Sinacori, Assistant City Engineer 949- 644 -3342 or Msinacori @newportbeachca.gov SUBJECT: BIG CANYON RESERVOIR FLOATING COVER REPAIRS ISSUE The Big Canyon Reservoir was equipped with a floating cover in 2005, as required by the State Department of Health Services. The cover was provided with a 20 year prorated material only warranty. This past year, several defects have been discovered necessitating repairs though the cover is only six years old. Staff has expended approximately $120,000 from water maintenance and repair accounts to fund necessary repairs which were not anticipated in this year's budget. Staff is requesting that the fund be restored so normal maintenance activities can continue through the rest of the fiscal year. :7*i]i51PF4►I1 `11611 Authorize budget amendment transferring $120,000 from the unappropriated Water Enterprise Fund Reserve to Maintenance and Repair Account No. 5500 -8156 ($85,000) and Professional and Technical Services Account No. 5500 -8080 ($35,000). DISCUSSION On February 10, 2004, the City Council authorized the award of the Big Canyon Reservoir Covering and Disinfection Facilities contract to Banshee Construction Company. The contract provided for the installation of a floating cover and new disinfection facilities to comply with a mandate from the State Department of Health Services. The City Council accepted the floating cover and facilities on October 25, 2005. The floating cover was provided with a 20 year material only prorated warranty. In the Spring of 2010, the operations staff begin to notice deterioration in areas of the floating cover in and around the hatches and along the mixing pump cages in the four corners of the reservoir. Holes could be seen in several locations. The manufacturer of the cover material, The Cooley Group, was notified that their material was not performing as expected and was showing signs ( "Cooly ") of premature failure. Independent testing of the material by Cooley and the City determined that the material has completely lost its ultraviolet (UV) protection. A UV protection additive is included in the cover material as part of the manufacturing process. Essentially no UV additive was detected in the testing, thus we believe this is the reason for the cover material to show signs of premature failure. Big Canyon Floating Cover Repairs February 22, 2011 Page 2 Cooley has cooperated with the City to provide new cover material to allow the necessary repairs to take place. To date staff has expended $85,000 in cover repair efforts and also contracted with a cover expert for $35,000 to oversee the repairs and provide recommendation to the City in its negotiations with Cooley. Staff is now working with the City Attorney's office to seek recovery from Cooley of expenses related to the premature failure of the cover and related repairs and replacement. Staff anticipates that the cover will need to be completely replaced within the next few years, as the cover will most likely deteriorate beyond a point to perform anticipated normal and required maintenance efforts on the cover. ENVIRONMENTAL REVIEW Staff recommends that the City Council find this action is not subject to the California Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) (the activity will not result in a direct or reasonably foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as defined in Section 15378) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no potential for resulting in physical change to the environment, directly or indirectly. PUBLIC NOTICE Notice for this budget amendment was provided in accordance with the Brown Act 72 hours prior to the City Council meeting. FUNDING AVAILABILITY The repair and consultant cost expended to date was not anticipated in this year's water enterprise maintenance and operations budget. Staff is requesting approval of the attached budget amendment transferring $120,000 from the unappropriated Water Enterprise Fund Reserve to the Water Maintenance and Repair Account No. 5500 -8156 ($85,000) and Professional and Technical Services Account No. 5500 -8080 ($35,000). Funds are available in the Water Enterprise Reserve to accommodate this proposed budget amendment. Any warranty reimbursement funding received from Cooley will be returned to the Water Enterprise Fund Reserve.
