TITLE
Recommendation to adopt Plans and Specifications No. R-6755 for the construction of storm drain pollution trap nets at pump station No. 12; and authorize City Manager to award and execute the contract with Humphrey Constructors, in an estimated amount of $245,500 plus a 15 percent contingency in the amount of $36,825, if necessary and if funds are available, for a total of $282,325, and any amendments thereto. (District 9)
DISCUSSION
On July 13, 2009, the State Water Resources Control Board (SWRCB) and the City of Long Beach entered into a project finance agreement through the Clean Water State Revolving Fund under the American Recovery and Reinvestment Act (ARRA). This project involves the construction of a trash net system at City-owned Pump Station No. 12 located at the junction of the 710 and 91 freeways. A vicinity map of the area is attached as Exhibit A. The trash net system will capture and remove trash and debris prior to entering the pumps, thereby significantly reducing trash and debris discharged into the Los Angeles River.
The project includes removing the existing trash rack, constructing a storm drain pollution trap netting system within an existing pump station forebay/trash pit, including a steel frame to receive a manufactured netting system, furnishing and installing the manufactured netting system components, modifications to the existing trash pit, and construction of trash racks.
City Council adoption of the plans and specifications and award of the contract to the lowest responsible bidder are being recommended as detailed in Exhibit B. The project was advertised for bid on October 23, 2009, and bids were opened on November 19, 2009. Information regarding the lowest responsible bidder, Humphrey Constructors, is provided on the attached contract awards document. In accordance with the California Environmental Quality Act, Categorical Exemption number CE-592-06 has been issued for this project.
This matter was reviewed by Deputy City Attorney Amy Burton on November 23, 2009 and Budget and Performance Management Bureau Manager David Wodynski on November 20, 2009.
SUSTAINABILITY
This trash net system, similar to those installed at other City pump stations (SD1, SD3, SD4, SD5, & SD6), has proven to be very effective at capturing trash, sediment and green waste. An additional benefit derived from the netting system is that bacteria attached to the trash and debris will also be captured, improving the quality of the stormwater runoff water being discharged to the Los Angeles River.
TIMING CONSIDERATIONS
In accordance with the project finance agreement, a Notice to Proceed must be issued to the contractor by December 31, 2009. City Council action on this matter on December 15, 2009 will authorize commencement of this Public Works project. Construction is projected to begin in February 2010 and should take approximately 60 working days.
FISCAL IMPACT
The contract award is for an estimated amount of $245,500 plus a 15 percent contingency amount of $36,825, if necessary and if funds are available. Sufficient funds to cover the contract are budgeted in the Capital Projects - Fund (CP 201) in the Department of Public Works (PW).
