BACKGROUND <br /> Sycamore tank is an eight million gallon water storage tank below ground located at the <br /> end of Sycamore Creek Way that encompasses 1.3 acres. The site has two <br /> undeveloped grass hills that drain across the property. The existing site surface is <br /> primarily dirt with little vegetation. The existing drainage ditches silted over and required <br /> maintenance. A new concrete V-ditch was required to direct water from the south <br /> property line to the storm drain system on Sycamore Creek Way. The existing soil was <br /> amended and hydro seeded with native grass to prevent further erosion of the tank site. <br /> DISCUSSION <br /> The construction contract for this project was awarded to S.R.P. Company on August <br /> 20, 2013 for the amount of $62,990. Five change orders were issued totaling <br /> $2,949.78, within the approved contingency of $6,300. The change orders were for <br /> additional grading, additional storm drain pipe, minor irrigation improvements, and <br /> delays associated with conflicting work occurring at the tank site. <br /> The $100,000 Bi-Annual Erosion Control and Storms Repair CIP provides funding for <br /> various erosion control and storm damage projects. This project at the Sycamore Tank <br /> site was one of those projects. In addition, the Operations Services Center (OSC) <br /> purchased trash capture devices from Kristar Enterprises, Inc for $5,225 and installed <br /> them throughout town. The trash capture devices collect trash at the end of large <br /> culverts before entering open channels of water. The installation of the trash capture <br /> devices is part of the City's efforts to meet the NPDES general permit requirements. <br /> The OSC also hired Ponte Engineering to install energy dissipation and channel <br /> protection at the outfall of a 60" storm drain from Oak Tree Farms near Verona Bridge <br /> prior to going into the Arroyo De Laguna. The existing storm water flow had begun <br /> undermining the outfall structure and causing undercutting of the existing native <br /> channel. Large rip rap and boulders were installed to repair and support the outfall <br /> structure and prevent further erosion of the channel. <br /> All of the contract work has been completed to the City's satisfaction. This project is <br /> now complete and ready for City Council acceptance. Staff recommends the balance <br /> be returned to the fund balance of the Storm Drain Capital Improvement Fund. <br /> Page 2 of 3 <br />
