RECOMMENDATION
Title
APPROVE an increase in the Life of Project Budget (LOP) for Permeable Pavement and Bioretention Pilot Project (Project) in the amount of $1.16 million increasing the LOP from $940,000 to $2.1 million to complete construction of the Project.
Issue
ISSUE
In 2014, Metro applied for a Proposition 84 Grant Opportunity to implement a permeable pavement project at Division 4. In May 2014, the State Water Resource's Control Board (SWRCB) awarded Metro with a grant of $752,000 to implement its proposed permeable pavement and biorentention project with a local commitment from Metro of $188,000 for a total LOP of $940,000. This report recommends adopting a LOP budget with the necessary additional funding of $1.16 million to complete the Project.
The competitive low-bid prices for the construction component of the Project have been received and the winning bid would result in this higher forecast for the LOP. Staff believes the bids are representative of current market conditions and that a rebid would not result in lower pricing. Furthermore, without additional funds, Metro will have to relinquish grant funding back to the SWRCB and terminate current efforts related to a much needed pilot.
