3) years for which OrangeBlue General Contractor or Oppenheimer National were acting as a prime contractor for a public agency. Both OrangeBlue General Contractors and Oppenheimer National's Bid Proposals were subsequently deemed non -responsive. Therefore, the lowest responsive and responsible bidder is CEM Construction Corporation in the amount of $427,900 (Attachment C).
Staff reviewed the bid proposal and references provided by CEM Construction Corporation and found that CEM Construction Corporation has satisfactorily completed projects for the Cities of Alhambra, Inglewood, Laguna Beach, Orange, Santa Ana and others. CEM Construction Corporation's state contractor's license is "current and active," and this contractor is registered with the California Department of Industrial Relations (DIR) for Labor Compliance. Staff recommends that the City Council award a contract to CEM Construction Corporation for the construction of the Foster Road and Carfax Avenue Storm Drain Improvements, CIP No. 24-23.
Construction is anticipated to begin in July 2026 and be completed in October 2026.
This project is categorically exempt from the provisions of CEQA under Section 15302 Class 2(c).
