installation of additional fire hydrants to enhance fire water protection in the area; installation of new copper water service lines; and replacement of old water meters with new remote -read advanced water meters along the project limits to improve water meter reading efficiencies.
In addition, one change order totaling $38,000 was approved for the replacement of additional water valves and fittings on the adjacent streets that were affected by the project work. The final construction contract amount was $357,400.
The Stamps Road Water System Improvements project has been completed in accordance with the approved plans and specifications, and staff recommends that the City Council accept the project as complete and authorize the Director of Public Works/City Engineer to file the Notice of Completion with the Los Angeles County Recorder's Office. Complete resurfacing of the southerly half and slurry sealing of the northerly half of the Stamps Road project limits pavement will follow over the next year under a separate construction contract.
