BACKGROUND INFORMATION: This project consists of furnishing and installing a pre -fabricated storm water trash handling system and other incidental and related work, all as shown on the plans and specifications for the project. The Shady Acres storm drain pump station serves 806 acres of developed land inside the B-1 Basin watershed (Exhibit A). The pump station is one of two locations in the City where storm water is discharged into the Woodbridge Irrigation District (WID) canal. In 2012, the City of Lodi entered into the "Third Amendment to 2003 Agreement for Purchasing of Water from Woodbridge Irrigation District by City of Lodi" with WID. In exchange for additional surface water banking opportunities, the City agreed to install a storm water trash handling system at the Shady Acres Pump Station. Currently, debris is discharged along with storm water into the WID canal by the pump station. The project objective is to improve water quality in the canal while complying with State mandated storm water permit requirements. The proposed design will remove oil, floating debris, trash and sediment from the storm water before it is discharged to the WID canal (Exhibit B and C). WID concurs with the system being proposed and will assist the City and the contractor as needed. It is expected the unit will require regular monitoring and bi-annual cleaning that will be performed by City crews. The specifications are on file in the Public Works Department. The planned bid opening date is June 18, 2015. The project estimate is $800,000. It is anticipated that the majority of the contract cost is in the installation of the trash handling unit due to restricted site access issues. FISCAL IMPACT: This project will increase the maintenance cost to the pump station for monitoring and maintenance of the trash handling unit. FUNDING AVAILABLE: Funding will be identified at pr Iect award. I Wu F.
